Methods62 patients recovering from cerebral infarction were divided into the control group (30 cases) and motor imagery group (32 cases). All patients received routine treatment and a motor relearning program. Patients in the motor imagery group were given mental practice in activities of the lower limb. They were assessed with Fugl-Meyer Assessments (FMA) and Modified Barthel Index (MBI) before and after treatment. ResultsThe scores of FMA and MBI were improved in the motor imagery group compared with those in the control group (P<0.05) after treatment. ConclusionMotor imagery can facilitate the recovery of lower limb function in patients with hemiplegia.

Objective To learn about the etiology , clinical characteristics and prognosis of infants with cholestasis jaundice. Methods The clinical data of 175 cholestatic patients were retrospectively analyzed , then the prognosis was followed-up with telephone. Results After analyzing the etiology , we found that among 175 patients , there were 42 with biliary atresia , of which 19 infants died , 4 recovered well after liver transplanta-tion , 8 had liver cirrhosis waiting for transplantation , 5 recovered well after Kasai Portoenterostomy and 6 lost contact. There were 2 patients with Bile duct dysplasia and 2 with congenital cholangiectasis and they had posi-tive outcomes. And 29 patients with Cytomegalovirus infection also had positive outcome. There were 16 patients with Heredity metabolic diseases , among which 13 patients were with Citrin protein deficiency; 10 had positive outcomes; 2 lost contact and 1 died. There were 3 patients with tyrosinemia , of which one had positive outcome;one lost contact and another got liver cirohosis waiting for liver transplantation. Four patients with TPN-related cholestasis all had positive outcomes. There were still 80 cases with unkown etiology , but 79 had positive out-comes and 1 case lost. The clinical characteristics showed that the infants with cholestatic jaundice often accom-panied by stool color changed , liver and spleen enlargement and so on , and often complicated with pneumonia , hypoalbuminemia and coagulation dysfunction and so on. Conclusion There are many etiologies for infants with cholestatic jaundice. Early diagnosis and early treatment would benefit the prognosis.

ABSTRACT:Objective To investigate the effects of berberine on matrix metalloproteinases/tissue inhibitors of matrix metalloproteinases (MMPs/TIMPs) in rat periodontitis .Methods Adult male Sprague‐Dawley rats were subjected to thread ligation and porphyromonas gingivalis ( P . gingivalis ) inoculation resulting in periodontitis . Berberine [150 mg/(kg · d)] or vehicle was administered by oral gavage for 4 weeks .Alveolar bone loss and soft‐tissue destruction were determined by micro‐computed tomography (μ‐CT) and HE staining .The contents of tumor necrosis factor‐α(TNF‐α) and interleukin‐1β(IL‐1β) of gingival tissue were examined by ELISA .The expressions of MMP‐2 ,MMP‐9 and TIMP‐2 as well as the phosphorylation of P38 MAPK and NF‐κB were determined by Western blot .Results Significant increases were observed in alveolar bone loss and periodontal soft‐tissue destruction with higher levels of TNF‐α, IL‐1β and MMP‐2/9 expressions and the activities of P38 MAPK and NF‐κB in the experiment periodontitis group .Berberine of [150 mg/(kg · d)] not only improved the periodontal tissue and decreased alveolar bone loss ,but also reduced the contents of TNF‐α,IL‐1βand MMP‐2/9 and increased TIMP‐2 .In addition ,berberine inhibited the phosphorylation of P38 MAPK/NF‐κB .Conclusion Berberine protects against periodontal tissue damage via decreasing MMP‐2 and MMP‐9 expressions but increasing TIMP‐2 expression , which may be induced by inhibition of P38 MAPK/NF‐κB and the anti‐inflammatory effect on rat periodontitis .

Objective To explore fecal bacteria transplantation for the treatment of severe gastrointestinal disease caused by food allergy. Method The therapeutic process of fecal bacteria transplantation for treatment of severe food allergy gastrointestinal disease was retrospectively analyzed, and the related literature was reviewed. Results A 2-year-old boy had onset of intestinal infection and diarrhea was persistent even though he had received adequate anti-infection therapy and supportive treatment. Finally, the patient received the treatment of fecal bacteria transplantation and the symptoms were then improved. No adverse reactions were observed in 2 months of follow-up. In foreign literature, fecal bacteria transplantation in children is mainly applied to clostridium difficile infection (CDI) and inflammatory bowel disease (IBD), with efficiency of 90%- 100% and 55.6% - 100%, respectively. While in the domestic literature, fecal bacteria transplantation in children is mainly used in CDI and antibiotic associated diarrhea, and the effective rate is 100%. No serious adverse reactions were found in all the researches. Conclusion Fecal transplantation is safe and effective in the treatment of children with severe gastrointestinal disease caused by food allergy, but its application in children is not yet mature and needs more in-depth researches.

Objective To observe the effect of scalp acupuncture on cognitive and motor functions of stroke patients in recovery stage.Methods80 stroke patients with cognitive disorder were randomly divided into the scalp acupuncture group (n=41) and control group (n=39). All patients of two groups were treated with routine therapy and rehabilitation training, but the cases of the scalp acupuncture group were added with scalp acupuncture. The cognitive function, motor function and activities of daily living (ADL) of all patients were assessed by delitescence and amplitude of event-related potential (ERP) P300, Fugl-Meyer Assessment (FMA), Barthel Index (BI) respectively before and 3 months after treatment.ResultsAfter treatment, P300 delitescence of the patients in the scalp acupuncture group shorten to 38 ms in average while in the control group shorten only to 17 ms, the therapeutic effect of the scalp acupuncture group was superior to that of the control group ( P<0.05). The scores of FMA and BI of the patients in the scalp acupuncture group were also better than those in the control group ( P<0.05).ConclusionScalp acupuncture can efficiently improve the cognitive function of stroke patients in the recovery stage, and promote the recovery of motor function and ADL.

OBJECTIVETo explore the etiology and clinical characteristics of hypoxic hepatitis (HH) in children.

METHODClinical data of 7 patients with HH in Shenzhen Children's Hospital from January 2011 to March 2014 were retrospectively reviewed.

RESULTSeven cases diagnosed as HH, age from 4 months to 11 years, were admitted to pediatric intensive care unit (PICU), and accounted for 0.32% of patients in PICU during the same period. The primary causes of HH were respiratory failure and cardiac shock caused by severe hand-foot-and-mouth disease, fulminant myocarditis, infant muggy syndrome . Serologic tests for hepatitis B virus, hepatitis C virus, as well as serum antibody and DNA for Epstein-Barr virus and cytomegalovirus were all negative. There was an increase of alanine aminotransferase (ALT) (≥20 time supper limit of normal (ULN), the highest ALT was more than 130 times ULN in all the patients, which was decreased to 2 times ULN from peak within 10 days. There was a significant relationship between ALT and aspartate aminotransferase(AST)in 3 cases(r=1.000, 1.000, and 0.833, respectively, P<0.05), ALT and lactate dehydrogenase (LDH)in 2 cases(r=1.000 and 0.886, respectively, P<0.05), ALT and blood urea nitrogen(BUN)in 1 case(r=1.000, P<0.05), and ALT and creatine kinase(CK)in 1 case(r=0.964, P<0.05). The ALT, AST and LDH returned to normal soon after the primary diseases were controlled.

CONCLUSIONSevere heart failure, hypoxemia, shock, etc. are the leading primary diseases causing HH. The sharp increase in ALT, AST and LDH is the typical laboratory manifestion in HH after the onset, which may decline to normal shortly after the treatment, sometimes complicated with reversible change in BUN or CK.

Objective:To explore the possible effects of Bushen Huoxue Formula (the kidney tonifying and blood activating prescription) on the proliferation and extracellular matrix synthesis of nucleus pulposus cells by regulating the circ_0036763/miR-583 axis.Methods:Real time fluorescence quantitative polymerase chain reaction (qRT-PCR) was used to detect the expression levels of circ0036763 and miR-583 in normal and intervertebral disc degeneration (IDD) nucleus pulposus cells; IDD nucleus pulposus cells were divided into pcDNA group, pcDNA circ_0036763 group, pcDNA circ_0036763+ mimic NC group, and pcDNA circ_0036763+ miR-583 mimic group. qRT-PCR was used to detect the expression levels of circ_0036763 and miR-583 in nucleus pulposus cells in each group, methyl thiazolyl tetrazolium (MTT) was used to detect cell proliferation (A value), and Western blot was used to detect the expression of proliferating cell nuclear antigen (PCNA), collagen Ⅰ, and collagen Ⅱ proteins in nucleus pulposus cells, The dual luciferase assay reported experimental validation of the targeting relationship between circ_0036763 and miR-583. 27 mice were divided into sham surgery group, IDD group, and kidney tonifying and blood activating formula group. IDD models were established in all groups except for the sham surgery group. After successful modeling, the sham surgery group and IDD group were given physiological saline by gavage, while the kidney tonifying and blood activating formula group was given 1.5 g/ml of kidney tonifying and blood activating formula by gavage for 3 consecutive weeks. QRT-PCR was used to detect the expression levels of circ0036763 and miR-583 in the nucleus pulposus cells of mice in each group, MTT was used to detect cell proliferation, and Western blot was used to detect the expression of PCNA, collagen Ⅰ, and collagen Ⅱ proteins.Results:The expression level of circ_0036763 in IDD nucleus pulposus cells decreased, while the expression level of miR-583 increased (all P<0.05); Overexpression of circ_0036763 can promote proliferation and extracellular matrix synthesis of nucleus pulposus cells (all P<0.05); Circ_0036763 targets miR-583 and upregulates miR-583 reversible overexpression. Circ_0036763 enhances the proliferation and extracellular matrix synthesis ability of IDD nucleus pulposus cells. Compared with the sham surgery group, the IDD group showed an increase in collagen Ⅰ protein expression and miR-583 expression levels (all P<0.05), while the cell A value, PCNA and collagen Ⅱ protein expression, and circ_0036763 expression levels decreased (all P<0.05); Compared with the IDD group, the Kidney Tonifying and Blood Activating Formula group showed a decrease in collagen Ⅰ protein expression and miR-583 expression levels (all P<0.05), while the cell A value, PCNA and collagen Ⅱ protein expression, and circ_0036763 expression levels increased (all P<0.05). Conclusions:The kidney tonifying and blood activating formula (Bushen Huoxue) may induce proliferation and extracellular matrix synthesis of nucleus pulposus cells by regulating the circ_0036763/miR-583 axis.

Objective To evaluate the effect of applying sitting posture corrector on improving reading and writing posture of elementary school students， and provide scientific evidence for prevention and control of myopia in children and adolescents. Methods One elementary school each in urban and suburban areas of Shanghai was selected using a convenience sampling strategy. Furthermore， two classes each in Grade 3 and 4 were selected as the intervention group （282 students were included in the study）， and the other two classes each in Grades 3 and 4 were selected as the control group （294 students were included in the study）. Students in the intervention group used the sitting posture corrector in the classrooms for 4 months （from September 2020 to January 2021）， while those in the control group did not use the sitting posture corrector. Relevant data were collected before and after the intervention through a self-administered questionnaire and visual examination. Statistical analysis was performed using chi-square test and generalized estimating equation. Results Before the intervention， 13.5% （38/282） of students in the intervention group and 12.2% （36/294） in the control group had good reading and writing posture （ χ ² = 0.195， P >0.659）. After the intervention， 18.4% （52/282） of students in the intervention group had good reading and writing posture， which was higher than that （11.2%， 33/294） in the control group （ χ ²=5.957， P =0.015）. Before and after the intervention， there was no significant differences in the prevalence of myopia between students in the intervention and control groups （all P >0.05）. Generalized estimating equation analysis showed that students in the intervention group were 1.502 times more likely to have good reading and writing posture than those in the control group after the intervention （ P =0.043）. Conclusion Applying sitting posture corrector in schools could improve students' reading and writing posture.
