Objective To evaluate the relationship between glycemic control and lipid profile in patients with type 2 diabetes.Methods The patients with type 2 diabetes taking oral antidiabetic agents only were investigated for their levels of blood glucose and lipid profile.With a standard for valid blood glucose control( HbA1c <7% ),the patients were divided into two groups,reached the goal group and not reached the goal group,and the lipid profile was compared between the two groups.Results Completed study had been obtained 173 patients,average HbAlc,7.9%,total success rate of glycemic control,with 43.4% being the figure reported.We can see a lower triglyceride( TG),total cholesterol (TC) and low density lipoprotein cholesterol(LDL-C) level and a higher high density lipoprotein cholesterol (HDL-C) level in the group reaching the stantard ( t =- 2.437,- 2.067,2.005,- 2.984,P =0.016,0.040,0.047,0.003).Conclusion The blood lipid profile should be considered while the level of glucose of patients with type 2 diabetes taking oral antidiabetic agents alone are controlled.

Corydalis Rhizoma, the dried tuber of Corydalis yanhusuo (Papaveraceae) distributed traditionally mainly in south-eastern and now cultivated in northwestern and other district in China, is one of the commonly used and well-known traditional Chinese medicine. It has been widely used to treat spastic pain, abdominal pain, pain due to injury, and promote blood circulation. Its main chemical constituents were alkaloids, which were divided into the two types of protoberberines and aporphines. Among them, some alkaloids were found to elicit profound effects on the dopaminergic system in the central nervous system, which plays an important role in regulating nociception. In this article, the chemical composition and structure-types, new methods of qualitative and quantitative analysis as well as characteristics of biotransformation, absorption, distribution, metabolism, excretion, pharmacokinetic, and drug-drug interaction for the alkaloids were revealed. These results would greatly contribute to the establishment of bioactive material base of Corydalis Rhizoma.

ObjectiveTo explore the renal functions of vasopressin-deficient Brattleboro(BB) rats by using different concentrated Gadolinium-diethylenetetramine pentaacetic acid(Gd-DTPA) dynamic enhanced magnetic resonance imaging(MRI).MethodsThe study included 14 BB rats(male rats of 3 month-old) and 14 normal male Wistar rats used as control group.Dynamic MRI was performed by using either a low dosage(0.05 mmol/kg) or a high dosage of Gd-DTPA(0.5 mmol/kg).Data of 0-60 min renal cortex,medulla and pelvic were obtained after using contrast medium.MRI of kidneys at different time was analyzed and the mean relative signal intensity(RSI) was measured.Then the RSI curves of different groups were marked.Data of each group were caculated separately by SPSS 11.0 software.ResultsThe findings demonstrated that RSI curves of the vasopressin-deficient kidneys showed different patterns as compared with those of the control group(P

Objective:To summarize the experiences of the surgical treatment of tumors in the posterior part of the third ventricle and pineal region. Methods: Twenty-seven patients with tumors in this region treated microsurgically from 1990 to 2000 were analyzed. The surgical indications, approaches, and operative key points were discussed. The prognostic factors were also analyzed. Results:Tumors were removed totally in 11 patients, removed subtotally in 7 and removed partially in 5. Biopsy and ventriculo-peritoneal shunt was performed in 4 patients. Of 17 patients in follow-up, 13 patients survived longer than 5 years. Conclusions: Most tumors in the posterior part of the third ventricle and pineal region can be surgically removed.Sufficient specimen obtained in the operation can confirm pathologic property of the tumor,guiding next chemotherapy and radiotherapy.

OBJECTIVETo comparatively observe the curative effect, adverse reaction and compliance of Modified Xiaoyao Pill combining amitriptyline (MXP-At) in treating patients with depression.
METHODSSixty-four patients with diagnosis of depression matched to the Chinese Classification of Mental Disorders (CCMD-3) were randomly assigned to 2 groups, the treatment group treated with MXP-At and the control group with fluoxeline, 32 cases in each group. The curative effect was evaluated by Hamilton depression (HAMD) scale and the adverse reaction was recorded before treatment and at the 2nd, 4th and 12th week of the treatment. Patients were regularly followed up from the 12th week to the 24 th week. The curative effect and compliance in the two groups were compared.
RESULTSThe HAMD score dropped in both groups from the 2nd week of the treatment, and at that time, it was lower in the control group than that in the treatment group (P < 0.05); but at the 4th week, no significant difference was found in the therapeutic effect and the HAMD score between the two groups. However, 3 and 14 cases in the treatment and the control group were relapsed during the 12 weeks of follow-up respectively.
CONCLUSIONMXP-At shows a curative effect similar to fluoxetine on depression but with less adverse reaction, and is not expensive.

OBJECTIVETo establish a method for rapid determination of airborne acrylonitrile using a portable gas chromatograph.
METHODSA single standard sample of acrylonitrile was prepared in a laboratory and sampled by the built-in constant flow pump of the portable gas chromatograph. The sample was then preconcentrated by the preconcentrator, thermally desorbed, separated by capillary columns, and detected by a micro argon ionization detector to determine the retention time. Retention time was then used to perform qualitative analysis. Under the set condition of gas chromatography, the external standard method was used to create a standard curve for quantitative analysis of acrylonitrile.
RESULTSThe linear range of acrylonitrile on the portable gas chromatograph was 0.25 to 3.00 mg/m(3). The regression equation was y = 10(-5) x-0.0275, r = 0.9977. The limit of detection was 0.005 mg/m(3), and the lower limit of quantification was 0.25 mg/m(3). The relative standard deviation was lower than 7.09%, and the degree of accuracy was 91.09-105.54%.
CONCLUSIONPortable gas chromatography is a simple, repeatable, and accurate method for rapid determination of airborne acrylonitrile.

BACKGROUND:There is no literature about the treatment according to the mechanism of cervical spine injury classification, especial y for the treatment of extension type cervical fracture/dislocation with merger cases of posterior composite structure damage, whether simple anterior approach can meet the needs of the treatment has no detailed elaboration. This article may analyze from the aspect of cervical spine injury mechanism. OBJECTIVE:To observe the short-term effect of anterior cervical Cage-assisted fusion combined with locking titanium plate internal fixation for the treatment of extension type cervical fracture. METHODS:A retrospective analysis was performed in 15 extension type cervical spine fracture dislocation patients treated with decompression anterior cervical intervertebral disc resection plus bone graft with cage-fusion locking titanium plate internal fixation from June 2006 to March 2011 in the Department of Orthopedics, Xianning Central Hospital, including 10 cases of single segment injury and treatment, and five cases of multiple segment injury and treatment. Japanese Orthopaedic Association score and the neck disability index were compared before and after treatment;the cervical flexion and height were measured according to the antersposterior X-ray film taken before fixation, 1 week after fixation and final fol ow-up.RESULTS AND CONCLUSION:The patients were fol owed-up for 8-37 months. One case had Cage mild sinking and shift, and there was no internal fixation breakage or loosening in al the patients. Transient pharyngeal discomfort was observed in 11 patients. Compared with the preoperation, the Japanese Orthopaedic Association score, neck dysfunction index, fusion segment cervical flexion and fusion segment intervertebral disc height were significantly improved at 1 week after fixation and final fol ow-up (P<0.05). There were no significant differences between 1 week after fixation and final fol ow-up (P>0.05). The short-term effect of decompression anterior cervical intervertebral disc resection plus bone graft with cage-fusion locking titanium plate internal fixation for the treatment of extension-type cervical fracture is good.
