Objective To investigate the variations of intestinal flora of common carp in patients with hyperuricemia in Qingdao District.Methods The fecal flora was analyzed by gradient dilution method.The levels of uric acid in blood and feces were detected by enzyme colorimetry method and phosphortungstic acid method,respectively.Results E.coli (7.58 ± 0.34,P ＜ 0.05),the total count of aerobian (7.76 ± 0.67,P ＜ 0.05),and bacteroides (2.75 ± 0.31,P ＜ 0.05) were significantly increased in hyperuricemia patients compared to controls.Bifidobacterium (5.38 ± 0.34,P ＜ 0.05) and lactobacillus (2.69 ± 1.48,P ＜ 0.05) were sig-nificantly decreased compared to controls.Concentrations of uric acid in blood and feces were both significantly higher in the patients relative to healthy controls.Decomposition capability was similar to healthy controls.Decomposition capability of uric acid revealed a close correlation with bifidobacterium and lactobacillus,respectively (r =0.565,0.328,P ＜ 0.05).Conclusions Intestinal dysbacteriosis was found by the analysis of fecal flora in patient with hyperuricemia in Qingdao district.Dysbacteriosis might participate in the process of hyperuricemia onset.

Background Vitretomy and lenstomy with silicone oil tamponade is an effective method for complicated vitreous retinopathy.The severe anisometropia after silicone retention is usually treated by two-point transscleral suture fixation for posterior chamber intraocular lens(IOL)implantation.In order to reduce the number and difficulty and complication of the operation,the surgical method should be improved.Objective The goal of this study was to observe the resuh of silicone oil removal combined with four-point trans-scleral suture fixation of posterior chamber IOL after vitrectomy.Methods A retrospective case-observational study design was adopted.Twenty eyes with silicone oil tamponade from 20 patients without lens and posterior capsule after vitrectomy were included in this study.Silicone oil removal with four-point trans-scleral suture fixation of posterior chamber IOL was performed.The anterior ocular inflammatory response,intraocular pressure,uncorrected and corrected acuities before and after operation,corneal endothelial cell counting and postoperative complications were observed and analyzed.Written informed consent was obtained from all patients prior to the operation.Results All of the operative eyes in this study showed improvement of visual acuity after operation.Of the 20 eyes,a visual acuity of ≥0.8 was seen in 2 eyes,0.6-0.7 in 6 eyes,0.3-0.5 in 8 eyes and 0.05-0.2 in 4 eyes 3 months after the removal of silicone oil.The uncorrected acuity postoperation was significantly improved in comparison with preoperation(H=10.147,P＜0.01),but no significant difference was found in the corrected acuity between preoperation and postoperation(X =2.089,P＜ 0.01).The number of the corneal endothelial cells was(2064±329)cells/mm2 before operation,and that after operation was(1987±269)cells/mm2,showing an insignificant change between them(t =1.660,P ＞ 0.05).No abnormality of IOL position was found in all 20 operated eyes.There was not serious postoperative complication in all 20 patients.Conclusions The combination of silicon oil extraction with four-point transscleral suture fixation IOL is effective in eyes without posterior capsule or lens after vitrectomy.It can reduce the operation time and improve the postoperative acuity and the quality of life of patients.

Objective To evaluate the effect of the combination of dexmedetomidine and sufentanil on monitoring anesthesia care during burr-hole surgery for patients with chronic subdural hematoma. Methods 96 pa-tients underwent burr-hole surgery for chronic subdural hematoma with MAC were randomly divided into two groups:Group D and Group DS (n=48 in each group). Local anesthetic block was started at least 10 min after DEX and sufentanil infusion. Ramsay sedation scale of the two groups was maintained to 3. Anesthesia onset time, hemo-dynamics, the amount of rescue midazolam or fentanyl, the time to first dose of rescue midazolam or fentanyl, the to-tal number of intraoperative patient movements, postoperative recovery time, patient and surgeon satisfaction scores, and the adverse events were recorded. Results Compared with group D, anesthesia onset time was significantly less in group DS (13.68 ± 3.13 vs. 11.82 ± 2.43 min, P=0.002). More patients in group D required rescue midazol-am to achieve RSS=3 compared with group DS (31.25%15/48 vs. 12.50%6/48, P=0.023). Compared with group D, significantly fewer patients in group DS required rescue fentanyl to relieve pain (10.42%5/48 vs. 27.08%13/48, P = 0.036). Additionally, the total dose of rescue fentanyl in group DS was significantly higher (89.48 ± 23.27 vs. 125.28 ± 33.52μg, P=0.000), and the time to first dose of rescue fentanyl was longer than group D(18.34 ± 4.45 vs. 14.34 ± 3.63 min, P=0.000). The total number of patient movements during the burr-hole surgery was higher in group D than group DS (35.42%17/48 vs. 16.67%8/48, P=0.036). The time to recovery for discharge from the PA-CU (time to an Aldrete score ≥ 9) was significantly shorter in group DS compared with group D (17.54 ± 5.92 vs. 12.57 ± 5.28 min, P=0.000). Results from the patient and surgeon satisfaction scores showed significant differenc-es favoring group DS (P<0.05). More patients in group D showed higher levels of the overall incidence of bradycar-dia (37.50% 18/48 vs. 18.75% 9/48, P = 0.041) and hypotension(37.50%18/48 vs. 14.58%79/48, P=0.011)com-pared with group DS. Conclusions Compared with DEX alone, DEX-sufentanil associated with fewer number of in-traoperative patient movements, less amount of rescue scheme, could be safely and efficiently used for MAC during burr-hole surgery for patients with chronic subdural hematoma.

Objective To analyze the MR imaging features of pyocephalus. Methods MR imaging features!of pyocephalus in 5 cases with clinically proved were analyzed retrospectively. All patients were undergone no-contrast MR imaging. 3 patients received diffusion weighted-imaging(DWI). Results In all five patients,the debris and pus with pus-fluid level were shown inside the lateral ventricle.The debris or pus was slightly hyperintense on T1WI, slightly hypointense on T2WI relative to cerebrospinal fulid(CSF). On DWI, the debris was hyperintense in 1 case and isointense in 2 cases.Conclusion The features of MR imaging of pyocephalus is specific. MR imaging is valuable in the diagnosis of pyocephalus.

Objective To introduce the transfer of anterolateral thigh flap with iliotibial tract in repair of massive skin and soft tissue defects of the forearm and reconstruction of extension or flexion of the forearm. Methods Eight cases of complicated raw wounds of the forearm were repaired with transfer of anterolateral thigh flap with iliotibial tract. Flexor tendons of 3 cases and extensor tendons of 5 cases were repaired with iliotibial tract. The axial vessel of the flap was used to rebuild blood supply of the hand. Results All the flaps survived completely. A follow-up ranging from 3 months to 2.5 years re- vealed that the reconstructed forearms were good in appearance and soft in texture and restored protective sensation. Affected limbs could perform extension or flexion. Total range of motion (TRM) of the hands was excellent in 6 cases and poor in 2. Conclusion Anterolateral thigh flap with iliotibial tract can not only repair soft tissue defects of the forearm, but also reconstruct the main extension or flexion of the forearm simultaneously.

Objective To study the clinicopathological characteristics and the prognostic factors in metastatic pancreatic tumor.Methods The clinical data of 32 patients with metastatic pancreatic tumors were retrospectively analyzed.The survival of the patients were evaluated with the KaplanMeier method.Univariate analysis was done by log-rank test.Results The primary foei of these32 patients included:9 lung cancer,6 renal cell carcinoma,5 gastric cancer,12 others.The median survival was 15.5 months in the radical surgery group (n 8),18 months in the cryosurgery group(n=3),8 months in the group with palliative bypass operation (n=9),6 months in the group with local radiotherapy (n=3),and 5 months in the group without treatment (n=9).Univariable analysis revealed the type of primary tumor,treatment of the primary tumor,interval between diagnosis of primary tumor and pancreatic metastases,localized pancreatic metastasis,and treatment of the metastatic pancreatic tumor were associated with prognosis.Conclusions Metastatic pancreatic tumors are rare.Long term survival can be achieved with pancreatic resection in a highly selected subset of patients according to the type of primary tumor.Therapeutic cryosurgery as a new minimally invasive,targeted and immunologic method needs to be further evaluated.

Objective To study the clinicopathological characteristics,diagnosis and treatment of patients with mucinous cystic neoplasms (MCNs) of the pancreas.Methods The clinical data of 42 patients with mucinous cystic neoplasms of pancreas were retrospectively analyzed.Chi-square test and independent sample t-test were used for statistical analysis.Results The mean age of the patients was 53.1 yeas (ranged from 29 to 78 y).There were 32 female (76.2％).The patients were divided into two groups according to symptoms (the symptomatic group and the asymptomatic group).There were significant differences in tumor size,tumor location,operation type,operation time and adhesions with the surrounding tissues between the 2 groups of patients.The patients were then divided into three groups according to pathological type.There were significant differences in age,tumor marker,tumor location,operation type,operation time,adhesions with the surrounding tissues,operative blood loss,and postoperative hospital stay among the 3 groups of patients.There was no tumour recurrence in the patients with cystadenoma.Patients with cystadenocarcinoma developed tumor recurrence at a mean of 16.4 months (range,0-50) and died of tumor recurrence even after radical surgery at a mean of 22.9 months (range,3-58).Conclusion MCNs were seen most commonly in middleaged women.The presence of symptoms was a sign of malignancy.Resection of the tumor in the early stage is the key in dealing with MCNs.

Objective To observe the improvement effects of Qingshen Granule on the life quality of chronic kidney disease (CKD) patients with damp-heat syndrome. Methods The CKD patients with damp-heat syndrome were randomly divided into experimental group and control group. The control group was treated with Western medicine, and the treatment group was treated with Qingshen Granules additionally for 12 weeks. SCr and eGFR were observed before and after treatment, and the life quality was investigated by KDQOL-SFTM1.3. Results Actually 156 cases were completed, including 77 cases in the treatment group and 79 cases in the control group. The total rate of curative effect was 81.82% (63/77) in teatment group, and (63.29%, 50/79) in control group, with significent difference (P<0.05). Multivariate linear regression analysis indicated that gender, education level, TCM syndrome score, CKD stage, eGFR and Hb level could affect the life quality. The scores of KDQOL-SFTM and its containing the MOS item short from health survey (SF-36) and kidney disease targeted areas (KDTA) were significantly improved after treatment in experimental group (P<0.05), while the scores in control group were with no significant improvement. The improving effects of PCS, and SPL, SLEEP, PS in KDTA in treatment group were significantly superior to those in control group (P<0.05). The scores of life quality in effective and stable cases increased significantly after treatment compared with before treatment (P<0.05). Conclusion Qingshen Granules can effectively improve the life quality of CKD patients with damp-heat syndrome, and the effect is not dependent on the improvement of laboratory indexes (renal function).
