Objective To explore the influence factors of TCM syndrome characteristics distribution of alcoholic hepatic fibrosis. Methods The study overall collected and discussed the influence factors of TCM syndrome characteristics distribution of alcoholic hepatic fibrosis patients by adopting the principles and methods of clinical epidemiology based on the previous research of TCM syndrome characteristics. Results The important influence factors of TCM syndrome characteristics distribution of alcoholic hepatic fibrosis were total alcohol intakes and the total alcohol intakes under family alcoholism history condition. Conclusion The degree of viscera damage by alcohol is closely related to the distribution of TCM syndrome characteristics of alcoholic hepatic fibrosis and its pathogenesis evolution. The genetic constitution is one of the important influence factors of TCM syndrome characteristics distribution of alcoholic hepatic fibrosis.

Objective To probe into the inhibiting action of Compound Biejiarangan Troche on alcohol hepatic fibrosis in rats. Methods Forty Wistar male rats were divided into control, model, Compound Biejiarangan Troche and Anfate treatment groups. Alcohol hepatic fibrosis model was established by intragastrical perfusion with mixture of "alcohol-Pyrazole-coil oil" and high-fat diet for sixteen weeks. After four weeks’ intervention, changes of hepatic fibrosis index, liver tissue pathology and expression of TGF-?1 in liver tissue were observed. Results The hepatic function of model rats were changed and abnormal, with obvious fibrosis in hepatic histopathology. After intervention for four weeks, HA decreased (P

This study demonstrates that nerve growth factor (NGF) plays a protective role in myocardial infarction and early reperfusion by reducing the myocardial cell apoptosis and by improving ventricular remodeling and seeks to assess the effects and mechanisms of NGF on late reperfusion after myocardial infarction. The models of late reperfusion were established by ligating the left main coronary artery and then cutting the suture 2 hours after coronary artery ligation. The rats in NGF treatment group were injected 10 µL Ad-NGF (by constructing the adenovirus vector Ad-NGF containing NGF gene) at four locations around infarction. The rats in adenoviral vector (Adv) group were injected 10 µL adenoviral cector as the NGF group. The late reperfusion group and the sham group were given normal saline as above, and the sham group underwent thracotomy without coronary ligation. On the 3rd, 7th, 14th and 28th day after operation, we investigated the role of NGF on late reperfusion by recording cardiac structure and function with echocardiography, by examining the expression of NGF and VIII factor with immunohistochemical method, and by evaluating the myocardial cell apoptosis with terminal dUTP nick end-labeling method (TUNEL). We found that the NGF group had higher expression of NGF protein (P < 0.01) and lower apoptosis index (AI) (P < 0.01 or P < 0.05) compared to the late reperfusion group and Adv group on all time points. The NGF group had remarkably higher level of neovascularization compared to the late reperfusion group on the 14th day (P < 0.01) and the 28th day (P < 0.05). The NGF group also had higher LVEF and FS levels compared to the late reperfusion group on the 14th day (P = 0.006, P = 0.006) and on the 28th day (P = 0.000, P = 0.000). Whereas the NGF group had lower LVEDD, LVESD (P = 0.038, P = 0.000) and lower LVEDV, LVESV (P = 0.001, P = 0.000) on the 28th day compared to late reperfusion group. In this experiment, the NGF gene carried by adenovirus vector had been transfected and obviously increased the expression of NGF protein in NGF group. NGF may help postpone the myocardial remodeling and improve the heart function by promoting the myocardial neovascularization and inhibiting myocardial apoptosis.

BACKGROUND:Tranexamic acid has been more and more used in reducing bleeding after joint replacement, but its usage method and dosage remain controversial, and become a hot focus in recent years. OBJECTIVE:To investigate the efficacy of intra-articular injection of tranexamic acid on postoperative blood loss and limb circumference changes in patients who received unilateral total knee arthroplasty. METHODS:From March to October 2013, clinical data of 90 patients undergoing primary unilateral total knee arthroplasty were randomized to the tranexamic acid group and the control group, including 19 males and 71 females. The 30 patients in the tranexamic acid group received 50 mL of 3%tranexamic acid dilute solution inside knee joint after capsule closure, and 60 patients in the control group received the same volume of physiological saline. No significant difference in age, height, body mass index, anticoagulation, the type of prosthesis, tourniquet time and preoperative diagnosis was detected between the two groups (P>0.05). The amounts of intraoperative and postoperative blood loss and blood transfusion, postoperative drainage volume, the preoperative and postoperative limb circumference 10 cm above the operated knee were recorded. Routine blood test was reviewed after the surgery. RESULTS AND CONCLUSION:There were no significant differences in total blood loss, postoperative drainage volume and limb circumference changes between tranexamic acid and control groups (P>0.05). The amount of postoperative hidden blood loss was significantly less in the tranexamic acid group than in the control group (t=-2.683, P<0.05). These data suggested that the intra-articular injection of tranexamic acid intraoperatively in patients receiving total knee arthroplasty could significantly reduce the amounts of postoperative hidden blood loss, and did not affect the postoperative limb circumference changes.

Objective To explore the clinical trait and relationship between clinicopathological characteristics and prognosis in Uygurs women with breast cancer of Xinjiang. Methods The clinicopathological data of 74 cases with breast cancer of Uygurs women were analyzed, multivariate analysis was done by COX proportional hazard model. Results 74 cases have followed up: there-year and five-year survival rates were 75.00 %(48/64) and 43.50 %(20/46)respectively. Multivariable COX regression revealed that patient age, menstruation, status of involved lymph node, TNM and the expression of PR were five important and independent prognostic factors for breast cancer of Uygurs women, the hazard rations of these factors were 0.037, 0.103, 13.851, 18.877, and 0.046, respectively. Conclusions The proportion of breast cancer of Uygurs women was low in patient of Xinjiang, but patient age was young, age of onset were more than half between 36 and 50 years old and mainly belong to Ⅱ, Ⅲ stage of TNM, prognosis was poorly. Patient age, menstruation, status of involved lymph node, TNM and the expression of PR serve as independent prognostic indexes of breast cancer of Uygurs women. Early diagnosis and treatment are very important to improve the survival rate of breast cancer patients

Objective Postoperative cognitive dysfunction (POCD) is a common complication of cardiac surgery, which seriously affects the prognosis of the patient.This study aimed to explore the risk factors for early POCD in patients undergoing cardiac valve surgery and the correlation between early POCD and the serum S100B protein level.Methods Eighty patients underwent mitral valve replacement surgery in combination with tricuspid plasty.At 1 day before and 5 days after surgery, we assessed the cognitive function of the patients and divided them into a POCD and a non-POCD group.We obtained such data as the age, sex, education, New EuroSCORE Ⅱ, and preoperative NYHA cardiac function grades and left ventricle ejection fraction (LVEF) of the patients, collected the venous blood to determine serum S100B protein concentration by ELISA, and analyzed the independent risk factors of early POCD using single-factor and binary logistic regression analyses.Results POCD was found in 20 (25%) of the patients, , Logistic regression analysis showed the independent risk factors for early POCD to be hyperglycemia (OR=6.038, 95% CI: 1.202-30.337), operation time (OR=6.423, 95% CI: 1.276-32.332), and aspartate aminotransferase (AST, 2 times higher than normal) (OR=12.878, 95% CI: 2.289-72.445).The serum S100B protein concentrations in the POCD group were (1.9±0.3) μg/L and (1.7±0.4) μg/L at 48 and 72 hours after cardiopulmonary bypass, significantly lower than (2.4±0.4) μg/L and (2.1±0.3) μg/L at 30 minutes and 24 hours (P<0.05), and so was it in the non-POCD group at 72 than at 48 hours postoperatively ([1.4±0.4]) vs [1.5±0.4] μg/L, P<0.05).Conclusion Long operation time, perioperative hyperglycemia and high AST are independent predictors and the serum S100B protein level is a significant marker of early POCD.

BACKGROUND:As a more common method in the orthopedic field, the method of intra-articular injection drugs has distinct curative effects, but there are some complications. In a certain extent, this method caters to the psychological fear of surgery, and can serve as a kind of conservative treatment. But some experts believed that because of the limit of sterile conditions, intra-articular injection of drugs wil increase the risk of intra-articular infection and they opposed this method.
OBJECTIVE:To review the efficacy and adverse reactions of intra-articular injection drugs in recent years, and explain clinical applications of intra-articular injection drugs in orthopedics.
METHODS:A computer-based search was conducted in PubMed and Wanfang database for articles related to the application of intra-articular injection drugs in orthopedics published between January 2007 and December 2013. The English and Chinese key words were“intra-articular, injection, orthopaedics, tranexamic acid, hyaluronic acid, corticosteroid, drugs”. Data were checked in the first trial, old articles and repetitive studies were excluded. The relevant 43 articles accorded with inclusion criteria were reviewed.
RESULTS AND CONCLUSION:In orthopedics, the method of intra-articular injection drugs is simple, economic and effective, but at the same time, there are some side effects. Tranexamic acid by intra-articular injection can significantly reduce blood loss after total joint replacement, is safety and economic. Intra-articular injection joint lubricant can reduce internal friction of joints and improve the adhesion of joint cavity, can be used as a good conservative treatment for osteoarthritis. Intra-articular injection hormone drugs can treat inflammatory arthritis, and short-term curative effect is obvious, but due to large long-term side effects, the method is not recommended now. Intra-articular injection of analgesic drugs and other drugs have both advantages complications. The efficacy of intra-articular injection drugs in orthopedics is obvious;meanwhile, this method has some complications. Orthopedic surgeons should select related drugs by indications. We stil need to further make reasonable regimen with intra-articular injection drugs in future large-scale study.

Objectives To explore the effect of holder pasteurization, frozen storage time and thawing methods on macronutrients and energy content of donor human milk, and to provide theoretical basis for the rational use of breast milk. Methods Thirty-three samples of donor human milk were collected and an aliquot of each sample was analyzed before and after pasteurization. The remaining milk after pasteurization was split into 9 aliquot , and frozen at -20 ℃. After 30, 60, and 90 days, the milk was thawed by three different methods of room tempe-rature, 4 ℃ refrigeration, and 37 ℃ water bath, respectively. The nutrient components of each aliquot were analyzed and compared. Results We observed a mild reduction in fat and energy content after pasteurization (P <0.05). A significant decrease of fat, protein and energy content with the prolonged storage time was observed (P <0.01), and during the whole process (pasteurization + frozen storage), the decrease of fat, protein and energy content was 36.6%, 32.6%and 22.6%, respectively. The protein was influenced mostly by different thawing methods and the content of protein reached highest while thawed at 4 ℃ refrigeration. Conclusions Holder pasteurization and frozen storage at-20℃significantly reduce fat, protein and energy content of donor human milk. The donor milk should be used as quickly as possible when applied for preterm infants and thawing at 4 ℃ refrigeration is recommended before delivery to newborn infants.
