ABSTRACT
From November 2020 to November 2021, the TEST(Task-Experience- Supervise-Thinking) teaching model was adopted for general practice residency training in teaching clinic of Changfeng Health Service Center of Shanghai Putuo district. The satisfaction of mentors, residents and patients was surveyed with self-assessment questionnaire. The satisfaction scores of mentors, residents and patients were (79.89±0.40), (79.96±0.19) and (49.92±0.40). The adaption of model TEST in teaching clinic is more effective in training of clinical competency, communication ability, management ability and narrative ability for general practice residents. It is also beneficial for mentors to upgrade their teaching ability, as well as for patients to improve their experience and satisfaction for seeking medical service. It is worth popularizing in the community practice base of general resident training.
ABSTRACT
Objective:To establish a prompt based feeding process for premature infants and explore its application effects.Methods:This study was a quasi-experimental research method. Firstly, the best evidence of prompt feeding for premature infants was systematically searched and summarized, and the expert consultation method and clinical practice were used to finally formulate a prompt feeding process for premature infants. The process was applied to clinical practice. A total of 82 hospitalized premature infants in the neonatal intensive care unit of Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from October 2021 to March 2022 were selected as the control group, and routine feeding management was implemented. A total of 86 hospitalized premature infants from April to September 2022 were selected as the observation group. Feeding management for premature infants based on the prompt feeding process was followed, and the feeding efficiency, transition time of full oral feeding, and days of gastric tube retention, hospital stay and the incidence of feeding related complications in the two groups were compared.Results:The effective recovery rates of the two rounds of expert correspondence questionnaires were 100%, and the authoritative coefficients of expert opinions were 0.863 and 0.875, respectively. The Kendall harmony coefficients of expert opinions were 0.156 and 0.202, respectively, and the significance tests were all P<0.05. The total oral feeding rate of the observation group was 59.84%(5 256/8 784), the mixed feeding rate was 12.26%(1 077/8 784), and the tube feeding rate was 27.90%(2 451/8 784). Compared with the control group′s 52.20%(4 698/9 000), 14.68%(1 321/9 000), and 33.12%(2 981/9 000), the difference was statistically significant ( χ2 = 105.21, P<0.05). The transition time of full oral feeding, number of days of gastric tube retention, and hospitalization time in the observation group were (5.14 ± 1.67), (6.13 ± 1.62), and (12.77 ± 1.37) days, respectively. Compared with the control group′s (6.22 ± 1.59), (7.17 ± 1.55), and (13.72 ± 1.72) days, the differences were statistically significant ( t = 4.206, 4.26, 3.97, all P<0.05). The incidence of milk choking, hypoxia, and vomiting in the observation group were 9.30%(8/86), 6.98%(6/86), and 11.63%(10/86), respectively, which were lower than the 23.17%(19/82), 19.51%(16/82), and 34.15%(28/82) of the control group. The difference between the two groups was statistically significant ( χ2 = 5.99, 5.80, 12.16, all P<0.05). Conclusion:The application of prompt feeding process in premature infants can shorten the transition time of full oral feeding, promote the feeding process, reduce the complications caused by poor feeding, and ensure the feeding safety of premature infants.
ABSTRACT
Objective:To explore the effect of family doctor-specialist dual-contract service model on the management of type 2 diabetic patients in the community.Methods:Two hundred patients with type 2 diabetes mellitus (T2DM)who were treated in Changfeng Community Health Service Center between February 2019 and January 2021 were selected as the study objects by cluster sampling method. Patients were randomly divided into study group and control group with 100 cases in each group. The control group was managed with the conventional family doctor contract service, and the study group was managed with the family doctor-specialist double contract service. After one year of management, the fasting blood glucose, 2 h-postprandial blood glucose, glycosylated hemoglobin, diet control, blood glucose monitoring, medication compliance, exercise and other health behaviors, quality of life and satisfaction of patients were compared between two groups.Results:After intervention, fasting blood glucose, 2 h-postprandial blood glucose and glycosylated hemoglobin in the study group were significantly lower than those in the control group ( t=10.29, 8.49, 7.99, all P<0.05); the health related behaviors such as diet control, exercise behavior, blood glucose monitoring, and medication compliance in the study group were significantly better than those in the control group ( t=9.78, 6.72, 39.81, 7.88, all P<0.05); the quality of life in patients of study group was higher than that of the control group ( P<0.05); the satisfaction rate in study group was higher than that of control group (90.0% vs. 69.0%, χ 2=6.39, P=0.031). Conclusion:Compared with conventional family contract service model, the double contract service improves patient self-management, helps to reduce the blood glucose level and gains high patients′ satisfaction, which is worth promoting and applying in the management of type 2 diabetic patients in the community.

ABSTRACT
Objective To investigate the effect of Liu-Shen-Wan on transplanted tumors in mice with colon cancer based on the polarization of M2 macrophages in the tumor microenvironment. Methods We established a subcutaneous transplantation tumor model of mice with CT26 colon cancer. Mice were randomly divided into vehicle, oxaliplatin, and oxaliplatin combined with Liu-Shen-Wan groups. Treatment was administered for three weeks, and tumor volume was measured. All mice were weighed during the administration. After the end of the treatment, the mice were dissected and tumors were photographed and weighed. Spleen index was calculated. The expression levels of IFN-γ and IL-12P40 in serum and related blood biochemical indices were measured. The expression levels of M2 macrophage polarization indices, namely, IL-10 and TGF-β, in serum and tumor tissues were detected. The infiltration degree of M2 macrophages in each group was observed by immunohistochemical experiments. Results The tumor volume and mouse weight in the oxaliplatin combined with Liu-Shen-Wan group significantly decreased compared with those in the vehicle group. The spleen index increased, and the expression levels of IFN-γ and IL-12P40 in serum also significantly increased. The mice had no obvious side effects after the drug treatment. In addition, the expression levels of IL-10 and TGF-β in the serum and tissues of mice in the oxaliplatin combined with Liu-Shen-Wan group significantly decreased. The expression levels of CD68 and CD206 in tumor tissues also decreased. Conclusion The anti-tumor effect of Liu-Shen-Wan on the transplanted tumors of mice with colon cancer is related to the inhibition of M2 macrophage polarization in the tumor microenvironment.
ABSTRACT
Objective:To explore hepatitis B virus (HBV) infection rate of breast feeding to newborn babies of HBV carrying parturient women with hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) double positive.Methods:A prospective cohort study was conducted to include HBsAg and HBeAg double-positive HBV carrying parturient women and their babies born from February 2016 to May 2018 at the Women′s Hospital, Zhejiang University School of Medicine, and 323 parturient women and 323 babies were enrolled. The babies were divided into breast feeding group and artificial feeding group. Chemiluminescence immunoassay and polymerase chain reaction-fluorescent probe method were used to detect the positive rates of serum HBV markers and HBV DNA levels in the newborns <24 h and seven-month-old age, respectively. The statistical method was performed using χ2 test. Results:A total of 297 parturient women were finally included for the analysis, including 149 in the breast feeding group and 148 in the artificial feeding group. There were no significant differences in the positive rates of HBsAg, hepatitis B surface antibody (anti-HBs), HBeAg and HBV DNA>100 IU/mL between the two groups at birth <24 h and seven months of age (all P>0.05). The positive rate of anti-HBs in newborns in the breast feeding group at birth <24 h was 58.39%(87/149), which was lower than 95.97%(143/149) at seven months of age. The HBeAg-positive group was 65.10%(97/149) at birth <24 h in the breast feeding group, which was higher than 13.42%(20/149) at seven months of age. The differences were both statistically significant ( χ2=59.75 and 40.49, respectively, both P<0.01). The positive rates of HBsAg and HBV DNA>100 IU/mL in newborns in the breast feeding group were 2.01%(3/149) and 2.68%(4/149) at birth <24 h, respectively, and those at seven months were 2.68%(4/149) and 2.68%(4/149), respectively. There were no significant differences between the two time points (both P>0.05). In the artificial feeding group, the positive rate of anti-HBs in newborns was 47.97%(71/148) at birth <24 h, which was lower than 95.94% (142/148) at seven months of age. The positive rate of HBeAg in the artificial feeding group was 55.41%(82/148) in newborns at birth <24 h, which was higher than 19.59%(29/148) at seven months of age. The differences were statistically significant ( χ2=85.37 and 39.84, respectively, both P<0.01). The positive rates of HBsAg and HBV DNA>100 IU/mL in newborns in the artificial feeding group at birth <24 h were 4.73%(7/148) and 1.35%(2/148), respectively, and those at seven months were 1.35%(2/148) and 1.35%(2/148), respectively. There were no significant differences between the two time points (both P>0.05). Conclusions:Breast feeding is not a decisive factor for the risk of vertical transmission in HBsAg and HBeAg double-positive HBV carriers. It is recommended that such women could breastfeed under formal precautions.

ABSTRACT
Heat stroke is the most serious type of heat-related diseases, and the induced multiple organ dysfunction syndrome (MODS) is an important cause of death for heat stroke patients. The cardiovascular system is one of the important targets of heat injury. Studies have reported that heat stress can lead to myocardial inhibition, abnormal heart conduction and blood flow redistribution, thus changing the hemodynamic state, leading to obvious abnormalities in electrocardiogram, echocardiography, myocardial injury biological markers and hemodynamic indicators of patients with heat stroke. In this article, the pathophysiological and histological changes and clinical manifestations of heatstroke-induced myocardial injury are reviewed, aiming to provide references for further understanding and research of myocardial damage caused by hyperthermia.
ABSTRACT
Objective@# To prepare the monoclonal antibody against ankyrin repeat domain 22（ANKRD22）and to investigate its expression in colorectal cancer tissues.@*Methods @#The recombinant human ANKRD22 was expressed through E. coli and pET-42a and then used to immunize Balb/c mice after purification. Anti-human ANKRD22 specific monoclonal antibodies were selected by Western blotting with 293T cell lysate highly expressing ANKRD22 as antigen. The expression of ANKRD22 in the tissue microarrays of 112 patients with colorectal cancer was detected by immunohistochemical staining.@*Results @#Four specific monoclonal antibodies against human ANKRD22 were screened out of 93 hybridoma cells,which reacted well with natural human ANKRD22. ANKRD22 was mainly distributed in the cytoplasm of colorectal cancer cells. In 112 cases of colorectal cancer,94 cases were detected positive for ANKRD22 expression,with the positive rate of 83.93%. The expression of ANKRD22 was statistically correlated with the expression of p53 and β-catenin（P<0.05）,but not with age,sex,location of tumors,AJCC stage,Dukes stage,degree of differentiation,lymph node metastasis and mismatch repair gene expression（P>0.05）.@*Conclusion @#The expression level of ANKRD22 was high in colorectal cancer. ANKRD22 might be involved in the carcinogenesis of colorectal epithelium and be a potential diagnostic marker.

ABSTRACT
Heat stroke (HS) is a life-threatening illness characterized by an altered level of consciousness with an elevated core body temperature 40 ℃, which may be further classified as exertional heat stroke (EHS) or classical heat stroke (CHS) according to the etiology of the condition. In recent years, the morbidity of EHS increases year by year. The severity and clinical outcome for an EHS casualty have a strong correlation with the area under the time and temperature curve for heat exposure. The early recognition and rapid cooling body core temperature ≤38.9 ℃ within 30 minutes of EHS results in the best clinical outcome and minimize severe multiple organ dysfunction and death for patients. Cold water immersion (CWI) is considered as an optimum cooling method for the reversal of hyperthermia in EHS. Some alternative modalities have also shown acceptable cooling rate, for example, the subjects immersed in a circulated water bath controlled below 20 ℃, tarp-assisted cooling with oscillation, body cooling unit, undressed, air-conditioned room, the whole body and large vessels placed ice packs, massaging the extremities; cold intravenous saline applied to dehydrated one. It is necessary to monitor body core temperature for hypothermia and/or recurrent hyperthermia, and to provide physical care for shivering, agitation, or concerns with the potential discomfort combativeness that may occur during cooling process. In this paper, pre-hospital recognition, care, monitoring and rapid cooling treatment measures of EHS have been reviewed to provide references for early identification of EHS and scientific, reasonable and effective cooling treatment.

The patient's temperature, blood pressure, intravenous infusion can be monitored during the cooling course. The handles in the hood and the body cover allow the patient to be easily moved and be transferred in rescue. The cooling bag for heat stroke in field has good cooling effect, and are reusable and easy to be carried, operate, monitor and move, with low cost, which make it popularization and application.
ABSTRACT
Objective To understand the prevalence condition of occupational musculoskeletal disorders in nurses,so as to supply scientific evidence for reducing and preventing nurses′occupational injuries.Methods 582 nurses from three level three class -A hospital in Wenzhou were investigated,which were selected by convenience sampling method.Results The prevalence of musculoskeletal disorders was 76.3%.The prevalence of low back pain was highest,which was 58.9%.Among the nurses who had lower back pain,in the past 1 year,43.4%of them had a total duration of illness more than 30 days,18.7% of them reduced daily activities time for more than 30 days,and 22.6% of them had received examination and treatment.The main factors which related to low back pain among nurses were age (OR =2.18,95% CI:1.36 -3.67 ),stoop time (OR =2.24,95% CI:1.08 ~4.36 ), occupational stress(OR =1.82,95%CI:1.14 ~2.89),work fatigue(OR =2.45,95%CI:1.27 ~3.15)and physical exercise(OR =0.63,95%CI:0.44 ~0.89).Conclusion The condition of occupational musculoskeletal disorders is serious,especially low back pain.Interventions related to influencing factors can be taken to reduce the incidence of low back pain.
ABSTRACT
Objective:To establish a bacterial endotoxins testing method for L-oxiracetam injection. Methods: According to the gel-clot technique for bacterial endotoxin inspection and the related regulations in Chinese Pharmacopoeia (2015 edition, volume Ⅳ, general rule 1143), tachypleus amebocyte lysate (TAL) from two different manufacturers were used for bacterial endotoxins test on 3 batches of L-oxiracetam injection with methodology studies. Results:Diluted to 8. 3 mg·ml-1 , the samples showed no interference a-gainst the bacterial endotoxins test. Conclusion:The bacterial endotoxins test method for L-oxiracetam injection is applicable with the endotoxin limit of 3 EU·ml-1 .
