1.Mechanisms of nuclear receptors in gallstone formation
International Journal of Surgery 2016;43(7):499-502
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.
2.A comparative study between laparoscopic versus open choledocholithotomy
Journal of Surgery 2016;19(1):23-28
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.

OBJECTIVETo explore the distribution features of Chinese medical constitutions in different ages population, thus providing scientific evidence of constitution process theory.
METHODSRecruited were 21 948 cases from a survey of Chinese medical constitutions and health conditions in 9 provinces or municipalities across China (including Jiangsu, Anhui, Gansu, Qinghai, Fujian, Beijing, Jilin, Jiangxi, and Henan) from Dec 2005 to Jan 2007. The body constitution type of individual was diagnosed using discriminant analysis on the basis of Chinese medical constitution questionnaire. By using correspondence analysis, the correlation between the general population, genders, ages, and Chinese medical constitution types was studied.
RESULTSConstitutions of yin-deficiency type, wetness-heat type, qi-depression type, and special diathesis type often occurred in the population ranging 15 -24 years old. Gentleness type mostly occurred in the population ranging 25 -44 years old. During this time period, phlegm-wetness type and wetness-heat type were liable to occur in males, while blood-stasis type was liable to occur in females. Qi-deficiency type and yang-deficiency type were most often seen in those older than 45 years. Phlegm-wetness type and blood-stasis type body constitution were also liable to occur in those older than 45 years.
CONCLUSIONSThe distribution features were different in different Chinese medical constitutions. Different constitution types exist in different genders. Different constitution types exist different ages population.

SUMOylation is a post - translational modification consisting of covalent conjugation of ubiquitin - like proteins called small ubiquitin related modifier ( SUMO ) . SUMO modification has been shown to significantly alter protein activity, which can modulate protein stability, affect protein-protein interactions, and modify protein localization and trafficking. This process adds another layer of control in eukaryote gene expression, and it regulates both transcriptional activation and repression. This article reviews the current situation and future development of SUMOylation in ophthalmology.

OBJECTIVE:
To investigate the epidemiological features in patients with allergic rhinitis (AR) in Yichang city, and put forward effective prevention and control measures.
METHOD:
Collecting the data of allergic rhinitis in city proper from 2010 to 2013, input the data into the database and used statistical analysis.
RESULT:
In recent years, the AR patients in this area increased year by year. The spring and the winter were the peak season of onset. The patients was constituted by young men. There was statistically significant difference between the age, the area,and the gender (P < 0.01). The history of allergy and the diseases related to the gender composition had statistical significance difference (P < 0.05). The allergens and the positive degree in gender, age structure had statistically significant difference (P < 0.01).
CONCLUSION
Need to conduct the healthy propaganda and education, optimizing the environment, change the bad habits, timely medical treatment, standard treatment.

Hyperlipidemia is a major factor causing coronary heart disease and atherosclerosis. The high-density lipoprotein cholesterol (HDL-C) is a major indicator for measuring lipid levels. However, there is no an effective medicine that can obviously increase HDL-C at present. According to previous laboratory studies, atractylodes macrocephalae extracts could significantly increase HDL-C level. In this study, the metabolic hyperlipidemia rat model was established by feeding high-sugar and fat diets and alcohol-drinking to explore the effect and mechanism of atractylodes macrocephalae extracts on hyperlipidemia rats. According to the findingins, different doses of atractylodes macrocephalae extracts could reduce the levels of TC, TG, LDL-C, ACAT and increase the contents of LCAT, HDL-C. Particularly, the atractylodes macrocephalae extracts (100 mg · kg(-1) group showed increase in HDL-C by about 50% and significant declines in HMG-CoA reductase, TC, TG. In conclusion, Atractylodes Macrocephelae Rhizoma extracts could effectively regulate the dyslipidemia of hyperlipidemia rats, especially on HDL-C. Its mechanism may be related to reduction in cholesterol synthesis by inhibiting HMG-CoA reductase in livers and increase in lipid metabolism and transport by regulating LCAT and ACAT levels.

Objective To establish CFPAC-1 cell lines deficient in CDC25B2 by recombinant lentivirus, and to investigate the role of this gene. Methods After CFPAC-1 cells were transduced with recombinant lentivirus producing CDC25B2 siRNA, stably transduced cells with green fluorescent protein were selected by flow cytometer. The mRNA and protein expression of CDC25B2 was examined by RT-PCR and Western blot analysis. The effect of the lentivirus on the cell proliferation, cell cycle, clone-forming, migration and invasion ability was analyzed by MTr method, flow cytometer, plate clone-forming assay and Transwell chamber method respectively. Results CDC25B2 siRNA knocked down CDC25B2 expression in CFPAC-1 cells significantly. The silencing efficiency of siRNA transduction by recombinant lentivirns was very high. Proliferation, cloneforming, migration and invasion ability of human pancreatic cancer cell line CFPAC-I were significantly in-creased, while cell cycle was not affected. Conclusion CDC25 B2 plays an important role in cell proliferation, clone-forming, migration and invasion of pancreatic cancer. This research provides experimental evidences for targeting CDC25B2 in gene therapy against pancreatic cancer.
