In order to study the curative effects of L arginine (L Arg) on high altitude pulmonary edema (HAPE),we had treated 10 patients with HAPE by intravenous L Arg at 3700m, and the result was compared with 11 patients who inhaled low concentration nitric oxide (NO) and 24 subjects with routine treatment.The findings were as follows:compared with the routine group, inhaling NO or intravenous L Arg could hasten the disappearance of moist rales and X ray shadow, and shorten the illness time( P 0.05). It suggested that intravenous L Arg is a handy way to treat HAPE, and there is no toxicity. It is worthy of further trial.

Objective To explore main risk factors of post-operative severe complications in elderly patients with gastric cancer.Methods From January 2006 to June 2011,a total of 236 elderly patients to receive gastrectomy for gastric carcinoma were retrospectively analyzed in this casecontrol study.The factors affecting post-operative severe complications were analyzed by multivariate logistic regression analysis.Results Age was younger in patients without than those with postoperative complications [(72.9±5.8) years vs.(80.6±6.7) years,t=-9.194,P=0.000].Serum levels of hemoglobin and albumin were higher in patients without than with post-operative complications [(109.94±18.72) g/L vs.(98.75±18.82) g/L,(38.37±5.52) g/L vs.(33.69± 3.35) g/L,t=4.391,7.080,both P=0.000].Operation time was shorter in patients without than with post-operative complications [(3.1 ± 1.0) hours vs.(3.6 ± 1.1) hours,t =-3.507,P =0.001)].Intraoperative blood transfusion volume was less in patients without than with post-operative complications [(2.5±4.4) L vs.(2.8±5.5) L,t=-4.901,P=0.000)].The long diameter of tumor was shorter in patients without than with post-operative complications [(4.5 ± 2.8) cm vs.(5.3± 2.7) cm,t =-2.111,P =0.036)].Logistic regression analysis revealed that chronic obstructive pulmonary disease (COPD),serum albumin level,age,operation time and blood transfusion volume were associated with postoperative severe complications.Logistic regression equation was as follow:P=1/[1+e(16.22-033X1+0.99X3-390X4-192X5-493X9)].Conclusions COPD,operation time,blood transfusion volume,serum albumin level and age are the main independent risk factors for post-operative severe complications in elderly patients with gastric cancer.

Objective To explore the effects of morphine on the terminal of primary afferent fiber distributing in spinal lamina Ⅱ after the sciatic nerve crush. Methods The positive reactive areas of fluoride-resistant acid phosphatase(FRAP) at spinal lamina Ⅱ were measured by the FRAP histochemistry and microcomputer image analysis techniques, after sciatic nerve was injured 15 days and 30 days both in morphine and control groups of rats. Results The positive reactive areas of FRAP at spinal lamina Ⅱ were depleted on different degree in two groups of rat after sciatic nerve was injured. The positive reactive areas of FRAP were greater 40% on injured sciatic nerve in 30 days than in 15 days in control group. In morphine group, the positive reactive areas of FRAP were larger 22% on injured sciatic nerve in 30 days than in 15 days; simulaneously also were bigger 19% than on injured sciatic nerve 30 days of control group.Conclusion The positive reactive areas of FRAP at spinal lamina Ⅱ show recovering enlargement as the surviving time lengthens in both groups of rats injured sciatic nerve.Morphine may enhance the positive reactive area of FRAP at spinal lamina Ⅱ in rat of sciatic nerve crush.

Objective In order to investigate the relationship among reflux esophagitis,Barrett's e- sophagus and esophageal adenocarcinomas,the expressions of Cdx2 and MUC2 gene were studied.Methods Using immunohistochemistry,the expressions of the Cdx2 and MUC2 were detected in the esophageal mu- cosa of 30 patients with reflux esophagitis,18 patients with Barrett's esophagus and 25 patients with esopha- geal adenocareinoma.Results The positive rate and staining intensity of Cdx2 and MUC2 expressions in re- flux esophagitis,Barrett's esophagus and esophageal adenocarcinoma were significantly higher than those in normal esophageal mucosa(P

Objective:To investigate the variations o f mitochondrial D-loop region in gastric cancers. Methods:The D-loop region of 12 gastric cancers together with th e adjacent normal tissues were amplified by PCR and sequenced. Results: Among the 12 cases,16 mutations and 28 polymorphisms were identified with the mutations rate of 50%.There were 3 new polymophisms which we re not reported previously in the GeneBank among the 28 polymorphisms. Conclusion:We think that the mitochondrial DNA D-loop region is a highly polymorphric and mutable region and the mutation rate is relatively high in patients with gastric cancer.

Objective To study the genetics pattern of bronchial hyperresponsiveness and serum total IgE in asthma pedigree. Methods Twenty-eight asthma families were collected, including 124 individuals, 72 with asthma and 52 without. Forty-five normal subjects of three generations without consanguinity among one another, 22 male and 23 female, were chosen as controls, excluding those with family history of asthma and hypersensitivity. Serum total IgE by ELISA and bronchial hyperresponsiveness (BHR) were detected in asthma pedigree members. Genetics pattern of BHR and serum total IgE was analysed. Results The frequency distribution of BHR was bimodal. Individuals with higher level of total IgE occupied 40 of BHR-affected. Conclusion BHR may be controlled by a single major gene. BHR and total IgE may be under separate genetic control.

Combined use of acupuncture and drug is extensively applied for its wide indications,simple manipulation and good results.Combined use of acupuncture and drug is not in effect the mechanic addition of acupuncture and drugs.It has been proved that acupuncture and drug are of synergism,but there may be an antagonism between acupuncture and drug.How to choose the optimum acupoint in the combination of acupuncture and drug to exert better effects is of great theoretical and practical significance for acupuncturists to make further researches.

AIM: To investigate the effect of endotoxin on rat hepatic mitochondria. METHODS: Rats were randomly divided into two groups:endotoxin group and the control. 8 cases of animals were included in each group. The effect of electron leak on the production of endogenous oxygen free radicals and the changes of mitochondria function were studied.RESULTS: Treated with endotoxin, a significant increase in O  2 and the rate of state 3,4 were observed in liver mitochondria; The rate of electron transfer to proton pump of mitochondria respiratory chain complex Ⅱ+Ⅲ( H +/2e -), respiratory control rate and ADP/O decreased significantly. CONCLUSION: A increase in production of endogenous oxygen free radicals induced by endotoxin plays an important role in the injury of rat liver mitochondria.

Abstract: Toxoplasma gondii, an opportunistic pathogenic protozoan, is widely distributed worldwide and can cause zoonoses, which is a serious threat to human health. Nowadays, the relationship between T. gondii infection and neuropsychiatric diseases has attracted researchers' attention increasingly. T. gondii infection is related to the pathogenesis of many neuropsychiatric diseases by affecting the nervous system, such as schizophrenia, depression, Alzheimer's disease, and so on. This review will focus on the relationship between T. gondii infection and neuropsychiatric diseases and summarizes the possible mechanisms of disorders resulting from T. gondii infection． It is expected that the study on the related pathogenic mechanism of T. gondii will lead to new therapeutic directions and feasible solution for the clinical treatment of neuropsychiatric diseases caused by T. gondii infection.

OBJECTIVETo evaluate the early clinical effects of arthroscopic treatment for cruciate ligament cysts of the knee.

METHODSFrom September 2008 to January 2014, 23 patients with cruciate cysts were treated with arthroscopic surgery. There were 11 males and 17 females, with an average age of 28.3 years old (ranged, 16 to 56 years old). Twenty patients had injuries on the right knee and 8 patients had injuries on the left knee. Eight patients had a history of injury,5 patients had a history of chronic injury,and the other 15 patients had no obvious reasons for the symptom. Before the operation, 24 patients were clearly diagnosed as the cruciate ligament cysts of knee joint,and 4 patients were diagnosed as other problems of the knee, but the diagnosis were corrected after the operation. According to the MRI before the surgery,all the patients could be divided into 3 types: 14 were type I, 6 were type II, 8 were type III. After the operation, the patients were suggested to have a rest for 2 weeks, and take exercises everyday at the same time. The knee range of motion, Lysholm score, International Knee Documentation Committee (IKDC) 2000 subjective score, GLASGOW criteria, and McMurray test, pivot shift test, and anterior drawer test were observed to evaluate clinical results.

RESULTSAll the incisions healed at the first stage without complications. Twenty-five patients were followed up, and the duration ranged from 12 to 52 months, with a mean of 26.7 months. Three patients accepted the reconstruction of ACL or tightened elongated ACL using bipolar radio frequency. The Lysholm score increased from preoperative 59.80 +/- 6.58 to 75.32 +/- 6.49 at the latest follow-up; IKDC 2000 score increased from preoperative 65.36 +/- 6.26 to 81.00 +/- 5.76 at the latest follow-up. According to GLASGOW criteria,23 patients got an excellent result and 2 good.

CONCLUSIONIt has a satisfactory curative effect on ACL reconstruction using bipolar radio frequency. It has advantages of firm fixation, simple and secure operation as well as quick postoperative recovery. It's very important to check the MRI before operations, and carefully seek the cysts during the operations, avoiding the omission of any cysts,especially the cases of multiple cysts. Finally, patients should take exercises actively after operations.
