Objective To investigate the process of Stark cesarean section (CS) and analyze its key procedures and patients outcomes in order to understand its advantages and promote its standardization. Methods Elective Stark CS cases were divided into two groups according to time sequence and procedure difference. Group A refered to cases underwent modified approaches before standardization (n=362), and group B refered to cases afterward (n= 302). Duration of operation, time interval from incision to delivery, intraoperative hemorrhage, postoperative flatus time, postoperative morbidity, duration of retained urinary catheter, urinary tract irritation, wound infection, and abdominopelvie adhesion in the second operation were compared between the two groups. Results The average duration of the operations and time interval from incision to delivery in group B, which were (27.7± 10. 8) min and (4.92±1.21) min, respectively, were significantly shorter than those in group A, which were (35.6±15.2) min and (7.81±2. 79) min, respectively (P<0. 05). No significant differences was found with regard to average intraoperative hemorrhage between group A and B [(214.34±62. 1) ml vs (201.54-53.1) ml, P>0.05]. Postoperative flatus time in group B was significantly shorter than that in group A [(16.85±11.8) h vs (25.9±12. 7) h, P<0. 05]. Postoperative morbidity in group B was significantly lower than that in group A [1.3%(4/302) vs 4.7%(17/362), P<0.05]. The average duration of retained urinary catheter in group B was significantly shorter than that in group A [(15.6±5.3)h vs (26. 2±6.1)h, P<0. 05], and the urinary tract irritation rate in group B was also lower than that in group A [2. 5%(9/362) vs 0(0/302), P < 0. 05)], No incisional infection or delayed healing was found in either group. Rectus muscles, fascia and peritoneum adhesions were found in three cases with second surgery in group A and none in group B. No omentum, peritoneum and visceral peritoneum adhesion was found in either group. Conclusions Compared to the modified Stark operation, standardized procedure decreases operation associated complications and improves maternal outcomes. Therefore, standardized Stark CS should be promoted for better operative outcomes.

Objective: To explore diagnostic value of dynamic electrocardiogram (DCG) on coronary artery disease. Methods: A total of 100 inpatients with “angina pectoris” history from our hospital were enrolled and received 24h DCG measurement. The DCG examination results were compared with those of coronary angiography (CAG) and analyzed then. Results: Among the 100 patients, there were 85 patients with positive DCG, including 70 cases with positive CAG and 15 cases with negative CAG; and 15 patients with normal (negative) DCG, including 10 cases with negative CAG and five cases with positive CAG. With CAG as golden standard, sensitivity, specificity, positive predictive value (accuracy) and negative predictive value of DCG in diagnosis of coronary heart disease were 93.3%, 40.0%, 82.4% and 66.7% respectively. Partial patients had “angina pectoris”, no stenosis in CAG but there’s slow blood flow. Conclusion: Dynamic electrocardiography is one of important measuring methods diagnosing coronary heart disease. It is simple, practical, safe, economic and appropriate for wide application in clinic, but its specificity is just 40.0%, so coronary heart disease cannot be excluded in negative patients.

OBJECTIVE:To provide theoretical support for the scientific and reasonable policy-making of 23-valent pneumococ-cal polysaccharide vaccine(PPV-23)in elderly. METHODS:Retrieved from CJFD,Wanfang Database,Elsevier and PubMed,lit-erature about the pharmacoeconomics evaluation of PPV-23 in elder were selected and statistically analyzed in respects of cost stud-ies,effect indexes and research perspectives. RESULTS:Totally 13 literatures were included,involving 900 472 patients,who were older than 60 years old. Study locations were mainly Colombia,the United States,Italy,Belgium and China. Study results showed,each additional quality-adjusted life-year(QALY)cost was between $ 9 239-$ 33 000 in respect of cost;cost-effectiveness ratio was between $ 9 239-$ 45 161/QALY in respect of effect indexes. Most researches showed PPV-23 in elderly older than 65 years old had certain cast-effectiveness. Only a research in Netherlands held the idea that PPV-23 in elderly was not considered cost-effectiveness.CONCLUSIONS:Putting PPV-23 inelderly has certain cost-effecctiveness and most countries has put it into nation-al immunization program. The present researches can't ensure the economy of putting ppv-23 in elderly in china,so it needs more researches with high quality to ensure it.

Objective In this study,the phenotype heterogeneity of 2 male patients with X-linked Alport syndrome from one family was analyzed and the likely reasons were discussed by reviewing the literature.Methods The clinical data at the time of diagnosis and during 5 years follow-up of 2-male patients with X-linked Alport syndrome from one family were collected.The α5 (Ⅳ) chain expression in the epidermal basement membrane was detected by indirect immunofluorescence method.COL4A5 gene mutations in skin fibroblasts and genomic DNA were detected by using reverse transcription polymerase chain reaction and direct sequencing and PCR sequencing methods from skin fibroblasts and genomic DNA,respectively.Results The diagnostic age of patient Ⅲ 1 was 14 years old.He had only microscopic hematuria,and proteinuria was negative.A negative α5 (Ⅳ) chain staining pattern was detected in his epidermal basement membrane.After 5 years follow-up without drug treatment,he was 19 years old,had persistent microscopic hematuria and normal renal function.The urinary microalbumin was 19.2-31.8 mg/L.The diagnosis age of patient Ⅱ 4 was 29 years old.The hematuria and proteinuria were found at 22 years old.He was treated with tripterygium wilfordii for 1 year.His disease progressed to an end stage of renal disease and he received hemodialysis therapy at 24 years old.He had the renal transplantation surgery at 29 years old,just 2 months before he came to hospital.And his renal function was restored.After 5 years follow-up,his urine examination and renal function were normal.Both patients had a missense mutation c.3650G ＞ A(p.G1217D) in exon 41 in COL4A5 gene.Conclusions The different phenotypes of 2 male patients from one family with X-linked Alport syndrome were reported.The most possible reason for this is somatic mosaic variants in COL4A5 gene based on literature review.Physicians should be alert to phenotype heterogeneity in male X-linked Alport syndrome despite having the same gene mutation.

Objective: To evaluate the clinical effectiveness of multi-directional mechanical traction (MT) for the treatment of patients with lumbar disc herniation (LDH) compared with longitudinal traction (LT) as control. Method: This prospective, single-blind, randomized clinical trial was performed in Qi Lu Hospital, Shandong University from January 2008 to December 2008. One hundred and twenty outpatients with LDH were randomly divided into MT group or LT group. MT group was treated with computer-controlled multi-directional mechanical traction.LTgroupwastreatedwithlongitudinaltraction.RolandMorrisLowBackPainandDisability Questionnaire (RMDQ), visual analogue scale (VAS), and straight leg raising (SLR) angle were measured for every patient pre-, 4 weeks post-, and 1 year post-treatment.Result: The results of clinical observations showed significant improvements inRMDQ, VAS, and SLR angle assessments (all P＜0.05) in both groups 4 weeks post- and 1 year post-treatment compared with pre-treatment. Score of RMDQ in MT group was significantly lower than that in LT group(P＜0.05), however, there was no significant difference between two groups in VAS score and SLR angle (P＞0.05). The differences in improvement ratios between two groups were not significant (all P＞0.05). The clinical outcomes were negatively correlated with patient's age and disease duration.Conclusion: The effect of MT is equivalent and probably superior to that of LT in improving the symptoms and clinical findings of patients with LDH.

Objective To investigate the changes of stress responses and fibrinolysis under three anesthesia techniques undergoing elective hysterectomy during perioperative period. Methods Thirty ASA Ⅰ or Ⅱ patients aged 31-57yr weighing 45-70 kg undergoing elective hysterectomy were divided randomly into 3 groups ( n = 10 each): group Ⅰ continuous epidural anesthesia (E); group Ⅱ general anesthesia combined with continuous epidural anesthesia (G + E) and group Ⅲ general anesthesia (G) . The patients in the 3 groups were all premedicated with midazolam 0.05 mg?kg-1 i.v. . In group G and G + E the patients received an additional scopolamine 0.3 mg i.v. . In group E and G + E an epidural catheter was placed through L1-2 interspace and 2% lidocaine 5 ml was given as test dose. The spinal segments blocked was extended from L3 to T6 using 0.75 % bupivacaine. In group G and G + E general anesthesia was induced with fentanyl 2-3 ?g ? kg-1, propofol 1.5-2.0 mg?kg-1 and vecuronium 0.1 mg?kg-1 and maintained with isoflurane inhalation and intermittent i.v. boluses of vecuronium. The patients were mechanically ventilated after tracheal intubation. BIS, ECG, BP, HR, SpO2 , PETCO2 and end-tidal isoflurane concentration were continuously monitored during operation. BIS value was maintained below 60. PCEA or PCIA was started as soon as the patients were awake. VAS scores were maintained below 3-4. Venous blood samples were taken before anesthesia (T0 baseline) at the end of operation (T1) and 24 and 72 h after operation (T2 , T3) for determination of plasma adrenaline (A) and noradrenaline (NA), D-dimer level (DD), tissue type plasminogen activator (t-PA ) and plasminogen activator inhibitor ( PAI-1) concentrations. Results The plasma NA and A concentrations in group G were significantly increased at T1-3 as compared to the baseline value at T0 and were significantly higher than those in group E and G + E. There was no significant difference in plasma NA concentration between group E and G + E. The DD level was significantly increased at T2 as compared to the baseline value at T0 in all 3 groups and remained high at T3 in group E and G + E. The t-PA and PAI-1 activities were significantly increased at T1 as compared to the baseline values at T0 in all three groups and then gradually decreasing at T2 and T3 . In group E the PAI-1 activity returned to baseline level at T3 . Conclusion Epidural anesthesia helps in maintaining fibrinolytic activity by attenuating the responses to surgical stress and inhibiting the increase in PAI-1 activity.
