Objective To discuss the etiology and clinical characteristics of human rhinovirus (HRV) as pathogen of central nervous system infection .Methods Two hundred and five cerebrospinal fluid (CSF) specimens were collected from children with fever and convulsions who were admitted to the pediatric intensive care unit with suspicion of central nervous system infection from June 2011 to December 2012 .Genome Lab Genetic Analysis System (GeXP) was applied to detect HRV from CSF .Specimens with positive results were amplified by nested reverse transcription‐polymerase chain reaction and followed by gene sequencing . Clinical data of HRV positive cases were analyzed . Results Of the 205 CSF specimens ,7 samples were positive for HRV ,which were composed of 2 HRV‐A ,1 HRV‐B and 4 HRV‐C (including 1 HRV‐Ca) .There were 6 boys and 1 girl among the 7 positive cases for HRV .Six children were less than 3 years old ,except one was 9 years old .The onset time was mainly concentrated between September and October . The main clinical manifestations were fever and convulsions . The clinical diagnosis before the pathogen confirmation included viral encephalitis ,epilepsy ,febrile convulsion ,benign infantile convulsions with mild gastroenteritis (CwG ) and hand‐foot‐and‐mouth disease ( HFMD ) . Although the disease severity of the 7 cases varied ,all ended with favorable prognosis .Conclusions HRV is one of pathogens of viral central nervous system infection .All types of HRV can cause central nervous system infection ,among which HRV‐C accounts for the majority .The clinical manifestations of HRV central nervous system infection could mimic febrile convulsion ,CwG and HFMD .

Objective To discuss the significance of different types of human rhinovirus (HRV) as pathogen and the clinical features of different types of HRV in pediatric intensive care unit(PICU).Methods Eight hundred and fifty-two nasopharyngeal aspirates specimen (NPA) were collected from children who were admitted to PICU,the Second Affiliated Hospital of Shantou University Medical College from November 2010 to October 2015 and were tested by using nested reverse transcription-polymerase chain reaction (RT-PCR).Gene fragments for VP4/VP2 capsid protein amplified from HRV positive specimens were sequenced for HRV genotype confirmation.Then clinical characteristics of these HRV positive cases were analyzed.Results Among these 852 specimens tested,214 (25.12％) were HRV positive,including 95 samples(44.39％) positive for HRV-A,17 samples (7.94％) for HRV-B,and 55 samples(25.70％)for HRV-C determined by sequence analysis;while the species of 47 samples (21.96％) of the total were unclassified clearly.HRV-A,HRV-B,HRV-C co-infection with other respiratory viruses accounted for 33.68％ (32/95 cases),29.41％ (5/17 cases),and 29.09％ (16/55 cases),respectively.The clinical characteristics of children infected with HRV-A,HRV-B,HRV-C were similar,and wheezing and polypnea were more common with HRV-C infections than HRV-A and HRV-B infections.The severity among children positive for different groups HRV showed no significant difference (H =0.631,P ＞ 0.05),as well as that between children co-infected with HRV and other viruses and those infected with HRV only (H =0.886,P ＞ 0.05).Conclusions Different types of HRV were major causes of infectious disease in pediatric critical disease.The clinical characteristics of children infected with HRV-A,HRV-B,HRV-C were similar.Wheezing and polypnea were more common with HRV-C infections than HRV-A and HRV-B infections.

Objective To investigate the correlation between fatigue and coping strategies among peritoneal dialysis patients,to improve their health consciousness and reduce the fatigue.Methods A total 107 patients were surveyed with general data questionnaire,Multidimensional Fatigue Symptom Inventory-Short Form( MFSI-SF) ,and Medical Coping Modes Questionnaire,MCMQ.Results The score of fatigue was (83.32 ±1.54) points,which indicated the fatigue remained in high level.Scores from high to low were dialysis≥5years,dialysis<1year and 1year≤dialysis<5years.Patients mainly took the coping style with positive face.Pearson correlation analysis showed that fatigue was negatively correlated withface(r=-0.300,P<0.05),while it was positively correlated with withdrawand yield(r=0.227,0.300,all P<0.05).Conclusion Patiens should be encouraged to actively face the disease,pay more attention to their own state of dialysis and improve the effect of drain,reduce fatigue,then to reply for both mind and body health.

Objective To compare the setup errors of the negative pressure vacuum air cushion (vacuum bag) and the Orfit body foam fixator (Orfit frame) in radiotherapy for cervical cancer.Methods A total of 40 patients receiving three-dimensional radiotherapy for cervical cancer were enrolled in this study and equally and randomly divided into vacuum bag group and Orfit frame group.And the two groups were divided into Orfit-1 group, Orfit-2 group, vacuum-1 group, and vacuum-2 group according to the treatment course.The Orfit-1 group and vacuum-1 group were the data in the first 12 treatments, while the Orfit-2 group and vacuum-2 group were the data in the following 13 treatments.A cone-beam computed tomography scan was performed before each treatment to analyze setup error and then the body position was corrected to start the treatment.Comparison of continuous data between groups was made by paired t-test, while comparison of categorical data was made by chi-square test.Results There was a significant difference in the setup error in y-axis direction between the Orfit-1 group and the Orfit-2 group (P=0.003) and the setup error in r-axis direction between the vacuum-1 group and the vacuum-2 group (P=0.013).There were no significant differences in the setup errors in four directions (x-axis, y-axis, z-axis, and r-axis) between the Orfit-1 group and the vacuum-1 group (P>0.05).There were significant differences in the setup errors in y-axis and z-axis directions between the Orfit-2 group and the vacuum-2 group (P=0.007;P=0.001).Conclusions The Orfit frame and the vacuum bag have their own advantages and disadvantages in the fixation of body position in radiotherapy for cervical cancer.The setup error can be improved by long vacuum bags, ultrasound bladder capacity scanner, image-guided radiotherapy, or sectional radiotherapy plan.

Background and purpose: With the application of laparoscopy in the liver surgery increasingly widely used, the safety and feasibility of laparoscopic liver resection is gaining recognition gradually. This study aimed to explore the laparoscopic liver resection for the tumor and the feasibility of open liver tumor resection and clinical curative effect. Methods: We retrospectively analysed the clinical data from 37 cases of laparoscopic hepatectomy and 74 patients with open liver resection from Mar. 2015 to Mar. 2016. Measurement data by covariance analysis were obtained, and comparison between groups were made using independent sample with Wilcoxon rank test and statistical value of Z. We collected data including operation time, intra-operative blood loss, post-operative recovery time of gastrointestinal tract, surgical drainage tube after extubation time, length of hospital stay, postoperative complications, hospitalization expenses and other clinical data. Laparoscopic group had 20 males and 17 female aged 18 to 76 (median age 55). Open group had 42 males and 32 females aged 26 to 74 (median age 54). The hepatectomy included ultrasonic knife + unipolar electric coagulation, combined with laparoscopic incision suture. Surgery procedures included 13 cases of local excision in laparoscopic group and 24 cases of liver segment or lobe anatomical resection. Open group had 33 cases of local excision and 41 cases of liver segment or lobe anatomical resection. Results: The average duration of laparoscopic hepatectomy was 149 min (40-204 min). The average duration of open hepatectomy was 142 min (45-190 min). The average intra-operative blood loss was 220 mL (30-570 mL) in laparoscopic group and 360 mL (90-970 mL) in open group. The average length of hospital stay was 4.9 d (3-6 d) in laparoscopic group and 6.8 d (5-9 d) in open group. Gastrointestinal average recovery time was 1.1 days in laparoscopic group and 2.3 days in open group. The average hospitalization expenses were 38760 yuan in laparoscopic group and 39145 yuan in open group. Conclusion:Laparoscopic hepatectomy is a safe, effective and minimally invasive surgery, can be safely used in local, liver segment and half liver resection, worthy of promotion.

Objective To investigate the association between hepatitis B virus (HBV)genotype, the mutations in HBV basic core gene promoter(BCP), pre C/C gene region and treatment response to interferon (IFN)α-1b. Methods Hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB) patients were treated with IFNα-Ib for 6 months and were followed up for 6 months after the end of treatment. Restriction Fragment Length Polymorphism (RFLP) was used for determining HBV genotype. HBV DNA was amplified by polymerase chain reaction (PCR) and analyzed for BCP and pre C/C gene region by sequencing. Measurement data were compared using t test and analysis of variance. Enumeration data were compared using chi-square test, Fisher exact probability test.Logistic regression analysis was utilized for multi-factor analysis. Results There were 39 patients who completed the treatment and follow up in this study. At the end of treatment, 16(41.0%) patients showed response to the IFNα-lb treatment. At the end of follow-up, four out of 16 patients who achieved on treatment response relapsed. Among 3a patients, 29 (74.4 %) were infected with genotype B and 10 (25. 6%) with genotype C. The treatment response rates were not significant different between the groups with different genotypes. The double mutation pattern (T1762/A1764) was found in eight (20. 5%) patients. The response rates to IFNα-lb treatment were not significant different between the group with and without double mutation pattern. A1896 mutation was detected in eight patients at baseline. Three of them became HBeAg negative at the end of treatment and returned to HBeAg positive during follow-up. The non-lyphocyte epitope mutations, L60V and I97L, were found in 15 patients (38. 5%) and 14 patients (35.9%), respectively. At the end of follow-up, the patients with 60V had a significantly lower HBeAg seroconversion rate and HBV DNA undetectable rate compared to the patients with 60L (Fisher exact probability test; P = 0.0126 and 0.0069,respectively). The HBV DNA undetectable rates in the patients with 97I were significantly lower than those in patients with 97L both at the end of treatment and the end of follow-up (Fisher exact probability test; P= 0.0484 and 0. 0024, respectively). Logistic regression analysis results showed that there was no association between the above viral mutations and the treatment response to IFNαlb. Conclusions There is no association between HBV genotype, BCP double mutation pattern and IFN-α treatment response. The non-lyphocyte epitope mutations, L60V and I97L, may have impact on IFN-α treatment response.

INTRODUCTION: Teleophthalmology may assist the healthcare sector in adapting to limitations imposed on clinical practice by a viral pandemic. A scoping review is performed in this study to assess the current applications of teleophthalmology for its suitability to diagnose, monitor or manage ophthalmological conditions with accuracy. METHODS: A search of PubMed was conducted for teleophthalmology-related articles published from 1 January 2018 to 4 May 2020. Only articles that focused on the use of teleophthalmology in terms of diagnosis and management, as well as its benefits and detriments, were included. The Mixed Methods Appraisal Tool (MMAT) was used to assess the quality of the included articles. RESULTS: A total of 38 articles were assessed at the full-text level. There were 2 qualitative studies and 1 quantitative randomised controlled trial, while the majority were either quantitative descriptive studies (19, 50.0%) or quantitative non-randomised studies (16, 42.1%). Overall, 8 studies described reducing manpower requirements, 4 described reducing direct patient-doctor contact, 17 described storage of medical imaging and clinical data, and 9 described real-time teleconferencing. The MMAT analysis revealed limitations in appropriate sampling strategy in both quantitative non-randomised studies (9 of 16, 56.3%) and quantitative descriptive studies (9 of 19, 47.4%). Cost-effectiveness of teleophthalmology was not performed in any included study. CONCLUSION This current review of the various aspects of teleophthalmology describes how it may potentially assist the healthcare sector to cope with the limitations imposed by a viral pandemic through technology. Further research is required to evaluate the cost-effectiveness of the various strategies.

Objective:To understand the current situation of postpartum maternal perceived spouse support for breastfeeding, and explore its mediating role in the spouse support for breastfeeding and maternal breastfeeding self-efficacy.Methods:From October 2021 to October 2022, convenience sampling was used to select 602 postpartum women (42 days postpartum) and their spouses who underwent follow-up visits at Obstetric Clinics in four ClassⅢ hospitals in Shanghai as the research subject. A questionnaire survey was conducted using the General Information Questionnaire, Partner Breastfeeding Influence Scale (PBIS) , and Breastfeeding Self-efficacy Scale Short Form (BSES-SF) .Results:The PBIS score of 602 postpartum women was (121.07±25.41) , and the PBIS score of 602 maternal spouses was (134.37±18.94) . Pearson correlation analysis results showed that maternal perceived spouse support has a positive correlation with spouse support ( P<0.01) , and a positive correlation with maternal self-efficacy in breastfeeding ( P<0.01) ; spouse support was positively correlated with maternal self-efficacy in breastfeeding ( P<0.01) . The mediating effect analysis that maternal perceived spouse support played a complete mediating role between spouse support and maternal self-efficacy in breastfeeding. Conclusions:There are both connections and differences between maternal perceived spouse support and spouse support, and the positive promoting effect of spouse support on maternal self-efficacy in breastfeeding can be completely mediated by maternal perception. Medical and nursing staff should pay attention to the assessment of maternal perceived spouse support and guide spouse breastfeeding support behavior based on maternal needs and experiences of spouse support, so as to improve breastfeeding outcomes.

Objective To discuss the change trends of pathogen of severe hand,foot and mouth dis-ease(HFMD) in Chaoshan area during 2011 to 2015. Methods All 1410 throat swabs of cases who were diagnosed as HFMD were collected from children hospitalized in our hospital during May 2011 to August 2015. Enterovirus were detected by nest RT-PCR,and the results of these positive cases diagnosed as severe HFMD were analyzed. Results (1) There were 216 positive cases(67. 29％,216/321) diagnosed as severe HFMD,including 53. 70％ ( 116/216 ) enterovirus 71 ( EV71 ), 19. 91％ ( 43/216 ) coxsackievirus A16 (CA16),12. 04％(26/216) CA6,8. 80％(19/216) CA10,3. 24％(7/216) CA4,0. 93％(2/216) coxsack-ievirus B5, 0. 46％ ( 1/216 ) enteric cytopathogenic human orphan virus and 0. 93％ ( 2/216 ) unclassified samples were unclassified to species. (2) Five cases of critical HFMD were all caused by EV71. (3) The EV71 positive samples were given priority to severe cases ( 51. 79％,116/224 ) and the non EV71 positive samples were given priority to mild cases ( 82. 08％, 458/558 ) , the difference was statistically significant (χ2 =91. 68,P<0. 001). (4) The change trends of severe HFMD year by year were consistent with the change trends of EV71 composition,and were highly correlated(Rs=0. 9,P=0. 037). (5) Severe HFMD caused by non EV71 virus gradually increased. Conclusion Severe HFMD in Chaoshan area during 2011 to 2015 were mainly caused by EV71,non EV71 viruses including CA16,CA6,CA10,CA4,coxsackievirus B5, enteric cytopathogenic human orphan virus 6 could also develop to severe HFMD. The composition ratio of severe HFMD increased accordingly in the year of EV71 as the dominant pathogen. The proportion of severe HFMD caused by non EV71 virus gradually increased after 2013 year.
