Objectives The purpose of this study was to analyze recent traditional Chinese medicine clinical studies for treatment of childhood obesity. Methods We analyzed 11 clinical studies from January, 2000 to March, 2018 about childhood obesity from the China Academic Journal (CAJ) and China National Knowledge Infrastructure (CNKI). All selected studies were Randomized Controlled Trials and analyzed in order of publication year, demographic information, treatment method, evaluation methods, results, adverse reactions and relapse after treatment discontinuation. Results The main Traditional Chinese Medicine (TCM) treatment was the herbal decoctions, granules and pills. In most studies, the total efficacy of the treatment group was reported to be higher than that of the control group. Adverse reactions were found in small number of studies. Frequently used medical herbs were Crataegi Fructus (山?), Atractylodis Rhizoma (蒼朮), Citri Pericarpium (陳皮), Poria (茯?), and Nelumbinis Folium (荷葉). Also, Water-draining and swelling-dispersing medicinal (利水退腫藥), Qi-regulating medicinal (理氣藥), Resolving dampness with aroma medicinal (芳香化濕藥), Blood-activating and stasis-dispelling medicinal (活血祛瘀藥), Qi-tonifying medicinal (補氣藥), and Digestant medicinal (消食藥) were commonly used. Conclusions This study showed that traditional Chinese medicine, especially herbal medicine treatment can be effective and safe option for treating childhood obesity. These research results can be utilized in other clinical studies as well as in treatment of childhood obesity. Additional well-designed randomized controlled trials and systematic reviews are need to confirm the conclusion.

The pronuclear injection of metallothionein-human growth hormone (MT-hGH) gene into rabbit zygotes was performed to establish in vitro developmental system and to detect the presence of the injected gene by nested PCR. Mature female New Zealand White rabbits were superovulated by eGG and hCG treatments. The rabbits were mated and the zygotes were collected from the oviducts 18-22 h after hCG injection by flushing with D-PBS. Two to three picoliters of MT-hGH gene was microinjected into male pronuclei. The foreign gene-injected zygotes were cultured in TCM-199 or RD mediurn containing 10% FCS with a monolayer of rabbit oviductal epithelial cefls in a 5% $CO_2$ incubator. The presence of injected DNA in rabbit embryos or blastomeres at different developmental stages .vas detected by a nested PCR analysis. The results are summarized as follows ; 1.The developmental rate of the MT-hGH gene-injected zygotes to blastocyst was significantly higher in TCM-199 medium (68.1%) than in RD medium (42.9%). 2.The gene injection into pronuclei at 18 or 22 hours post hCG treatment during pronuclear stage did not much affect on the in vitro development of the rabbit embryos. 3.The rate of gene-positive embryos detected by the nested PCR analysis was significantly decreased when they developed to blastocysts. The results indicate that the screening of transgene in rabbit embryos by nested PCR analysis could be a prornisible method for the preselection of transgenic embryos. Furthermore, the preselection of transgenic embryos would greatly reduce hoth the cost and effort of production of transgenic animals.

In vitro maturation and activation of oocytes are primary steps towards biotechnological manipulation in embryology. The objectives of the present study were to determine the oocyte recovery rate per ovary, in vitro maturation rates of oocytes and rates of parthenogenetically activation of matured oocytes in Black Bengal goats. All visible follicles were aspirated to recover follicular fluid from individual ovaries (number of ovaries = 456). The immature cumulus oocyte complexes (COCs; n = 1289) were cultured in tissue culture medium (TCM)-199 supplemented with 10% (v/v) fetal bovine serum (FBS) for 27 hours at $39^{\circ}C$ with 5% $CO_2$ in humidified air. The matured oocytes (n = 248) were activated with 5 ${\mu}M$ ionomycin for 5 minutes followed by treatment with 2 mM 6-dimethylaminopurine (6-DMAP) for 4 hours. After activation, oocytes were cultured for another 14 hours in TCM-199 supplemented with bovine serum albumin (BSA) at $39^{\circ}C$ with 5% $CO_2$ in humidified air. The pronucleus formation in activated oocytes was determined by staining with 1% orcein (whole mount technique). Matured oocytes (n = 176) without activation stimuli were used as control. The mean number of oocytes recovered per ovary was $3.5{\pm}0.5$. The proportion of oocytes matured in vitro, confirmed by the presence of first polar body, was $42.1{\pm}4.7%$. Parthenogenetic activation, evidenced by formation of pronucleus, occurred in $37.2{\pm}15.8%$ of matured oocytes. No pronucleus formation was observed in control oocytes. In conclusion, a combination of ionomycin and 6-DMAP induces activation in one third of Black Bengal goats' oocytes.

A simple procedure for rapid isolation of plasmid DNA from lactobacillus species and streptococcus species is described. Lactic acid bacteria were cultured in the TCM broth containing 0.5％ glycine and plasmid DNA was isolated from cells treated with mutanolysin by alkaline-detergent lysis method. Good results for releasing and isolating plasmid DNA from lactobacillus species were obtained by treatment of cells with 30$\mu\textrm{g}$ of mutanolysin per ml at 37$^{\circ}C$ for 5 to 10 min. For the streptococcus species, the optimum conditions were slightly different. The procedure could be used for rapid characterization of plasmid DNA in Lactobacillus casei, Lactobacillus acidophilus, Lactobacillus helveticus, Streptococcus lactis, Streptococcus faecalis, Streptococcus faecium, and Streptococcus cremoris strains. Using this procedure, plasmids isolated from $1.5m\ell$ cultures could readily be visualized in agarose gel.

In this study, 4 gases containing typical chlorinated volatile organic compounds (VOCs) were treated by ultraviolet (UV) irradiation. The typical chlorinated VOCs are dichloromethane (DCM), trichloromethane (TCM), carbon tetrachloride (CTC) and trichloroethylene (TCE). The removal efficiency (RE) and the products of chlorinated VOCs by UV irradiation are investigated. At this time, 2 types of background gas (air and nitrogen) were used to figure out the RE by photooxidation and photolysis. The specification of UV-lamp used in this study was low-pressure mercury lamp emitting wavelength of 185~254 nm. The experimental conditions were set as initial VOC concentration of $180{\pm}10ppm$, empty bed retention time (EBRT) of 53 s, temperature of $23{\pm}2^{\circ}C$ and relative humidity of $65{\pm}5%$. In the photolysis condition with nitrogen ($N_2$) as background gas, the averaged RE of the 4 types of chlorinated VOCs was about 24% higher than that with photooxidation; and the REs of VOCs except CTC were confirmed as >99%. The composition of off-gases after UV photooxidation in air was investigated and several intermediates from DCM, TCM and TCE were detected by GC/MS. Among them, phosgene which is a toxics was detected as an intermediate of TCM. In addition, the concentration of carbon dioxide ($CO_2$) in the off-gases was measured to calculate the mineralization rate (MR). With the photooxidation, TCE showed the highest RE (>99%) while MR was the lowest (17%); and the MR of DCM was the highest (86%). In addition, particulate matters (PM) in the off-gases was also detected and high concentrated $PM_{10}$ ($21,580{\mu}g{\cdot}m^{-3}$) and $PM_{2.5}$ ($6,346{\mu}g{\cdot}m^{-3}$) were detected in TCE off-gas. More than 99% of the chlorinated VOCs could be removed using UV254-185 nm lamp, while it is necessary to conduct further studies on the production and treatment of secondary pollutants.
