Objective To observe the changes of serum interleukin and T lymphocyte subsets levels in patients with gallstones before and after treatment. Methods 72 patients with gallstones were treated as research subjects and 30 cases with normal physical examination as the control group,the serum interleukin and T lymphocyte subsets levels of observation group were detected before and after surgery. Results The preoperative serum IL-6, IL-8 and TNF-α levels of observation group were(61.5 ±4. 8) ng/L, (246. 2 ±15.3)ng/L and(1.79 ±0.72)mg/L respectively which were significantly higher than postoperative and control group,the difference was statistically significant (P ＜ 0. 05 ) , while there was no significant difference between postoperative and normal control group ( P ＞ 0.05); The preoperative CD3+ , CD4+ and CD8+ T cells ratio of observation group were (0. 53 ± 0. 06) % , (0. 28 ±0.05)% and(0.21±0.04)% respectively which were significantly higher than postoperative and control group,the difference was statistically significant(P ＜ 0.05) , while there was no significant difference between postoperative and normal control group(P＞0.05). Conclusion Patients with gallstone had obvious abnormal serum IL-6, IL-8, TNF-α,CD3+ ,CD4+ and CD8+ T cells levels,surgery could not only eliminate inflammation,but also help the recovery of immune function in patients.

OBJECTIVE:To observe the efficacy and safety of vitamin B12 combined with mouse nerve growth factor in the treatment of neurogenic tinnitus. METHODS:270 patients with neurogenic tinnitus were randomly divided into control group 1, control group 2 and observation group. Control group 1 was treated with Vitamin B12 injection 25 μg by intramuscular injection, once a day;control group 2 was treated with mouse nerve growth factor 18 μg adding into 2 ml water for injection for dissolution, once a day;observation group was treated with Vitamin B12 injection 25 μg(the usage was the same as control group 1)+mouse nerve growth factor 18 μg(the usage was the same as control group 2). 6 d was a treatment course,and it lasted 2 courses. Clinical efficacy,and sleep SPIEGEL score and incidence of adverse reactions before and after treatment in 3 groups were observed. RE-SULTS:Total effective rate in observation group was significantly higher than control group 1 and control group 2,the difference was statistically significant (P<0.05);however,there was no significant difference between control group 1 and control group 2 (P>0.05). After treatment,sleep SPIEGEL score in 3 groups was significantly higher than before,and observation group was high-er than control group 1 and control group 2,the difference was statistically significant(P<0.05);however,there was no signifi-cant difference between control group 1 and control group 2(P>0.05). There were no obvious adverse reactions during treatment. CONCLUSIONS:Vitamin B12 combined with mouse nerve growth factor has better efficacy than only vitamin B12 or mouse nerve growth factor in the treatment of neurogenic tinnitus,with good safety.

AIM: To study the distribution, location and quantity of myocardial collagen(Col) in different phases after myocardial infarction(MI). METHODS: The method of immunohistochemical technique combined with automatic image analysis was used to investigate the changes of collagen Ⅰ and Ⅲ. RESULTS:Contents of Col Ⅰ, Col Ⅲ and the ratio of Ⅰ/Ⅲ were all increased in infarcted area (IA)after MI,and the increase of Col Ⅰ was higher, the collagen fibers still construct a network in acute phase, in chronic stage, all necrosis myocytes were replaced by collagen, the fibers were dense, and paralelled with cardiac cavity surface.In the septum,noninfarcted area, contents of collagen type Ⅰ and Ⅲ, the ratio of Ⅰ/Ⅲ were increased.In acute phase, the increase of type Ⅲ is dominant,with in chronic phase, type Ⅰ is. Right ventricle(RV) has no significant change in acute phase,untill chronic phase,it changed like septum,the increase in collgen is mainly type Ⅰ. CONCLUSION: The collgen remodeled after myocardial infarction were reparative fibrosis in IA phase, and reactive fibrosis in NIA phase. Remodeling occured later in RV than in septum.

Cerebral ischemia and reperfusion can cause delayed neuronal death in rodents,such as Mongolian gerbils and stroke-prone spontaneously hypertensive rats(SHRSP),which are used as an experimental stroke model.The protective effects of antioxidant nutrients such as vitamin E,green tea extract,ginkgo biloba extract,resveratrol,niacin and isoflavones in cerebral ischemia and reperfusion brain injury were reviewed.

The matrix metalloproteinases(MMP) are important enzymes that regulate developmental processes,maintain normal physiology in adulthood and have reparative roles in specific stages after an insult to the nervous system.Conversely,the concordant presence and significant up-regulation of several MMP members in virtually all neurological conditions result in pathological lesions.Thus,the MMPs have double functions,capable of mediating repair and recovery on the one hand and being involved in producing injury on the other.This article highlights the beneficial roles of MMP-2 and MMP-9 in normal and reparative processes within the nervous system and discusses the detriments of both encountered in spinal cord injury and central nervous system cancers,and we also review the availability of MMP inhibitors for clinical use.

OBJECTIVE To observe the clinical characteristic of broanchopulmonary Candida infection in acute exacerbations of chronic obstructive pulmonary disease(AECOPD).METHODS To analyze retrospectively 50 broanchopulmonary Candida infection patients with AECOPD.RESULTS From fungal infections the Candida infection occupied 56.82%.The risk factors were included: using long-term antibiotic,hypoproteinem,mechanical ventilation and complicated with diabetes or cardiovascular diseases.There were Candida albicans(56.52%),C.tropicalis(20.29%),C.parapsilosis(14.49%) and C.krasei(8.69%),after getting the microbiology result by bronchoalveolar lavage under fibrobronchocope,cultivating deep part sputum,brushing biopsy on broncho mucous membrane,lung biopsy,and cultivating blood and pleural effusion,and to think highly of preempting treatment and using medicine by fungi category and cultivating result.CONCLUSIONS The Candidia are the main pathogens in AECOPD;it is better using the local and systemic medicines in combination.

Objective To study the effect of minimally invasive surgery for treatment of cholecystolithiasis together with common bile duet stones.Methods 245 patients suffered from common bile duct stones were admitted and received the therapeutical procedures.All patients were randomly divided into two groups.138 patients in the treatment group treated with minimally invasive surgery;107 patients in the control group treated with the traditional way of laparotomy.Results Compared with the control group,the treatment group showed high cure rate of 97.83%(P＞0.05),low complication rate of 5.19%,short hospital stays of(7.5±2.1)d,less cost of(8 134±1 676)CNY (x2=18.34,t=8.75,6.93,all P＜0.01).Conclusion Minimally invasive surgery had more advantages and wide application for both doctors and patients.

Objective To investigate the effect of hypobaric hypoxia postconditioning( HHP) on neurological func-tion prognosis in traumatic brain injury( TBI) rats. Methods 48 adult male Wistar rats were randomly divided into sham group(n=12),fpi group(n=18) and HHP group(n=18). The rat model of TBI was made by the method of fluid percussion injury( FPI) and rats in HHP group were submitted to HHP(360 Torr,2 h,3 trails spaced at 24 h) starting 3 h after FPI. The learning and memory abilitiy,motor coordination,anxiety and depression-like behaviors and surviving neurons of ipsilateral hippocampus were evaluated by Morris water maze( MWM) ,rotatord test,open-field test and hippocampus nissl stain respectly. Results Morris water maze:compared with sham and HHP group, learning and memory abilitiy of rats in fpi group were significantly decreased(F=4. 257 6,P<0. 05),whereas no difference was observed between sham and HHP group(P>0. 05);Rotatord test:compared with sham group,motor coordination of rats in HHP group were significantly decreased ( F=4. 335 , P<0. 05 ) , whereas no difference was observed between sham and fpi group ( P >0. 05 );Open-field test:compared with sham group, rats of fpi group showed significant anxiety and depression-like behavioral changes, whereas no difference was observed between sham and HHP group;Nissl stain:No difference of surviving neurons of ipsilateral hippocampus CA1 and CA3 re-gion was observed among three gourps at 3 d after FPI(P>0. 05). There were significantly fewer surviving neurons of ipsilateral hippocampus CA1 and CA3 region in fpi group than sham and HHP group at 24 d after FPI ( F =46. 758,5. 486,P<0. 05). Conclusion TBI induces learning and memory impairment,anxiety and depression-like behaviors and neurons death in hippocampus. HHP was first discovered having double effects on neurological func-tion prognosis in TBI rats. On the one hand,HHP can remove the impairment of learning and memory,anxiety and depression-like behaviors and neurons death in hippocampus;on the other hand,HHP impairs motor coordination at the same time.
