BACKGROUNDInfants in some areas of China developed urinary lithiasis after being fed with powdered milk that was tainted with melamine in 2008 and very small proportion of the infants developed acute renal failure caused by urinary tract calculus obstruction. The aim of this article was to summarize clinical characteristics, diagnosis and treatment of infants with urinary calculus and acute renal failure developed after being fed with melamine tainted formula milk.

METHODSData of infant patients with urinary calculus and acute renal failure due to melamine tainted formula milk admitted to the Beijing Children's Hospital Affiliated to the Capital Medical University and the Xuzhou Children's Hospital in 2008 were used to analyze the epidemiological characteristics, clinical manifestations, imaging features as well as effects of 4 types of therapies.

RESULTSAll the 34 infants with urinary calculus were complicated with acute renal failure, their blood urea nitrogen (BUN) was (24.1+/-8.2) mmol/L and creatinine (Cr) was (384.2+/-201.2) micromol/L. The chemical analysis on the urinary calculus sampled from 15 of the infants showed that the calculus contained melamine and acidum uricum. The time needed for the four types of therapies for returning Cr to normal was (3.5+/-1.9) days for cystoscopy group, (2.7+/-1.1) days for lithotomy group, (3.8+/-2.3) days for dialysis group, and (2.7+/-1.6) days for medical treatment group, which had no statistically significant difference (P=0.508). Renal failure of all the 34 infants was relieved within 1 to 7 days, averaging (3.00+/-1.78) days.

CONCLUSIONSMelamine tainted formula milk may cause urinary calculus and obstructive acute renal failure. It is suggested that firstly the patients with urinary calculus complicated with acute renal failure should be treated with dialysis or medication to correct electrolyte disturbance, in particular hyperkalemia, and then relieve the obstruction with available medical and surgical methods as soon as possible. It was observed that the short-term prognosis was satisfactory.

Classical famous prescription Dihuang Yinzi is widely used in modern clinical practice，and can treat many kinds of diseases，especially the diseases of nervous system in internal medicine. Its clinical effect is accurate，but it has not been converted into Chinese patent medicine preparations. Therefore，the authors have collected ancient traditional Chinese medicine（TCM） literatures of Dihuang Yinzi by the methods of bibliometrics，and selected and sorted out 254 pieces of effective data， involving 144 ancient books of TCM，and systematically summarized and analyzed the historical development origin，main treatment syndrome，formula making principle，dosage，preparation method，decoction method and medicine taking method of Dihuang Yinzi，in order to provide the ancient literary evidence support for the development and clinical application of classic famous prescriptions. It is found that Dihuang Yinzi was from Xuanming Lunfang written by LIU He-jian，a doctor of Jin dynasty. It was composed of 12 kinds of herbs，namely Rehmanniae Radix Praeparata，Morindae Officinalis Radix，Corni Fructus，Cistanches Herba，Dendrobii Caulis，Aconm Lateralis Radix Praeparaia，Schisandrae Chinensis Fructus，Cinnamomi Ramulus，Poria，maimendong，Acori Calami Rhizoma and Polygalae Radix, and mainly used for the treatment of Yinfei. The later records of Dihuang Yinzi mostly followed the prescription composition and main treatment set forth in Xuanming Lunfang，and its clinical application was expanded. In the 199 articles with the indications for disease treatment，Yinfei was the most commonest indication, and took up about half of the total，which was followed by stroke，taking up about two fifths of the total. It was also used for the treatment of sudden aphonia，flaccidity syndrome，vertigo，enuresis. Dihuang Yinzi has a wide range of treatment，but the pathogenes is always belongs to "the deficiency of water and fire in the kidney". The recipe of Dihuang Yinzi was unique，and can be used to treat both the upper and lower parts of the body，as well as both the outward symptoms and root causes of an illness at the same time， in particular，it mainly focuses on the treatment of the lower and the root. Among the 56 literatures with drug dosage records，about one third of them inherited the records of Xuanming Lunfang: "Equal division，the top is the end，3 qian for each dose." The dosage was generally light. The preparations are mostly decoction and boiled powder. In the decocting and taking methods，it was suggested that "turbid medicine shall be boiled for a short time，and taken after several boilings，with no limit to time."

OBJECTIVETo understand the prevalence of informing doctors of the HIV infection status during medical care seeking and influential factors among people living with HIV/AIDS.

METHODSThe study was conducted among people living with HIV/AIDS in 7 provinces in China, including those receiving HIV test, HIV counsel and HIV infection treatment. The data were analyzed with software SAS 9.2. Chi-square test was used to compare the informing rates in patients with different characteristics. Univariate and multivariate logistic regression analyses were conducted to identify the influential factors.

RESULTSOf the 2 432 HIV/AIDS patients, 49.7% (716/1 442) didn't inform the doctors of their HIV infection status actively. The non-active informing rate was 51.9% (559/1 077) in males, 62.9% (212/337) in age group 18-30 years old, 58.1% (555/955) in those with a educational level >primary school, 65.7% (241/367) in those working in private/joint companies or the self employed and 62.5% (197/315) in those living in small cities. The non active informing rate was highest in those infected through sexual contact (66.3%, 275/415). Multivariate logical regression analysis indicated that those infected through illegal blood donation would like to inform of the HIV infection status actively (OR=0.083, 95% CI: 0.049-0.141) , but those working in private/joint companies or the self employed would like not to inform of the HIV infection status actively (OR=1.531, 95% CI: 1.017-2.304).

CONCLUSIONThe non active informing rate of HIV infection status was high in people living with HIV/AIDS. It is necessary to conduct the targeted health education to encourage people living with HIV/AIDS to inform of their HIV infection status actively.

Objective:To analyze the risk factors of bronchopulmonary dysplasia(BPD)in very preterm infants(VPI), and to provide scientific basis for the prevention and treatment of BPD in VPI.Methods:A prospective multicenter study was designed to collect the clinical data of VPI in department of neonatology of 28 hospitals in 7 regions from September 2019 to December 2020.According to the continuous oxygen dependence at 28 days after birth, VPI were divided into non BPD group and BPD group, and the risk factors of BPD in VPI were analyzed.Results:A total of 2 514 cases of VPI including 1 364 cases without BPD and 1 150 cases with BPD were enrolled.The incidence of BPD was 45.7%.The smaller the gestational age and weight, the higher the incidence of BPD( P<0.001). Compared with non BPD group, the average birth age, weight and cesarean section rate in BPD group were lower, and the incidence of male infants, small for gestational age and 5-minute apgar score≤7 were higher( P<0.01). In BPD group, the incidences of neonatal respiratory distress syndrome(NRDS), hemodynamically significant patent ductus arteriosus, retinopathy of prematurity, feeding intolerance, extrauterine growth restriction, grade Ⅲ~Ⅳ intracranial hemorrhage, anemia, early-onset and late-onset sepsis, nosocomial infection, parenteral nutrition-associated cholestasis were higher( P<0.05), the use of pulmonary surfactant(PS), postnatal hormone exposure, anemia and blood transfusion were also higher, and the time of invasive and non-invasive mechanical ventilation, oxygen use and total hospital stay were longer( P<0.001). The time of starting enteral nutrition, cumulative fasting days, days of reaching total enteral nutrition, days of continuous parenteral nutrition, days of reaching 110 kcal/(kg·d) total calorie, days of reaching 110 kcal/(kg·d) oral calorie were longer and the breastfeeding rate was lower in BPD group than those in non BPD group( P<0.001). The cumulative doses of amino acid and fat emulsion during the first week of hospitalization were higher in BPD group( P<0.001). Multivariate Logistic regression analysis showed that NRDS, invasive mechanical ventilation, age of reaching total enteral nutrition, anemia and blood transfusion were the independent risk factors for BPD in VPI, and older gestational age was the protective factor for BPD. Conclusion:Strengthening perinatal management, avoiding premature delivery and severe NRDS, shortening the time of invasive mechanical ventilation, paying attention to enteral nutrition management, reaching whole intestinal feeding as soon as possible, and strictly mastering the indications of blood transfusion are very important to reduce the incidence of BPD in VPI.

Objective To investigate the status of exclusive breastfeeding and bottle feeding in remote rural areas of Sichuan province and explore the relationship between negative emotions of mothers and feeding patterns of infants.Methods Multistage cluster sampling was employed to select the infants aged 0-6 months and their mothers in remote rural areas of Sichuan province.A self-designed questionnaire was used to collect the demographic characteristics of mothers and infants and the basic family information.The Chinese version of Depression Anxiety Stress scale was used to evaluate mothers' negative emotions,and the Breastfeeding Self-efficacy scale to assess the confidence level of mothers' behavior of adhering to exclusive breastfeeding.Results Totally 723 pairs of infants and their mothers were included.The exclusive breastfeeding and bottle feeding rates were 34.16% (247/723) and 57.54% (416/723),respectively.Mothers with depression tendency were less likely to adopt exclusive breastfeeding (OR=0.532,95%CI=0.291-0.974,P=0.041) and more likely to adopt bottle feeding (OR=1.877,95%CI=1.054-3.344,P=0.033).Further subgroup analysis of breastfeeding self-efficacy showed that in the group of low self-efficacy,the mothers with depression tendency were less likely to adopt exclusive breastfeeding (OR=0.461,95%CI=0.236-0.902,P=0.024) and more likely to adopt bottle feeding (OR=1.968,95%CI=1.047-3.701,P=0.036) than the mothers without depression tendency.In the group of high self-efficacy,mothers' depression,anxiety,and stress tendency had no significant correlation with infant feeding patterns (all P>0.05).Conclusions The mothers in the remote rural areas of Sichuan province are more likely to employ bottle feeding than exclusive breastfeeding.The mothers with stronger depression tendency demonstrate lower possibility of exclusive breastfeeding and higher possibility of bottle feeding.Breastfeeding self-efficacy may affect the association between maternal depression and infant feeding patterns.

As a modern dosage form drug with rapid effect, traditional Chinese medicine (TCM) injection has been more and more used in clinical practice. Meanwhile the safety of TCM injection has attracted more and more attention. The retrospective analysis on 74 cases of adverse reaction of TCM injections collected from 2007 to 2016 in the Third Affiliated Hospital of Beijing University of Chinese Medicine showed that the proportion of men and women with adverse reactions was 0.54:1; the average age was 62.5 years old; 21 kinds of TCM injections were involved. Among them, the most reported were blood-regulating agents. The top four kinds of TCM injections with highest adverse drug reactions (ADRs) were Tanreqing injection, Danhong Injection, Shuxuening Injection and Xuesaitong for injection. The top three clinical manifestations of adverse reactions were lesions of skin and its appendages, damage of circulatory system and damage of nervous system. The potential causes of the adverse reactions of TCM injections were analyzed, and it was believed that individual difference, medicine, pharmaceutical excipients, solvent and TCM syndrome differentiation may be the main five causes for the adverse reactions of TCM injections. In order to reduce the adverse reactions of TCM injections, it is suggested that the clinical pharmacists should participate in the application management of TCM injections in the hospital; the production enterprises shall strengthen the whole life cycle management of the drugs; and at the same time, the drug control and administration authorities should improve the drug management methods constantly and encourage the development of TCM injections to the high quality level.

Objective To understand the current situation and explore the influencing factors of delay in seeking medical treatment for common symptoms of residents in the rural areas of Sichuan province. Methods In July 2019,multi-stage random sampling was carried out in Zigong city,Sichuan province,and the data were collected by face-to-face questionnaire interview.The residents who had lived at hometown for more than half a year in the past year and had seen a doctor in the most recent month were surveyed.Logistic regression was adopted to predict the influencing factors of delay in seeking medical treatment. Results A total of 342 subjects were enrolled,and the incidence of delay in seeking medical treatment was 13.45%(46/342).Compared with the young and middle-aged(<65 years)people,the elderly(≥65 years)people were more likely to have delay in seeking medical treatment (OR=2.187,95%CI=1.074-4.457,P=0.031).The rural residents who gave higher score of the overall quality of township health centers were less likely to have delay in seeking medical treatment (OR=0.854,95%CI=0.735-0.992,P=0.039). Conclusions The occurrence of delay in seeking medical treatment for common symptoms of rural residents in Sichuan province is low.Age and the overall quality evaluation of township health centers affect the occurrence of delay in medical treatment among the rural residents in Sichuan province.Efforts should be made to improve the awareness of disease prevention among the elderly in rural areas.The investment in health resources in township health centers should be increased to strengthen the introduction and training of talents.These measures can improve the health services in township health centers,guide residents to make timely use of health resources,and reduce the occurrence of delay in seeking medical treatment.

Vacuum sealing drainage (VSD) is frequently used in abdominal surgeries. However, relevant guidelines are rare. Chinese Trauma Surgeon Association organized a committee composed of 28 experts across China in July 2017, aiming to provide an evidence-based recommendation for the application of VSD in abdominal surgeries. Eleven questions regarding the use of VSD in abdominal surgeries were addressed: (1) which type of materials should be respectively chosen for the intraperitoneal cavity, retroperitoneal cavity and superficial incisions? (2) Can VSD be preventively used for a high-risk abdominal incision with primary suture? (3) Can VSD be used in severely contaminated/infected abdominal surgical sites? (4) Can VSD be used for temporary abdominal cavity closure under some special conditions such as severe abdominal trauma, infection, liver transplantation and intra-abdominal volume increment in abdominal compartment syndrome? (5) Can VSD be used in abdominal organ inflammation, injury, or postoperative drainage? (6) Can VSD be used in the treatment of intestinal fistula and pancreatic fistula? (7) Can VSD be used in the treatment of intra-abdominal and extra-peritoneal abscess? (8) Can VSD be used in the treatment of abdominal wall wounds, wound cavity, and defects? (9) Does VSD increase the risk of bleeding? (10) Does VSD increase the risk of intestinal wall injury? (11) Does VSD increase the risk of peritoneal adhesion? Focusing on these questions, evidence-based recommendations were given accordingly. VSD was strongly recommended regarding the questions 2-4. Weak recommendations were made regarding questions 1 and 5-11. Proper use of VSD in abdominal surgeries can lower the risk of infection in abdominal incisions with primary suture, treat severely contaminated/infected surgical sites and facilitate temporary abdominal cavity closure.
