In 2002, 99.807 blood slides were taken and examined in Thanh Hoa province, of which 33.464 slides were taken from fever patients (33.52%). 196 positive cases were detected. 52 microscopic points were checked, of which 10 microscopic points were very good functioning (19.23%), 27 points were good (59.9%), 12 were average and 3 were not good (5.76%). The quality of slides taken by the commune and village health workers was not so good, the slides were too thick or too thin with blood. In some villages, the slides were taken massively in order to fulfill the target. Checking the quality of microscopy showed that the mistake rate of microscopy was 13.16% as compared with the total slides sent for rechecking. In some microscopic points, the mistake rate was high (the provincial hospital had the mistake of 6/19 positive slides)

From March 1997 – September 2002, study on 31 patients intracerebral hemorrhage (28 male, 3 female) and 16 patients of control group (14 male, 2 female). The mortality of surgical treatment group was 32% and control group was 56%. Most of the benefit was in patients with lobar hemorrhage and following criteria: volume of hematoma  60cc, age  70, GCS  8. These is some suggestion that in the next future the treatment of intracerebral hemorrhage will involve non-invasive, stereotactic aspiration of hemorrhage through a single burr hole within hours

Over the last decade there is strong evidence indicating that hyperhomocysteinemia appears to be an important risk factor for vascular diseases, including cerebrovascular disease and myocardial infarction. Several multicenter-randomized trials have demonstrated that it is independent to other well known risk factors such as hypertension, diabetes mellitus, hyperlipidemia and smoking. Given the intense interest of our community concerning the prevention of cerebrovascular diseases we begin to measure homocysteinemia with a simple and accurate technique. The first results of our study raise the exciting possibility that homocysteinemia levels can be normalized by an inexpensive, well tolerated therapy with folate, pyridoxine hydrochloride and cyanocobalamin.

AIM:To compare the effect of three types of pterygium surgery and on tear film in patients with type 2 diabetes mellitus. ·METHODS:A total of 102 patients ( 102 eyes ) with pterygium combined with type 2 diabetes mellitus treated in our hospital from March 2013 to March 2016 were analyzed retrospectively. The patients were divided into three groups including the 34 cases ( 34 eyes ) with simple excision of pterygium ( resection group ) , pterygium excision combined with conjunctival flap transplantation in 34 cases (34 eyes, as conjunctival flap group ) and pterygium excision combined with limbal stem cell transplantation in 34 cases ( 34 eyes, as stem cell group ) . The wound repair time, complications, recurrence rate, uncorrected visual acuity (UCVA), tear film break-up time ( BUT ) and basal tear secretion test (SⅠt) were observed before, and 6 and 12mo after surgery in the three groups, respectively. ·RESULTS:The postoperative UCVA of the three groups was significantly higher than that preoperation ( P =0. 039, 0. 013, 0. 024 ), and there was no significant difference among the three groups ( P = 0. 317 ). The wound repair time was 5. 67 ± 1. 45d in the resection group, which was significantly higher than that in the conjunctival flap group (4. 18 ± 0. 76d) and the stem cell group (4. 09±0. 79 d) (P<0. 001), there was no significant difference between the conjunctival flap group and the stem cell group ( P = 0. 937 ). There were 4 cases in resection group reappeared, and the recurrence rate was 11. 8%, which was significantly higher than the other two groups ( P = 0. 037 ). There were 1 recurrences in the conjunctival flap group, and the recurrence rate was 2. 9%, while the patients in the stem cell group had no obvious recurrence. SⅠt and BUT increased significantly after operation (P<0. 05), especially in conjunctival flap group and stem cell group (P<0. 001). There was no significant difference between the conjunctival flap group and the stem cell group (P=0. 845, 0. 894). · CONCLUSION: Pterygium excision combined with conjunctival flap transplantation or limbal stem cell transplantation for the treatment of type 2 diabetic patients with normal blood glucose and tear film function has the similar effect, and is better than simple pterygium excision.

Objective: To investigate the therapeutic effect of combination of acupuncture and medicine in treating allergic rhinitis. Methods: Acupuncture, moxibustion, nasal inhalation and oral administration of Chinese materia medica were used as a composite treatment for different constitutions. The relations of the patient's age, syndrome type and course of disease to the therapeutic effect were investigated. Results: Among the treated 92 cases, marked effectiveness occurred in 68, effectiveness in 16 and ineffectiveness in 8, with a total effective rate of 91.3%. The therapeutic effect was not good in the patients who belonged to dry heat in lung meridian type and had the course of disease for more than 20 years. Conclusion: A combination of acupuncture and medicine has an exact therapeutic effect on allergic rhinitis.

Objective The aim of this study was to investigate the distribution of body weight related index and to explore the relationship between weight related index and cardiovascular diseases in rural residents in Yunnan Province. Methods By random cluster sampling method,rural residents were selected in Yunnan Province. The data were collected by face-to-face questionnaire and medical examination. Results 4070 rural residents in Yunnan participated in this study. The survey results showed that gender,age,education level and ethnicity affected both the distribution of body weight related index and low body weight,overweight,obesity,and central obesity(P < 0.05). Compared with low body weight,non overweight,non obesity and non central obesity group,non low body weight,overweight,obesity and central obesity group had higher prevalence rate of hypertension(P < 0.01). Among central obesity group,the prevalence rate of coronary heart disease was higher than non central obesity group(P < 0.01). Conclusion The distribution of body weight related index in rural residents of Yunnan province showed some special characteristic. The overweight,obesity,and central obesity were related to cardiovascular diseases. Change unhealthy living habits or behavior as well as improving their cultural quality have effects on controlling body weight related index and help to reduce the prevalence rates of overweight,obesity and central obesity which can further reduce the prevalence rates of cardiovascular diseases.

PROPELLER (periodically rotated overlapping parallel lines with enhanced reconstruction) is a new method of MRI data collection and reconstruction technique for reducing motion artifact. However, the minimum imaging time in PROPELLER is markedly longer than in conventional fast MRI. Through the current research of K-Space Undersampling algorithm based on PROPELLER technique, a proper undersampling method is conducted and then proved by simulation. The new data collection method can shorten the PROPELLER time without causing more image artifacts, which improves the value of PROPELLER technique.

OBJECTIVETo evaluate the role of serum level of procalcitonin (PCT), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and white blood cell count (WBC) as predictors in postoperative early infectious complications with fever after posterior lumbar internal fixation (PLIF).

METHODSA retrospective study was conducted from January 2012 to January 2014. Fifty-two patients with fever in the early stage(within 10 days) after the PLIF were collected in the study. They were divided into infection group and non-infection group (group A and group B) according to the results of postoperative blood culture. There were 26 patients in group A and 32 patients in group B. The values of PCT, CRP, ESR, and WBC count were compared and analyzed between two groups.

RESULTSThe values of PCT, CRP, and ESR in group A were higher than those of group B. Meanwhile, CRP and ESR in group B were still higher than the normal range. Among the 26 patients with infections (group A), PCT was superior to CRP and ESR, had a good ability in discriminating different kinds of postoperative infections. The area under the ROC curve of serum PCT levels was the largest (CI 95% was 0.81 to 0.98) in the indexs; and ROC curve of WBC count was no statistically significant. When the cut off points of each predictors were evaluated, the higher sensitive was CRP and reached at 90.27% and the higher specific was ESR and reached at 88.50%.

CONCLUSIONFor the patients with fever at the early stage after the PLIF should be paid attention and reasonable choosing predictors are helpful to identify postoperative infection in the early stage. The CRP and ESR may be influenced by the surgery, and the PCT level is helpful to differentiate infection type.

BACKGROUND:Human umbilical vein endothelial cells transfected with lentivirus containing enhanced green fluorescent protein can be easily traced. The optimal multiplicity of infection and time for producing strong fluorescence intensity can lay the foundation of tracing human umbilical vein endothelial cells in animal models.
OBJECTIVE:To observe expression of lentivirus containing enhanced green fluorescent protein in human umbilical vein endothelial cells, and thereby to find a stable method to label human umbilical vein endothelial cells.
METHODS:Using 0.1%col agenase perfusion digestion, we isolated human umbilical vein endothelial cells, which then were placed into a culture medium containing 20%fetal bovine serum and endothelial cellgrowth factor and observed under an inverted microscope. Fol owing digestion, centrifugation and suspension, the cells were counted and divided into four groups, 5.0×105 cells in each group. After cells were seededonto 24-wel plates, 10μL serum-free Dulbecco’s modified Eagle’s medium was added into the blank group, and lentiviruses containing enhanced green fluorescent protein were added into another three groups for celltransfection respectively at multiplicities of infection of 2, 3, 4. There were three dishes in each group.
RESULTS AND CONCLUSION:After cultured for 5-7 days, isolated cells grew into a single layer and exhibited a cobblestone-like arrangement under a light microscope. In addition, factor VIII related antigen test was positive. A green fluorescence was visible at 24 hours of transfection, and peaked at 72 hours. Transfection efficiency was in a linear growth with the multiplicity of infection. Up to the 21st day of transfection, the green fluorescence was stil visible. After 0, 7, 14, 21 days of transfection, the number of human umbilical vein endothelial cells showed no difference between the transfection group with the multiplicity of infection=3 and blank group, suggesting the proliferative ability of cells has no changes after transfection with lentivirus containing enhanced green fluorescent protein. These findings indicate that the lentivirus containing enhanced green fluorescent protein can highly transfect human umbilical vein endothelial cells, and green fluorescent protein can sustainably express for 21 days but cannot impact the cellproliferation.
