Health science popularization industrialization is a necessary choice for the development of health popularization business.However,in the process of health science popularization industrialization,there exists certain difficulties to balance the contradiction between profitability and public welfare.In theory,the public welfare goal of health science popularization can be realized by industrial profitability means;therefore,the ethical dilemma about it can be solved.In the policy practice,the government may be the main body of the health popularization while profit-making organizations may carry out the health popularization.The government can promote the health popularization industrialization by purchasing health popularization from the relative organizations.

Background:The incidence of chronic constipation is increasing in recent years,which seriously affects the quality of life of patients. Aims:To investigate the therapeutic efficacy of lactulose combined with Bacillus subtilis and Enterococcus faecium preparation on chronic constipation. Methods:A total of 112 patients with chronic constipation from Jan. 2011 to Jan. 2014 at Emeishan Hospital of TCM were enrolled,and were randomly divided into observation group and control group. Patients in both groups accepted the guidance of diet. In addition,patients in control group were orally administrated with lactulose while patients in observation group were orally administrated with lactulose combined with Bacillus subtilis and Enterococcus faecium preparation. After 4 weeks of treatment,therapeutic efficacy in the two groups was compared,patient assessment of constipation quality of life scale(PAC-QOL)was used to evaluate the quality of life. Results:The overall therapeutic efficacy rate in observation group was significantly higher than that in control group (98. 2% vs. 72. 2% ;χ2 = 12. 399,P < 0. 05). Score of every factor and the total score of PAC-QOL were significantly lower after treatment than those before treatment in both groups(P < 0. 05),while physical discomfort score and the total score in observation group were significantly lower than those in control group( P < 0. 05). Conclusions:Lactulose combined with Bacillus subtilis and Enterococcus faecium preparation can effectively improve the symptoms of difficulty in defecation,hard stool,and improve the quality of life in patients with chronic constipation.

Objective To observe the effect of tacrolimus(FK506)in promoting repair of the injured spinal cord pathway after neural stem cell transplantation in rats. Methods A neurysm clip was used to compress the T8 spinal cord segment of SD rats under microscope to establish model of spinal cord injury.The rats were randomly divided into three groups seven days after injury,ie,control group (injection of normal saline at the injury center),transplantation group(injection of neural stem cells,NSCs,at the injury center),FK506 group(injection of NSCs at the injury center plus 7 days of intrapernerve conduction was compared by using the Basso-Beatfle-Bresnahan (BBB) scale,BDA tracing,somatosensory evoked potential(SEP)and motor evoked potentials(MEP)monitoring at 1,2,4 and 8weeks. Results The motor function of the hind limb after injury was recovered in various degrees with time,with the most significant recovery at 4 weeks.The BBB score reached 6,the maximum at 8 weeks.BDA tracing showed that some nerve fibers were found crossing the injured center of the spinal cord one week later in FK506 group and cell transplantation group,that BDA-positive labeled corticospinal tract fibets were seen across the injury site in all groups by the end ofthe eight weeks.In the FKS06 group,the regeneration could be observed even as 1.7 cm away from tlle injury center.SEP latency was significantly shorter in the FK506 group after two weeks(P<0.05)and the MEP latency in the FK506 group was shortened significantly at four weeks compared with the other groups(P<0.05),indicating that the immunosuppressants could promote the recovery of the injured spihal cord,shorten the latency of SEP and MEP，improve SEP at early stage and MEP at late stage．Conclusions Systemic application immuno suppressive agents FK506 plays an important role in neuroprotection and neurotrophy，which promotes the repair of the injured spinal cord after neural stem cell transplantation．

Objective To explore the surgical intervention outcomes of necrotizing enterocolitis (NEC)pa-tients with different extent of the disease.Methods The data of 25 pediatric patients with NEC who were treated with surgical intervention in Shanghai Children′s Hospital from December 201 1 to December 201 5 were retrospectively ana-lyzed.According to the extent of the disease,the patients were divided into 3 groups:focal disease(F),multisegmental disease(M),and pan -involvement(P).The information including operation style,survival rate and time for close osto-my was analyzed.Results There were 1 1 cases with F,8 cases with M,and 6 cases with P.All patients received lapa-rotomy surgery,colostomy,or peritoneal drainage.There were 1 2 patients with very low birth weight,7 patients with low birth weight,6 patients with normal birth weight in this study.There were 1 7 cases with gastrointestinal perforation (9 cases with pneumoperitoneum,8 cases without pneumoperitoneum),8 cases without digestive tract perforation (4 cases without pneumoperitoneum,4 cases with enterostenosis after conservative treatment).In this study,close ostomy was commonly conducted 3 -6 months after the operation,except for 3 cases who received 2 or more times of operation.The survival rate in F group was 1 00.0%(1 1 /1 1 cases),higher than those in the Mgroup with 62.5%(5 /8 cases)and P group with 1 6.7%(1 /6 cases)(χ2 =4.898,1 0.31 2,all P <0.05).However,there was no difference between Mgroup and P group (χ2 =1 .367,P >0.05).Conclusions The extent of disease is correlated to the outcomes of surgical in-tervention,as F had a better outcome than Mand P.Low birth weight is a risk factor for NEC.Protecting the edge of the bowel is a key factor to ensure the survival and improve the quality of life of NEC patients.Close ostomy should be con-sidered when the patients are in a stable condition (liver function and intestinal function recovery,good nutrition condi-tion,etc),and under special circumstances to conduct early or delayed closure of fistula.

Objective To investigate the effect of early application of clean intermittent catheterization(CIC) in infants with neurogenic bladder(NB).Methods Eighty-seven children with NB diagnosed in our urodynamic center were less than 1 year old when they first came to hospital from January 2007 to January 2010, and CIC was carried out at different age.Sixty-four patients were followed up for a long time and divided into early CIC group(less than 1 year old children) and late CIC group(more than 3 years old children) according to the treatment time.Early CIC group included 29 patients [19 boys and 10 girls with the mean age of (7.5 ±2.8) months].And 4 cases were suffering from postoperative spina bifida manifesta;22 cases with spina bifida occulta;2 cases with sacral dysplasia;1 case with meningitis.Late CIC group included 35 patients [20 boys and 15 girls with the mean age of (8.0 ±2.9) months].2 cases were suffering from postoperative spina bifida manifesta;28 cases with spina bifida occulta;4 cases with sacral dysplasia;1 case with postoperative pelvic surgery.Before the treatment, there were no significant differences of the bladder compliance (BC), the maximum cystometric capacity (MCC) and the safety bladder capacity (SBC) between two groups.Urodynamic parameters and complications of 64 patients who were successfully followed up for 6 years were compared.Results After 3 years follow up, BC, SBC and MCC in early CIC group [(8.5 ± 1.9) ml/cmH2O, (140 ±25) ml, (142 ±29) ml]were significantly higher than those of late CIC group [(7.0 ± 2.2) ml/cmH2O, (110 ± 31) ml, (120 ± 28) ml;all P ＜ 0.05].After 6 years follow up, BC, SBC and MCC in early CIC group [(12.0 ±2.5) ml/cmH2O, (210 ±26) ml, (230 ±30) ml] were significantly higher than those of late CIC group [(9.3 ± 2.3) ml/cmH2O, (192 ± 31) ml, (205 ± 35) ml;all P ＜ 0.05], and the vesicoureteral reflux rate [24.1％ (7/29)] in early treatment group was significantly less than that in late treatment group [54.3％ (19/35), P ＜ 0.05].Increases in BUN and serum creatinine were found in 6 cases (20.7％) in early CIC group and 17 cases (48.6％) in late CIC group, the difference was significant (P ＜ 0.05).Conclusion For NB patients, the effect of early CIC is better than that of late CIC.

Objective To enhance awareness of the dangerous of multiple magnets ingestion in children and to explore the optimal treatment of it.Methods The clinical data of 3 cases with multiple magnet ingestion were retrospectively studied based on literature review.Results Ingestion of multiple magnets (range:2-5 magnets) magnets occurred in 3 cases.Age ranged from 1 to 8 years old.Magnet sources included:2 from children's family,1 from their kindergarten.All patients had several bowel perforations(range:2-4).One case was completed by laparoscopic,1 case was converted to open suegery after laparoscopy,1 case was done by open surgery.All cases got complete recovery after surgical treatment,and no complications occurred by follow-up.Conclusions Ingestion of multiple magnets may show minimal initial physical manifestations at beginning but may result in significant complications later.Two or more magnets separated from each other along the gastrointestinal tract can attract each other across bowel walls,with may result in pressure necrosis,bowel perforation,and fistulas formation and even death.Early surgical consultation with an aggressive surgical approach is recommended.Family and society should be aware of the dangers of magnet ingestion.

Objective To explore the clinical results of total ankle replacements with the Scandinavian Total Ankle Replacement (STAR) prosthesis for end-stage ankle arthritis.Methods Data of 73 cases with end-stage ankle arthritis who received Scandinavian total ankle replacement from January 2005 to May 2013 were retrospectively analyzed.They were 34 males and 39 females,with an average age of 59.6 years old (range,37-76 years old),average body mass index (BMI) of 25.3 kg/m2 (range,21.8-28.0 kg/m2).All patients were classified into stage-3 arthritis according to Morrey-Wiedeman.Kofoed,American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot score and visual analog scale (VAS) were used to evaluate the function of foot and ankle.Patients with a hindfoot deformity below 10° were compared with those who above 10°;and patients above 55 years old were compared with those who below it.Results 5 replacement failed (2 liner ruptured and received replacement;2 metal components displaced,1 received TTC fusion and the other underwent revision with inferior tibiofibular joint fusion,the last patient suffered from deep infection and received the STAR removal and secondary fusion) in 73,and the rest were followed up for 12 to 110 months (average,55.2 months).59 patients were satisfied with or without reservations.The satisfaction rate was 80.8％ (59/73).The pre-op values of AOFAS,Kofoed,VAS and range of motion (ROM) were 46.6±3.5,43.0±4.7,8.7±0.7,34.4°±7.1° and the post-op values were 86.6±4.3,82.6±4.6,3.0±1.0,45.1°±8.2° respectively,and all were significantly improved compared with before.The AOFAS,AOFAS Function and ROM values of patients below 55 years old were 86.1±3.8,47.0±2.7,45.7°±7.0°,and the same values of patients above 55 were 86.7±4.6,46.8±3.1,44.9°±8.8°.The AOFAS,AOFAS Function and ROM values of patients with above 10° coronal deformity were 86.1±4.7,47.0±2.7,43.0°±7.7°,and the same values of patients below 10° were 86.8±4.2,46.8±3.1,46.1°±8.2°.There was no difference between the groups.Conclusion The STAR is the preferable surgical treatment option in patients with end-stage ankle arthritis,showing high reliability and effectivity in pain relieving and function improvement.

With thousands of sequenced 16 S rRNA genes available,and advancements in oligonucleotide microarray technology,the detection of microorganisms in microbial communities consisting of hundreds of species may be possible.The existing algorithms developed for sequence-specific probe design are not suitable for applications in large-scale bacteria detection due to the lack of coverage,flexibility and efficiency.Many other strategies developed for group-specific probe design focus on how to find a unique group-specific probe that can specifically detect all target sequences of a group.Unique group-specific probe for each group can not always be found.Hence,it is necessary to design non-unique probes.Each probe can specifically detect target sequences of a different subgroup.Combination of multiple probes can achieve higher coverage.However,it is a time-consuming task to evaluate all possible combinations.A feasible algorithm using relative entropy and genetic algorithm (GA) to design group-specific non-unique probes was presented.

Objective:To provide scientific evidence for infection prevention and control by analyzing the risk factors of surgical site infection, which can move forward the gateway of infection prevention and control.Methods:The surgery-related information of patients admitted to the Department of General Surgery and Department of Orthopedics, People's Hospital of Guangnan Hospital of Yunnan province from November 2016 to August 2019 was retrospectively analyzed. According to whether postoperative surgical site infection occurred, the patients were divided into an infection group and a non-infection group. Logistic regression model was used to analyze the risk factors of surgical site infection.Results:A total of 9 346 patients, consisting of 117 patients in the infection group and 9 229 patients in the non-infection group, were included for final analysis. In the infection group, the incidence of surgical site infection was 1.25%. Multivariate analysis showed that hypoproteinemia ( OR = 2.585), unclean incision ( OR = 3.243 and 5.125), and operation duration more than 3 hours ( OR = 2.315), blood transfusion ( OR = 2.239), drainage tube placement ( OR = 2.133) and indwelling catheter placement ( OR = 1.973) were the independent risk factors for surgical site infection, while prophylactic use of antibiotics was a protective factor ( OR = 0.383). Conclusion:Individual factors, operation-related factors, and treatment-related factors are closely related to the occurrence of surgical site infection. Much attention should be paid to the clinical issues like preoperative hypoproteinemia, perioperative prophylactic use of antibiotics and postoperative drainage tube and indwelling catheter placement.
