OBJECTIVE:To investigate the influence of health education prescription on the reduction of intravenous dripping leakage in obstetrics and gynecology department of our hospital. METHODS:Totally 300 inpatients selected from obstetrics and gy-necology department of our hospital Jun.-Nov. 2015 were divided into observation group and control group according to random number table,with 150 cases in each group. Control group received health education of daily operation during intravenous dripping. In observation group,intravenous dripping treatment card came with a health education prescription of intravenous dripping,which facilitate the patients and families to consult;the nurses carried out health education for patients every day during dripping in accor-dance to the prescriptions;clinical pharmacists accompanied resident physicians to make patient round and conducted random health education inspection. Awareness rate of health education prescription content,satisfactory rate of treatment,dripping rate of Magne-sium sulfate injection and Cefazolin sodium for injection,the incidence of ADR were compared between 2 groups. The intravenous dripping leakage were observed in 2 groups. RESULTS:The awareness rate of health education prescription content and satisfactory rate of treatment were 94.0% and 96.0% in observation group,which was significantly higher than 70.35% and 85.75% of control group,with statistical significance (P<0.05). The dripping rate of Magnesium sulfate injection <40 drops/min accounted for 97.6% in observation group,which was significantly higher than 91.6% of control group;the incidence of ADR was 0.3% in ob-servation group,which was significantly lower than 1.3% of control group. The dripping rate of Cefazolin sodium for injection <60 drops/min accounted for 92.3%,which was significantly higher than 85.0% of control group;the incidence of ADR was 0.4%in observation group,which was significantly lower than 1.0% of control group,with statistical significance(P<0.05). The intra-venous dripping leakage rate was 5.5%in observation group,which was significantly lower than 9.5%of control group,with statis-tical significance(P<0.05). CONCLUSIONS:Health education prescription can significantly improve satisfactory degree of treat-ment and reduce ADR and leakage during intravenous dripping

In light of the IT development in hospitals, the authors point out the necessity of setting up the post of CIO and clarify the role of the CIO in the construction and management of the hospital information system. They argue that the CIO should not only be in charge of the technology support of the information network platform, but also exercise the function of managing hospital information. While hospitals ought to attach importance to the development and application of information systems and the role of the CIO, the CIO, on his part, ought to try to enhance his competence and become a versatile talent expert at various disciplines like medicine, management and the computer.

Objective To explore the potential association between HLA-DRB1 Alleles and systemic scleroderma (SSc) of the Zhuang Nationality in Guangxi region. Methods Polymerase chain reaction-special sequence primers (PCR-SSP) was used to study the HLA-DRB1 alleles in 58 patients with SSc and 50 healthy controls of the Zhuang Nationalty in Guangxi Province. Comparisons between groups were performed with χ2 test or exact probabilities. Results Sixteen HLA-DRB1 alleles were discovered from the specimens,including 14 in the SSc specimens, and 16 in the control specimens. Among them,the allele frequencies of HLA-DRB1 * 1301 (7.760%, OR=9.000, χ2=4.341, P=0.037), HLA-DRB1 * 1305 (11.207%, OR=3.322,χ2=4.206, P=0.040) and DRB1 * 15 (26.724%, OR=2.679, χ2=6.038, P=0.014) were significantly higher in SSc patients than those of the controls (respectively for 1.000%, 4.000%, 15.000%). Conclusion Our data suggest that the HLA-DRB1 * 1301, HLA-DRB1 * 1305 and HLA-DRB1 * 15 may be the susceptible genes of SSc in Zhuang nationality population.

ObjectiveTo assess the effects of intra-articular Hydromorphone with Ropivacaine for postoperative analgesia after arthroscopic knee surgery.Methods 90 patients undergoing arthroscopic knee surgery were randomly divided into 3 groups. Group R: 0.375% Ropivacaine 20ml; group H1: Hydromorphone 0.3 mg and 0.375 % Ropivacaine 20 ml; group H2: Hydromorphone 0.6 mg and 0.375 % Ropivacaine 20 ml. The visual analogue scale (VAS) at rest were recorded at 6, 12, 18 and 24 h after surgery, Duration of analgesia, number of patients and frequency requiring Parecoxib at 24 h after surgery were observed.Results Compared with group R, VAS of group H1 and group H2 were signiifcantly lower at 12 and 18h after the operation, duration of analgesia was much longer, number of patients and frequency requiring Parecoxib was lower in group H1 and H2 (P < 0.05); Compared with group H1, No signiifcant differences of VAS, duration of analgesia and number of patients and frequency requiring Parecoxib of group H2.Conclusions After knee arthroscopic surgery, intra-articular 0.3 mg Hydromorphone can signiifcantly improve the efifcacy of Ropivacaine for postoperative analgesia; the efifcacy of Hydromorphone can’t increased with the increase of dosage.

Objective To evaluate the effect of propofol on liver injury in mice with acute liver failure (ALF).Methods Eighty adult male ICR mice,aged 1 months,weighing 20-25 g,were randomly divided into 3 groups (n =20 each) using a random number table:control group (group Ⅰ),ALF group (group Ⅱ),and ALF + propofol group (group Ⅲ).ALF model was established with intra-peritoneal D-galactosamine (D-GaIN) and lipopolysaccharide (LPS).Propofol 5 mg/kg was injected via the tail vein every 1 h within 6 h after injection of DGaIN and LPS in group Ⅲ,while the equal volume of normal saline was given instead in the other groups.Venous blood samples were taken from the tail vein at 1,3 and 6 h after injection of D-GaIN and LPS (T1-3) to detect the activities of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) and serum tumor necrosis factor-alpha (TNF-α),interleukin-1β (IL-1β) and IL-10 concentrations (by ILISA).The survival within 12 h after injection of D-GaIN and LPS was observed and the survival rates were calculated.The mice were sacrificed and livers were removed for microscopic examination of pathologic changes.Results Compared with group Ⅰ,the activities of AST and ALT were significantly increased at each time point in Ⅱ and Ⅲ groups and the serum TNF-α concentrations at T1,2 and IL-1β and IL-10 concentrations at each time point were significantly increased in group Ⅱ,and the serum TNF-α concentrations at T1,and IL-1β and IL-10 concentrations at T2,3 were significantly increased in group Ⅲ (P ＜ 0.05).Compared with group Ⅱ,the activities of AST and ALT at each time point,serum TNF-α concentrations at T1,2 and IL-1β and IL-10 concentrations at T2,3 were significantly decreased and the survival rate within 12 h after injection of D-GaIN and LPS was increased in group Ⅲll (P ＜ 0.05).The pathologic changes of liver tissues were gradually attenuated in Ⅱ and Ⅲ groups.Conclusion Propofol can reduce the liver injury in mice with ALF through inhibiting inflammatory responses.

Objective To investigate the relationship between abnormalities of maternal serum markers in Down syndrome screening in second trimester and adverse pregnancy outcome.Methods Totally,1935 pregnant women were screened for Down syndrome with maternal serum tri marker with time-resolved fluorescence assay,including alpha fetoprotein (AFP),free β-human chorionic gonadotropin (β-hCG) and unconjugated estriol (uE3),between 15 and 20+6 gestational weeks at Peking Union Hospital from January 1,2009 to January 31,2011,and were followed up till delivery.The relationship between incidence of adverse pregnancy outcomes and women with normal or abnormal levels of serum markers in Down syndrome screening was investigated.T-test or Chi-square test were applied for statistical comparison.Results (1) Among the 1935 pregnant women,normal levels of serum markers were found in 1255(normal group) and 680 were abnormal(abnormal group),in which 577 with only one abnormal serum marker,89 with two and 14 with three abnormal serum markers.According to the serum marker level,the 577 women with one abnormal serum marker were further divided into five groups,including high AFP group (n=17),low AFP group (n=114),high β-hCG group (n=242),low β-hCG group (n=139) and low uE3 group (n=65).The birth weight of infants in lower AFP group and the gestational age at delivery in low β-hCG group were greater than those in normal group [(61.3±9.1) kg vs (59.5±8.3) kg,(272.6±11.8) d vs (274.4±10.1) d,t=2.21 and 1.99,both P＜0.01].(2) The incidence of adverse pregnancy outcome in normal group was 42.8％(537/1255),while comparing with the abnormal group(43.7％,297/680),no statistical significance was shown (RR =1.02,P =0.71).While comparing with the normal group,the incidences of placenta previa [25.5％ (32/1255) vs 2/17,RR=4.61,P＜0.05] and abnormal placental morphology were higher in high AFP group [4.1％ (51/1255) vs 5/17,RR=7.24,P＜ 0.05],the incidence of gestational diabetes mellitus (GDM) was higher in low AFP group [8.1％ (101/1255) vs 14.4％(16/114),RR=1.74,P＜0.05],the incidence of placenta and membrane retention was higher in high β-hCG group [3.5％ (44/1255) vs 6.2％(15/242),RR=1.77,P＜0.05],the incidence of pre-eclampsia was higher in low β-hCG group [1.7％ (21/1255) vs 6.5％ (9/ 139),RR=3.87,P＜0.05].(3) There were 89 women with two abnormal serum markers.Comparing with the normal group,the incidences of small for gestional age (SGA) infants,oligohydramnios,abruptio placenta were higher in women with low AFP but high β-hCG [SGA infants:6.9％(2/29) vs 1.8％(22/1255),RR=3.94; oligohydramnios:20.7％(6/29) vs 6.4％(80/ 1255),RR=3.24; both P＜0.05],the incidences of oligohydramnios was higher in women with both low AFP and low uE3[3/14 vs 6.4％(80/1255),RR=3.36,P＜0.05],the incidence of premature birth and GDM were higher in women with both low β-hCG and low uE3 [premature birth:2/6 vs 4.3％(54/1255),RR=7.75; GDM:3/6 vs 8.0％ (101/1255),RR=6.21; both P＜0.05].(4) There were 14 women with three abnormal serum markers.The relationship between adverse outcome and abnormal serum markers did not show any statistical significance.Conclusions The abnormality of serum markers of Down syndrome screening is closely related to adverse pregnancy outcomes,and women with abnormal serum markers should be carefully monitored during pregnancy.

BACKGROUND: Pilon fractures are mainly vertical compression violence involving the tibia distal articular surface fracture, especially the high-energy damage Pilon fracture. Pilion fracture is characterized by obvious fracture displacement, different levels of compression, crushing at stem epiphyseal end, unstable height, primary articular cartilage injury and uneven joint surface. Because it is difficult to treat, and holds various complications and high morbidity, it becomes a challenge in the field of orthopedics. Good preoperative planning and design can reduce the occurrence of complications and obtain good clinical treatment outcomes. OBJECTIVE: To explore the clinical effect of three-dimensional printing technology combined with virtual surgery design in the treatment of complex Pilon fractures. METHODS: Eighty-eight patients with complex Pilon fracture at Yulin Orthopedics Hospital of Chinese and Western Medicine from August 2017 to November 2018 were selected and divided into two groups (three-dimensional printing group, n=38; control group, n=50). The three-dimensional printing group was treated with three-dimensional printing technology combined with virtual surgery design, and the control group was treated with conventional surgery. The operation time, blood loss, incision length, one-time successful placement rate, postoperative ankle function recovery and healing were recorded. RESULTS AND CONCLUSION: (1) The three-dimensional printing group was superior to the control group in terms of operation time, blood loss, incision length, one-time successful placement rate, reduction satisfaction (Burwell-Charnley fracture reduction radiology evaluation), functional recovery degree (Mazur ankle joint score) after 12-month follow-up and wound healing (P < 0.05). (2) To conclude, compared with conventional surgery, three-dimensional printing combined with virtual surgery design for treating complex Pilon fractures can shorten the operation time, reduce surgical trauma and blood loss, and achieve satisfactory fracture reduction and functional recovery.

Objective To explore the relationship between expected drop and postpartum depression,analysis of influence factors of postpartum depression.Methods Chinese version of Postpartum Support Questionnaire and Edinburgh Postnatal Depression Scale were used to investigate 411 puerpera of 42-56 days postpartum by the convenience sampling method.Results The incidence rate of postpartum depression was 17.03％ (70/411).The correlation coefficient r between the actual situation of postpartum social support and the score of each dimension and the score of Edinburgh Postpartum Depression Scale was 0.157 to 0.247 (P ＜ 0.01).The correlation coefficient r between the postpartum social support expectation drop and the Edinburgh Postpartum Depression Scale score was 0.173 to 0.230 (P ＜ 0.01).Regression analysis showed postpartum depression was related to emotional support,nursing mode,registered permanent residence and gender expectations for baby.Conclusions The positive rate of postpartum depression is still higher.How to reduce the incidence of postpartum depression is still a problem to be solved.According to the characteristics of social support and maternal postpartum to evaluate the importance of targeted social support can reduce the incidence of postpartum depression.
