Objective To study the anti-inflammatory mechanism of the Penyankangshuan (PYKS) in treating chronic pelvic inflammation. Methods After model rats with endometritis were established successflly, 6 groups were formed which were the high, the middle and the low dosage groups of the PYKS, the KFXYS (a kind of patent medicine has a similar effect) group, the model group, the normal group. The treated rats were continuously rectal administration 3 weeks, the expression of NF-?B, Caspase-3 and MMP-2 were observed in the high, the middle dosage groups of the PYKS, the KFXYS group, the model group and the normal group with immunohistochemistry. Results The PYKS obviously raised the expression of Caspase-3 and MMP-2, but decreased the expression of NF-?B. Conclusion The anti-inflammatory mechanism of the PYKS possibly raised the expression of Caspase-3 and MMP-2 of mice endometrial cells, decreased the expression of NF-?B, so as to reduce inflammation soakage in excess and formation of inflammatory medium, accelerate apoptosis and reduce local inflammation.

0.05). Conclusions NYKFS can inhibit the synthesis of ER and PR in cells of ectopic endometrium to treat endometriosis and have certain accommodation on abnormal expression of ER and PR in eutopic endometrium.

Objective To investigate the relationships among estrogen,transforming growth factor ?(TGF?) and smooth muscle cells in human prostatic tissue by cell experiment. Methods Eleven strains of prostatic stromal cells were cultured successfully from BPH patients,and stimulated by estradiol(E 2).Cell proliferations were observed by MTT,and mRNA expressions of TGF? 1,TGF? 2 and smoothelin were observed by RT-PCR. Results E 2 could not influence TGF? 1 expressions in prostatic stromal cells,but could upregulate expressions of TGF? 2 and smoothelin;and expression values of TGF? 2 and smoothelin had a positive correlation. Conclusions E 2 can influence growth and differentiation of prostatic smooth muscle cells through induction of TGF? 2 expression.

Objective To compare the clinical effect of ERCP and PTCD metal stent implantation in the treatment of malignant obstructive jaundice.Methods 42 patients who were treated successfully with ERCP biliary metal stent implantation in the treatment of malignant obstructive jaundice were selected as the ERCP group,38 patients who were successfully treated with PTCD biliary metal stent implantation in the treatment of malignant obstructive jaundice,were selected as the PTCD group.The changes of alanine aminotransferase,aspartate aminotransferase,direct bilirubin,total bilirubin content and complications of patients were compared between two groups.Results On the third day of the ERCP group after operation,alanine aminotransferase,aspartate aminotransferase,direct bilirubin,total bilirubin levels were (203.94 ±12.53)U /L,(180.94 ±17.53)U /L,(185.63 ±17.53)μmol/L,(240.41 ± 18.79)μmol/L respectively,those of the PTCD group were (230.63 ±13.95)U /L,(209.19 ±19.74)U /L,(192.52 ± 16.93)μmol/L,(266.83 ±20.73)μmol/L respectively,which were significantly lower than before operation(all P <0.05).The incidence rate of complications of ERCP group was 4.76%,which was significantly lower than 23.68% of the PTCD group(χ2 =6.02,P <0.05).Conclusion ERCP and PTCD biliary metal stent placement in the treatment of malignant obstructive jaundice can effectively relieve the obstruction.The incidence of complications of PTCD is slightly higher in both common complications.

Objective To investigate the effect of Qingjing Capsule (QC) in treating advance menorrhea (AM) and to evaluate its safety. Methods Double- blind, double- imitating, parallel- controlled and randomized trial was performed in 63 cases of AM with deficiency- heat syndrome.Thirty- two cases was in QC group(Group A) and other 31 in Gujing pill group(Group B).The menstrual cycle, clinical symptoms and signs, basal body temperature (BBT), serum levels of estradiol (E2) and progesterone and endometrium biopsy were observed to evaluate the effects of QC. Results The short- term markedly- effective rate was 90.63% and 77.42% and the short- term effective rate was 96.88% and 93.55% in Group A and Group B respectively. The long- term markedly- effective rate was 83.87% and 67.74% and the long- term effective rate was 93.55% and 80.65% in Group A and Group B respectively. The long- term markedly- effective rate in QC group is superior to that in Gujing pill group, the differences being significant(P

Objective To investigate the effect of methylguanidine and 1-methylhydantoin on cells cytotoxicity, apoptosis in human renal tubular epithelial cell line (HK-2). Methods Human PTEC cell line HK-2 was used in this study. HK-2 was cultured and divided into 3 groups: Norma1 control group (A), methylguanidine group(B) and 1-methylhydantoin group (C). The cell inhibitory rate of HK-2 was detected by MTT method. The cytotoxicity of methylguanidine to HK-2 was determined by NAG release test. Cell apoptosis was evaluated by using Hoechst stain and FACS with Annexin-V/PI. Results The OD value and NAG concentration of creatinine, methylguanidine and 1-methylhydantoin group were compared with normal control group. OD value decreased and NAG concentration significantly increased(0.188±0.011, 0.176±0.010 vs 0.545±0.021, F＝1557.74, P＜0.01; 20.488±0.473, 22.225±0.565 vs 5.125±0.198, F＝3848.22, P＜0.01). By Hoechst stain, pycnosis and apoptotic body could be found when HK-2 was cultivated in methylguanidine 1-methylhydantoin group. In methylguanidine, 1-methylhydantoin group apoptotic HK-2 apparently increased, compared with that in control group (18.23±1.1581, 20.22±1.1433 vs 2.473±0.321, F＝526.06, P＜0.01). Compared with group B, the OD value in group C decreased significantly (0.176±0.010 vs 0.188±0.011,t＝2.26, P＜0.05), NAG concentration increased significantly (22.225±0.565 vs 20.488±0.473,t＝-6.67, P＜0.01), and apoptotic rate in-creased significantly (20.22±1.1433 vs 18.23±1.1581,t＝-2.762, P＜0.05). Conclusions 1-methylhydantoin has more powerful cytotoxic effect to renal tubular epithelial cells than that of Methylguanidine.

AIM To study the therapeutic effects of Neiyi Kangfu Tablets (Trionycis Carapax,Ostreae concha,Rhei Radix et Rhizoma,etc.) on adenomyosis and its possible mechanism of action.METHODS The mouse model for adenomyosis was set up by the pituitary allograft,and received the gavage of Neiyi Kangfu Tablets,Dan'e Fukang Decoction (Salviae miltiorrhizae Radix et Rhizoma,Curcumae Rhizoma,Paeoniae Radix rubra,etc.) and gestrinone,respectively,for three months.Western blot,real-time PCR,IHC were used to measure the expression of GPER-Ras-STAT3 in ectopic endometrium and entopic endometrium.RESULTS High doses of Neiyi Kangfu Tablets could significantly lower GPER protein and gene expression;down-regulate the Ras and STAT3 protein expression;reduce the lesion severity score of ectopic tissue morphology.Its curative effect was better than Dan'e Fukang Decoction and gestrinone.CONCLUSION Neiyi Kangfu Tablets may control the development of ectopic lesions by inhibiting the GPER-Ras-STAT3 pathway activity and weakening the production of estrogen.

Objective To investigate the clinical, pathology, diagnosis and treatment of the lower urinary system dysfunction among chronic recreational ketamine abusers. Methods From 2000-2008, 20 ketamine abusers(14 men and 6 women; mean age, 22.3 years), from 3 hospitals in Guangzhou and Hongkong, and suffering from lower urinary tract dysfunction was reported. All of them had abused ketamine for 1 to 4 years, and presented with severe lower urinary tract symptoms. Complaint of severe frequency, urgency, urge incontinence, and painful haematuria was common. Urine cultures were negative. Six men suffered from severe dysuria. B ultrasound examination of 16 cases demonstrated the presence of bilateral hydronephrosis. Fourteen IVU and 10 CT investigations demonstrated the presence of bilateral hydronephrosis, bladder contraction, and 1 case showed papillary necrosis of the kidney. Different levels of abnormal liver function and chronic/acute renal failure were observed. All of the patients were required to withdraw the narcotics and the experimental medicine were given. Results The biopsies of 6 cases demonstrated the cystitis. Twelve cases' symptoms were reversible after these patients stopped or reduced the frequency and amount of ketamine abuse. Pentosan polysulfate sodium and sodium hyaluronate solution relieved the symptoms of 6 patients. Conclusions "Street ketamine" associated urinary system dysfunction might be a kind of in flammatory process involving the upper and lower urinary tract. Underlying aetiology and treatment methods necessitate further study.

Objective To investigate the clinicopathological features, postoperative survival and prognostic influencing factors of male patients with hepatocellular carcinoma (HCC). Methods The clinicopathological features and the follow-up data of 155 male HCC patients who received hepatectomy from Jan. 1995 to Dec. 2002 were retrospectively analyzed and the prognostic influencing factors were defined by uni-and multi-variate analysis. Results Compared with 24 female patients at the same period, males were about six-year older and both of their hepatitis B surface antigen (HBsAg) and liver cirrhosis positive rates were higher (P

The sequelae of pelvic inflammatory disease (SPID) is a gynecological disease that seriously affects the reproductive health and quality of life of women of childbearing age,which is repeated and intractable. In traditional Chinese medicine (TCM),it belongs to the categories of women's abdominal pain,zhengjia,infertility,etc. The uterus xuanfu-collaterals can maintain the orderly progress of female physiological function by adjusting the circulation of qi and liquids,and also play an important role in the pathological process of SPID. If the opening and closing of the uterus xuanfu-collaterals are orderly,and the qi and liquids are circulating smoothly,the pelvic microcirculation will maintain a balance of homeostasis. If the uterus xuanfu-collaterals are stagnated,the qi and liquids do not circulate smoothly,the pelvic microcirculation will be disordered,leading to the occurrence of SPID. Therefore,from the perspective of the pathogenesis of xuanfu-collaterals stasis,taking opening xuanfu and dredging collaterals as the treatment method,it can be used to smooth qi,relieve stagnation,supplement deficiency,and remove blockage in order to restore the microcirculation in the pelvic region,which can provide new ideas and methods for the treatment of SPID with TCM.
