OBJECTIVETo study the clinical efficacy of Chinese herbal retention enema combined with intrauterine douching for patients with endometritis diagnosed by hysteroscopy. They failed in in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI)-embryo transfer (ET) treatment.

METHODS131 patients received hysteroscopy after they failed in routine IVF/ICSI-ET treatment. Of them, 66 patients diagnosed as endometritis were enrolled as the test group and 65 patients without endometritis were enrolled as the control group. Chinese herbal retention enema combined with intrauterine douching was performed on patients in the test group before the next IVF/ICSI, while direct IVF/ICSI was performed on those in the control group. The embryo implantation rate and the clinical pregnancy rate were compared between the two groups.

RESULTSThe clinical pregnancy rate and the embryo implantation rate were 48.5% and 24.2% respectively, while they were 29.2% and 14.9% respectively in the control group, showing significant difference (P < 0.05).

CONCLUSIONChinese herbal retention enema combined with intrauterine douching could improve the embryo implantation rate and the clinical pregnancy in patients with endometritis.

OBJECTIVETo observe the effect of Jiangya Capsule (JYC) on serum levels of nitric oxide synthase (NOS) activity and malondialdehyde (MDA), and plasma concentration of neuropeptide Y (NPY) and homocysteine (Hcy) in patients with senile simple systolic hypertension.

METHODSRandomized, double-blinded controlled method was adopted, the patients were divided into two groups, the treated group treated with JYC and the control group treated with Nimodipine. Changes of blood pressure, serum level of NOS and MDA, and plasma concentration of NPY and Hcy were observed.

RESULTSThe effect of lowering blood pressure in the two groups were similar with insignificant difference (u = 0.24, P > 0.05). The total effective ratio in alleviating TCM syndrome was 90% (18/20) in the treated group and 60% (9/15) in the control group, comparison between them showed significant difference (u = 2.18, P < 0.05). After treatment, the NOS activity increased and MDA, NPY and Hcy levels decreased in the treated group, which showed significant difference as compared with those before treatment, and the improvement were better than those in the control group (all P < 0.05 or P < 0.01). While in the control group after treatment, only level of MDA was lowered significantly (P < 0.05).

CONCLUSIONJYC has good effect in treating senile simple systolic hypertension, it also could increase the NOS activity, lower the serum MDA level, obviously reduce the plasma concentration of Hcy and NPY.

AIM:We generated transgenic mice of NKCC1-/-(homozygous mutant),NKCC1+/-(heterozygous)and NKCC1+/+(wild-type)that have a targeted disruption in the NKCC1 gene to investigate the role of Na-K-2Cl(NKCC1)channel in auditory function of the inner ear.METHODS:Hearing threshold and endocochlear potential(EP)were measured in the NKCC1-/-,NKCC1+/-and NKCC1+/+ mice by auditory brainstem response(ABR)and EP recordings,respectively.The inner ears of the mice were removed and examined morphologically with the light microscope.RESULTS:The auditory function of NKCC1+/+ mice was normal,the mean value for ABR thresholds in response to click sound was [(23.13?3.78)dB,SPL],EP was(98?16)mV.The mean value for ABR thresholds to click sound was elevated in NKCC1+/-mice [(38.49?12.29)dB,SPL],relative to that significantly increased in NKCC1+/+ mice(P

Objective To evaluate the clinical effect of reduced glutathione in protecting the liver function for patients with hepatocellular carcinoma (HCC) after receiving international therapy.Methods The clinical data of 110 HCC patients,who were admitted to authors' hospital during the period from January 2010 to June 2013,were retrospectively analyzed.According to the random number table method the patients were divided into the control group (n=50) and the treatment group (n=60),and transcatheter arterial chemoembolzation (TACE) and transcatheter arterial infusion (TAI) were carried out in all patients.After the treatment,intravenous infusion of 2.0 g vitamin C,0.2 g vitamin B6,2.0 g inosine,and 250 ml branched chain amino acid was employed per day for one week for the patients of both groups,and additional intravenous dripping of 1.8 g reduced glutathione (added in 250 ml of 5％ glucose solution) was adopted for the patients of the treatment group.Various liver function indexes were tested before and one week after the treatment,the results were compared between the two groups.Results Before the treatment,no obvious differences in the hepatic functions and in the clinical condition existed between the two groups.One week after the treatment,in both groups the aminotransferase (ALT and AST) and total bilirubin (TBIL) were significantly increased when compared with the preoperative data (P＜0.05),while the serum pre-albumin (PA) was remarkably decreased when compared with the preoperative data (P＜0.05);these changes of various indexes in the treatment group were apparently better than those in the control group (P＜0.05).Conclusion The use of reduced glutathione can effectively relieve the liver function damage caused by interventional therapy in HCC patients,therefore,reduced glutathione has a very good clinical application value.

OBJECTIVETo construct T vectors based on Xcm I recognition site and optimize the PCR fragments for its ligation.

METHODSWe firstly cloned the human histone H4 cDNA containing one Xcm I recognition site at both its 5' and 3' end into pCDNA 3.0 vector and then generated T vector with pCDNA 3.0 backbone by cutting the recombinant plasmid with Xcm I. To increase the ligation efficiency, the primers were firstly phosphorylated before DNA fragments amplification and then the PCR products were treated with Taq DNA polymerase and dATP after PCR amplification. Two DNA fragments with the length of 312 bp and 1 329 bp were ligated to it and the ligation mixture was transformed into E. coli DH5α competent cells and the positive rates of the transformants were evaluated by PCR and DNA agarose gel electrophoresis.

RESULTSOur results showed that the T vector produced by our method could ligate to the target DNA fragments with high efficiency. Besides, the phosphorylation state of the primers used for PCR amplification is also an important factor determining the cloning efficiency. What's more, as for longer DNA fragments, retreatment with Taq DNA polymerase and dATP after PCR amplification and purification could improve the ligation efficiency significantly.

CONCLUSIONOur protocol may overcome the dependence on blue/white screening to get positive clones and provide a potent way to generate T vectors and ligate them to the target PCR fragment.
