Objective:To explore the correlation between functional constipation （FC）and its related factors with acute appendicitis（AA）in children，so as to provide a reference for the prevention and clinical diagnosis and treatment of children with AA. Methods:A case-control study was conducted on 170 children diagnosed with AA in the Department of Pediatrics，the Second Affiliated Hospital of Air Force Military Medical University，from August 2022 to March 2023，and 170 non-AA children during the same period were selected as control objects.The clinical data，incidence of FC，symptoms related to FC，Bristol stool classification，past constipation history and other information were compared between two groups.Results:The incidence of FC in 170 children with AA was 22.9%（39/170），which was significantly higher than 10.6%（18/170）in the non-AA group（ P<0.01）；For children under four years old，the proportion of faecal retention in AA group was higher than that in non-AA group（25.6% vs. 9.3%, P<0.05）；For children ≥ 4 years old，the proportion of faecal retention and dyschezia in AA group were higher than those in non-AA group（28.2% vs. 6.9%，29.0% vs. 16.4%，respectively,all P<0.05）.The proportion of past constipation history in AA group was higher than that in non-AA group（29.4% vs.14.1%）.The duration of constipation in AA group was longer than that in non-AA group [0.00（0.00，1.25）month vs. 0.00（0.00，0.00）month,all P<0.01].The proportion of children with low Bristol stool classification in AA group was higher than that in non-AA group（ P<0.01）.Multivariate Logistic regression analysis showed that faecal retention[ OR=6.186（95% CI 2.336~16.380）] and long constipation time [ OR=1.310（95% CI 1.095~1.567）]were independent risk factors for AA in children（all P<0.05）. Conclusion:The incidence of faecal retention in children with AA is higher than that in children without AA，and the median duration of constipation is longer than that in children without AA.Fecal retention and long-term constipation are independent risk factors for AA in children.

Objective To monitor the antifungal resistance of clinical isolates of Candida spp.in the East China region.Methods MALDI-TOF MS or molecular methods were used to re-identify the strains collected from January 2018 to December 2022.Antifungal susceptibility testing was performed using the broth microdilution method.The susceptibility test results were interpreted according to the breakpoints of 2022 Clinical and Laboratory Standards Institute(CLSI)documents M27 M44s-Ed3 and M57s-Ed4.Results A total of 3 026 strains of Candida were collected,65.33％of which were isolated from sterile body sites,mainly from blood(38.86％)and pleural effusion/ascites(10.21％).The predominant species of Candida were Candida albicans(44.51％),followed by Candida parapsilosis complex(19.46％),Candida tropicalis(13.98％),Candida glabrata(10.34％),and other Candida species(0.79％).Candida albicans showed overall high susceptibility rates to the 10 antifungal drugs tested(the lowest rate being 93.62％).Only 2.97％of the strains showed dose-dependent susceptibility(SDD)to fluconazole.Candida parapsilosis complex had a SDD rate of 2.61％and a resistance rate of 9.42％to fluconazole,and susceptibility rates above 90％to other drugs.Candida glabrata had a SDD rate of 92.01％and a resistance rate of 7.99％to fluconazole,resistance rates of 32.27％and 48.24％to posaconazole and voriconazole non-wild-type strains(NWT),respectively,and susceptibility rates above 90％to other drugs.Candida tropicalis had resistance rates of 29.55％and 26.24％to fluconazole and voriconazole,respectively,resistance rates of 76.60％and 21.99％to posaconazole and echinocandins non-wild-type strains(NWT),and a resistance rate of 2.36％to echinocandins.Conclusions The prevalence and species distribution of Candida spp.in the East China region are consistent with previous domestic and international reports.Candida glabrata exhibits certain degree of resistance to fluconazole,while Candida tropicalis demonstrates higher resistance to triazole drugs.Additionally,echinocandins resistance has emerged in Candida albicans,Candida glabrata,Candida tropicalis,and Candida parapsilosis.

Medical and nursing staff should establish a comprehensive prevention and management mechanism based on influencing factors.

Objective To investigate the effect of different lower extremity force lines after initial total knee arthroplasty(TKA)on the early clinical outcomes of patients with varus knee osteoarthritis(KOA).Methods Fifty-five patients(73 knees)with KOA who underwent TKA at the First Affiliated Hospital of Xinxiang Medical University from October 2018 to March 2022 were selected as research subjects.According to the postoperative hip-knee-ankle angle(HKA),the patients were divided into the valgus alignment group(HKA＜-3°,4 knees),neutral alignment group(-3°≤HKA ≤3°,32 knees),mild varus alignment group(3°＜HKA＜6°,30 knees),and severe varus alignment group(HKA ≥6°,7 knees).The mechanical lateral distal femoral angle(mLDFA),mechanical medial proximal tibial angle(mMPTA),range of motion(ROM)of knees,and joint line convergence angle(JLCA)of the four groups of patients were measured before and 1 week after surgery.The Hospital for Special Surgery Knee Scores(HSS),The Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC)scores,and numeric rating scale(NRS)scores of the knee joints of patients in the four groups were also recorded preoperatively and 6 months postoperatively.Results The overall postoperative mLDFA,mMPTA,ROM and HSS scores were significantly greater than the preoperative values and the JLCA,WOMAC and NRS scores were significantly less than the preoperative values in 55 patients(73 knees)(P＜0.01).There was no statistically significant difference in the preoperative mLDFA,mMPTA,JLCA and ROM among the patients in the four groups(F=2.689,0.692,0.476,0.892;P＞0.05).Postoperative mLDFA,mMPTA,and ROM were significantly greater than preoperative values and JLCA was significantly less than preoperative value in patients in the neutral alignment,mild varus alignment,and severe varus groups(P＜0.05).Postoperative mMPTA and ROM were significantly greater than preoperative values and JLCA was significantly less than preoperative value in patients in the valgus group(P＜0.05);the difference was not statistically significant when compared with preoperative and postoperative mLDFA in patients in the valgus group(P＞0.05).There was no statistically significant difference in the postoperative JLCA and ROM among the four groups(F=1.164,1.045;P＞0.05).The difference in postoperative mLDFA and mMPTA was statistically significant among the four groups(F=21.068,4.551;P＜0.05);the mLDFA of patients in the neutral alignment,mild varus alignment,and severe varus alignment groups was significantly greater than that of the valgus alignment group,and patients in the mild varus alignment and severe varus alignment groups had greater mLDFA than those in the neutral alignment group,patients in the severe varus alignment group had greater mLDFA than those in the mild varus alignment group(P＜0.05);the mMPTA of patients in the neutral alignment,mild varus alignment,and severe varus alignment groups was less than that of patients in the valgus alignment group(P＜0.05);there was no statistically significant difference in the mMPTA among patients in the neutral alignment,mild varus alignment and severe varus alignment groups(P＞0.05).There was no statistically significant difference in the preoperative HSS,WOMAC and NRS scores among the four groups(F/x2=0.141,1.587,3.811;P＞0.05).Postoperative HSS scores were significantly higher and WOMAC and NRS scores were significantly lower than preoperative scores in all groups(P＜0.05).The difference between the postoperative HSS and WOMAC scores of patients in the four groups was statistically significant(F=6.216,7.632;P＜0.05).The postoperative HSS scores of patients in the neutral alignment group and the mild varus alignment group were significantly higher than those of the valgus alignment group and the severe varus alignment group(P＜0.05);the difference in the postoperative HSS scores of patients in the neutral alignment group compared with those of patients in the mild varus alignment group was not statistically significant(P＞0.05);and the difference in the postoperative HSS scores of patients in the valgus alignment group compared with those of patients in the severe varus alignment group was not statistically significant(P＞0.05).The postoperative WOMAC scores of patients in the valgus alignment,mild varus alignment and severe varus alignment groups were significantly higher than those in the neutral alignment group,and the postoperative WOMAC scores of patients in the valgus alignment and severe varus alignment groups were significantly higher than those of patients in the mild varus alignment group(P＜0.05);the difference in postoperative WOMAC scores of patients in the valgus alignment group compared with those in the severe varus alignment group was not statistically significant(P＞0.05).There was no statistically significant difference in the postoperative NRS scores among the four groups(P＞0.05).Conclusion The lower extremity force line in a neutral position after TKA has the best early clinical outcome for patients with preoperative varus KOA,and the lower extremity force line should be reconstructed to a neutral level during TKA.

Objective:To investigate the current situation of the fatalism of the disabled elderly in hospital, and to analyze the influencing factors, so as to provide a basis for the later development of targeted intervention programs.Methods:This was a cross-sectional survey study. From December 2 to 29, 2023, the convenience sampling method was used to investigate the disabled elderly hospitalized in 7 tertiary general hospitals in Sichuan Province by the general information questionnaire, the Activity of Daily Living scale and the Fatalism Scale. And its influencing factors were conducted by the multivariate linear regression.Results:A total of 280 questionnaires were distributed in this survey, and 269 questionnaires were effectively recovered, with an effective recovery rate of 96.07%(269/280). There were 136 males and 133 females, aged 60-69 years old with 61 cases, 70-79 years old with 103 cases, ≥80 years old with 105 cases. The score of the fatalism in hospitalized disabled elderly was (48.87 ± 10.02) points, of which the pre-determined dimension score was (18.73 ± 4.17) points, the luck dimension score was (12.75 ± 3.42) points, and the pessimistic dimension score was (17.39 ± 4.72) points. Multivariate linear regression showed that the frequency of visits to relatives and friends and the level of education were protective factors for the occurrence of fatalism (t=-3.02, -2.81, both P<0.05), and economic pressure was a risk factor for the occurrence of fatalism (t=4.35, P<0.01).Conclusions:The fatalistic view of the disabled elderly in the hospital is at a medium level.Medical staff can start from the influencing factors, formulate relevant intervention measures, and improve the level of the patient's fatalism.

OBJECTIVE To study the correlation between SLCO1B1 （521T＞C and 388A＞G） gene polymorphisms and the efficacy and safety of rosuvastatin. METHODS Retrieved from PubMed， Embase， Cochrane Library， PharmGKB， CNKI database and Wanfang database， the studies about the effects of 521T＞C and 388A＞G gene polymorphisms on the efficacy and safety of rosuvastatin were collected during the inception to Dec. 2023. The included data were analyzed by using RevMan 5.3 software. RESULTS A total of 16 studies were included. The results of meta-analysis showed that 521T＞C gene polymorphism was significantly correlated with the efficacy of rosuvastatin. In the dominant gene model， compared with TT genotype， CC+TC genotype significantly improved the efficacy of rosuvastatin in raising high-density lipoprotein cholesterol （HDL-C） [MD＝2.38， 95%CI（0.61，4.16）， P＝0.009 0]. In the homozygous gene model， compared with TT genotype， CC genotype significantly improved the efficacy of rosuvastatin in reducing total cholesterol [MD＝－7.50，95%CI（－13.05， －1.95）， P＝0.008 0]. In heterozygous gene model， compared with TT genotype， TC genotype significantly improved rosuvastatin in reducing low-density lipoprotein cholesterol （LDL-C） [MD＝－5.14， 95%CI（－9.74， －0.53）， P＝0.03] and increasing HDL-C [MD＝5.67， 95%CI 232102311200） （2.61， 8.73）， P＝0.000 3]. 388A＞G gene polymorphism was also significantly correlated with the efficacy of rosuvastatin. In dominant or homozygous gene models， compared with AA E-mail：dushuzhang911@163.com genotype， GG+AG genotype [MD＝－6.88， 95%CI （－7.46，－6.30），P＜0.000 1] or GG genotype [MD＝－9.23， 95%CI（－9.41， 9.04）， P＜0.000 1] significantly improved the efficacy of rosuvastatin in lowering LDL-C. In the heterozygous gene model， compared with AA genotype， AG genotype significantly improved the efficacy of rosuvastatin in lowering LDL-C [MD＝－3.00， 95%CI（－3.19， －2.82）， P＜0.000 1]， total cholesterol [MD＝－5.80， 95%CI（－6.00， －5.59）， P＜0.000 1] and triglyceride [MD＝－11.79， 95%CI（－19.57， －4.02）， P＝0.003 0]. In the recessive gene model， compared with AA+AG genotype， GG genotype significantly improved the therapeutic efficacy of rosuvastatin in reducing LDL-C[MD＝－4.31， 95%CI（－8.47， －0.14）， P＝0.040 0] and elevating HDL-C [MD＝4.49， 95%CI （2.20， 6.77）， P＝0.000 1]. Under 4 gene models， there was a significant correlation between 521T＞C gene polymorphism and rosuvastatin-related ADR probability （P＜0.05）， but no significant correlation was found in 388A＞G gene polymorphism （P＞0.05）. CONCLUSIONS The polymorphism of 521T＞C gene is significantly related to the efficacy and safety of rosuvastatin in lowering lipid， and the C allele may be one of the factors leading to the increase of rosuvastatin in lipid-lowering efficacy and ADR. 388A＞ G gene polymorphism is significantly associated with the lipid-lowering efficacy of rosuvastatin， but not with its safety.

OBJECTIVE To understand the polypharmacy burden and influencing factors of elderly tuberculosis （TB） in Guizhou province， and to provide reference for reducing the polypharmacy burden of patients. METHODS From April to July 2022， 405 elderly TB outpatients were selected from three designated TB hospitals in Guiyang City， Bijie City， and Qiandongnan Miao and Dong Autonomous Prefecture of Guizhou Province by convenience sampling method as investigation objects. The general situation questionnaire and the Living with Medicines Questionnaire （LMQ） were used for face-to-face survey. Descriptive analysis， one-way ANOVA and multivariate linear regression analysis were used to understand the score of polypharmacy burden of elderly TB patients and explore the factors effecting polypharmacy burden in TB patients. RESULTS The total polypharmacy burden score of 405 elderly TB patients was （112.65±14.59） points， which was higher than the threshold （110 points） for high burden standard in LMQ. Multivariate linear regression analysis showed that aged 80 to 92 years， self-financed+medical insurance， retreatment， drug resistance， and adverse drug reactions were the risk factors for polypharmacy burden in elderly TB patients （P＜0.05）； living in the city， family member management， volunteer management and intelligent tool-assisted management were the protective factors （P＜0.05）. CONCLUSIONS The burden of polypharmacy in elderly TB patients from Guizhou province is heavy， and is influenced by patient’s age， residence， payment method， treatment classification， drug resistance， adverse drug reactions， and medication management. It is recommended that medical staff should provide key populations with medication guidance based on influential factor for polypharmacy burden so as to reduce their polypharmacy burden.

OBJECTIVE To investigate the clinical efficacy and safety of rituximab （RTX） followed by belimumab （BLM） in patients with severe systemic lupus erythematosus（SSLE）. METHODS Nine SSLE patients， who were treated with RTX followed by BLM for more than 6 months in the Department of Rheumatology and Immunology of the First Affiliated Hospital of Zhengzhou University from October 2020 to June 2021， were enrolled. Baseline clinical data of patients， laboratory examination results and basic treatment status at weeks 0， 4， 12， and 24 of medication were collected retrospectively. The patients’ systemic lupus erythematosus disease activity index （SLEDAI） score， glucocorticoid dosage and serological indicators （complement C3， complement C4， serum albumin， and 24-hour urine protein quantification） level were analyzed. At the same time， the occurrence of adverse drug reaction was collected. RESULTS All 9 patients completed more than 24 weeks of RTX followed by BLM therapy. All patients suffered from renal impairment， of which 7 （77.8%） had renal pathology support， 3（33.3%） had blood system damage and 2 （22.2%） had nervous system damage. During treatment， with the prolongation of treatment time， the SLEDAI score， 24- hour urinary protein quantification， and glucocorticoid dosage of patients showed a significant downward trend， and ultimately decreased to the normal index level （P＜0.05）； serum albumin， complement C3 and complement C4 all showed a significant upward trend， eventually rose to the normal index level （P＜0.05）. During treatment and follow-up， 1 patient developed herpes zoster， 1 patient developed upper respiratory tract virus infection， and 1 patient developed urinary system bacterial infection. All patients recovered after symptomatic treatment. CONCLUSIONS In sequential use of RTX followed by BLM for SSLE， early administration of RTX can quickly stabilizethe condition， significantly alleviate clinical symptoms， and gradually normalize specific serological indicators； subsequent administration of BLM can reduce the type and dosage of basic treatment drugs； there is no increase in the incidence of adverse drug reactions.

Objective To study the effect and potential mechanism of Chaihuang Yishen Granules on renal fibrosis in mice with chronic kidney disease.Methods Thirty-six C57BL/6 male mice were randomly divided into sham group,model group,low-,and high-dose Chaihuang Yishen Granules groups(3.835 g·kg-1 and 7.67 g·kg-1),positive control group and Mincle ligand trehalose-6,6-dibehenate(TDB 10 mg·kg-1)group.Unilateral ureteral obstruction(UUO)was used to establish the model of renal fibrosis in mice.One hour after operation,mice in each drug-treated group were given corresponding drugs by gavage,and sham operation group and model group were given saline by gavage,once a day for 7 consecutive days.The pathological changes and fibrosis in the kidneys of mice in all groups were observed by hematoxylin eosin staining and Sirius red staining.The expressions and secretions of inflammatory factor IL-1β,IL-6 and TNF-α in kidneys of all groups were detected by Real-time PCR and ELISA.Immunohistochemistry and Western Blot were used to detect fibrosis indicators,including α-SMA and Fn protein levels.Immunofluorescence and Western Blot were further used to determine protein levels of Mincle and its downstream signal Syk/NF-κB.The proportion of Mincle positive macrophages was analyzed by flow cytometry.Results Compared with the model group,low-and high-dose Chaihuang Yishen Granules can effectively improve UUO-induced renal injury and fibrosis,and inhibit α-SMA and Fn protein levels in the kidney(P＜0.01).Moreover,high-dose Chaihuang Yishen Granules can effectively reduce the expressions and secretions of inflammatory factor IL-1β,IL-6 and TNF-α of kidney in UUO model(P＜0.01),as well as inhibit phosphorylation of NF-κB(P＜0.01).The mechanism study showed that Chaihuang Yishen Granules could significantly reduce the protein level of Mincle and the activity of its downstream signal Syk in the kidney of UUO mice(P＜0.01).After TDB was used to activate Mincle,the effect of Chaihuang Yishen Granules on improving renal injury,inflammatory factor secretion and fibrosis was significantly reduced(P＜0.05,P＜0.01).Conclusion Chaihuang Yishen Granules can improve UUO-induced renal injury,inflammation and fibrosis,and its mechanism may be related to the down-regulation of Mincle/Syk/NF-κB signaling pathway.

OBJECTIVE To provid e reference and sugge stions for improving the volume-based procurement of drugs and medical consumables （hereinafter referred to as “consumables”）in China. METHODS The relevant policy documents of centralized volume-based procurement of drugs and consumables published from November 2018 to November 2021 were retrieved ； the implementation status and problems of centralized volume-based procurement of drugs and consumables in China were analyzed by using the policy analysis method and referring to relevant research literatures. RESULTS & CONCLUSIONS National health department and healthcare security administration guaranted the rational use of selected products in medical institutions through incentive and supervision measures ；healthcare security administration should optimize the way of medical insurance payment ， promote the medical institutions to control the fees by themselves ，and conduct the credit evaluation of bidding and procurement ； medical products administration should evaluate the consistency of drugs and supervise the quality of selected products. With the normalization of centralized volume-based procurement of drugs and consumables organized by the state and trans-regional alliance ， the drug varieties and dosage forms included in centralized procurement were increasingly in line with the demand of Chinese pharmaceutical market. The price of most selected drugs decreased by more than 50％，and the decrease of consumables was significantly higher than that of drugs. The selected enterprises were mainly domestic generic drug enterprises ，and domestic consumables had gradually become the competitors and substitute of imported consumables. However ，there were still some problems such as repeated bidding and procurement in various alliances and provinces （autonomous regions and municipalities ）， unclear construction of compensation mechanism in medical institutions ，inconsistent bidding and procurement rules and quality evaluation standards for consumables ，low localization rate of some consumables ，low innovation level and profitability of pharmaceutical enterprises and consumables manufacturers. Local centralized volume-based procurement should be encouraged ，and the bidding and procurement rules and quality evaluation standards of “one product ，one policy ”should be gradually established. Great importance should be paid to the construction of compensation mechanism of medical institutions ，standardize zhangqiuyu739632@126.com the dynamic adjustment of medical serv ice prices ；pharma- ceutical enterprises and consumables manufacturers should increase research and development investment to transform into innovative and diversified enterprises ，so as to improve the competitiveness of domestic drugs and consumables.
