目的：探讨腹腔镜检查对胃癌分期的价值。方法: 2007 年1月至2007 年11 月收治的胃癌患者14 例胃癌患者在全麻下行腹腔镜检查。结果: 腹腔镜T分期与术后病理检查结果符合率为92.9％，术前临床T分期与术后病理检查结果符合率为64.3%。腹腔镜分期显著优于临床分期Plt;0.05。在14例术前临床分期均未发现腹膜转移的病例中，腹腔镜探查发现有腹膜转移（P1-P3）者4例，腹腔镜对腹膜转移的评估显著优于临床分期P lt;0.05。结论: 腹腔镜可作为常规检查手段的一种补充，能对进展期胃癌进行准确的诊断和分期，有助于手术决策制定及估计治疗结果与预后，避免不必要的剖腹探查。
OBJECTIVE: To investigate the location of transverse rectus abdominis musculocutaneous (TRAM) flap perforators on abdomen skin and the peak systolic flow velocities of the perforators. METHODS: A series of 94 consecutive patient’s TRAM flap perforators were detected by color-flow duplex Doppler scanning peroperatively. Perforator locations were tabulated on the abdomen skin according to their vertical position relative to the umbilicus and their lateral location relative to the abdominal midline. RESULTS: The perforators on both left and right side of TRAM flap were quite not symmetry. The peri-umbilical region contained 81.1% of the perforators. All perforators were detected with peak systolic flow velocities ranging from 5 to 81 cm/s. CONCLUSION: The preoperative color-flow Doppler localization of TRAM flap perforators improves the surgeon’s ability to design the flap in order to capture the dominant vessels, and select single- or double-pedicle and free TRAM flaps based on each patient’s individual characteristics.

Methods : At first screen cervical cytology of Uigur and Han outpatient and inpatient of department of gynecology and obstetrics in the People’s Hospital of Xinjiang Uigur Autonomous Region from January 1, 2000 to December 31, 2004Secondly biopsy for those patients that cervix pathological change shows positive, then contrast analysis and comprehensive evaluation. Results : Cervix smears are 23205 samples. Uigur nation has 6999 samples and Han nation has 16206 samples. There are 237 patients whose cervix pathological changes shows positive. Among them 173 samples were over CINⅠ(include CINⅠ,CINⅡ,CIN Ⅲ,carcinoma in situ, squamous carcinoma and adenocarcinoma) through colposcopy. The youngest was 31 and diagnosed carcinoma in situ(Uigur), the eldest was 76 and diagnosed squamous carcinoma(Han).The samples of Uigur is 105(6069%) and Han is 68(3931%).The positive samples in Uigur is higher than Han each year, the incidence has extremely significant difference among 2000,2001 and 2004(P lt;001), while it has significant difference between 2002 and 2003 (P lt;005), but in each age group it has no significant difference between Uigur and Han (P gt;005). Conclusion : The high incidence of cervical cancer and cervical precancerous lesion in xinjiang is contribute to environment, medical condition, medical development and aid measures coaffect.
Objective To determine the affected factors of intraorbital hemodynamic results in diabetic retinopathy (DR) and the risk factors related to the occurrence of DR. Methods Posterior ciliary artery (PCA), central retinal artery (CRA), central retinal vein (CRV), and vortex vein (VV) of 68 patients with DR were measured by color Doppler flow image (CDFI). Thirty-one hemodynamic parameters, including systolic velocity, diastolic velocity, mean velocity, resistive index, pulsatility index and accelerative velocity of ophthalmic artery (OA), and other variates (blood pressure, blood sugar, gender, age, duration of the disease, and so on) were collected and clustered in a principal components analys is following a forward, stepwise logistic regression on these components. Results Nine principal components were extracted from 37 original variates, reflecting the velocity of OA, velocity of PCA, resistance of OA, velocity of CRA,resistance of CRA, resistance of PCA, time-related factor, venous drainage factor and gender factor, respectively. In the result of logistic regression, resistance of OA, velocity of CRA, resistance of PCA, time-related factor, and venous drainage factor were the risk factors related to DR. Conclusion The first risk factor affecting DR is time, and intraorbital hemodynamic abnormity influencing the development of diabetic retinopathy may be the increase of resistance of OA, decrease of velocity of CRA, decrease of resistance of PCA, and increase of venous drainage.

Objective To evaluate the diagnosis of blue-on-yellow perimetry and macular threshold perimetry in early primary glaucoma. Methods Humphrey II 750 automatic perimetry was used to test 60 eyes of 60 cases in normal control group and 63 eyes of 63 cases in early primary glaucoma group with white-on-white perimetry (W/W), blue-on-yellow perimetry (B/Y)，and macular threshold perimetry (M TP). The results of the visual field defects detected by the three perimetries were compared and analyzed.Results The differences of mean sensibility of W/W, B/Y and MTP between the two groups had statistical significance［t=-3 .01, P=0.0054 (W/W); t=-2.95, P=0.006 3 (B/Y); t=-2.59,P=0. 0150 (MTP)］. In the diagnosis of early primary glaucoma, the sensitivity of MTP was the highest (83%), B/Y was the second (65%), and W/W was the lowest (48%). When B/Y and MTP were combined, the sensitivity was improved to 94% using parallel testing, and the specificity was improved to 87% using serial testing.Conclusions B/Y and MTP are valuable in diagnosis of early primary glaucoma, and the sensitivity and specificity of the diagnosis can be improved when B/Y and MTP are combined.

ObjectiveTo explore the clinical efficacy and surgical techniques of laparoscopic choledocholithotomy and primary suture. MethodsWe retrospectively analyzed the clinical data of 58 patients who underwent laparoscopic choledocholithotomy and primary suture between January 2009 and December 2014. ResultsAll the 58 patients underwent the surgery successfully. Operation time was 45-125 minutes, averaging 75 minutes. Intraoperative blood loss was between 10 and 50 mL with an average of 20 mL. Postoperative hospital stay was 5-14 days with an average of 7 days. Four cases of biliary leakage were cured by conservative treatment. ConclusionWith operation indications strictly grasped and skillful operation techniques, laparoscopic choledocholithotomy and primary suture are safe and reliable with a good curative effect.
ObjectiveTo investigate the guiding value of preoperative imaging and intraoperative rapid pathology in the diagnosis and treatment of pancreatic cystic neoplasm (PCN).MethodsThe clinical data of 205 patients with PCN diagnosed by pathology from July 14, 2003 to July 31, 2018 were analyzed retrospectively. The precise and fuzzy diagnostic rate and misdiagnosis rate of PCN by preoperative imaging and intraoperative rapid pathology were analyzed.ResultsThe most commonly used preoperative imaging methods were ultrasound and CT, in 146 cases (82.95%) and 141 cases (80.11%), respectively. There were 54 cases (30.68%) with MRI. Of them, 47 cases were examined by single examination, 129 cases received combined examination, of which 123 cases (95.35%) were examined by ultrasound combined with CT. The precise and fuzzy diagnostic rate of PCN by ultrasound, CT, and MRI were 81.51% (119/146), 81.56% (115/141), and 87.04% (47/54), respectively. Comparison of ultrasound with CT and MRI showed statistical significance (χ2=47.747, P<0.001; χ2=11.873, P=0.018), but no significant difference was observed between CT and MRI (χ2=5.012, P>0.05). In 27 cases of false diagnosis by ultrasound, no obvious abnormality was found in 14 cases (51.85%), followed by misdiagnosis as pancreatic pseudocyst (11 cases, 40.74%). Of the 26 cases misdiagnosed as pancreatic cancer by CT, 57.69% (15 cases) were misdiagnosed as pancreatic cancer; 7 cases were misdiagnosed by MRI, 42.86% (3 cases) of patients were misdiagnosed as pancreatic cancer and pancreatic pseudocyst. Thirty-one cases were misdiagnosed by intraoperative rapid pathology, and most of them misdiagnosed as pancreatic pseudocyst (10 cases, 32.26%). The next was SPN misdiagnosed as pancreatic neuroendocrine tumor (7 cases, 22.58%). The precise and fuzzy diagnostic rates of PCN were 81.58% (124/152), 86.84% (132/152), and 97.37% (148/152) in preoperative imaging, intraoperative rapid pathology, and preoperative imaging combined with intraoperative rapid pathology, while the misdiagnostic rates were 18.42% (28/152), 13.16% (20/152), and 2.63% (4/152), respectively.ConclusionsIn preoperative imaging and intraoperative rapid pathological examination, it is possible that ultrasound could not find PCN lesions. CT and MRI are most likely to be misdiagnosed as pancreatic cancer. Intraoperative rapid pathological examination misdiagnosed as pancreatic pseudocyst is most common. Perfect preoperative imaging and rapid intraoperative pathology can improve the correct diagnosis rate of PCN and avoid unreasonable surgical intervention measures.
