Objective To investigate the effects of sevoflurane preconditioning on the expression of pulmonary angiotensin converting enzyme (ACE) mRNA in lung tissues during lung ischemia-reperfusion (I/R) in rats.Methods Fifty-four male Sprague-Dawley rats,weighing 250-320 g,were randomly divided into 3 groups (n =18 each):sham operation group (group S),I/R group and sevoflurane preconditioning group (group SP).The animals were anesthetized,tracheostomized and mechanically ventilated.Lung I/R was induced by clamping the left pulmonary hilum for 45 min followed by 120 min reperfusion in groups I/R and SP.While the left pulmonary hilum was only isolated but not ligated in group S.2.1％ sevoflurane was inhaled for 30 min,and lung I/R was induced 10 min after the end of inhalation in group SP.Six rats in each group were chosen at 30,60 and 120 min of reperfusion and sacrificed,lungs were removed for determination of wet/dry lung weight (W/D) ratio,MPO activity (by colorimetric method) and the expression of ACE mRNA (by RT-PCR) and for microscopic examination in lung tissues.Results Compared with group S,the W/D ratio,MPO activity and expression of ACE mRNA were significantly increased in groups I/R and SP (P ＜ 0.05).Compared with group I/R,the W/D ratio,MPO activity and expression of ACE mRNA were significantly decreased in group SP (P ＜ 0.05).Microscopic examination showed that the pathologic changes were significantly attenuated in group SP compared with group I/R.Conclusion Sevoflurane preconditioning can reduce lung I/R injury through downing-regulating the expression of ACE mRNA in rats.

OBJECTIVE:To observe the clinical efficacy and safety of sodium hyaluronate combined with glucosamine in the treatment of knee osteoarthritis. METHODS:1 220 patients with knee osteoarthritis were randomly divided into observation group and control group. The patients in control group were treated with Sodium hyaluronate injection alone,once a week;while the ob-servation group was additionally and orally treated with Glucosamine hydrochloride capsules two tablets,three times a day. The course of treatment was 5 weeks in both groups. The relevant physicotherapeutics and oral medication in the treatment of the dis-ease should be stopped. The clinic efficacy,visual analog scale(VAS)and lysholm knee score before and after treatment,and inci-dence of adverse reaction were observed. RESULTS:Total effective rate of observation group was significantly higher than control group,with statistically significant difference(P<0.05). After treatment,VAS and lysholm knee scores in both groups were signifi-cantly lower than before,and observation group was lower than control group,with significant differences(P<0.05). There were no severe adverse reactions during treatment. CONCLUSIONS:Sodium hyaluronate combined with glucosamine has more signifi-cant clinical efficacy in the treatment of knee osteoarthritis than sodium hyaluronate alone,with good safety.

Objective To study the relationship between the diabetic autonomic neuropathy (DAN) and the cerebrovascular disease. Methods The heart rate variability (HRV) was measured in 77cases of type 2 diabetes 〔49 men, 28 women, age (63.1?11.4)years〕. Forty-one cases suffered from DAN (group A), 36 cases without DAN (group B) according to the results of HRV. All the cases received the examination with transcranial Doppler ultrasonography (TCD). Results Compared with group B, the abnormality detected with TCD was higher in group A, cerebrovascular compliance was commonly decreased and cerebrovascular stenosis was also extensively observed. Conclusion DAN seems to be one of the risk fcators in inducing cerebrovascular disease.

Objective To study the levels of bone alkaline phosphate (BALP) in healthy children in the specific hospital.Methods Totally 990 healthy children from 0-16 years old were selected,all of whom received physical examination in the Xiasha branch of Zhejiang Provincial Hospital of TCM during August 2013 to April 2014.Serum was collected and tested for BALP levels with a Beckman Coulter Immunoassay System UniCel DxI 800.Z-test was used to verify age and gender grouping,after which the 2.5th and 97.5th percentile values of serum BALP levels were calculated.Results The levels of serum BALP(bilateral 95％ range) in healthy children were as follows:trottie stage (0-1 years old):37-300μg/L;infancy to school stage (＞ 1-9 years old):40-196 μg/L;puberty stage (＞9-16 year-old):25-284 μg/L (male),30-199 μg/L (female).The serum BALP levels of male children showed a weak correlation with height,while the correlation for female children was not significant.Conclusions The levels of BALP in healthy children of the specific hospital and area were established.Serum BALP levels in children varied with age and sex.

Objective To investigate the effects of remifentanil on lung ischemia-reperfusion (I/R) injury and expression of angiotensin-converting enzyme (ACE) mRNA in rats.Methods Forty pathogen-free adult male Sprague-Dawley rats,weighing 300-350 g,were randomly divided into 5 groups (n =8 each):sham operation group (group S),group I/R and different doses of remifentanil groups (groups R1-R3).Lung I/R was produced by occlusion of the left hilum of lung for 45 min followed by 120 min reperfusion.Remifentanil was infused intravenously at a rate of 0.2,0.6 and 1.2 μg·kg-1 ·min-1 until 120 min of reperfusion after a loading dose of 1 μg/kg at 15 min before occlusion of the left hilum of lung in groups R1,R2 and R3,respectively.The equal volume of normal saline was given in groups S and I/R.The rats were scarified at 120 min of reperfusion and lungs were removed for microscopic examination and determination of wet/dry lung weight ratio (W/D ratio) and the expression of ACE mRNA (by RT-PCR) in the lung tissue.The pathological changes of the lung were scored.Results Compared with group S,the pathological score and W/D ratio were significantly increased and the expression of ACE mRNA was up-regulated in groups I/R,R1 and R2,and the pathological score was significantly increased (P ＜ 0.05),and no significant change was found in W/D ratio and the expression of ACE mRNA in group R3 (P ＞ 0.05).Compared with group I/R,the pathological score and W/D ratio were significantly decreased and the expression of ACE mRNA was down-regulated in groups R2 and R3,and the pathological score and W/D ratio were significantly decreased (P ＜ 0.05) and no significant change was found in the expression of ACE mRNA in group R1 (P ＞0.05).Compared with group R1,the pathological score and W/D ratio were significantly decreased and the expression of ACE mRNA was down-regulated in group R3,and the pathological score and W/D ratio were significantly decreased (P ＜ 0.05) and no significant change was found in the expression of ACE mRNA in group R2 (P ＞ 0.05).The pathological score,W/D ratio and expression of ACE mRNA were significantly lower in groups R3 than in group R2 (P ＜ 0.05).The pathological changes of the lung were significantly reduced in groups R1-R3 as compared with group I/R.Conclusion Remifentanil can attenuate lung I/R injury in rats in a dose-dependent manner and down-regulation of ACE mRNA expression may be involved in the mechanism.

OBJECTIVETo compare the clinical therapeutic effects on intractable facial paralysis among acupuncture, acupoint catgut embedding and PDS embedding.

METHODSTwo hundred and seventy-nine patients of intractable facial paralysis were randomized into an acupuncture group, a catgut embedding group and a PDS embedding group, 93 cases in each one. Cuanzhu (BL 2), Yuyao (EX-HN 4), Taiyang (EX-HN 5), Xuanlu (GB 5), Dicang (ST 4), Jiache (ST 6), Quanliao (SI 18), Qianzheng (Extra), Xiaguan (ST 7) and Fengchi (GB 20) on the affected side and bilateral Hegu (LI 4) and Zusanli (ST 36) were selected in the three groups. In the acupuncture group, acupuncture was applied to those acupoints, once every two days; 10 treatments made one session; the successive three sessions were required. In the catgut embedding group and the PDS embedding group, catgut and PDS were embedded separately, once every 10 days; 3 treatments made one session and the successive two sessions were required. The therapeutic cycle was 2 months in the three groups. The therapeutic results were analyzed statistically 2 months later. The scores of Sunnybrook facial nerve grading system and the facial nerve electroneurography (ENoG) were used for the efficacy assessment before and after treatment in the three groups.

RESULTSAfter treatment, the score of Sunnybrook facial nerve grading system was improved apparently after treatment as compared with that before treatment in any of the three groups (all P < 0.05). The score in either of the embedding groups was better than that in the acupuncture group (both P < 0.05). The difference was not significant between the catgut embedding group and the PDS embedding group (P > 0.05). After treatment, ENoG wave ampli tude values in the frontal muscle and orbicularisoris muscle on the affected side were improved as compared with those before treatment in the three groups (all P < 0.05). Those in the catgut embedding group and the PDS embedding group were better than those in the acupuncture group (all P < 0.05), and had no significant difference as compared with those on the healthy side (P > 0.05). In the acupuncture group, ENoG wave amplitudes on the affected side were lower than those on the healthy side (both P < 0.05).

CONCLUSIONAcupuncture, catgut embedding and PDS embedding at acupoints all achieve the therapeutic effects on intractable facial paralysis. However, the acupoint embedding therapy presents more advantages on the recovery of facial nerve function. The efficacy is similar between the catgut embedding and the PDS embedding.

Isoprene is an important precursor of synthetic rubber material. In our previous study, metabolic engineered Escherichia coli strain (BW-01) was constructed and used to produce isoprene. Based on the theory of protein budget, using synthetic biology strategies including the increased copy number of genes and rare codons, we regulated the expression of key enzyme to improve isoprene production in Escherichia coli strain. Under shake-flask conditions, isoprene productivity of the engineered strain (BW-07) increased by 73% compared with BW-01, reached 761.1 mg/L. It provides a reference for further studies.

Objective To investigate whether nimodipine could reduce complications after microvascular decompression in patients with hemifacial spasm. Methods 220 patients with hemifacial spasm , admitted into our hospital from May 2011 to Oct. 2013 , were all treated by microvascular decompression. They were divided randomly into two groups. Patients in the treatment group were treated with nimotop 50 mg/d after the operation for the first 3 days, then was orally taken 30 mg/d for a week. Patients in the control group were treated with the same after the operation without nimodipine. The postoperative complications including hearing deficit and peripheral facial paralysis were closely observed within three months after operation. Results The total effective rate was 100% in both groups. The incidence rate of peripheral facial paralysis and hearing deficit in treatment group was significant lower than that of the control group (P < 0.05). Conclusion Nimodipine has significant effect on reducing the incidence rate of peripheral facial paralysis and hearing deficit after microvascular decompression in patients with hemifacial spasm.

Objective To investigate the clinical effect of azithromycin on ankylosing spondylitis (AS). Methods Sixty-four AS patients with active disease were enrolled in this study. Among them, thirty-two AS patients (treatment group)received Azithromycin treatment at a dose of 0.5 g once a day for a period of 5~7 days , and another thirty-two patients receiving conventional treatment served as control (control group). BASDAI, CRP and ESR served as the disease activity evaluation index. Results Activity indexes in two groups of in the first 4~ 20 weeks of the treatment were decreased compared with those before the treatment (P < 0.05), while a rise was found in the 20 ~ 24 week and activity indexes gradually returned to pretreatment levels. At 0 ~ 16 weeks , the disease activity index of treatment group was below normal levels but that of control group was higher than the normal level with significant difference (P < 0.05). Conclusion The treatment of Azithromycin can control the disease activity of AS in the long term, which would be a new proposal in AS treatment.
