OBJECTIVETo observe the effects of electroacupuncture at Neiguan (PC 6) and Jianshi (PC 5) com- bined with granisetron on nausea and vomiting as well as serum levels of 5-hydroxy tryptamine (5-HT) and dopamine (DA) in chemotherapy patients.

METHODSSeventy-two chemotherapy patients who met the inclusive criteria were randomly divided into an observation group (38 cases) and a control group (34 cases). The patients in the observation group were treated with electroacupuncture at Neiguan (PC 6) and Jianshi (PC 5) combined with granisetron injection; the patients in the control group were treated with electroacupuncture at sham-point 1 and sham- point 2, and the rest treatment was identical to the observation group. After 3-day treatment, the clinical indices including times of vomiting and severity of nausea, etc. were observed in the two groups.

RESULTS(1) At the acute stage within 24 h, the times of vomiting in the two groups were not significantly different (P>0.05); at the delay stage, the severity of nausea was significantly higher in the control group (P<0.05). (2) As for the comprehensive efficacy and rate of complete control, there was no obvious difference between the two groups at the acute stage (P>0.05); while in the delay stage, the rate of complete control in the observation group was superior to that in the control group (P<0.01). (3) Compared before and after the treatment, serum levels of 5-HT and DA were evidently reduced in the observation group (both P<0.05), while those in the control group were not significantly changed after treatment (both P>0.05).

CONCLUSIONElectroacupuncture at Neiguan (PC 6) and Jianshi (PC 5) combined with granisetron could obviously relieve the nausea in chemotherapy patients at the delay stage. The effect mechanism is possibly related to reducing the content of 5-HIT nndl nA

BACKGROUND: Hydrogen sulfide signaling has been proved to promote distraction osteogenesis; however,the underlying mechanism remains unclear.OBJECTIVE: To evaluate the relationship between hydrogen sulfide and hypoxia-inducible factor-1α (HIF-1α)during the osteogenesis of rat bone marrow mesenchymal cells under tensile stress.METHODS: 2000 μ strain was loaded on the in vitro cultured rat bone marrow mesenchymal cells by a four-point bending apparatus, and hydrogen sulfide donor or HIF-1α inhibitor was adopted in the tensile unit. Subsequently, the levels of osteogenic markers were detected.RESULTS AND CONCLUSION: Exogenous hydrogen sulfide signaling could promote the osteogenesis of rat bone marrow mesenchymal cells under tensile stress. However, this promotion was obviously eliminated when the endogenous HIF-1α expression was inhibited.These results show that hydrogen sulfide signaling system promotes the osteogenesis of rat bone marrow mesenchymal cells under tensile stress probably through HIF-1α.

Objective To investigate the clinical value of 125I particle implantation brachytherapy combined with intermittent hormonal therapy for treating clinical moderate and high risk non-metastatic prostate cancer.Methods A prospective study was proceeded and 100 cases with moderate and high risk (cT≥T2b,Gleason score ≥ 7,pre-biopsy PSA ≥ 10 ng/ml)non-metastatic prostate cancer were included.The selected patients were divided into two group.In the study group,patients were treated with 125I particle implantation combined with intermittent hormonal therapy.In the control group,patients were treated with only intermittent hormonal therapy.Hormonal therapy was maximal androgen blockage for two groups,including bicalutamide 50 mg oral every day and Leuprorelin 3.75 mg subcutaneous injection every 28 days.There were 50 cases in each group and clinical trial agreements were signed.During follow-up,PSA were tested every month.Chest X-ray and whole-body hone scanning were checked every 6 months.Hormonal therapy was stopped when patient's PSA level fell to 0.2 ng/ml,and keep stabilized for 3 months.When PSA level elevated for 3 times continuously and over 1 ng/ml,hormonal therapy was initiated again.The IPSS scores were documented before treatment and every 3 months after treatment.Adverse reactions of urinary tract and rectum were assessed every 3 months after 125I particle implantation in study group.The ratio of the first time to stop hormonal therapy,the time duration of first hormonal therapy and stable phase,re-hormonal therapy free survival rate,bone metastasis free survival rate,castration resistance prostate cancer(CRPC) free survival rate,cancer-specific free survival rate and overall survival rate were compared.Results The 100 cases in this study were followed up for 24-40 months,with an average time of 31.6 months.In study group,the PSA level in all cases descended to the level of stopping hormonal therapy.The time duration of hormone therapy ranged from 4 to 12 months,with an average time of 6.3 months.21 (42％) cases had a PSA elevation again to restart hormonal therapy.In control group,the PSA level in 47 cases descended to the level of stopping hormonal therapy.The time duration of hormone therapy ranged from 5 to 15 months,with an average time of 7.2 months.34 (68％) cases had a PSA elevation again to restart hormonal therapy.There was no significant difference in percentage of cases of stopping hormone therapy and in time duration of hormonal therapy for the first cycle.Instead,there were significant differences in stable phase after first cycle hormonal therapy between two groups (27.2 months vs.17.7 months;P ＜ 0.001).When analyzed by Kaplan-Meier survival curve,there was no significant difference in cancer-specific survival rate and overall survival rate.There were significant differences in Re-hormonal therapy free survival (P =0.002),bone metastasis free survival (P =0.04) and CRPC free survival(P =0.005).Conclusions Compared with intermittent hormonal therapy alone,125I particle implantation brachytherapy combined with intermittent hormonal therapy could prolong the hormonal sensitive time in moderate and high risk nonmetastatic prostate cancer patients and control the progress of the prostate cancer.

Objective To observe the effect of Xuebijing injection on the expression of tumor necrosis factor-alpha (TNF-α) and high mobility group box-1 protein (HMGB-1) in rat peritoneal mesothelial cells (PMCs) induced by lipopolysaccharide (LPS). Methods PMCs were isolated from rat colic omentum and the 3rd generation cells were used in the experiment. PMCs were incubated with LPS at different concentrations (1,10,100 mg/L);with LPS (10 mg/L) for 2, 6, 12, 18, 21, 24, 36 h;with Xuebijing injection at different concentrations (2,10,20 g/L) after incubation with LPS (10 mg/L) for 2 h. PMCs in the control group were incubated with medium. HMGB-1 mRNA was detected by RT-PCR. TNF-α and HMGB-1 protein in supernatants was detected by ELISA. Results Compared to the control group, the expression of HMGB-1 mRNA and protein was significantly increased in groups stimulated by LPS in a time- and dose-dependent manner (all P<0.05);the expression of TNF-α was increased in the groups stimulated by LPS in a dose-dependent manner (P<0.05). In the groups stimulated by LPS (10 mg/L), the expression of TNF-α appeared double hump within 36 hours. Compared to LPS (10 mg/L) group, Xuebijing injection significantly inhibited the expression of HMGB-1 and TNF-α (all P<0.05 ) in a dose-dependent manner. Conclusions HMGB-1 as a late mediator of inflammatory responses may play a role in the pathogenesis of peritoneal dialysis related peritonitis. Xuebijing injection can reduce peritoneal inflammatory impairment by inhibiting the up-regulation of TNF-α and HMGB-1 induced by LPS.

ObjectiveTo compare the clinical characteristic and postoperative histopathological parameters in different prostate size and to assess the effect of prostate volume on histopathological outcomes in patients after laparoscopic radical prostatectomy. MethodsTwo hundred and sixteen patients from 2006 to 2011 who were proved prostatic carcinoma by biopsy and performed laparoscopic radical prostatectomy wewe retrospectively evaluated.All patients were divided into the small group ( ＜ 30 ml,103 cases),intermediate group(30 -60 ml,71 cases) and large group ( ＞60 ml,42 cases) according to prostate volume.Clinical variables included age,body mass index (BMI),preoperative PSA level,prostate volume,percentage of positive needles,clinical stage,and biopsy Gleason score (GS).Histopathological parameters included pathological GS,upgrading or not compared to biopsy GS,pathological stage and surgical margins status.Preoperative clinical variables and postoperative histopatholgogical parameters were compared among the 3 prostate groups. ResultsPatients with smaller prostates had lower PSA levels than those with intermediate and larger prostates (P =0.000).They also had worse histopathological outcomes such as pathological GS ( P =0.034 ),upgrading of GS ( P =0.037 ),and pathological stage ( P =0.025 ).35.0％ of patients in smaller prostate group had a positive surgical margin compare to 33.8％ and 19.0％ in intermediate and larger prostate groups,but there was no significant difference (P =0.152).ConclusionMen with smaller prostate may have more high-grade cancer and more advanced disease after laparoscopic radical prostatectomy.
