Gallstone disease is highly prevalent in clinic,particularly in women and some specific ethnic groups.The formation of water-insoluble cholesterol crystals is due to a misbalance between the three major lipids present in the bile:cholesterol,bile salts,and phospholipids.Many proteins implicated in biliary lipid secretion in the liver are regulated by several transcription factors,including nuclear receptors LXR and FXR.Human and murine genetic,pathophysiological evidence is consistent with the relevance of these nuclear receptors in gallstone formation.In addition,there is emerging data that also suggests a role for estrogen receptor ESR1 in abnormal cholesterol metabolism leading to gallstone disease.A better comprehension of the role of nuclear receptor function in gallstone formation may help doctors to design new and more effective therapeutic strategies for this highly prevalent disease condition.

[Objective]To evaluate the efficacy and safety of Tanreqing injection in the treatment of viral pneumonia.[Methods]CNKI database, VIP database and CBM database were searched by keywords, and the obtained references were screened for clinical trials on the introduction of Tanreqing in therapy of viral pneumonia. The clinical trial results of efficacy were meta-analyzed. [Results]7 clinical trials were included, involving 604 patients, the result of Chi-Square testing was 2.21(P=0.09, I2=0%), so a fixed effect model was chosen and the results showed that Tanreqing injection showed a better clinical thera-py than control group[odd ratio (OR):5.45, 95% confidence interval (CI): (2.89, 10.27), Z=5.25, P<0.00001]. No serious adverse effects were reported. [Conclusion]Tanreqing was more effective and safer in the treatment of viral pneumonia according to our results. However, higher quality clinical studies are needed as most trials included in this review are of lower quality.

Categorical perception (CP) is the unique phenomenon that gradually morphed physical feature in a stimulus continuum tends to be perceived as discrete representations. CP has been evidenced in several modalities in the sensor perception. The first study of CP of phonetic perception was performed in 1957. However, the early CP studies focused on segmental features. The first study of CP of pitch contours was performed until 1976. This article will review the results of previous studies focus on the categorical perception applies to the lexical tone perception.

Introduction: Choledocholithiasis is present in approximately 15-20% of patients with gallstone and laparoscopic common bile duct exploration has been effectively employed many cases currently. National Center for Health Development, Mongolian Ministry of Health, registered 23180 cases of bile duct diseases which were 3.4% of total diseases, 2.5% of total surgery, 12.2% of total gastrointestinal disease, 46.9% of total liver and biliary tract diseases between 2000 and 2006. Biliary tract diseases increased 2.4 times and bile duct surgery increased 5.2 times than 15 years ago in Mongolia. To compare open choledocholithotomy and laparoscopic choledocholithotomy for common bile duct stones. Materials and Methods: This study was carried out in Mongolian national second central hospital and Inner Mongolian first medical university hospital. The clinical data of the106 patients with common bile duct stones were analyzed between Арril 2015 and Арril 2016. Duration of operation, blood loss, postoperative complication, period of hospital stay and expenditure of treatment were compared in open choledocholithotomy and laparoscopic choledocholithotomy. All patients were placed on a “T” tube drainage. Results: In results of the duration of operation (p=0.001), blood loss (p=0.001) and period of hospital (p=0.01) were significantly lower in laparoscopic choledocholithotomy group Postoperative complications and gastrointestinal function recovery time were lower in laparoscopic group whereas expenditure of treatment were lower in open choledocholithotomy. Conclusion: In conclusion main advantages of laparoscopic choledocholithotomy were reduced duration of operation, blood loss, period of hospital stay and lower postoperative complications however costly.

Objective To observe the effect of rapid reduction of physical activity on bone mass (BMC), bone mineral density (BMD)and bone metabolism in growing rats. Methods 48 male SD rats were divided into the high-intensity exercise group (T1, n=12), high tolow-intensity exercise group (T2, n=12), low-intensity exercise group (T3, n=12) and control group (Con, n=12). During the first 6 weeks,the rats in T1 and T2 group ran on treadmill with high intensity, while rats in T3 group took low-intensity treadmill exercise. 6 rats were sacrificedfrom each group at the end of 6th week. BMC, BMD of femur were measured with DEXA. Alkaline phosphatase (ALP), osteocalcin(BGP), tartrate-resistant acid phosphatase (TRACP) were detected with ELISA. The exercise intensity of T2 group was reduced rapidly to alow level as in T3 group, but remained in the other 2 groups. At the end of the second 6 weeks, the other rats were investigated again. ResultsCompared with the first measurements, ALP and BGP of the T2 group decreased significantly (P<0.05), and TRACP increased (P<0.05). There was no significant difference in BMC and BMD of femur (P>0.05). Conclusion Rapid reduction of physical activity can suppressbone formation and stimulate bone resorption of long bone among growing rats.

Objective To observe the effects of pulsed electromagnetic field (PEMFs) or/and exercise on the area bone mineral density (aBMD) and volume bone mineral density (vBMD) of rats with osteoporosis induced by tretinoin gastric perfusion.Methods 100 female SD rats were randomly divided into 5 groups with 20 rats in each group： PEMFs group, exercise group, PEMFs plus exercise group, osteoporosis group and healthy control group. Except for the healthy control group, the osteoporosis models of other 4 groups were built by tretinoin gastric perfusion. After the building of models, each group was intervened with different treatment. In the 4th, 6th and 8th week after treatment, relevant Results of aBMD and vBMD were tested.Results Compared with the osteoporosis group, the BMD of the rats of PEMFs group, exercise group, PEMFs plus exercise group significantly increased significantly ( P＜0.05) in the 6th week, 4th week and 4th week after treatment respectively. In the 6th and 8th week, there was no significant differences among the PEMFs plus exercise group, the exercise group and the PEMFs group ( P>0.05).Conclusion PEMFs can increase the BMD of the rats with osteoporosis as well as exercise. PEMFs takes effect slower than exercise.

Objective To explore the protective effect of monosialoganglioside (GM1) on rats with acute brain trauma and its relevant mechanism.Methods Localized brain contusion model in rats were constructed by Feeney's method.65 SD rats were randomly divided into three groups: sham-operation group (n=5), brain injury group (n=30) and GM1 group (n=30).The rats were killed at 3, 7, 14, 28, 56, 168 h after administration, 5 rats in each group (1 rats in sham-operation group).Bax and Bcl-2 protein expression and PARP were decected by immunohistochemical method.The neuronal apotosis was detected by TUNEL.Results There were significant differences in expression of Bax and Bcl-2 protein between brain injury group and sham-operation group at each time point (P<0.05).There were significant differences in expression of Bax and Bcl-2 protein between GM1 group and brain injury group at each time point ( P <0.05 ) , while there were no significant differences in expression of Bax and Bcl-2 protein after 14 h between GM1 group and sham-operation group.After administration, the Bax/Bcl-2 values decreased and was obvious at 14 h.Degradation of PARP and rate of neuronal apotosis in brain injury group at each time point were significantly higher than those in sham-operation group (P<0.05).Degradation of PARP in GM1 group at 28 h, 56 h, 168 h were significant lower than those in brain injury group (P<0.05), and rate of neuronal apotosis was lower at each time point than those in brain injury group (P<0.05).Conclusion GM1 could reduce value of Bax/Bcl-2, degradation of PARP and apoptosis in rats with traumatic injury brain.

BACKGROUND:Intertrochanteric fracture is one of the common complications in patients with senile osteoporosis.Internal fixation is a common method in clinical therapy.Different internal fixators are selected in different studies.However,there are few studies on influential factors for outcomes of internal fixation at present.OBJECTIVE:To investigate related influential factors for outcomes of internal fixation in elderly patients with osteoporotic intertrochanteric fracture.METHODS:A total of 86 elderly patients with osteoporotic intertrochanteric fracture,who were treated in the Guanghua Hospital from May 2011 to May 2014,were enroled in this study.They were divided into three groups according to different manners of fixation.There were dynamic hip screw group (n=34),proximal intramedulary nail group (n=41) and proximal femoral compression plate group (n=11).Rate of fixation failure was compared among the three groups.The relevant factors affecting fixation effects were analyzed using univariate and multivariate analysis.RESULTS AND CONCLUSION:Internal fixation failure was detected in 5 patients (15％) in the dynamic hip screw group,11 patients (26％) in the proximal intramedulary nail group,and 4 patients (36％) in the proximal femoral compression plate group.Results of univariate analysis revealed that Evanse genotyping of patients,whether fractures were found on outer arm side,degree of osteoporosis,quality of reduction,steeple distance,whether combined with internal medicine diseases and selection of fixator were associated with internal fixation effects (P＜ 0.05).However,the internal fixation effects were not correlated with gender,age,hospital stay and ambulation time (P＞ 0.05).Multivariate analysis results demonstrated that unstable fractures,severe osteoporosis,fractures of the lateral arm,medical ilness,steeple distance ＞ 25 mm,and different internal fixators are independent factors affecting internal fixation effects in patients.
