Objective To observe the clinical curative effect of combination of traditional Chinese and western medicine for treatment of patients with hepatitis B virus (HBV) related acute-on-chronic (subacute) liver failure (ACLF). Methods A prospective randomized controlled trial was conducted; 66 cases of HBV-ACLF patients were randomly divided into two groups: a test group (44 cases) and a control group (22 cases). Conventional western medicine treatment was given to both groups; the patients in test group additionally received the traditional Chinese medicine (TCM) in accord to the principles of differentiation of syndromes in TCM, in cases with damp-heat and blood stasis syndrome with yellow appearance, Liangxue Jiedu Huayu decoction (Paeoniae Radix Rubra 60 - 150 g, Artemisiae Scopariae Herba 30 - 90 g, Gardeniae Fructus 9 - 12 g, Hedyotis diffusa Willd 20 - 30 g, Salviae Miltiorrhizae Radix et Rhizoma 30 g, Atractylodis Macrocephalae Rhizoma 30 g, Rubiae Radix et Rhizoma 30 - 45 g, Siegesbeckiae Herba 30 - 45 g, Bletillae Rhizoma 15 g ) was given, in cases with Qi deficiency and blood stasis with yellow appearance, Yiqi Jiedu Huayu decoction (Astragali Radix Preparata Cum Melle 30 g, Pseudostellariae Radix 15 g, Artemisiae Scopariae Herba 30 - 60 g, Polygoni Cuspidati Rhizoma et Radix 15 - 30 g, Salviae Miltiorrhizae Radix et Rhizoma 30 g, Aconiti Lateralis Radix Preparata 10 - 15 g, Atractylodis Macrocephalae Rhizoma 30 g, Rubiae Radix et Rhizoma 30 - 45 g, Siegesbeckiae Herba 30 - 45 g, Gigeriae Galli Endothelium Corneum 20 g) was given, the dosage in both groups being 1 dose daily, one dose was prepared to a water decoction 250 - 300 mL which was divided into two parts, one part taken twice a day; the control group received only western medicine treatment. After 2 weeks of treatment, the clinical comprehensive curative effect, the syndrome score efficacy, and the changes of main indexes of liver function,cholinesterase (ChE), albumin (Alb), prothrombin activity (PTA) were observed in the two groups.Results The clinical total efficacy in the test group was significantly higher than that in the control group [75.0% (33/44) vs. 45.5% (10/22),P < 0.05]. The syndrome score total efficacy in the test group was also higher than that in the control group [75.0% (33/44) vs. 63.6% (14/22)], but the difference was not statistically significant (P > 0.05). After treatment, the alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil) and direct bilirubin (DBil) were all lower than those before treatment in both groups, while the ChE, Alb and PTA were higher than those before treatment, and the degree of changes was more significant in the test group [test group: ALT (U/L): 63.28±99.28 vs. 574.58±571.08, AST (U/L): 86.84±92.88 vs. 438.20±482.74, TBil (μmol/L): 161.90±178.34 vs. 269.46±95.10, DBil (μmol/L): 115.32±126.51 vs. 209.12±79.78, ChE (U/L): 4 239.14±1 505.00 vs. 3 341.49±1 609.40, Alb (g/L): 32.65±4.77 vs. 29.73±3.31, PTA: (69.69±44.92)% vs. (32.84±7.47)%; control group: ALT (U/L): 93.28±93.86 vs. 365.24±376.98, AST (U/L): 126.26±121.35 vs. 287.17±301.04, TBil (μmol/L): 226.80±187.38 vs. 281.02±103.73, DBil (μmol/L): 172.50±147.32 vs. 227.96±87.20, ChE (U/L): 4 484.66±1 886.53 vs. 3 918.77±1 417.77, Alb (g/L): 33.17±4.76 vs. 30.47±3.03, PTA: (63.80±36.80)% vs. (33.96±6.32)%,P < 0.05 orP < 0.01].Conclusion The combination of TCM and western medicine for treatment of HBV-ACLF can improve liver function, and the prognosis is superior to using western medicine treatment alone.

Objective To investigate the resistance of multi-drug resistant Acinetobacter baumannii against aminoglycosides and its resistance genes.Methods The minimal inhibitory concentrations (MICs) of seven antimicrobials (gentamicin, amikacin, tobramycine, netilmicin, neomycin, streptomycin and kanamycin) against 20 strains of multi-drug resistant Acinetobacter baumannii were detected by agar dilution method. Meanwhile, two resistance genes of aminoglycoside nucleotidyltransferase were amplified by PCR and vertified by DNA sequencer.Results It was found that MIC50 and MIC90 of gentamicin, amikacin, streptomycin and kanamycin in 20 strains of Acinetobacter baumannii were all above 1 024 mg/L, and their resistant rates were 95%, 95%, 100% and 90% respectively, while the resistant rates of tobramycin, netilmicin and neomycin were 85%, 90% and 40% respectively. Two aminoglycoside-modification genes ant(2″)-Ⅰ and ant(3″)-Ⅰ were detected in 20 strains, with 55% and 80% of positive rate respectively. The double positive rate of two resistance genes was 50%.Conclusion The resistance of multi-drug resistant Acinetobacter baumannii against aminoglycosides was closely associated with ant(2″)-Ⅰ and ant(3″)-Ⅰ genes.

Objective To study the radiographic features of pulmonary sclerosing hemangioma (PSH), and to correlate the imaging with the pathologic findings so as to improve the imaging diagnostic abilities. Methods The clinical features of 45 patients with pathology proved PSH between 1976 and 2002 were reviewed. Of the 45 patients, there were 3 men and 42 women, their age ranged from 18 to 67 years (median age, 49 years), and 19 patients were asymptomatic. 20 patients had chest radiography and CT scans. The radiographic findings were studied retrospectively and were correlated with that of pathology. (7 patients) underwent unenhanced CT and 13 patients had enhanced CT. Results Of the 20 patients who had chest X-ray, 18 patients presented as a solitary, round or oval shaped lesion with well-defined margin. On CT scans, the greatest dimension of the lesion ranged from 1.9 cm to 7.0 cm. A homogeneous soft-tissue attenuation was revealed on unenhanced scans. Homogeneous enhancement was detected in 9 patients and heterogeneous enhancement in 4 patients on enhanced CT. Cystic change was found in 1 patient showing lower attenuation than the enhanced solid tumor, and calcification was found in 5 patients. Correlation of radiographic and pathologic findings indicated that higher attenuation areas corresponded to the angiomatous areas. Conclusions PSH should be considered with the following features: (1) female patients between (40-60) years of age; (2) well-defined round or oval shaped lesion on chest radiography; (3) a homogeneous soft-tissue mass on unenhanced CT; cystic-like area within the tumor and/or calcification can occasionally be found; (4) homogeneous or heterogeneous enhancement after contrast administration.

Methods Fifteen cervical discs were obtained from patients of CSM undergoing anterior disc surgery. Six cervical discs specimens were obtained in the surgical operation with patients with traumatic cervical injury served as the control. The specimens were analyzed for IL 1?、TNF ? by use of ELISA method, NO was measured by optical density assays. Results The contents of IL 1?,TNF ? and NO in disc of CSM patients increased significantly when compared with the control group. Conclusion The results of the present study indicated that IL 1?,TNF ? and NO may be involved in the pathogenesis of CSM.

OBJECTIVE To investigate the distribution and drug-resistance of extended-spectrum ?-lactamases((ESBLs)) producing Gram-negative bacteria in the hospital,in order to control and treat them.METHODS The bacteria were detected and isolated with VITEK TWO system,the suspected ESBLs producing bacteria were(detected) with K-B method.RESULTS There were 1 889 isolated strains of Enterobacteriaceae and the ESBLs(producing) bacteria were 302 strains including E.coli(551),K.pneumoniae(583),and others bacteria(755).Their(positive) rates bacteria were 18.5%,24.7%,and 7.4%,respectively;the wards isolated rate was in the following order: 38.2% were in surgical ICU,29.9% in medical ICU,20.5% in surgery wards,20.6% in oncology wards,12.7% in respiratory wards.12.4% in hematology wards,10.3% in cadre wards,6.4% in endocrinology wards,and 1.6% were in(others) wards.ESBLs producing bacteria were better sensitive to imipenem and meropenem,then to piperacillin(/tazobactam) and cefoperazone/sulbactam.CONCLUSIONS(Enterobacteriaceae) could be(detected) accurately with VITEK TWO system.The main sources of ESBLs producing bacteria are patients in ICU and chronic(patients).To kill these bacteria,imipenem and meropenem can be used first,then(piperacillin)/tazobactam and(cefoperazone)/sulbactain.

BACKGROUND:In rabbit femur fracture model experiment, there are a few studies on whether quadriceps tendon wil affect the stability of the fixed device. OBJECTIVE:To analyze the effects of quadriceps tendon to the stability of external fixator in rabbit models of femur fracture. METHODS:The 48 New Zealand white rabbits were randomly divided into two groups. External fixator was used to make fracture model. In the experiment group, quadriceps tendon was cut. In the control group, quadriceps tendon was retained. 2 weeks later, X-ray examination was utilized to observe the number of failed external fixator in both groups from modeling to success. RESULTS AND CONCLUSION:(1) X-ray examination:2 weeks after model establishment, external fixation frame screw was free from femur in one rabbit of the experiment group, and seven rabbits in the control group. Of them, one screw was broken. Threaded portion retained in the femur. (2) External fixation failure rate:failed external fixator was found in one rabbit in the experiment group, resulting in a failure rate of 4%, and 12 rabbits in the control group, resulting in a failure rate of 50%(P<0.05). These findings suggested that cutting off the rabbit quadriceps tendon can effectively ensure the stability of the external fixator, and indirectly improve success rate of the experiment.

Objective Investigate the reasonable surgical approach combined with frozen sections pathological features of papillary thyroid microcarcinoma.Methods Clinical data of 96 cases papillary thyroid microcarcinoma nearly 5 years of follow-up in our clinic referral was retrospectively analyzed.Metastasis and recurrence rate were compared between group of ipsilateral lobe plus isthmus resection (unilateral group) and group of ipsilateral lobe plus isthmus resection and contralateral lobe subtotal (bilateral group).Metastasis and recurrence rate were compared between group of central lymph node dissection (dissection group) and non-dissection group (non-dissection group),and the injury rate of the recurrent laryngeal nerve was also compared between the two groups.Results The diagnosis of cancer by intraoperative frozen pathology were 53 cases (55％).Whether in high or low risk populations,the metastasis and recurrence between unilateral and bilateral groups showed no significant difference (P ＞ 0.05).Whether in high or low risk populations,the metastasis and recurrence between dissection group and non-dissection groups showed no significant difference (P ＞0.05).The temporary injury rate of recurrent laryngeal nerve in dissection group were higher than thatin non-dissection group both in high-risk populations (P =0.040,P ＜ 0.05) and low risk populations(P =0.037,P ＜ 0.05).Conclusions Intraoperative frozen pathological diagnosis of papillary thyroid microcarcinoma is difficult.The reasonable surgical approach for the first time is ipsilateral lobe plus isthmus resection.Preventive cervical dissections operation should not be carried out if the exploratory of lymph node showed no metastasis.

Objective To evaluate the clinical efficacy of mesalazine sustained-release tablets in combination with azathioprine in the small intestine Crohn’s disease therapy.Methods 60 cases of small intestinal Crohn disease patients were randomly divided into two groups and the control group 30 cases.Observation group mesalazine sustained-release tablets 1.5 mg ~2.0 mg/( kg? d ) , 1 ~2 times/d, the other in combination with azathioprine 1 g/times, 2 times/d treatment;control group received azathioprine alone 1 g/times, 2 times/d, both groups were treated for 30 weeks after treatment were compared activity index score, clinical remission rate, mucosal healing rate, blood biochemical parameters before and after treatment, and record adverse reactions during treatment.ResuIts The two groups of patients after treatment than before treatment activity index score decreased significantly (P<0.05), but the observation group were more than the control group decreased significantly (P<0.05); observation group complete remission rate and mucosal healing rates better than the control group (P<0.05);the WBC count, ESR and CRP level were lower than before treatment (P<0.05);AIL two levels and TLB levels were significantly increased compared with that before treatment (P<0.01), but the observation group was significantly higher than that in the control group ( P<0.05 ); the incidence of adverse observation group were 26.67%, significantly higher than the 6.67%( P<0.05 ) .ConcIusion Mesalazine sustained-release tablets in combination with azathioprine therapy compared with small bowel Crohn’s disease treatment is more effective azathioprine alone, can significantly improve the therapeutic effect, but incidence of adverse reactions is higher.

The present study was to examine the effect of stellate ganglion block (SGB) on bilateral regional cerebral oxygen saturation (rSO2) and postoperative cognitive function. Eighty patients undergoing selective coronary artery bypass graft with cardiopulmonary bypass (CPB) were randomly and equally divided into two groups. The patients in group S were given right SGB with ropivacaine, while the patients in group C were injected with normal saline. We compared the bilateral rSO2 after SGB. Minimum Mental State Examination (MMSE), Visual Verbal Learning Test (VVLT), and Digital Span Test (DST) were applied to observe the effect on cognitive function. We found that the incidence of postoperative cognitive dysfunction (POCD) 7 days after surgery in group S was lower than that in group C. The level of blocked side rSO₂ of S group were significantly higher before CPB time of rewarming than that before SGB (P < 0.05), much higher than corresponding non-blocked side rSO₂ before CPB (P < 0.05), and much higher than rSO₂ level in group C before CPB and after CPB (P < 0.05). The non-blocked side rSO₂ in group S before anesthesia were much lower than basic levels and those in group C (P < 0.05). It could be concluded from the above results that there was significant increase in the blocked-side rSO₂ compared to the non-blocked side and there was significant decrease in the incidence of POCD compared to the control group after SGB.
