OBJECTIVE:To observe therapeutic efficacy and safety of Zhenqi fuzheng granules in the adjunctive treatment of cervical cancer. METHODS:86 patients with cervical cancer were randomly divided into control group(43 cases)and observation group (43 cases). Control group was given intravenous dripping of Diphenhydramine hydrochloride injection 20 mg,Granisetron hydrochloride and glucose injection 5 mg,Cimetidine injection 20 mg at 0.5 h before chemotherapy. After 0.5 h of intravenous drip-ping,the patients received chemotherapy:Docetaxel injection 40 mg/m2,d1,d8,intravenous dripping;Cisplatin for injection 25 mg/m2,d1-3,intravenous dripping;21 d as a cycle,a total of 4-6 cycles. On the basis of control group,observation group was addi-tionally given Zhenqi fuzheng granules 5 g,twice 2 day. Clinical efficacies of 2 groups were observed as well as T cell subsets in-dexes [CD3+,CD4+,CD8+,natural killer cell(NK)],KPS scores,termination,terminal time,the times of chemotherapy and the oc-currence of toxic reaction before and after treatment. RESULTS:The total remission rate of observation group was significantly higher than that of control group;the proportion of termination of chemotherapy in observation group was significantly lower than control group;terminal time of chemotherapy was significantly shorter than control group;the times of chemotherapy was signifi-cantly more than control group;the incidence of gastrointestinal reaction,anemia,thrombocytopenia and leukopenia were signifi-cantly lower than control group,with statistical significance(P<0.05). There was no statistical significance in liver function dam-age,renal function injury and stomatitis between 2 groups (P>0.05). Before treatment,there was no statistical significance in T cell subsets indexes and KPS scores between 2 groups(P>0.05). After treatment,CD3+,CD4+ and NK cells in observation group were significantly higher than before treatment and control group,while CD8+ was significantly lower than before treatment and control group;KPS scores of 2 groups were significantly higher than before,and the observation group was significantly higher than the control group,with statistical significance(P<0.05). There was no statistical significance in T cell subsets indexes of con-trol group before and after treatment(P>0.05). CONCLUSIONS:On the basis of routine treatment,Zhenqi fuzheng granules can improve therapeutic efficacy,immune function and the quality of life,moreover,reduce toxic reaction in patients with cervical can-cer.

Objective To investigate the long-term effects and risk factors of arterial polyvinyl alcohol resin (PVA) embolization for ⅢB and IV non-small cell lung cancer(NSCLC) patient.Methods 126 patients with 1 B or V NSCLC were performed the perfusion with 5-FU,THP,DDP by PVA grain embolization under fluoroscopic control.All patients were followed up.Kaplan-Meier was used to calculate the survival rate and the median survival time,and Cox regression model was adopted to analyze related risk factors which affected curative effect.Results The median survival time was( 11.78 ± 3.24) months and 1 -,2-year survival rate was 39.1 ％,25.59％ in 126 patients with NSCLC.Cox model analysis showed that of the tumor staging,tumor size,location and combination chemotherapy were all independent risk factors of prognosis (all P ＜ 0.01 ).Conclusion Arterial embolization of PVA for treatment of NSCLC is effective.Tumor size,stage,location and combination chemotherapy are associated with prognosis of NSCLC.

The overall skin ulceration area was accounted for 13% of total body surface area. We chose different dressings, combination anti-infection with promoting wound healing for nursing and achieved great effect. The skin lesions gradually healed and the patient went to the general ward successfully.

BACKGROUNDTobacco-specific 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) is the most important carcinogen in cigarette. Models induced by NNK are widely used in investigations about the mechanisms of pulmonary neoplasia and chemoprevention studies. The aim of this study is to explore the pulmonary precancerous lesions induced by NNK and its possible mechanisms.

METHODSFifteen Wistar rats were divided into two trial groups, in which the high-dose group was instilled with iodized oil including 10 mg (50 mg/kg) NNK into the left lower lobar bronchus, and the low-dose group received 5mg ( 25mg/kg) NNK. Another 15 Wistar rats were instilled only with iodized oil as control group. All rats were examined immediately after instillation and followed up periodically by pulmogram. The pulmonary tissues of rats were pathologically examined, and the expression of AE1/AE3, PCNA and p53 was detected by immunohistochemical method.

RESULTSThe pulmograms showed that the iodized oil localized at the bottom of left lobe and disappeared 107 days later. In trial group, 10 of 15 rats (67%) had nodus at the bottom of left lobe. All of rats in trial group (15/15) displayed atypical hyperplasia in alveolar region, showing single or multiple layers of proliferative epithelial cells along intact alveolar septa with irregular and non-discrete margins of lesion, but continuous alveolar spaces were not obliterated by proliferative epithelial cells. Ten of 15 rats in trial group showed severe atypical hyperplasia of glandular epithelium with occasional infiltrating to muscular layer. All of those atypical hyperplasia cells showed positive AE1/AE3 expression. The positive rate of PCNA was 90% (9/10) and 100% (5/5) in low-dose group and high-dose group respectively, which was significantly higher than that in control group (13%, 2/15) (P=0.000, P=0.001). The positive rate of p53 expression was 50% (5/10) and 60% (3/5) in low-dose group and high-dose group respectively, which was significantly higher than that in control group (0) (P=0.005, P=0.009). However, there was no remarkable difference in PCNA and p53 expression between low-dose group and high-dose group (P > 0.05).

CONCLUSIONSTransbronchial instillation of iodized oil including tobacco-specific NNK can induce pulmonary lesions as atypical hyperplasia of alveolar cell and glandular epithelium in Wistar rats. This model can be used in experimental studies about tobacco-related lung cancer.

Objective:To evaluate the feasibility of placement of S 2 alar iliac screw (S 2AI) using free-hand technique for sacrapelvic fusion in lumbar degenerative scoliosis. Methods:Eighteen patients with Lumbar Degenerative Scoliosis treated by S 2AI screw fixation at Department of Orthopedics, General Hospital of Southern Theater Command of People′s Liberation Army and Department of Orthopedics, 89th hospital of People′s Liberation Army from August 2014 to October 2018 were analyzed retrospectively. There were 5 males and 13 females, aged 63.2 years old (range:55 to 71 years old).Parameters of spine including: Cobb Angle, C 7 plumb line -center sacral vertical line (C 7PL-CSVL), lumbar lordosis(LL), sagittal vertical axis(SVA), pelvic incidence(PI), pelvic tilt(PT), sacral slope (SS) and pI-LL were measured on the whole spine X-ray before operation and at final follow-up. Pelvic CT scan was performed postoperatively to assess the accuracy of S 2AI placement. Oswestry disability Index (ODI) was also recorded. The data were compared by paired t test or Wilcoxon tests.

Objective To investigate the changes of prevalence of hyperuricemia ( HUA) and its correlations with blood glucose and lipid in healthy adults receiving physical examination at Peking Union Medical College Hospital (PUMCH) from 2012 to 2017. Meth-ods An observational approach was adopted for the data analysis.The test results of uric acid (UA),fasting blood glucose (FBG),to-tal cholesterol (TC),triacylglycerol (TG),low density lipoprotein cholesterol (LDL-C),high density lipoprotein cholesterol (HDL-C), creatinine (Cr) and Urea of 399 089 cases (206 881 males and 192 208 females) at PUMCH from January 2012 to December 2017 were collected and statistically analyzed.Results The total prevalence of HUA was 17.4% in which the prevalence of males was signif-icantly higher than that of females (25.6% vs 8.5%,χ2＝20 234.850,P＜0.01).During the years of 2012 to 2017,the prevalence of HUA was 26.5%,24.7%,28.6%,23.9%,24.8% and 24.5% in males,and 13.8%,6.3%,7.9%,6.1%,6.2% and 6.8% in females for each year respectively.The prevalence of HUA in males aged 18 to 64 years old was significantly higher than that in the age-matched fe-males (all P＜0.05).However, the prevalence of HUA in males aged≥65 years old was similar to the age-matched females.There was no statistically significant difference of HUA prevalence between males and females aged ≥65 in 2013,2015,2016 and 2017 ( χ2＝1.792,0.017,1.440 and 0.205 respectively;all P＞0.05).The percentages of hyperlipidemia in both males and females of HUA group were higher than those of non-HUA group respectively (all P＜0.01).The percentage of hyperglycemia in males of non-HUA group was higher than that of HUA group,but the percentage of hyperglycemia in females of non-HUA group was lower than that of HUA group ( all P＜0.01).High levels of TC,TG and FBG were risk factors of HUA with increased OR values in increased concentrations of TC,TG and FBG,respectively.Conclusion During the recent 6 years, in healthy adults receiving physiced examination at PVMCH, the preva-lence of male HUA diagnosed was at overall high level,but the prevalence of female HUA was in decreasing and relatively stable trend. Hyperlipidemia and hyperglycemia should be the risk factors of HUA.

The authors described the attempt of general practice in hierarchical medical system aided by the medical service partnership model.This reform has achieved an effective and efficient hierarchical medical system for chronic diseases within a medical alliance, overcoming the existing hierarchical medical system centering on a hospital.Other merits of the reform include a general practice guidance pattern between general hospitals and community hospitals and enhanced general practitioner competence in communities,effectively encouraging general practice progress.

Objective:To report our experience in diagnosis and treatment of posterior atlantoaxial dislocation with odontoid retrolisthesis.Methods:A retrospective study was conducted of the 5 patients who had been treated from July 2012 to August 2018 at Department of Orthopaedics, General Hospital of Southern Theater Command for posterior atlantoaxial dislocation. They were 4 men and one woman, aged from 34 to 67 years (average, 47 years). All of them had a history of trauma. Of them, 4 were complicated with odontoid fracture and one with congenital free os odontoideum. Their posterior atlantoaxial dislocation ranged from 3 to 9 mm (average, 6 mm). By the American Spinal Injury Association (ASIA) grading system, their preoperative spinal injury was rated as grade B in one, as grade C in 3 cases and as grade D in one. All the 5 patients underwent skull traction at 10° flexion. Surgical trans-oralpharyngeal atlantoaxial reduction and internal fixation was performed for the one patient whose reduction had not been achieved by traction while posterior atlantoaxial screw-rod fixation or anterior odontoid screwing was conducted for the 4 patients whose reduction had been achieved by traction. The distance of posterior atlantoaxial dislocation was measured to evaluate their reduction and ASIA grade system was used to assess their spinal function after operation.Results:The postoperative distance of posterior atlantoaxial dislocation was 0 mm, showing a reduction rate of 100%. The 5 patients were followed up for 6 to 36 months (average, 15 months). By the ASIA grade system, the postoperative functional recovery of the spine was grade D in 4 cases and grade C in one. No implant loosening or breakage occurred.Conclusion:As a kind of high-energy hyperextension injury, posterior atlantoaxial dislocation is rare in clinic, but an appropriate treatment can be adopted to deal with its different clinical types to achieve good outcomes.

Objective To evaluate the analytical performance of four lipoprotein associated phospholipase A2(Lp-PLA2)activity reagents on Beckman AU5800 automatic biochemical analyzer. Methods The remaining serum samples of 214 patients and 140 apparently healthy individuals were collected from March to July 2017 in Peking Union Medical College Hospital.These samples were used for method comparison and reference interval evaluation.According to the guidelines of EP15-A,EP6-A,EP-17 and EP7-P from Clinical and Laboratory Standards Institute(CLSI)standards,the precision, linearity, sensitivity and common interferences(e.g free bilirubin, conjunct bilirubin, hemoglobin and chyle)were assessed.According to EP9-A2,method comparisons of differents regents(Evermed,DiaSys,Hengxiao and Zhongyuan were labeled as A,B,C and D,respectively)were conducted and the differences were estimated at medical decision levels(328U/L,391U/L and 485U/L).Results The precision of four reagents were acceptable.The repeatability(CV%)of A to D were 0.5%-1.7%, 0.7%-3.0%, 0.9%-2.0% and 0.5%-3.3%,respectively.The reproducibility(CV%)were 0.7%-2.9%, 1.4%-3.2%, 1.3%-1.9%and 0.8%-4.1%,respectively.Both of those achievedlaboratory defined quality objective(<5%).The linearity of A to D were 44 -1 992 U/L,39 -1 798 U/L,13 -540 U/L and 75-1 717U/L,respectively.The regression coefficient R2 was between 0.997 and 1.000, and the correlation coefficient(r)was between 0.998 and 1.000.The interference of chyle were acceptable among these four reagents andmet the manufacturer′s requirementsor clinical needs.In a low level of Lp-PLA2,bilirubin had an obvious interferenceonreagent C;B and C were negatively affected when the hemoglobin was 4.5 g/L; and D was positively affected when the hemoglobin was 2.45 g/L.The regression coefficients R2 of A,C,D compared with B were between 0.978 and 0.995,and the correlation coefficients(r)were between 0.989 and 0.998. The expected differences at medical decision levels ranged from -240 U/L to 113 U/L.For A to D,the Lp-PLA2 activity results of 131(93.6%), 140(100%), 82(58.6%), and 128(91.4%)cases were analysed within the manufacturer′s claimed reference intervals.Conclusion The precision and linearity of the four Lp-PLA2 activity detection reagents used in automatic biochemical analyzer are good, but the anti-interference ability needs to be improved.
