Objective To explore the diagnosis and treatment of compartment syndromes of the foot after calcaneal fractures. Methods Between October 1994 and June 1999, the intracompartmental pressures of foot were measured with the Whitesides method for 98 patients with calcaneal fractures. The interstitial pressures in 9 patients averaged 46 mmHg (range from 30 to 55 mmHg). All of the 9 patients were treated by fasciotomy through a hindfoot medial incision, then each intracompartment pressure were measured,respectively. An interosseous compartment pressure still was 40 mmHg. The patient whose foot had a severe crushing injury had fasciotomy of his interosseous compartment through two dorsal forefoot incisions. After a week, the wounds were covered with a split thinkness skin graft. The calcaneal fractures were treated with open reduction and internal fixation at 2 weeks after fasciotomy through a lateral incision. Results All of the 9 patients were followed up for a mean of 2 years (range from 18 to 35 months) after injury. Two patients had occasional hindfoot and ankle pain after walking or standing for a long time. One of them decreased pin stick sensation and two point discrimination. None of the cases developed stiffness of the forefoot or claw toes, nor soft tissue contracture and motor deficit. Conclusion It should not be neglected that the compartment syndromes of the foot may occur after calcaneal fractures. Intracompartment pressure measurements should be performed to confirm the diagnosis. Fasciotomy, which could be performed through a medial hindfoot incision, is the optimal way of treatment.

Objective To investigate the diagnostic values of model of end-stage with incorporation of serum sodium (MELD-Na) score, chronic liver failure-sequential organ failure assessment (CLIF-SOFA) score and APASL-ACLF research consortium score (AARC-ACLF) for evaluation of prognosis of hepatitis B virus related acute-on-chronic liver failure (HBV-ACLF). Methods A total of 72 consecutive patients with HBV-ACLF were included in the study and divided into two groups (group A and group B) according to the prognosis in three-month. Group A were included 29 patients with stable disease or better after medical treatment at least for 3 months, and group B included 43 patients who were dead after treatment or received liver transplantation as failure of medical treatment. When the patients were diagnosed as ACLF or after admission, the data were collected. Results of the laboratory examination were collected when the international normalized ratio (INR) was minimum. Data of total bilirubin (TBIL), prothrombin time (PT), INR, serum creatinine (Cr), serum sodium (Na), albumin (ALB), MELD-Na, CLIF-SOFA and AARC-ACLF scores were calculated respectively. The comparative analysis was performed. Areas under the receiver operating characteristic curve (AUC-ROC) of MELD-Na and CLIF-SOFA scores were used to assess the short-term prognosis in patients with acute-on-chronic liver failure. Results The values of TBIL, INR, MELD-Na, AARC-ACLF and CLIF-SOFA were significantly higher in group B than those in group A (P<0.05). The serum level of Na was significantly lower in group B than that of group A (P<0.05). The area under curve (AUC) values generated by the ROC curves was higher for CLIF-SOFA score (AUC 0.887) than that of MELD-Na score (AUC 0.764) (Z=2.255, P<0.0167). The AUC values generated by the ROC curves showed no significant differences between CLIF-SOFA score and AARC-ACLF score (AUC 0.825) or MELD-Na score and AARC-ACLF score (Z=1.361, 1.127, P>0.0167). The cut-off scores of MELD-Na, CLIF-SOFA and AARC-ACLF were 23.84, 8.50 and 8.50 respectively. Conclusion MELD-Na, CLIF-SOFA and AARC-ACLF scores have appreciable values to evaluate the prognosis in patients with HBV-related ACLF. AARC-ACLF is better than that of MELD-Na and CLIF-SOFA in assessing prognosis of HBV-related ACLF.

Objective To assess the implementation of essential public health services (EPHS), and determine the main influencing factors for EPHS in Menglian. Methods In September 2012, the questionnaire survey method was employed to collect the data of EPHS implementation in 2011 in three community medical institutes and the EPHS evaluation of health staff sampled by stratified random sampling in Menglian. Results In 2011, the report rates of infectious diseases epidemics, public health emergencies and health inspection were all 100%, the inoculation rates of most vaccines were over 90%,and the health management rates of the children aged 0 to 6 years,pregnant and lying-in woman,aged population,hypertensives, type 2 diabetes patients and serious psychotics were high (about 85%) . The establishment rate of heath archives (60%to 70%),the controlling rates of blood pressure in the hypertensive population (about 50%), the rates of glycemic control in type 2 diabetes patients (55%to 70%) and the steady rates of serious psychotics (50% to 60%), however, were low. The implementation of EPHS was unbalance among towns, suburbs and outer suburbs. The main factors that influenced the EPHS implementation were inadequate human resources, insufficient or unused health devices, ambiguous responsibilities among the health institutes, non-cooperative behaviors, and unhealthy living habits in rural residents. Conclusions The implementation of many EPHS items is good. For promoting EPHS,it is necessary to train human resources,activiate unused health devices,get support of residents and carry out health education.

BACKGROUND:Point resolved spectroscopy (PRESS) or single-voxel spectroscopy (SVS) is always used in the previous researches of magnetic resonance spectroscopy (MRS) and its regions of interest are mainly located in focal zones which can be observed with magnetic resonance imaging (MRI); however, both of them cannot manifest the changes of focal marginal zone. Contrarily, hydrogen magnetic resonance spectroscopy (1H-MRS) can det ect the all regions of brain.OBJECTIVE: To observe the 1H-MRS manifestations of patients with heroin spongiform leucoencephalopathy (HSLE) so as to analyze metabolic regularities of N-acetyl aspartate (NAA), creatine (Cr) and bilineurine (Cho) in brain.DESIGN: Case-contrast observation.SETTING: Department of Neurology, Nanfang Hospital.PARTICIPANTS: Three HSLE patients including 2 males and 1 female who were diagnosed with clinical imaging were selected from the Department of Neurology, Nanfang Hospital from August 2005 to August 2006, and all of them were regarded as the case group. In addition, 10 healthy volunteers were regarded as the control group.METHODS: Siemens Megnetom Vision Plus 1.5T superconductive magnetic resonance (MR) system and standard head coil were used in this study, and then, all subjects were checked with 1H-MRS.MAIN OUTCOME MEASURES: Levels of NAA, Cr and Cho in white matter of frontal, parietal and occipital lobes, metabolic maps of them and ratios of NAA/Cr and Cho/Cr.RESULTS: All 13 subjects were involved in the final analysis. ① NAA level: The level of NAA in white matter of frontal,parietal and occipital lobes of case 1 was lower than that of the subjects in the control group (79.50±21.65, 96.75±16.14,77.05±22.47; 146.07±15.49, 117.77±14.56, 120.83±16.02; P < 0.05, 0.01); meanwhile, white matter of parietal lobes of case 2 and case 3 was also lower than that of subjects in the control group (87.50±7.89, 80.65±11.73, P < 0.01). ② Cr level: There were no significant differences of the Cr level of all subjects in both case group and control group (P> 0.05).③ Cho level: Except white matter of frontal lobes in case 1, the level of Cho was lower in the case group than that in the control group (P < 0.01). ④ Ratio of NAA/Cr was lower in the case group than that in the control group, and the radio of Cho/Cr was decreased remarkably. ⑤ Metabolic maps of NAA and Cr manifested a low signal in focal site. ⑥ Ratio of Cho/Cr was obviously reversed in focal marginal zone, but wave of lactic acid was not observed at the same time.CONCLUSION:The area with abnormal metabolites in HSLE patients showed by 1H-MRS is obviously larger than the visible lesion area showed by MRI.There are abnormal metabolites in the adjacent area of HSLE lesions.

OBJECTIVE:To provide reference for the sustainable development of pharmaceutical enterprises in Guizhou prov-ince. METHODS:A questionnaire was conducted for 55 pharmaceutical enterprises in Guizhou province,the basic situation of en-terprises,familiarity of related directors to Good Manufacture Practice of Drugs(GMP)and relevant policy,the current situation of implementing the new version GMP were investigated and statistically analyzed,problems were found,and corresponding coun-termeasures were put forward. RESULTS & CONCLUSIONS:Totally 55 questionnaires were sent out,49 valid ones were received with effectively recovery of 85.1%. The results showed 43 enterprises(87.8%)had passed the GMP authentication;only 13 enter-prises(26.5%)directors were very familiar with the new version GMP. In terms of personnel management,the head of production management and quality management and the authorized person of quality and personnel had not yet met related requirements of the new version GMP fully;in terms of equipment and production management,production area transformation(clean areas,lounges, warehouses,water use) and air purification system design in most enterprises met related requirements of the new version GMP, 23 enterprises (46.9%) still can not conduct fully inspection to products and materials;in terms of document management,there were still some enterprises not meeting the new version GMP standards fully,enterprises'documents(health area layout,air purifi-cation layout,management procedures,operating procedures,etc.) of production site were imperfect. According to the investiga-tion,the main existing problems included lack of funds in implementing the new version GMP reform,not enough understanding or familiarity with the new version GMP,relevant personnel management not reaching the designated position,equipment and pro-duction management needing to be strengthened,document management systemic being poor,risk management being not sound, etc. It is suggested that government should give all forms of capital policy and strengthen the training of the new version GMP;en-terprises should attach great importance to the relevant personnel management,strengthen the equipment and production manage-ment,set up perfect document management system and a sound system of risk management.

Objective To assess the left ventricular (LV) systolic synchrony in patients with myocardial infarction using real-time three dimensional echocardiography(RT-3DE) and speckle tracking imaging(STI). Methods Twenty-five healthy subjects and thirty patients with myocardial infarction underwent two-dimensional echocardiography and RT-3DE examination. The systolic synchrony parameters derived from RT-3DE were the dispersion of time and the maximum difference of time to minimum regional volume for 16 LV segments (Tmsv-16-SD and Tmsv-16-Dif). When the Tmsv-16-SD was above the percent 99 of the control group distribution in patients with myocardial infarction were considered statistically different from those in the control group and were accordingly classified as LV systolic asynchrony. The time from the onset of QRS complexes to systole peak strain from the radial vectors was recorded using STI. The standard deviation and the maximal temporal difference of the radial (TRS-SD and TRS-Dif) of 18 segments were calculated as indicator of LV systolic synchrony. LV systolic asynchrony was defined as an interval≥130 ms for the absolute difference in time to peak radial strain for the anteroseptal wall versus the posterior wall (TAS-POST). Results All the systolic synchrony parameters derived from RT-3DE and STI were significantly larger in the myocardial infarction group than those of the control group (all P<0.01 ).For Tmsv-16-SD and Tmsv-16-Dif,a moderate correlation with TRS-SD and TRS-Dif( r = 0.675 and 0.620,all P<0.01) was found. No significant difference and general consistency were found between the systolic asynchrony parameters by RT-3DE and STI ( P = 0.125, Kappa = 0.60). Conclusions RT-3DE and STI provide effective tools to assess the LV systolic synchrony. There is no obvious correlation between these methods, thus it is essential of using different methods and parameters to evaluate the LV systolic synchrony.
