Objective: To study the correlation of blood stasis syndrome or its accompanied syndromes with Gensini score in patients with coronary heart disease (CHD) in stable condition. Methods: The syndrome types of traditional Chinese medicine (TCM) and blood stasis score in 131 CHD patients confirmed by coronary angiography were recorded. Gensini score was calculated according to the coronary pathological characteristics showed by angiography. The correlations of blood stasis syndrome and its accompanied syndromes with coronary lesion and Gensini score were analyzed. Results: Among the TCM syndrome types, blood stasis, turbid phlegm and qi deficiency were the most common syndromes, revealed in 85 patients (64.9%), 83 patients (63.4%) and 85 patients (64.9%), respectively. The coronary lesion length and Gensini score in the patients with blood stasis syndrome were much higher than those in the patients with non-blood stasis syndrome (P<0.05 or P<0.01). In the subtypes of blood stasis, the coronary lesion length and Gensini score in the patients with blood stasis accompanied by turbid phlegm syndrome were higher than those in the patients with non-blood stasis syndrome (P<0.05). And in the patients whose blood stasis syndrome score was more than 9 points, the coronary lesion length was higher than that in the patients whose blood stasis syndrome score was less than 9 points (P<0.05). Besides, with bivariate analysis, the blood stasis syndrome score showed no correlation with Gensini score (Pearson correlation coefficient was 0.104, P=0.241). Conclusion: Blood stasis syndrome is the most common TCM syndrome in CHD patients in stable condition. The blood stasis syndrome score is proportional to coronary lesion length, and reflects the severity of coronary lesion.

Objective To study X-ray, CT and MRI features of the spinal giant cell tumors (GCT)and to assess the clinical applied value.Methods Thirty cases of GCT of spine (13 males and 17 females with ages ranging from 17 to 69 years) were reviewed. Allcases underwent radiography,CT was done in 22 patients and MRI was performed in 16 cases.Results One lesion localized in cervical spine,10 in thoracic, 6 in lumbar and another 13 lesions in the sacrum.Osteolytic destruction and vertebral compression were seen on X-ray film. The main CT signs were expanding bone destruction and soft tissue mass. MRI showed low to intermediate signal intensity on T_1WI while high signal on T_2WI.Conclusion X-ray, CT and MRI are of significant value in diagnosis of the spinal GCT, and play an important role in surgical planning.

Objective To explore the four criteria,including bedside index for severity in acute pancreatitis(BISAP),Ranson score,modified CT severity index(MCTSI) and acute physiology and chronic health evaluation scoring system Ⅱ (APACHE Ⅱ) in assessment of severity and prognosis of hyperlipidemic acute pancreatitis.Methods A total of 326 patients with hyperlipidemic acute pancreatitis were studied retrospectively from August 2006 to July 2015.The discrepancy of the four criteria in assessment of severity and prognosis of hyperlipidemic acute pancreatitis was compared with chi-square test and receiver operating characteristic curve.Results The incidences of moderately severe acute pancreatitis and severe acute pancreatitis,local complications and mortality of patients with BISAP score ≥3,Ranson score ≥3,APACHE Ⅱ score≥8 and MCTSI score≥4 were significantly higher than BISAP score ＜ 3,Ranson score ＜ 3,APACHE Ⅱ score ＜ 8 and MCTSI ＜ 4 respectively (all P ＜ 0.05).As far as severity was concerned,the sensitivity and AUC of APACHE Ⅱ were 57％ and 0.814,which were higher than the other systems.The second most sensitive criterion was BISAP.In assessment of local complications,the sensitivity and AUC of MCTSI were 68％ and 0.791,which were higher than the other three.The most sensitive criterion to predict mortality was BISAP with sensitivity 89％ and AUC 0.867,which was followed by APACHE Ⅱ.Conclusions All four criteria can be used to determine the severity,local complications and mortality.Generally,BISAP is simple and easy to practice,and better than the other three.

Objective To study the influence of carboxymethyl-chitosan (CM-chitosan) on phenotype and proliferation of chondrocytes stimulated by recombinant human interleukin-1? (rhIL-1?), and explore its mechanism. Methods Chondrocytes were isolated and cultured. 10 ng/ml IL-1? with or without CM-chitosan of varied concentrations were added into the culture medium. After 24 h, changes of proliferative ability of chondrocytes were tested by MTT and flow cytometry. Proteoglycan synthesis was measured by incorporation of Na235SO4 into chondrocytes, nitric oxide (NO) production was detected by Greiss reaction, mRNA expression of typeⅠ、Ⅱcollagens, Aggrecan and inducible NO synthase (iNOS) were examined by semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR). Results CM-chitosan could significantly antagonize IL-1?-induced inhibitory effect on proliferation of chondrocytes, restore proteoglycan synthesis of chondrocytes, decrease NO production of IL-1?-induced chondrocytes, increase the mRNA expression of typeⅡcollagen and Aggrecan, but decrease the expression of typeⅠcollagen and iNOS. The effects of CM-chitosan were in a dose-dependent manner. Conclusion CM-chitosan can maintain the proliferation and phenotype of IL-1?-induced chondrocytes.

Objective: To prepare ibuprofen sustained-release dropping pills, to evaluate the accumulative release percentage in vitro and to study the drug state in the base.Methods: With the drug content, mass ratio of water-soluble base to insoluble base and mass ratio of stearic acid to glyceryl monostearate as the investigation factors, and the comprehensive score of 2-hour and 10-hour cumulative dissolution rate as the evaluation index, a Box-Behnken response-surface method was used to screen the optimal formula of ibuprofen sustained-release dropping pills.The drug state in the matrix was examined by differential scanning calorimetry (DSC).Results: The optimal formula of ibuprofen sustained-release dropping pills was as follows: the drug content of 10%, water-soluble and insoluble matrix ratio of 4∶1, and stearic acid and glyceryl monostearate ratio of 3∶1.The maximum cumulative dissolution rate of ibuprofen sustained-release dropping pills was 78.85%.The DSC analysis showed that the drug crystallization peak disappeared in the sustained-release dropping pills, and formed a solid dispersion.Conclusion: The preparation has good sustained-release effect, and the preparation process is simple.

Objective To explore risk factors of cardiac surgery in neonates with low body weight.Methods Retrospective analysis was made in neonates weighing less than 3 kg at surgery(n =192;group 1) and 3 to 6 kg(n =517;group 2),who had undergone open cardiac repairs from January 2006 to December 2015 at our institution.Patients were grouped according to the primary procedure performed and analyzed according to their weight at the time of surgical intervention.Patients were also analyzed according to preoperative risk scores.Univariate versus multivariate risk analysis was performed.Results Hospital early mortality in group 1 was 25.0％ (n =48) versus 14.5 ％ (n =75) in group 2 (P =0.001).Compared with group 2,neonates in group 1 had a significantly higher mortality for simple arterial switch procedure.Lower body weight remained strongly associated with mortality risk after stratifying the population by preoperative risk scores category levels 2.Within group 1,age,weight at surgery,preoperative risk score and type of procedure were not associated with significant differences in early mortality.Cardio-pulmonary bypass time,aortic cross-clamp time and the presence of a surgical complication were independent risk factors for early mortality in group 1.Conclusion Among neonates weighing less than 3.0kg who underwent open cardiac surgery,perioperative hemodynamic status,reflected by bypass time,cross-clamp time,and surgical complications,strongly influenced early mortality.In contrast,low body weight itself was not associated with early mortality.

Objective To study the telomerase activity,the keratinocyte apoptosis in condyloma ac-cuminatum(CA)and the correlation between them.Methods CA specimens from30patients were stud-ied,and compared with normal tissue and tumor cell lines.Telomerase activity was detected with telomeric repeat amplification polymerase chain reaction(TRAP)-ELISA.Terminal deoxynucleotidyl transferase(TdT)-mediated biotin dUTP nick end-labeling(TUNEL)was used to evaluate apoptotic cells.Results Increased telomerase activity was detected in27(90%)patients with CA,with A 450 ranging between0.50and2.76(mean1.3022).Apoptotic keratinocytes were found in24out of30CA cases(80%).A statistically signifi-cant inverse correlation was found between telomerase activity and apoptotic index(r =-0.52,P=0.004).Conclusion Keratinocyte telomerase is activated in condyloma acuminata,which is correlated with the downregulation of apoptosis,thus they might be involved in the pathogenesis of CA.

Objective To summarize the effect of en bloc kidney transplantation (EBKT) from cardiac deceased infant donors into adult recipients and to share a new simplified EBKT technique.Methods Fourteen dual kidneys from infant donors (9 males,and 5 females) were transplanted into adult recipients (3 males,and 11 females).The donor ages ranged from 17 days to 8 months,and the recipient ages ranged from 19 years to 61 years.The recipients were categorized into 2 groups in terms of the microvascular surgical techniques.Case 1 to case 9 was given traditional techniques and case 10 to case 14 simplified techniques.In detail,the dual kidneys were recovered en bloc with the aorta and inferior vena cava.After splitting the rear wall of the donor aorta and inferior vena cava,suitable size of patches were made by cutting along the vascular openings of renal arteries and renal veins.We anastomosed the aorta patch to the external iliac artery in an end-to-side fashion.The donor inferior vena cava patch was anastomosed to the external iliac vein in an end-to-side fashion.The distal ends of ureters were implanted into the bladder separately.Results In traditional group,two cases underwent peri-operative graft loss because of renal artery thrombosis,and one patient died of pneumonia 16 days post-operation.During the follow-up period,graft loss was seen in 2 patients caused by irreversible drug-induced nephrotoxicity and donor-derived malignant tumor respectively.The mean serum creatinine level was 81.7 ± 27.4 μmol/L and eGFR level was 82.5 ± 22.2 mL/min/1.73 m2 in the other EBKT recipients at 24th week post-operation.In simplified group,no vascular complications post-operation occurred.Conclusion En bloc infant kidneys could be transplanted into adult recipients successfully with excellent graft function and survival outcome while censored perioperative patient death and surgical failure.Instead of traditional EBKT technique,simplified EBKT technique could decrease the incidence of surgical vascular complications and should be applied to more recipients.

Objective:To evaluate the immunogenicity of recombinant factor H binding protein(fHBP) by detecting serum antibody titer and serum bactericidal antibody test (SBA).Methods:fHBP sequence was selected and synthesized, connected to plasmid pET43.1a, transformed to Escherichia coli BL21(DE3), and expressed two recombinant fHBP proteins, included two subfamilies, fHBPA and fHBPB. After purification, the recombinant fHBP proteins were immunized to rabbits and mice. The immune antiserum titer and the bactericidal titer to epidemic strains of meningococcal bacteria group B were measured by ELISA and SBA respectively. Results:The antiserum titer of fHBP immunized rabbits was greater than 2.0×10 6, and that of immunized mice was not less than 1.0×10 6. fHBP immunized rabbit serum had bactericidal titer more than 1∶128 to 41 strains A subfamily and 20 strains B subfamily in the SBA against 69 endemic strains, and there was no cross-protection between the subfamily bacteria. The bactericidal titers of mouse serum immunized fHBPA to strains A subfamily such as Nm210902 Nm211009、Nm450522 were 1∶1 024, 1∶608、1∶861, to Nm510703、Nm311304、Nm431002 were 1∶234、1∶861、1∶430 respectively, and mouse serum immunized fHBP B to strains B subfamily Nm311302、Nm311304、Nm431002 were 1∶876、1∶274、1∶1858, all of three strains were positive in bactericidal titers. Conclusions:the titer of fHBP antiserum was higher than 1.0×10 6, the bactericidal titer was no less than 1∶128 to 61 epidemic strains, and it has a 94.2% protective effect on 69 meningococcal epidemic strains group B.
