ABSTRACT

Objective@#To evaluate health risks of five heavy metals in drinking water of rural schools in Henan Province, so as to provide scientific basis for drinking water safety in rural schools.@*Methods@#Totally 1 269 drinking water samples were collected and analyzed for five heavy metals (As, Cd, Cr 6+ , Pb, Hg) concentration in 106 cities and counties of Henan Province, and its spatial distribution characteristics were explored by geographic information system (GIS). Risk assessment method recommended by the United States Environmental Protection Agency (U.S. EPA) was applied to evaluate health risks from five heavy metals through oral ingestion.@*Results@#The qualified rate of As concentration was 100%, and the qualified rates of Cd, Cr 6+ , Pb and Hg were 99.9% , 99.9%, 99.5%, 99.6%. The highest carcinogenic risk was As (3.05×10 -5 ), followed by Cr 6+ (2.73×10 -5 ), and the highest non carcinogenic risk was As (0.158 3), followed by Pb(0.041 7). The carcinogenic risk and non carcinogenic risk were all higher in girls than boys. The carcinogenic and non carcinogenic risks were differences in different regions( P <0.05).@*Conclusion@#Health risks of five heavy metals in drinking water for rural schools in Henan Province were within the acceptable risk level recommended by EPA. As, Cr 6+ and Pb were the main health risk factors in drinking water, and that might impact negatively the healthy growth of primary and middle school students. These should be future efforts of drinking water safety management.

ABSTRACT

Objective@#To investigate the status of physical development, vitamin A and vitamin D among primary and middle school students in poor rural areas in Hubei, to evaluate the implementation effectiveness of the Nutrition Improvement Program for Rural Compulsory Education Students (abbreviated to the program) from 2012 to 2021.@*Methods@#In Enshi City, a pilot monitoring county of the program in Hubei, and a total of 2 554 students from one primary school and one junior middle school were randomly selected. During September to October in 2012-2021, height was measured, and fasting venous blood was collected from students, and serum vitamin A and vitamin D were detected.@*Results@#From 2012 to 2021, height, serum vitamin A and serum vitamin D concentration increased by 2.7 cm, 96.7 μg/L and 8.6 ng/mL. Growth retardation rate decreased by 1.0%. The subclinical and clinical deficiency of serum vitamin A decreased by 37.3% and 6.2%. The subclinical and clinical deficiency of serum vitamin D decreased by 45.7% and 8.5%. Height was positively correlated with serum vitamin A status and negatively correlated with serum vitamin D status ( r =0.08,-0.08, P <0.01).@*Conclusion@#The pilot counties of the program in Enshi, has witnessed improvement in height, serum vitamin A and vitamin D status among primary and secondary students. However, future efforts remains essential as subclinical deficiency of vitamin A and vitamin D are noted in some students. Serum vitamin A is positively associated with height, and vitamin D is negatively associated with height.Considering the correlation between serum vitamin A and vitamin D status with height, continued efforts should be implemented in poor rural areasto strengthen targeted nutrition intervention for students in Hubei.

ABSTRACT

Objective:To explore the intervention effect of humanistic management on anxiety and depression tendency of visiting physicians.Methods:The visiting physicians who began to further study in Beijing Anzhen Hospital, Capital Medical University from January 2016 to December 2018 were selected for humanistic management, and the visiting physicians from April 2013 to December 2015 were set as reference to conduct a questionnaire survey before and after the refresher training with the Hospital Anxiety and Depression Scale. Therefore, the visiting doctors all had the conventional refresher study management mode. On this basis, the intervention group established an individualized refresher study schedule, equipped the doctors with tutors, regularly visited the doctors and organized symposiums for them, assisted them to join the academic groups of the department, organized and coordinated the doctors to participate in the multi-disciplinary academic ward rounds, conducted negative emotional relief through the Balint groups, and integrated the cultural life of the refresher doctors into the cultural construction of the hospital and follow up the refresher doctors after the refresher training. SPSS 16.0 was used to perform t-test and variance analysis. Results:There was no difference in anxiety and depression scores between the two groups according to gender, type of refresher department, level of source hospital and length of study ( P > 0.05). Compared with the two evaluations in the intervention group, the second scores of anxiety for men and women [(5.90±1.37) vs . (6.48±1.87), (5.92±1.45) vs . (6.73±2.12)], doctors in each department [(5.50±1.23) vs . (6.76±2.35), (6.03±1.36) vs . (6.64±1.75), (5.98±1.50) vs . (6.64±2.15)], doctors from secondary and tertiary hospitals [(5.85±1.29) vs . (6.64±2.02), (6.00±1.50) vs . (6.78± 2.14)], the total score of doctors [(5.92±1.37) vs . (6.64±2.15), (5.92±1.47) vs . (6.68±1.98)] and the total score [(5.92±1.42) vs. (6.66±2.05)] were lower than the first evaluation score ( P<0.05). The second scores of depression for female doctors [(6.15±1.37) vs . (6.68±2.06)], doctors in medical laboratory department [(6.02±1.40) vs . (6.69±1.88)], doctors from tertiary hospital [(6.13±1.41) vs. (6.51±1.90)], doctor with different training durations [(6.04±1.42) vs . (6.50±2.02), (6.12±1.34) vs . (6.57±1.97)] and the total score of doctors [(6.09±1.37) vs . (6.54±1.99)] were lower than those of the first evaluation ( P < 0.05). The anxiety score of the second evaluation in the control group was higher in male physicians [(6.63±1.15) vs . (6.11±1.76)] than the first evaluation ( P < 0.05). Compared with the second evaluation data of doctors in the two groups, in terms of anxiety scores, the scores of doctors at all levels and total scores in the intervention group were lower than those in the control group ( P < 0.05); in terms of depression score, the scores of female visiting doctors, doctors from tertiary hospitals, doctors with refresher training duration of 6 months and total score were lower than those of the control group ( P < 0.05). Conclusion:The application of humanistic management to strengthen the management of refresher physicians can improve the psychological state of refresher doctors to a certain extent, especially alleviate the anxiety state, which is a worthy promotion of refresher management mode.

ABSTRACT

OBJECTIVES@#With the rapid development of aging population, the number of elderly patients undergoing posterior lumbar spine surgery continues to increase. Lumbar spine surgery could cause moderate to severe postoperative pain, and the conventional opioid-based analgesia techniques have many side effects, which are barriers to the recovery after surgery of the elderly. Previous studies have demonstrated that erector spinae plane block (ESPB) could bring about favorable analgesia in spinal surgery. As far as the elderly are concerned, the analgesic and recovery effects of ESPB on posterior lumbar spine surgery are not completely clear. This study aims to observe the effects of bilateral ESPB on elderly patients undergoing posterior lumbar spine surgery, and to improve the anesthesia techniques.@*METHODS@#A total of 70 elderly patients of both sex, who were selected from May 2020 to November 2021, scheduled for elective posterior lumbar spine surgery, and in the age of 60-79 years, with American Society of Anesthesiologists class Ⅱ-Ⅲ, were divided into a ESPB group and a control (C) group using a random number table method, with 35 patients each. Before general anesthesia induction, 20 mL 0.4% ropivacaine was injected to the transverse process of L3 or L4 bilaterally in the ESPB group and only saline in the C group. The score of Numerical Rating Scale (NRS) indicating pain at rest and on movement within 48 h after operation, time of first patient control analgesia (PCA), cumulative consumptions of sufentanil within 48 hours, Leeds Sleep Evaluation Questionnaire (LSEQ) scores on the morning of day 1 and day 2 after operation, Quality of Recovery-15 (QoR-15) scores at 24 and 48 h after operation, full diet intake times, perioperative adverse reactions such as intraoperative hypotension, postoperative dizziness, nausea, vomiting, and constipation were compared between the 2 groups.@*RESULTS@#A total of 70 patients were enrolled and 62 subjects completed the study, including 32 in the ESPB group and 30 in the C group. Compared with the C group, the postoperative NRS scores at rest at 2, 4, 6, and 12 h and on movementat at 2, 4, and 6 h were lower, time of first PCA was later, sufentanil consumptions were significantly decreased during 0-12 h and 12-24 h after operation, LSEQ scores on the morning of day 1 and QoR-15 scores at 24 and 48 h after operation were higher, full diet intakes achieved earlier in the ESPB group (all P<0.05). There were no significant differences in the incidences of intraoperative hypotension, postoperative dizziness, nausea, vomiting, and constipation between the 2 groups (all P>0.05).@*CONCLUSIONS@#Providing favorable analgesic effects with reduced opioids consumption, bilateral ESPB for posterior lumbar spine surgery in the elderly patients could also improve postoperative sleep quality, promote gastrointestinal functional restoration, and enhance recovery with few adverse reactions.

ABSTRACT

OBJECTIVES@#The number of gestational women has been increased in recent years, resulting in more adverse pregnancy outcomes. It is crucial to assess the coagulation function of pregnant women and to intervene in a timely manner. This study aims to analyze the influencing factors on thrombelastography (TEG) and explore the evaluation of TEG for gestational women.@*METHODS@#A retrospective study was conducted on 449 pregnant women who were hospitalized in the obstetrics department in Xiangya Hospital of Central South University from 2018 to 2020. We compared the changes on the TEG parameters among normal pregnant women between different age groups, different ingravidation groups, and different stages of pregnancy groups. The influence on TEG of hypertensive disorders in pregnancy (HDP) and gestational diabetes mellitus (GDM) as well as two diseases synchronization was explored.@*RESULTS@#Compared with the normal second trimester women, the R values and K values of TEG were increased, and α angle, CI values and LY30 values were decreased in third trimester women (all P<0.05). Compared with normal group, the R values and CI values of TEG of the HDP group have significant difference (both P<0.05). There were no significant difference of TEG between the GDM group, the HDP combined with GDM group and the normal group (all P>0.05). Multiple linear regression analysis showed that the influencing factors for R value in TEG were weeks of gestation (P<0.001) and mode of conception (P<0.05), for α angle was weeks of gestation (P<0.05), for MA value was mode of conception (P<0.05), and for CI value was weeks of gestation (P<0.05). The analysis of correlation between TEG with platelet (PLT) and coagulation routines represented that there was a correlation between TEG R values and activated partial thromboplastin time (APTT) (P<0.01), and negative correlation between TEG CI values and APTT (P<0.05). There was a negative correlation between TEG K values and FIB (P<0.05). The correlation of α angle (P<0.05), MA values (P<0.01) and CI values (P<0.05) with FIB were positive respectively.@*CONCLUSIONS@#The TEG parameters of 3 stages of pregnancy were different. The different ingravidation approach has effect on TEG. The TEG parameters were consistent with conventional coagulation indicators. The TEG can be used to screen the coagulation status of gestational women, recognize the abnormalities of coagulation and prevent the severe complication timely.

ABSTRACT

OBJECTIVES@#To investigate the clinical characteristics, pathology, and prognosis of children with diffuse endocapillary proliferative Henoch-Schönlein purpura nephritis (DEP-HSPN).@*METHODS@#A retrospective analysis was performed on the clinical, pathological, and prognosis data of 44 children with DEP-HSPN and 765 children without DEP-HSPN. The children with DEP-HSPN were diagnosed by renal biopsy in Jiangxi Provincial Children's Hospital from January 2006 to December 2021.@*RESULTS@#Among the 809 children with purpura nephritis, 44 (5.4%) had DEP-HSPN, with a mean age of (8±3) years, and there were 29 boys (65.9%) and 15 girls (34.1%). Compared with the non-DEP-HSPN group, the DEP-HSPN group had a significantly shorter time from onset to renal biopsy and a significantly higher proportion of children with respiratory infection or gross hematuria, and most children had nephrotic syndrome. The DEP-HSPN group had significantly higher levels of 24-hour urinary protein, urinary protein grading, microscopic hematuria grading, serum creatinine, and blood urea nitrogen and significantly lower levels of serum albumin and complement C3 (P<0.05). The DEP-HSPN group had a higher pathological grading, with predominant deposition of IgA in the mesangial area and capillary loops, and higher activity scores in the modified semi-quantitative scoring system (P<0.05). The Kaplan-Meier survival analysis showed that there was no significant difference in the renal complete remission rate between the two groups (P>0.05).@*CONCLUSIONS@#Children with DEP-HSPN have a rapid onset, severe clinical manifestations and pathological grading, and high activity scores in the modified semi-quantitative scoring system. However, most of the children with DEP-HSPN have a good prognosis, with a comparable renal complete remission rate to the children without DEP-HSPN.

ABSTRACT

Objective:To analyze the clinical features of patients with severe dengue (SD) in Guangdong Province, and to improve the understanding of the diagnosis and treatment of SD in China.Methods:The clinical data, laboratory examination and etiological test results of 257 SD cases from 29 dengue fever designated hospitals in Guangdong Province from January 1, 2013 to December 31, 2019 were respectively collected. The relevant indicators of the criteria for severe organ involvement were quantified. Logistic regression analysis was performed to analyze the risk factors for the development of multiple organ failure in SD patients.Results:Among the 257 SD patients, age was (64.1±20.1) years old, with 65.4%(168/257) of them ≥60 years old, 142 were male and 115 were female. One hundred and fifty-two (59.1%) patients had underlying conditions, including 115(44.7%) patients with hypertension. The clinical manifestations were mainly fever (98.4%(253/257)), fatigue (70.0%(180/257)), cough or expectoration (44.4%(114/257)), lethargy or irritability (39.3%(101/257)), vomiting (30.4%(78/257)), abdominal pain or tenderness (20.6%(53/257)), hepatomegaly (2.3%(6/257)), bleeding tendency (59.5%(153/257)), and pleural effusion or ascites (43.6%(112/257)). Platelet count levels were decreased in 90.9%(231/254) of the cases, and 97.1%(234/241) of patients had normal or decreased hematocrit. The most common of severe manifestations were severe organ involvement (61.1%(157/257)), followed by severe bleeding (37.0%(95/257)) and severe plasma leakage (30.0%(77/257)). Severe organ involvements were more common in the kidney (27.6%(71/257)) and heart (26.8%(69/257)). Multivariate logistic regression analysis showed that age (odds ratio ( OR)=1.051, 95% confidence interval ( CI) 1.004 to 1.100, P=0.035), hypertension ( OR=5.224, 95% CI 1.272 to 21.462, P=0.022), elevated aspartate aminotransferase (AST) level ( OR=1.002, 95% CI 1.001 to 1.003, P=0.001), blood urea nitrogen (BUN) ( OR=1.050, 95% CI 1.005 to 1.098, P=0.030), and international normalized ratio (INR) ( OR=4.604, 95% CI 1.601 to 13.238, P=0.005) were risk factors for the development of multiple organ failure in SD patients. The detection results of serum samples form 113 SD patients in acute phase showed that dengue virus (DENV)-1 accounted for 89.4%(101/113), DENV-2 accounted for 9.7%(11/113), and DENV-3 accounted for 0.9% (1/113). Conclusions:Elderly and those with co-existing conditions such as hypertension in SD patients in Guangdong Province are more common. Severe organ involvement such as kidney and heart is the main cause of SD. DENV-1 infection is predominant. Significant elevated levels of AST, BUN and INR may be related to a poor prognosis.

ABSTRACT

Aim To evaluate the effects of Rutaecarpine(Rut)on the expression of SIRT1 and the senescence of vascular smooth muscle cells(VSMCs)induced by angiotensin Ⅱ.Methods VSMC senescencewas induced by exposure to AngⅡ(1 μmol·L-1)for 72 h.VSMCs were treated with different concentrations of Rut(0.3, 1, 3 μmol·L-1).TRPV1 competitive antagonist CAPZ(10 μmol·L-1)and AMPK inhibitor Compound C(1 μmol·L-1)were used to explore whether TRPV1/AMPK mediated the protective effect of Rut.The quantity of senescent cells were determined by senescence-associated SA-β-Gal staining, and the intracellular ROS level was measured by(DCFH-DA)fluorescent probe.The migration ability of VSMCs was evaluated by Wound-healing assay combined with Transwell assay.The protein level of longevity protein SIRT1 and senescence-related proteins p53, p21 and AMPK phosphorylation level were detected by Western blot.Results Rut significantly inhibited Ang Ⅱ-induced VSMC senescence and ROS production and prevented VSMCs migration.Preprocessing of TRPV1 antagonist CAPZ could abolish the protective effect of Rut.Ang Ⅱ inhibited the expression of longevity protein SIRT1.Rut recovered SIRT1 expression in a dose-dependent manner, while prevented the up-regulation of senescence-related proteins p53 and p21.Ang Ⅱ inhibited AMPK phosphorylation, pre-treatment with Rut restored AMPK phosphorylation level.CAPZ and Compound C eliminated the up-regulating function of Rut on SIRT1 expression.Conclusions Rut up-regulates the expression of SIRT1 and prevents the senescence and migration of VSMCs induced by Angiotensin Ⅱ, which is related to activation of the TRPV1/AMPK signaling pathway.

ABSTRACT

ObjectiveTo observe the therapeutic effect of Radix Paeoniae Rubra-Radix Aconiti Lateralis on acute-on-chronic liver failure (ACLF) rats and its effect on M1/M2 macrophage polarization. MethodMale SD rats were randomly divided into normal group, model group, positive group (lactulose, 1.8 g·kg-1) and traditional Chinese medicine (TCM) group (Radix Paeoniae Rubra-Radix Aconiti Lateralis, 5.85 g·kg-1), six in each group. The ACLF rat model was established by subcutaneous and tail vein injection of bovine serum albumin combined with intraperitoneal injection of D-galactosamine+lipopolysaccharide. Then the modeled rats were intervened with corresponding drugs for one week. The normal group and model group were given the same dose of distilled water. The histopathological changes of liver tissue were observed by hematoxylin-eosin (HE) staining. The mRNA and protein expression levels of CD86, inducible nitric oxide synthase (iNOS), CD206 and arginase 1 (Arg1) were detected by real-time polymerase chain reaction (Real-time PCR), Western blot and immunohistochemistry. ResultCompared with the conditions in the normal group, pseudolobule formation in liver tissue and morphological changes and necrosis of hepatocytes were observed in ACLF rats, accompanied by a large number of inflammatory cell infiltration. Moreover, the mRNA and protein expression levels of CD86, iNOS were up-regulated(P<0.01). Compared with the model group, the treatment groups had improved necrosis and inflammatory infiltration of hepatocytes, down-regulated mRNA and protein expression of CD86 and iNOS (P<0.01) and up-regulated mRNA and protein expression of CD206 and Arg1 (P<0.05, P<0.01), with the up regulation in the TCM group better than that in the positive group. ConclusionACLF rats had unbalanced M1/M2 macrophage polarization, and the imbalance shifted towards M1. Radix Paeoniae Rubra-Radix Aconiti Lateralis inhibited the activation of M1 macrophages and reduced the inflammatory response of liver failure by promoting the polarization of liver macrophages towards M2.

ABSTRACT

OBJECTIVES@#To study the effect of intrapartum antibiotic prophylaxis (IAP) of group B streptococcus (GBS) infection on the incidence and bacteriological profile of early-onset neonatal sepsis (EONS).@*METHODS@#A retrospective analysis was performed on the medical data of 494 pregnant women with positive GBS screening results and 526 neonates born by these women. According to whether the pregnant woman received IAP, the neonates were divided into two groups: IAP (n=304) and control (n=222). The two groups were compared in terms of clinical indices, incidence rate of EONS, and distribution of pathogenic bacteria in blood culture.@*RESULTS@#Compared with the control group, the IAP group had a significantly lower proportion of children with abnormal clinical manifestations (P<0.001) and a significantly lower incidence rate of EONS (P=0.022). In the IAP group, Escherichia coli (2.3%) was the most common type of pathogenic bacteria in blood culture of the neonates with EONS, while GBS (3.2%) was the most common type of pathogenic bacteria in the control group. The IAP group had a significantly higher detection rate of ampicillin-resistant Escherichia coli than the control group (P=0.029).@*CONCLUSIONS@#Although IAP can significantly reduce the incidence rate of EONS in neonates born to pregnant women with positive GBS screening results, the infection rate of ampicillin-resistant Escherichia coli may increase after IAP treatment. Therefore, it is needed to enhance the monitoring of blood culture results of neonates with EONS and timely adjust treatment plan according to drug susceptibility test results.

ABSTRACT

Objective:To examine the influencing factors of endothelial injury using the structural equation model (SEM).Methods:A total of 6 861 asymptomatic individuals free of cardiovascular disease underwent health examinations at the health management center of the third Xiangya hospital, Central South University from May 2015 to August 2020. And collected their questionnaire and checkup data. Spearman′s rank correlation coefficient was used to analyze metabolic factors and brachial artery flow-mediated dilatation (FMD). Exploratory factor analysis (3 430/6 861) and confirmatory factor analysis (3 431/6 861) were conducted on the diet items. An SEM was constructed using the diet pattern data, cardiovascular risk factors and FMD, and using multi-path regression analysis to determine the correlation between the indicators.Results:Based on the factor analysis, diet items were divided into three patterns: healthy food, meat, and supplementary food. The SEM indicated that age ( β=0.27) and blood pressure ( β=0.12) had obvious effects on low FMD. Triglyceride ( β=0.03), fasting blood glucose ( β=0.04), and body mass index ( β=0.08) were positively correlated with low FMD. On the upstream, healthy food was negatively correlated with blood pressure ( β=-0.04) and body mass index ( β=-0.04), meat was positively correlated with triglyceride ( β=0.33), blood pressure ( β=0.06), fasting blood glucose ( β=0.20), and body mass index ( β=0.16), and supplementary food was negatively correlated with fasting blood glucose ( β=-0.30). This was the only pattern that was directly correlated with FMD ( β=0.05). Conclusions:SEM is an effective method to analyze the influence of various risk factors on the population and the relationship between individual indicators. This study revealed direct and indirect correlations between age, diet pattern, cardiovascular-metabolic risk, and FMD impairment. Comprehensive control of dietary patterns and metabolic indicators could prevent and improve early cardiovascular injury.

ABSTRACT

Persistent fetal vasculature syndrome (PFVS) is a rare congenital vitreous dysplasia, which is classified as anterior, posterior and combined types according to the location of the vascular abnormalities. The clinical manifestations of PFVS are diverse, and early surgical intervention is very important. The main objective of surgical treatment is to remove the anterior and posterior traction between fibrovascular membranes and retina as well as lens, and to reconstruct clear visual axis. Surgical treatments include pupilloplasty, lensectomy with or without intraocular lens implantation and vitrectomy via limbal or scleral approach. For new technologies, the applications of ophthalmic viscosurgical device and femtosecond lasers have desirable results . In addition to focusing on improving the success rate of surgery, it is also necessary to systematically and comprehensively assess the overall preoperative condition and postoperative visual function of the patients. PFVS eyes have limited improvement in postoperative vision, which is related to the extent of lesion involvement and the occurrence of complications. Eyes with macular dysplasia and tractional retinal detachment, as well as elongated ciliary process, have a poor prognosis of vision after surgery. How to improve postoperative vision in the eye affecting the posterior segment of the eye with PFVS from the microscopic anatomical relationship between the fibrous vascular pedicle and the retina is worth further study. On the other hand, reducing surgical trauma and optimizing surgical procedures in order to improve postoperative visual acuity and reduce postoperative complications are also the key research directions of future PFVS treatments.

Objective:To analyze the prehospital predictors of large-vessel occlusion (LVO) in acute ischemic stroke.Methods:This study recruited patients who had developed LVO for less than 24 hours and had a National Institute of Health Stroke Scale (NIHSS) score ≥ 8 and who received treatment in Lu'an People's Hospital from December 2018 to November 2020. The included patients were divided into LVO and LVO-free groups according to the presence of a large-vessel occlusion determined by magnetic resonance angiography, CT angiography, and digital subtraction angiography. Baseline data (sex, age, disease history, life history, and medication history), NIHSS subscale score, and blood pressure at admission were compared between LVO and LVO-free groups. The efficacy of the factors that were screened for predicting LVO in acute ischemic stroke were compared with the that of commonly used scales.Results:A total of 761 patients with acute ischemic stroke who had an NIHSS score ≥ 8 were included in the final analysis. Among them, 228 patients had an LVO and 533 patients had no LVO. There were significant differences in the proportions of patients with atrial fibrillation ( OR = 5.230, 95% CI = 3.400-8.043, P < 0.001) and systolic blood pressure ≤ 170 mmHg ( OR = 5.181, 95% CI = 3.327-8.068, P < 0.001) between the two groups. Conclusion:Atrial fibrillation and systolic blood pressure ≤ 170 mmHg are greatly associated with the presence of large-vessel occlusion in acute ischemic stroke.

ABSTRACT

Objective:To investigate the pharmacokinetics of sugammadex in reversal of postoperative residual neuromuscular blockade in obese patients.Methods:Sixteen patients of both sexes, aged 18-65 yr, of American Society of Anesthesiologists physical statusⅠ or Ⅱ, with body mass index of ≥25 kg/m 2, scheduled for elective laparoscopic bariatric surgery, were selected.The patients were divided into 2 groups ( n=8 each) according to the degree of obesity: group O (25 kg/m 2≤BMI<40 kg/m 2) and group M (BMI≥40 kg/m 2). In group O and group M, vecuronium was administered by closed-loop muscle relaxant injection system to maintain moderate neuromuscular blockade.The administration was stopped at the end of surgery, and sugammadex 2 mg/kg was injected according to corrected body weight (CBW) of patients when the muscle relaxation monitoring T 2 recovered naturally.The recovery time of neuromuscular blockade and the occurrence of residual neuromuscular blockade within 3 h after surgery were recorded.Arterial blood samples were collected at 2, 3, 5, 10, 15, 20, 30, 60, 120, 240, 360 and 480 min after administration of sugammadex.The concentration of sugammadex in plasma was determined by ultra-performance liquid chromatography-mass spectrometry.The pharmacokinetic parameters were calculated with PKSolver software. Results:No residual neuromuscular blockade occurred, and the pharmacokinetics of sugammadex in plasma were consistent with the linear non-compartmental model in the two groups.Compared with group O, apparent clearance was increased ( P<0.05), and no significant change was found in other pharmacokinetic parameters, recovery time of neuromuscular blockade and concentrations of sugammadex in plasma at different time point ( P>0.05) in group M. Conclusion:The pharmacokinetics of sugammadex in reversal of postoperative residual neuromuscular blockade in obese patients are consistent with the linear non-compartmental model, and the clearance of sugammadex is higher in morbidly obese patients.

ABSTRACT

Phospholysine phosphohistidine inorganic pyrophosphate phosphatase (LHPP) is a highly conserved histidine phosphatase from worms to humans in evolution. Recent studies have shown that LHPP, as a tumor suppressor, can inhibit the proliferation, growth and migration of the cells and promote apoptosis by participating in the regulation of various cell signaling pathways and protein phosphorylation. Therefore, the deeply study on the mechanism of LHPP is helpful to explore the best diagnostic markers and therapeutic targets for related tumors, which is essential for improving the prognosis of related tumors.

ABSTRACT

Tianxiong has been used as a Chinese medicinal in China for thousands of years, and the earliest record can be traced back to the Shennong's Classic of Materia Medica. It is effective in dispersing wind, dissipating cold, and replenishing fire to streng-then yang. To clarify the origin of Tianxiong, the present herbalogical study reviewed the ancient and modern literature from the origin, processing, and clinical efficacy. Before the Tang Dynasty, although the description of Tianxiong was quite superficial, an apparent difference between Tianxiong and Fuzi was recognized. In the Tang and Song Dynasties, Tianxiong and Fuzi were mistakenly recognized to be prepared from a same plant since their raw materials came from artificial cultivation. Medical literature in the Ming and Qing Dynasties mostly followed the previous records, with the origin of Tianxiong remaining controversial. There were three mainstream views about the origin of Tianxiong according the ancient medical books. First, Tianxiong was a kind of Aconiti Radix(Chuanwu) without attachment of Fuzi. Second, Tianxiong was the large Fuzi. Third, Tianxiong derived from Aconiti Kusnezoffii Radix(Caowu) about 10 cm in length. By contrast, Fuzi in a large size was simply regarded as Tianxiong in modern times. The processing methods were diversified in the ancient times, and the fire-processing was continuously applied. With the deepening of the research on the efficacy and detoxification mechanism, more methods were discovered, such as processing with ginger juice, child's urine and alcohol. As for modern times, the processing of Tianxiong has not been nearly passed down. The characteristic processing of Tianxiong only handed down in Sichuan province and Lingnan area, which can be discriminated by the last step. The efficacies of Tianxiong can be directly understood from its literal name, including dispersing wind, dissipating cold, and replenishing fire to assist yang. Nowadays, Tianxiong is mostly used to strengthen yang.

ABSTRACT

Retinopathy of prematurity (ROP) is a proliferative vascular retinal disease. Cryotherapy, laser photocoagulation, intravitreal injection of anti-vascular endothelial growth factor, scleral buckling surgery and vitrectomy are the main treatments. Treated with cryotherapy or laser photocoagulation or intravitreal injection of anti-vascular endothelial growth factor, patients with a history of ROP have thicker foveas, and the morphology of the fovea and the development of the retinal vessels in the macular area are affected, resulting in abnormal vision development. However, the specific mechanisms by which different treatments of ROP affecting the development of the macula are not yet clear. It still need further study with large samples to verify and explore, whether changes in the levels of intraocular vascular endothelial growth factor changing the process of normal macular development and how the abnormal development of the macula affects visual function.

ABSTRACT

Objective:To investigate the relationship between genotype and phenotype in children with CRB1 mutated Leber congenital amaurosis (LCA) and early onset retinal dystrophy (EOSRD). Methods:A retrospective clinical study. From January 2013 to December 2019, 10 children with CRB1 mutated LCA/EOSRD were enrolled in the study. The patients were identified as CRB1 mutation by the second generation targeted capture sequencing, Sanger sequencing and the family segregation analysis. All children underwent electroretinogram (ERG) and fundus examination. At the same time, 6 cases were examined by optical coherence tomography (OCT); 1 case was examined by fluorescein fundus angiography (FFA), 7 cases were examined by wide-angle laser scanning ophthalmoscope (UWF SLO). Results:There were 6 cases of LCA and 4 cases of EOSRD in 10 patients with CRB1 gene mutations. The average age of first visit was 3.61 years old. The light and dark wave of ERG was flat in 6 cases, and decreased in 4 cases. A total of 19 pathogenic mutations were detected. There were 1 homozygous mutation and 9 compound heterozygous mutations. There were 4, 2 and 1 cases of "copper-coin" like, "salt and pepper" like and "osteocyte" like pigment changes in retina, 1 case of "crystalline pigment" change and 2 cases of macular pigment scar. In 7 cases of UWF SLO examination, different degrees of para-arteriolar pigment epithelium retention (PPRPE) were found in the middle and peripheral fundus. In 6 cases examined by OCT, the outer layer of retina atrophied and the band of ellipsoid disappeared. Symmetrical cystoid macular edema, splitting cystoid macular degeneration and adhesion of epi-macular membrane to optic disc and macular area were found in 1 case, respectively, the retinal structure was rough and thickened, and the fovea became thinner in 3 cases. In FFA examination, 1 case showed uveitis-like changes with late optic disc fluorescein staining, macular fluorescence accumulation, strong fluorescence diffusing along the blood vessels in each quadrant, peripheral PPRPE of "frost-branch" like strong fluorescence. Conclusion:The relationship between genotype and phenotype of CRB1 mutation is complex, and PPRPE is a common characteristic change.

ABSTRACT

Objective:To describe the unqualified situation of infant formula food by supervision and sampling inspection in China, and then recommend appropriate countermeasures. Methods:The results of supervision and sampling inspection of infant formula food were summarized from 2015 through 2020 in China, and the unqualified items were classified and analyzed. Results:From 2015 through 2020, a total of 30 252 batches of infant formula food were sampled and examined in China, in which 187 batches were determined to be unqualified with an overall unqualified rate of 0.62% (187/30 252). Content of items in 82 batches of samples did not meet the national standards for food safety, accounting for 43.85% (82/187) of the total number of unqualified batches. Labels in 105 batches were unqualified, accounting for 56.15% (105/187). Generally, the unqualified rate of infant formula food showed an overall downward trend over years, with a 1.8% of decrease between 2020 (0.03%) and 2015 (1.83%). The main problems in the unqualified infant formula food in China were minerals, vitamins, optional ingredients, microorganisms and conventional nutrients, which accounted for 39.50% (94/238), 15.97% (38/238), 14.29% (34/238), 10.50% (25/238) and 10.08% (24/238) of the total unqualified items, respectively. Conclusion:Food manufacturers should strictly implement the principal responsibility of food safety, and government regulatory sectors should continue to strengthen the supervision to ensure the quality and safety of infant formula food.
