Objective To develop a convolutional neural network （CNN） that can identify isokinetic knee exercises moment of force-time diagrams under different levels of efforts. Methods The 200 healthy young volunteers performed concentric isokinetic right knee flexion-extension reciprocating exercises with maximal effort as well as half the effort at angular velocities of 30°/s and 60°/s twice, respectively, with an interval of 45 min. The moment of force-time diagrams were collected. The 200 subjects were randomly divided into the training set （140 subjects） and the testing set （60 subjects）. The moment of force-time diagrams from subjects in the training set were used to train CNN model, and then the fully trained model was used to predict types of curves from the testing set. Random sampling of subjects along with subsequent development of models were performed 3 times. Results Under the circumstances of isokinetic knee exercises with maximal effort and half the effort, 2 400 moment of force-time diagrams were produced, respectively. Classification accuracy rates of the CNN models after the 3 trainings were 91.11%, 90.49% and 92.08%, respectively, and the average accuracy rate was 91.23%. Conclusion The CNN models developed in this study have a good effect on differentiating isokinetic moment of force-time diagrams of maximal effort exercises from those made with half the effort, which can contribute to identifying levels of efforts exerted by subjects during isokinetic knee exercises.

Objective To investigate the effect of reducing antipsychotic dose on clinical symptoms in patients with stable schizophrenia. Methods Seventy-five patients with stable schizophrenia taking olanzapine or risperidone were enrolled. Patients were randomly divided into dose reduction group (37 cases) and maintenance group (38 cases). The dose of the risperidone or olanzapine was gradually reduced by 50％ in the dose reduction group within six months whereas remained unchanged in the maintenance group. The Positive and Negative Symptom Scale (PANSS), Calgary Depression Scale (CDRS), Personal and Social Performance Scale (PSP), Insight and Treatment Attitude Questionnaire (ITAQ) and Extrapyramidal Side Effects Scale (RSESE) were assessed at baseline, 3 months, 6 months and 12 months. Results There were one and two cases dropped out due to the relapse in dose reduction group and in maintenance group, respectively. The recurrence rates were 2.7％ in dose reduction group and 5.3％ in maintenance group (P<0.05). The interaction effects of PANSS positive symptoms, negative symptoms and general pathological symptoms, ITAQ,RSESE, PSP were significant (P<0.05). The main effect of PANSS negative symptoms and PSP group was significant (P<0.05). Compared with the maintenance group, PANSS negative symptoms of the dose reduction group were significantly lower at 6 and 12 months (P<0.05). PSP scores were significantly higher in the dose reduction group than in maintenance group (P<0.05) at 3, 6 and 12 months. Conclusion Reducing the dose of risperidone or olanzapine slowly in patients with stable schizophrenia within six months reduces negative symptoms and adverse reaction, improves social function without increasing positive symptoms.

Objective To explore social function of long-term hospitalized patients with stable schizophrenia and its influential factors to provide scientific evidence for improving social function in long-term hospitalized patients with schizophrenia. Methods A total of 75 long-term hospitalized patients with stable schizophrenia were enrolled. The Social Functional Rating Scale (SFRS), Positive and Negative Syndrome Scale (PANSS), Insight and Treatment Attitude Questionnaire (ITAQ), Rating Scale for Extrapyramdal Side Effects (RSESE) and MATRICS (Measurement and Treatment Research to Improve Cognition in Schizophrenia) Consensus Cognitive Battery (MCCB) were used to assess social function, clinical symptoms and cognitive function of patients. Bivariate correlation analysis and linear regression were used to examine the correlations between social function and clinical symptoms as well as cognitive function. Results The average score of SFRS was (53.6 ±9.3). Linear regression analysis showed that negative symptom of PANSS (B= 0.322, P=0.009), speed of processing (B=-0.428, P<0.001), working memory (B=-0.191, P=0.020)and RESES (B=0.918, P=0.002) were significantly associated with social function. The Sobel test showed significant indirect effects between negative symptom and social function, which were significantly mediated by working memory (Z=3.367, P<0.001) and speed of processing (Z=1.995, P=0.046). Conclusion Social function of long-term hospitalized patients with stable schizophrenia is influenced by negative symptom, speed of processing, working memory and extrapyramdal side effects. There is a mediating effect between PANSS negative symptoms and SFRS in working memory and processing speed.

OBJECTIVETo investigate the diagnostic value of circulating serum miRNA for multiple myeloma.

METHODSForty blood samples from patients with multiple myeloma were collected from July 2013 to June 2014 in Department of Hematology, Zhongshan Hospital Affiliated to Xiamen University. The real-time quantitative PCR was performed to detect the serum expression levels of miRNAs (miR-29a, miR-155, miR-16 and miR-92a) circulating in the different stages of patients with multiple myeloma and evaluate the diagnostic value for patients with multiple myeloma.

RESULTSThe serum level of miR-29a significantly increased in newly diagnosed patients as compared to healthy donor (P<0.01), serum miR-155 levels were significantly lower as compared with healthy donor(P<0.001); The ratio of miR-29a and miR-155 was an effective biomarker for distinguishing multiple myeloma from healthy donor, their sensitivity and specificity were 80.8% and 83.3% respectively for myeloma diagnosis. the change of miR-29a expression was consistent with the changes of bone marrow plasma cells and M protein levels.

CONCLUSIONThese circulating serum microRNA, such as miR-29a, miR-155 and miR-16, may serve as potential diagnostic biomarkers for multiple myeloma, and the ratio of miR-29a/miR-155 may serve as a most useful biomarker for myeloma diagnosis.

Objective To summarize the treatment principle of acupuncture-moxibustion in treating Bi-impediment syndrome from the application rules of meridians and acupoints in Ming-Qing Dynasties by sorting out and analyzing the Chinese medicine literatures about acupuncture-moxibustion for Bi-impediment syndrome in Ming-Qing Dynasties, for providing literature evidence for basic and clinical research of Bi-impediment syndrome.Method Via electronic retrieval ofZhong Hua Yi Dian (Zhen Jiu Tui Na Lei) (Chinese Medical Encyclopedia,Chapter of Acupuncture-Moxibustion and Tuina), the data related to Bi-impediment syndrome in Ming-Qing Dynasties were extracted to establish a database categorized by meridians and acupoint features in Excel for analysis.Result There were 267 items of records about acupuncture-moxibustion in treating Bi-impediment syndrome in Ming-Qing Dynasties, involving the fourteen ordinary meridians, and 131 acupoints including 5 extra points; the frequency of using the Gallbladder Meridian ranked the top, followed by the Large Intestine Meridian; points from the Bladder Meridian were predominant, followed by the Gallbladder Meridian; there were 28 commonly-used acupoints (frequency>5), which were Quchi (LI 11, 26 times), Huantiao (GB 30, 23 times), Hegu (LI 4, 22 times), Chize (LU 5, 16 times),Yanglingquan (GB 34, 15 times), and Weizhong (BL 40, 14 times). Of the specific acupoint, the five Shu points were most frequently used, with a frequency of 217.Conclusion In the treatment of Bi-impediment syndrome with acupuncture-moxibustion, doctors in Ming and Qing Dynasties selected yang meridians more often than yin meridians, and Gallbladder, Large Intestine and Bladder Meridians had comparatively higher frequencies; regarding the application of acupoints, the specific acupoints were often used, especially the five Shu acupoints. The study results provide reference for acupoint selection in the treatment of Bi-impediment syndrome with acupuncture-moxibustion.

BACKGROUNDGlobally, the proportion of child deaths that occur in the neonatal period remains a high level of 37-41%. Differences of cause in neonate death exist in different regions as well as in different economic development countries. The specific aim of this study was to investigate the causes, characteristics, and differences of death in neonates during hospitalization in the tertiary Neonatal Intensive Care Unit (NICU) of China.

METHODSAll the dead neonates admitted to 26 NICUs were included between January l, 2011, and December 31, 2011. All the data were collected retrospectively from clinical records by a designed questionnaire. Data collected from each NICU were delivered to the leading institution where the results were analyzed.

RESULTSA total of 744 newborns died during the 1-year survey, accounting for 1.2% of all the neonates admitted to 26 NICUs and 37.6% of all the deaths in children under 5 years of age in these hospitals. Preterm neonate death accounted for 59.3% of all the death. The leading causes of death in preterm and term infants were pulmonary disease and infection, respectively. In early neonate period, pulmonary diseases (56.5%) occupied the largest proportion of preterm deaths while infection (27%) and neurologic diseases (22%) were the two main causes of term deaths. In late neonate period, infection was the leading cause of both preterm and term neonate deaths. About two-thirds of neonate death occurred after medical care withdrawal. Of the cases who might survive if receiving continuing treatment, parents' concern about the long-term outcomes was the main reason of medical care withdrawal.

CONCLUSIONSNeonate death still accounts for a high proportion of all the deaths in children under 5 years of age. Our study showed the majority of neonate death occurred in preterm infants. Cause of death varied with the age of death and gestational age. Accurate and prompt evaluation of the long-term outcomes should be carried out to guide the critical decision.

OBJECTIVETo compare the therapeutic effects of peripheral facial paralysis in acute stage by different interventions and explore the better treatments of peripheral facial paralysis.

METHODSOne hundred and thirty one cases of Bell's facial paralysis were randomly divided into three groups. In acupuncture group (44 cases), Dicang (ST 4), Jiache (ST 6), Hegu (LI 4), Yangbai (GB 14) and Taiyang (EX-HN 5), etc. were applied; in electroacupuncture group (45 cases), the selection of acupoints and needling method were same as those in acupuncture group, and the electroacupuncture therapy was applied on Dicang (ST 4), Xiaguan (ST 7), Yangbai (GB 14) and Taiyang (EX-HN 5) in acute stage; in medication and acupuncture group (42 cases), Prednisone and Acyclovir were taken by oral administration, Vitamin B1 and Vitamin B12, were applied by intramuscular injection in acute stage, and acupuncture was applied by the way which was same as that in acupuncture group during quiescent and recovery stages. The curative effects were evaluated by House-Brackmann Grading Scale, and the failed rates were observed by follow-up after one and three months.

RESULTSThe cured and markedly effective rates were 79.6% (35/44), 93.4% (42/45) and 78.6% (33/42) respectively in acupuncture group, electroacupuncture group and medication and acupuncture group, and the result in electroacupuncture group was superior to those in acupuncture group and medication and acupuncture group (P < 0.05). The cured rates above tympanichord were 54.2% (13/24), 85.2% (23/27) and 48.0% (12/25) in acupuncture group, electroacupuncture group and medication and acupuncture group, and the result in electroacupuncture group was superior to those in acupuncture group and medication and acupuncture group (P < 0.01). There was no significant differences of cured rates below tympanichord among three groups (P > 0.05); and the failed rate in electroacupuncture group was much lower than those in acupuncture group and medication and acupuncture group by follow-up after one and three months (all P < 0.01).

CONCLUSIONThe peripheral facial paralysis is effectively treated by electroacupuncture in acute stage, and it suggests that electroacupuncture should be applied early during the acupuncture treatment of peripheral facial paralysis.
