Objective To evaluate the efficacy,drug resistance and safety of combination therapy with lamivudine (LAM) and adefovir dipivoxil (ADV) or entecavir (ETV) monotherapy for chronic hepatitis B (CHB) patients with high viral loads (HBV DNA ≥ 107copies/mL).Methods Seventy CHB patients with high viral loads were collected from Jiangyin People' s Hospital in Jiangsu Province during May 2007 and January 2009.All patients were randomized into combination therapy group and monotherapy group.Combination therapy group was treated with lamivudine ( 100 mg/d) and adefovir dipivoxil ( 10 mg/d) for 96 weeks,and monotherapy group was treated with entecavir (0.5 mg/d) for 96 weeks.x2 test was used to compare the ALT normalization rates,HBV DNA negative rates and HBeAg sernconversion rates between two groups.Results After 96 weeks' treatment,the ALT normalization rate,HBV DNA negative rate and HBeAg seroconversion rate of combination therapy group were 97.1％ (34/35),94.3％ ( 33/35 )and 48.6％ ( 17/35 ),respectively ; those of monotherapy group were 77.1％ ( 27/35 ),77.1％ ( 27/35 )and 17.1 ％ (27/35),respectively ; the differences were of statistical significance (x2 =6.248,4.200 and 7.835,P ＜0.05 or P ＜0.01 ).There was no virological breakthrough in combination therapy group during 96 weeks' treatment,but it was found that 2 patients had virological breakthrough in monotherapy group and they were ETV-resistant.No severe adverse reaction was found in both groups.Conclusion LAM + ADV combination therapy is better in viral suppression,and has lower resistance and higher HBeAg seroconversion rate than ETV monotherapy for CHB patients with high viral load.

Observations were made on the cheek pounches painted with DMBA of 30 golden hamsters for twelve weeks.Histopathological and ultrastructural results of carcinogenesis were observed.With the occurrences of hyperplasia dysplasia and carcinom, a progressively increased euchromatin,nuclearcytoplasmic ratio and increased number of polyribosomes could be observed. However,the number of tonofibrils,desmosomes,heterochromatins and chondriosomes was decreased.Enlarged and multiple nucleoli and mitosis could be seen. Basement membrane was absent in some areas.In a word,the epithelium underwent a progressively active proliferation and poor differentiation during the carcinogenesis

Gemcitabine has become a first-line chemotherapeutic durg.Unfortunately,many patients fail to derive benefits from gemcitabine in clinics.The variability of human equilibrative nucleoside transporter 1 (hENT1)expression in tumor cells,which plays a dominant role in the transport of gemcitabine across the cell membrane,may be one of the reason for gemcitabine chemoresistance in pancreatic cancer.

Objective To evaluate the bladder functions by urodynamic studies in diabetic patients with lower urinary tract symptoms (LUTS). Methods Urodynamic studies were performed in 42 diabetic patients (24 men and 18 women;age range,38-78 years).The diabetic history of the patients was from 1 month to 25 years. Results Of the 41 cases who underwent all items of urodynamic examination,38 cases (93%) had abnormal findings and 3 (7%),normal.The detrusor was underactive in 14 cases (34%) and areflexia in 10 (24%);BOO was found in 13 (32%).One female patient had stress urinary incontinence. Conclusions There is a high prevalence of bladder dysfunction in diabetic patients with LUTS.It is necessary to perform urodynamic studies in diabetic patients before initiation of therapy,especially in patients who are assigned to undergo bladder and urethral surgery.Preoperative urodynamic studies can contribute to the surgical success rate.

Objective: To explore the changes of activity of antioxidases in hippocampus of the rats with multi-infarct dementia and the intervention effects of acupuncture.Method: The multi-infarct dementia model was made by injected emboli into the internal carotid artery.The demented rats were allocated to 3 groups randomly: model,acup and sham-acup;meanwhile normal and sham-operated rats were used as control.The parameters of oxidative stress were assessed by measuring the malondialdehyde(MDA),superoxide dismutase(SOD),catalase(CAT) and glutathione peroxidase(GSH-Px) levels in hippocampus after acupuncture treatment.Result: Compared to normal group,MDA levels of hippocampus in model animals increased significantly,while SOD and GSH-Px decreased much more;No significant difference was observed in CAT among groups.Interestingly,the acupuncture treatment could significantly improve all those indexes.Conclusion: SOD/GSH-Px pathway may be playing a major role in combating oxidative stress in the brain of MID rats,the CAT activity not the key enzyme.Acupuncture treatment could increase the activity of antioxidase SOD/GSH-Px,alleviate the injury of free radical and maintain the oxidant-antioxidant balance to a great extent.This may be one of the mechanisms of its therapeutic effect.

Objective To evaluate pressure-flow study in assessment of dysuresia symptom in elderly male patients. Methods A total of 125 elderly male patients with dysuresia and prostatic enlargement underwent urodynamic examination.Their age ranged from 56 to 83 years with a mean of 68 years.If the patients urinated smoothly with satisfying urinary flow curve,the pressure-flow study would be performed on them.According to the results,the patients were classified as 3 groups:BOO,equivocal BOO and non-BOO groups.Their detrusor contractive function was classified as strong,normal,weak or very weak. Results Of the 125 patients undergoing urodynamic test,87 obtained definite pressure-flow study findings.Of the 87 patients,39 were with BOO,18 with equivocal BOO and 30 without BOO.In the BOO,equivocal BOO and non-BOO groups,detrusor pressure at maximum flow was (99.2?34.3) cmH 2O (1cmH 2O=0.098 kPa),(46.9?9.9)cmH 2O and (30.8?10.0)cmH 2O,respectively;intravesical opening pressure was (99.4?39.6) cmH 2O, (43.7?9.9) cmH 2O and (29.9?9.7) cmH 2O, respectively; minimum voiding detrusor pressure was (61.3?27.5) cmH 2O, (33.9?14.1)cmH 2O and (22.1?12.5)cmH 2O,respectively;and maximum detrusor pressure was (113.0?42.1)cmH 2O,(55.8?14.9)cmH 2O and (38.4?11.3)cmH 2O,respectively.The detrusor function was normal or strong in 74.4% (29/39) of patients with BOO,27.8%(5/18) of patients with equivocal BOO and 26.7% (8/30) of patients without BOO.All these parameters of the BOO group were higher than those of the equivocal BOO group and non-BOO group (both P

OBJECTIVETo explore the relationship between the temperature and time in moxa cone moxibustion with different purities of moxa.

METHODSAccording to the purities, the moxa were divided into a 10 : 1 group, a 20 : 1 group, a 30 : 1 group and a 40 : 1 group, 30 moxa cones in each group. With the VICTOR DM6902 electronic thermometer, the temperature of the undersurface center at different time points during the moxa cone moxibustion with different purities of moxa was measured. Once the moxa cone was ignited, the results were recorded at the end of each second. Also the temperature peak of the undersurface center and the time when the peak occurred were recorded.

RESULTThe undersurface temperature was increased in all the groups; the time of moxa cone reaching the lowest peak temperature was significantly different in all the groups (all P<0. 05), which was the 10 : 1 group, 20 : 1 group, 30 : 1 group and 40 : 1 group from slow to fast. 50 s, 60 s, 70 s, 80 s and 90 s after moxa cone was ignited, the temperature of moxa cone at the same time point was significantly different in all the groups (all P<0. 05), which was the 10 : 1 group, 20 : 1 group, 30 : 1 group and 40 : 1 group from slow to fast. Conclusion Among the moxa with purity of 10 : 1, 20 : 1, 30 : 1, and 40 : 1, the temperature change rate of the low-purity moxa cone is smaller than that of higher purity, and the stimulating duration of the former is longer than the latter. It is believed that the moxa with purity of 40 : 1 is suitable for scarring moxibustion; the moxa with purity of 30 : 1 and 20 : 1 is suitable for the non-scarring moxibustion; the moxa with purity of 10 : 1 is suitable for gentle moxibustion therapy. The high-purity moxa can also be applied to the field of the low-purity moxa.

Objective It is purposed to evaluate clinical efficacy of adefovir dipivoxil combined with anti-tuberculosis (TB) drugs in treatment for chronic hepatitis B (HB) complicated with pulmonary TB. Methods Ninety-four eases of pulmonary TB complicated with chronic HB receiving anti-TB drug treatment at Liaocheng Hospital for Infectious Disease during September 2006 to September 2008 were divided into treatment and control groups matched on their pulmonary TB lesion, damage in liver function and HB virus (HBV) DNA load. Forty-seven cases in the treatment group were administered with anti-TB drugs, i.e., isoniazid (INH) 0. 3 g daily, rifapentine (RFT) 0.45 g twice a week, pyrazinamide (PZA) 1.5 g daily, streptomycin (SM) 0. 75 g daily or ethambutol (EMB) 0. 75 g daily, and regular liver-protection drags, as well as oral adefovir dipivoxil 10 mg daily for eight months, and another 47 cases in the control group were administered with the same anti-TB drugs and regular liver-protection drugs as the treatment group. Two to eight weeks after treatment, clinical symptoms, liver function, HBV DNA load, negative conversion of acid-fast staining bacteria in sputum smear, and absorption of pulmonary TB lesion were evaluated for all the patients in both groups. Data were analyzed with U-test and χ2-test, respectively. Results After treatment, damage in liver function worsened in three cases (6.4%), as compared to that in 47.3 percent of the control group (P<0.05). Clinical symptoms, including tiredness, loss of appetite, abdominal distension, uncomfortable in upper abdomen, and so on, appeared in three cases of the treatment group (6.4%) during anti-TB treatment, as compared to those in 18 cases of the control group (47.3%) (P<0.05). HBV DNA conversed to negative (less than 1.0×103 lg copies/ml) in 24 cases of the treatment group (51.1%), HBV load went down to 1.0×103-1.0×104 lg copies/ml in 23 cases (48. 9%), sputum smear bacteria conversed to negative in 41 cases (87. 2%) and pulmonary lesion absorbed in 45 cases (95.7%), all with statistically significance as compared to those in the control group (47. 3% , 0. 0% , 2. 6% , 39. 5% and 50. 0% , respectively, P <0. 05). Renal function was all in normal in both groups and no patient with drug resistant variant HBV was found during and after treatment, and no obviously adverse reaction was found in patients with adefovir dipivoxil. Conclusion Adefovir dipivoxil has a good safety and can reduce laver damage in anfi-TB drug treatment for patients of chronic hepatitis B complicated with pulmonary TB.
