The practice and exploration of bilingual teaching for the course of microbiology has been made in order to improve the students foreign lingual level and to meet the higher requirement on tip-top person with the social development. As a result,bilingual teaching is welcome,and the teaching effect is so distinct that the aim was reached to either study the fundamental knowledge or enhance the English level.

Forest musk deer (Moschus berezovskii), a rare wild medicinal animal, is listed under the category of the state key protected wildlife list of China. Musk, secreted by the musk glands, is with high economic and medicinal value and used as precious traditional medicine in China. In order to meet the needs of musk in Chinese traditional medicine, forest musk deer farming was conducted in 1950s, but the research progress on musk secretion mechanism was slow. Therefore, by reviewing the histological and anatomical structure of forest musk deer musk gland, the relationship between sex hormones and the musk secretion process, and the molecular mechanism of the musk secretion, the existing problems in investigating the musk secretion mechanism were analyzed and the development trends in this field were also discussed, in order to provide a reference for further studies on the musk secretion mechanism and improve musk production of forest musk deer.

OBJECTIVETo analyze the mortality trends and disease burden of malignant tumors in rural area of Feicheng city from 2000 to 2010, and to provide basic information for the prevention and treatment of malignant tumors in this area.

METHODSThe data of cancer mortality from 2000 to 2010 from Feicheng Cancer Registry database were checked. Mortality rate, standardized mortality rate, potential years of life Iost (PYLL), standardized potential years of life lost (SPYLL), average years of life lost (AYLL) and other indexes were calculated and analyzed. The trend of the standardized rates transformed by the natural logarithm over time was assessed by Prais-Winsten regression method in which the errors was assumed to follow a first-order autoregressive process. STATA 12.0 was used to analyze the data.

RESULTSIn average, the crude mortality rate was 199.67 per 100 000 (264.69 per 100 000 in males and 137.24 per 100 000 in females), and the standardized mortality rate was 157.00 per 100 000 (200.49 per 100 000 in males and 101.31 per 100 000 in females). There were no significant changes in the trends of all standardized rates. For males, the mortality rates of lung and colorectal cancers increased significantly, and for females, the rates of lung and breast cancers had increased trend while the rate of esophageal cancer showed a downward trend. There were no statistically significant changes in other main malignant tumors. During 2000 to 2010, the PYLL of malignant tumors in Feicheng was 183 685.0 person-years, and PYLL rate was 23.3 per 1000. The SPYLL was 153 091.0 person-years, SPYLL rate was 19.4 per 1000, and AYLL was 14.8 years.

CONCLUSIONSThere are no obvious changes in the trends of standardized mortality rates in rural area of Feicheng over the past 11 years. For males, the mortality of lung cancer and colorectal cancer is increasing, and for females, the rates of lung and breast cancers have an increasing trend while the rate of esophageal cancer shows a decreasing trend. The prevention and control of digestive malignant tumors, lung cancer and breast cancer are getting seriously important and should be the focal point in this issue.

OBJECTIVETo evaluate the clinical application of susceptibility-weighted magnetic resonance imaging (SWAN) in lacunar cerebral infarction imaging.

METHODSForty-two cases of lacunar cerebral infarction, including 18 complicated by high blood pressure, 4 by type 2 diabetes and 12 by both high blood pressure and type 2 diabetes, underwent examinations with SWAN and conventional MRI sequences (including GRE sequence T(1) and T(2), T(2) gradient echo, T(2) FLAIR, DWI). The imaging data were analyzed in comparison with the clinical data of the patients.

RESULTSIn 23 patients with lacunar cerebral infarction, intracerebral micro-hemorrhage displayed point-like, round and oval low signal on SWAN. A total of 123 lesions were identified, distributing from the cortical, subcortical, basal ganglia, thalamus, brain stem to the cerebellum. The conventional sequences were more sensitive in detecting the majority of lacunar cerebral infarction than SWAN, while the latter showed better performance in displaying cerebral micro-hemorrhage, tiny blood vessels and small vascular malformations as well as other small vascular diseases. SWAN was superior to other sequences in showing lacunar cerebral infarction complicated by cerebral micro-hemorrhages.

CONCLUSIONMRI SWAN can better display lacunar cerebral infarction associated with cerebral micro-hemorrhages and small veins in the infract region. Identification of the micro-hemorrhages in lacunar cerebral infarction can be critical in determining the proper treatments. Patients with lacunar cerebral infarction are likely to have cerebral micro-hemorrhages in close relation to the number of lacunar infarction sites. The cerebral micro-hemorrhages and lacunar cerebral infraction are both signs of micro-vessel damage of the brain.

OBJECTIVETo compare the short-term outcomes in patients with esophageal cancer after subtotal esophagectomy via thoracoscopy in prone position and in left lateral position.

METHODSBetween September 2008 and September 2010, thoraco-laparoscopic esophagectomy (TLE) with thoracoscopic mobilization of the esophagus and mediastinal esophagectomy was performed in 41 patients in prone position (group A) and other 41 patients (group B) performed by the same surgeon in left lateral position.

RESULTSPreoperatively, the endoscopic location of the tumor was in the upper third in 5 cases (2 vs. 3), the middle third in 21 cases (12 vs. 9), and the lower third in 56 cases (27 vs. 29). The median operative time was 230 (range 170-310) min in group A and 280 (range 190-380) min in group B (P=0.04). The median intraoperative blood loss was 275 (range 100-320) ml in group A and 360 (range 120-670) ml in group B (P=0.09). The median number of lymph nodes dissected was 8.4 (range 4-23) in group A and 6.9 (range 6-21) in group B (P=0.03). The postoperative complications totaled 6 (14.6%) in group A and 8 (17.1%) in group B (P=0.44). After a median follow-up period of 15.7 (range 2-28) months for group A and 16.3 (range 3-31) months for group B, 19 patients in group A died and 21 patients in group B.

CONCLUSIONSFor esophageal cancer under T3N1M0, surgical outcomes are similar between prone thoracoscopic esophageal mobilization and left lateral position. Prone position may be associated with better lymph node dissection.

OBJECTIVETo inquire into the therapeutic effectiveness of free iliac crest grafts with periosteum on old acetabular defects.

METHODSFrom February 1996 to June 2005, 9 patients were treated with free iliac crest grafts with periosteum to reconstruct old acetabular defects. There were 7 males and 2 females and the average age was 41.3 years. The acetabular defects were caused by traffic accidents in 6 cases and fall injury in 3 cases. The time from injury to treatment was 4-13 months and averaged 8 months. Intraoperatively we firstly removed the acetabular fracture fragments of the posterior wall. The femoral head was then reduced. Bone graft was harvested from the iliac crest with periosteum, which was sculpted with a rongeur to conform to the defect. The concave (iliac fossa) side of the graft was placed toward the femoral head. The graft was securely fixed by two to three leg screws.

RESULTSPostoperative syndrome was not found in any of the cases. Harris' score system showed that the score raised from 32.3 points preoperatively to 81 points postoperatively. The hip function was evaluated as excellent in 3 cases, good in 4 cases and fair in 2 cases.

CONCLUSIONSAlthough this procedure could not exactly reproduce the anatomy of the hip joint, it enables to restore the posterior stability, provide bone-stock for the hip joints and prevent dislocation of the femoral head.

OBJECTIVETo investigate the changes of serum levels of chitinase-3-like-1 protein (YKL-40) and high-sensitivity C-reactive protein (hs-CRP) in patients with non-ST segment elevation acute coronary syndrome (ACS), to explore its correlation with its severity, and to observe the effects of Guizhi Fuling Decoction (GFD) on levels of blood lipids, YKL-40, and hs-CRP.

METHODSRecruited were 72 patients with unstable angina (UA) or non-ST segment elevation myocardial infarction (NSTEMI) at Department of Integrative Medicine, First Affiliated Hospital of Xinxiang Medical College from August 2010 to June 2011. They were randomly assigned to the treatment group (36 cases) and the control group (36 cases). All patients were treated by routine treatment, but patients in the treatment group took GFD additionally. The course of treatment was four weeks. According to the severity degree, all patients were graded to four ranks: low-risk group of UA, medium-risk group of UA, high-risk group of UA, and NSTEMI. The levels of YKL-40 and hs-CRP, and the correlation of severity degree were analyzed. Before and after treatment levels of triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) were measured. Before treatment, at two weeks, and after treatment the serum levels of YKL-40 and hs-CRP were detected. The relationship of YKL-40, hs-CRP and the severity of the disease were analyzed.

RESULTSLevels of YKL-40 and hs-CRP were positively correlated with the severity of the disease respectively (r = 0.729, P < 0.05; r = 0.655, P < 0.05). The positive correlation also existed between YKL-40 and hs-CRP (r = 0.848, P < 0.05). There was no statistical difference in the levels of blood lipids, YKL-40, or hs-CRP between the two groups before treatment (P > 0.05). Compared with before treatment, the levels of YKL-40 and hs-CRP significantly decreased in both groups after two weeks of treatment (P < 0.05). The levels of TG, TC, LDL-C, YKL-40, and hs-CRP significantly decreased, while the HDL-C level increased in both groups after treatment (P < 0.05). The level of HDL-C in the treatment group was higher, while levels of YKL-40 and hs-CRP were lower after treatment, when compared with the control group (all P < 0.05).

CONCLUSIONOn the basis of anti-inflammation and adjusting blood lipids by Western medicine, GFD could further reduce the serum levels of YKL-40 and hs-CRP of ACS patients, elevate the HDL-C level, and play anti-atherosclerosis effects.
