Objective To understand the utilization of immunization program vaccines in Liaoning Province and evaluate the vaccine management mode, and to provide a scientific basis for optimizing immunization strategies. Methods The vaccine collection data and vaccine administration data of vaccination units (including obstetric clinics) in the province from 2021 to 2024 were collected, and the vaccine utilization rate of immunization program was calculated. SPSS 13.0 software was used for data analysis, and χ² test was used for comparison. A two-sided P value of <0.05 was considered statistically significant. Results (1) From 2021 to 2024, vaccination units and obstetric clinics received a total of 15 993 884 doses of immunization program vaccines, with a total utilization rate of 79.34%. The highest utilization rate was the single-dose vaccine MPSV-AC (94.02%), followed by JE-L (91.92%). The lowest rate of use was the 5-dose strength vaccine MPSV-A (48.12%), followed by the 4-dose strength vaccine DT (63.13%). (2) Comparing MPSV-A and DT in different years, the utilization rate of MPSV-A and DT was the highest in 2021, 59.53% and 67.71%, respectively. From 2021 to 2024, the utilization rate of MPSV-A had a decreasing trend year by year, with the lowest being 38.65% (2024), and the loss coefficient of MPSV-A in each year was higher than that of DT. (3) Comparison of vaccine utilization rates in immunization programs around 2020, the utilization rate of single-dose vaccines increased significantly compared with before, while the utilization rate of multi-dose vaccines decreased compared with before 2020. Conclusion After 2020, the vaccine utilization rate of the immunization program in Liaoning Province has increased significantly, and the optimized vaccine management strategies has achieved remarkable results. Multi-dose vaccines remain highly susceptible to formulation-related factors and vaccination density. It is recommended to formulate precise vaccination strategies to reduce the loss of multi-dose vaccines.

[Purpose]To analyze cancer incidence and mortality in Xinjiang cancer registration ar-eas in 2020 and the trends from 2016 to 2020.[Methods]Incidence and mortality data of cancer reported by four cancer registration areas in Xinjiang in 2020 were collected.Crude incidence and mortality rates,age-standardized incidence and mortality rates by Chinese standard population(ASIRC/ASMRC),and world standard population(ASIRW,ASMRW),and cumulative rate(0～74 years old)were calculated.The Chinese standard population(2000 national census)and Segi's world standard population were used for standardization.Joinpoint regression was applied to ana-lyze the trends of incidence and mortality from 2016 to 2020,and the average annual percentage change(AAPC)was calculated.[Results]In 2020,the crude incidence rate of cancer in Xinjiang cancer registration areas was 291.67/105(286.64/105 for male,296.64/105 for female),ASIRC and ASIRW were 190.43/105 and 206.58/105,and the cumulative incidence rate(0～74 years old)was 20.51％.The crude mortality rate was 185.58/105(2 1 8.79/105 for male,152.78/105 for female),ASMRC and ASMRW were 109.13/105 and 126.64/105,and the cumulative mortality rate(0～74 years old)was 11.54％.In 2020,the incidence and mortality rates increased with age,peaking in the age groups of 80～84 and ≥85 years old,respectively.Lung cancer was the leading cause of incidence(crude incidence rate:51.13/10s),followed by female breast cancer,thyroid cancer,colorectal cancer and stomach cancer.Lung cancer was also the leading cause of mortality(crude mortality rate:41.14/105),followed by liver cancer,colorectal cancer,stomach cancer and fe-male breast cancer.There was no significant change in the ASIRC/ASMRC from 2016 to 2020(incidence AAPC=2.95％,mortality AAPC=8.51％,both P＞0.05).[Conclusion]The incidence and mortality of cancer in Xinjiang cancer registration areas were stable from 2016 to 2020.Lung cancer,digestive system cancers(colorectal,gastric,liver cancers),and female breast cancer re-main the main cancers threatening the health of Xinjiang residents,indicating the need to strengthen screening and early diagnosis and treatment.

Objective:To compare the differences in clinical characteristics among the patients at clinical high risk for bipolar disorder(CHR-BD),the patients with bipolar disorder(BD),and the healthy controls(HC)at low risk,and to provide the basis for the diognasis and treatment of CHR-BD.Methods:For the first time,the BD risk criteria and prospective structured assessment tools were jointly used in outpatients aged 16-30 years,and 43 CHR-BD patients were included to ensure the accuracy of the assessment.Meanwhile,33 BD patients and 32 HC subjects were also enrolled.The clinical symptoms,neurocognitive function,and global functional levels of the subjects in the three groups were evaluated using observer-rated and self-rated tools.The CHR-BD and BD groups were combined,and Logistic regression analysis was used to identify the independent influencing factors related to diagnostic status;Pearson or Spearman correlation analysis was used to analyze the correlations between the global functional levels and the symptoms or neurocognitive characteristics of the patients in CHR-BD and BD groups.Results:There were statistically significant differences in the scores of symptom and global functional level scales among HC,CHR-BD,and BD groups(P<0.05).Compared with HC group,the scores of mood symptoms(anxiety,depression,and mania/hypomania),psychotic symptoms,total affective temperament questionnaire scores,and some dimensions(cyclothymic,depressive,irritable,and anxious temperaments)in CHR-BD and BD groups were significantly increased(P<0.001),while the global functional levels were significantly decreased(P<0.001).Compared with BD group,the lowest global functional level score in the past year in CHR-BD group was significantly increased(P=0.022),while the current global functional level score was significantly decreased(P=0.005).No significant differences were observed in neurocognitive function scores among the three groups(P>0.05).The lowest global functional level score in the past year was an independent influencing factor for BD diagnosis[odds ratio(OR)=0.952,95%confidence interval(CI):0.917-0.988,P=0.010].In both CHR-BD and BD patients,the current global functional levels were negatively correlated with depressive(r=-0.417,P=0.005;r=-0.617,P<0.001)and anxiety symptoms(r=-0.360,P=0.018;r=-0.506,P=0.003).In BD patients,the current global functional level was negatively correlated with lifetime manic/hypomanic symptoms(r=-0.360,P=0.039),psychotic symptoms(r=-0.502,P=0.003),and affective temperament scores(r=-0.479,P=0.005),while the lowest global functional level in the past year was negatively correlated with lifetime manic/hypomanic symptoms(r=-0.391,P=0.024).Conclusion:CHR-BD patients share similar mood symptom characteristics with BD patients,and their global functional levels are negatively correlated with depressive and anxiety symptoms.BD patients exhibit worse lowest global functional levels in the past year,and their global functional levels are negatively correlated with manic/hypomanic symptoms.

This report described one patient of giant polycystic liver and polycystic kidney involving iliac fossa. Preoperative computed tomography (CT) revealed a large polycystic kidney occupying partially iliac fossa space. A decompression of lower pole of original kidney was planned for placing transplanted kidney. During total liver resection plus orthotopic liver transplantation, right polycystic kidney could move up on its own and iliac fossa space was released for placing transplanted kidney smoothly. Polycystic kidney shrunk markedly post-operation. It provided references for surgical planning of combined liver-kidney transplantation for this type of disease.

Objective:To analyze the prognosis and risk factors for complete common peroneal nerve injury after total hip arthroplasty (THA) and revision via the modified Hardinge approach.Methods:A retrospective study was conducted to analyze the clinical data of 11 patients (nerve injury group) who had developed complete common peroneal nerve injury after THA and revision via the modified Hardinge approach at Department of Joint Surgery, The Affiliated Hospital of Qingdao University from April 2016 to April 2022. There were 7 males and 4 females, with an age at the time of surgery of (59.5±10.1) years and a body mass index of (26.1±3.5) kg/m 2. In a 1∶5 ratio, another 55 patients were included in the nerve injury free group who had not developed common peroneal nerve injury after THA or revision and were matched in surgical year, surgical type, surgical approach, prosthesis fixation mode, and chief surgeon. The clinical data were compared between the 2 groups. Variables with P<0.05 were included in a multifactorial logistic regression model to analyze the risk factors for the complete common peroneal nerve injury after THA and revision via the modified Hardinge approach. The time for recovery of nerve function and functional recovery of the common peroneal nerve at the last follow-up were recorded in the nerve injury group. Results:The differences were statistically significant between the 2 groups in the comparisons of drainage tube placement, body mass index, operative time, and postoperative limb lengthening ( P<0.05). The multifactorial logistic regression analysis showed that absence of drainage tube placement ( OR=0.047, 95% CI: 0.003 to 0.680, P=0.025) and long operative time ( OR=1.063, 95% CI: 1.002 to 1.128, P=0.044) were the risk factors for complete common peroneal nerve injury after THA and revision. The 11 patients were followed up for (48.0±22.0) months after operation. The function of the common peroneal nerve recovered fully at postoperative 3, 21, and 24 months respectively in 3 patients, and began to recover at postoperative 2, 3, 10, and 48 months and recovered to muscle strength levels 3, 2, 2, and 1 at the last follow-up in 4 patients respectively. The neurological function of the common peroneal nerve did not recover in 4 patients whose feet drooped significantly during walking to seriously affect their daily life. Conclusions:Absence of drainage tube placement and long operative time are the risk factors for complete common peroneal nerve injury after THA and revision via the modified Hardinge approach. Once complete common peroneal nerve injury occurs, the prognosis is generally poor for the patients.

Objective:To investigate the clinical effect of intraarticular vancomycin on early periprosthetic joint infection (PJI) in knee arthroplasty and the incidence of postoperative complications.Methods:This is a retrospective cohort study. The clinical data of 1 867 patients who underwent primary knee arthroplasty at Department of Joint Surgery, the Affiliated Hospital of Qingdao University from April 2022 to June 2023 were retrospectively analysed, including total knee arthroplasty (TKA), robotic-assisted total knee arthroplasty (RA-TKA) and unicondylar knee arthroplasty (UKA). There were 687 males and 1 180 females, aged (68.0±11.2)years(range:45 to 87 years). Patients were divided into the vancomycin group and the control group according to whether or not intra-articular injection of 1 g of vancomycin powder dissolved in 30 ml of saline was performed after intraoperative joint capsule closure. In the vancomycin group, 925 patients were included, including 782 TKA, 27 RA-TKA and 116 UKA.In the control group, 942 patients were included, including 767 TKA, 99 RA-TKA and 76 UKA. Early PJI, wound complications, and vancomycin-related toxicity including acute renal collapse, ototoxicity, and allergic reactions were assessed within 3 months postoperatively. The data were compared using the independent sample t test, χ2 test, and Fisher's exact probability method, as appropriate. Major Extremity Trauma Research Consortium (METRC). Results:No PJI was found in all patients in the vancomycin group.Five cases (0.7%,5/767) of early PJI were found in TKA patients in the control group, with a statistically significant difference ( P=0.030); 1 case of early PJI was found in each RA-TKA and UKA patients, with non-significant difference compared with vancomycin group (all P>0.05). Two cases (0.3%,2/782) of incisional complications were found in TKA patients in the vancomycin group, and 4 cases (0.5%, 4/767) of incisional complications were found in TKA patients in the control group, with non-significant difference( P=0.449); no incisional complication was found in RA-TKA patients in the vancomycin group, and 1 case (1.0%,1/99) of incisional complications were found in RA-TKA patients in the control group, the difference was not statistically significant ( P>0.05); no incisional complication was found in both groups of UKA patients.No vancomycin-related acute kidney injury, ototoxicity, or allergic reactions was observed in all patients. Conclusion:Intra-articular injection of 1 g of vancomycin suspension after arthrotomy closure during TKA maybe lower the risk of early PJI without increasing the risk of wound complication and vancomycin-associated systemic toxicity.

Objective: To study the relationship between sugar sweetened beverages consumption characteristics and insomnia of college students in Yunnan Province, so as to provide evidence for sleep quality improvement of college students. Methods: A cluster random sampling method was used to select 2 515 college students from two universities (Kunming University and Dali Nursing Vocational College) in Kunming and Dali in Yunnan Province for a longitudinal study, including baseline survey (T1, November 2021) and three follow up surveys (T2: June 2022, T3: November 2022, T4: June 2023). Sugar sweetened beverages consumption of college students was collected by Semi quantitative Food Frequency Questionnaire and insomnia was assessed by Insomnia Severity Index Scale. Sugarsweetened beverages consumption was analyzed by Kruskal-Wallis test. The Mann-Whiter U test and Kruskal-Wallis test were used to compare the detection rate of insomnia in college students with different population characteristics, and the generalized estimating equations model was established to analyze the association between sugar sweetened beverages consumption and insomnia. Results: The reported rate of insomnia among college students from T1 to T4 was 21.2%, 23.6%, 30.5 % and 36.0%, respectively. The median of sugar sweetened beverages consumption per week was 5 (1,9) bottles per person, and there were significant differences in sugar sweetened beverages (carbonated beverages, fruit beverages, tea beverages, milk beverages, energy beverages) consumption among college students with different insomnia status ( χ 2=42.91, 23.67, 29.98, 61.70, 30.82, P <0.01). The analysis of the generalized estimating equation model revealed that the consumption of carbonated beverages ( β= 0.04, 95%CI =0.00-0.08) and the consumption of milk beverages among college students ( β=0.04, 95%CI =0.00-0.09) were correlated with insomnia ( P <0.05). The stratified analysis indicated that consumption of carbonated beverages by female college students was associated with insomnia [ β(95%CI )=0.06(0.01-0.11)]; consumption of milk beverages among college students from middle income family was associated with insomnia [ β (95% CI )=0.05(0.00-0.10)], and consumption of carbonated beverages and fruit beverages from college students with high household economic status were both associated with insomnia [ β (95% CI )=0.35(0.23-0.46), 0.12(0.00-0.24)] ( P <0.05). Conclusion Sugar sweetened beverages, especially carbonated beverages, are associated with insomnia among college students in Yunnan Province.

OBJECTIVE To explore the effect mechanism of Eucommia ulmoides on improving postpartum depression in rats. METHODS Pregnant rats were randomly divided into normal group， postpartum depression group， and low-dose and high-dose groups of E. ulmoides （1.34， 2.68 g/kg， calculated by crude drug）， with 10 rats in each group. Except for the normal group， the rats in other groups suffered from fear stress to induce postpartum depression model during pregnancy； at the same time of modeling， the administration groups were given relevant medicine intragastrically， while the normal group and postpartum depression group were given physiological saline intragastrically for 21 days. Postpartum behaviors of rats during the experiment were assessed using the open field test， Morris water maze test and sucrose preference test. Additionally， the levels of corticosterone （CORT） in serum， corticotropin releasing factor （CRF） and urocortin （UCN） in hypothalamus， and adrenocorticotropic hormone （ACTH） in hypophysis were detected； meanwhile， the protein expressions of CRF receptor 1 （CRFR1）， CRFR2， and voltage-dependent anion channel 1 （VDAC1） in hippocampal tissue were measured； the proportions of apoptotic cells and JC-1 high potential cells in hippocampal tissue were determined， and the morphology of hippocampal tissue was observed. RESULTS Compared with postpartum depression group， the high-dose group of E. ulmoides showed improvements in appetite， mental state， and hair color in rats； their body weight had increased； the scores of vertical movement， horizontal movement and self-sorting significantly increased； from the 2ed to 4th day avoidance latency significantly shortened， and the times of crossing the platform and the time of crossing the platform Δ 基金项目国家自然科学基金青年基金项目（No.82204789） significantly increased/prolonged （P＜0.05）； the ratio of glucose and water consumption significantly increased at 20 days of pregnancy and 30 days postpartum （P＜0.05）； the levels of CRF， UCN， ACTH and CORT， phagocytic rate， protein expressions of CRFR2 and VDAC1， and the proportion of apoptosis cells in hippocampal tissue were decreased significantly （P＜0.05）； the proportion of JC-1 high potential cells significantly increased （P＜0.05）， and the phenomenon of edema around neuronal cells was significantly improved. CONCLUSIONS E. ulmoides can improve postpartum depression by inhibiting excessive activation of hypothalamic-pituitary-adrenal axis， decreasing the expression of CRFR2， thereby inhibiting the expression of VDAC1， and decreasing the apoptosis of neuronal cells.
