AIM: To investigate clinical efficacy of two drug therapies ( acyclovir with prednisone acetate tablets, ganciclovir with prednisone acetate tablets and aspirin) for acute retinal necrosis syndrome.
METHODS: Thirty patients (40 eyes) with acute retinal necrosis syndrome in our hospital were randomly divided into group A and B. Group A was treated with acyclovir with prednisone acetate tablets, and group B was given ganciclovir with prednisone acetate tablets and aspirin. Clinical effects in the two groups were observed and compared.
RESULTS: After treatment, the overall response rate in group B (90%) was obviously higher than that in group A (70%), both of two regimens were effective, without significant difference (P>0. 05). There was no significant difference on the pre - treatment visual acuity between the two groups (P>0. 05). After different treatments, the visual acuity in group B was ≥0. 5 in 12 eyes, 0. 1≤and<0. 5 in 4 eyes, 0. 02 ≤ and < 0. 1 in 3 eyes, and no photosensitive in 1 eye. The visual acuity in group A was≥0. 5 in 9 eyes, 0. 1≤and<0. 5 in 3 eyes, 0. 02≤and<0. 1 in 6 eyes, and no photosensitive in 2 eyes. The recovery of visual acuity in group B was obviously better than that in A group ( P < 0. 05). The incidence of complications such as retinal tear, herpes, mouth ulcers, chickenpox, viral encephalitis and central nervous system diseases in group B (10%) was significantly lower than that in A group (35%,P<0. 05).
CONCLUSION: Two drug therapies ( acyclovir with prednisone acetate tablets, ganciclovir with prednisone acetate tablets and aspirin ) both have positive therapeutic effect, but the latter can better restore visual acuity and decrease the complications.

Objective: To investigate the effect of adhesion of Lactobacillus reuteri JCM1081 to enterocyte-like HT-29 cells on filamentous cytoskeleton.Methods:Cultured human intestinal enterocyte-like HT-29 cells were used.Cell permeability was examined in vitro by Evans blue labeled albumin and Examination of F-actin was conducted by direct immuno-fluorescence labeling using fluorescein labeled phalloidin.Results:Lactobacillus reuteri JCM1081 did not alter cell integrity and prevented the increase in permeability induced by enteropathogenic Escherichia coli infection.The distribution of F-actin were also not altered.Conclusion :Lactobacillus reuteri JCM1081 exerts a protective effect against the filamentous cytoskeleton rearrangement and permeability lesions promoted by enteropathogenic Escherichia coli infection.

Objective To detect the effects of bifidobacterium or bifidobacterium cultured supernatant on the mRNA expression of tumor necrosis factor receptor-associated factor 6 (TRAF6),glycogen synthase kinase-3β (GSK-3β) and the miRNA-146a in rat small intestinal epithelial cell(IEC-6) induced by lipopolysaccharide (LPS).Methods IEC-6 in logarithmic phase were randomly divided into LPS group,cultured supernatant group and inactivated bacteria group.All the 3 groups were exposed to 5 mg/L LPS for 5 hours,and then 1 mL sterile saline was added in LPS group and culturing continued for 24 hours ; 1 mL bifidobacterium cultured supernatant was added in cultured supernatant group and culturing continued for 24 hours;1 mL inactivated bifidobacterium 1 x 1010 CFU/L added in inactivated bacteria group and continued culturing for 24 hours.The mRNA expressions of TRAF6,GSK-3 β and miRNA-146a were detected by reverse transcription-polymerase chain reaction (RT-PCR).Results The level of TRAF6,GSK-3 β of culture supematant group (0.72 ± 0.05,0.46 ± 0.14) were all lower than LPS group (1.01 ± 0.14,1.02 ± 0.25),but the level of miRNA-146a(3.05 ± 0.40) was higher than that in LPS group(1.01 ± 0.12),and there were significant differences between them (t =5.278,6.316,13.218,P =0.000).The level of GSK-3 β of inactivated bacteria group(0.59 ±0.13) was significantly lower than that in LPS group(t =4.837,P =0.000).The levels of TRAF6 and miRNA-146a of inactivated bacteria group(1.05 ±0.11,0.78 ±0.22) had no significant differences with LPS group (t =0.732,1.463,P ＞ 0.05).The level of TRAF6 of cultured supernatant group was lower than that in inactivated bacteria group,and the level of miRNA-146a was higher than that in inactivated bacteria group,and there were significant differences between 2 groups (t =6.009,14.687,P =0.000).Conclusions Bifidobacterium cultured supernatant and inactivated bacteria both have certain protective effect on the IEC-6 induced by LPS.One of the protective mechanisms of bifidobacterium cultured supernatant may be achieved by elevating the expression of miRNA-146a,and decreasing the levels of inflammation related factor TRAF6 and damage related factor GSK-3β.The protective effects of inactivated bifidobacterium may be achieved by decreasing the level of damage related factor GSK-3β.

ObjectiveTo assess the value of the area of ground glass opacities (GGOs) in lungs displayed by high-resolution computed tomography (HRCT) in paraquat (PQ) poisoned patients in evaluating prognosis. Methods Clinical and imaging data of 137 patients with acute PQ poisoning admitted to Affiliated Hospital of the Medical College of Chinese People's Armed Police Forces from January 2012 to August 2014 were analyzed retrospectively. The plasma concentration of PQ on admission and the area of GGOs were compared between two groups. The lung HRCT within 10 days of poisoning was performed every 3 days, and the areas of GGOs were evaluated on five levels, including aortic arch, aortic pulmonary window, left upper lobe bronchial, right inferior pulmonary vein, and left diaphragmatic dome. Receiver operating characteristic curve (ROC) was plotted to evaluate the value of all the parameters for prognosis.Results Among 137 patients, 45 died within 28 days after poisoning, with the mortality rate of 32.85%. The plasma PQ level in the non-survivors was significantly higher than that in the survivors (mg/L:7.06±0.67 vs. 3.51±0.34,t = 5.280,P = 0.000). The areas of GGOs at three time points in the non-survivors were significantly higher than those in the survivors [1-3 days: (32.0±5.0)% vs. (2.5±0.4)%,t = 7.860,P = 0.000;4-6 days: (45.5±5.7)% vs. (2.8±0.5)%,t = 12.420,P = 0.000; 7-10 days: (68.0±4.8)% vs. (3.0±0.6)%, t = 23.950,P = 0.000]. ROC analysis demonstrated that the area under the ROC curve (AUC) of GGOs in 7-10 days was 1.000, which could be used to determine the prognosis, but it was too late for the treatment. The AUC of GGOs in 4-6 days was 0.979, with the threshold of> 12.0%, the specificity of 96.15%, the sensitivity of 85.19%, the positive predictive value of 88.46%, and the negative predictive value of 94.94%, which presented good effect in predicting prognosis in the early stage of acute PQ intoxication. But plasma PQ concentration was relatively poor for determining prognosis, AUC was 0.821, with the threshold of> 1.95 mg/L, the specificity of 34.52%, the sensitivity of 88.64%, the positive predictive value of 41.49%, and the negative predictive value of 85.29%.Conclusions The area of GGOs displayed by HRCT can be used to evaluate the fully developed acute PQ lung injury, and it is superior to plasma PQ concentration. The area of GGOs displayed by HRCT 4-6 days after intoxication can be used for the evaluation of PQ induced pulmonary injury in the early stage and the evaluation of clinical prognosis.

Objective To investigate the relationship between personal disposable income and female depression,and to examine the moderating roles of personality in this link.Methods The demographic questionnaire,self-rating depression scale (SDS) and eysenck's personality questionnaire short scale (EPQ-RSC) were used to survey 139 cases of married female patients with depression.Results Personal disposable income could be used to significantly and negatively predict female depression(β=-0.669,P＜0.01).The interaction between personal disposable income and introversion-extroversion,personal disposable income and neuroticism was significant (β=0.142,P＜0.05.β=-0.232,P＜0.01).In the groups of higher and lower scores on the introversion-extroversion dimension,personal disposable income could be used to significantly predict female depression(β=-0.397,P ＜0.05.β=-0.452,P＜0.05).In the group of higher scores on the neuroticism dimension,personal disposable income could be used to significantly predict female depression(β=-0.553,P＜0.01),but not in the group of lower scores(β=-0.349,P＞0.05).Conclusion Personal disposable income has significantly negative prediction effect on female depression,and introversion-extroversion and neuroticism have significant moderating effects on the relationship between personal disposable income and female depression.

Objective To explore the correlation between postoperative cognitive dysfunction (POCD)and serum level of S100βand NSE in patients undergoing on-pump heart valve replacement. Methods Ninety-eight patients underwent elective heart valve replacement were enrolled and divided into two groups:POCD group (group P)and none POCD group(group NP)by the result of neurocog-nitive testing with MMSE performed preoperatively and on the first postoperative day.Serum S-100βprotein and NSE were measured before operation(T0 ),at the end of operation(T1 ),24 h(T2 )and 48 h(T3 ) postoperatively.Results The incidence of POCD on the first postoperative day was 45 (45.9%).Compared with T0 ,the S100βincreased at T1 in both groups (P <0.05),NSE increased at T1 and T2 in both groups,and NSE increased in group NP at T3 (P <0.05).There was no signifi-cant difference of NSE between groups P and NP.The prolonged recovery time(OR = 1.222,P =0.004)and increased concentration of S100βat the end of operation(OR=1.85,P =0.009)were pre-dictors of POCD on the first postoperative day.Conclusion There was a higher incidence of POCD af-ter on-pump heart valve replacement surgery.The prolonged recovery time and increased concentra-tion of S100βat the end of operation might be predictors of POCD.

Objective To observe the clinical efficacy of Tanreqing Injection combined with levofloxacin injection in treatment of acute episode of chronic bronchitis and its effect on bacterial clearance rate. Methods Totally 66 patients were randomly divided into treatment group and control group (33 cases for each). Both groups were given expectorant and antispasmodic treatment. The treatment group was given Tanreqing Injection combined with levofloxacin injection, while the control group was given levofloxacin injection only. The treatment course was 12 days. The clinical symptoms, signs, and sputum culture before and after treatment were observed. The clinical efficacy and the bacterial clearance rate of the two groups were compared. Results The markedly effective cases and the effective cases in the treatment group were 15 and 29 respectively, and those in the control group were 7 and 21 respectively, with statistical significance (P<0.05). The bacterial clearance rate was 89.5% (17/19) in the treatment group, while 55.6%(10/18) in the control group, with significant difference (P<0.05). Conclusion Acute episode of chronic bronchitis treated by Tanreqing Injection combined with levofloxacin injectcion is more effective than levofloxacin injection only.

Objective To evaluate the feasibility and application of histopathology diagnosis of endometrial tissues obtained by endometrial cell collector (Jingyou, SAP-1). Methods One hundred and ninety-three patients whose endometrial lesions should be excluded were selected. First, endometrial tissue were obtained from the patients by Jingyou, then they underwent comprehensive curettage under hysteroscopy. The histopathology diagnosis was performed respectively. The specimen satisfaction rate and diagnostic accuracy was analyzed and compared. Results The specimen satisfaction rate of curettage under hysteroscopy was 95.85%(185/193). The specimens of 8 cases were not satisfied because the tissues were not enough. The specimen satisfaction rate of Jingyou was 82.38% (159/193). The specimens of 34 cases were not satisfied, among whom in 10 cases scratches did not throughout the whole palace antrum, and in 24 cases tissues quality were poor. The endometrial thickness in unsatisfactory specimen by Jinyou was significantly thinner than that in satisfactory specimen:(0.64 ± 0.18) cm vs. (0.97 ± 0.43) cm, and there was statistical difference (P<0.05). The diagnostic accordance rate between Jingyou and curettage under hysteroscopy was 79.87%(127/159). The sensitivity of Jingyou from high to low was 94.19% (81/86) in normal menstrual endometrial, 7/10 in endometrial carcinoma/ atypical hyperplasia, 67.86%(38/56) in endometrial hyperplasia and 1/7 in endometrial polyps. Missed diagnosis of jingyou inluded 2 cases of endometrial carcinoma and 4 cases of endometrial atypical hyperplasia. The misdiagnosed rate of high grade endometrial lesions was 6/16, and the patients were misdiagnosed because the tissues were not enough. Four cases of endometrial atypical hyperplasia had underwent conservative treatment of repeated curettage. Conclusions Application of Jingyou can obtain micro endometrial tissues, and the accordance rate of histopathology diagnosis is high with curettage under hysteroscopy. When the collector makes a comprehensive collection to the uterine cavity specimen, it can accurately screen endometrial carcinoma and atypical hyperplasia. The patients who have endometrial atypical hyperplasia and receive conservative treatment and curettage repeatedly curettage, thin endometrium and ultrasonic highly suspected endometrial polyps, are not recommend to use Jingyou to obtain specimen. When the specimen is not satisfied using the collector, additional hysteroscopy should be performed to avoid misdiagnosis of high grade endometrial lesions.

Objective By simulating a high-glucose condition of peritoneal dialysis (PD)fluid,to explore the effect of high glucose on the expression of leptin and its relationship with peritoneal angiogenesis.Methods Adipocytes differentiated from 3T3-L1 were divided into high glucose group (139 mmol/l glucose) and high mannitol group.Leptin levels in supernatant collected at 0 h,12 h,24 h and 48 h were measured by ELISA.Endothelial cells (ECs) were respectively cultured with normal glouse,high glucose,high mannitol condition,supernatants of adipocyte induced by normal glouse,high glucose and high mannitol,high glucose supernatants+leptin antibody,and high mannitol supernatants + leptin antibody.Tubular structure formation and migration of ECs were detected.Results Adipocytes exposed to high glucose for 48 h produced more leptin as compared with control group,high mannitol group,12 h-high glucose group and 24 h-high glucose group (all P ＜ 0.05).Compared with ECs in normal group,ECs in high glucose had less tubular structure formation and increased migration (all P ＜ 0.01).Compared with those of ECs in high glucose,the tubular structure formation and the migration of ECs in adipocyte supernatants induced by high glucose had increased (all P ＜ 0.01),and these effects were reduced by leptin antibody (all P ＜ 0.01).Conclusion There is an up-regulation of leptin in adipocytes exposed to high glucose,which may be an alternative way to prevent peritoneal angiogenesis.
