OBJECTIVE: To study the efficacy and safety of caffeine used in the early (≤72 hours after birth) and late (>72 hours after birth) stage in preterm infants with a gestational age of ≤31 weeks. METHODS: A retrospective analysis was performed for 640 preterm infants (with a gestational age of ≤31 weeks) who were admitted to the neonatal intensive care unit of eight hospitals in Jiangsu Province, China. Of the 640 preterm infants, 510 were given caffeine in the early stage (≤72 hours after birth; early use group) and 130 were given caffeine in the late stage (>72 hours after birth; late use group). The clinical data were compared between the two groups. RESULTS: There were no significant differences in birth weight, Apgar score, sex, gestational age, and age on admission between the two groups (P>0.05). Compared with the late use group, the early use group had a significantly younger age at the beginning and withdrawal of caffeine treatment (P<0.05) and a significantly shorter duration of caffeine treatment (P<0.05). There was no significant difference in respiratory support on admission between the two groups (P>0.05). Compared with the late use group, the early use group had significantly lower incidence rate of apnea (P<0.05) and significantly shorter oxygen supply time and length of hospital stay (P<0.05). There were no significant differences between the two groups in the incidence rates of neonatal intracranial hemorrhage, periventricular leukomalacia, necrotizing enterocolitis, retinopathy of prematurity, and patent ductus arteriosus at discharge and NBNA score at the corrected gestational age of 40 weeks (P>0.05). However, significant differences were found in the incidence of bronchopulmonary dysplasia and the rate of home oxygen therapy, but there was no significant difference in the mortality rate between the two groups (P>0.05). CONCLUSIONS Early use of caffeine can shorten the duration of caffeine treatment, oxygen supply time, and length of hospital stay, with little adverse effect, in preterm infants with a gestational age of ≤31 weeks.

OBJECTIVE: To observe the clinical effect of ' -- needling technique for diabetic fundus hemorrhage. METHODS: With before-after study design, 34 patients with diabetic eyeground hemorrhage were treated with basic treatment (oral administration of antidiabetic medication or insulin injections to ensure blood glucose in the normal range); in addition, acupuncture was given at bilateral Fengchi (GB 20), Taiyang (EX-HN 5), Jingming (BL 1), Cuanzhu (BL 2), Sanyinjiao (SP 6) and Hegu (LI 4). The ' -- needling technique was applied at Fengchi (GB 20); the heat reinforcing needling technique was applied at Taiyang (EX-HN 5); the slow needle insertion technique was applied at Jingming (BL 1); and the - needling technique was applied at Cuanzhu (BL 2); the neutral supplementation and draining method was applied at remaining acupoints. The acupuncture was given once a day, 6 times as one course, and totally 4 courses were given with an interval of 1 day between courses. The follow-up visit was 6 months after treatment. The TCM symptom scores, fundus examination results and vision improvement were observed before and after treatment, and the effect was observed. RESULTS: Compared before treatment, the visual acuity, TCM symptom scores, fundus microaneurysm and hemorrhage points in 34 patients (68 eyes) were significantly improved after treatment (<0.05). The total effective rate was 88.2% (60/68) after treatment; at follow-up visit, the visual acuity, TCM symptom scores and fundus pathological changes were all improved (<0.05) and stable at the post-treatment level (>0.05). CONCLUSION ' -- needling technique could improve symptoms, promote the absorption of fundus hemorrhage, and improve vision in patients with diabetic fundus hemorrhage.

Objective To indentify the cognitive status of Chinese patients to acne and the influencing factors to theirs' cognitive status,so as to provide solid evidences for the prevention and treatment of acne.Methods A self-designed questionnaire was made to conduct this survey of 16,156 acne patients,who seeked to the treatment in the dermatological departments from 112 hospitals in China.The survey consisted of several parts,including the general status of patients,the patients' cognition of occurrence,development and risk factors of acne,whether the first choice was seeking treatment at the hospital when the patients had acne and the condition of selection of skin care products.The factors were analyzed,which could impact the cognition of the patients' behavior of treatment,how did the patients' cognition to influence their medical behavior and skin care as well as the consistency of assessment of the severity of acne by doctors and patients themselves.Results The acne patients studied had the best knowledge of "acne is a skin disease","it not only occurs in the period of adolescence" and "the disease can be prevented and cured",which accordingly accounted for 80.65％,69.16％ and 65.49％ of the total patients respectively.However,the awareness of acne patients to heredity,high sugar and dairy products as risk factors for acne was insufficient,which accounted for 48.72％,42.40％ and 18.25％ of the total patients,respectively.Gender,age,educational level,occupation and health knowledge were the main factors affecting the cognitive level of patients;the survey also found that men,patient with educational level of junior high or even lower educational condition,occupation of labor workers or farmers and patients were lack of health education with poor knowledge of the genetics and dietary were risk factors for acne;patients with age over 36 years or with mild illness had poor knowledge of dietary risk factors for acne;the difference was statistically significant (P＜0.05).The analysis of the influence of cognitive status on medical treatment behavior and skin care showed that the better the cognition,the higher the probability of patients would choose medical treatment as the first choice as well as choosing functional skin care products;the difference was statistically significant (P＜0.05).The consistency of assessment of the severity of acne by doctors and patients was poor (Kappa value ＜0.4),and the assessment of severity of acne by patients was more serious than doctors' assessment.Conclusions Patient's cognitive status will affect their medical behavior and skin care,and there is also a phenomenon that patients have a more serious assessment of their acne condition.It is suggested that health education for acne patients should be strengthened in clinical medicine so as to improve their knowledge of acne as well as preventing from acne effectively.

Objective: To investigate the mechanism of Zuoguiwan in treating ovariectomy-induced osteoporosis rats by receptor activator of nuclear factor kappa-B ligand (RANKL)/osteoprotegerin (OPG) signaling pathway mediated by β₂-adrenergic receptor (β₂AR). Method: Forty Sprague-Dawley female rats were randomly divided into Sham-operated group (Sham) and four ovariectomized (OVX) subgroups. Rats in Sham and OVX groups were treated with 17β-estradiol (50 μg·kg^-1·d^-1), and low and high-dose ZGW (2.3,4.6 g·kg^-1 lyophilized powder) for 3 months, respectively. Enzyme-linked immunosorbent assay (ELISA) was used to measure the serum markers of bone turnover. Micro-CT was used to evaluate and measure trabecular bone microarchitecture and bone mineral density (BMD) of the right distal femur. Western blot analysis and Real-time PCR were used to measure mRNA and protein expressions of β₂AR, OPG and RANKL. Result: After 12 weeks of treatment with Zuoguiwan, the level of serum β-cross-linked c-telopeptide of type Ι collagen (β-CTX) (P<0.01) was lower, while the level of serum bone-specific alkaline phosphatase (BALP) was higher (P<0.01) than those in the OVX group. Moreover, it could prevent the OVX-induced bone loss, and alleviate the trabecular bone microarchitecture of distal femur. Furthermore, Zuoguiwan could up-regulate the mRNA and protein expressions of OPG in tibia of the Zuoguiwan groups(P<0.01), reduce the mRNA and protein expressions of β₂AR in the hypothalamus (P<0.01), and down-regulated the mRNA and protein expressions of RANKL (P<0.05) in the tibia, compared with those in the OVX group. Conclusion: The mechanism of Zuoguiwan in alleviating BMD and trabecular bone microarchitecture in ovariectomy-induced osteoporosis rats might be related to the regulation of RANKL/OPG Pathway mediated by β₂AR.

Zuoguiwan is a classic prescription for replenishing vital essence, tonifying kidney-Yin and nourishing the bone marrow. Zuoguiwan is one of the effective prescriptions for the prevention and treatment of osteoporosis (OP), which reflects the thought of Reinforcing Yang from Yin. The OP animal model simulates the pathological state and pathogenesis of OP in human, which is an important means to research the pathogenesis of OP and verify the effect of drugs. In this paper, two kinds of animal models and characteristics of Zuoguiwan in the prevention and treatment of osteoporosis were discussed in details. They are the primary osteoporosis animal models, including ovariectomized animal models and spontaneous elderly osteoporosis animal models, and the secondary osteoporosis models, including glucocorticoid-induced animal models, cyclophosphamide-induced animal models and subtotal nephrectomy animal models. The evaluation methods of Zuoguiwan in preventing and treating OP, including bone absorption markers and bone formation markers analyzed by enzyme-linked immunosorbent assay (ELISA), bone mineral density detected with dual-energy X-ray, the number of trabeculae, trabecular segregation, trabecular thickness, bone volume/tissue volume ratio and bone surface/volume ratio analyzed using micro-CT, bone pathological morphology observed by hematoxylin-eosin staining, bone biomechanical properties, such as the maximum load force based on biomechanical test. In order to provide scientific reference for the basic and clinical research of Zuoguiwan, the OP animal models and the pharmacodynamic effect of Zuoguiwan are evaluated comprehensively with five different and objective evaluation methods. However, the animal model of OP needs to be further optimized to highlight the pathogenesis and syndrome characteristics of Zuoguiwan in the treatment of OP.

Objective To investigate the proliferation potential of the basal stem cells in intralobar pulmonary sequestration syndrome (ILS) for revealing the pathogenesis of ILS. Methods In this study, lung tissue samples were collected from healthy control subjects(n=4)and abnormal lung lobes of ILS patients(n=4).The pathological changes were compared by HE staining between the two groups.The proportion of goblet cells was compared by PAS staining between the two groups.The expression and secretion of MUC5AC and MUC5B were compared by immunofluorescence staining and real-time PCR between the two groups. The distribution of ciliated cells and the proliferation of basal cells were compared by immunofluorescence staining between the two groups.Results The abnormal lobe of ILS group was filled with inflammatory cells, and the airway epithelium was disrupted. The airway goblet cells of ILS were obviously hyperplastic. The mucin proteins of MUC5AC and MUC5B were hypersecretion in the abnormal lobe of ILS patients.KRT5-positive basal stem cells proliferated only slightly in ILS patients, although there was no significant difference in KRT5 expression between two groups. Conclusion These data suggest that the pathogenesis of ILS may be associated with defects in basal stem cell function. Restoring airway integrity by targeting epithelial regeneration can be a future non-surgical treatment for patients with ILS.

Objective To explore the effect of the modular teaching for nursing students based on WeChat in the comprehensive training before the practice.Methods The undergraduate students of nursing were randomly divided into 5 classes,among which class 1,2,3 as the control group,and class 4,5 as the experimental group.The control group used the traditional ‘Case Teaching Method',taking the group as a unit to practice the clinical nursing skills individually;while the experimental group took the method which integrated individual nursing skills and practical materials with humanistic qualities in clinical cases.They conducted practical training by dividing the learning module with the ‘representative patients',using WeChat as the learning and exchange platform andbuilding modular training model.After the training,the results were evaluated by the score sheet for integrated skills,a critical-thinking scale and the learning model questionnaire.The data was analyzed by T-Test and Chi-Square inspection.Results All of the nursing students were willing to use WeChat for autonomous learning.The scores of the nursing students in the experimental group were higher than those in control group in the abilities of judgement,communication,operation and introspection.The difference was statistically significant (P＜0.05).In addition to the cognitive maturity,the scores of experimental group were higher than those in control group in the searching for truth,opening mind,abilities of analysis and integration and self-confidence in critical thinking and desire for knowledge,The difference was statistically significant (P＜0.05);Also the proportion of experimental group was higher than the control group in students' attitude to study,knowledge acquisition and practical training mode.The difference was statistically significant (P＜0.05).Conclusion The implementation of nodular teaching mode based on WeChat is beneficial to improve the clinical comprehensive ability of nursing students,and help to train the high quality nursing talents who meet the needs of clinical practice.

Objective To investigate current status of hemodialysis,and qualified status of dialysis water and dia-lysate in a city. Methods Status of hemodialysis in 36 medical institutions in a city which conducted blood purifica-tion programme was surveyed,dialysis water and dialysate were collected to perform microbial detection(including conventional and low temperature culture methods)and on-site ATP detection.Results 13.89% of equipments for water treatment were used less than 1 year,5.56% were used for more than 10 years. 77.78% of medical institu-tions didn't replace sand filtration which had been used for more than 1 year,the replacement time of 72.22% of fil-ter core was less than 3 months,2.78% of reverse water supply pipeline was used for more than 10 years.77.78%of medical institutions used finished A solution,72.22% used finished B solution,22.22% used centrally provided A solution,19.44% used centrally provided B solution,and 8.34% used self-made B solution. Routine microbial detection in 36 medical institutions were qualified,but 80.56% of detection results were"0" value for long period;ATP detection of on-site collected dialysis water and dialysate were all qualified. One specimen for microbial detec-tion under normal temperature exceeded the standard,2 reached the intervention value;4 specimens for microbial detection under low temperature exceeded the standard,6 reached the intervention value;qualified rates of 3 kinds of detection methods among different levels of medical institutions weren't significantly different(all P>0.05).Con-clusion The overall quality of hemodialysis water and dialysate in this city is good,the majority of medical institutions pay attention to the routine maintenance of water treatment equipment,detect the quality of hemodialysis water and dialysate regularly,but microbial detection technique needs to be improved,causes for abnormal results or intervention value of rou-tine detection needs to be analyzed and improved continuously.

Objective To compare the feasibility and safety of laparoscopic partial renal segmental artery occlusion and renal artery trunk interruption for partial nephrectomy. Methods We reviewed medical records of 65 patients with stage T1 renal tumor from October 2013 to February 2017. Among them, 29 cases underwent partial nephrectomy with high selective segmental renal artery occlusion, and 36 cases underwent partial nephrectomy with renal artery trunk occlusion. Then compare the preoperative and postoperative creatinine changes, intraoperative blood loss, warm ischemia time, operation time, hospitalization time and positive margins of the two methods. Results In all the patients, the procedures were done without conversion to open surgeries. The operation time of the renal artery branch block group is shorter than that of the main renal artery block, but the preoperative and postoperative creatinine changes are smaller than those of the main renal artery occlusion group. There was no significant difference between the two groups in intraoperative blood loss, warm ischemia time and positive margins (P > 0.05); There was no significant difference between the two groups in age, body mass index (BMI) and R.E.N.A.L score of renal tumor (P > 0.05). Conclusion For the stage T1 renal tumor, the selective renal artery branch interruption technique has a longer operation time, but the renal tissue has a small ischemic zone and has little effect on the kidney.
