To analyze all-cause mortality among hepatitis C cases aged ≥18 years in Yuxi City from 2005 to 2023 and explore the interactions of factors influencing survival time. Baseline and follow-up data for hepatitis C cases reported during this period were extracted from the Chinese National Notifiable Disease Reporting System. Survival time and related factors were assessed using the Cox proportional hazards model. Kaplan-Meier cumulative mortality risk curves were generated for treated and untreated hepatitis C cases, and interactions among subgroups of various influencing factors were examined. A total of 5 110 hepatitis C cases aged ≥18 years were reported from 2005 to 2023, encompassing 35 349.25 person-years of observation with the follow-up time duration M ( Q1, Q3) was 6.17 (2.33, 11.08) person-years. There were 763 all-cause deaths, corresponding to a mortality density of 2.16 per 100 person-years. Survival analysis showed a statistically significant difference in cumulative mortality between the treated and untreated groups (Log-rank χ2=122.033, P<0.001), with a lower risk of death observed among treated patients. Additive model analysis showed that there was a synergistic interaction between treatment status and age group, with relative excess of interaction, attributable proportions of interaction, and synergy index of 6.16 (95 %CI: 2.70-9.61), 1.83 (95 %CI: 1.46-2.30), and 0.42 (95 %CI: 0.31-0.53), respectively; and between treatment status and gender. There was a synergistic interaction between treatment status and sex, with relative excess of interaction, attributable proportions of interaction, and synergy index of 2.63 (95 %CI: 1.14-4.13), 1.56 (95 %CI: 1.19-2.06), and 0.32 (95 %CI: 0.17-0.46), respectively. The cause of death composition were 38.53% (249 cases) attributed to hepatitis C-related causes.The leading non-hepatitis C-related causes of death were cardiovascular and cerebrovascular diseases, pulmonary diseases, malignancies, drug overdose, and injuries. In conclusion, hepatitis C cases ≥18 years of age in Yuxi City had a lower cumulative mortality rate when treated than when untreated. Treatment status interacted with age and gender on patient survival, respectively. Changes in patients with concomitant cardiovascular diseases, pulmonary diseases and malignancies should be focused.

Objective Chorioamnionitis in pregnancies with preterm premature rupture of membranes(PPROM) may lead to perinatal morbidity. There is no definite diagnostic method for detecting chorioamnionitis before delivery. In this retrospective study, the diagnostic value of five inflammatory markers, including white blood cell (WBC), neutrophil percentage (NEU), c-reactive protein (CRP), interleukin-6 (IL-6), and procalcitonin (PCT) of subclinical chorioamnionitis in PPROM were investigated. Methods A total of 74 PPROM (Group A: 21 PPROM without infection; Group B: 43 PPROM with subclinical chorioamnionitis;Group C:10 PPROM with chorioamnionitis) and 46 controls (Group D:normal full-term pregnancies) were recruited from the Third Affiliated Hospital of Army Medical University between 2013 and 2017. The five markers were measured within 24 hours before the delivery. The diagnostic value of inflammatory markers for subclinical chorioamnionitis were assessed by t test and ROC curve. Results The levels of WBC, NEU and IL-6 in group A were significantly higher than those in group D (T=5.412, Z=-3.312, T=2.798, all P<0.05). The levels of five inflammatory markers in group B and C were all significantly increased compare with group D(Zb=-5.797, Zb=-5.296, Zb=-5.116, Zb=-3.279, Zb=-4.36, Tc=7.732, Zc=-4.622, Zc=-4.591, Zc=-3.509, Zc=-4.387,all P<0.05). Group B CRP, IL-6 and PCT levels were significantly higher than those of group A(Z=-3.10, Z=-2.95, Z=-2.202, all P<0.05). All five markers of group C were significantly higher than those of group A(T=-5.285, Z=-2.536, Z=-3.819, Z=-3.228, Z=-3.719, all P<0.05). The levels of WBC, NEU and IL-6 in group C were significantly higher than those in PPROM group B(Z=-3.296, T=-2.738, Z=-3.501, all P<0.05). In terms of predictive capability of subclinical chorioamnionitis, the individual area under ROC curve (AUC) of CRP, IL-6, and PCT were 0.740, 0.671, and 0.728 corresponding to the optimal cutoff 10.3 mg/L, 5.995 pg/ml, and 0.055 ng/ml respectively. The sensitivity value were 39.5％, 60.5％ and 74.4％, the specificity value were 100％, 85.7％and 61.9％.The area under the ROC curves of CRP+IL-6,CRP+PCT,IL-6+PCT and CRP+IL+6+PCT were 0.746, 0.805, 0.776 and 0.816. The sensitivity value were 51.2％, 74.4％, 81.4％ and 62.8％, the specificity value were 95.2％, 81％, 66.7％and 90.5％. Conclusions The model (combined with PCT, CRP and IL-6) may be helpful for the diagnosis of the subclinical chorioamnionitis in PPROM. Combined diagnosis of two markers in PCT,CRP and IL-6 could be superior to single inflammatory marker. Combined diagnosis of three could be better,which may provide a reference for clinical diagnosis.

Objective To establish the reference intervals of hemoglobin A 1c( HbA1c ) and fasting plasma glucose ( FPG ) in the first and second trimester of pregnancy in Chongqing , and to evaluate the viability of the combination of HbA 1c and FPG in screening gestational diabetes mellitus (GDM).Methods The study retrospectively selected the pregnant women seen at the Department of Obstetrics and Gynecology in Daping Hospital between September 2014 and August 2015.The results of FPG during 10-13 pregnant weeks and 75 g oral glucose tolerance test ( OGTT ) and HbA1c during 24-28 pregnant weeks were available.Totally 185 cases were assigned into GDM group , and 269 cases were assigned into normal group based on the American Diabetes Association ( ADA) guidelines.Reference intervals of HbA 1c and FPG in normal pregnant woman were developed .The difference of HbA 1c , FPG and OGTT results between two groups was analyzed.T-student test, NcMemar test,signed rank sum test, ROC curve were used for statistical analysis.Results The reference intervals of HbA 1c and FPG in first and second trimester were 4.58%-5.52%,4.21-5.49 mmol/L and 4.03-5.08 mmol/L.The FPG level in first and second trimester and HbA 1c level in GDM group vs normal group were(5.06 ±0.37) vs(4.85 ±0.32)mmol/L(t=6.569,P=0.000), 5.23(5.11,5.4) vs 4.74(4.54,4.91) mmol/L(z=-14.31,P=0.000)and 5.3(5.1,5.4)% vs 5.2(5.0, 5.3)%( z=-5.79,P=0.000) respectively.The area under receiver operating characteristic curve ( ROC) of HbA1c , and FPG in first and second trimester was 0.655, 0.659 and 0.890 respectively.When the cut-off value of HbA1c was 5.35%, the AUC of the combination of HbA 1c and FPG in second trimester was 0.898, the sensitivity was 0.838,and the specificity was 0.859.The kappa coefficient for identifying GDM between OGTT and the combined method was 0.692(P=0.000).Conclusion HbA1c combined with FPG is of some value in screening GDM.

Objective To investigate the gestation-specific reference intervals (GRIs) and dynamic changes of thyroid function at different gestational ages in Chongqing .Methods Combining self-sequential longtitudinal with cross-sectional study, the serum samples from 640 pregnant women with different gestational age were collected from June 2014 to September 2015 in the Third Military Medical University. The free triiodothyronine (FT3), free thyroxine (FT4), thyroglobulin (TG), thyroid-stimulating hormone (TSH), thyroid peroxidase antibody (TPOAb), and antithyroglobulin antibody (TGAb) were detected by the direct chemiluminescence method.According to China Guideline for the diagnosis and treatment of thyroid disease in pregnancy and postpartum in 2012, the reference interval of the thyroid function was calculated.The data were analyzed by Chi square test .Results Established GRIs of thyroid function during pregnancy in Chongqing:The GRIs was 3.68-5.59 pmol/L for FT3, 9.34-17.02 pmol /L for FT4, 0.18-5.26 mIU/L for TSH in 6-9+6 weeks of pregnancy; the GRIs was 3.69-6.03 pmol /L for FT3, 8.42-15.75 pmol/L for FT4、0.09-4.85 mIU/L for TSH in 10-13+6 weeks of pregnancy; the GRIs was 3.24-5.46 pmol /L for FT3, 6.50-14.24 pmol/L for FT4, 0.11-5.13 mIU/L for TSH in 14-27+6 weeks of pregnancy;the GRIs was 3.06-5.05 pmol /L for FT3, 6.12-11.69 pmol/L for FT4, 0.75-3.67 mIU/L for TSH in 30-34 weeks of pregnancy; the GRIs was 2.96-5.00 pmol/L for FT3, 6.26-11.36 pmol /L for FT4, 0.84-5.54 mIU/L for TSH in 36-40 weeks of pregnancy.Screening by GRIs, the prevalence of thyroid dysfunction was 8.75% (46), however, the prevalence was 37.07% (195) in according with the guidelines,χ2 =120.5,P =0.000.The overdiagnosis rate was 28.32%(149 /526).Using the guidelines of thyroid disease and our GRIs, the thyroid disease was found 116 (22.05%) and 30 (5.70%) in the first screening. Moreover, the thyroid disease was found 79(19.27%) and 10(3.23%) during the repeat screening in the normal population.Conclusions Using the GRIs for thyroid function tests in normal singleton pregnant women could reduce the risk of over diagnosis .The detection rate of repeat screening of TPOAb negative patients was close to the first screening detection rate , and repeated screening could reduce the risk of missed diagnosis for thyroid dysfunction in pregnancy women .(Chin J Lab Med, 2016, 39:511-515 )

Objective To investigate the effect of perioperative regional intra peritoneal chemotherapy on postoperative recurrence of advanced gastric cancer.Methods Eighty-six patients with advanced gastric cancer were divided into observation group (44 patients) and control group (42 patients) according to the aspiration of patients.All patients received 2-4 cycles of chemotherapy of PCF regimen before and after surgical treatment.Observation group was combined with perioperative regional intraperitoneal chemotherapy,and control group only received surgical treatment.The treatment effectiveness and the status of postoperative recurrence were compared between two groups.Results The response rate of control group and observation group were 76.2％ (34/42) and 93.2％ (41/44),respectively.There was significant difference (P ＜ 0.05).The adverse effect of the two groups were gastrointestinal adverse reaction and myelosuppression.There was no significant difference between two groups (P＞ 0.05).After followed up for 3-36 months,6 patients in observation group occurred recurrence,and 14 patients in control group occurred recurrence.The long-term recurrence rate (＞ 24 months) between two groups had significant difference (P ＜ 0.05).Conclusion Perioperative regional intraperitoneal chemotherapy has better effectiveness on inhibiting the postoperative recurrence of advanced gastric cancer.
