To introduce the international registration condition of acupuncture clinical research. With the examples of World Health Organization International Clinical Trials Registry Platform and the U. S. National Institutes of Health Clinical Registration Platform, the registration method and current condition of acupuncture clinical trials in international clinical trials registration platform were analyzed. The results indicate that the number of acupuncture clinical trials registration is gradually increased and the registration number from China is on the rise as well. But most domestic acupuncture clinical researches haven't been registered arid the researchers' valuing degree for clinical trials registration and methodology research needs to be improved.

OBJECTIVETo study whether acupressure could relieve urinary retention after radical hysterectomy in cervical cancer patients.

METHODSA randomized controlled prospective double-blinded trial was carried out in 107 urinary retention patients undergoing grade III radical hysterectomy. They were assigned to Group A (positive acupoints, 40 cases), Group B (negative acupoints, 32 cases) , and Group C (with no acupoints, 35 cases). All patients received protective 115 000 potassium permanganate sitz bath, 15 - 20 min each time, 3 times per day. Patients in Group A received acupressure at positive points [liniao point and Qihai (RN6)] combined points by syndrome typing [Guanyuan (RN4) , Zhongji (RN3) , Shenshu (BL23) , Zusanli (ST36), Sanyinjiao (SP6), and Taixi (K13)]. Patients in Group B received negative acupressure at sham-acupoints (for adjusting gastrointestinal functions). Patients in Group C only received conventional sitz bath. All medication was performed 3 times per day, 7 days as one therapeutic course, 21 days in total. The residual urine volume was detected. The recovery time for bladder function was recorded. The average residual urine volume was also recorded at day 7, 14, and 21.

RESULTSCompared with Group B and C, the time for ureter retention was shortened for mild and severe CKD patients in Group A (P <0. 01). The residual urine volume was also lessened for mild and severe CKD patients in Group A at day 7, 14, and 21 (P <0.01).

CONCLUSIONCervical cancer patients could relieve urinary retention by self-acupressure after radical hysterectomy.

OBJECTIVETo evaluate the clinical outcomes of percutaneous intervertebral foramina endoscopic lumbar discectomy for elder patients with lumbar spinal stenosis syndrome.

METHODSFrom July 2006 to July 2011, 60 elder patients with lumbar spinal stenosis syndrome were treated with surgical operation, including 32 males and 28 females with an average age of (66.7 +/- 2.5) years old ranging from 72 to 83 years. These patients were divided into the traditional surgery group and percutaneous intervertebral foramina endoscopic discectomy groups (PTED group), 30 cases in each group. The index of the preoperative and postoperative, operative incision visual analogue scale (VAS) of two groups were compared. The Oswestry disability index (ODI) of two groups at 6, 24 months of the follow-up were also evaluated on activity of daily living.

RESULTSThe average operative time, the average blood loss, the number of cases using analgesic drug, hospitalization time of PTED group were better than those of the traditional surgery group (P < 0.05). The improvement of incision VAS in PTED group was better than that in the traditional surgery group (P < 0.05). All patients were followed up for 24 months at least. The ODI at 1, 24 month after operation were better than that of preoperative in two group respectively (P < 0.05), but the improvement of PTED group was better than that of the traditional surgery group (P < 0.05).

CONCLUSIONPTED has the advantages of smaller incision, less bleeding, less postoperative stay and hospitalization time, tissue trauma and quicker recovery. It is a safe and efficacious minimally invasive surgical technique for elder patients with lumbar spinal stenosis syndrome.

Objective To analyze the clinicopathological characteristics and the prognostic survival factors of young patients who have undergone hepatectomy for primary hepatic carcinoma.Methods Clinicopathological da-ta and treatment outcomes in 79 young (≤40 years old)and 67 elderly (≥65 years old)patients who underwent hep-atectomy for primary hepatic carcinoma between 2008 and 2012 were retrospectively collected and compared using various parameters.Then the survival rate and prognostic factors of the younger patients were analyzed using Kap-lan-Meier and COX multivariate proportional hazards model.Results The positive rate of HBs-antigen and alpha-fetoprotein level were significantly higher in the younger patients than in the elderly patients (P<0.05).However, the positive rate of Anti-HCV-Ab was markedly lower in the younger patients (P<0 .0 5 ).The two groups did not significantly differ in gender,clinical symptoms,intraoperative parameters or pathological features (P>0.05).The overall survival rate was similar between the two groups.COX multivariate proportional hazards model analysis showed that the independent prognostic factors of overall survival were pre-operative albumin level <3 5 g/L and maximum tumor diameter ≥5 cm.Conclusion Hepatectomy is a safe and feasible treatment for young and elderly patients with primary hepatic carcinoma.The independent prognostic factors of survival for young patients are pre-operative albumin level <3 5 g/L and the maximum tumor diameter ≥5 cm.

Background Heat shock proteins (HSPs) are highly conserved proteins that are induced in cells when confronted with a wide variety of proteotoxic stresses.HSP27 has a high degree of similarity with α-crystallin protein.The abnormality of HSP27 structure and expression are closely related to the formation of cataracts.Our previous study showed sodium salieylate has the protective effect on H2O2-induced lens damage.Objective This study was to investigate the roles of MAPK signal pathway in sodium salicylate-induced the expression of HSP27 in human lens epithelial cells (LECs) in vitro.Methods Human LECs were incubated in the fresh media containing sodium salicylate at different concentrations (0-55 mmol/L) for different times (1-5 hours) and allowed to be recovered in fresh medium without sodium salicylate for 1-24 hours with or without pretreatment with P38MAPK inhibitor (SB203580), ERK1/2 inhibitor (PD98059) and JNK/SAPK inhibitor ( SP600125). The expressions of P38MAPK, EBK1/2, JNK/SAPK, phosphorylated P38MAPK, phosphorylated ERK1/2, phosphorylated JNK/SAPK and HSP27 were detected by Western blot. HSP27 mRNA was detected by RT-PCR. The expression of HSP27 was also detected by immunohistochemistry. Results There was only weak expression of HSP27 in normal human LECs.After stimulation of 35-55 mmol/L sodium salicylate was removed and human LECs were cultured again for 6 hours,the expression of HSP27 in LECs were significantly increased ( F= 509. 953,P<0. 01). HSP27 was absent expressed in human LECs in 55 mmol/L sodium salicylate stimulation for 1-5 hours groups, but LECs were re-cultured for 3,6 hours after removed the stimulation, the expression of HSP27 was elevated (F = 452. 534, P<0. 01). Activation of P38 M APK occurred after sodium salicylate stimulation 30 minutes and 1 hour ( F = 865.68, P<0. 01). However, ERK 1/2 was expressed after sodium salicylate was eliminated for 1-6 hours ( F = 388.84, P<0. 01). JNK/SAPK was inactived by sodium salicylate. The expression of HSP27 could be down-regulated with the pretreatment of SB203580 and PD98059. Conclusion Sodium salicylatc can induce the expression of HSP27 in human (LECs) . The effects are mediated,at least in part ,through the activation of P38MAPK and ERK1/2 signaling pathway .
