OBJECTIVESTo determine the effect of destroying capsaicin-sensitive primary afferents (CSPA) fibers on paw withdrawal mechanical threshold (PWMT) induced by the direct compression of L5 nerve root with autologous disc.

METHODSThe procedure used autologous disc of the rats from the coccygeal intervertebral discs to apply direct pressure to the L5 dorsal root. PWMT was measured at the different time points post-surgery and pre-surgery. The changes in spatial expression pattern of c-fos protein in the spinal cord were also determined at 3 weeks when PWMT decreased to the peak.

RESULTSThe pretreatment with capsaicin produced a complete prevention of mechanical hyperalgesia induced by disc compression. The direct compression of L5 nerve root produced an obvious expression of fos-like immunoreactivity neurons in the dorsal horn of the spinal cord, which was significantly decreased by pretreatment with capsaicin.

CONCLUSIONSThe study shows that CSPA fibers, which mainly terminated in superficial layers of dorsal horn, may play a key role in mechanical hyperalgesia in the new sciatica model.

Objective: To observe the clinical effect of acupoint sticking therapy with Mian Tan Gao (facial paralysis paste) plus electroacupuncture (EA) for treating peripheral facial paralysis and its influence on patients' facial nerve functions, facial disability index and clinical symptoms and signs. Methods: A total of 96 peripheral facial paralysis patients were allocated into an observation group, a medicine group and an EA group by simple randomization, with 32 cases in each group. Patients in the medicine group were treated with oral mecobalamine and prednisone acetate; patients in the EA group were treated with EA on the basis of the medicine treatment; while patients in the observation group were treated with acupoint sticking therapy with Mian Tan Gao (facial paralysis paste) plus EA. After 4-week treatment, the clinical efficacy, the adverse events, and the scores of House-Brackmann (H-B) facial nerve function grading scale, visual analog scale (VAS), clinical symptoms and signs, and facial disability index (FDI) were compared. Results: After 4-week treatment, the total effective rate was 96.9％ in the observation group, higher than 68.7％ in the medicine group and 75.0％ in the EA group (both P<0.05). After 4-week treatment, the scores of H-B grading scale, VAS and clinical symptoms and signs in the three groups dropped significantly compared with those before treatment, and the scores in the observation group were lower than those in the medicine group and EA group (all P<0.05). After 4-week treatment, the facial disability index-physical function (FDIP) in the FDI in the three groups increased significantly, with a higher value in the observation group compared with that in the medicine group and EA group (both P<0.05). The facial disability index-social function (FDIS) in the FDI dropped significantly, with a lower score in the observation group compared with that in the medicine group and EA group (both P<0.05). However, the comparisons of the items above between the medicine group and the EA group showed no statistical significance (all P>0.05). The between-group comparison of the adverse event across the three groups showed no statistical significance (P>0.05). Conclusion: Acupoint sticking therapy with Mian Tan Gao (facial paralysis paste) plus EA can decrease H-B grade, reduce pain severity and improve clinical symptoms and signs as well as the facial disability condition in peripheral facial paralysis patients. This method produced more significant efficacy compared with oral medicine and medicine plus EA.

OBJECTIVETo discuss the prognostic factors of recurrent ovarian epithelial carcinoma and to analyze the curative effect of post-relapse treatment.

METHODSThe clinical records of 293 patients with ovarian epithelial carcinoma were reviewed retrospectively. There were 199 recurrent cases during the following up.

RESULTSAll the 199 patients received chemotherapy. And 173 patients only received chemotherapy. 16 patients received surgery and chemotherapy and the other 10 patients received radiotherapy and chemotherapy. 158 patients received platinum-based chemotherapy again and 41 patients received chemotherapy without platinum. The response rate of all the patients was 43.7% (87/199), the response rate of only chemotherapy was 39.9% (69/173), the response rate of surgery and chemotherapy was 75.0% (12/16), and the response rate of radiotherapy and chemotherapy was 60.0% (6/10). The patients were divided into four groups according to the progression free interval (PFI). The response rates in groups that PFI < or = 6 months, 7 - 12 months, 13 - 24 months and > 24 months were 5.1%, 47.2%, 82.1% and 96.0%, respectively. The median survival time in the 16 patients received second cyto-reductive surgery was 41 months. Multivariate analysis revealed that PFI was significantly correlated with prognosis of recurrent ovarian epithelial carcinoma (OR = 0.589, P = 0.021).

CONCLUSIONPFI is an individual prognostic factor for survival of recurrent ovarian epithelial carcinoma. PFI is significantly associated with the response rate of chemotherapy. Optimal secondary cytoreductive surgery may improve the overall survival of recurrent patients. The response rate of paclitaxel plus platinum chemotherapy in platinum-sensitive patients is higher than that of other platinum-based chemotherapy.

OBJECTIVETo develop an HPLC method for determining oxyphyllenodiol A (1) and teuhetenone A (2) contained in Alpinia oxyphylla and to compare the contents of the two components contained in medicinal materials and prepared herbal medicines in pieces sold in the market and different fractions.

METHODHPLC and Waters sunfire C18 column (4. 6 mm x 250 mm, 5 microm) were adopted for gradient elute with the mobile phase of acetonitrile and water. The flow rate was 1.0 mL x min(-1) and the detection wavelength was 250 nm.

RESULT1 and 2 showed a good linear relationship within the range of 0.1296 - 0.8640 microg and 0.1635 - 1.0900 microg respectively, with the average recoveries of 99.08% and 97.80%. Their content ranges were 0.0059% - 0.0149% and 0.0080% - 0.0164% in different samples. The mean value of 1 and 2 were 0.0085% and 0.0104% in the whole fruits, and 0.0137% and 0.0157% in the seeds. They were undetected in the nutshells.

CONCLUSIONThe method is so precise, accurate and highly reproducible that it can be used to determine the contents of oxyphyllenodiol A and teuhetenone A in A. oxyphylla. The contents of the two components are mainly extracted from the seeds, with certain difference among different samples. There are a higher contents and no significant difference in the salted and raw seeds.

Objective To investigate serum levels of soluble matrix lysin 2 (sST2) in patients with different stages of heart failure and its relationship with prognosis. Methods Data of 300 patients with heart failure of stages A, B, C and D were included in this study. Thirty-three cases of healthy elderly population for physical examination were used as control group. The general information, echocardiography and related biochemical tests containing sST2 and NT-proBNP were collected in the two groups. The survival periods of patients were evaluated according to the Seattle heart failure mode (SHFM). Patients were followed up for 1 year to record the occurrence of adverse events. Results The sST2 level was higher in heart failure group than that of control group. The sST2 level began to increase in stage B, and which increased with the development of cardiac function staging. The sST2 levels were significantly higher in stages B, C and D than those of stage A, and which were significantly higher in stage D than those of stages B and C (P<0.05). There were significantly higher incidence rates of adverse events, left ventricular end diastolic diameter (LVEDD) and left ventricular mass index (LVMI) in the patients with high sST2 level than those of patients with lower sST2 level (P<0.05). Values of sST2, NT-proBNP, LVEDD and LVMI were significantly higher, and values of LVEF and SHFM life expectancy were significantly lower, in patients with adverse events than those of patients without adverse events (P<0.05). There was a negative correlation between sST2 and LVEF, and positive correlation between sST2 with NT-proBNP, LVEDD and LVMI (P<0.05). The size under ROC curve, which was used to predict the cardiovascular endpoint events judged by sST2 was 0.665 (95％CI:0.574-0.757, P<0.01), and the one by NT-proBNP was 0.790 (95％ CI: 0.731-0.848, P<0.01). The best cut-off value of predicting the clinical adverse events was 139.27μg/L by sST2 and 855.35μg/L by NT-proBNP. Conclusion The serum level of sST2 is early indicator of heart failure, which not only reflects the severity of ventricular remodeling but also is one of indicators to estimate the prognosis of heart failure in one year.

Objective To explore the significance of designing with monitoring-flap in massive com- pound bone grafts for repairing massive bone defects in extremities.Methods From January 2001 to De- cember 2004,large bone defects in 19 patients(11 men and 8 women,age:6 to 35 years,mean age:18.6 years)were repaired by vascularized free fibular transplant with a monitoring-flap combining with massive deep frozen bone allografts.Average length of the bone defects was 16.6 cm(range,12 to 25 cm).A 7 days' con- tinuously clinical examination including observing the color,turgor,temperature,capillary refill,and bleeding after a needle sticking of the monitoring-falps were used postoperatively,if any one of these were abnormal,the circulation of the compound bone grafts must be in danger and some measures such as re-operation should be taken immediately.Dynamic image analysis was used for evaluating the bone union.Results One monito- ring-flap was vascular artieulo,and the articulo was relieved after exploration and resection of vein thrombus; another one was marginal part necrosis;the remains were normal.All of monitoring-flaps healed normally after 23.2 months(range,6 to 54 months)follow-up.15 patients had the radiographic evidence of bone unions 3 months after surgery.11 patients had been removed intermal fixation,complete bone unios were found one year postoperatively.Conclusion Designing with monitoring-flap in massive compound bone grafts for repairing massive bone defects,and can clearly understand the circulatory statue of compound bone grafts and early pre- dict the final results of massive bone allografts.

A cross-sectional survey with multiple-stage and random sampling was performed among middle and elderly aged permanent inhabitants in Wuhan area.The prevalences of metabolic syndrome,diabetes mellitus, impaired glucose tolerance,hypertension and obesity were 12.2%,11.8%,10.3%,31.9% and 48.0% respectively.

Objective To observe the clinical efficacy of moxibustion in treating knee osteoarthritis (KO) and analyze its cost-effectiveness.Method Fifty-eight KO patients were randomized into a moxibustion group and an electroacupuncture (EA) group, 29 cases in each group. The two groups were treated 3 times a week, for successive 4 weeks. The knee joint function and Visual Analogue Scale (VAS) for knee joint pain were scored before and after the treatment, and the two groups were analyzed by using health economic methods.Result The knee joint function scores were significantly changed after the treatment in the two groups (P<0.05); the excellent rate was 96.6％ in EA group versus 75.9％ in moxibustion group, and the general excellent rate in EA group was markedly higher than that in moxibustion group (P<0.05); the total effective rate for pain was 93.1％ in moxibustion group versus 96.6％ in EA group, and the between-group difference was statistically insignificant (P>0.05). The cost-effectiveness ratio was 6.42 in moxibustion group versus 16.86 in EA group; the incremental cost-effectiveness ratio was 298.55 in EA group. Conclusion Moxibustion and EA both can effectively improve knee joint function and mitigate knee joint pain, while compared with EA, moxibustion has a higher health economic value.
