?AlM: To evaluate the clinical efficacy of posterior continuous curvilinear capsulorhexis ( PCCC ) combined with anterior vitrectomy in preventing posterior capsule opacification of congenital cataract surgery.
?METHODS:Postoperative clinical follow-up data of 82 cases ( 87 eyes ) with congenital cataract treated in Eye Center of our hospital from January 2011 to August 2014 were retrospectively analyzed. The patients were divided into the surgical control group ( 38 cases, 40 eyes, recieved phacoemulsification + PCCC ) and the study group ( 44 cases, 47 eyes, accepted phacoemulsification+ PCCC + anterior vitrectomy). The incidence of central optic axis opaque and postoperative visual acuity distribution were recorded at 1a follow - up. lntraoperative and postoperative complications were observed.
?RESULTS:The rate of central optic axis opaque grade 0 in control group was 37. 5%, compared to 76. 6% in study groups. The opacity distribution ratio of grade 1,2,3 and 4 in study group were lower than that of control group, and the central optic axis opacity distribution ratio in study group was significantly better than that of control group (P<0. 05). The 19 eyes(47. 5%) of visual acuity testing ≤0. 5 in control group , was higher than the 7 eyes(14. 89%) of that in the study group, The 21 eyes (52. 5%) of visual acuity testing >0. 5 in control group was lower than the 40 eyes ( 85. 11%) of that in study group. The visual acuity between two groups has statistical significance difference after 1a follow-up ( P<0. 05 ) , and the visual acuity in study group was significantly better than that in the control group. The postoperative intraocular pressure at 1mo and 1a follow-up was lower than before operation in two groups ( P<0. 05), but there was no significant difference between two groups in intraocular pressure (P<0. 05).
?CONCLUSlON: Combination of phacoemulsification, PCCC and anterior vitrectomy presents reliable clinical effects on postoperative central optic axis opacity distribution ratio and visual acuity, and it should be adopted to prevent the occurrence of posterior capsule opacification.

Abstract: Objective To analyze the spatial-temporal characteristics of the active pulmonary tuberculosis (PTB) and the pathogenic positive PTB in Fuling District of Chongqing during the 13th Five-Year Plan period, so as to explore the clustering areas, and provide scientific basis for the precise prevention and control of tuberculosis in Fuling District. Methods The PTB registration data of 27 townships in Fuling District from 2016 to 2020 were collected. The descriptive analysis were used to describe the temporal and spatial distribution characteristics of patients, SaTScan9.0 and ArcGis10.6 was used for spatial-temporal scanning analysis and local auto-correlation analysis. The results were visualized by ArcGis10.6. Results A total of 4 038 case of active PTB patients were registered and a downward trend was observed in PTB during the 13th Five-Year Plan period in Fuling District. The average annual registration rate of PTB was 70.17/100 000, and the annual PTB registration rate declined by 8.21%. The peak of active PTB and etiological positive PTB were mainly concentrated in March and June respectively. The top five streets of cumulative active PTB patients registered were Lizhi street, Dunren street, Chongyi street, Ma 'an street and Jiangdong street, accounting for 60.18% of the total registered PTB patients during the 13th Five-Year Plan period. The top three average annual registration rates were Dunren street (101.35/100 000), Chongyi street (101.34/100 000) and Wulingshan Township (99.21/100 000). The registered PTB from 2016 to 2020 showed a global auto-correlation (Moran's I=0.64, P<0.0001). The "high-high" area of active PTB and the etiological positive PTB all covered Lizhi street, Jiangdong street and Longqiao street. By scanning analysis of spatial-temporal, the primary cluster of active PTB concentrated in the main urban area south of the Yangtze River in Fuling during January 2016 to December 2017, and the primary cluster of pathogenic positive PTB concentrated in the main urban area south of the Yangtze River in Fuling and Jiangdong street during January 2019 to December 2020. Conclusions During the 13th Five-Year Plan period, there was the spatial-temporal clustering of PTB in Fuling District, which mainly gathered in the main urban area south of the Yangtze River in Fuling district and surrounding streets centered on Lizhi street.

Objective To evaluate the possible interactions among different impact factors possibly affecting the treatment efficacy of 131I in Graves′ disease (GD). Methods Six hundred and thirty two GD patients that had been treated by 131I, with or without antithyroid drugs (ATD), were included in this study. The impact factors were pre-defined as age (x1), sex (x2), mass of thyroid (x3), course of disease (x4), initial symptom (x5), condition of disease (x6), ATD treatment duration (x7), effective half life time (x8), maximum 131I uptake rate (x9), total dose of 131I (x10), dose of 131I per gram of thyroid (x11), TRAb (x12), TSI (x13), TgAb (x14), and thyroid microsomal antibody(TMAb) level(x15). Interactions among different impact factors were studied by t-test, χ2 test and multi-variant logistic regression. Results Age, mass of thyroid, ATD treatment duration, maximum 131I uptake rate, dose of 131I per gram of thyroid tissue and TSI level were identified as independent impact factors affecting the 131I treatment efficacy on GD (χ2=6.908, t=-4.063, χ2=13.558, t=-2.553, t=4.528, χ2=9.716, all P<0.05) by uni-variant and multi-variate analyses. Loglinear and general linear model analyses showed that there existed multiple multiplicative and additive interactions among the factors of age, mass of thyroid, ATD treatment duration and maximum 131I uptake rate (likelihood χ2=8.176, P>0.05; F=2.928, 1.992, 2.629, 2.215, all P<0.05), which indicated that the treatment efficacy with co-existing multiple factors was not equal to simple summation of single factors. Conclusions The interactions among multiple factors can cause indi-rect effect on 131I treatment, which might guide the prescription of 131I dosage for GD treatment.

OBJECTIVETo evaluate the efficacy and safety of etanercept plus Tripterygium wilfordii polyglycoside (TWP) in elderly patients with active rheumatoid arthritis (RA).
METHODSTotally 46 elderly patients with active RA were randomly assigned to the treatment group (22 cases) and the control group (24 cases). All patients received subcutaneous injection of etanercept, 25 mg each time, twice per week. The dosage was reduced to once per week 3 months later. Patients in the treatment group took TWP Tablet (10 mg each time, three times per day), while those in the control group took methotrexate (MTX), 10 mg each time, once per week. The whole course lasted for 24 weeks. Patients' rest pain, tender joint number, swollen joint number, health assessment questionnaire (HAQ), patients' global assessment, physicians' global assessment, erythrocyte sediment rate (ESR), C reactive protein (CRP), rheumatic factor were assessed at week 0, 4, 8, 12, and 24. The curative effect was statistically evaluated by the United States Institute of Rheumatology ACR20, ACR50, and ACR70 improvement criteria. Meanwhile, any adverse event was recorded and evaluated.
RESULTSTotally 41 completed the trial, and 5 dropped off (3 in the treatment group and 2 in the control group). Compared with the control group, there was no statistical difference in ACR20, ACR50, or ACR70 in the treatment group (P > 0.05). Compared with before treatment in the same group, there was some improvement in tender joint number, swollen joint number, visual analogue scale (VAS) for patients' global assessment, VAS for physicians' global assessment, ESR, CRP, and HAQ between the two groups, showing statistical difference (P < 0.05). Compared with the control group in the same phase, there was no statistical difference in the treatment group (P > 0.05). There was no statistical difference in the occurrence of adverse events between the two groups.
CONCLUSIONSEtanercept plus TWP could achieve equivalent therapeutic effect to that of Etanercept plus MTX. The two regimens could improve clinical signs, symptoms, and QOL related to RA. They were well tolerated in the treatment of elderly patients with active RA.

ObjectiveTo compare the predictive value of anatomic scoring system, physiological scoring system, and the combination of two systems in death prediction of patients with severe trauma in intensive care unit (ICU). Methods A retrospective analysis of patients with severe trauma admitted to department of critical care medicine of Daping Hospital, the Third Military Medical University, and Zunyi Medical University from January 2011 to December 2014 was conducted. The patients meeting the following criteria were enrolled: over 16 years old, admitted to hospital shorter than 24 hours after trauma, length of ICU stay≥48 hours, and injury severity score (ISS)≥16. Patients were divided into two groups: survivors and non-survivors. The data of anatomic scoring system, including ISS and new injury severity score (NISS), and physiological scoring system, including acute physiology and chronic health evaluationⅡ(APACHEⅡ) score were collected. The predictive power for death of the scoring system alone or combination in patients with severe trauma was evaluated.Results A total of 614 patients with severe trauma were enrolled, and there were 153 deaths with a mortality rate of 24.9%. ISS, NISS, APACHEⅡ, ISS+ APACHEⅡ, NISS+ APACHEⅡ of non-survivors were significantly higher than those of survivors (ISS: 29.15±7.75 vs. 24.31±6.50, NISS: 41.96±12.01 vs. 29.64±8.19, APACHEⅡ: 23.71±6.58 vs. 17.02±5.49, ISS+ APACHEⅡ: 52.86±10.00 vs. 41.33±8.70, NISS+ APACHEⅡ: 65.67±13.46 vs. 46.66±10.43, allP< 0.01). The area under receiver operating characteristic curve (AUC) of ISS, NISS, APACHEⅡ, ISS+ APACHEⅡ, NISS+ APACHEⅡ was 0.687, 0.792, 0.782, 0.809, and 0.860, respectively. Both of ISS+ APACHEⅡ and NISS+ APACHEⅡ had higher AUC than that of ISS, NISS or APACHEⅡ alone; and the AUC of NISS+ APACHEⅡ was significantly larger than that of ISS+ APACHEⅡ(allP< 0.05). NISS+ APACHEⅡ showed the largest AUC in death prediction of severe trauma patients. The cut-off value, sensitivity, specificity, positive predict value (+PV), negative predict value (-PV), positive likelihood ratio (+LR), negative likelihood ratio (-LR), and Youden index of NISS+ APACHEⅡ, which had the greatest AUC, were 56, 75.2%, 82.0%, 58.1%, 90.9%, 4.17, 0.30, and 0.572, respectively.Conclusion The combination of anatomic scoring system and physiological scoring system is better than single scoring system for death prediction in patients with severe trauma in ICU, and it may be considered to be a new method for early identification of death risk in patients with severe trauma.

OBJECTIVETo isolate and identify the pathogen of Dengue fever from Shenzhen city in 2005 - 2006, and to analyze the molecular characteristics of the isolated Dengue virus strain as well as to explore its possible origin.
METHODSIgM and IgG of serum samples taken from 60 suspected Dengue fever patients were detected by ELISA and immunochromatography, and 9 specimens were positive. Nine samples from patients with early stage Dengue fever were used to isolate virus with C6/36 cell line and the positive cell cultures were identified by MGB fluorescent PCR. The type of isolated virus strain was determined by RT-semi-nested-PCR and fluorescent PCR. E gene of isolated virus strain was amplified by RT-PCR and sequenced. Homology and phylogenetic tree of E gene of Shenzhen Dengue virus with the strains isolated from other areas were constructed.
RESULTSOf nine antibody-positive serum samples, one strain of Dengue virus was successfully isolated. The isolated virus strain was confirmed as Dengue virus type 2 and designated as DEN2-SZ0521. The homology of nucleotide sequence and the deduced amino acid sequence of E gene of SZ0521 with standard type 2 Dengue virus NGC strain was 94.2% and 98.2%, but the homology with standard Dengue virus 1, 3, 4 in the same fragment were 59.1%, 57.2%, 58.5% and 68.1%, 66.7%, 63.2%, respectively. The phylogenetic tree indicated that SZ0521 had the greatest similarity with the Malay0412a/Tw strain and they lied in the same branch of the phylogenetic tree. The corresponding homology of nucleotide sequence and amino acid sequence was 99.8% and 100%, respectively. The isolated Dengue virus type 2 belonged to genotype IV with Indonesia-76, Somalia-84 and Sri Lanka-90.
CONCLUSIONDengue virus was isolated from Shenzhen for the first time, and it was classified as type 2. It was confirmed that the type 2 Dengue virus may come from the epidemic area in Malaysia.
