Objective To observe the clinical efficacy of point injection at Xialiao point (BL 34) for levator ani syndrome. Methods A hundred levator ani syndrome patients were randomly allocated to a treatment group and a control group, 50 cases each. The treatment group received point injection at Xialiao point (BL 34) and the control group was intervened by biofeedback therapy. The Visual Analogue Scale (VAS), component scores of the MOS 36-item Short-From Health Survey (SF-36), anal resting and squeeze pressures were recorded in the two groups before and after the treatment. The therapeutic effects and therapy costs were compared between the two groups.Results The VAS, component scores of SF-36, anal resting and squeeze pressures were significantly changed after intervention in the two groups (P<0.05). After treatment, the VAS, a part of the SF-36 score [physiological function (PF), body pain (BP), vitality (VT) and social function (SF) scores], anal resting and squeeze pressures in the treatment group were significantly different from that in the control group (P<0.05). The total efficacy rate was 88.0% in the treatment group versus 80.0% in the control group, and the difference was statistically significant (P<0.05). The therapy costs in the treatment group were (327.31±13.42) RMB and (408.45±21.56) RMB in the control group, and the difference was statistically significant (P<0.01).Conclusions Point injection at Xialiao point (BL 34) is an effective method for levator ani syndrome.

Objective To explore the effect of lysophosphatidic acid(LPA)on blood-brain barrier(BBB) permeability and its possible mechanism.Methods LPA or LPA+suramin(L+S)were stereotaxically injected into the right eaudate nucleus in SD rats in vivo.Evans blue(EB)was used to quantitatively measure the permeability of BBB at different time points.The expression of matrix metalloproteinase-9 was detected by immunohistochemistry technique.The pathological ultrastruetural changes of BBB were assessed by transmission electron microscopy.Results The BBB permeability began to increase after LPA administered into ipsilateral eaudate nucleus,and reached the peak at 24h.Then the permeability of BBB gradually lowered after 48h.In comparison with the same time points of control group,there were quite significant differences(P＜0.01).After L+S was injected,the change of BBB permeability had differences in comparison with those of LPA group in the same time points,(P＜0.05).MMP-9 positive cells were mainly vascular endothelial cells.The numbers of MMP-9 positive blood vessels grew at 6h in LPA group,and the expression of it reached maximum at 24h,then the number of it decreased at 48h,showing significant statistical differences in comparison with the L+S group(P＜0.01),It was observed microscopically that ultrastrueture of BBB of the LPA group was changed sharply,such as basement membrane roughed and fragmented,astroeyte end-feet swolled markedly and perivaseular space enlarged obviously.But there were no remarkable changes in BBB in L+S group.Conclusion LPA can induce increase of BBB permeability and its possible mechanism is the strong expression of MMP-9 protein produeted by endothelial cells through the mediation of LPA receptor,leading to degradation of basement membrane.

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.

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 .

Objective To investigate the clinical features and distribution of G types of rotavirus diarrhea in infants and children in Suzhou and Maanshan areas.Methods 1267 stool specimens were collected from children under 5 years with acute diarrhea. Enzyme-linked immunosorbant assay (ELISA) and nested polymeras chain reaction (Nested-PCR) were used to detect rotavirus and serotypes.Results In 1267 stool specimens, 378 were detected RV positive, and serotype G was the prevalent type in the two cities with number of 250 and the G3 and G1 types were the most prevalent which accounted for 40%(100/250) and 44.40 % (111/250), respectively. While the G2 ,G4, G9 types and mixed infections were 8,3,3,4 and the un-identified type was 8.40%(21/250). G1 type was the most prevalent in Maanshan are which accounted for 58.54% in all cases,while the G3 type accounted for the most of case(47.85%) in Suzhou area.Conclusions The results indicated that rotavirus was the most important etiologic agent in Maanshan and Suzhou areas,G1 and G3 were the most prevalent types,respectively.
