Objective To explore the effect of family visit and nursing intervention in promoting the re-habilitation of thoracolumbar fracture patients. Methods 115 patients with thoracohmbar fracture were divid-ed into the study greup(60 cases) and the control group(55 cases) by random hospitalization number. Patients in the study group were given regularly rehabilitation guidance initiatively at home by doctors and nurses for 6 months since discharge, the control group received conventional discharge guidance. Results After the inter-vention, the two groups showed significant difference in the functional rehabilitation, awareness rate of disease-related knowledge, mastering rate of relevant skills, incidence rate of complication, satisfaction degree with nursing. Conclusions Regular family visit and nursing intervention by the doctors and nurses can not only teach patients relative functional exercise methods, promote the physical rehabilitation of limbs, reduce inci-dence of complications and solve the problem of lack of care support after discharge from hospital effectively.

A total of 26 patients comprising 14 with delayed fracture healing and 12 with bone nonunion were treated via subperiosteum and fractured spatial injection of osteoblasts. Bone marrow was extracted from posterior superior lilac spine to obtain osteoblasts following in vitro induction, culture and amplification. Subsequently, 5-8 mL osteoblasts at a density of 1 ×105 cells/mL was sterilely injected into subperiosteum and fractured interspace in injured region using X-ray positioning. At 4, 6, 10 and 14 weeks after injection, callus formation was checked using X-ray. All cases followed up for 3-12 months, with the means of 5.3 months. Callus was formed after 4 weeks, fractured ends were wrapped up by callus after 6 weeks, and fracture line was unclear after 10 weeks and disappeared after 14 weeks. Bone fracture was healed, with the mean healing time of 12.1 weeks, suggesting that percutaneous subperiosteum injection of osteoblasts is an effective method to treat delayed fracture healing and bone nonunion.

Objective To investigate the application value of serum pancreatic isled autoantibodies and biochemical indicators in classification diagnosis of type 1 diabetes mellitus (T1DM ) and type 2 diabetes mellitus (T2DM ) .Methods The clinical data and laboratory detection results in 99 cases of T1DM and 577 cases of T2DM were retrospectively analyzed .The levels of pancreatic isled autoantibodies and biochemical indicators were compared between the two groups and their characteristics were analyzed .Re‐sults The positive rates of single detection and combine detection of glutamic acid decarboxylase autoantibodies (GADA) ,insulino‐ma‐associated antigen‐2 autoantibodies (IA‐2A ) ,islet cell autoantibodies (ICA ) and ZnT8 autoantibodies (ZnT8A ) in the T1DM group were higher than those in the T2DM group ,the differences were statistically significant (P<0 .05) .The onset age ,fasting and postprandial 2 h CP ,fasting and postprandial 2 h insulin(2 h INS) ,triglyceride(TG) and body mass index (BMI) in the T1DM group were lower than those in the T2DM group ,while the levels of fasting and postprandial 2h blood glucose ,glycosylated hemo‐globin(HbA1c) and high‐density lipoprotein cholesterol(HDL‐C) were higher than those in the T2DM group ,the differences were statistically significant (P<0 .05);however total cholesterol and low‐density lipoprotein cholesterol levels had no statistical differ‐ence between the T1DM group and T2DM group (P>0 .05) .Moreover ,the fasting and postprandial 2 h CP levels in the T1DM group showed decreasing trend as the T1DM course extending ,and the difference had statistical difference among different disease courses ;but the fasting and postprandial 2 h CP levels in the T2DM group had no obvious decreasing trend .The areas under the receiver operating characteristic(ROC) curve of fasting and postprandial 2 h CP for differential diagnosis of T1DM and T2DM in the patients with the disease course < 2 year were 0 .902(95% CI:0 .850-0 .954) and 0 .905(95% CI:0 .852-0 .958) respective‐ly .The suitable threshold value of fasting CP was 0 .283 nmol/L ,its sensitivity and specificity were 82 .6% and 89 .2% ,respective‐ly ,which of postprandial 2 h CP was 0 .421 nmol/L ,its sensitivity and specificity were 84 .8% and 89 .2% respectively . Conclusion T1DM and T2DM are different in onset age ,BMI value ,serum GADA ,IA‐2A ,ICA ,ZnT8A ,insulin ,CP ,glucose , HbA1c ,TG and HDL‐C levels ,which may assist clinic in their classification diagnosis .

Objective To investigate the relationship between estrogen levels and tenosynovitis in postm-enopausal women. Methods 74 cases of postmenopausal women,including 32 cases of tenesynovitis (group A),42 cases healthy postrnenopausal women for the control group (group B) were observed. 42 cases of normal menstruation women were taken as control group (group C). Results The estrogen level was (89.7066±126.7458) pmol/L in group A,(45.6768±30.6342) pmol/L in group B,and (626.7384±361.5348)pmol/L in group C,There is statistical difference between group A and group C (P<0.05). Conclusions Tenosynovitis incidence in postmeno-pausal women has no significant relationship with the level of estrogen change.

Objective To explore the incidence of surgical site infection (SSI)and compliance to bundled interven-tion measures,and evaluate the effect of bundled interventions on controlling SSI.Methods From October 2013 to September 2014,three types of surgeries (colorectal surgery,abdominal hysterectomy,and femoral neck repair sur-gery)in 29 hospitals in China were monitored,October 2013 to March 2014 was baseline investigated stage,April 2014 to September 2014 was intervention stage.Results A total of 6 166 episodes of surgeries were monitored,the incidence of SSI was 1 .64%,incidence of SSI following colorectal surgery,abdominal hysterectomy,and femoral neck repair surgery were 4.47%,1 .03%,and 0.21 % respectively.The P 75 time of three types of surgeries were 3,2,and 2 hours respectively.Compared with the baseline stage,the compliance to most intervention measures im-proved after intervention,the largest increase in the compliance to interventions was disinfection with chlorhexidine-containing disinfectant at surgical sites of colorectal surgery (increased by 29.09%),followed by preoperative shower of femoral neck repair surgery (increased by 26.24%),preoperative shower of colorectal surgery(increased by 22.95%),and skin preparation on the day of operation (increased by 20.75%).Incidences of SSI in three types of surgeries were not significantly different before and after intervention(all P >0.05).Conclusion The incidences of SSI are different among different types of surgeries,the compliance to most bundled intervention measures has im-proved to some extent after intervention,but effectiveness of intervention measures needs to be further observed.
