Objective:To observe the impact of core stability training in the sling exercise therapy pattern on the balance of stroke survivors.Methods:Sixty stroke survivors were randomly divided into a control group ( n=30) and an experimental group ( n=30). In addition to routine rehabilitation training, the control group received traditional core stability training, while the experimental group underwent core stability training applying the sling exercise therapy pattern. Before and after 4 weeks of training, the standing balance of both groups was evaluated using the Prokin balance trainer, with the length and area of motion recorded when performing the balance test with the eyes open and closed. Surface electromyography was used to record the average EMG (AEMG) values of the bilateral erector spinae and multifidus muscles during the balance testing. Results:After the 4 weeks of training the length and the area of progression of the center of the pressure were both significantly smaller for both groups than before the training with the eyes both open and closed. The average length and area in the experimental group were significantly less than among the controls. The AEMG values recorded during the balance tests were significantly higher than those before the intervention for both groups, with the multifidus muscle averages on the affected side significantly greater in the experimental group than among the controls when performing the balance test with the eyes closed.Conclusion:Core stability training in the sling exercise therapy pattern is superior to conventional core stability training because it can better improve the balance of stroke survivors.

Objective:To analyze risk factors for diabetes mellitus in patients with vitiligo, and to construct and validate a prediction model.Methods:A total of 110 vitiligo patients with diabetes mellitus (comorbidity group) and 4 505 vitiligo patients without diabetes mellitus (control group) were collected from the medical record database in Xijing Hospital, the Fourth Military Medical University from January 2010 to October 2021, and matched for gender and age at a ratio of 1∶4 by using a propensity score method. After matching, the matched pairs were randomly divided into a training set and a test set at a ratio of 4∶1. Univariate and multivariate logistic regression analyses were used to assess demographic and clinical characteristics of patients in the training set, screen differential factors, and construct a prediction model. A five-fold cross-validation method was used for internal validation after construction of the prediction model. The discrimination (area under the curve [AUC]) , calibration (Hosmer-Lemeshow test) and accuracy (sensitivity, specificity, positive predictive value, and negative predictive value) of the prediction model were evaluated in the test set.Results:A total of 107 cases in the comorbidity group and 428 cases in the control group were successfully matched. The training set included 430 cases, and the test set included 105 cases. Based on multivariate logistic regression results, a total of 6 factors were included in the prediction model, including course of vitiligo (odds ratio [ OR] = 1.04, 95% confidence interval [ CI]: 1.02 - 1.07, P<0.001) , high-sugar/high-fat/high-salt diet ( OR = 3.19, 95% CI: 1.38 - 7.38, P = 0.007) , family history of diabetes ( OR = 23.23, 95% CI: 9.72 - 55.50, P<0.001) , metabolic comorbidities ( OR = 12.53, 95% CI: 5.60 - 28.07, P<0.001) , autoimmune comorbidities ( OR = 5.89, 95% CI: 2.52 - 13.76, P<0.001) , and acral vitiligo ( OR = 3.84, 95% CI: 1.45 - 10.19, P = 0.007) . Five-fold cross-validation results showed a good predictive performance of the prediction model, with the AUC being 0.902 (95% CI: 0.864 - 0.940) in the training set and 0.895 (95% CI: 0.815 - 0.974) in the test set. The prediction model also showed favourable discrimination (AUC =0.814, 95% CI: 0.715 - 0.913) , calibration (Hosmer-Lemeshow test, P = 0.068) , and accuracy (sensitivity = 0.810, 95% CI: 0.574 - 0.937; specificity = 0.786, 95% CI: 0.680 - 0.865; positive predictive value = 0.486, 95% CI: 0.317 - 0.657; negative predictive value = 0.943, 95% CI: 0.853 - 0.982) in the test set. Conclusion:A risk prediction model was constructed for diabetes mellitus in patients with vitiligo based on 6 factors (course of vitiligo, high-sugar/high-fat/high-salt diet, family history of diabetes, metabolic comorbidities, autoimmune comorbidities, and acral vitiligo) , which showed favourable discrimination, calibration and accuracy, and might provide a reference for screening the high-risk diabetic population in vitiligo patients.

Objective To analyze the clinical features of patients with coronavirus disease 2019 (COVID-19) in Shanghai and to investigate the risk factors for disease progression to severe cases. Methods The clinical data of 292 adult patients with COVID-19 hospitalized in Shanghai Public Health Clinical Center from January 20, 2020 to February 10, 2020 were retrospectively analyzed, including 21 severe patients and 271 mild patients. The demographic characteristics, epidemiological history, history of underlying diseases and laboratory examinations were compared between the two groups. Measurement data were compared using t test or Mann-Whitney U test. The count data were compared using hi-square test. The binary logistic regression equation was used to analyze the risk factors for the progression of patients to severe cases. Results Among the 292 patients, 21 were severe cases with the rate of 7.2% (21/292). One patient died, and the mortality rate was 4.8% in severe patients. The severe patients aged (65.0±15.7) years old, 19 (90.5%) were male, 11 (52.4%) had underlying diseases, 7 (33.3%) had close relatives diagnosed with COVID-19. The mild patients aged (48.7±15.7) years old, 135 (49.8%) were male, 74 (27.3%) had underlying diseases, 36 (13.3%) had close relatives diagnosed with COVID-19. The differences between two groups were all significant statistically ( t =-4.730, χ 2 =12.930, 5.938 and 4.744, respectively, all P <0.05). Compared with the mild patients, the levels of absolute numbers of neutrophils, alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, creatinine, serum cystatin C, C reactive protein (CRP), procalcitonin , D -dimer, pro-B-type natriuretic peptide (proBNP), serum myoglobin, creatine kinase (CK), creatine kinase isoenzyme (CK-MB), serum troponin I (cTnI) in severe patients were all significantly higher ( U =2 091.5, 1 928.0, 1 215.5, 729.0, 1 580.5, 1 375.5, 917.5, 789.5, 1 209.0, 1 434.0, 638.0, 964.5, 1 258.0 and 1 747.5, respectively, all P <0.05), while the levels of lymphocyte count, albumin, transferrin, CD3 + T lymphocyte count, CD8 + T lymphocyte count and CD4 + T lymphocyte count in severe patients were all significantly lower ( U =1 263.5, t =4.716, U =1 214.0, 962.0, 1 167.5 and 988.0, respectively, all P <0.05). Further logistic regression analysis showed that the albumin (odds ratio ( OR )=0.806, 95% CI 0.675-0.961), CRP ( OR =1.016, 95% CI 1.000-1.032), serum myoglobin ( OR =1.010, 95% CI 1.004-1.016), CD3 + T lymphocyte count ( OR =0.996, 95% CI 0.991-1.000) and CD8 + T lymphocyte count ( OR =1.006, 95% CI 1.001-1.010) at admission were independent risk factors for the progression of COVID-19 patients to severe illness (all P <0.05). Conclusions Severe cases of patients with COVID-19 in Shanghai are predominantly elderly men with underlying diseases. Albumin, CRP, serum myoglobin, CD3 + T lymphocyte count and CD8 + T lymphocyte count could be used as early warning indicators for severe cases, which deserve more clinical attention.

OBJECTIVE： To introduce the pharmaceutical care for refractory mycoplasma pneumoniae （MP） pneumonia combined with cerebral infarction in child by clinical pharmacist， and to improve further understanding of MP-induced cerebral infarction and the management level of the clinical pharmacist. METHODS： Clinical pharmacist provided whole course pharmaceutical care for a child case of refractory PM pneumonia complicated with cerebral infarction admitted to the Children’s Hospital of Fudan University in Oct. 2018. The drug use in anti-infection， anti-inflammatory， treatment of cerebral infarction， possible drug interactions and suspected ADR were analyzed during treatment. RESULTS： The child admitted to the hospital for treatment due to MP pneumonia. During the treatment， the child suffered from cerebral infarction symptoms. The child was given a series of treatment programs， such as Azithromycin for injection for anti-infection， Methylprednisolone sodium succinate for injection for anti-inflammation， Nadroparin calcium injection for anticoagulation， Mannitol injection for reducing intracranial pressure， Dextran 40 glucose injection anti-thrombosis， Compound glycyrrhizin injection for protecting liver function， Hydrotalcite tablets for protecting gastric mucosa， intravenous immunoglobulin symptomatic supportive treatment. During the treatment， due to the poor therapeutic effect of Azithromycin for injection， it was considered that the patient may have cerebral infarction caused by refractory MP infection， so the patient’s prognosis was good when Azithromycin injection was replaced with Levofloxacin hydrochloride injection for anti-infection. For the increase of liver enzyme during the treatment， clinical pharmacist suggested that anti-infection combined with liver protection was provided   for the child and then the liver enzyme returned to normal. During the treatment， clinical pharmacist mainly monitored the interaction and possible adverse reactions among anticoagulants， glucocorticoids， liver protecting drugs， drugs for reducing cranial pressure， antipyretic and analgesic drugs， and at the same time， made medication publicity and education for the family members of the child， and inform them of the adverse reactions of drugs to be paid attention to and the precautions for taking stomach protecting drugs， glucocorticoids and other drugs. CONCLUSIONS： Cerebral infarction caused by refractory MP pneumonia in children is because of excessive immune response directly or indirectly mediated by MP. The principle of treatment is to inhibit the inflammatory response， to solve the primary disease， and symptomatic supportive treatment. Multi-drug combination is needed in the course of treatment， so it is more necessary for the clinical pharmacist to participate in the whole process and to manage the drug refinement and ensure the safety of drug use.

Objective To evaluate the sleep structure of rapid eye movement sleep disorder (RBD) patients and its correlations with emotional state,autonomic nerve system function symptoms,and sleep quality.Methods Twenty-two RBD patients examined in our hospital from October 2014 to May 2016 who complained of behavior disorders and conformed diagnosis by video-polysomnography (v-PSG) were chosen as RBD group;23 healthy gender,age and education-level matched subjects confirmed without RBD by v-PSG were selected as control group.Their emotional state,autonomic nerve function and sleep quality were assessed by center for epidemiological survey depression scale (CES-D),apathy evaluation scale (AES),scale for outcomes in PD for autonomic symptoms (SCOPA-AUT),and scale for outcomes in PD for sleep (SCOPA-SLEEP).The differences in sleep structures,periodic leg movement index (PLMI),apnea hypopnea index (AHI) and arousal index between RBD group and control group were compared.The differences of scores of emotional state,autonomic nerve system function symptoms were compared between the two groups.The correlations of sleep structure with emotional state,autonomic nerve system function symptom,and sleep quality in RBD group were analyzed.Results As compared with those of the control group,the proportion of non-rapid eye movement (NREM)-Ⅰ sleep of RBD group was significantly increased,proportions of NREM-Ⅱ sleep and NREM-Ⅲ sleep were statistically reduced,PLMI,CES-D scores,urinary and digestive system questionnaire and overall scores in the RBD group were significantly increased (P＜0.05).In patients from RBD group,CES-D scores were positively correlated with proportion of NREM-I sleep (r=0.520,P=0.000);nighttime sleepiness questionnaire and overall scores were positively correlated with PLMI (r=0.465,P=0.029;r=0.444,P=0.039);daytime sleepiness scores were negatively correlated with proportion of NREM-Ⅲ sleep (r=-0.480,P=0.041);cardiovascular system symptom was correlated with PLMI (r=0.439,P=0.041).Conclusion RBD patients suffer sleep structure disturbance,depression tendency,digestive and urinary system of autonomic nerve symptoms;sleep quality scores and total scores,cardiovascular system symptoms scores are positively correlated with LMI;daytime sleepiness is negatively correlated with reducing phase Ⅲ sleep,CES-D scores are correlated with increasing NREM-I sleep and unbalanced neurotransmitter,especially,5-TH level.
