Objectives: To evaluate the efficacy of phacoemulsification and foldable IOL implantation with limbal tunnel incision.　Methods: A 3.2mm limbal tunnel incision was made on 72 eyes of 66 patients with senile, complicated and traumatic cataract. Phacoemulsification and foldable IOL implantation was performed. Visual acuity, corneal curvature and corneal topography were measured after the surgery.　 Results: One day, one week and one month after the surgery, visual acuity exceeded 0.5 in 69.4%, 80.6%,86.1% of the patients respectively. One week after the surgery, the mean astigmatism was (1.85±0.89)D(P<0.01), 0.30 D more than that before the surgery. Corneal topography showed that the incision was steep or flat. One month after the surgery, the mean astigmatism was (1.48±1.02)D，P>0.05,corneal topography had recovered.　 Conclusions: Phacoemulsification and foldable IOL implantation with limbal tunnel incision have comparatively simple, with less postoperative inflammation and faster recovery of visual acuity.

Objective:To explore the depression of patients with systemic lupus erythematosus (SLE) during the coronavirus disease 2019 (COVID-19) pandemic.Methods:Patients with SLE and healthy subjects(control group) from August 16, 2020 to September 2, 2020 in Urumqi, Xinjiang were collected. The depression and sleep quality were assessed by Self rating Depression Scale (SDS) and Pittsburgh sleep quality index (PSQI). The nonparametric data were represented by median (quartile spacing), and the rank sum test was used to compare the continuous variables between the two groups. Pearson correlation test was used for continuous variables, and Spearman correlation test was used for rank variables or classified variables. Statistical product and service solutions.Results:The prevalence rate of depression in the SLE group (41.9%) was significantly higher than that in healthy control group (32.1%). The difference was statistically significant ( χ2= 10.312, P<0.01). The prevalence rate of poor sleep in the SLE group (31.8%) was significantly higher than that in healthy control group (21.6%). The difference was statistically significant( χ2=3.885, P=0.049). The total score of VAS ( OR=1.366, P<0.01) , PSQI( OR=1.198, P<0.01) were the risk factor of depression in patients with SLE. Conclusion:SLE patients have a higher prevalence of depression during pandemic quarantinee-period, pain and poor sleep quality are risk factors. We need to pay attention to the psychological status of SLE patients.

OBJECTIVETo explore the clinical efficacy of moxibustion on rheumatoid arthritis (RA) in the patients and the impacts on the inflammatory indices.

METHODSForty RA patients were randomized into an observation group and a control group, 20 cases in each one. In the control group, diclofenac sodium sustained release tablets were used, 0.3 g each time, twice a day; methotrexate tablets were used, 10 mg each time, once a week; folic acid was used, 5 mg each time, once a week. In the observation group, on the basis of the treatment as the control group, moxibustion was added specially on the swelling and painful joints, once a day, 15-20 min each time till: the local skin turned slightly red. The treatment was given once a day, at the interval of 1 day after every 6 treatments. In the two groups, the efficacy was observed after 30-day treatment. Before and after treatment, the rheumatoid factor (RF), high sensitivity C-reactive protein (hs-CRP), erythrocyte sedimentation rate (ESR), disease activity score-28 (DAS-28) and the score of joint symptom and physical signs were observed.

RESULTSCompared with those before treatment, the levels of RF, hs-CRP, ESR, DAS-28 and the symptom scale score were all reduced in the RA patients of the two groups after treatment (all P < 0.05). Compared with the control group, the levels of RF, hs-CRP, ESR, DAS-28 and the symptom scale score in the observation group were improved much apparently (all P < 0.05). The total effective rate was 85.0% (17/20) in the observation group and was 80.0% (16/20) in the control group. The total effective rate in the observation group was apparently better than that in the control group (P < 0.05).

CONCLUSIONMoxibustion as supplement relieves the joint symptoms, reduces the inflammatory reactive indices and improves the clinical efficacy in the RA patients.

OBJECTIVETo compare the clinical effective differences between pricking blood combined with moxibustion and west medication for acute gouty arthritis.

METHODSForty patients with acute gouty arthritis were randomly divided into a pricking blood combined with moxibustion group (a combination group) and a western medication group, 20 cases in each one. In the combination group, pricking blood was used at the most painful points of the red turgid and painful joint once three days, total 3 times; moxibustion was applied at the same joint for 15-20 min, once a day. The moxibustion was adopted for 10 days. In the western medication group, 0. 3 g ibuprofen was prescribed orally twice a day for 10 days. The changes of uric acid (UA), high sensitivity C-reactive protein (hs-CRP), erythrocyte sedimentation rate (ESR) and the joint syndrome and symptom score before and after: treatment were observed. Results In the two groups, the UA, the hs-CRP, the ESR and the joint syndrome and symptom scores were lower than those before treatment (all P<0. 05). After treatment, the UA, the ESR and the joint syndrome and symptom scores in the combination group were declined more apparently than those in the western medication group (all P<0. 05). The total effective rate in the combination group was 85. 0% (17/20) which was better than 75. 0% (15/20) in the western medication group (P<0. 05).

CONCLUSIONPricking blood combined with moxibustion could improve the joint symptoms more effectively and the effect is better than ibuprofen orally.

Objective:Recent studies have shown that in contrast to decrease in distal gastric adenocarcinoma (DGA), incidence of adenocarcinoma of the esophagogastric junction (AEG) has increased noticeably in numerous counties. However, the reasons remain unclear. This study evaluated the possible differences in the expression of KLF4, SP1, and Cyclin D1 in AEG and DGA, and explored the potential carcinogenesis of AEG. Methods:Immunohistochemistry was performed on paraffin-embedded tissues to evaluate the pu-tative differences in the expressions of KLF4, SP1, and Cyclin D1 at protein level between AEG (n=58) and DGA (n=47). The patholog-ical significance of these markers between the two groups was also compared and analyzed. Results:The percentage of positive KLF4 expression was significantly lower in DGA than in AEG (P<0.05). Lower KLF4 expression was found both in well-or moderately dif-ferentiated cases and in poorly differentiated cases with DGA compared with their AEG counterparts (P<0.05). However, positive stain-ing for SP1 was significantly higher in DGA (P<0.05). No significant difference was found in the expression of Cyclin D1 between the two groups. Further analysis showed that in DGA, the positive expression of KLF4, SP1, and Cyclin D1 were significantly correlated with lymph node metastasis. In AEG, only Cyclin D1 expression was correlated with lymph node metastasis (P<0.05). No correlation was found among the expression of KLF4, SP1, and Cyclin D1 in AEG. In DGA, KLF4 was inversely correlated with SP1 and Cyclin D1 (r=-0.334 and r=-0.341, respectively, P<0.05), and SP1 was positively correlated with Cyclin D1 expression (r=0.340, P<0.05).Conclusion:Different expression patterns and clinicopathological significance of KLF4, SP1, and Cyclin D1 were observed between AEG and DGA, suggesting the putative difference in the carcinogenesis and progression of AEG and DGA.

Objective To investigate the correlation between toll-like receptor 9 (TLR9) gene 2848G/A polymorphism and primary antineutrophil cytoplasmic antibodies (ANCA) associated small vasculitis (AAV). Methods A case-control study was performed among 135 patients diagnosed with AAV and 140 disease-free control and we test the serum biochemical parameter. Polymorphism was analyzed by polymerase chain restricted fragments length polymorphism. As for statistic method, according to the character of data, we performed t-test, chi-square test, Spearman grade related analysis and one-way ANOVA. Results ① The frequencies of AA, GG, GA genotype of TLR9 2848 in AAV patients were 14.07%, 38.52%, and 47.71%, respectively; ② Significant increase in IgM was observed in AA genotype than GG+GA genotype in AAV patients (F=4.561, P<0.05). ③ There was no significant difference between AI and CI in AA, GA and GG genotype in AAV patients (F=2.115, 0.760, P>0.05). Conclusion AA, GA and GG genotypes are detected in TLR9 2848G/A in patients with AAV in Guangxi, without significant correlation with susceptibility to primary AAV in Guangxi.
