Objective To investigate the effects of visfatin gene overexpressian on insulin sensitivity and plasma fibroblast growth factor 21 (FGF-21) level in rats. Methods The recombinant visfatin plasmid was constructed and transfected into normal rats. The euglyeemic-hyperinsulinemie clamp experiments were performed to evaluate the change of insulin sensitivity before and after administration of the plasmid, and plasma FGF-21 level was determined by radioimmunoassay. Results Plasma visfatin levels and glucose infusion rates (GIR) were significantly increased [(1.49±0.06 vs 0.99±0.04) and (35.3±1.4 vs 27.6±1.7) mg·kg-1·min-1,respectively, all P<0.01]. Fasting insulin level was significantly decreased [(14.5±3.7 vs 24.4±6.2) mU/L,P<0.05], total cholesterol and high-density lipoprotein cholesterol were significantly decreased [(1.31±0.10 vs1.76±0.22) mmol/L and (0.59±0.04 vs 0.95±0.15) mmol/L, respectively, all P<0.05], and plasma FGF-21 level was also decreased [(2.25±0.19 vs 2.59±0.23)μg/L, P<0.05] after plasmid being injected 3 days compared with that before injection, but there were no significant differences in fasting glucose and adiponectin levels before and after administration. Conclusion The transfection of visfatin plasmid increases plasma visfatin level, decreases FGF-21 levels and improves insulin sensitivity in normal rats.

Objective:To investigate the inhibitory effect of CLC-2 chloride channel targeted blocking on fibrosis of human conjunctival fibroblasts (HConF).Methods:HConF were divided into blank control group, lipofectamine 2000 (Lipo2000) group, nonsense small interfering RNA (siRNA) group, and CLC-2 siRNA transfected group.The HConF were cultured in medium containing the corresponding transfection reagents according to grouping.No intervention was given to blank control group.The expression level of CLC-2 mRNA of HConF was detected by real-time fluorescence quantitative PCR; absorbance ( A) value indicating the proliferative ability of HConF was determined by CCK-8 kit; the apoptosis ratio of HConF was tested by flow cytometry; the migration ability of HConF was identified by cell scratch test and Transwell migration assay; the contraction rate of HConF was assayed by collagen contraction test; the expression levels of collagenⅠ, collagen Ⅲ, PI3K, Akt, p-PI3K and p-Akt proteins were measured by Western blot. Results:Significant differences were found in relative expression levels of CLC-2 mRNA and A value among four groups ( F=90.110, 198.680; both at P<0.001). The relative expression level of CLC-2 mRNA and A value were significantly lower in CLC-2 siRNA transfected group than nonsense siRNA group, showing statistically significant differences (both at P<0.001). The proportion of apoptotic HConF in blank control group, Lipo2000 group, nonsense siRNA group, and CLC-2 siRNA transfected group was (4.78±1.10)%, (4.54±1.51)%, (4.82±0.88)% and (28.90±0.91)%, respectively, and a statistically significant difference was found ( F=363.260, P<0.001). The proportion of apoptotic HConF was significantly higher in CLC-2 siRNA transfected group than nonsense siRNA group, with a statistically significant difference ( P<0.001). Statistically significant differences were found in cell migration rate and the number of migrating cells among four groups ( F=74.493, 1 625.431; both at P<0.01). The cell migration rate of HConF in CLC-2 siRNA transfected group was significantly lower and the number of migrating cells was significantly smaller than those of nonsense siRNA group, with statistically significant differences (both at P<0.001). A statistically significant difference in contraction rate was found among four groups ( F=104.692, P<0.001). The contraction rate of HConF was significantly lower in CLC-2 siRNA transfected group than nonsense siRNA group, and the difference was statistically significant ( P<0.001). Statistically significant differences were found in relative expression levels of collagen Ⅰ and collagen Ⅲ proteins, p-PI3K/PI3K ratio, and p-Akt/Akt ratio among four groups ( F=112.073, 456.931, 340.889, 43.021; all at P<0.001). The relative expression levels of collagen Ⅰ and collagen Ⅲ proteins, p-PI3K/PI3K ratio and p-Akt/Akt ratio in CLC-2 siRNA transfected group were significantly lower than those of nonsense siRNA group, showing statistically significant differences (all at P<0.05). Conclusions:Targeted blocking of CLC-2 chloride channel gene expression can inhibit fibrosis of HConF by promoting apoptosis of HConF through PI3K/Akt signaling pathway and inhibit fibrotic processes such as cell migration, collagen synthesis and collagen contraction.

PURPOSE: The evidence on effects of TV viewing time among premenopausal and postmenopausal women for breast cancer risk remains controversial and limited. MATERIALS AND METHODS: A prospective study encompassing 33,276 (17,568 premenopausal, and 15,708 postmenopausal) women aged 40-79 years in whom TV viewing time, menstrual, and reproductive histories were determined by a self-administered questionnaire. The follow-up was from 1988 to 2009 and hazard ratios (HRs) with 95% confidence intervals (CIs) of breast cancer incidence were calculated for longer TV viewing time in reference to shorter TV viewing time by Cox proportional hazard models. RESULTS: During 16.8-year median follow-up, we found positive associations between TV viewing time and breast cancer incidence with a borderline significant trend among total women and a significant trend among postmenopausal women. Among total women, the multivariable HRs (95% CIs) for risk of breast cancer in reference to < 1.5 hr/day of TV viewing time were 0.89 (0.59-1.34) for 1.5 to < 3.0 hr/day, 1.19 (0.82-1.74) for 3.0 to < 4.5 hr/day, and 1.45 (0.91-2.32) for ≥ 4.5 hr/day (p for trend=0.053) and among postmenopausal women, the corresponding risk estimates were 1.10 (0.42-2.88), 2.54 (1.11-5.80), and 2.37 (0.92-6.10) (p for trend=0.009), respectively. CONCLUSION: Prolonged TV viewing time was associated with increased risk of breast cancer, especially among postmenopausal women.

Objective:To analyze the distribution of clinically isolated fungal strains and their resistance to common antifungal drugs in Shandong province.Methods:Through the Shandong Children’s Bacterial & Fungal Drug Resistance Surveillance and Research Collaborative Network, a total of 1 030 fungi were collected in 46 hospitals of Shandong province from January 1 to December 31, 2018. The source and type of strains were analyzed, and antifungal drug sensitivity tests were performed by using the micro-dilution method. Whonet 5.6 and SPSS 22.0 were applied to analyze the data.Results:The overall main strains were Candida albicans (38.74%, 399/1 030), Candida tropicalis (16.99%, 175/1 030) and Candida parapsilosis (16.41%, 169/1 030); the main fungi strains in child patients were C. albicans (52.50%, 63/120), C. parapsilosis (12.50%, 15/120) and C. tropicalis (9.17%, 11/120); the main fungi strains in adult patients were C. albicans (36.37%, 331/910), C. tropicalis (17.03%, 155/910) and C. parapsilosis (15.27%, 139/910). The isolation rate of main Candida strains from January to March and August to December was much higher than that of other months. The drug resistance rates of C. albicans to fluconazole and voriconazole were 7.14% and 7.43%, respectively, and the drug resistance rates to itraconazole were 50.44%. The resistance rates of C. tropicalis to fluconazole, voriconazole and itraconazole were 29.05%, 23.29% and 48.65%, respectively. The sensitivity rates of C. parapsilosi to fluconazole, voriconazole and itraconazole were 93.06%, 93.75% and 94.44%, respectively. Candida glabrata showed a dose-dependent sensitivity rate of 2.33% to fluconazole. Analysis of 244 blood fungi strains showed that non-candida albicans bacteremia accounted for 70.08%. In the pathogen spectrum covering 92.22%, fluconazole was sensitive to 64.65% of the pathogens, voriconazole was 68.88%, and amphotericin B was 88.75%. After quantification, the effective rates of fluconazole, voriconazole and amphotericin B in the clinical treatment of fungal bacteremia were 70.10%, 74.69% and 96.23%, respectively. Among them, the sensitivity rate of voriconazole to C. tropicalis was lower than that of fluconazole. Conclusions:Candida is the main clinical fungus isolates in hospitals of Shandong province. The resistance rate of C. tropicalis to azole antifungal drugs is on the rise, and the sensitivity of other Candida species to clinically used antifungal drugs is basically stable.

Purpose:
Sedentary behavior attributes to the increased risk of some cancers and all-cause mortality. The evidence is limited for the association between television (TV) viewing time, a major sedentary behavior, and risk of colorectal cancer death. We aimed to examine this association in Japanese population.
Materials and Methods:
A prospective cohort study encompassed of 90,834 men and women aged 40-79 years with no prior history of colorectal cancer who completed a self-administered food frequency questionnaire, and provided their TV viewing information. The participants were followed-up from 1988-1990 to the end of 2009. The hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated by the Cox proportional hazard regression for risk of colorectal cancer mortality according to TV viewing time.
Results:
During the median 19.1-year follow-up period, we documented 749 (385 men and 364 women) colorectal cancer deaths. The multivariable-adjusted HRs for mortality from colorectal cancer were 1.11 (0.88-1.41) for 1.5 to < 3 hr/day, 1.14 (0.91-1.42) for 3 to < 4.5 hr/day and 1.33 (1.02-1.73) for ≥ 4.5 hr/day in comparison to < 1.5 hr/day TV watching; p-trend=0.038, and that for 1-hour increment in TV viewing time was 1.06 (1.01-1.11). Moreover, the multivariable-adjusted HR (95%CI) of colon cancer for 1-hour increment in TV viewing time was 1.07 (1.02-1.13). Age, body mass index, and level of leisure-physical activity did not show significant effect modifications on the observed associations.
Conclusion
TV viewing time is associated with the increased risk of colorectal cancer mortality among Japanese population, more specifically colon rather than rectal cancer.

Objective:To observe the therapeutic effect of intraocular lens (IOL) protected phacoemulsification (PHACO) in patients with hard nucleus cataract.Methods:A randomized controlled clinical study was conducted.A total of consecutive 120 patients (120 eyes) with hard nucleus cataract of Emery grade Ⅳ or Ⅴ were enrolled from January 2019 to May 2022.The patients were randomly divided into PHACO group receiving routine PHACO, IOL protected PHACO group receiving PHACO under IOL protection, and extracapsular cataract extraction (ECCE) group receiving ECCE, with 40 cases (40 eyes) in each group.Finally, 99 patients completed the follow-up, including 30 cases (30 eyes) in PHACO group, 35 cases (35 eyes) in IOL protected PHACO group, and 34 cases (34 eyes) in ECCE group.The total operation time, intraoperative PHACO time and cumulative energy release of each patient were recorded.The corneal endothelial cell density (ECD), coefficient of variation in endothelial cell area (CV), hexagonal endothelial cell ratio (6A), corneal astigmatism and the number of eyes with different grades of uncorrected visual acuity were measured and compared after 3-month follow-up.The intraoperative and postoperative complications were recorded.This study adhered to the Declaration of Helsinki and was approved by the Ethics Committee of Yanbian University Hospital (NO.2023002).Patients were informed of study content and purpose and signed a consent form before treatment.Results:There was no significant difference in ultrasonic energy and time between PHACO group and IOL protected PHACO group ( P=0.691, 0.982).The total operation time was (38.81±2.73) and (36.45±3.45) minutes in PHACO group and IOL protected PHACO group, significantly shorter than (69.60±4.35) minutes in ECCE group (both at P<0.001).There was no significant difference in age, sex, lens nucleus hardness and other baseline data among the three groups before operation (all at P>0.05).Three months after operation, the number of patients with higher uncorrected visual acuity in PHACO group and IOL protected PHACO group was larger than that in ECCE group ( P=0.006, 0.007).The ECD and 6A in IOL protected PHACO group were (2 155.57±177.88)/mm 2 and (41.31±5.18)%, respectively, which were significantly higher than (1 912.64±224.11)/mm 2 and (36.18±3.27)% in PHACO group, and the CV in IOL protected PHACO group was (50.34±5.90)%, which was lower than (55.67±3.30)% in PHACO group, showing statistically significant differences ( P=0.007, 0.003, 0.005).At 1 week and 3 months after the operation, the corneal astigmatism was significantly lower in IOL-protected PHACO group than in ECCE group, but higher than in PHACO group, and the difference were statistically significant (all at P<0.05). Conclusions:Compared with conventional PHACO, IOL-protected PHACO can effectively reduce the damage of corneal endothelium caused by ultrasonic energy, shorten the operation time and reduce postoperative inflammatory reaction compared with ECCE, and does not significantly increase postoperative corneal astigmatism.IOL-protected PHACO is an effective improved surgical method for patients with hard nucleus cataract.
