OBJECTIVETo explore the therapeutic effects of amiodarone and metoprolol, either alone or in combination, on chronic heart failure (CHF) complicated by ventricular arrhythmia.

METHODSA total of 110 NYHA class II-III patients with CHF complicated by ventricular arrhythmia were randomly divided into amiodarone group, metoprolol group and amiodarone + metoprolol group. The therapeutic effects was evaluated at the end of the 1-year follow-up.

RESULTSAmiodarone, metoprolol and their combination produced statistically different therapeutic effects (P<0.05). Compared with amiodarone and metoprolol used alone, amiodarone combined with metoprolol resulted in significant cardiac function improvement (P<0.05) and ventricular arrhythmia control (P<0.01). During the 1-year follow-up, the readmission rate and cardiac event rate in the amiodarone + metoprolol group were significantly lower than those in amiodarone group (P<0.01) and metoprolol group (P<0.05). The adverse reaction rates in the 3 groups were similar (P>0.05).

CONCLUSIONThe combination of amiodarone and metoprolol produces better effect than amiodarone or metoprolol alone in the treatment of CHF complicated by ventricular arrhythmia.

Objective Labial gland biopsy is one of major diagnostic methods for Sj(o)gren's syn-drome(SS).Meanwhile,99TcmO-4 parotid scintigraphy has been proven useful for the clinical evaluation of SS.This study was performed to investigate the correlation between the two examinations and evaluate the semi-quantitative parotid scintigraphy in the early diagnosis and staging for SS patients.Methods There were 135 SS patients and 30 normal subjects as control group in this study.They all underwent 99TcmO-4 pa-rotid scintigraphy.Semi-quantitative analyses of parotid scintigraphy were conducted with parameters inclu-ding maximum accumulation ratio (MAR),maximum secretion ratio(MSR),time interval from stimulation to minimum count(tparotid),prestimulatory oral activity index (PRI) and poststimulatory oral activity index (POI).For comparison, the biopsy of labial gland was performed in each patient and the pathological se-verity was classified into grade 0,1,2,3,4 (also defined as subgroups).One-way ANOVA and q-teat were applied for the correlation analyses between the two examinations.Results There was significant difference between pathological subgroup 3 or subgroup 4 and the control in all the semi-quantitative parame-ters (q=6.79-38.64,P<0.O1).In subgroups 1 and 2,only PRI and POI showed significant changes compared with the control(q=8.33,8.63,all P<0.01).The pathological stages were negatively correla-ted with MAR(r=-0.679,P<0.01),MSR(r=-0.601,P<0.01),PRI(r=-0.724,P<0.01)and POI(r=-0.751,P<0.01),but only positively correlated with tparotid(r=0.364,P<0.01).Con-clusions Most semi-quantitative parameters of 99TcmaO-4 parotid scintigraphy may be well correlated with the pathological severity of labial gland biopsy in SS patients.Further,the semi-quantitative indices espe-eially PRI and POI may be helpful for the early diagnosis and staging of SS patients.

To determine the immunoreactive pattem of human papillomavirus (HPV) antigen and p53 protein in condylomata acuminatum (CA) and squamous cell carcinoma (SCC) of penis. Methods: Immunohistochemistry for HPV and p53 were performed in 40 specimens of formalin fixed, paraffin embedded tissues using a polyclonal (rabbit) antibody against HPV and a monoclonal (mouse) antibody against human p53 protein. Twenty one cases of CA and nineteen cases of SCC were examined. Results: HPV antigen was detected in all 21 CA and 2 penile SCC. p53 protein overexpression was observed in 12 of 19 (63%) SCC in which 6 cases were strong positive. Five of 21 CA (24%)showed low-grade p53 protein overexpression. Conclusion: CA is related to HPV infection and some cases show p53 protein low-grade overexpression. In contrast, p53 protein overexpression is common in penile SCC, which is seldom related to HPV infection.

To study the effect of pulchinenoside (PULC) on the Frizzled (FZD) expression of adjuvant arthritis ( AA) rats. AA rats were prepared through the toe injection with complete Freund's adjuvant to culture fibroblast-like synoviocytes (FLS). The effect of the oral administration with PULC on the FZD8 expression was detected by the real time qPCR. The effect of FZD8 knockout on the expressions of IL-1, IL-6, IL-8 were detected by MTT and ELISA. The role of miR-375 in the abnomal expression of FZD8 was detected by the real time qPCR. The results showed signfiicant decrease in the FZD8 expression among AA rats, FLS proliferation ater FZD8 knockout and IL-1, IL-6, IL-8 expressions and notable increase in miR-375 expression after the oral administration with PULC. The up-regulated miR-375 expression can inhibit the FZD8 expression. PULC may inhibit the FZD8 expression by up-regulating the miR-375 expression.

Objective To observe the influence of coal burning fluorosis on learning and memory ability in rats and reveal its possible mechanisms. Methods Healthy 48 SD rats were divided into control, low-fluoride and high-fluoride group. All rats in fluoride exposed groups were fed with the eom polluted by drying processes with burning coal containing high level of fluoride obtained from the endemic fluorosis area to produce the animal model of fluorosis. The experiment period were 3,6 mouths, respectively. The ability of leaning and memory was measured by Morris test and cholinesterase activity detected by photometric method at 3 or 6 month after experiment, respectively. Results Fluoride contents signifieantlly influenced the escape latency, the numbers of crossing the platforms and the time of staying the platforms(the value of F was 29.29,6.47,6.50, respectively, P<0.01).In addition, the numbers of crossing the platforms and the time of staying the platforms were influenced by the exposed time(the value of F was 16.11,45.59, P<0.01). Furthermore, the fluoride contents and the exposed time had an interaction between the numbers of crossing the platforms and the time of staying the platforms (the value of F was 4.67,5.68, P<0.05 or<0.01). Three months after the experiment, the mean values of escape latency [(14.71± 4.85)s] of rats in highly fluoride exposed group were significantly prolonged as compared with controls [(9.28±4.22)s]; 6 month after the experiment, the mean values of escape latency[(12.42±8.03)s, (17.48± 8.05)s] of rats in both groups exposed to fluoride were significantly prolonged as compared to controls [(7.04± 3.29)s, P<0.05]. The decreased numbers of crossing the platforms[(1.62±0.87)number] and the declined time of staying the platforms[(16.70±5.02)s] were found in the rats exposed to high fluoride as compared to controls [(3.53±1.67 )number, (23.33±5.35)s, P<0.05]. The fluoride contents obviously influenced the activities of acetylcholinesterase and butylcolinesterase (the value of F was 12.83,13.27, P<0.01). On the other hand, the times of breeding also influnced the activities of butylcolinesterase (the value of F was 16.26, P<0.01). In 3 months of the experiment, the activities of butylcolinesterase [(0.55±0.12)kU/g] in low fluoride exposed group were significantly decreased in comparison with controls[(0.73±0.10)kU/g, P<0.05]. The activities of acetylcholinesterase[(0.62±0.42)kU/g] and butylcolioesterase[(0.58±0.10)kU/g] in high fluoride group were significantly decreased as compared to eontrois[(1.41±0.52), (0.73±0.10)kU/g, P<0.05]. The correlation analysis showed that there was a negative correlation between the cholinesterase and the escape latency(r=-0.68, P< 0.01), and a positive correlation between the cholinesterase and the time of staying the platforms(r=0.57, P< 0.01). Conclusions The ability of learning and memory in rats with coal buring fluorosis was decreased, which might be connected to the decreased activity of cholinesterase in a dose-effect correlation.

The role of pulchinenoside (PULC) in the regulation of MeCP2 expression was investigated in RA model rats. Adjuvant arthritis rats were used as RA model rats, and fibroblast-like synoviocytes (FLS) from the RA model rats were cultured. The effect of 100 mg x kg(-1) PULC gavage treatment on the MeCP2 expression and the effect of MeCP2 siRNA on the expression of SFRP2 and β-catenin were detected by real time qPCR and Western blotting. The role of PULC in the FLS proliferation was detected by MTT. The results showed that the MeCP2 expression was down-regulated, the SFRP2 expression was up-regulated and the FLS proliferation was inhibited in FLS after therapy. MeCP2 siRNA significantly inhibited the MeCP2 expression, up-regulated the SFRP2 expression and inhibited the β-catenin expression in FLS from RA model rats. PULC may increase the SFRP2 expression, inhibit the Wnt signaling and inhibit the FLS proliferation in FLS from the RA model rats by inhibiting the MeCP2 expression.

BACKGROUNDCurrently, all the diagnostic indicators for endometriosis lack perfect sensitivity and specificity. According to the characteristic of endometriosis, we analyzed the new biomarker neutrophil-to-lymphocyte ratio (NLR) and the combination of NLR and serum CA-125 to investigate their diagnostic value for identifying stages III and IV endometriosis.

METHODSThe values of serum CA-125 and routine blood tests were collected from 197 patients with endometriosis, 102 with benign tumors and 112 healthy individuals. We investigated the sensitivity and specificity of NLR and its combination with serum-CA-125 for diagnosing stages III and IV endometriosis by using receiver operating characteristic (ROC).

RESULTSThe mean values of NLR, the combination of serum CA-125 and NLR (combination) of the groups with stages III and IV endometriosis were significantly higher than the other two groups. Serum CA-125, NLR, and the combined biomarkers could significantly discriminate the stages III and IV endometriosis group from the other two groups (P < 0.05). NLR shows a lower sensitivity of 57.9% and specificity of 65.2% with a cutoff value at 1.82. And the combination of biomarkers has the highest AUC of 0.949 with a sensitivity of 86.8% and specificity of 92.0% at the cutoff value of 44.40. In addition, for patients with negative CA-125, 55.36% and 53.57% of the patients were able to be diagnosed with endometriosis by using NLR alone and the combination of biomarkers.

CONCLUSIONFor diagnosing stages III and IV endometriosis, the neutrophil-to-lymphocyte ratio is a better adjuvant to serum CA-125, and the neutrophil-to-lymphocyte ratio is valuable in diagnosing stages III and IV endometriosis for patients with negative serum CA-125.

OBJECTIVETo observe the characteristics of uterine contraction and stages of labor during delivery under continuous epidural block anesthesia.

METHODSTotaling 213 parturients in spontaneous labor under epidural block anesthesia with dilated cervical orifice of 3 cm were monitored for the contraction cycle, duration, intensity and curve types of uterine contraction, and recordings were made for 30 min before and 30, 60 and 120 min after the anesthesia took effect, respectively. The duration of the active phase in the first, second and third stages of labor was compared between 421 cases with anesthesia and 237 without anesthesia.

RESULTSSignificant difference was noted in the objective indexes of uterine contraction recorded after anesthesia had taken effect (P<0.05) in comparison with those before anesthesia, suggesting significantly attenuated uterine contraction after anesthesia, whereas these indexes underwent no significant further variation as compared between different time points after anesthesia (P>0.05). The average active phase in the first stage was significantly shorter in anesthesia group than that in the control group (P<0.05), but the average duration of the second and third stages of labor differed little between the two groups with appropriate use of oxytocin under strict monitoring (P>0.05). The rates of obstetric forceps utilization and use of oxytocin were higher in anesthesia group than in the control group (P<0.05).

CONCLUSIONEpidural block anesthesia produces certain influences on uterine contraction and stages of labor during delivery, for which appropriate treatment measures may prove beneficial.

OBJECTIVETo retrospectively study medium-term follow-up outcomes of total hip arthroplasty (THA) for patients with ankylosing spondylitis (AS).

METHODSFrom January 2000 to December 2008, 67 patients (88 hip joints) with AS were treated with all ceramic interface THA. And 55 patients (74 hips) were finally followed up. Among them, there were 30 males and 25 females, with an average age of 32.6 (ranged 19 to 58) years old. Sixty-one hips were treated with biological prosthesis and 13 hips were treated with hybrid prosthesis. Fifty-five patients were followed up at least 5 years, with an average of (75.2 +/- 8.6) months. Clinical symptoms and radiography information were evaluated after follow-up.

RESULTSHarris hip score were significantly improved from 30.8 +/- 7.0 preoperatively to 85.2 +/- 5.5 at the last follow-up (P<0.01). The hip movement range increased from (21.2 +/- 8.5) degrees preoperatively to (142.0 +/- 10.2) degrees postoperatively (P<0.01). The 5-year survival of prosthesis was 95.9%. One patient were renovated because of internal wall broken caused by injury, 1 was renovated for infection, 1 was renovated for fracture arround femoral stem prostheses, and 1 was treated with conservative treatment by dislocation. Three cases with abnormal sound were cured with non-operation. 7 cases with heterotopic ossification were not treated, 2 cases with thigh pain received conservative treatment. Bone dissolve around prosthesis, loose and sink of femur and acetabulum prosthesis were occurred in other cases.

CONCLUSIONTHA for the treatment of AS is a reliable method, which has a satisfied medium-term follow-up outcomes.
