Background: In Malaysia, the most common soiltransmitted helminth infections are A. lumbricoides, T. trichiura and hookworms. However, as there have been no extensive surveys on these infections, it is difficult to estimate with certainty the current overall incidence of infection with soil-transmitted helminths (STHs) among the Malaysian population including the Orang Aslis. Materials and Methods: A study was conducted to determine the infection rate of soil-transmitted helminths and intestinal protozoa among the Jehai Orang Aslis (Aborigines). The study was conducted between December 2005 and August 2006, in four Jehai villages of Perak State, Malaysia. A total of 175 stool samples was collected and personal identification such as name, age, household identification, and date of collection were recorded on the spot during collection. Faecal smears were stained with Trichrome for protozoa cysts and trophozoites and the modified Ziehl-Neelsen acid-fast method for the oocyst of Cryptosporidium and Isospora. Wet mounts with tincture of iodine of both stool samples (10% formalin and PVA) were also examined to detect cysts, ova and larva of intestinal helminths. Results: The prevalence rates of Trichuris trichiura, Ascaris lumbricoides and hookworm among the Jehai were 70.8%, 24.0%, and 10.9% respectively. The prevalence of Entamoeba coli, Entamoeba histolytica, Giardia intestinalis, Blastocystis hominis, and microsporidium was 40.6%, 33.7%, 25.7%, 91.4%, and 27.4% respectively. The difference in prevalence rates among the different age-groups and sex were found not significant. Children aged 0-9 years old had the highest prevalence rate of intestinal parasites and only 2 (1.1%) were free of any intestinal parasites. Conclusion: Intestinal parasitic infections were therefore still common among these people. Children aged 0-9 years old were found to have the highest infection rate of all the intestinal parasites examined. Further investigations are needed to determine more specific transmission of these infections, so that an attempt to control these infections can be made.

Objective To evaluate early skeletal muscle myopathy with contrast‐enhanced ultrasound ( CEUS) in diabetic rabbits . Methods Alloxan ( 100 mg/kg ) was given intravenously to 11 New Zealand w hite rabbits . Another 5 age‐matched normal rabbits were used as controls .CEUS was performed at baseline and 1 ,2 ,3 months after the establishment of diabetes ,respectively . T hen ,skeletal muscle samples were obtained for pathological observation . Additionally ,the diabetic rabbits were divided into 3 groups according to their pathologic findings : mild , moderate , and severe myopathy group . M icro‐perfusion parameters ,including artery‐to‐vein transit time ( A‐VT T ) ,muscle tissue mean transit time ( M‐M T T ) and muscle tissue peak intensity ( M‐PI) were calculated .

CEUS can quantify impaire muscle microcirculation ,and is a valuable tool for assessment of diabetic myopathy .

Objective To observe the effects of percutaneous coronary angioplasty and stent implantation in periopera-tive nursing intervention effect. Methods From January 2012 to January 2014 year in our hospital, 64 cases of percuta-neous transluminal coronary angioplasty and stent implantation were observed, according to different nursing patients were randomly divided into intervention group (n=33﹚ and the control group(n=32﹚,the control group adopted random symptomatic care, the intervention group focused on the implementation of perioperative nursing, included preopera-tive preparation,and psychological nursing,observation and nursing cooperation during the operation, postoperative complications and nursing, observation of life, patients,the SAS score, SDS score, the incidence and nursing satisfac-tion, complications were compared between the two groups before and after treatment. Results After treatment, two groups of SAS, SDS scores were significantly decreased than before treatment(P<0.05﹚, and the SAS, SDS scores of pa-tients in the intervention group were lower than control group (P<0.05﹚. After interventional,nursing satisfaction rate was 93.75% in the intervention group,nursing satisfaction rate was 71.88%,was significantly higher than the con-trol group (χ2=6.348,P<0.05﹚. After intervention, the incidence of complications of intervention group was 12.50%, the control group was 31.25%, the incidence of postoperative complications of the intervention group was significantly lower than the control group(P<0.05﹚. Conclusion Percutaneous coronary angioplasty and stent implantation of perioper-ative nursing intervention measures can improve nursing satisfaction, improve the patients' negative psychological shape body, reduce the incidence of complications, is conducive to the recovery of patients with the disease.

Objective To exploring the correlation between serum miR-195 and metabolic associated fatty liver disease(MAFLD)in type 2 diabetes mellitus(T2DM)patients.Methods A total of 79 patients with T2DM who were treated in the Endocrinology Department of Gansu Provincial People's Hospital were enrolled in this study from October 2022 to August 2023.They were divided into simple T2DM(n=37)and MAFLD group(MAFLD,n=42)according to whether they were complicated with MAFLD.Meanwhile,34 healthy individuals who underwent physical examinations were selected as the normal control(NC)group.Results Compared with the NC group,FPG,HbA1c and HOMA-IR increased,while HDL-C decreased in T2DM and MAFLD group(P<0.05).The TG and hs-CRP levels were higher in MAFLD group than in NC and T2DM group(P<0.05).The serum miR-195 expression decreased sequentially(P<0.05),while FAS increased sequentially in NC,T2DM,and MAFLD group(P<0.05).Spearman correlation analysis showed that miR-195 was negatively correlated with FPG,HOMA-IR,hs-CRP,and FAS(P<0.05).Multiple linear regression analysis showed that HOMA-IR and FAS were the influencing factors for serum miR-195.Conclusions Down-regulation of serum miR-195 expression in patients with T2DM combined with MAFLD may be by glucose and lipid metabolism,IR and inflammatory response.

Objective:To investigate the correlation between the level of thyrotropin receptor antibody(TRAb) and bone turnover markers(BTMs) in the patients with newly-diagnosed Graves′ disease(GD).Methods:The clinical data of GD patients who were newly-diagnosed in the First Affiliated Hospital of Zhengzhou University from October 2016 to June 2021 were collected, including free triiodothyronine(FT 3), free thyroxine(FT 4), thyroid stimulating hormone, thyroid related antibodies, N-terminal procollagen of type I collagen(PINP), N-terminal osteocalcin(N-MID), β-cross-linked C-telopeptide of type I(β-CTX), blood lipid and renal function, etc. Results:There were 618 GD patients with an average age of(43.7±13.2) years(male∶female=1∶1.99). The PINP and β-CTX level in male GD patients were significantly higher than those in female(all P<0.05). Spearman correlation analysis showed that PINP, N-MID and β-CTX were positively correlated with FT 3, FT 4, TRAb, serum calcium and serum phosphorus; and negatively correlated with body mass index and low density lipoprotein cholesterol(all P<0.05). Linear regression analysis showed that TRAb was positively correlated with lg-PINP, lg-N-MID and sqrt-β-CTX in the univariate model of total GD patients( β were 0.006, 0.005, and 0.006, respectively; all P<0.001); positive correlation remained after adjusting for thyroid function(all β=0.004, all P<0.001); and for multiple confounding factors(model 3 and 4, all P<0.05). Results of univariate and adjusted thyroid function models with GD in different genders were consistent with the total patients(all P<0.05). Conclusion:TRAb is a risk factor for accelerated bone turnover in GD patients which is independent of thyroid function.

Background: Long coronavirus disease 2019 (COVID-19) in recovered patients (RPs) is gradually recognized by more people. However, how long it will last and the underlining mechanism remains unclear. Methods: We conducted a prospective follow-up study to evaluate the long-term symptoms and clinical indices of RPs at one-year after discharge from Union Hospital, Wuhan, China between December 2020 to May 2021. We also performed the 16S rRNA sequencing of stool samples from RPs and healthy controls (HCs) and analyzed the correlation between the gut microbiota and long COVID-19. Results: In total, 187 RPs were enrolled, among them, 84 (44.9%) RPs reported long COVID-19 symptoms at one-year after discharge. The most common long-term symptoms were cardiopulmonary symptoms, including chest tightness after activity (39/187, 20.9%), palpitations on exercise (27/187, 14.4%), sputum (21/187, 11.2%), cough (15/187, 8.0%) and chest pain (13/187, 7.0%), followed by systemic symptoms including fatigue (34/187, 18.2%) and myalgia (20/187, 10.7%), and digestive symptoms including constipation (14/187, 7.5%), anorexia (13/187, 7.0%), and diarrhea (8/187, 4.3%). Sixty-six (35.9%) RPs presented either anxiety or depression (42/187 [22.8%] and 53/187 [28.8%] respectively), and the proportion of anxiety or depression in the long symptomatic group was significantly higher than that in the asymptomatic group (41/187 [50.6%] vs. 25/187 [24.3%]). Compared with the asymptomatic group, scores of all nine 36-Item Short Form General Health Survey domains were lower in the symptomatic group (all P < 0.05). One hundred thirty RPs and 32 HCs (non-severe acute respiratory syndrome coronavirus 2 infected subjects) performed fecal sample sequencing.Compared with HCs, symptomatic RPs had obvious gut microbiota dysbiosis including significantly reduced bacterial diversities and lower relative abundance of short-chain fatty acids (SCFAs)-producing salutary symbionts such as Eubacterium_hallii_group, Subdoligranulum, Ruminococcus, Dorea, Coprococcus, and Eubacterium_ventriosum_group. Meanwhile, the relative abundance of Eubacterium_hallii_group, Subdoligranulum, and Ruminococcus showed decreasing tendencies between HCs, the asymptomatic group, and the symptomatic group. Conclusion This study demonstrated the presence of long COVID-19 which correlates with gut microbiota dysbiosis in RPs at one-year after discharge, indicating gut microbiota may play an important role in long COVID-19.

Objective:To compare the spermatogenes response of human chorionic gonadotropin(HCG)combined with human menopausal gonadotropin(HMG)in patients with idiopathic hypogonadotropic hypogonadism(IHH)and congenital combined pituitary hormone deficiency(CCPHD), and to explore related factors.Methods:Clinical data of 90 IHH patients and 61 CCPHD patients from January, 2014 to November, 2018 were retrospectively analyzed. Spermatogenesis was compared between the two groups receiving combined gonadotropin therapy. The patients were then divided into two subgroups: spermatogenesis subgroup and nonspermatogenesis subgroup. Related factors of spermatogenesis after the combined gonadotropin therapy were investigated.Results:After the combined treatment of HCG/HMG for 3, 6, and 9 months, the patients with CCPHD revealed lower testicular sizes than those with IHH( P=0.004, 0.021 and 0.032, respectively). Compared with IHH patients, CCPHD patients had larger testicular volume increments( P<0.001), higher spermatogenesis rates( P=0.048), and shorter initial time for sperm appearance( P<0.001)after 24-month treatment. Multivariate logistic regression analysis showed that lower total cholesterol(TC)(IHH group: OR=5.508, 95% CI 1.110-27.326, P=0.037; CCPHD group: OR=4.068, 95% CI 1.077-15.371, P=0.039)was an independent risk factor of poorer spermatogenesis in patients with IHH and CCPHD. Conclusions:The patients with CCPHD demonstrate a better response to combined gonadotropin treatment than those with IHH. Lower TC is an independent risk factor for poor spermatogenesis of combined HCG/HMG therapy in patients with IHH or CCPHD.

Objective:To analyze the changes of fasting plasma glucose(FPG)level before and after menopause.Methods:Kailuan health checkup cohort was used to extract data of women aged≥18 years who participated in the first physical examination of Kailuan physical examination cohort and had menopausal age at the end of the seventh physical examination. A total of 3 749 women with 22 057 physical examination records were included in the analysis. Natural logarithmic transformation was applied to FPG, and a segmented linear mixed-effects model was used to analyze the changes in ln-transformed FPG before and after menopause. Additionally, an interaction analysis was performed to assess the multiplicative effect of baseline age and baseline body mass index(BMI)on ln-transformed FPG concerning pre- and post-menopausal periods.Results:The average age of the first physical examination for women in this study was (45.63±4.52)years, the median menopausal age was 51(50~53)years, and the median number of physical examinations was 6(5~7)times. The results of the piecewise linear mixed effect model showed that lnFPG increased from 1 year before menopause, with an average annual increase of 0.021 mmol/L, and continued to increase from menopause to 5 years after menopause, with an average annual increase of 0.007 mmol/L. LnFPG tended to be stable after 5 years of menopause. Baseline age could affect the changes of lnFPG before and after menopause, and there was a negative multiplicative interaction between baseline age ≥45 years and the time period from 6 years to 1 year before menopause( P=0.032). Women with baseline age ≥45 years had a higher average annual increase in lnFPG from 1 year before menopause to 5 years after menopause than women with baseline age <45 years( P<0.05). On lnFPG, there was a positive multiplicative interaction between baseline BMI and time segments around menopause. Compared to women with BMI <24.0 kg/m 2, obese women displayed more annual increase in lnFPG from 6 years to 1 year before menopause as well as from menopause to 5 years after menopause( P<0.05). Conclusions:Menopause has an adverse impact on FPG, with the most significant changes occurring within the period of one year before menopause and up to five years after menopause. Age and BMI significantly influence the changes in FPG before and after menopause.

Objective Through the detection of treponema pallida antibody in the unpaid blood donors in Wenzhou area,the recall self-test and recall test were carried out on the blood donors who were reactive to enzyme-linked immunosorbent assay(ELISA)test,and the feasibility of the recall plan was evaluated.Methods From January 2021 to May 2023,275 652 blood donors who successfully participated in unpaid blood donation were tested by anti-treponema pallidum(TP)ELISA,the reactivity rate and S/CO value of different reagents were compared,and the reactivity of single reagent was detected by ELISA.In addition,24 blood donors who volunteered to participate in the recall more than six months after the last blood donation screening were informed of the recall by way of interview,targeted health consultation,general examination and preliminary screening test were passed,and blood samples were collected for recall self-test and recall test.Results A total of 275 652 people were tested by anti-TP ELISA,and 627 cases were found to be reactive,with a reactivity rate of 0.23% ,including a double reagent reactivity rate of 0.12% and a single reagent reactivity rate of 0.11% .The ratio of S/CO≥5.00 with double reagent was 73.6% (240/326),and the ratio of S/CC＜5.00 with single reagent was 92.4% (278/301).24 people entered the recall process,20 people were successfully recalled,3 people failed to pass the self-test and 1 person failed to pass the test.The recall success rate was 83.3% (20/24).Conclusion The problem of false reactivity of anti-TP ELISA test single reagent in blood collection and supply institutions is prominent.Through the established recall scheme,the self-test and recall test of blood donors with strong recall intention can not only ensure the safety of blood donors,but also improve the construction of blood collection and supply service system.

Objective To understand the situations of departments of intensive care units (ICUs) of different level hospitals in Guizhou Province, and to provide directions and evidences for improving quality control in critical care medicine.Methods A county-level hospital and a provincial-level hospital's comprehensive ICU in Guizhou Province were selected to record and analyze and compare the structural indicators, patient admission and transfer, disease distribution, ventilator associated pneumonia (VAP), intravascular catheter related blood stream infection (CRBSI) and catheter-associated urinary tract infection (CAUTI) of the two hospitals' comprehensive ICU in 2017.Results The ICU of the People's Hospital of Suiyang County (county hospital) was found in 2012, and the ICU of the Affiliated Hospital of Guizhou Medical University (provincial hospital) was found in 1994. Until 2017, there were 10 and 46 beds, 6 (all of them hold bachelor's degree) and 18 physicians (6 of them hold PhD, 5 of them hold master's degree, 7 of them hold bachelor's degree), 17 (4 of them hold bachelor's degree, 13 of them hold college degree or graduated from secondary school) and 69 nurses (2 of them hold master's degree, 53 of them hold bachelor's degree, 14 of them hold college degree or graduated from secondary school) in the two ICUs respectively, there were significant differences in the education background of the physicians and nurses between the two ICUs (bothP < 0.01). During 2017, 471 cases were admitted to the ICU of the county hospital while 1633 cases were admitted to the ICU of the provincial hospital. Compared with the ICU of the provincial hospital, the ratio of the patients with acute physiology and chronic health evaluationⅡ(APACHE Ⅱ) ≥ 15 at admission was lower (74.8％ vs. 85.1％,P < 0.01), the ratio of direct admission was higher (30.8％ vs. 17.4％,P < 0.01), the ratio of the patients admitted to the ICU more than once was lower (0.8％ vs. 5.0％,P < 0.01), the ratio of the patients whose the length of ICU stay less than 24 hours was higher (51.6％ vs. 13.7％,P < 0.01), the ratio of the patients whose the length of ICU stay more than 28 days was lower (1.1％ vs. 2.9％, P < 0.05), the ratio of the patients discharged against-advice (25.5％ vs. 20.5％,P < 0.05) was higher, the ratio of the patients transferred to other hospitals was higher (5.1％ vs. 0.3％,P < 0.05), and the ICU mortality was lower (4.0％ vs. 13.9％,P < 0.01) in the ICU of the county hospital. The top three kinds of diseases treated in the ICU of the county hospital were brain injury (27.4％), trauma (19.1％) and toxication (6.8％); while in the ICU of the provincial hospital were brain injury (18.6％), sepsis (16.2％) and severe acute pancreatitis (4.8％). In addition, the incidences of VAP, CRBSI and CAUTI in the ICU of the county hospital were 10.0/1000 ventilator days, 1.4/1000 catheter days, 0.5/1000 catheter days; while in the ICU of the provincial hospital were 5.8/1000 ventilator days, 2.0/1000 catheter days, 3.7/1000 catheter days, respectively.Conclusions There are short of physicians and nurses in the ICU of the provincial and county hospitals in Guizhou Province, and the educational level of the medical staff in the ICU of the county hospital is relatively low. Moreover, there were significant differences in the admissions and treatments and the outcomes of the critically ill patients between the two ICUs. The characteristics of the ICUs of county hospitals should be fully considered when the quality control of critical care medicine and continuing medical education are done.
