OBJECTIVE To explore the association between the use of oral progesterone drugs in early pregnancy and gestational diabetes mellitus （GDM）. METHODS Through real-world retrospective cohort research method， pregnant women who underwent the oral glucose tolerance test （OGTT） at the Affiliated Maternal and Child Health Hospital of Nantong University between January 2022 and January 2023 were enrolled. Based on whether oral progesterone drugs were used in early pregnancy， they were divided into treatment group and control group； propensity score matching （PSM） with a 1∶1 ratio was employed to control for confounding factors； Logistic regression and linear regression were employed to analyze the association between drug factors （whether use of oral progesterone drug， duration of medication， dosage， and drug type） and outcome indicators （occurrence of GDM， fasting blood glucose levels， and OGTT 1 and 2 h blood glucose levels in late pregnancy）. RESULTS A total of 709 pregnant women were enrolled in the two groups before PSM； after PSM， 256 cases were included in both the treatment group and the control group. The results of association analysis indicated that there was no significant association between the use of oral progesterone drugs and GDM （P＞0.05）； but a significant correlation was found with OGTT 1 h blood glucose levels [β＝0.965， 95%CI （0.007，1.922）， P＜0.05]， specifically with Dydrogesterone tablets [β＝0.977， 95%CI （0.009， 1.944）， P＜0.05] and Progesterone soft capsules [β ＝1.089， 95%CI （0.077， 2.102）， P＜0.05]. There was no significant correlation between other drug factors and outcome indicators （P＞0.05）. CONCLUSIONS The use of oral progestogen drugs in early pregnancy is not significantly associated with GDM. The blood glucose levels in late pregnancy， especially OGTT 1 h blood glucose levels， have a certain correlation with Progesterone soft capsules and Dydrogesterone tablets.

ObjectiveTo analyze the epidemiological characteristics of patients with hepatitis C in Jinhua City, Zhejiang Province from 2005 to 2023, so as to provide a scientific basis for the prevention and control of hepatitis C. MethodsThe data on patients with hepatitis C, as well as whose current address is in Jinhua City, from 2005 to 2023 were collected from the infectious disease surveillance system of the China Disease Control and Prevention Information Management System. Descriptive epidemiological methods were used to analyze the temporal, spatial and demographic distribution characteristics of hepatitis C. ResultsA total of 2 326 cases of hepatitis C were reported in Jinhua from 2005 to 2023, including 2 death cases, with an average annual incidence rate of 2.19/100 000, showing a trend which rose first and then declined and then rose again. Hepatitis C was reported all the year round without significant seasonal pattern. In terms of the number of reported cases and the average annual incidence rate, Yiwu City ranked the first place. From 2005 to 2023, a total of 1 438 (61.82%) male cases and 888 (38.18%) female cases were reported, and the reported incidence rate was higher for males (2.62/100 000) than that for females (1.74/100 000), showing a statistically significant difference (χ²=92.937, P<0.001). Most cases aged between 30 to <50 years old (1 175, 50.52%), and the incidence rate of hepatitis C among the age group of 40‒<50, 50‒<60, 60‒<70 years old was showing an upward trend, with farmers (1 024, 44.02%) as the main occupation . ConclusionThe prevalence of hepatitis C in Jinhua City is generally at a low level, with an incidence rate of increasing and then decreasing, but rise up again after 2019. Therefore, epidemic surveillance and health education among the male, middle-aged and elderly people and farmers, as well as the key regions where the migrant workers flows in should be enhanced.

Background Electroplating technology is widely used in the mechanical manufacturing industry. Electroplating workers may be exposed to occupational hazards such as chromium, zinc, cyanides, and sulfuric acid. With the continuous improvement of protective conditions, occupational hazards have been effectively controlled, but there is less focus on the potential acute occupational poisoning that may occur during the electroplating process. Objective To identify causes of an acute chromium poisoning accident occurred during the cleaning process of electroplating tank in a hardware processing plant, and to formulate relevant prevention and control measures to avoid similar poisoning accidents. Methods Occupational history, medical history, and treatment process of the poisoned worker were inquired in detail, his inpatient medical records were consulted , and his blood samples were tested. Occupational health investigation and testing were carried out at the scene of the poisoning accident. Results The air concentration of peak exposure (CPE) and permissible concentration-time weighted average (CTWA) of chromium and its compounds in the workplace were 0.49 mg·m⁻³ and 0.31 mg·m⁻³ respectively. The results of auxiliary test were Serum chromium 4175.85 μg·L⁻¹, serum creatinine 1370.2 μmol·L⁻¹, urea 42.28 mmol·L⁻¹, and urine osmotic pressure 248 mosm·L⁻¹. The final diagnosis was occupational acute severe toxic nephropathy (chromium and its compounds) and occupational chemical skin moderate burn (chromic acid, sulfuric acid). The prescribed treatment included right lower limb expansion skin grafting, hemodialysis and symptomatic support. The patient’s condition was stable and gradually improved after the treatment. Conclusion The main causes of the poisoning accident include weak awareness of the employer of occupational disease prevention and control; failures in fulfilling legal obligations of occupational disease prevention and control, implementing effective occupational disease prevention measures, and providing proper occupational health and safety training and effective personal protective equipment. In order to protect the health of workers, the relevant government departments and employers should attach great importance to the prevention and control of occupational diseases, such as strengthening training and education, increasing the intensity of occupational health supervision, and urging employers to implement occupational disease prevention measures in accordance with the law.

OBJECTIVE To discuss the participation of clinical pharmacists in rational drug use management by informatization clinical pathway under diagnosis related groups(DRGs) background by taking glycyrrhizic acid injection as an example. METHODS Based on the PDCA cycle theory, the evaluation scheme was established to find the problems in the use of glycyrrhizic acid injection in Jinhua Municipal Central Hospital, and the necessity of glycyrrhizic acid injection in the pathway was determined according to the needs of diagnosis and treatment, and the elimination and maintenance were carried out. The rational rate of drug use and the changes of monitoring indexes were compared before and after intervention in the same period(Q2 2021 vs Q2 2022). RESULTS Compared with the same period in 2021, the rational use rate of glycyrrhizic acid injection increased to a certain extent in the second quarter of 2022, and the utilization rate, the number of intravenous administration per capita per day, the intensity of use and the average drug cost per case all decreased. CONCLUSION Under the background of DRGs, the participation of clinical pharmacists in rational drug use by informatization clinical pathway can reduce the irrational use of glycyrrhizic acid injection and reduce the hospital monitoring index.

ObjectiveTo determine the antibody levels of varicella-zoster virus （VZV） in healthy individuals aged 1 to 30 years in Songjiang District of Shanghai， and to provide evidence for further development of varicella immunization strategies for healthy population. MethodsSix village committees were selected in Songjiang District through multi-stage stratified random sampling method from July to September 2022. Healthy individuals aged 1 to 30 years old in these villages were recruited and 3‒5 mL of venous blood was collected. Anti-VZV IgG antibody was tested by ELISA. Positive rate of anti-VZV IgG antibody and geometric mean concentration （GMC） were determined. ResultsA total of 315 healthy individuals aged （10.97±8.38） years were included in this study， of which 165 were males aged （11.00±8.52） years and 150 were females aged （10.96±8.25） years. Blood samples were collected and tested for anti-VZV IgG antibody， with the overall positive rate of 55.24% （174/315）. The GMC was calculated to be 99.73 mIU·mL^-1， with the GMC in those tested positive for anti-VZV IgG antibody of 413.11 mIU·mL^-1. The positive rate of anti-VZV IgG antibody and GMCs across age groups ranged between 13.33%‒86.67% and 16.36‒355.14 mIU·mL^-1， respectively. The highest GMC was found in the group of 20‒30 years old （355.14 mIU·mL^-1）， followed by 132.41 mIU·mL^-1 in the group of 5‒ years old and 138.12 mIU·mL^-1 in the group of 15‒ years old. Moreover， the positive rate was 38.47% in the group with 1-dose varicella vaccine and 63.49% in the group with 2 doses， while the GMC were 53.28 mIU·mL^-1 and 130.79 mIU·mL^-1 in these two groups， respectively. Multivariable analysis revealed that occupation was a risk factor associated with anti-VZV IgG antibody （OR=2.540）. Stratified analysis by varicella immunization history showed that among 2-dose vaccination group， time interval since the last dose was a protective factor （OR=0.315）. ConclusionsThe overall positive rate of anti-VZV IgG antibody in healthy population in Songjiang District of Shanghai remains low. The 2-dose varicella vaccination should be strengthened to improve the coverage in susceptible population.

Objective To investigate the correlation between heparin-binding protein(HBP)and vascular permeability in patients with sepsis.Methods Four hundred infected patients admitted to Affiliated Jinhua Hospital Zhejiang University School of Medicine from November 2019 to November 2022 were retrospectively selected and divided into sepsis group(n=190)and non-sepsis group(n=210)according to whether they were diagnosed with sepsis or not.HBP,the difference between hematocrit(HCT)and serum albumin(ALB)(HCT-ALB)and percentage of fluid overload were compared between two groups.Pearson method was used to analyze the correlation between HBP,HCT-ALB and percentage of liquid overload.Results HBP,HCT-ALB and percentages of fluid overload in sepsis group were significantly higher than those in non-sepsis group(P<0.05).Pearson correlation analysis showed that serum HBP level was positively correlated with HCT-ALB and percentage of fluid overload 24h after admission(P<0.05).Conclusion Increased vascular permeability in patients with sepsis may be related to the high level of HBP released by neutrophils stimulated by bacterial toxins.

Objective To evaluate the relationship between perioperative myocardial injury(PMI)and serum N/OFQ levels in elderly patients with coronary heart disease.Methods Totally 120 elderly patients who underwent hip fracture surgery under general anesthesia from January 2022 to May 2023 were included,including 60 patients with coronary heart disease(CHD group)and 60 patients without coronary heart disease(control group).The venous blood of patients was collected 10 minutes before anesthesia induction(T0),12 hours after surgery(T1)and 24 hours after surgery(T2)to detect the content of N/OFQ and high-sensitivity myocardial troponin I(hs-cTnI)in serum.Record perioperative adverse cardiovascular events(PACE)and the use of vasoactive drugs during surgery.Results Compared with the control group,the N/OFQ and hs cTnI levels at T0 and T1 in the CHD group were significantly increased(P<0.05).There was a positive correlation between N/OFQ and hs-cTnI levels at T1 and T2 in CHD and control group(P<0.05).The use of PACE and intraoperative vasoactive drugs in the CHD group was higher than that in the control group(P<0.05).Conclusion There is a correlation between the increased N/OFQ content and PMI in elderly patients with coronary heart disease after surgery,which may become an early predictive indicator of PMI.

ObjectiveTo understand the human immunodeficiency virus（HIV） infection status and related factors by using the HIV/AIDS sentinel surveillance data of men who have sex with men（MSM） in Jinhua City， Zhejiang Province. MethodsSnowball sampling method was used to recruit MSM receiving HIV sentinel surveillance from 2016 to 2021.The inclusion criteria were aged 18 years old and above， reported having anal sex with man in recent 6 months. Questionnaire-based interviews were conducted on a one-on-one basis. Data including the characteristics of demography and ethology were collected. Five milliliter of blood samples were taken after the questionnaire. HIV and syphilis was screened. The time trend was analyzed with χ² test. Multivariate logistic regression model was used to analyze the factors associated with HIV infection status among MSM. ResultsThe positive rate of HIV was 8.0% （127/1 597）， with an increasing trend （P=0.002）， but the linear correlation was weak（r=0.075）. The positive rate of syphilis was 5.2% （83/1 597）， with no significant difference （P=0.661）.The constituent ratios showed an increasing trend （P<0.05） in using condoms consistently， finding male sexual partners through Internet or dating software， having anal sex in the past week， using condoms every time during anal sex in the past 6 months， accepting prevention services of AIDS in the last year， and the overall awareness of AIDS related knowledge. Multivariate logistic regression analysis showed that who was from national minority （OR=2.27， 95%CI： 1.08‒4.73） and from other provinces （OR=1.68， 95%CI： 1.08‒2.62）， who failed to consistently use condoms every time during anal sex in the past six months （OR=3.03， 95%CI： 2.02‒4.54）， who never accepted prevention services of AIDS in the last year （OR=2.17，95%CI：1.44‒3.27）， who don’t know the knowledge of AIDS （OR=1.86， 95%CI： 1.12‒3.07）， and who was infected with syphilis （OR=2.35， 95%CI： 1.20‒4.61） were at higher risk for HIV infection among MSM. ConclusionThe positive rate of HIV remains at a certain level among MSM in Jinhua. High-risk groups such as the patients with syphilis infections and floating population from other provinces need to be paid close attention. It is suggested to further strengthen the promotion of the use of condoms， awareness of AIDS and syphilis， warning education and comprehensive intervention services.

Objective To establish evaluation of ozagrel sodium by weighted TOPSIS method so as to provide a reference for improving the rational use of ozagrel sodium.Methods Based on the drug instructions,guidelines,relevant literatures and Delphi method,the evaluation criteria for the clinical rationality of ozagrel sodium were formulated.Attribute hierarchical model(AHM)was used to assign weights to the indicators,the weighted TOPSIS method was employed to analyze and evaluate the rationality of 108 patients that discharged from the Third People's Hospital of Henan Province from January 2021 to April 2022.Results The reponse rates of two rounds of expert advice questionnaires were 100％,the authoritative coefficients(Cr)were 0.85,0.83(＞0.70),and the experts fully affirmed the items of the standard.Among the 108 cases evaluated,37 cases(34.26％)were judged to be reasonable,52 cases(48.15％)were judged to be basically reasonable and 19 cases(17.59％)were judged to be unreasonable.The main unreasonable problems were manifested in indications,the timing of administration,drug course and monitoring of efficacy and laboratory parameters.Conclusion The method of DUE of ozagrel sodium based on weighted TOPSIS is more comprehensively and intuitively.The application of ozagrel sodium in the hospital is relatively standardized,but there are problems in the course of medication,indications,and timing of administration.So it is necessary to promote the rational use by strengthening the cooperation between pharmacists and physicians,and improving pharmaceutical intervention.

Objective:To evaluate the reliability of a region-locked 3D-printed template combined with a bi-directional matching scheme in assistance of screw placement for thoracolumbar fractures.Methods:From January 2019 to March 2023, 52 patients with thoracolumbar fracture were treated at Department of Orthopedics, The People's Hospital of Liyang. They were 29 males and 23 females, with an age of (58.2±13.3) years. They were divided into a template group and a free-hand group according to the different screw placements. In the template group of 25 cases, a region-locked 3D-printed template combined with a bi-directional matching scheme was used to assist the pedicle positioning; in the free-hand group of 27 cases, the free hand screw placement was assisted only by image data and C-arm fluoroscopy. The operation time, intraoperative fluoroscopy frequency, intraoperative blood loss, complications, and placement accuracy were compared between the 2 groups. Visual analogue scale (VAS), Oswestry disability index (ODI), and anterior height ratio of the injured vertebra were compared between preoperation, 1 week postoperation, and the final follow-up, as well as between the 2 groups.Results:There were no statistically significant differences in the preoperative general data between the 2 groups, showing comparability ( P>0.05). All patients were followed up for (11.2±4.2) months. The differences were not statistically significant between the 2 groups in intraoperative blood loss, rate of complications, VAS or ODI at preoperation, 1 week postoperation, or the final follow-up, or in anterior height ratio of the injured vertebra ( P>0.05). In the template group, the operation time [(80.1±18.5) min] was significantly longer than that in the free-hand group [(69.4±16.6) min], the intraoperative fluoroscopy frequency [2 (2, 3) times] significantly lower than that in the free-hand group [3 (3, 4) times], and the placement accuracy [98.4% (127/129)] significantly higher than that in the free-hand group [91.8% (112/122)] (all P<0.05). All patients showed significant improvements in VAS, ODI and anterior height ratio of the injured vertebra at postoperative 1 week compared with the preoperative values, and the improvements at the last follow-up were significantly larger than those at postoperative 1 week ( P<0.05). No injury to the spinal cord, nerve root or blood vessel was observed postoperatively. Conclusions:In the treatment of thoracolumbar fractures, the screw placement assisted by a region-locked 3D-printed template combined with a bi-directional matching scheme is better than free-hand screw placement in terms of improved accuracy and reduced fluoroscopy, but the former incurs longer operative exposure than the latter. There is no significant difference between the 2 methods of screw placement in clinical efficacy.
