Objective To explore the effect of dexmedetomidine on upper limb surgery during brachial plexus block anesthesia and its influence on cognitive function.MethodsFrom May 2015 to May 2016, 60 cases of elbow joint operation patients were studied.The patients were randomly divided into control group (local anesthesia combined with physiological saline) and observation group (using local anesthesia drugs with dexmedetomidine).The mean arterial pressure and heart rate before and after anesthesia in two groups were compared.The changes of anesthesia and cognitive function, and the incidence of adverse reactions were compared between the two groups.ResultsCompared with before anesthesia, the mean arterial pressure and heart rate were significantly lower in the two groups (P<0.05).The mean arterial pressure and heart rate in the observation group were significantly lower than those in the control group (P<0.05).There was no significant difference between the two groups in the onset time of motor block sensory block, while the observation group was significantly longer than the control group (P<0.05).The control group patients with Ramsay score below 3 points, a total of 4 cases, accounting for the observation group of patients with Ramsay score of less than 3 points, a total of 24 cases, accounting for 80%, the observation group was significantly better than the control group (P<0.05) sedative effect.Compared with before anesthesia, two groups of patients with postoperative 20min MMSE score were lower, but the observation group MMSE score was significantly higher than that of the control group (P<0.05).There was no significant difference in adverse reactions between the two groups.ConclusionIn the following surgery, the use of local anesthesia combined with dexmedetomidine anesthesia can prolong the time of nerve tissue, and can obtain better sedation and pain, and has little effect on the cognitive function of patients.

Objective To explore the association of apoB gene polymorphisms with dyslipidemia and lipid levels in Xinjiang Shihezi Han Chinese. Methods 150 dyslipidemia patients and 150 normal pople were involved in this study. EcoRI and XbaI polymorphisms of apolipoprotein B was analyzed by PCR-restriction fragment length polymorphism. The levels of plasma total cholesterol, triglyceride, low density lipoprotein cholesterol, high density lipoprotein cholesterol, apoAI and apoB were determined. Results The frequency of E + E -/E - E - genotype and E-Allele(37.3% and 19% ) in dyslipidemia group was significantly higher than that in controls( 12. 7% and 6. 3% ). The levels of TC, TG and LDL-C in the E +E -/E - E - gene type were significantly higher than those of the E + E + gene type in each group ( P ＜0. 01 ). The frequency of X + X -/X + X + genotype and X + Allele( 20. 7% and 1 1% ) in dyslipidemia group was significantly higher than that in controls (8% and 4% ). The levels ofTC, TG, LDL-C and apoB in the X + X -/X + X + gene type patients were significantly higher than those in the X - X - gene type patients in every group ( P ＜ 0. 05 ). Conclusion The EcoRI and XbaI polymorphism of ApoB gene was related to dyslipidemia in population of Xinjiang Shihezi Han Chinese, and the E - and X + Allele may be the genetic risk factors for dyslipidemia.

Objective To analyze the risk factors impeding early extubation after off-pump coronary artery bypass grafting (OPCAB) in Chinese patients, so that to identify the applicable patients for "fast track recovery". Methods Clinical data of 680 consecutive patients who had received OPCAB were analyzed retrospectively. The patients were divided into two groups according to the time of extubation (group Ⅰ,n=333, extubation was performed within 12 h postoperation; group Ⅱ,n=347, extubation failed in 12 h). Univariate and multivariate analyses were used to determine risk factors prolonging mechanical ventilation. Results Univariate analyses showed significant difference between the two groups in the percentages of patients over 70 years [25% (84/333) vs 39% (136/347), ?2=15.148, P=0.000], with history of stroke [14% (46/333) vs 22% (75/347), ?2=7.068, P=0.008], with LVEF70 (OR=2.003), LVEF70, severe coronary artery lesion, emergency operation, and poor cardiac function are risk factors impeding early extubation. "Fast track recovery" protocol is applicable to young patients who have good cardiac function without left main lesion and do not need IABP during perioperative period.

Chemotherapy is one of main treatments for nasopharyngeal carcinoma (NPC) except radiation therapy. Improving and optimizing chemotherapeutic regimen are helpful to improve the therapeutic effects and reduce side effects. At present, concurrent chemoradiotherapy still is the standard treatment for advanced nasopharyngeal carcinoma. Induced chemotherapy has been shown superiority, but the effect of adjuvant chemotherapy needs further study. This paper analyzed the superior and inferior, effect and side effect of all kinds of chemotherapeutic methods or scheme including induced chemotherapy, concurrent chemotherapy, adjuvant chemotherapy and palliative chemotherapy and introduced simply the mechanism and clinical effect of new drugs of anticancer. It was hoped to offer some reference for the selection of chemotherapy for NPC.

Objective To Apply appropriate dose of Glutamine(Gln)(300mG/d)for patients with acute cerebral infarction,and observe its preventinG and curinG function to the stress ulcer. Methods Sixty cases patients of acute cerebral infarction were observed and divided into the conventional treatment Group( 30 cases),Glutamine treatment Group( GLU,30 cases). Gastric pH value of patients was tested before treatment and after one week treatment. The stool or vomit occult blood positive( OB+)number of patients within one week, OB( +) duration and the number of patients need blood filterinG were observed. Results There was no siGnificant difference between the conventional treatment Group and the GLU Group in the Gastric juice PH value before treatment(t=0. 647,P>0. 05). After one week treatment,the Gastric juice PH value of the GLU Group was siGnificant hiGher than the conventional treatment Group(t=5. 25,P<0. 05);the number of OB( +)of GLU Group were less than the conventional treatment Group,but there was no statistical siGnificant difference(χ2=0. 577,P>0. 05);the OB( +)duration of GLU Group was less than the conventional treatemnt Group,and there was satistical siGnificant difference(t =4. 768,P <0. 05);the number of blood filterinG of GLU to treat stress ulcer was less than conventional treatment Group,and there was satistical siGnificant difference(χ2=l. 0l6,P>0. 05). Conclusion SupplementinG appropriate dose of Glutamine in patients with acute cerebral infarction can reduce the incidence of stress ulcer,decrease medical expenses.

Generic drug products (test products: drug A, B...) are bioequivalent to an innovator product (reference product) when their bioavailabilities in the same molar dose are similar. Bioavailability is usually expressed by following pharmacokinetic parameters: the area under plasma concentration-time curve (AUC), the maximum plasma concentration (Cmax) and the time of maximum plasma concentration (tmax). This paper used a two period crossover bioequivalence study to develop convenient, friendly user interface software, BA&BE Analysis to statistically process data in clinical pharmacology studies and other areas. The method involves user input of data for analysis into a grid format, setting variables and parameters, followed by one-way analysis of variance (ANOVA), bioavailability and bioequivalence analysis of the data. The software developed in the present study should help scientists to carry out data analysis of bioavailability and bioequivalence testing quickly and easily.

BACKGROUND: There are various reports on studies of tear secretion and tear film function in patients with diabetes mellitus over the past. In recent years, tear proteins have drawn more and more attentions on evaluation of tear film function.OBJECTIVE: To observe the contents of main tear proteins and basal tear secretion of patients with type 2 diabetes mellitus and normal persons so as to probe into tear secretion and tear film function of patients with diabetes mellitus.DESIGN: Case-control observation was designed.SETTING: Department of Ophthalmology, Southwest Hospital, Third Military Medical University of Chinese PLA.PARTICIPANTS: Totally 50 cases (100 eyes) of type 2 diabetes mellitus were employed, which were diagnosed in Department of Ophthalmology and Department of Endocrinology, Southwest Hospital of Third Military Medical University of Chinese PLA from December 2001 to December 2002. They were free from ocular surgical and laser treatment, local medication in recent period and contact lens. Of those, there were 25 cases (50 eyes) in proliferating diabetic retinopathy group and 25 cases (50 eyes) in nonproliferating diabetic retinopathy group. In addition, 25 cases (50 eyes) of normal persons with matched age and sex were taken as the control group.There was no significant difference in age and sex among 3 groups (x2=0.024,0.321 ;P ＞ 0.05). All of the participants were in the know before the experiment.METHODS: [1] Tear collection: 10 cases (20 eyes) were randomized from two diabetic groups and the control successively. Capillary pipette method was used to collect non-irritative tear 10 μL from lower lacrimal punctum that was preserved in refrigerator at -20 ℃ (＜ 1 month). [2] Determination of total tear protein amount: Lorry method was used to determine the concentration of total tear protein, in which, calf serum albumin was taken as the criteria. [3] Determination of contents of main tear proteins: SDS-PAGE (sod.dodecyl sulfate-polyacrylamide gel electrophoresis) was used and Coomassie brilliant blue staining and Bio-Rad imaging analyzing system were applied for the analysis of isolated protein strips in quality and quantity. [4] Determination of rupture time of tear film: glass rod was used to get 20 g/L fluorescein sodium and drop in conjunctival sac. The examined person was required to blink gently for several times and open the eyes naturally and stare forward. That the first ruptured "black hole" was discovered on the complete tear film was taken as the rupture time of tear film. [5] Experiment of basal tear secretion: No.41 Whatmann filtering paper was used, folded in 5 mm, and placed at 1/3 of conjunctiva in the lower eyelid. Five minutes later, the paper was removed and length of it after wetting was measured. [6]Experiment with rose Bengal staining: glass rod was used to get 10 g/L rose Bengal and drop in conjunctival sac. After eyes blinking for several minutes, the observation was performed with green light filter under slit lamp (evaluation criteria: corneal conjunctiva of palpebral fissure stained+, stained to the inferior bulbar conjunctiva++,stained to the superior bulbar conjunctiva). Dry eye disease was diagnosed indirectly with red-stained epithelial cells and mucin.MAIN OUTCOME MEASURES: [1] Concentration of total tear protein. [2]Concentrations of various main tear proteins. [3] Rupture time of tear film. [4]Value of basal tear secretion. [5] Positive rate of rose Bengal staining.RESULTS: Totally 50 cases (100 eyes) in diabetes groups and 25 cases(50 eyes) in the control group all entered result analysis. [1] Concentration of total tear protein: there was no significant difference among 3 groups (P＞ 0.05). [2] Concentrations of various main tear proteins: the results of lysozyme, lactoferritin and tear specific prealbumin in proliferating diabetic retinopathy group were lower remarkably compared with the control[ (0.94±0.21)vs ( 1.33±0.31 )g/L , ( 1.10±0.24)vs ( 1.67±0.43 )g/L, (0.98±0.22) vs (1.49±0.32)g/L, P ＜ 0.01]. Compared with non-proliferating diabetic retinopathy group, the results of lactoferritin and tear specific prealbumin were lower (P ＜ 0.05). There was no significant difference in human serum albumin among 3 groups (P ＞ 0.05). [3] Rupture time of tear film:compared with non-proliferating diabetic retinopathy group and the control, the rupture time of tear film in proliferating diabetic retinopathy group was reduced significantly [(7.68±2.21)s vs (9.92±2.37)s and(10.80±2.23)s,(P ＜ 0.01 )]. [4] Value of basal tear secretion: the value in proliferating diabetic retinopathy group was less significantly than that in non-proliferating diabetic retinopathy group and the control [ (8.00±2.10)vs( 11.02± 1.97 )mm and ( 12.17±2.08 )mm, P ＜ 0.05]. [5] Positive rate of rose Bengal staining: the positive rate in proliferating.diabetic retinopathy group was higher significantly than non-proliferating diabetic retinopathy group and the control (48% vs 24% and 14%, P ＜ 0.05, P ＜ 0.01).CONCLUSION: It is suggested in the results of this paper that abnormal tear secretion and tear film function are apt to present in patients with type 2 diabetes mellitus and the declined tear film function is more remarkably in the patients with proliferating diabetic retinopathy specially. SDS-PAGE benefits the discovery of changes in tear proteins in diabetic patients.
