In this study the nutritive value of 4 kinds of weaning foods containing soyflour were measured by chemical and animals experiments. The 4 experimental weaning foods were:1.This formula was developed by the Institute of Health collaborating the First Food Factory of Beijing. It was produced by the Factory and the trade name is "Baobao Le" The soybean was processed by the infra-red light.2.This formula was recommended by UNICEF (Formula No. 5). Soybean flour was treatded with the extruded method.3.This formula was the same as No. 2 (UNICEF Formula No. 5). In which the soybean was wet-heat treated. No. 2 and 3 samples were produced by Wu Xi Light Industry College.4.This formula was developed by the Institute of Shanghai Food Industry as formula D. Puffed soybean flour was used.The 2 control foods were:5.This formula was based on formula "5410". The sample was made by the First Food Factory of Beijing (trade name, "Nutritive Baby Powder").6.Infant Milk Powder, produced by the Child Milk Factory of Shuang Cheng Xian, Hei Long Jiang Province, cow's milk powder was used as the main source of protein. The protein content of the products were:No. 1 and 4, 19.0%, equal to the protein requirement for weaning foods; No.2 and 3, 15.8%, lower than No.1 and 4; Infant Milk Powder, 15.1%; Nutritive Baby Powder, 17.0%.From the results of the animal experiment on weaning rats with respect to growth, after 9 weeks of feeding, the average body weight of control group 5 and 6 increased by 185.8 and 180.5g respectively, which were significantly higher than 146.7 and 150.4g of the experimental groups No. 1 and 4. While the increased body weight of No. 1 and 4 were higher than group 2 and 3 (79.8g and 113.1g respectively). The increase of body lengths were of the same order of the 6 groups as that in body weight.Blood hemoglobin values were all normal (control groups 13.4 and 13.9g per 100 ml; experimental groups 13.9, 14.2, 13.0 and 13.0g).The weight of pancreas in the 4 experimental groups were all normal. It showed that the activity of trypsin inhibitor had been destroyed. Weights of thyroid of the rats were all within the normal range except group 1,2,3, which were a little bit heavier. Potassium iodide was.added into formula 1,2 and 3, to prevent hyperthyroidism but since potassium iodide is easily to evaporate, so it would be perferable to use potassium iodate instead.The above results indicated that the growth promoting effect of the 4 weaning foods is lower than the two baby powder, but they are good weaning foods for baby after six months. "Baobao Le" and formula No 6 are much better.

Objective To understand the prevalence of unsafe riding practice among electric bicycle riders,and to provide scientific basis for intervention strategies in Ma'anshan city of Anhui Province.Methods Observational method was used to observe electric bicycle riders' behavior of running red light,wearing a helmet,and manned act.The radar speed measuring instrument was used to measure the speed of electric bicycle.Results The rate of electric bicycle riders' running red light was 13.09％ (1 285/9 815),helmet wearing rate was 5.90％ (1 510/25 576),and manned rate was 20.28％ (5 187/25 576).The average speed was 24 ki/h,and the electric bicycles whose speed were ＞ 20 km/h accounted for 74.60％.There were significant differences in the running red light rate,helmet wearing rate and the average speed of travel among different time periods and dates (all P ＜ 0.05).More running the red light occurred during 13:30-14:30 and 15:00-16:00.Less helmet wearing occurred during 10:00-11:00 and 08:30-09:30.The periods with highest average speed were at07:00-08:00,08:30-09:30,11:30-12:30,and 13:30-14:30,which was 24 km/h.The helmet wearing rate of females (6.54％) was higher than that of males(5.46％),the men's average speed (24 km/h) was higher than women's (23 ki/h),and the differences were both statistically significant(all P ＜ 0.001).Conclusion The electric bicycle riders in Ma'anshan city of Anhui Province have the dangerous behavior of running red lights,not wearing a helmet,manned act and speeding.Targeted interventions should be taken to reduce the occurrence of related risk behaviors.

Objective:To explore the effects of ventilator parameters on the compliances of chest and lung,and arterial blood gas indicators of patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD)when biphasic positive airway pressure(BiPAP)ventilation treated AECOPD patients at acute exacerbation period.Method:A total of 78 AECOPD patients who underwent non-invasive ventilation treatment by using BiPAP ventilators in Xinjiang Cardiovascular and Cerebrovascular Hospital from April 2020 to April 2021 were selected.The common range of inspiratory positive airway pressure(IPAP)was 10-25 cmH2O.Based on the specific situation and adjustment of clinical needs of patients,this study set"<15 cmH2O"as the low IPAP group(n=34),and set"≥15 cmH2O"as the high IPAP group(n=44)to analyze the correlation between IPAP of BiPAP ventilator parameters and the therapeutic effects,chest lung compliances and arterial blood gas indicators of patients.Results:The rate of therapeutic effect of patients in the high IPAP group was 93.48%,which was significantly higher than 71.88%of the low IPAP group,and the difference between the two groups was statistically significant(x2=6.766,P<0.05).Before treatment,there were no statistically significant differences in indicators included chest compliance(CTh),lung compliance(CL)and total compliance(Ct)between the two groups(P>0.05).After treatment,the Ct,CL and CTh of patients in the high IPAP group were significantly higher than those in the low IPAP group,and the differences between the two groups were statistically significant(t=2.508,2.027,2.185,P<0.05),respectively.There was no statistically significant difference in arterial oxygen partial pressure(PaO2)value between the two groups before used mechanical ventilation(P>0.05).The PaO2 values of patients at 2,4,6 and 8h of using mechanical ventilation in the high IPAP group were significantly higher than those in the low IPAP group,and the differences between different groups were statistically significant(t=8.531,5.296,3.264,4.623,P<0.05),respectively.Both two groups of patients showed a significant increase in inflammatory mediators such as matrix metalloproteinase-9(MMP-9)and interleukin-8(IL-8)during occurring disease.After treatment,the levels of the two mediators decreased,and the high IPAP group was significantly lower than that of low IPAP group(t=2.251,5.484,P<0.05),respectively.The incidence of abdominal distension in patients of high IPAP group was 20.45%,which was significantly higher than 5.88%of low IPAP group,and the difference between groups was statistically significant(x2=3.623,P<0.05).Conclusion:The IPAP of BiPAP ventilator parameters has effect on chest lung compliance,arterial blood gas analysis and inflammatory indicators in AECOPD patients.High IPAP can improve therapeutic effect,and improve chest lung compliance and arterial blood gas analysis,but can easily cause adverse reactions such as abdominal distension.

Objective To study the curative efficacy and safety of single-unit umbilical cord blood transplantation (sUCBT) for malignant hematologic diseases,which is provided by China's public cord blood bank.Methods We retrospectively analyzed 409 cases of malignant hematologic diseases who accepted myeloablative single-unit unrelated donor UCBT without ATG at our center between May 2008 and December 2016.A comparative analysis was made on the total nuclear cells (TNC) of the umbilical cord blood before freezing and after thawing,the cells of CD34+,the recovery rate of cells and the clinical effect of UCBT.Result 409 units of umbilical cord blood used in UCBT respectively came from eight China's public cord blood banks.The average TNC of 409 units of umbilical cord blood before freezing and after the tubular recovery were respectively 18.5 × 108 and 16.34 × 108 (p =0.000).The average recovery rate of the tubular recovery was 88.5％,and there was significant difference among cord blood banks (P =0.000).The average TNC of umbilical cord blood before freezing and transfusion were respectively 18.5 × 108 and 15.86 × 108 (p =0.000).The average recovery rate of umbilical cord blood transfusion was 85.9％,with the difference being significant among cord blood banks (P =0.000).The average number of CD34+ cells before freezing and after the tubular recovery was 11.18 × 106and 8.68 × 106 (p =0.000).The average recovery rate of CD34+ cells after the tubular recovery was 80.75 ％,with the difference being significant among the cord blood banks (P =0.000).At 42nd day after UCBT,the cumulative incidence of neutrophil engraftment was 95.4％,and the median time of the engraftment was 17 days (11-38 days).The cumulative incidence of platelet engraftment at 120th day was 84.6％,and the median time of the engraftment was 36 days (14-93 days).The cumulative incidence of erythrocyte engraftment at 60th day was 92％,and the median time of engraftment was 22 days (9d-60 days).After the umbilical cord blood provided by each bank was used in UCBT,it got the difference in cumulative incidence of engraftment.The P values for cumulative incidence of neutrophil,platelet and erythrocyte engraftment were respectively 0.004,0.01 and 0.000 2,with the differences being statistically significant.At 100th day after UCBT,the cumulative incidence of Ⅱ-Ⅳ and Ⅲ-Ⅳ degrees of acute graft-versus-host disease (aGVHD) was respectively 28.63％ and 15.7％.After umbilical cord blood provided by each bank was used in UCBT,it got the difference in cumulative incidence of aGVHD.There was no significant difference between Ⅱ-Ⅳ and Ⅲ-Ⅳ degrees (P =0.809 and 0.68 respectively).At 3rd year after UCBT,the cumulative incidence of relapse was 15.89％.After umbilical cord blood provided by each bank was used in UCBT,there was no significant difference in the cumulative incidence of relapse (P =0.898).At 3rd year after UCBT,the overall survival (OS) rate and disease free survival (DFS) rate were respectively 66.7％ and 59％.After umbilical cord blood provided by each bank was used in UCBT,it got the difference in OS and DFS.There was no significant difference in OS and DFS (P =0.566 and 0.703 respectively).At 3rd year after sUCBT,the rate of graft-versus-host diseases/relapse-free survival (GRFS) was 54.3％.After umbilical cord blood provided by each bank was used in UCBT,there was no significant difference in the rate of GRFS (P =0.449).Conclusion The umbilical cord blood provided by China's public cord blood bank was used in UCBT.It has a high safety and good efficacy in treating malignant hematologic diseases.But it needs to set up the standardized and normalized quality-control system of umbilical cord blood for China's public cord blood bank.

Objective:To study the clinical characteristics and death risk factors of the patients with fall-related injuries in parts of Kashgar Prefecture during 2019-2020.Methods:The clinical data were retrospectively analyzed of the 894 patients with fall-related injuries who had been admitted to Department of Trauma Center, The First People's Hospital of Kashgar Prefecture, Xinjiang Uygur Autonomous Region from January 2019 to December 2020. Recorded were the patient's gender, age, location of fall, month of fall, fall height, major injury site, injury severity score (ISS) and Glasgow score (GCS). The clinical characteristics and death risk factors of the fall patients were analyzed.Results:Of the 894 patients, 72.3%(646/894) were male and 86.9%(777/894) fell from a height from 1 to 6 meters. Their ages ranged mainly from 15 to 59 years old (74.3%, 664/894). Home was the most frequent site for falls (60.2%, 538/894) and the patients who fell in summer months (from June to August) were the most (32.3%, 289/894). Twenty-one patients (2.3%, 21/894) died. There were significant differences in the major injury site, blood transfusion, ISS score and GCS score between the dead and survival patients ( P<0.05). The multivariate logistic regression analysis showed that the injury to the head, face and neck [ OR=10.936, 95% CI: 1.177 to 101.627, P=0.035] and GCS score ≤12 [ OR=5.640, 95% CI: 2.658 to 11.968, P< 0.001] were the death risk factors for the patients with fall-related injuries in parts of Kashgar Prefecture during 2019-2020. Conclusions:In the patients with fall-related injuries in parts of Kashgar Prefecture during 2019-2020, males aged from 15 to 59 years old were the high-risk group of falls. Months with a high incidence of falls were from June to August. The fall patients with injuries to the head, face and neck and with a GCS score of ≤12 were at a high risk of death.

Facial paralysis causes both physical pain and psychological distress to patients. It is difficult for a patient with facial paralysis to engage with a normal social life and at work. Progresses have been made in recent years in the treatment of facial paralysis. More attentions have been caught by masseteric to facial nerve transposition, which has advantages of adjacency in location, abundancy in nerve supply and reliability in the outcome and now has deemed an important option of facial reanimation. It has not been long since the application of the technique of masseteric to facial nerve transposition in China, therefore it still lacks a universal guidance on practice. In order to achieve the aim of better quality control and popularisation of the technique, hereby a consensus with suggestions on facial reanimation with masseteric to facial nerve transposition is proposed as the reference for surgeons specialised in facial reanimation. This consensus is proposed, discussed and drafted by experts from plastic and reconstructive surgery, oral and maxillofacial surgery, head and neck surgery and neurosurgery.

Objective To comprehensively analyze the reported preparation methods for animal models of perimenopausal syndrome (PS), to compare the advantages and disadvantages of various preparation elements and detection indexes, so as to provide useful references for the optimization of the relevant animal models as well as the standardization of their application in the efficacy evaluation of new drugs.MethodsIn this paper, literature research methods were applied using "perimenopausal syndrome" as the subject term. The publication period of the literature was limited to January 2016 to February 2023. Relevant literature on the preparation of PS animal models was retrieved from databases such as China National Knowledge Infrastructure, Wanfang database, and PubMed. After screening the experimental literature that met the inclusion and exclusion criteria, detailed information on experimental animal strains, modeling methods, duration of drug administration, positive drugs, detection indexes and other relevant information were collected. After the above information was standardized, the PS animal model database was established using Excel 2010 software. The model preparation elements and evaluation indexes were summarized systematically, and the statistical results were processed and analyzed using Excel 2010 software.Results A total of 247 articles were screened. SD rats (164 times, 65.86%) and Wistar rats (35 times, 14.06%) were often used to prepare PS animal models. Bilateral ovariectomy (139 times, 53.87%) and natural aging (43 times, 16.80%) were chosen as modeling methods. The ages of rats used for modeling ranged from 7 weeks to 18 months, with 3-month-old rats (22 times, 21.78%) being the most common. The detection indexes were comprehensively evaluated from multiple perspectives, including serum biochemistry, vaginal exfoliated cell smear, histomorphology, general observation, behavioral observation, and organ tissue protein immunoblotting. Western medical evaluation indexes were commonly used to test the successful preparation of models, with vaginal exfoliated cell smears being the most frequently used method (125 times, 85.04%). A model was considered successfully prepared when estrous cycle disorder or irregularity was observed. Some literature also determined modeling success by detecting a significant decrease in serum estradiol levels (5 times, 3.04%). Traditional Chinese medicine (TCM) syndrome evaluation often used a combination of Chinese and Western medical evaluation indexes for comprehensive evaluation, with researchers determining the TCM syndrome through vaginal exfoliated cell smears supplemented by general observation (3 times, 2.04%).Conclusion There are many methods for preparing PS animal models, but there are still significant differences in the selection of animal species, age, criteria for successful modeling, and TCM syndrome evaluation in the related literature.

Objective To investigate the key elements for model establishment and determine the evaluation indicators of animal models for pelvic inflammatory disease (PID), providing a reference for improving modelling methods and optimizing the application of PID animal models. Methods The search query "Pelvic Inflammatory Disease" AND "Animal Model" OR "Rat" OR "Mouse" OR" Guinea Pig" OR "Rabbit" OR "Dog" OR "Pig" was used to retrieve relevant literature on PID animal models published from 2013 to 2023 in China Knowledge Network Infrastructure (CNKI), Wanfang, and PubMed databases. The studies were analyzed and categorized based on experimental animal types, modelling methods, modelling cycles, detection indicators, positive control drugs, and administration duration. A database was established for statistical analysis. Results A total of 214 research articles on PID animal models meeting the inclusion criteria were identified. The most commonly used model animals are Sprague Dawley (SD) rats, followed by Wistar rats. The most frequently employed modelling method is a combination of mechanical injury and bacterial infection, followed by the phenol mucilage method. The most common modelling cycles for acute pelvic inflammatory disease (APID) and chronic pelvic inflammatory disease (CPID)/sequelae of pelvic inflammatory disease (SPID) are 8 to 14 days, while for PID models without specific staging, the cycles are 7 days. High-frequency detection methods and indicators include histopathological observation using hematoxylin-eosin staining, enzyme-linked immunosorbent assay (ELISA) for serum-related indicators, morphological changes of tissues observed with the naked eye, and immunohistochemical detection of related protein expression in uterine tissues, and pathological scoring. The most frequently used positive control drugs are Fuke Qianjin Tablets, followed by Jingangteng Capsules. The most common administration duration for APID is 7 days, and for CPID/SPID models, it ranges from 15 to 21 days. Conclusion Currently, SD rats and Wistar rats are commonly used as experimental animals for PID models. The dual modelling method of mechanical injury combined with mixed bacterial infection aligns closely with clinical pathogenesis and can be used to establish a PID model that simulates postoperative uterine cavity infection. Depending on the research objectives, different positive drugs and detection indicators should be selected for comprehensive evaluation. Most existing PID animal model studies are based on western medical diagnosis, with fewer studies focusing on Traditional Chinese Medicine (TCM) syndromes. There is a need to integrate TCM theories of etiology and pathogenesis to construct PID animal models that are more in line with TCM clinical symptoms.
