OBJECTIVETo observe the effect of Xiaoyao Nose Drops (XYND) in stopping episode of migraine.

METHODSAdopted was the randomized double-blinded placebo-controled method, with the 126 patients equally assigned to two groups, the treated group treated with XYND and the control group with placebo, and the therapeutic course was 30 days for all. The clinical total effective rate and effect in alleviating headache were observed. And hemorrheological parameters as well as the blood flow of the anterior cerebral artery (ACA), median cerebral artery (MCA) and posterior cerebral artery (PCA) were measured before and after treatment.

RESULTSThe clinical total effective rate and headache alleviating rate in the treated group were 93.33% and 96.67% respectively, while those in the control group were 18.33% and 20.00% respectively, and comparison between the two groups showed significant difference (all P < 0.01). The blood viscosity (high, middle and low shear), plasma viscosity and fibrinogen got lowered significantly in the treated group after treatment, showing significant difference in comparison either with those before treatment or with those in the control group after treatment (P < 0.05 or P < 0.01). The velocity of blood flow in all cerebral arteries lowered significantly, also showing significant difference in comparison either with those before treatment or with those in the control group after treatment (P < 0.05 or P < 0.01).

CONCLUSIONXYND is effective in stopping the headache of patients with migraine, and worth applying in clinical practice.

OBJECTIVETo investigate the effect of HS3ST3B1 on hepatitis B virus (HBV) replication.

METHODSHepG2 cells were classified into 7 groups according to the plasmids transfected: (1) Blank group, no plasmid transfected; 2. Positive control, transfected with pCH9-HBV which permits HBV replication; (3) Negative control, transfected with pCH9-HBV + pcDNA3.1 + pTZU6+1; (4) Treatment A, transfected with pCH9-HBV + pCDNA3.1-HS3ST3B1 + pTZU6+1; (5) Interference A, transfected with pCH9-HBV + pCDNA3.1-HS3ST3B1 + psh1126 (a plasmid to interfere HS3ST3B1 expression); (6) Treatment B, transfected with pCH9-HBV + pTZU6+1; (7) Interference B, transfected with pCH9-HBV + psh1126. The levels of HBV DNA were detected in the above groups by Southern blotting. HBV total RNA of Negative control, Treatment A and Interference A were quantified by Real-time PCR to determine the influence of HS3ST3B1 over-expression on the HBV RNA transcription. The activity of the four HBV promoters [core promoter (cp), x promoter(xp), surface antigen promoter1(sp1), surface antigen promoter2 (sp2)] were assayed by Dual-Luciferase Reporter Assay System. The data was analyzed using one way ANOVA, with P < 0.05 indicating statistically meaningful difference.

RESULTSouthern blot data revealed the level of HBV DNA in Treatment A and Interference A accounted for 10% +/- 2% and 31% +/- 4% of that in control. Compared with control, a statistical difference existed between Treatment A and Control, with F value equalling to 20.8 and P value equalling to 0.034 respectively. A statistical difference also existed between Interfere A and Treatment A, with F value equalling to 24.9 and P value equalling to 0.021 respectively. The level of HBV DNA in Experiment B was raised by 130% +/- 11% as compared to that in Interference B, and the levels of HBV DNA showed a dose-dependent decrease when H7 cells were transfected with 0.5, 1.0, 1.5 microg pCDNA3.1-HS3ST3B1 respectively. Statistical differences existed between control and H7 transfected with different dose of pCDNA3.1-HS3ST3B1, with F values equalling to 22.7, 20.3, 26.5 and P values equalling to 0.029, 0.041 and 0.015 respectively. Real-time PCR revealed that the HBV total RNA in Treatment A accounted for 17.0% +/- 2.7% of that in control and there was a statistical difference between Treatment A and control, with F value equalling to 25.6 and P value equalling to 0.018. In addition, HBV DNA in Interference A was restored to 74.0% +/- 3.9% of that in control, and there was also a statistical difference between Treatment A and Interference A, with F value equalling to 21.3 and P value equalling to 0.032. However, the down regulation of HBV total RNA had nothing to do with HBV promoters activity.

CONCLUSIONHS3ST3B1 can inhibit HBV replication and reduce the level of HBV total RNA, but the downregulation of HBV total RNA may not be the result of direct interaction of HS3ST3B1 and HBV promoters.

OBJECTIVETo study the effects of Compound Fujian Tablet (FJT)on the neurotization in the cerebral infarction rats and to explore its mechanisms for promoting the motor skills.

METHODSTotally 90 Wistar rats were randomly divided into the drug group, the model group, and the sham-operation group, 30 in each group. The rat model of middle cerebral artery occlusion (MCAO) was successfully established by electrocoagulation. Six hours after successful modeling, the rats of the drug group were orally administered with 9 g/kg FJT water solution, and the other groups were orally administered with equal volume of normal saline, once a day for two weeks. The motor skills of rats were examined by beam walking test. The expressions of nestin, polysialic acid neural cell adhesion molecule (PSA-NCAM), microtubule-associated protein 2 (MAP-2), growth-associated protein (GAP-43), and synaptophysin (Syn) in the brain tissue around the infarction were observed by in immunohistochemical assay. The mean staining gray or the optical density value were detected.

RESULTSThe 86 rats were recruited in the result analysis. After two weeks of administration, the neural function scoring was obviously higher in the drug group than in the model group with statistical difference (P < 0.01). The expressions of nestin, PSA-NCAM, MAP-2, GAP-43, and Syn in the brain tissue around the infarction were more obviously enhanced in the drug group than in the model group, showing statistical difference (P < 0.01).

CONCLUSIONFJT can promote neurotization and improve the motor skill recovery after cerebral infarction.

OBJECTIVETo compare the clinical results of early and delayed intramedullary nailing and locked plating for the treatment of multi-segments tibial fractures of type AO/ASIF-42C2.

METHODSBetween January 2010 and January 2013,45 patients with multi-segments closed tibial fractures of AO/ASIF-42C2 were treated by early primary intramedullary nailing and locked plating in 20 cases as early group and delayed in 25 cases as delayed group. In early group,20 cases included 13 males and 7 females with an average age of (37.9±14.3) years old ranging from 20 to 56 years;according to soft tissue injury Tscherne classification, 8 fractures were frade I,12 were grade II. In delayed group, 25 cases included 17 males and 8 females with an average age of (38.7±17.2) years old ranging from 24 to 55 years,4 fractures were grade I ,19 were grade II ,2 were grade III. The operative time, blood loss, hospital stay,fracture healing time and complications were recorded. At final follow-up, the Johner-Wruhs score were used to evaluate functional efficacy, and the posterior-anterior and lateral X-ray to evaluate fracture reduction and alignment.

RESULTSAll the patients were followed up for (12.5±2.5) months in early group and (13.2±2.8) months in delayed group (P>0.05). No wounds infections were happened. At the last follow-up, the mean range of knee joint was 10°-0°-120°. According to Johner-Wruhs scoring,there were 15 cases in excellent,3 in good,fair in 2 in early group; 21 in excellent,2 in good,2 in fair. The average operative time,blood loss had no significant differences between two groups (P>0.05), but hospital stay in early group was significantly shorter than those in delayed group(P<0.05). Average fracture healing time of early group and delayed group were (5.3±2.6) months and (6.0±2.9) months, respectively (P>0.05).

CONCLUSIONFor multi-segments tibial fractures of type AO/ASIF-42C2 with preoperative minor soft tissue injuries lighter of Tscherne grade I or II, early primary intramedullary nailing and locked plating does not significantly increase the postoperative incidence of soft tissue complications for patients. The early and delayed primary intramedullary nailing and locked plating for treatment of AO/ASIF-42C2 proximal third tibial fractures can get similar curative effect.

OBJECTIVETo explore the effect of the phosphoinositide 3-kinase/protein kinase B (PI3K/PKB or PI3K/AKT) signaling pathway inhibitor on benign prostate hyperplasia (BPH) and its mechanism.

METHODSForty-eight SD male adult rats aged 12 weeks were equally randomized to 4 groups: sham operation control, BPH model, 50 mg LY294002 and 100 mg LY294002. The BPH models were made by muscular injection of testosterone propionate at 10 mg/kg/d for 30 days following castration. The LY294002 groups were treated with the PI3K/AKT signaling pathway inhibitor LY294002 at 50 and 100 mg/kg every other day for 30 days. The prostates of the rats were weighed and the structural changes of the prostatic histiocytes observed under the light microscope. The expressions of Ki-67, anti-apoptotic Bcl-2 and apoptotic Bax were detected by immunohistochemistry, and the apoptosis of prostatic cells determined by terminal de-oxynucleotidyl transferase-mediated dUTP nick end labeling.

RESULTSThe prostate wet weight and prostatic index were (551 +/- 10.8) mg and 1.61 +/- 0.05 in the sham operation group, (687 +/- 13.8) mg and 2.15 +/- 0.12 in the BPH model group, (623 +/- 23.5) mg and 1.95 +/- 0.11 in the LY294002 50 mg group (P < 0.05 versus the BPH models) and (561 +/- 12.6) mg and 1.71 +/- 0.18 in the LY294002 100 mg group (P < 0.01 versus the BPH models). The expressions of apoptotic Bax and anti-apoptotic Bcl-2 were 16.7% and 16.7% in the sham operation group, 16.7% and 58.3% in the BPH model group, 33.3% and 33.3% in the LY294002 50 mg group (P < 0.05 versus the BPH models), and 50.0% and 25.0% in the LY294002 100 mg group (P < 0.01 versus the BPH models). The proliferative and apoptotic indexes were 14.2 +/- 6.4 and 6.5 +/- 1.8 in the epithelial and 7.6 +/- 2.6 and 2.5 +/- 0.3 in the interstitial tissue of the sham operation group, 50.9 +/- 12.8 and 2.7 +/- 1.4 in the epithelial and 16.5 +/- 5.7 and 1.3 +/- 0.8 in the interstitial tissue of the BPH models, 32.0 +/- 13.8 and 6.2 +/- 2.5 in the epithelial and 12.1 +/- 3.8 and 1.6 +/- 1.1 in the interstitial tissue of the LY294002 50 mg group (P < 0.05 versus the BPH models), and 17.8 +/- 14.7 and 7.4 +/- 3.6 in the epithelial and 9.5 +/- 3.4 and 2.2 +/- 1.3 in the interstitial tissue of the LY294002 100 mg group (P < 0.01 versus the BPH models).

CONCLUSIONThe increased proliferation and decreased apoptosis of prostatic cells in the BPH animal models might be involved in the development and progression of BPH. The PI3K/AKT signaling pathway plays an important role in the development of BPH, which could be inhibited by blocking the PI3K/AKT signaling pathway.

OBJECTIVETo observe the efficacy of Qilin Pills in the treatment of oligoasthenospermia.

METHODSWe conducted a multi-centered open controlled clinical trial by including 220 oligoasthenospermia patients in a trial group and another 110 as controls. The patients in the trial group were treated with Qilin Pills at the dose of 6 g tid, and the controls given Wuziyanzong Pills at 6 g bid, both for a course of 12 weeks. Then we evaluated the clinical effects of Qilin Pills with sperm concentration, the numbers of grade a and grade a + b sperm, and sperm motility as the primary, and the pregnancy rate of the patients'spouses as the secondary therapeutic indexes.

RESULTSA total of 310 patients accomplished the clinical trial, 208 in the trial and 102 in the control group. Compared with the baseline, significant improvement was observed in the semen parameters after 4, 8 and 12 weeks of treatment in both the trial and control groups except sperm density and the number of grade a sperm in the control after 4 weeks (P < 0.01), and the improvement was even more significant in all the semen parameters at the same time points in the trial than in the control group (P < 0.01).

CONCLUSIONQilin Pills can evidently improve the seminal quality of oligoasthenospermia patients with no obvious adverse events.

OBJECTIVETo evaluate the efficacy and safty of the humanized anti-epidermal factor receptor monoclonal antibody h-R3 in combination with radiotherapy for locoregionally advanced nasopharyngeal carcinoma.

METHODSTotally, 137 patients from 7 medical center around China were randomly divided into combined therapy group or control group. There was no difference in Karnofsky performance score between two groups. All patients in both groups received radical conventionally fractionated radiotherapy to the total dose of D(T) 70-76 Gy. For the combined therapy group, h-R3 was added at a dose of 100 mg i.v. weekly for 8 weeks started at the beginning of radiotherapy.

RESULTSOf the 137 eligilbe patients, 70 were in the combined therapy group treated by h-R3 plus radiotherapy and 67 in the control group by radiotherapy alone. The intent-to-treat (ITT) population consisted of 130 patients, while the per-protocol (PP) population was composed of 126 patients. The efficacy was assessed respectively at three point of time: the end of treatment, the 5th- and 17th-week after treatment. The complete response (CR) of the combined therapy group was significantly higher than that of the control group in both ITT and PP (ITT: 65.63%, 87.50%, 90.63% versus 27.27%, 42.42%, 51.52%; PP: 67.21%, 90.16%, 93.44% versus 27.69%, 43.08%, 52.31%; P < 0.05, respectively). The most common h-R3-related adverse reactions were fever (4.3%), hypotension (2.9%), nausea (1.4%), dizziness (2.9%) and rash (1.4%), which could be reversible if treated properly. Radiotherapy combined with 100 mg h-R3 i. v. weekly was tolerable and did not aggravate the side effects of radiation. The quality of life in the combined therapy group was comparable to that in the control group.

CONCLUSIONThis phase 1 multicenter clinical trial shows that h-R3 in combination with radiotherapy is effective and well-tolerated for the treatment of locoregionally advanced nasopharyngeal carcinoma.
