In light of the medical safety control standards for general hospital appraisal in Zhejiang and the principles followed in designing the standards, the authors put forward some suggestions for medical institutions to improve their medical safety control. ①Medical safety occupies a key position in hospital appraisal standards. Some points are presented for discussion with regard to the criteria for malpractice-caused deduction of marks. ②The focal point of medical safety control lies in prevention. Medical institutions and their staff ought to have a correct understanding of malpractice and try to remove hidden dangers. The directive function of plans for preventing and handling malpractice ought to be brought into full play. In addition, nationally uniform and comprehensive criteria and routines for diagnostic, treatment and nursing procedures ought to be set up speedily. ③ It is imperative to make use of advanced means so as to ensure the smooth, timely and efficient reporting and feedback of medical safety information. ④The idea of service ought to be reinforced and a risk assessment mechanism ought to be set up.

Grounded theory was used to summarize and analyze influencing factors and their mechanism on availability of essential medicine.Four factors which influenced the availability of essential medicine were singled out:defective top design in the essential medicine system,interactions among its policies,deviations in the policy implementation by government agencies,and deficiency of supporting policies for the system.The availability of essential medicine in rural areas was influenced by a variety of factors.The ideas and methods of the grounded theory prove helpful for this study.In the future studies,both qualitative and quantitative study should be made to perfect this model formed by the grounded theory,to identify roadblocks and underlying causes in order to provide evidence for improving availability of essential medicine in rural areas.

Objective To study the different types of medication guidance for community doctors in the context of essential medicine system,and analyze its influencing factors.Methods SPSS 1 9.0 was called into play for statistical analysis of data gathered,and the medication guidance behavior of the doctors were graded on the two dimensions of personal willingness and practical action.With important quadrant method,the medication guidance behavior of such doctors was classified,while the multiple linear regression was used to study the influencing factors.Results Most of the community doctors of the fourteen counties fall into the area of “high willingness and less action”,with only a few falling into the area of the “high willingness and more action”. Major influencing factors of their willingness on medication guide were found to include impacts on job autonomy,attention to essential medicine system, and the forms to improve income.Major factors of the doctors'actions on medication guide include awareness of essential medicines,awareness of essential medicines catalog,and training outcomes. Conclusion The community doctors have high personal willingness for medication guidance related to essential medicines,but only a number of them carried it in their work.Therefore,it is necessary to take actions to strengthen awareness of the doctors for medication guidance and encourage them to carry it out.

Objective To comprehensively evaluate prevention and health care services of community health centers in Shandong province since the ongoing health reform and provide policy basis for development of community health services.Methods To study with rank sum ratio method and important quadrant models.Results Seventy-eight percent of community health centers were appraised as“average”.Overall satisfaction of residents for preventive and health services was 2.66 points.Preventive and health services of community health centers are expected to improve.Conclusion Overall prevention and health services of CHS centers were found less than satisfactory.Prevention and health services of CHS centers in regions a and B were poor,which deserves attention of the government health authorities.The government is expected to take actions to promote development of CHS centers for prevention and health care service.

Objective To analyze rural doctors′ social mentality with the theory of relative deprivation.Methods 642 rural doctors from 225 villages of 1 5 counties in Shandong were selected for a questionnaire survey.The factor analysis method was used to reduce the scale dimension and simplify the scale.Analysis of rural doctors′vertical and horizontal relative deprivation was made based on different reference groups.Results Rural doctors tend to identify themselves with rural teachers and doctors in township hospitals,and 60.0% identify themselves as the low income group.39.9% of them found a higher income,while 33.5% of them found a higher social status.76.3% of them found their social contributions are higher.91.4% of them hold that villagers benefit from the new healthcare reform policies,while 65.9% of them hold themselves as benefiting from such policies.This indicates a low sense of achievement.Conclusions Compared with the reference groups,rural doctors feel an obvious sense of relative deprivation comparing both horizontally and vertically.They hold themselves as underpaid and have little sense of achievement for the policies.In this consideration,the government should increase subsidies to lift pay for rural doctors,and to identify their legitimacy,in order to stabilize these medical workers.

To study performance problems found in China's essential medicine system.The SmithModel of system implementation was called into play in a systematic collation and analysis for the ideal policies,system implementation agencies,target groups and policy environment in its performance,along with relationships among the four factors.The system is found with a number of loopholes as the system itself is highly idealized,its system objectives set inappropriately,problems found with the four factors,and tension and conflicts among these factors.Given these problems found in its performance,it is inappropriate to make drastic changes to avoid instability of the system at its early stage.Government departments in question are advised to comprehensively analyze the four factors and their relationships then taking effective measures to deal with them and the tension,conflict among them.This can ensure effectively implementation of the essential medicine system.

Objective To evaluate the township hospitals'medical service efficiency in Shandong province,and to provide references for the development in township hospitals under the background of the essential medicine system.Methods The method of data envelopment analysis(DEA)was used to analyze the township hospitals' medical service efficiency in Shandong province before and since the implementation of the essential medicine system.Results For the township hospitals in Shandong province in general,their relative efficiency ratio of the medical service efficiency dropped from 66.67% to 53.33% since the implementation of the essential medicine system.In terms of the input and output,the non-DEA effective township hospitals are found with insufficient output as measured by the output indicator,while some input indicators input were found as excessive.Conclusion The low scale efficiency has become the main factor for the low service efficiency of such hospitals since the implementation of the essential medicine system in Shandong province.In order to improve the medical service efficiency,it is important to continue to improve the essential medicine system,increase the medical staff's incentives, improve the fiscal compensation policy,and keep the policy continuity.

Objective To evaluate the efficacy and accuracy of hammering reverse guide wire technique for safe placement of anterior column retrograde intramedullary screw in pelvic and acetabular surgery.Methods From September 2015 to March 2018,46 patients with pelvic or/and acetabular fracture involving the anterior column were treated with hammering reverse guide wire technique for safe placement of anterior column retrograde intramedullary screw at Department of Orthopaedics,Lishui Municipal Central Hospital.They were 28 men and 18 women,aged from 21 to 85 years (mean,55.6 years).There were 34 pelvic ring fractures,9 acetabular fractures and 3 combined pelvic ring and acetabular fractures.After the anterior lateral spine of pubic tuberosity was drilled by a guide pin and drill bit as the entry point,a reverse guide wire was knocked into the bone lightly by a hammer.For each retrograde intramedullary screwing into the acetabular anterior column,we recorded operation time,fluoroscopic frequency,and attempts to establish an acceptable screw pathway by the guide pin.The accuracy of screwing and the quality of fracture reduction were evaluated by imaging examination.For each patient,we recorded fracture union time and complications.Functional recovery of the pelvis and acetabulum was assessed by postoperative physical examination at the last follow-ups.Results The operation time of retrograde intramedullary screwing for the 46 patients averaged 28.9 minutes (from 16 to 55 minutes);the fluoroscopy frequency averaged 16.3 times (from 9 to 35 times);an acceptable screw pathway was established by the first attempt in 43 of the 46 patients (93.5％) and re-established after adjustment of the guide pin in the other 3.Forty patients were followed up for an average of 15.2 months(from 6 to 36 months).Postoperative CT scan and three-dimensional reconstruction showed that all the screws had been placed safely and accurately in the acetabular anterior column.Implant loosening and fracture displacement occurred in one case and lower limb thrombosis in another.No nail breakage,fracture nonunion,incision necrosis or infection,neurovascular injury or femoral head necrosis was observed.All fractures united after an average of 14.7 weeks (from 12 to 18 weeks).According to the Majeed scoring at the last follow-ups,the pelvic and acetabular function was evaluated as excellent in 29 cases,as good in 9,and as fair in 2,giving an excellent and good rate of 95.0％.Conclusion Hammering reverse guide wire technique is an effective method for safe placement of anterior column retrograde intramedullary screw in pelvic and acetabular surgery,because it can increase accuracy of screwing and reduce intraoperative radiation,operation time and incidence of complications though it is simple.

Objective:To explore the relationship between new biomarkers in donor blood and delayed graft function after kidney transplantation and evaluate the clinical value of new biomarkers in the diagnosis of DGF (delayed graft function).Methods:For recipients of donor kidney transplantation from August 2016 to December 2017, blood samples were collected from operations of donor organ resection within 12 hours of the day. Enzyme-linked immunosorbent assay (ELISA) was employed for detecting neutrophil gelatinase-associated lipocalin (NGAL), L-type fatty acid binding protein (L-FABP), kidney injury molecule-1 (KIM-1) and interleukin-18(IL-18). They were divided into DGF and EGF (early graft function) groups according to the diagnosis of DGF. The inter-group differences of four new biomarkers were calculated. Receiver operating characteristic curve (ROC curve) was plotted for finding the best positive cutoff value and the sensitivity and specificity of new donor blood marker for diagnosing delayed graft function were calculated.Results:Among them, 8 had postoperative DGF and 62 had none. The overall incidence of DGF was 11.43%. The serum concentration of NGAL was 521.01±132.84 ng/ml in DGF group versus (299.99±100.03) ng/ml in EGF group ( P<0.001). The ROC curve was plotted. With a NGAL concentration >425.15 ng/ml, the sensitivity and specificity for diagnosing DGF were 87.5% and 90.3% respectively. The area under the curve (AUC) was 0.891. The serum concentration of IL-18 was (14.10±12.36) ng/ml in DGF group and (4.61±1.83) ng/ml in EGF group ( P=0.047). With a IL-18 concentration of >5.345 ng/ml, the sensitivity and specificity for diagnosing DGF were 100% and 64.5% respectively. The AUC was 0.914. No significant inter-group difference existed in serum L-FABP/KIM-1. The sensitivity of donor creatinine in the diagnosis of DGF was 62.5%, specificity 75.8% and AUC 0.692. Conclusions:With an excellent level of sensitivity and specificity, an elevated concentration of NGAL/IL-18 in donor blood is superior to traditional creatinine in the diagnosis of DGF after renal transplantation.

A 11-year old female patient with severe thalassemia, receipt a lentivirus-based cell and gene therapy (CGT) therapy in Shenzhen Children′s Hosptial on July 27th, 2021. At the two follow-up visits after discharge, patient were continuously tested positive for HIV screening through HIV Ag/Ab Combo assay (chemiluminescence Immunoassay), and the viral load results of HIV-1 nucleic acid testing (NAT) were both>5 000 copies/ml. The patient can be diagnosed with HIV infection according to the National Guideline for Detection of HIV/AIDS(2020 Revised Edition). The thorough investigation findings and supplementary experiment results indicated that the false-positive HIV-1 NAT results was caused by cross-reactivity between the target sites detected by conventional HIV-1 NAT reagents and the lentiviral vectors fragments integrated into the genome of patient′s hematopoietic stem/progenitor cells. In conclusion, it is important for laboratories to select appropriate HIV-1 NAT testing platforms which won′t cause cross-reactivity for the testing of samples from patients who have been treated with HIV-derived vectors. It is also recommended to design and develop NAT testing platforms with multiple target regions labeled by different fluorescents for HIV NAT supplementation experiment to reduce the risk of false-positive diagnoses of HIV infection.
