Health appropriate technologies are applied nationwide in our country and have produced good results. But the informatization of health appropriate technologies lags behind and is still at a preliminary stage.As the network of Zhejiang basic health appropriate technologies has been estabished,this paper discusses some issues related with the informatization of health appropriate technologies.

Objective To access the changes of lung function of newborns with pneumonia and to investigate the feasibility of measuring lung function in the body plcthysmograph for diagnosing and treating respiratory diseases.Methods There were 117 infants,1 day after being diagnosed with mild or moderate pneumonia,aged 4-28 days,involved in the study,those who needed oxygen cure,mechanical ventilation,or had complications from pneumonia were ruled out.Pulmonary function tests (PFTs) were performed in the baby body plethysmography to access tidal breathing,plethysmographic functional residual capacity (FRCp),and effective airway resistance (Reff).The other 126 contemporaneous healthy children took the same test for comparison.According to their ages,infants were grouped into 4-7 d,8-14 d,15-21 d and 22-28 d.Results Of the 117 infants with pneumonia,79 (67.5 ％ equivalently) had abnormal lung function.Compared with the controls,infants with pneumonia had significantly higher values of peak tidal expiratory flow [(59.4 ± 16.6) mL/s vs (52.9 ± 16.6) mL/s],expiratory flow at 75％ tidal volume [(57.4 ± 16.7) mL/s vs (49.5 ± 16.7) mL/s],special effective airway resistance (0.48 kPa · s vs O.27 kPa · s),Reff [6.96 kPa · s/L vs 4.82 kPa · s/L] and Reff per kilogram [1.99 kPa · s/(L · kg) vs 1.44 kPa · s/(L · kg)],but lower values of time to peak tidal expiratory flow as a percentage of total expiratory time [(26.5 ± 10.0) ％ vs (36.8 ± 9.9) ％],volume to peak tidal expiratory flow as a percentage of total expiratory volune [(27.9 ± 7.3) ％ vs (35.6 ± 8.4) ％]and expiratory flow at 25％ tidal volume [(36.3 ± 11.7) mL/s vs (40.1 ± 12.4) mL/s].There were no sig± nificant differences in the values of respiratory rate,FRCp and FRCp/kg between the pneumonia children and the healthy control chidren.Compared with the infants aged ≤ 14 days,there were more significant differences in relative parameters of lung funetion between the pneumonia group and the healthy control group for infants aged 15-28 days.Conclusions Newborns with pneumonia had a high ratio of abnormal lung function,which went up to 67.5％,and had apparent obstruction of small airways.Neonates with pneumonia aged 15-28 days had more apparent lesion of lang function.Measuring lang function by means of plethysmography among newborns is feasible and it can detect abnormal lung function sensitively.

Shanghai district and county health system performance evaluation conceptual frameworkwas proposed based on health services system performance assessment frameworks raised by some countries and international organizations,and combined with Shanghai district and county health system characteristics.This framework contains two first grade indices and seven second grade indices:In the long term goals,'health','satisfaction' and 'disease risk protection' are the county's longterm effects of health system performance assessment dimensions; in the medium-term goals,the'accessibility','cost',' efficiency' and 'quality' are the county' s medium-term effects of health system performance assessment dimensions.This study aimed to evaluate Shanghai county health system's overall performance.Further study is needed in constructing its third grade indices.

Objective: To assess trends of β-blocker use within 24h of admission in ideal candidates with acute myocardial infarction (AMI) in eastern urban China from 2001 to 2011. Method: A 2-stage random sampling design was performed. In the first stage, a simple random-sampling was used to identify participating hospitals. In the second stage, a systematic sampling was conducted in 2001, 2006 and 2011 to select cases from the participating hospitals. Data was obtained by central medical record abstraction. 10-year trend and predictors of early β-blocker application were assessed with weighted calculation for each year to represent the overall situation of eastern urban China. Results: 35 hospitals were sampled and 32 of them were finally participated. With necessary exclusion, 1399 ideal candidates were included in this analysis. The early weighted β-blocker application rates in 2001, 2006 and 2011 were 64.7%, 69.7%, and 60.9% respectively, P=0.0447 for trend. Patients with chest pain at admission (OR=2.22, 95% CI 1.19-4.13), higher systolic blood pressure (OR=1.40, 95% CI 1.11-1.77) or faster heart rate (OR=2.01, 95% CI 1.58-2.55) were more likely to use β-blocker; in contrast, compared with NSTEMI patients, STEMI patients seemed less likely to receive such treatment (OR=0.55, 95% CI 0.37-0.81). Conclusion: The early β-blocker therapy in eastern urban China is suboptimal for ideal AMI patients who could benefit from it. The application pattern has not been changed from 2001 to 2011 which might be related to physicians' misunderstanding of relevant evidence or guidelines. Our study may help to create an important target to improve the quality of AMI care.

BACKGROUND: Artificial humeral head replacement is an effective method for the treatment of complex proximal humeral fractures, which has received good results in relieving pain. However, the final functional recovery is unpredictable. OBJECTIVE: To compare biomeshanical stability between anatomical and overlapping reconstruction of the greater tuberosity in cadaveric humeral head replacement models.METHODS: Eight pairs of fresh-frozen shoulder cadavers (16 shoulder joints) were match-paired into two groups. Standardized humeral head replacement procedure was performed in all specimens, and anatomical and overlapping reconstruction of thegreater tuberosity was adopted in each group respectively. For overlapping group, the greater tuberosity was reattached to the proximal humeral shaft in an overlapping style, which was achieved by an additional 5 mm bone osteotomized from the medial cortex of the humeral diaphysis. Custom mounting apparatus and fixation jigs were designed for designated shoulder motion.RESULTS AND CONCLUSION: When the shoulder was external rotated to neutral position, the mean displacement of greater tuberosity in the anatomical reconstruction group was smaller than that of the overlapping reconstruction group (P < 0.05). When the gleno-humeral joint was elevated to 30～ and 60～ forward flexion (accounting for 45° and 90° shoulder forward flexion), there was no significant difference of greater tuberosity displacement between the anatomical group and overlapping group. The findings demonstrated that, although overlapping reconstruction can increase the bone healing area between the greater tuberosity and the humeral diaphysis, there may be some loss in mechanical stability as the trade-off. Even though we strictly follow the standardized postoperative rehabilitation protocol after humeral head replacement, prominent displacement between the greater tuberosity relative to the humeral diaphysis was detected. Accordingly, postponing of the postoperative rehabilitation program after humeral head replacement for a decent period may improve tuberosity healing.

Objective:To evaluate the performance of RapidArc technique on cervical cancer patients with various filling status of the bladder. Methods: Conventional fixed field intensity modulation radiated therapy (IMRT) is used as the benchmark. In 10 fe-males suffering from cervical cancer, two CT scans were performed for treatment planning:one with an empty bladder and the other with filled bladder. The prescribed dose was 50 Gy. The images of that with an evacuated bladder and that with filled bladder were planned in the dual-arc RapidArc and the 7-field IMRT, respectively. The implementor of the plan was the Varian TrueBeam linear ac-celerator. Dose-volume histogram was used to evaluate the data from each plan. Results:When the bladder was filled, IMRT and Rapi-dArc homogeneity were 1.05 and 1.04 (P>0.05), respectively. When the bladder was emptied, the homogeneity was 1.04 for both plans (P>0.05). With or without bladder filling, the conformity index was 0.71 and 0.73 for IMRT and RapidArc (P>0.05), respectively. The effect of V30 and V40 (volume for receiving doses of 30 and 40 Gy) on the intestine and the bladder was more favorable in a full than in an empty bladder. No significant difference between the two plans was observed. IMRT exhibited improved V30 on the rectum and on the bladder. RapidArc was much better in terms of monitor unit (MU) and deliver time. Conclusion:No significant differences in the homogeneity and conformity index between dual-arc RapidArc and 7-field IMRT were observed. Filled bladder is better than empty bladder in intestine and bladder protection in both RapidArc and IMRT. IMRT is better on V30 of the rectum and the bladder, whereas RapidArc improved MU and deliver time.

Objective To compare the clinical efficacy and radiologic changes between constrained and non-constrained titanium plate in anterior cervical corpectomy and fusion (ACCF) in elderly cervical spondylosis patients.Methods A total of 58 elderly cervical spondylosis patients who underwent ACCF were divided into group 1 (patients treated with constrained titanium plates,n =30) and group 2 (patients treated with non-constrained titanium plates,n=28).The Japanese Orthopedic Association (JOA) score,fusion rate,the loss of segmental height and cervical lordosis were recorded.The clinical efficacy and imaging features were compared between the two groups.Results The improvement rate of JOA score had no significant differences between group 1 and group 2 [(77.7±18.6)％ vs.(75.8±23.2)％,t=0.340,P＞0.05].At 3 months after operation,the fusion rate was higher in group 2 than in group 1 (89.3％ vs.63.3％,x2 =5.327,P＜0.05).At 3,6 and 12 months after operation,there were no significant differences in the loss of segmental cervical height and lordosis between group 1 and group 2 [(2.42±3.05)mm vs.(0.98±2.86)mm,(3.95±3.65)mm vs.(2.34±2.97)mm,(3.60±4.33)mm vs.(2.40±2.96)mm,(1.64±2.33)° vs.(0.66 ± ±2.14)°,(2.13∧±±3.79)° vs.(0.70±2.99)°,(2.39±4.26)° vs.(0.86±3.25)°,respectively,all P ＞0.05].Conclusions The clinical efficacy is similar in ACCF with the two types of titanium plates.The non-constrained titanium plate can increase the fusion rate in early time,but may aggravate the loss of segmental cervical height and lordosis,which should be used with caution in elderly osteoporosis patients.

Objective To understand the status of Toxoplasma gondii infection in the population of Pu er City so as to pro-vide the evidence for formulating the strategy of toxoplasmosis control. Methods The population from Jingdong Jinggu and Menglian counties in Pu er City was surveyed IgG of T. gondii in serum was detected by ELISA. Results Totally 906 resident serum samples were detected and the IgG positive rate was 24.2%. The positive rates were higher in the aged groups of 30-39 years and 60-69 years and the difference among different aged groups was significant χ2=17.77 P 0.01 . There were no si-gnificant differences between different sexualities and among different educational levels and living habits P 0.05 . The posi-tive rates were 26.6% 194/730 15.5% 22/142 and 8.8% 3/34 in farmers students and other occupations respectively and there was a significant difference among them χ2=12.51 P 0.01 . The positive rates were 23.3% 198/849 and 36.8%21/57 in the farmers who had the habit of rearing pigs in pens and the farmers who had the habit of free ranging pigs respec-tively and there was a significant difference between them χ2=5.33 P 0.05 . Conclusion The IgG positive rate of T. go-ndii is very high in Pu er City and therefore the health education for toxoplasmosis control should be strengthened.

Background Elevated intraocular pressure leads to the loss of retinal ganglion cells and vigorous reaction of retinal glial cells.The expression of nestin in retinal glial cells secondary to hypertention and its significance are unclear.ObjectiveThis study aim to investigate the expression of nestin in retinal glial cells (RGCs) in ocular hypertention rats.Methods The ocular hypertention models were established by cauterizing the limbus-draining veins in the right eyes of 42 SD rats,and a conjunctival incision in the left eyes of the rats served as the sham group.The intraocular pressure (IOP) was measured with the Tono-Pen XL tonometer.The number of RGCs in the rats with ocular hypertention was counted.The expression of the nestin protein in RGCs was semi-quantitatively analyzed using Western by immunochemistry.Double immunofluorescence was carried out to evaluate the the confocal laser scaning microscope.Results Significant differences were found in the IOP between the model group and the sham group at various time points (P＜0.05).In 1 week to 3 weeks after operation,the number of RGCs significantly declined in the model group compared with the sham group (P＜0.05).Immunochemistry showed that from 2 hours through 1 week after operation,the expression of nestin was gradually enhanced in the model group in comparison with the sham group.Western blot revealed that the expression of the nestin protein reflected a similar tendency to that of immunofluorescence.The increased introcular pressure as manifested by the induced expression of nestin.Immunoelectron microscopy also confirmed the induced expression of nestin especially at their end-feet suggests a potential neuroprotective mechanism in neuronal degeneration.Nestin may be a useful biomarker for retinal injury study.
