Objective: To compare the effect of scalp acupuncture and scalp acupuncture plus acupuncture exercise therapy (AET) on walking ability in children with spastic cerebral palsy (CP). Methods: A total of 60 spastic CP children with gross motor function classification system (GMFCS) grades Ⅰ-Ⅲ were divided into a control group and an observation group by the random number table method, with 30 cases in each group. Both groups were treated with the same conventional rehabilitation and scalp acupuncture therapy for CP. The control group received conventional rehabilitation first and then scalp acupuncture. The observation group received AET, which was to receive the conventional rehabilitation and scalp acupuncture simultaneously. Before and after treatment, the clinical efficacy was evaluated by the modified Ashworth scale (MAS) score, scores of dimensions D and E of the gross motor function measure (GMFM) scale, walking speed, and walking distance. Results: During treatment, there were 2 dropouts in the observation group. After 3 courses of treatment, the MAS scores in both the control group and observation group decreased compared with the same group before treatment (P<0.05), and the scores of dimensions D and E of the GMFM, walking speed, and walking distance were increased (P<0.05); the between-group comparison showed that the MAS score in the observation group was lower than that in the control group (P<0.05), and the scores of dimensions D and E of the GMFM, walking speed, and walking distance in the observation group were higher or longer than those in the control group (P<0.05). Conclusion: W ith the same treatments, scalp acupuncture combined with AET is superior to the conventional scalp acupuncture method in reducing lower-limb muscle tone, improving standing balance ability, and walking stability in children with spastic CP.

Objective To analyze the clinical features of infants infected by respiratory syncytial virus (RSV) or human rhinovirus (HRV) in lower respiratory tract in Suzhou area based on the month age and the month of the year.Methods From January 2013 to December 2015,2 206 nasopharyngeal aspirates specimens were collected from the infants with lower respiratory tract infection.Direct immunofluorescence assay was performed to test RSV.Reverse transcription-polymerase chain reaction(RT-PCR) method was used to test HRV.The medical history was collected and pulmonary function tests were performed in some infants who were infected with RSV and HRV.Results In 2 206 cases,total RSV positive rate was 19.90％ (439/2 206 cases) and simple RSV infection positive was detected in 399 cases.Total HRV positive rate was 14.14％ (312/2 206 cases),in which simple HRV infection positive was detected in 250 cases and the detection rate of RSV was significantly higher than that of HRV(x2 =25.88,P ＜0.05).The incidence rate of wheezing in simple RSV infection was 68.17％ (272/399 cases),which was significantly higher than that of simple HRV infection (42.80％,107/250 cases) (x2 =11.174,P ＜ 0.05).RSV infection was frequent from November to February of the next year in which the detection rate in December was highest with the proportion of 50.00％ (99/198 cases) while the rate in June was only 0.57％ (1/175 cases).The detection rate of HRV was 22.86％ (40/175 cases),20.47％ (35/171 cases) and 20.33％ (25/123 cases) in June,July and September respectively.The detection rate of HRV was lower during December to February of the next year.In January,the detection rate was only 4.68％ (11/235 cases),which was the lowest in the whole year.The detection rates of RSV were 33.33％ (4/12 cases),25.21％ (118/468 cases),23.46％ (84/358 cases) and 23.81％ (60/252 cases) in the age group of 28 d-1 month,＞ 1-2 month,＞ 2-3 month and ＞ 3-4 months respectively.Up to the age of 4 months old,the detection rate decreased gradually,and with the increase of age and the detection rate in ＞ 7-8 month group was only 10.96％ (16/146 cases).The detection rate of HRV was 0 (0/12)and 9.40％ (44/468 cases) in the age group of 28 d1 month,＞ 1-2 month,respectively.After 2 months age old,the detection rate fluctuation ranged from 13.22％ to 16.67％.The incidence rate of severe RSV infection was 12.30％ (54/439 cases) and the incidence rate of severe HRV infection was 5.13％ (16/312 cases).Increased respiratory rate was more common in patients with severe RSV infection while severe HRV infection in infants were accompanied by multiple lobar involvement.After RSV infection,the incidence rate of pulmonary function damage was 89.03％ (276/310 cases).After HRV infection,89.27％ (183/205 cases)of the infants suffered from pulmonary function damage.Both RSV and HRV infection might cause pulmonary function damage.Conclusions RSV and HRV are the major pathogens in infants of Suzhou areas.The incidence of RSV-induced wheezing is significantly higher than that of HRV.RSV is detected positive mainly in winter and early spring and the infants within 4-month old are susceptible population.HRV is detected positive mainly in June,July and September and the infants older than 2 months are susceptible population.The incidence of severe RSV infection is significantly higher than that of HRV.Severe RSV infection may cause increased respiratory rate and severe HRV infection mainly cause multiple lobar involvement.RSV and HRV infection may cause pulmonary function damage.

ObjectiveTo investigate the association of high-density lipoprotein cholesterol (HDL-C) with the prognosis of patients with alcohol-related hepatocellular carcinoma (HCC) after radical treatment. MethodsA retrospective analysis was performed for the clinical data of 43 patients with alcohol-related HCC who were admitted to The Fifth Medical Center of Chinese PLA General Hospital and underwent radical treatment from January 2008 to July 2015, and according to HDL-C level, the patients were divided into normal group with 26 patients and abnormal group with 17 patients. The two groups were compared in terms of basic information, laboratory markers, imaging indices, Barcelona Clinic Liver Cancer tumor stage, and Child-Pugh class of liver function. The t-test test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups. The Kaplan-Meier method was used to plot survival curves and the log-rank test was used for comparison between groups. Univariate and multivariate Cox proportional hazards models were used to analyze independent risk factors for prognosis. ResultsThere was a significant difference in prealbumin between the two groups (162.38±60.86 mg/L vs 120.06±64.08 mg/L, t=2.184, P=0.035). Number of tumors (hazard ratio ［HR］=2.839, 95%confidence interval ［CI］: 1.120~7.200,P=0.028), tumor size (HR=2.634, 95%CI: 1.062~6.529,P=0037), and HDL-C level (HR=2.400, 95%CI: 1.040~5.537,P=0.040) were independent risk factors for the overall survival of patients with alcohol-related HCC. There were significant differences in 1-, 3-, and 5-year cumulative survival rates between the normal group and the abnormal group (88.5%/72.4%/55.7% vs 70.6%/43.7%/17.5%, χ2=5.881, P=0.015). ConclusionThe reduction in HDL-C level might indicate poor prognosis of patients with alcohol-related HCC.

Objective To investigate the effect of circular RNA hsa_circ_0001922 on the proliferation, migration and invasion of prostate cancer cell PC-3 and its underlying molecular mechanism. Methods qRT-PCR and RNA FISH were used to detect the expression level and localization of hsa_circ_0001922 in PC-3 cells respectively. After hsa_circ_0001922 was targeted inhibited, clone formation, Transwell assay and scratch assay were used to detect the proliferation, migration and invasion abilities of PC-3 cells. qRT-PCR and Western blot were used to detect the expression levels of EMT pathway-related molecules after inhibiting hsa_circ_0001922. Results The expression of circular RNA hsa_circ_0001922 was increased in PC-3 cells (P < 0.01) and it existed in the cytoplasm and nucleus. The invasion, migration and invasion abilities were significantly weakened (P < 0.05) after inhibiting hsa_circ_0001922; the expression of E-cadherin mRNA increased (P < 0.05) while the mRNA level of Vimentin decreased (P < 0.05). The results of Western blot were consistent with the above (both P < 0.05). Conclusion The circular RNA hsa_circ_0001922 may promote the proliferation, migration and invasion of PC-3 cells through the EMT pathway.

miR-135 is a highly conserved miRNA in mammals and includes miR-135a and miR-135b.Recent studies have shown that miR-135b is a key regulatory factor in cardio-cerebrovascular diseases.It is involved in regulating the pathological process of myocardial infarction,myocardial ischemia/reperfusion injury,cardiac hypertrophy,atrial fibrillation,diabetic cardiomyopathy,atherosclerosis,pulmonary hyperten-sion,cerebral ischemia/reperfusion injury,Parkinson's disease,and Alzheimer's disease.Obviously,miR-135b is an emerging player in cardio-cerebrovascular diseases and is expected to be an important target for the treatment of cardio-cerebrovascular diseases.However,the crucial role of miR-135b in cardio-cerebrovascular diseases and its underlying mechanism of action has not been reviewed.Therefore,in this review,we aimed to comprehensively summarize the role of miR-135b and the signaling pathway mediated by miR-135b in cardio-cerebrovascular diseases.Drugs targeting miR-135b for the treatment of diseases and related patents,highlighting the importance of this target and its utility as a therapeutic target for cardio-cerebrovascular diseases,have been discussed.

Objective To study the epidemiological and clinical features of viral pathogen of acute respiratory tract infection(ARTI)in children in Suzhou. To provide the evidence-based medicine for early warning,diagnosis and treatment of respiratory tract infection in children. Methods The study population comprised of all the children ranging from 28 days to 15 years old with ARTI admitted to Department of Respiration,the Childrenˊs Hospital Affiliated to Soo-chow University,between January 2006 and December 2015. The study cases were divided into 4 age groups based on ages(28 days to <1 year old,1- <3 years old,3- <5 years old and ≥5 years old). The nasopharyngeal aspirates and medical history were obtained by qualified medical personnel. Seven kinds of common respiratory virus were detec-ted by using the direct immunofluorescence. Mycoplasma pneumonia(MP),chlamydia pneumonia(CP)and human bo-cavirus(hBoV)were detected by adopting fluorescence quantitative PCR. Human rhinovirus(HRV)and human metap-neumovirus(hMPV)were detected by means of reverse transcriptionpolymerase chain reaction( RT -PCR). Sputum was cultured for bacteria. Results In 21 624 cases,17 618 cases were detected,and the positive detection rate of virus was 30. 74%(5 416 cases). The highest detection rate of virus was 44. 25%(881/1 991 cases)in 2011 in the 10 years. There were 3 317 cases of single virus pathogen infection,accounting for 18. 83%. Among them,respiratory syn-cytial virus(RSV)was the first with 9. 42%(1 660/17 618 cases),followed by HRV(5. 17%,278/5 372 cases), hBoV(3. 12%,351/11 263 cases),Pinf 3(2. 17%,383/17 618 cases),and the lowest rate was Pinf 2 with 0. 05%(8/17 618 cases). There were 2 099 cases of overlap infection,accounting for 11. 91%. The virus combined with bacte-rial infection accounted for 7. 86%(1 384/17 618 cases),which had the most positive cases. With the increase of age, the single virus pathogen infection rate gradually dropped. The highest detection rate was 22. 82%(1 976/8 656 cases) in the group between 28 days and <1 year old,and the lowest detection rate was 7. 81%(159/2 035 cases)of children over 5 years of age. The virus positive rate of the four seasons was 18. 28%(833/4 556 cases),13. 86%(625/4 508 cases),5. 91%(684/4 298 cases),27. 68%(1 178/4 256 cases),respectively,and detection rate in winter was the highest,and the least in summer. In the single virus infection,bronchiolitis had the highest percentage(36. 32%,25/69 cases),and the least rate was 5. 83%(63/1 080 cases)of lobar pneumonia. Conclusions Monitored for 10 years of the virus respiratory infection in Suzhou area,RSV,HRV and hBoV turned out to play an important role in respiratory tract infection in children. The children less than 3 years old are the most susceptible to virus infection. The epidemic season of each virus is different and characteristic.
