Objective: To observe the clinical efficacy of warm needling moxibustion plus Tuina (Chinese therapeutic massage) for knee osteoarthritis (KOA).Methods: A total of 60 patients with KOA were randomized into an observation group and a control group by the random number table, with 30 cases in each group. The control group was treated with warm needling moxibustion, and the observation group was treated with additional Tuina treatment. The treatments were performed once every other day, for a total of 10 times. The visual analog scale (VAS) and Western Ontario and McMaster Universities osteoarthritis index (WOMAC) were scored before and after treatment, and the surface electromyography (sEMG) signals of quadriceps femoris were collected. Results: The total effective rate of the control group was 76.7％, and that of the observation group was 90.0％. The difference between the two groups was statistically significant (P<0.05). The WOMAC and VAS scores in both groups after treatment were improved, and the integrated electromyography (iEMG) and median frequency (MF) of quadriceps femoris were increased. The intra-group differences were statistically significant (P<0.05). After treatment, the WOMAC and VAS scores in the observation group were lower than those in the control group, and the differences between the two groups were statistically significant (P<0.05). The improvement of quadriceps femoris function in the observation group was more notable than that in the control group, and the iEMG value and MF were significantly higher than those in the control group (P<0.05). Conclusion: Warming needling moxibustion plus Tuina can effectively relieve the pain in patients with KOA, improve their daily activity function, and increase the sEMG signals of the quadriceps femoris.

Objective To investigate the expression of aquaporin-4 (AQP4) in contused brain and contralateral side and correlation of AQP4 level with brain edema.Methods A total of 70 health adult SD rats were divided into sham operation group (n =10) and brain contusion group (n =60) according to the random number table.Except for no impact in sham operation group,the remaining operations were the same in both groups.Ten rats in brain contusion group were separately sacrificed at 1,6,24,48 and 72 hours,and 7 days.Pathological changes in brain tissues of rats were detected and immunohistochemistry staining and Western-blot were used to measure AQP-4 expression.Results There were no abnormalities of brain tissue structure in sham operation group with AQP4 expressed mainly in glial cells and vascular endothelial cells.With respect to the injured side in brain contusion group,mixed brain edema that consisted of angioedema and cellular edema occurred along with tissue necrosis,massive inflammatory cell infiltration,and microgial proliferation.AQP4 was apparently expressed in gliocytes and vascular endothelial cells,which showed a fall at 1 hour,the lowest at 6 hours,the peak at 24 hours,slow fall at 48 hours,a second peak at 72 hours,and then a fall until 7 days.Level of AQP4 other than that at 1 hour had significant difference compared with sham operation group (P ＜ 0.01).Whereas the contralateral side in brain contusion group showed no pathological abnormalities at 1 hour,but cellular edema emerged at 6 hours followed by mixed brain edema mainly characterized as cellular edema at 24 hours,continued cellular edema but alleviated angioedema at 48 and 72 hours,and alleviated cellular edema at day 7.AQP4 was up-regulated in gliocytes and vascular endothelial cells,which decreased at 1 hour (1.313 ± 0.01),minimized at 6 hours (0.922 ± 0.03),peaked at 24 hours (2.848 ± 0.020),fell at 48 hours,peaked again at 72 hours (2.662 ± 0.02) and fell to almost normal level at day 7.By contrast with sham operation group,level of AQP4 had significant difference other than that at 1 hour and 7 days (P ＜ 0.01).Conclusions After brain contusion,angioedema and subsequent cellular edema emerge in the contused side.Pathological changes are delayed in non-contused side with cellular edema ahead of angioedema.Level of AQP4 is closely related with traumatic brain edema.

Objective To explore clinical indications and curative effects of microwave coagulation combined with submucous 5-fluorouracil (5-FU) injection in the management of early-stage lower rectal cancer. Methods Nine patients with early-stage lower rectal cancer underwent microwave coagulation with submucous 5-FU injection from January 1996 to December 2002. After the microwave treatment, a retention enteroclysis with 100~200 ml normal saline containing 1.0 g 5-FU was performed once daily for 3 days. Results In 3 patients, levels of carcinoembryonic antigen (CEA), which were preoperatively increased, were reduced below normal limits after microwave treatment. No hemorrhage or other intra- or post-operative complications was observed. Follow-up observations to January 2006 showed that all the 9 patients survived. One patient survived for 3 years and 5 months, 1 patient survived for 3 years and 8 months, and 1 patient experienced a tumor relapse at 1 year and 4 months and survived for 2 years and 9 months after a Miles procedure. Among 6 patients who survived longer than 5 years, 1 survived for 5 years and 1 month, 1 for 6 years and 3 months, 1 for 6 years and 8 months, 1 for 7 years and 6 months, and 2 for 9 years. Conclusions Surgical indications for microwave coagulation combined with submucous 5-FU injection for rectal cancer included early-stage cancer, lesions located within 7 cm away from the anus, the mass type cancer, tumor diameter at 0.5~3.0 cm or less than one third of the rectum’s circumference, well differentiated tumor, and patient’s strong anus-sparing demand. This method is minimally invasive, safe, reliable, and cost-effective.

Objective: To investigate the inhibition of tanshinoneⅡA (TanⅡA) on the proliferation of lung cancer cells. Methods: Human lung cancer cell lines A549, SK-MES-1, H446 and H460 were cultured in vitro and treated with TanⅡA at concentrations of 0.3, 0.6, 1.3, 2.5, 5.0, 10.0 mg/mL, while untreated cells served as controls. Cell proliferation was measured by using CCK-8 assay, and apoptosis was measured using flow cytometry, while the expression of apoptosis-related proteins was determined using Western blotting. The apoptotic rate of lung cancer cells was compared between Tan ⅡA-treated cells and untreated cells. Results: Tan ⅡA inhibited lung cancer cell proliferation in a time-dependent and concentration-dependent manner, and the survival rates of A549, SK-MS-1, H446 and H460 cells reduced with the concentration of TanⅡA (t=4.503, 2.114, 2.103 and 3.567; all P<0.05) and the duration of TanⅡA treatment (t=5.189, 3.079, 3.023 and 3.845; all P<0.05). The 48 h half maximal inhibitory concentrations (IC50 values) of TanⅡA were (1.18±0.12), (0.78±0.08), (1.55±0.16) and (1.27±0.14) mg/mL against A549, SK-MES-1, H446 and H460 cells, respectively. Following 48 h treatment with Tan ⅡA at a concentration of 2.5 mg/mL, the apoptotic rates of A549, SK-MS-1, H446 and H460 cells were (34.97±3.78)%, (37.62±2.48)%, (18.27±2.98)% and (19.17±2.30)%, which were significantly significantly higher than those of untreated cells [(4.86±0.36) %, (3.21±0.48) %, (3.25±0.26)% and (2.66±0.19)%, all P<0.05]. Reduced Akt1 protein expression, elevated Bax/Bcl-2 expression ratio, and elevated caspase-9 and caspase-3 protein expression were detected in lung cancer cells treated with 2.5 mg/mL TanⅡA for 48 h relative to untreated cells Conclusion TanⅡA may inhibit lung cancer cell proliferation in a time- and concentration-dependent manner via the Bax/Bcl-2/caspase-9/caspase-3 pathway.

OBJECTIVE: To observe the effects of matrine on proliferation and apoptosis of human renal cell carcinoma cell line GRC-1 in vitro, and to explore its mechanism. METHODS: The human renal cell carcinoma cell line GRC-1 was treated with matrine of different concentrations for 24, 48, 72 and 96 h respectively. The MTT assay was used to evaluate the cytotoxic effects of matrine on GRC-1 cells. The transmission electron microscope and flow cytometry were utilized to observe and detect the apoptosis of GRC-1 cells induced by matrine. The expression levels of Bcl-2 and Bax proteins were evaluated by streptavidin-biotin-peroxidase method. RESULTS: The matrine of different concentrations all have cytotoxic effects on GRC-1 cells, with obvious dose- and time-dependent effects. The apoptosis induced by matrine was confirmed in GRC-1 cells. With intervention of matrine (1.5 g/L) for 12 h, the expression level of Bcl-2 in GRC-1 cells was decreased while the expression level of Bax was increased as compared with those in the untreated group. CONCLUSION: The proliferation-inhibiting effects of matrine on human renal cell carcinoma cell line GRC-1 may be related to down-regulating the ratio of Bcl-2/Bax protein expression and promoting the apoptosis.

Objective To investigate the effect of point Zusanli acupuncture on serum creatine kinase (CK) and creatine kinase isoenzyme (CK-MB) in high-intensity military training soldiers and explore its possible antifatigue mechanism.Methods Sixty healthy soldiers were randomly allocated to groups A and B, 30 each. Group A received acupuncture at point Zusanli and group B, no treatment. After two weeks of treatment, two groups of soldiers separately did 5 km high-intensity running training and fulfilled the requirement of army examination. CK and CK-MB were measured in two groups before and after training and five days after training.Results In the two groups, there were statistically significant differences in serum CK and CK-MB contents between before training and after or five days after training (P<0.05). After or five days after training, there were statistically significant differences in serum CK and CK-MB contents between groups A and B (P<0.05).ConclusionsAcupuncture at point Zusanli can effectively improve bodily antifatigue ability and reduce myocardial and skeletal muscle injury caused by high-intensity exercise in military training soldiers.

Objective To investigate the effects of different acupuncture therapies on serum branched-chain amino acids (BAC and free tryptophan (F-Trp) in high-intensity military training soldiers. Methods Ninety healthy soldiers were randomly allocated to groups A, B and C, 30 soldiers each. Group A received treatment with electroacupuncture at Zusanli; group B, treatment by cupping on Zusanli;group C, no treatment. The three groups did a high-intensity 5 km running exercise after two weeks of treatment. Serum BACC and F-Trp contents were measured in the three groups before and at the end of treatment and at five days after treatment. Results It can be seen from table 2 that there were no statistically significant pre-treatment differences in serum BACC and F-Trp contents between the three groups of soldier subjects (P>0.05); there were statistically significant pre-/post-treatment differences in serum BACC and F-Trp contents in the three groups of soldier subjects (P＜0.05). There was a statistically significant post-treatment difference in serum BACC content between group A or B and group C (P＜0.05). There was a statistically significant difference in serum F-Trp content between group A or B and group C at the end of treatment and at five days after treatment (P＜0.05). Conclusion Acupuncture therapy can effectively improve bodily anti-fatigue ability and reduce high-intensity exercise induced muscular injury in military training soldiers.

Objective To investigate changes in the intraocular pressure(IOP) and anterior chamber angle in patients with chronic renal failure before and after hemodialysis. Methods Fifty?eight patients(116 eyes) with chronic renal failure were measured with Goldmann applanation tonometer and anterior segment optical coherence tomograph. The patients were divided into three groups based on gonioscopy results:the narrow angle group(22 eyes),the Iris neovascular group(3 eyes)and the open angle group(91 eyes). IOP was measured by Goldmann applanation tonometer in patients in the three groups before and after hemodialysis. Anterior chamber angle opening distance (AOD) was detected by anterior segment optical coherence tomograph before and after hemodialysis. The blood urea nitrogen,creatinine,albumin were also determined before and after hemodialysis. All changes in the parameters were analyzed with a paired t test. Results The IOP in narrow angle eyes and in neovascular eyes increased significantly after hemodialysis ,while the IOP in open angle eyes showed no significant changes. The AOD decreased significantly after hemodialysis. The blood urea nitrogen and creatinine decreased significantly in 58 patients,while albumin increased after hemodialysis. Conclusion The IOP in narrow angle eyes and in neovascular eyes increased after hemodialysis ,correlating with the resistance increase of aqueous outflow pathway and the change of plasma osmotic pressure. As a result ,it is recommended that the condition of eye of patients with chronic renal failure should be checked ,and patients should receive appropriate controlling measure or treatment before hemodialysis.
