This restrospective case included 40 patients(79eyes)who underwent implantable collamer lens or toric implantable collamer lens implacement. Uncorrected and corrected distance visual acuities, refractions, posterior chamber intraocular lens vault,intraocular pressure,endothelial cell loss,cylinder axis of the toric intraocular lens were evaluated for moderate to high myopia and astigmatism. 2 years or above after operation mean uncorrected and corrected distance visual acuities were 0.830±0.269 and 0.980±0.241 respectively. The mean spherical equiva-lent was ( -0.66±1.08) D postoperatively. 29 eyes had implanted toric intraocular lens, which 24 eyes were un-der 15 degrees of the intended axis, 1 eye was under 30 degrees of the intended axis and 4 eyes were above 30 de-grees of the intended axis. The mean intraocular pressure was(1.76±0.41)kPa. The endothelial cell density loss was 11.18%. The mean vaults at 6 months and 2 years or above were (0.510±0.141)mm and (0.442±0.117) mm respectively. A statistically significant difference was found ( P <0.05 ) . Two sets of data were in the normal range. Phakic posterior chamber intraocular lens implantation appears safe and effective,which provides long-term predictable,stable refractive results.

Objective To analyze the clinical characteristics of chronic intestinal pseudoobstruction (CIPO).Methods Clinical data of 43 patients with CIPO admitted in Peking Union Medical College Hospital from January 2012 to December 2016 were retrospectively reviewed.The clinical manifestations,laboratory examinations,images,treatment and prognosis of CIPO patients were analyzed.Results There were 14 males and 29 females with an mean age of (41.9 ± 16.1) years.Among 43 patients,32 were admitted in Gastroenterology Department,6 in General Medicine Department and 5 in Rheumatology Department.Twenty two cases were primary CIPO and 21 cases were secondary.The main clinical manifestations were abdominal distension (93.0％),abdominal pain (67.4％),vomiting (67.4％),diarrhea (46.5％) and constipation (41.9％).All 43 patients had decreased body weight and body mass index (BMI);23.3％ (10/43) patients were complicated with anxiety and depression.53.5％ (23/43) patients presented anemia and 55.8％ (24/43) patients presented hypoalbuminemia.All patients with CIPO underwent abdominal X-ray,which showed intestinal obstruction;but there was no evidence of mechanical obstruction.The average length of hospital stay was (28.4 ± 13.9) d.Twenty three cases underwent gastric decompression;28 cases (65.1％) received parenteral nutrition,and 21 cases (48.8％) received enteral nutrition;and 9 abdominal operations were performed in 8 patients.Conclusion When clinical symptoms of intestinal obstruction appear without mechanical cause,CIPO should be considered and secondary factors should be screened.Unnecessary surgery should be avoided in CIPO patients.

Objective: To compare the efifcacy and safety of circumferential pulmonary vein antecourt isolation (CPVAI) ablation and stepwise linear (SL) ablation in treating the patients with atrial ifbrillation (AF) Methods: A total of 136 AF patients with catheter ablation under EnSite 3000 guidance in our hospital were retrospectively summarized. The patients included 93 paroxysmal AF and 43 persistent AF and divided into 4 groups. Paroxysmal AF with CPVAI ablation,n=45, Paroxysmal AF with SL ablation,n=48 and persistent AF with CPVAI ablation, n=18, persistent AF with SL ablation,n=25. The differences of left atrium diameter, ablation time, X-ray exposure time, the success rate and complication were compared among different groups. Results: For 12 months follow-up study, the success rate and complication were similar between 2 ablation methods for treating both Paroxysmal AF and persistent AF patients. For Paroxysmal AF patients, both ablation methods could effectively reduce left atrium diameter,P<0.01. The SL ablation had less procedural time than CPVAI ablation,P<0.01, while the X-ray exposure time was similar between 2 ablation methods. Conclusion: Both CPVAI and SL ablation methods were effective and safe for treating AF patients.

AIM: To discuss the effects of phytoestrogenic-genistein on cathepsin K (CK) expression stimulated by interleukin-1α (IL-1α) in osteoclast-like cells (OCLs) . METHODS: The OCLs were isolated from tissue of human giant cell tumor of bone (GCT) . The cells treated with reagents were divided into 7 groups including control (treated with phenol red-free-DMEM), vehicle (treated with 1.2 nmol· L-1 IL- 1α), 10-10-10-6genistein, genistein+ ICI 182.780, and 17[β-estrodiol (17β-E2) group. The cells were treated with 1.2 nmol· L-1IL-1α after pre-treated with genistein or 17β-E2 for 48 h (excluded the control group) . Expression of CK wasdetermined by reverse transcriptase-polymerase chain reaction (RT-PCR) and Western blot in OCLs stimulated by IL-1α in the presence of genistein or 17[β-E2. RESULTS: The obvious increase of expression of CK by IL1α in vehicle group was noted in comparing with control group (P ＜ 0.01 ) . Genistein down-regulated CK gene expression stimulated by IL-1α at the transcription level in a dose-dependent manner (r = 0.68, P ＜ 0.01 ) .Genistein down-regulated CK protein expression stimulated by IL-1α also in a dose-dependent manner (r = 0.61,P ＜ 0.01 ). The effects of genistein were abrogated partly after treatment with the estrogen receptor antagonist ICI 182.780. CONCLUSION: Genistein inhibits CK expression stimulated by IL-1α partly through estrogen receptor in OCLs.

OBJECTIVE: To observe whether curcumin could inhibit the accumulation of the collagen IV and fibronectin in the glomeruli in nephrotoxi sera nephritis rats. METHODS: Seventy-two healthy male Sprague-Dawley rats were divided into three groups, with 24 animals in each group. For normal control group, normal saline (0.5 ml/d) was injected through intra-caudal-vein for two days, and at the same time normal saline (0.5 ml/kg) was also daily administered intraperitoneally. For nephrotoxic sera nephritis group, nephrotoxic sera (0.5 ml/d) was injected through the tail vein for two days and dimethyl sulfoxide (0.5 ml/kg) was given intraperitoneally daily. For curcumin group, nephrotoxic sera was injected as above and meanwhile curcumin (50 mg.kg(-1).d(-1)) was administered intraperitoneally every day. Six rats in each group were killed on the 3rd, 7th, 14th and 28th day. Their renal tissue was fixed in 10% formalin for examining the expression of collagen IV and fibronectin. RESULTS: Minimal staining of collagen IV and fibronectin was detected in the basement membrane of normal control rats glomeruli. In the nephrotoxic sera nephritis rats and curcumin treated nephrotoxic sera nephritis rats, the accumulation of collagen IV and fibronectin was increased progressively, with significant difference in the accumulation of collagen IV (P<0.01) between these two groups at the same time points, while the significant difference in fibronectin accumulation (P<0.05) appeared only after the 7th days. CONCLUSION: Curcumin can reduce the accumulation of collagen IV and fibronectin in the glomeruli. Hence we postulated that curcumin might have beneficial effect for retarding glomerulosclerosis.

Objective: To analyze the relationship between daily behavior and self-perceived academic performance among students in Jiangxi, and to provide a scientific basis for developing health behavior among adolescents and children. Methods: By using stratified cluster sampling, 12 primary and secondary schools from six counties of Jiangxi Province were selected, and a total of 2 284 students were investigated with questions including breakfast consumption, number of days participating in sports activities (≥45 min) and the average screen time during the past 7 days. Regression analysis was carried out by using ordered multi-classification logistic. Results: Of the 2 284 students surveyed, 1 374(60.16%) perceived their academic performance as very good or good, 613 (26.84%) and 297(13.00%) perceived as moderate or poor. Primary school, having breakfast every day, not playing on mobile or computer during weekday was positively associated with higher self-perceived academic performance (OR=0.50, 0.57 and 0.64, respectively, P<0.05), no sports activities ≥45 min during the past 7 d was associated with poor(OR=1.57, P<0.01). Among the 2 284 students, 67.43% students ate breakfast every day in the past 7 d, 75.39% students did not play mobile phones or computers at school, 40.89% students did not participate in sports activities (≥45 min). Conclusion Breakfast skipping and insufficient physical exercise shows adverse effects, and no/limited screen time during weekdays shows positive effects on academic performance. Intervention of visky behaviors should to carried out from different perspectives to promote the develpment of the health habits among students.

Objective Observation of the anti-inflammatory and detumescence effects on experimental rheumatoid arthritis(RA)rabbits by moxibustion,With lentiviral vector mediated NLRP3 overexpression in RA animal models,to investigate the effect of moxibustion on anti-CCP/RF levels in synovial fluid of RA rabbit joints and its regulation mechanism of NLRP3.Methods Randomly divided thirty Japanese big-ear white rabbits into 5 groups:group of blank,group of model,group of moxibustion,NLRP3 overexpression group and NLRP3 overexpression negative group,with 6 rabbits in each group.Both joint of the model group,and the groups with moxibustion was injected into FCA(0.5 mL·kg-1),the blank group used the same method to inject sterile saline.On the 3rd day and the 10th day after treatment,10 μL of NLRP3 overexpression lentiviral vector was injected into the joint cavity of the NLRP3 overexpression group of rabbits.The rabbits in the NLRP3 overexpression negative group were injected with the same amount of LvGFP as Contrast.moxibustion bilateral"BL23","ST 36"of the groups with moxibustion(5 cones with one point in a day.6 days for 1 course,1 day for rest,3 courses of treatment in total.)After treatment,observe the circumference of each rabbit's left and right knee joints,the content of RF,anti-CCP,IL-18 in synovial fluid was detected by ELISA.Results Compared with the blank group,the left and right knee joint circumferences in the model group increased,and the anti-CCP,RF,and IL-18 contents in the synovial fluid of the knee joint increased significantly(P<0.01);compared with the modle group,The circumference of the knee joint decreased,and the content of anti-CCP,RF and IL-18 decreased significantly(P<0.01);compared with the moxibustion group,the circumference of the left and right knee joints in the NLRP3 overexpression group increased(P<0.05),the content of anti-CCP,RF and IL-18 increased(P<0.05).Conclusions Moxibustion has anti-inflammatory effects on experimental RA rabbits.Moxibustion at Shenshu(BL23)and Zusanli(ST36)can significantly reduce the level of anti-CCP,RF the immune effector,also IL-18,the in synovial fluid of RA rabbits knee joint,yet this effect can be declined significantly under NLRP3 overexpression,suggesting that moxibustion performed its anti-inflammatory regulation by suppressing abnormal immune function in experimental RA rabbits,which may be closely related to the NLRP3 expression.
