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 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.

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.

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 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 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.

Resveratrol (3, 5, 4'-trihydroxy-trans-stilbene) was first identified from white hellebore (Veratrum grandiflorum) root and began to attract interest when its presence in red wine and cardiovascular activities were reported, leading to speculation of its contribution to the 'French paradox'. Besides the cardiovascular protection, potential health benefits of resveratrol include calorie restriction-like effects, cancer prevention and adjunctive therapy, and neuroprotection. In order to achieve translational applications of these potential benefits, pharmacokinetic research was performed for plasma pharmacokinetics and related disposition of orally dosed resveratrol. This paper summarizes the known human pharmacokinetic characteristics of resveratrol after oral administration and various attempts to improve its systemic exposure level from the perspectives of systemic exposure and in vivo process. However, available pharmacokinetic data of resveratrol has raised conundrums that limit translating potential benefits to clinics: (1) differences between the unchanged resveratrol used in bioactivity studies and its major circulating forms (i.e., metabolites) after dosing; (2) resveratrol's test concentrations used to exert in vitro bioactivities related to the benefits significantly higher than the compound's clinically achievable concentrations; (3) resveratrol's concentrations achievable (estimated from the pharmacokinetics) from doses used to produce in vivo efficacy significantly lower than the effective concentrations found in studies of related action mechanism (suggesting unreliability of test mechanism). In the last part of this review, we provide recommendations for future pharmacokinetic investigations of resveratrol, including a more systematic investigation of systemic exposure to resveratrol metabolites, their access to in vivo loci responsible for the benefits, and their disposition in target cells; an investigation of colon-luminal exposure to resveratrol and its metabolites for accessing colonic microbiota; and a multi-compound pharmacokinetic investigation of red wine.

ObjectiveWe examined the principal respiratory pathogens in patients with acute respiratory tract infection in Taizhou, Zhejiang Province during 2020‒2021 to provide evidence for prevention, diagnosis and treatment of acute respiratory tract infection. MethodsFrom September 2020 to August 2021, a total of 2 831 cases with acute respiratory tract infection were collected from two influenza sentinel surveillance hospitals in Taizhou, which had then received the examination of 22 respiratory pathogens by multiple fluorescence quantitative PCR. ResultsThe total positive rate of respiratory pathogens in 2 831 samples was 14.13%, among which enterovirus (7.77%) and respiratory syncytial virus (1.59%) were the principal pathogens. Except enterovirus, there was no significant difference in the positive rate of pathogens detected by gender(P>0.05). Moreover, there was significant difference in pathogens by age (P<0.05), with the highest positive rate in 0‒4 years(35.21%). There was also significant difference in pathogens by seasons (P<0.05), with the highest positive rate in summer(20.54%). ConclusionThe positive rate of acute respiratory tract infection decreases significantly, compared with that before the COVID-19 epidemic. The differences in the positive rate differ significantly by age and seasons. Comprehensive consideration of diverse factors before diagnosis and the utilization of multiple fluorescent quantitative PCR can quickly and effectively determine the pathogens in the early stage of infection. Our findings may provide certain support for the diagnosis and treatment of acute respiratory infections in the context of COVID-19 in Taizhou.
