Objective To analyze the differences in urinary stone components between Uyghur and Han patients with urolithiasis in Xinjiang,and to explore the related factors contributing to the observed differences.Methods The data of urinary stone compo-nents in 317 adult patients with urolithiasis (152 cases of Uyghur nationality and 165 cases of Han nationality)admitted to Xinjiang Uygur Autonomous Region People′s Hospital from June 2009 to June 2011 were retrospectively analyzed.The urinary stone compo-nents were analyzed by the infrared spectroscopy.Results There were significant differences in thestone component proportions of calcium oxalate monohydrate (COD),COD+carbapatite (CA)and uric acid (UA)between Uyghur and Han patients(P <0.05). Conclusion The characteristics of the urinary stone comppnents have significant differences between Uyghur and Han patients with urolithiasis,which may be related with ethnicity and the different dietary habits.

Objective:To analyze the reasons for unplanned resection of soft tissue sarcomas and explore the treatment strategies for cancer surgery. Methods: The study included 105 patients with soft tissue sarcomas admitted to the First Affiliated Hospital of Xinjiang Medical University between October 2009 and December 2012. The average age of the patients was 52 years old. Among the patients, 65 were males and 40 were females. Up to 82 patients underwent planned resection (Group A) in our hospital, and 23 underwent unplanned resection (Group B) in other hospitals. Wide excision and radical resection were conducted in Group A, whereas extended resection was performed in Group B. General data, tumor location and size, resection margin, local recurrence and metastasis, and survival were statistically analyzed in the two groups. Results:The proportion attaining the margin of wide excision was obviously lower in Group A than in Group B (P＜0.05). The 3-year survival rate was significantly higher in Group B than in Group A (P=0.001). Within an average follow-up of 18 months (3 months to 36 months) in Group B, 12 patients died, including 9 with tumor metastasis and 3 with other diseases. Within an average follow-up of 23 months (5 months to 36 months) in Group A, 15 patients died, including 12 with tumor metastasis and 3 with other diseases. Conclusion:Compared with planned surgical operation, unplanned resection of soft tissue sarcomas often leads to inadequate resection margin, which results in a high incidence of local recurrence and an increased mortality. Thus, clinicians should attempt to avoid unplanned resection of sarcomas.

Objective:To analyze the clinical effect of different surgical methods on giant-cell tumor of bone (GCTB). Methods:Between January 2007 and June 2012, 37 patients receiving treatment for GCTB were enrolled in this study. These patients included 20 males and 17 females whose ages ranged from 20 to 56 (average=31.6). The prosthesis replacement and nonprosthetic replacement op-eration on the postoperative recurrence, limb function, comprehensive evaluation of the curative effect, as well as morbidity and recur-rence rate among different nations and in the upper and lower limbs of GCTB patients were analyzed. Results:The predilection age of the cases ranged from 20 to 50 years old. The incidence was higher in the Uighur population of Xinjiang, China. However, the recur-rence rate in ethnic difference was not statistically significant (P>0.05). Conclusion:The predilection age of GCTB cases was 20~50 years old, with higher morbidity in Uighur than in Han and other ethnic groups. The morbidity and recurrence rate were higher in the lower limbs than in the upper limbs of patients. The scraping bone graft and bone cement filling, the internal fixation of the scraping bone graft, and the artificial joint replacement of tumor resection were all reliable modes of treatment.

AIM: To investigate the changes and related factors of choroidal thickness(CT)in acute primary angle-closure glaucoma(APACG), and chronic primary angle-closure glaucoma(CPACG).

METHODS: It was a retrospective study. A total of 35 patients(43 eyes)with APACG, 26 patients(46 eyes)with CPACG and 46 patients(81 eyes)with normal eye condition and used as the control group in the study. EDI-OCT was used to measure and compare the foveal, nasal, temporal, superior and inferior CT of APACG, CPACG and normal control groups. The CT were labeled as subfoveal choroidal thickness(SFCT), nasal 2mm(N 2mm), temporal 2mm(T 2mm), superior 2mm(S 2mm), inferior 2mm(I 2mm).Linear regression analysis was used to explore the related factors of CT. Logistic regression analysis was used to evaluate the association between CT and presence of APACG and CPACG.

RESULTS: There was no significant difference in CT of APACG, CPACG and normal control group(P>0.05). CT of all sites was negatively correlated with axial length(AL). N 2 mm and I 2 mm were also negatively correlated with age, anterior chamber depth(ACD), SFCT was negatively correlated with age and AL(P<0.05). Multivariate Logistic analysis showed that there was an association between S 2mm and APACG(P=0.029), the odds ratio(OR)and 95% confidence interval(CI)was 0.975(0.953, 0.997). There was no association between CPACG and CT at all locations(P>0.05).

CONCLUSION: Age, AL and ACD are the factors that related to choroidal thickness. It is also confirm that there is an association between decreased S 2mm and APACG. However, there is no correlation between CPACG and CT at all locations.

Objective: To analyze the curative effect of 56 cases with surgical operation of congenital tumor in conus medullaris position, to provide valuable reference information for the surgical operation of congenital tumor in conus medullaris position. Methods: The cases were from 56 patients with congenital tumors in conus medullaris position in Xinjiang Uygur municipal people's hospital from January 2015 to February 2018. According to the classifications of congenital tumors in the conus medullaris position, surgical operation was performed on patients. The curative effect of patients with all kinds of congenital tumors in the conus medullaris position was analyzed and summarized. Results: After 9 months of the follow-up: ⑴ There were totally 18 cases of epidermoid cysts, 16 cases with obvious improvement in lower limb numbness and lower limb motor function, 13 cases with the pain degree effectively relieved and 3 cases without significant improvement in early defecation function. ⑵ There were 15 cases of teratomas, 13 cases without significant improvement in lower extremity numbness, 2 cases with reduced lower extremity numbness, 3 cases with reduced urination and defecation function disturbance and 1 case not recovered. There was no recurrence of tumor. ⑶ There were 8 lipoma patients who were cured and discharged without urination and defecation function disturbance. Life was basically self-sustaining. ⑷ There were 9 cases of hemangioblastoma with significant improvement in spinal cord function, 5 cases without postoperative pain symptoms and 1 case with significant improvement in pain degree. ⑸ There were 6 cases of ependymoma, 2 cases with significant reduction on limb numbness symptoms, 1 case with urinary retention after surgery. There was no significant change in muscle strength of the 2 cases before and after surgery. Conclusions The clinical effect of surgical operation of congenital tumor in conus medullaris position is clear. Combined with imaging examination and attention to surgical precautions, the surgical treatment effect of congenital tumors in the conus region of the spinal cord can be effectively improved.

Objective To analyze the clinicopathological features and prognostic factors of common subtypes of non-transparent renal cell carcinoma.Methods Retrospective analysis of 115 patients with pathologically confirmed non-transparent renal cell carcinoma from January 2003 to December 2017,including 67 males and 48 females,with a male to female ratio of 1.4∶ 1.The average age is (51.2 ± 13.4)years old.71 cases were asymptomatic renal cancer,44 cases had clinical symptoms,including 10 cases of gross hematuria,28 cases of low back pain,4 cases of hematuria with low back pain,and 2 cases of abdominal mass.There were 49 open surgery and 66 laparoscopic surgery.58 patients underwent radical nephrectomy and 57 underwent partial nephrectomy.Of the 115 patients,17 (14.9％) had abnormal hemoglobin (Hb),22 (19.1％) had abnormal platelet (PLT) count,18 (15.7％) had abnormal alkaline phosphatase,and abnormal lactate dehydrogenase 16 cases (13.9％).The Kaplan-Meier survival analysis method was used to calculate the survival rate of patients,and the Cox proportional regression risk model was used to analyze the prognostic factors.Results The postoperative pathological stage was 57 cases in T1a stage,38 cases in T1b stage,12 cases in T2a stage,8 cases in T2b stage,2 cases of regional lymph node positive,and 113 cases negative;no distant metastasis.Pathological types:42 cases of renal chromophobe cell carcinoma,37 cases of papillary renal cell carcinoma type Ⅰ,36 cases of type Ⅱ.The average follow-up time was 38.6 months,and the rate of loss of follow-up was 3.5％ (4/115).The 1,3,and 5 year overall survival rates of 115 patients with common subtypes of non-transparent renal cell carcinoma were 99.1％,95.8％,and 81.1％,respectively.Multivariate Cox regression analysis found that the pathological type (OR =4.625,P =0.014),four indicators ≥ 3 abnormalities (OR =30.853,P =0.024),lymph node metastasis (OR =35.663,P =0.006) were the group.An independent factor in the survival time of patients with common subtypes of non-transparent renal cell carcinoma.Conclusions Compared with papillary renal cell carcinoma type Ⅰ and renal chromophobe cell carcinoma,papillary renal cell carcinoma type Ⅱ has a higher degree of malignancy and a poor prognosis.The pathological types of the common subtypes of nontransparent renal cell carcinoma,four indicators (Hb,PLT count,alkaline phosphatase,and lactate dehydrogenase) ≥3 abnormalities and lymph node metastasis are independent prognostic factors for overall survival.

Obesity and diabetes mellitus (T2DM) are metabolic related diseases with high incidence rate at present. Obesity is considered as one of the risk factors of T2DM. At present, the interaction mechanism between obesity and T2DM has not been clearly studied.Adipose tissue is an endocrine organ related to the pathophysiology of obesity and its complications. Adipose tissue can not only store a lot of energy, but also secrete many hormones, oxidative stress and inflammatory factors, which may be related to the occurrence and development of T2DM. Under long-term and low-dose stimulation, the sustainable low grade inflammation of fat is considered to be an important mechanism for the occurrence and development of obese T2DM. Therefore, this paper mainly summarizes the research progress of low grade fat inflammation in obese T2DM.

Obesity is one of the main risk factors for gastroesophageal reflux disease (GERD). With the development of social economy, the global obesity population shows a continuous growth trend, leading to an increase in the incidence rate of GERD. Obesity, especially the central obesity, is closely related to GERD. The increase of intra-abdominal pressure caused by obesity may lead to the destruction of "anti-reflux barrier" through a variety of mechanical mechanisms, and the various cytokines produced by visceral adipose tissue in obesity population may contribute to the occurr-ence and development of GERD through various biological effects. The authors explore the mechanism of obesity in the occurrence and development of GERD from both mechanical and biological effects, aiming to help clinical physicians improve their understanding of GERD.
