AIM:To perform a new method for orbital implant and contracted socket through one time and its results. ·METHODS:Totally 114 patients 114 eyes, from January 2008 to June 2014, with contracted socket participated in this study. We incised the bulbar conjunctiva horizontally and excised scar tissue, then implanted the hydroxyapatite in the four extraocular muscles and tightly sutured the Tenon ' capsule. After that, we put the superior and inferior conjunctival petals backwards and sutured them to the Tenon ' s capsule. All the patients were divided into four groups according to the vertical diameter length of the conjunctival defect area:GroupⅠ:≤5mm; Group Ⅱ: 6-10mm; Group Ⅲ: 11-15mm; and Group Ⅳ: ≥16mm. These patients were followed up for 6mo to 3y to observe the conjunctival sac shaping and growth of conjunctiva. ·RESULTS:There were 64 cases in GroupⅠ, 31 cases in Group Ⅱ, 16 cases in Group Ⅲ and 3 cases in Group Ⅳ. All patients ' conjunctival defect was covered by new conjunctiva and scar tissue 4 to 6wk after surgeries. Ten cases had contracted socket; 2 cases had orbital implant exposure, requiring reoperation. Of the 114 cases, 8 had contracted socket and could use a smaller conformer, 106 could use a normal size conformer. ·CONCLUSION: When the conjunctival defect was ≤15mm, this new method can address the orbital implant and contracted socket at the same time. While it was ≥16mm, flap transplantation is necessary.

Objective To evaluate the effect and pathological characters for patients with early esophageal carcinoma and intraepithelial neoplasia after endoscopic submucosal dissection (ESD). Methods 69 patients from January 2013 to January 2016 were treated with ESD at the early stage of esophageal carcinoma and intraepithelial neoplasia. The clinical features and the size of the lesions of all the patients were collected. Then analyzed postoperative complications and pathological characteristics. Results Among 69 cases, 16 were early esophageal cancer, 38 were high-grade esophageal neoplasia and 35 were low-grade esophageal neoplasia. The whole piece resection rate was 100.00 % (69/69), complete resection rate and curative resection rate was 95.65 % (66/69), respectively. The largest removal diameter is 7.0 cm. Biopsy accuracy was 69.57 % (48/69). Compared with biopsy, diagnostic accuracy with ESD specimens is higher. Conclusion The early esophageal carcinoma and intraepithelial neoplasia can be treated with ESD. ESD can resect lesions primarily, provide complete specimen for further pathological assessment and improve diagnostic accuracy.

Streptomyces sp. A048 was cultured in a complete medium to the last stage of log phase,the hyphae were washed and collected by centrifugation. Then the hyphae were inoculated in liquid medium for chitinase production using two-step fermentation. Activity of chitinase produced by two-step fermentation was 1.1 times higher than that from one-step fermentation,and ferment cycle was for 54 hours,which was 66 hours shorter than that of one-step fermentation. The hyphae and the powder of chitin were co-immobilizated and cultured in liquid medium for 36 hours,activity of chitinase was 1.8 times higher than that from one-step fermentation,and ferment cycle was 54h shorter than that of one-step fermentation. By adding 0.4% cellulose to two-step fermentation,activity of chitinase was 18.52 U/mL that was 4 times higher than that from the control and 10 times higher than that from one-step fermentation. Two step fermentation with chitin and cellulose may be the optimal fermentation process to produce Chitinase from Streptomyces sp. A048.

This study is to investigate the effect of ethyl gallate on invasion capabilities and its mechanism of breast cancer MDA-MB-231 cells. Using cell adhesion and transwell assay, separately, the effects of ethyl gallate on the invasion of MDA-MB-231 cells were measured. The Akt-NF-κB signal pathway protein expressions were analyzed with Western blot. Also, the mRNA levels of MMP-9 and MMP-2 were analyzed by RT-PCR. Ethyl gallate inhibited the abilities of motility, adhesion and invasion of breast cancer MDA-MB-231 cells in vitro (P<0.05), inhibited the mRNA levels of MMP-9, MMP-2, phosphorylation of AKt and protein expression of NF-κB. It is concluded that ethyl gallate can inhibit the abilities of invasion of breast cancer in vitro by inhibiting the mRNA levels of MMP-9/MMP-2, phosphorylation of Akt and protein expression of NF-κB.

Objective To evaluate the efficiency and clinical value of modular flexible ureteroscope combined with Holmium laser lithotripsy for treatment of renal calculi. MethodsA total of 46 patients with renal calculi were treated with modular flexible ureteroscope combined with Ho:YAG lithotripsy in our hospital from December 2009 to May 2011.There were 19 cases in middle and upper calyx,8 cases in lower calyx,15 case in renal pelvic,and 4 cases in multiple calyxes.The calculi diameter ranged from 6mm to 31 mm (average in 15 ± 7.9 mm).Flexible ureteroscope was used to find renal calculus under epidural anesthesia,and Holmium laser lithotripsy was used at a maximum energy of 12 to 20W (0.8 - 1.0 J/15 -20Hz).F5 or F6 double-J tubes and catheters were indwelled routinely postoperatively.-examine with KUB and removethe catheter 2 days after operation.Re-examine with B-ultrasonography or KUB 4 weeks after op-eration to evaluate the stone free rate.Residual stones ≥4 mm were regarded as clinical significance of residual stone fragments. Results 45 operations were successful except one case changed to percutaneous nephrolithotomy (PCNL) because of ureteral stricture.The operation time was 45 -150 min (average in 110.4 ±25.3 min).The patients were discharged from hospital in 2 -5 days(average in 3 days) after operation.The stone detection rate was 95.6％ (44/46),and the stone free rate was 86.9％ (40/46) after one operation. No severe complications such as ureteral perforation or hemorrhea occurred. Conclusions Modular flexible ureteroscope combined with Holmium laser lithotripsy is effective and safe for treatment ofrenal calculi,meanwhile it can decrease the high maintenance costs of integrated flexible ureteroscope.

Objective To explore the changes in inflammatory reactions in tail-suspension mice infected by Klebsiella pneumoniae from spaceflight.Methods Tail suspension was used to simulate the physiological effects of microgravity.C57BL/6 mice were randomly divided into control (Con),control+K.pneumoniae T16-169 (Con+T16-169),tail suspension (TS) and tail suspension+K.pneumoniae T16-169 (TS+T16-169) groups.The level of inflammatory cytokines TNF-α,IL-6 and IL-1β mRNA in lung tissue and the plasma cytokine concentration were detected by RT-qPCR and xMAP technology,and HE staining was used to represent the morphological changes in lung tissue.Results Compared with the control group,the expression of inflammatory cytokines in lung tissue and plasma concentrations of all experimental groups were increased,and the difference in TS+T16-169 group was the most significant (P<0.01 or P<0.001).HE staining showed that the lung tissues in Con+T16-169 and TS+T16-169 groups were damaged in different degrees,and the damage of TS+T16-169 group was the most serious.Conclusion The K.pneumoniae from spaceflight significantly increases the expression of inflammatory cytokines in lung tissue and plasma concentrations after infecting tail-suspension mice,and induces more serious damages to the lung tissue,which suggests that inflammatory reactions can be increased in tail suspension mice infected by K.pneumoniae from spaceflight.

Objective Obesity is one of the risk factors for gout.The aim of the present study was to evaluate clinical characteristics of gout patients with different BMI.Methods A total of 5 104 patients with gout were enrolled and divided into three groups according to the BMI.The clinical information was collected and relevant biochemical indices were detected.SPSS software was applied for the statistical analyses.Results There were significant differences in the ratios of gender,regular exercise,hypertension,tophus,renal insufficiency,hyperlipidemia,impaired glucose metabolism,liver dysfunction among the three groups (all P＜0.01).The onset age in overweight [45(36,55) years] and obese subjects [40(31,50)years] were earlier than that of the normal weight subjects [50 (38,61) years].Moreover,waist circumstances [103(99,108) cm and 94 (90,98) cm vs 87 (82,91) cm],systolic pressure [130 (120,145) mmHg (1 mmHg =0.133 kPa) and 130 (120,140) mmHg vs 128 (115,140) mmHg],diastolic pressure [90 (80,100) mmHg and 85 (80,92) mmHg vs 80 (79,90) mmHg],fasting blood glucose [5.77 (5.30,6.44) mmol/L and 5.65 (5.19,6.26) mmol/L vs 5.55 (5.10,6.15) mmol/L],TG [2.10 (1.46,3.04) mmol/L and1.88 (1.35,2.78) mmol/L vs 1.52 (1.07,2.39) mmol/L],TC [5.20 (4.55,5.93) mmol/L and 5.07 (4.46,5.75) mmol/L vs 4.95 (4.27,5.65) mmol/L],serum uric acid [483(418,552) μmol/L and461(395,524) μmol/L vs440 (368,517) μmol/L],ALT [30 (21,46) U/L and25 (18,36) U/L vs 21 (14,29) U/L],AST [21(17,28) U/L and 20 (17,26) U/L vs 20 (6,25) U/L],the number of joints involved [2 (1,3) joints and 2 (1,2) joints vs 1 (1,2) joints] in the overweight and obese groups were higher than those in the normal weight group (all P ＜ 0.01).There were no statistical differences in family history,involvement of upper limb joints,kidney stones and coronary heart disease among the three groups (all P ＞ 0.05).Conclusions Obesity is associated with an earlier age of gout onset.With the increase of BMI,the blood pressures,glucose,lipid,serum uric acid,liver transaminase levels and the number of involved joints increased gradually.Cautions should be taken in treating patients with different BMI.
