Objective To observe the effect of stageⅢdiabetic nephropathy(DN)treated by Qizhi Jiangtang capsule and explore its potential mechanism. Methods According to digital table method,the patients who conformed to the diagnostic criteria of stageⅢDN were randomly divided into two groups:an experiment group and a control group. All the patients in the two groups took elution treatment for 2 weeks,and then were treated with western basic therapy. The patients in the experiment group were administered orally with Qizhi Jiangtang capsule(2.5 g once, 3 times a day),while those in the control group treated with valsartan 80 mg,once a day. Urine microalbumin(mALB), mALB/urine creatinine(UCr),β2-microglobulin(β2-MG),α1-microglobulin(α1-MG)were observed in the two groups,endothelin-1(ET-1),nitric oxide(NO),thromboxane B2(TXB2),6-keto prostaglandin F1α(6-keto-PGF1α) were also determined. Serum creatinine(SCr),blood urea nitrogen(BUN),serum cystatin-C(Cys-C),retinol-binding protein(RBP),β2-MG were detected in the blood biochemistry automatic analyzer. These laboratory markers were inspected before treatment and at the 4th,8th and 12th week after treatment. Results Ninety-six patients in the experiment group and 95 patients in the control group were effectively included in the end. Before treatment,there were no statistic significant differences in urine mALB,mALB/UCr,β2-MG,α1-MG and blood ET-1,NO,TXB2, 6-keto-PGF1α between two groups(all P>0.05). Along with the prolongation of treatment,urine mALB,mALB/UCr,β2-MG,α1-MG and ET-1,TXB2 were significantly reduced,while NO,6-keto-PGF1α were significantly raised in the two groups after treatment,and the above changes in the experimental group were more obvious. There were statistic significant differences of mALB,mALB/UCr,β2-MG,α1-MG and TXB2,6-keto-PGF1αbetween two groups at the 12th week after treatment〔mALB(mg/L):36.6±9.2 vs. 78.6±16.5,mALB/UCr(mg/mmol):3.90±1.97 vs. 9.70±2.90,β2-MG(mg/L):0.25±0.10 vs. 0.40±0.12,α1-MG(mg/L):8.40±2.26 vs. 12.50±3.21,TXB2 (ng/L):75.8±18.7 vs. 94.7±21.7,6-keto-PGF1α(ng/L):73.4±15.2 vs. 65.2±11.5,P<0.05 or P<0.01〕. But there were no statistic significant differences of ET-1 and NO between experimental group and control group at the same time-points〔ET-1(ng/L):57.6±6.9 vs. 59.1±6.2,NO(μmol/L):68.9±11.6 vs. 65.4±10.7,both P>0.05〕. In each of the two groups,the comparisons of the levels of SCr,BUN before and after treatment,there was no statistical significant difference at any time point;the same comparisons between the two groups,there was also no statistic significant difference before treatment and at each of the same time-point after treatment(all P>0.05). The levels of Cys-C,RBP andβ2-MG of the control group after treatment had the tendency of decreasing,but no statistic significant differences were found(all P>0.05). The levels of Cys-C,RBP,β2-MG of the experimental group at the 12th week after treatment were significantly lower than those before treatment〔Cys-C(mg/L):0.72±0.07 vs. 0.89±0.12,RBP (mg/L):53.0±14.2 vs. 66.1±16.5,β2-MG(mg/L):1.86±0.71 vs. 2.79±0.82,all P<0.05〕. Conclusions Qizhi Jiangtang capsule can significantly reduce the levels of urine mALB and mALB/UCr of patients with stageⅢDN and stabilize their renal functions;its therapeutic effect is better then that of valsartan. Its mechanisms are related to the reduction of ET-1,elevation of NO,maintenance of dynamic equilibrium of thromboxane A2/prostacycline(TXA2/PGI2) and protection of vascular endothelial cells.

Prostate cancer is one of the common malignant tumors of male urogenital system, and the incidence of prostate cancer in China has increased significantly in the past decade. At present, endocrine therapy based on androgen blockade is the main method of clinical treatment except radical surgery and radiotherapy/chemotherapy for prostate cancer. However, the clinical benefit can only be obtained in the early stage of treatment, and nearly 90% of patients will develop to the castration resistance, and among them, nearly 90% of patients will have bone metastasis. The quality of life decreases sharply with the progression of disease for patients. In addition to the androgen signal pathway, studies have shown that many other oncogenic signal pathways have involved in the development of castration resistance, including classic cancer signaling pathways, immune and inflammatory signaling pathways, etc. Understanding the mechanism of androgen independent signal pathway in the formation of castration resistance will help to understand the off-target effect of androgen blocking therapy and introduce new treatment targets or strategies to get rid of the "no drug available" dilemma for clinical treatment of castration resistance.

Multi-target drugs attract increasing attentions for the therapy of complicated neurodegenerative diseases. In this study, a computer-assisted strategy was applied to search for multi-target compounds by the pharmacophore matching. This strategy has been successfully used to design dual-target inhibitor models against both the acetylcholinesterase (AChE) and poly (ADP-ribose) polymerase-1 (PARP-1). Based on two pharmacophore models matching and physicochemical properties filtering, one hit was identified which could inhibit AChE with IC50 value of (0.337 +/- 0.052) micromol x L(-1) and PARP-1 by 24.6% at 1 micromol x L(-1).

Objective To investigate the prevalence and influencing factors of dysmenorrhea among female college students in Changchun city, so as to provide scientific basis for health promotion and effective preventive measurement. Methods Non-randomized convenience sampling and face to face interview were used to collect information from female college students aged between 17 and 25 years in 14 universities in Changchun. Chi-square test and logistic regression model were used to analyze influencing factors of dysmenorrhea. Results The average age of 1 071 subjects was 21.21 ± 1.83 years. The prevalence of dysmenorrhea was 86.55%. The proportion of mild dysmenorrhea among the subjects was 62.56%, followed by 33.01% with moderate dysmenorrhea and 4.43% with severe dysmenorrhea; 80.76% of subjects paid attention to keep warm in the daily life. Normal BMI, sleeping before 23 o'clock or between 23 to 24 o'clock, taking exercise frequently or everyday might be the protective factors of dysmenorrhea, and the OR values (95% CI) were respectively as 0.60 (0.37-0.97), 0.56 (0.37-0.84), 0.42 (0.22-0.78) and 0.63(0.42-0.97). Tension and the family history of dysmenorrhea might be the risk factors, and the OR values (95%CI) were respectively 1.63 (1.10-2.41), 4.84 (2.80-8.35). Conclusion The prevalence of dysmenorrhea is high among female college students. Lacking exercise, BMI less than 18.5 kg/m2, staying up late, tension and the family history of dysmenorrhea may be the influencing factors of dysmenorrhea among female college students.

OBJECTIVETo observe the efficacy and safety of Qizhi Jiangtang Capsule (QJC) in treating stage 3b diabetic kidney disease (DKD) patients with macroalbuminuria.

METHODSPatients who conformed to the diagnostic criteria of stage 3b DKD were randomly assigned to two groups according to random digital table, the experiment group and the control group, 84 in each group. All patients received a two-week elution period, and then were treated with basic Western therapy. Patients in the experiment group took QJC, 5 pills per time, 3 times a day, while those in the control group took Valsartan Capsule 160 mg each time, once daily. The observation period of follow-ups was limited within 6 months, and the time points were set as the baseline, 1st month, 3rd month, and 6th month. Systolic blood pressure (SBP), diastolic blood pressure (DBS), 24 h urine protein quantitative (24 h UPQ), plasma albumin (ALB), and serum creatinine (SCr) were detected and recorded, and estimated glomerular filtration rate (eGFR) was calculated. The occurrence of hypoglycemic reaction, coagulation disorder, gastrointestinal tract reaction, allergy, hyperkalemia, doubling of creatinine, and overall adverse events were observed and recorded at same time.

RESULTSFinally 81 patients in the experiment group and 80 patients in the control group were effectively included. Compared with the baseline level, SBP and DBS obviously decreased in the control group at month 1 of treatment (P < 0.05), and more significantly decreased at month 6 of treatment (P < 0.01). SBP at month 1, 3, and 6 of follow-ups; DBS at month 6 of follow-ups was lower in the control group than in the experiment group (P < 0.05). At month 1, 3, and 6 of follow-ups, 24 h UPQ of the experiment group was significantly lower than the baseline level (P < 0.01). It was also significantly lower than the level of the control group at the same time point (P < 0.05). There was no significant difference in 24 h UPQ at month 1, 3, and 6 of follow-ups between the control group and the baseline level (P > 0.05). ALB of the experiment group showed an increasing trend. It was significantly higher than the baseline level at month 6 (P < 0.05), which was also higher than that of the control group at same period (P < 0.05). There was no significant difference in the ALB level in the control group (P > 0.05). SCr of two groups showed an increasing trend. SCr of the experiment group was significantly higher at month 1, 3, and 6 follow-ups than the baseline level (P < 0.05). But the increment of SCr was higher in the control group than in the experimental group, and obviously higher than the baseline levels (P < 0.05). eGFR of both groups showed a decreasing trend. The decrement was higher in the control group than in the experimental group (P < 0.05). The proportion of progression of renal functions at month 1, 3, and 6 of follow-ups in the experimental group was 0.0% (0 case), 9.55% (8 cases), and 21.4% (18 cases), while they were 8.3% (7 cases), 21.4% (18 cases), and 40.5% (34 cases) in the control group. There was no statistical difference in the proportion of progression of renal functions between the two groups at month 3 and 6 of follow-ups (P < 0.05). There was no statistical difference in the incidence of adverse reactions between two groups (P > 0.05).

CONCLUSIONQJC could effectively reduce urinary protein of patients with stage 3b DKD, and delay the progression of renal functions.

Objective:To study the effect of tannins from Pericarpium Granati on hepatic microsomal enzyme in rats. Methods:Thirty Wistar rats were randomly divided into five groups:the blank control group, high, medium and low dose groups of tannins from Pericarpium Granati, the positive control group of phenobarbital sodium. The blank control group was given physiological saline. The three different doses groups were respectively given tannins from Pericarpium Granati orally at the dose of 150,100 and 75 mg·kg-1 · d-1 for 7 days. The positive control group was given phenobarbital sodium 80 mg·kg-1 ·d-1 with intramuscular injection for 5 days. At the end of the experiment, the activity ofⅠandⅡphase metabolic enzymes in liver microsomes of each group was determined by UV. Results:Compared with the blank control group, the high, medium and low dose groups of tannins from Pericarpium Granati could sig-nificantly decrease the content of CYP 450 and CYPb5, and inhabit the activity of ADM (P<0. 01);the high and medium dose group could significantly inhibit ERD enzyme activity (P<0. 01);the high dose group could significantly reduce GST enzyme activity (P<0. 01). Conclusion:Tannins from Pericarpium Granati has notably inhibitory effect on hepatic microsomal enzyme in rats, which can reduce the expression of CYP3A and CYP2E1 in a dose-dependent manner.

Objective To evaluate the effect on salvage treatment of sudden deafness with comprehensive Chinese medicine therapy. Methods Fifty-three sudden deafness patients failing in conventional western medicine treatment were given comprehensive Chinese medicine therapy, and the salvage treatment followed by oral use of Chinese medicine, intravenous injection of Chinese patent medicine, acupoint injection, ear acupoint plastering, acupoint application, acupuncture, sound healing, and massage. The therapeutic effect and the relief of major accompanying symptoms were evaluated after treatment, and the relationship of disease course with clinical efficacy was also investigated. Results (1) After treatment, 4 cases were cured, 9 were markedly effective, 13 were effective, 27 were ineffective, and the total effective rate was 49.06%. (2) Except for the 2 excluded cases, the major accompanying symptoms such as tinnitus, auricular distress, and vertigo were relieved to various degrees in other cases. ( 3) Twenty-two patients had a course of disease within 14 days, and the total effective rate for them was 72.73%. A total effective rate of 32.26% was achieved in 31 cases with disease course over 14 days. It is indicated that the therapeutic effect for patients with a disease course less than 14 days was superior to that with a disease course over 14 days (P<0.01). Conclusion Comprehensive Chinese medicine therapy exerts inspiring therapeutic effect on salvage treatment of sudden deafness, and earlier intervention results into better effect.

BACKGROUND: For treatment of femoral neck fracture, all therapies with the exception of joint replacement encounter the problems including slow healing, poor prognosis, various complications, and unable to bear weight for long time. Fracture hip supporting joint (FHSJ) is a novel unlimited hip support implement that possesses the double functions of fracture fixation and joint supporting and can be used to prevent and treat the complications of femoral neck fracture in young people.OBJECTIVE: To investigate the mechanical effects of FHSJ on treatment of femoral neck fracture.METHODS: Three types of two-dimensional finite element models were constructed by AutoCAD: normal hip (group A), femoral neck fracture fixed with two screws (group B), and femoral neck fracture fixed with two screws and FHSJ (group C). The grids of two-dimensional four nodal point elements were divided by ANSYS (PLANE82). Under the identical condition, the calculations were performed respectively.RESULTS AND CONCLUSION: The stress peak value of femoral head weight-bearing zone was 1.029 and 1.63 MPa in group A and group B, respectively, and that in the group C was 0.1-0.4 MPa. The stress peak value of the screws was 37.186 and 7.474 MPa in the group B and group C, respectively. These results indicate that FHSJ installation based on fixation of multiple screws could promote the recovery of femoral head and neck, which exhibits promising prospects in treatment of femoral neck fracture in young people.

To explain biological function of protein CCL15 in HCC cell lines. The different expression level of CCL15 among HCC cell lines was validated by RT-PCR and Western blot. The expression recombinant plasmid of siRNA-CCL15 was constructed successfully and transfected into high metastasis cell lines HCCML3 to observe the alteration of biological function of HCCML3. The overexpression of CCL15 in high metastasis HCC cell lines was confirmed by validation tests. After transfected with siRNA-CCL15, the average amounts of invaded cells in cell invasion assay were 657.9 (HCCML3) and 148.4(HCCML3-siCCL15) (t=19.34, P less than 0.05). And in the scratch assay, the migrating distance were (0.35+/-0.02) mm (HCCML3) and (0.82+/-0.03)mm (HCCML3-siCCL15) (t=15.67, P less than 0.05). The expression of MMP-9 in HCCML3 was higher than HCCML3-siCCL15 through Western blot. Some biological properties (migration, invasion, MMP-9) of HCCML3 transfected with siRNA-CCL15 were decreased. The results suggest CCL15 might play an important role in HCC cell invasion and metastasis through two paths of MMPs regulation and invasion potential strengthening.
