Calcium oxalate (CaOx) stone is the main type, and its formation is closely related to the metabolism of oxalic acid and calcium. Gut Microbiome is normal microflora which settled in the human intestinal tract and plays an important role in regulating a variety of metabolism in the body. In the past, Oxalobacter formigenes in gut was a protective factor for the formation of CaOx stones. Recently, it has been found that the bacteria regulating oxalate metabolism were not limited to Oxalobacter formigenes. Gut Microbiome of CaOx stones formers is different from healthy people. It regulates the metabolism of oxalic acid in the body through the gut-kidney axis and affect the formation of CaOx stone. The purpose of this study is to describe the characteristics of intestinal flora in patients with CaOx stones, and to summarize its potential function in the formation of CaOx stones and its possible clinical application in the future.

Objective:
To study the clinical features of dengue cases infected with hepatotropic virus and Mycobacterium tuberculosis in Xishuangbanna, and to provide evidences to set up effective treatment programs for the dengue patients infected with the other diseases for hospitals.
Methods:
The clinical characteristics of dengue cases infected hepatotropic virus and Mycobacterium tuberculosis were analyzed retrospectively on their symptoms and biochemical parameters from the People′s Hospital and the Infectious Disease Hospital of Xishuangbanna Prefecture in 2013 and 2015.
Results:
The clinical characteristics of dengue cases infected with hepatotropic virus were typical, and inclued low incidence of urinary abnormalities, coagulation disorders and high-lactate dehydrogenase. Dengue cases infected with Mycobacterium tuberculosis had high incidence of shock, high-hematocrit, renal function and coagulation abnormalities, which suggested a trend of more serious illness than other groups obviously.
Conclusions
The rate of severe disease was higher in dengue cases infected with Mycobacterium tuberculosis than those infected with hepatotropic virus, which suggests that the dengue cases infected with Mycobacterium tuberculosis should be treated timely to reduce the severity of the diseases in the hospital.

Objective:
To study the overexpression of protein phosphatase 2 regulatory subunit B''α gene effects on the proliferation and invasion of hepatoma cells.
Methods:
Immunohistochemistry method was used to analyze the expression of PPP2R3A in cancerous and paracancerous tissues. Hepatocellular carcinoma cell lines (Huh-7 and HepG2) with stably overexpressing PPP2R3A were constructed by lentiviral vector. Biological behavioral transition in hepatocellular carcinoma cell proliferation, cell cycle, apoptosis, invasion and metastasis were detected by cell counting kit-8 assay (CCK-8), flow cytometry, and transwell assay. A subcutaneous nude tumor mice model was constructed to validate the growth of hepatoma cells. Two independent sample t-tests were used to compare the groups.
Results:
The expression of PPP2R3A gene in human hepatocarcinoma tissues was higher than paracancerous tissues. The absorbance (A value) of hepatoma cells was increased (

ObjectiveTo investigate the clinical efficacy of vastus medialisoblique enhancement plus electroacupuncture intervention in treating patellar chondromalacia.MethodFifty-two patients meeting the inclusion criteria were randomly allocated to a treatment group of 32 cases and a control group of 20 cases. The treatmentgroup received vastus medialis oblique enhancement plus electroacupuncture intervention and the control group, electroacupuncture intervention alone. Both groups were treated once daily, 10 times as a course, for four consecutive courses. The Visual Analogue Scale (VAS) score was counted in the two groups before and after treatment. The clinical therapeutic effects were evaluated in the two groups.ResultThe VAS score improved significantly in both groups of patients after treatment compared with before(P<0.05). It improved significantly more in the treatment group than in the control group (P<0.05). The cure rate and the total efficacy rate were 37.5% and 96.9%, respectively, in the treatment group, which were higher than a cure rate of 20.0% and a total efficacy rate of 75.0% in the control group, respectively. ConclusionVastus medialis oblique enhancement plus electroacupuncture intervention can improve the clinical symptom of pain more markedly and heighten the clinical therapeutic effect in patients with patellar chondromalacia. Its effect is better than that of electroacupuncture intervention alone.

Objective To investigate the relationship between resting heart rate (RHR)and carotid artery structure in young hypertensive patients.Methods A total of 663 primary hypertensive patients aged between 18 and 45 (38.01 ± 5.78) were chosen from the First Affiliated Hospital of Xinjiang Medical University from January,2009 to January,2012.Patients under this study were divided into three groups according to their RHRs:group A (RHR<70 bpm,n=163),group B(70 bpm≤RHR<80 bpm,n=268),group C (RHR≥80 bpm,n=232).Data on bilateral carotid artery intima-media thickness,common carotid artery diameter were detected by carotid ultra-sonography.Indexes of carotid artery were analyzed by both variance and bi-variate correlation analysis.Results 1)Differences in the blood pressure among three groups showed statistical significance (P<0.01),with diastolic pressure in group A higher than in group B (P<0.05),while both systolic and diastolic pressure in group C higher than in group B (P<0.01).2)In group A,the right carotid artery diameter was higher than in group C(P<0.05) and the left carotid artery diameter higher than in group B(P< 0.05) with the left carotid artery diameter higher than in group C (P<0.05).3) Significant positive correlations were found between RHR and blood pressure (r =0.112,0.118) and negative correlation between RHR and left carotid artery diameter (r=-0.89).However,correlation between RHR and right carotid artery diameter was not significant (r=-0.075,P=0.068).Conclusion When blood pressure had an increase,we found that the carotid artery diameter was decreasing along with the increasing RHR among the young hypertensive patients.
