Objective Measure the variation trend and the problems of bed allocation and its equity at primary medical institutions and provide theoretical basis for optimizing the policy of health resources allocation for the government.Methods Analysis of the distribution and equity of the inpatient beds at primary medical institutions in terms of geographical area by means of the survey of regular overall statistics forms and the methods of Gini coefficient and Theil index.Results From 2009 to 2012,the number increase of beds at such institutions geographically was 7.72%,while that in eastern,central and western regions of China were respectively 5.35%, 3.97% and 27.88%.The number increase at community healthcare centers was 46.58%,while that in eastern,central and western regions of the country were respectively 18.09%,29.57%和 81.53%.The number increase at township hospitals was 2.33%,while that in eastern,central and western regions were respectively - 3.83%,- 0.43% and 22%.The Gini coefficient of bed allocation at such institutions was beyond 0.6,while that in eastern, central and western regions were respectively under 0.3,0.3-0.4 and 0.6 above.The Gini coefficient of bed allocation at community healthcare centers fell from above 0.4 to under 0.4.The Gini coefficient in the western regions increased from 0.3-0.4 to over 0.4.The variation trend of township hospitals was similar with the overall conditions at such institutions.The intra-regional Theil indexes and their contribution rates of bed allocation at such institutions were higher than those of inter-regional. Conclusions The overall variation trend of bed allocation at such institutions was on the rise,yet its variation trend of equity remains unchanged.The bed allocation and its equity at such institutions were higher than those at township hospitals.The growth rate in western regions was the highest,but the absolute number was the lowest.Moreover,the equity of bed allocation in such regions was not only the lowest,but also was found rising.The influence of bed allocation in intra-region terms was large,while its equity was not only lower but falling as well.

Purpose::Under-foot impact loadings can cause serious lower limb injuries in many activities, such as automobile collisions and underbody explosions to military vehicles. The present study aims to compare the biomechanical responses of the mainstream vehicle occupant dummies with the human body lower limb model and analyze their robustness and applicability for assessing lower limb injury risk in underfoot impact loading environments.Methods::The Hybrid III model, the test device for human occupant restraint (THOR) model, and a hybrid human body model with the human active lower limb model were adopted for under-foot impact analysis regarding different impact velocities and initial lower limb postures.Results::The results show that the 2 dummy models have larger peak tibial axial force and higher sensitivity to the impact velocities and initial postures than the human lower limb model. In particular, the Hybrid III dummy model presented extremely larger peak tibial axial forces than the human lower limb model. In the case of minimal difference in tibial axial force, Hybrid III's tibial axial force (7.5 KN) is still 312.5% that of human active lower limb's (2.4 KN). Even with closer peak tibial axial force values, the biomechanical response curve shapes of the THOR model show significant differences from the human lower limb model.Conclusion::Based on the present results, the Hybrid III dummy cannot be used to evaluate the lower limb injury risk in under-foot loading environments. In contrast, potential improvement in ankle biofidelity and related soft tissues of the THOR dummy can be implemented in the future for better applicability.

OBJECTIVETo discuss the impacts of moxibustion for regulating spleen and stomach function on the survival quality of the patients of end stage renal disease (ESRD) with maintenance hemodialysis (MHD).

METHODSOne hundred and nine cases of uremia with MHD from 3 hemodialysis centers were randomized into an observation group (58 cases) and a control group (51 cases). The regular hemodialysis and conventional medication were used in the two groups. In the observation group, on the basis of the common treatment, moxibustion was applied to Zusanli (ST 36) and Sanyinjiao (SP 6), 2-3 times a day, the treatment of 4 weeks made one session. Totally, 3 sessions were required and the follow-up lasted for 3 months. KDQOL-SF (kidney disease quality of life short form,KDQOL-SFTM 1. 3) was adopted for the questionnaire investigation on survival quality before treatment, after treatment and at the end of follow-up separately in the two groups.

RESULTSAfter treatment, the survival quality scores in terms of physical functioning (83.62+/-13.27 vs 79.32+/- 22. 17), general health (58. 88+/- 20.24 vs 48.82+/-20.89) and vitality (77.07+/-15.56 vs 70. 59+/-22.61) in the observation group were higher than those in the control group (all P<0. 05). In comparison before and after treatment in the same group, the survival quality scores in terms of physical functioning, general health, vitality and symptoms/problems were all improved in the observation group (all P<0. 05). At the end of follow-up, the survival quality scores in terms of physical functioning, general health, mental health, social functioning, vitality, effects of kidney disease and cognitive function were higher in the observation group as compared with those in the control group (all P<0. 05). In comparison of the results at the end of follow-up with those before treatment, the survival quality scores in terms of vitality, symptoms/problems and cognitive function in the observation group were improved (all P< 0. 05). The differences were not significant in all of the 19 fields of survival quality evaluation before and after treatment, and after follow-up in the control group (all P>0. 05).

CONCLUSIONMoxibustion for regulating spleen and stomach function improves the survival quality of the patients with hemodialysis in terms of physical functioning, general health and vitality, which benefits the psychological condition of the patients, resulting in the improvements of the survival quality in the fields of mental health, social functioning, effects of kidney disease and cognitive function.

OBJECTIVETo explore the effective therapy for maintenance hemodialysis patients in dificiency syndrome in end-stage renal disease.

METHODSNinety-seven cases were divided into an observation group (51 cases) and a control group (46 cases) randomly, and routine western medicine was used in both of them. On this base, moxibustion was used in Zusanli (ST 36) and Sanyinjiao (SP 6) in paper-tube-moxibustion equipment in the observation group. Evaluate the therapeutic effect on symptoms by comparing the symptom scores in two groups before and after treatment.

RESULTSAll the symptom scores in the observation group were improved after treatment, and the differences were significant (all P < 0.05). Among all symptoms, the most improved ones included lassitude and fatigue, short breath and aversion to talk, poor appetite, soreness and softness of waist and knees, aversion to cold, cold extremities and so on. In the aspect of therapeutic effect on symptoms, the total effective rate in observation group (64.7%, 33/51) was higher than that in control group (23.9%, 11/46), and the difference was significant (P < 0.05).

CONCLUSIONMoxibustion can improve the clinical symptoms of maintenance hemodialysis patients in end-stage renal disease, and can generate some therapeutic effect to the dificiency syndrome of this disease.

Objective By studying biomechanical responses of the femur-prosthesis-tibia complex under normal standing condition after tumor-type hinged knee arthroplasty, to investigate the cause of femoral perforation in patients after knee arthroplasty, so as to provide a theoretical basis for optimal design and manufacturing of tumor-type hinged artificial knee prosthesis. Methods By coupling CT and 3D optical scanning, the finite element model of the subject-specific femur-prosthesis-tibia complex was established and was validated regarding its availability, so as to analyze stress distribution and stress shielding phenomenon of the complex in standing position. Results (1) Under the loading state of standing, the stress on the femur was significantly larger than that on the tibia, and presented an evident concentration phenomenon. The proximal 1/3 of femoral shaft presented a larger stress, with a stress shielding effect. (2) As the model was based on geometry and bone characteristics of the patient in clinic, the location of femur stress concentration was close to that of femur perforation in the patient, which indicated that femur injury behavior might occur when its own gravity was applied such as the patient condition. Conclusions After implantation of the tumor-type hinged artificial knee prosthesis, the prosthesis marrow needle goes deep into marrow cavities, which brings certain pressure to the marrow cavities even under normal standing condition. The produced stress shielding effect and the match of the prosthesis marrow needle to the marrow cavity are all likely to cause stress concentration on the femur, even make femur crack or perforation, and eventually affect the surgery quality. Thus, the prosthesis design should be carefully optimized before surgery in order to reduce or avoid such phenomenon that is related to the postoperative complication rate.

OBJECTIVETo design ABC damage variable and positioning system for acetabular fracture and explore the feasibility and clinical practical value of the system through the multi-center analysis of 1122 acetabular fractures.

METHODSAccording to acetabular three-column conception, and pelvic ring lesions damage direction caused by acetabular fracture domino effect and injury degree of proximal femur joint, it defined class A as any column acetabular fracture; class B as any two-column acetabular fracture; class C as front, dome and posterior mixture acetabular fracture. Lower case English letters a, m, p represented front, dome, posterior fracture, respectively. Acetabular damage variables: 1 was simple displaced fractures; 2 was comminuted fractures; 3 was compression fractures. Pelvic ring lesions damage variables: alpha was sacroiliac joints or sacroiliac fracture horizontal separation deflection; beta was sacroiliac joints or sacroiliac fracture vertical separation deflection; gamma was pubic symphysis separation/superior and inferior ramus of pubis fracture deflection; alpha beta gamma delta was compound floating damage. Proximal humerus joint damage variables: I was femoral head fracture; II was femoral neck fracture; II was intertrochanteric fractures of femur; IV was I to III compound fracture. The ABC damage variable positioning system for acetabular fracture was made up by the above-mentioned variables. The statistics from March 1997 to February 2010 showed 1122 cases acetabular fractures with 18 cases of double side acetabular fracture and 1140 cases of acetabular fractures. The pelvics anterior-posterior view, ilium and obturator oblique view, and 2/3D-CT materials were analyzed and researched.

RESULTSEach damage variables distribution situation in 1140 cases of acetabular fracture involved A in 237 cases (20.8%), B in 605 cases (53.1%), C in 298 cases (26.1%);front column fracture in 808 cases(70.9%), dome fracture in 507 cases (44.5%), posterior fracture in 1026 cases (90%). Acetabular variables: variabe 1 in 203 cases of simple displaced fracture (17.8%); variabe 2 in 516 cases of comminuted fracture(45.3%); variabe 3 in 421 cases of compression fracture (36.9%); 249 cases of pelvic ring lesions damage (21.8%), 75 cases femoral head fracture (6.6%); 18 cases of double side acetabular fracture and relative pelvic ring and proximal humerus joint variables (1.58%). Key part and curative effect elements of 1140 cases acetabular fracture: 507 cases of dome or posterior acetabular fracture (44.5%); 421 cases of compression fracture (36.9%); 249 cases of pelvic ring variables (21.8%); 75 cases of proximal humerus joint variables (6.6%); 486 cases of simple Aa/pl/2,Bapl/2 acetabular fracture (42.6% ).

CONCLUSIONCompression fracture, especially defected compression fracture, takes important part in acetabular damage variables, and also presents that acetabular fracture with pelvic ring and proximal femoral damage variables are not rare at all. The relationship of the acetabular fracture damage variables, and its percentage shows the key points and elements in clinical treatment: weight-bearing to dome accounts for 44.5%; compression to defects account for 36.9%, pelvic ring to float accounts for 21.8%; dome fracture to double side fracture account for 6.6%. The system has significant guiding effects on clinic in terms of evaluation of injury severity, anatomic localization, difficulty index, alternative strategy, operative approach, effect of treatment,and prognosis. And the most important thing is that the system creates the comparison of damage variables in same type of fracture and the communication of homo-language and explores a new method.

The results of Meta-analysis showed that compared with conventional antibiotic therapy，the group of combination with Tanreqing injection was better than the control group in effective rate and lowering serum c-reactive protein （CRP） level，with statistically significant differences. The results of the publication bias test showed that a developmental bias in the effective rate. Further analysis based on the non-parametric clipping and supplementation method showed stable results of meta-analysis and no impact from potential publication bias. The adverse reactions had no statistically significance. Conclusion:This study shows that Tanreqing injection has a significant effect in treating chronic bronchitis in the elderly，and can reduce the serum CRP level of the patients. Compared with the conventional therapy group，the incidence of adverse reactions is not significantly increased，and the results need further clinical tests.

ObjectiveTo analyze the induction effect of Fusobacterium nucleatum （Fn） on endoplasmic reticulum stress-related proteins Glucose-regulating protein 78（GRP78） and X-box binding protein 1（XBP1） in esophageal squamous cell carcinoma （ESCC）， and to explore its potential mechanism and clinical significance. MethodsESCC cells KYSE150 and KYSE140 were infected with Fn for 12 h， 24 h and 48 h. The oxidative stress indexes （ROS， MDA and SOD） and the expression of GRP78 and XBP1 in each group were detected by oxidative stress index kit and Western blot. The experiment was divided into Fn groups， Fn+siNC1 groups， Fn+siGRP78 groups， Fn+siNC2 groups and Fn+siXBP1 groups； the oxidative stress indexes， paclitaxel （PTX） response efficacy， abilities of proliferation， invasion and metastasis in each group were compared. The infection of Fn and the expression of GRP78 and XBP1 in 234 ESCC and paracancerous tissues were detected by RNA scope and immunohistochemistry. The correlation between each factor and clinicopathological characteristics of patients was analyzed by Chi-square test. The influence of each factor on the survival of patients was compared by Kaplan-meier survival estimate. ResultsCompared with Fn uninfected KYSE150 and KYSE140 cells， the content of ROS and MDA was gradually increased， the activity of SOD was gradually decreased， and the expression of GRP78 and XBP1 was gradually increased in Fn infected groups （12 h， 24 h and 48 h） （P < 0.05）. Compared with Fn groups， Fn+siNC1 groups， and Fn+siNC2 groups， ROS and MDA contents were decreased， SOD activity was increased， PTX response efficacy was enhanced， and abilities of proliferation， invasion and metastasis were decreased in Fn+siGRP78 and Fn+siXBP1 groups （P < 0.05）. The rates of Fn， GRP78 and XBP1 in ESCC tissues were 43.16%， 69.66% and 60.68%， respectively. And the three indexes were significantly consistent （P < 0.05）. The patients with positive Fn infection and high expression of GRP78 and XBP1 were mostly males with a history of smoking and drinking， and the tumor differentiation degree was low， the invasion degree was deep， the lymph node metastasis rate was high， and the clinical stage was mostly stage Ⅲ/Ⅳ. The 5-year survival time of patients with above positive indexes was shortened （P < 0.05）. ConclusionsFn could induce endoplasmic reticulum stress by inducing the high expression of GRP78 and XBP1， and promote the malignant evolution of ESCC.

Objective: To compare the prognosis of transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic valve (BAV) or tricuspid aortic valve (TAV) stenosis. Methods: This was a retrospective study. Patients with symptomatic severe aortic stenosis, who underwent TAVR with follow-up time more than one year in Guangdong Provincial People's Hospital from April 2016 to August 2018, were included. According to aortic CT angiography, the patients were divided into BAV group and TAV group. The primary endpoint was the composite event of all-cause death and stroke, and the secondary endpoints were TAVR-related complications. Incidence of clinical endpoints and parameters derived from echocardiography were compared between the groups, and Kaplan-Meier survival analysis was used to compare the composite event between the two groups. Results: A total of 49 patients were included. The age was (73.6±6.3) years, and 25(51.0%) were male. There were 32 patients in BAV group and 17 in TAV group, the follow-up time was 466 (390, 664) days. The incidence of composite endpoint of death and stroke at one year were comparable in BAV and TAV groups (6.3% (2/32) vs. 5.9% (1/17), P=1.00). Kaplan-Meier curves also showed a similar risk of the composite endpoint(HR=1.03，95%CI 0.09-11.24，Log-rank P=0.98) between two groups. The incidence of all-cause death, stroke, myocardial infarction, severe bleeding, major vascular complications, new-onset atrial fibrillation or atrial flutter, and permanent pacemaker implantation were all similar between the two groups(all P>0.05), and there was no acute kidney injury (stage 2 or 3) in both groups. Echocardiographic parameters at one year were similar between the two groups (all P>0.05). Conclusions: The midterm prognosis of TAVR in patients with BAV and TAV stenosis is similar. Clinical trials of large sample size with long-term follow-up are warranted to verify our findings.
