ABSTRACT
BACKGROUND: Recent studies have shown that Taohong Siwu Decoction can alleviate the damage of vascular endothelial cells and maintain their normal secretory function, and endothelial progenitor cells can promote the repair of endothelial injury. Therefore, it is assumed that Taohong Siwu Decoction may protect endothelial function by improving the functional activity and increasing the number of endothelial progenitor cells. OBJECTIVE: To investigate whether Taohong Siwu Decoction can augment the number and functional activity of peripheral blood endothelial progenitor cells. METHODS: Endothelial progenitor cells were isolated from the peripheral blood of healthy subjects, and divided into control, low-, moderateand high-concentration Taohong Siwu Decoction groups. Cells were then cultured to observe the dose-effect relationship within 24 hours. Meanwhile, the high-concentration Taohong Siwu Decoction group was cultured for respective time points (6, 12, 24 and 48 hours) for observing the time-effect relationship. The number of endothelial progenitor cells was counted under inverted phase contrast microscope. Proliferation, adhesion and migration of endothelial progenitor cells were detected by MTT chromatometry, adhesion activity assay and modified Boyden chamber assay, respectively. RESULTS AND CONCLUSION: (1) The proliferation, adhesion and migration abilities of endothelial progenitor cells in the Taohong Siwu Decoction groups were significantly higher than those in the control group and showed a certain dose-effect relationship. (2) The proliferation, adhesion and migration abilities of endothelial progenitor cells in the Taohong Siwu Decoction groups were enhanced in a time-dependent manner, especially at 24 hours after intervention (P < 0.01). To conclude, the Taohong Siwu Decoction can increase the number of endothelial progenitor cells and promote cell functions. High-concentration Taohong Siwu Decoction exhibits the best interventional effect at 24 hours after intervention.

ABSTRACT
At present,surgery is still the best way to treat resectable non-small cell lung cancer (NSCLC).For clinicians,TNM stage is the main indicator to judge surgical outcomes,but the prognosis of patients with same stages still has big differences.The related studies have shown that the prognostic factors for patients with NSCLC after surgical treatment include poor lung function,the suffering from cardiovascular diseases,male,advanced age,comorbidities,advanced TNM stage,non-adenocarcinoma and pneumonectomy.Many results of prognostic factors research are controversial;meanwhile,the effects of molecular biological factors,neoadjuvant therapy and adjuvant therapy on prognosis still need further study.
ABSTRACT
Objective To investigate the application of bundles of intervention in the treatment of postoperative delirium in esophageal cancer.Methods Thirty-six cases of delirium associated with esophageal cancer(study group)after the application of bundles of intervention in the Affiliated Huaian No.1 People's Hospital of Nanjing Medical University from November 2015 to August 2016 were analyzed,and 41 cases of postoperative delirium(control group)from January 2015 to October 2015 were treated by routine treatment.Results The mean duration of postoperative delirium was(3.6±0.8)d in the study group and(4.7± 1.2)d in the control group,and the difference was statistically significant(t =4.783,P<0.01).The incidence rates of other complications in the study group and control group were 19.4％(7/36)and 34.1％(14/41),respectively,and there was no significant difference(χ2=2.089,P=0.148).The incidence rates of accidental events in the study group and control group were 13.9％(5/36)and 31.7％(13/41),respectively,and the difference was statistically significant(χ2= 4232,P= 0.040).There was no significant difference in the postoperative exhaust time and removal of chest tube drainage time between the two groups(both P＞ 0.05),but there was a significant difference in postoperative hospital stay and hospital costs between the two groups(t values were 4.726 and 2.065,both P<0.05).Conclusions In the treatment of postoperative delirium in esophageal cancer,applying the bundles of intervention concept is feasible and effective.It can significantly reduce postoperative delirium duration and accelerate the rehabilitation of patients.
ABSTRACT
Objective To investigate the clinical efficacy of basiliximab-induced glucose-free corticosteroid immunosuppressive regimen after liver transplantation.Methods The retrospective cohort study was conducted.The clinicopathological data of 227 patients with liver transplantation who were admitted to Bayi Hospital affiliated to Nanjing University of Traditional Chinese Medicine from January 2010 to October 2016 were collected.Of the 227 patients,125 who postoperatively received a glucose-free corticosteroid immunosuppressive regimen using a monoclonal antibody + tacrolimus + mycophenolate mofetil tablets were allocated into the hormone-free group,and 102 who were postoperatively treated with the immunosuppressive regimen using glucocorticoid steroid + tacrolimus + mycophenolate mofetil tablets were allocated into the hormone group.Observation indicators:(1) comparison of follow-up and survival;(2) comparison of postoperative infection,rejection and biliary stenosis between groups.Follow-up using outpatient examination and telephone interview was performed to detect postoperative survival,infection,rejection and biliary stenosis up to June 2017.The measurement data with normal distribution were represented as (x) ± s,and comparison between groups was done by the t test.Measurement data with skewed distribution were described as M (P25,P75) and M (range),and comparison between groups was analyzed using the rank sum test.The count data were compared by the chi-square test.Kaplan-meier method was used to draw survival curve and calculated survival rate.Log-rank test was used for survival analysis.Results (1) Comparison of follow-up and survival:patients between groups were followed up for 9-89 months,with a median time of 45 months.The 1-and 3-year overall survival rates were respectively 93.25％,85.24％ in the hormone-free group and 89.89 ％,74.22％ in the hormone group,with a statistically significant difference (x2 =8.450,P＜0.05).(2) Comparison of postoperative infection,rejection and biliary stenosis between groups:① The total cases with postoperative infections,cases with infection of Klebsiella pneumoniae,Staphylococcus aureus,Candida,Acinetobacter baumannii and Stenotrophomonas maltophilia were 25,18,3,2,2,0 in the hormone-free group and 40,26,6,3,3,2 in the hormone group,respectively,showing a statistically significant difference between groups (x2 =10.149,P＜0.05).The patients between groups with postoperative infection were treated with active anti-infective symptomatic treatment.Three patients in the hormone group died of severe pulmonary infection,and the remaining patients in both groups were improved.② The cases with postoperative rejection in the hormone-free group and hormone group were 6 and 5,respectively,with no statistically significant difference (x2 =0.950,P＞ 0.05).The rejection of both groups occurred within 1 week postoperatively.Two patients in the hormone group were treated with glucocorticoid hormonal shock.The other patients in the 2 groups were improved by adjusting the amount of tacrolimus and mycophenolate mofetil tablets.③ The cases with postoperative biliary stenosis in the hormone-free group and the hormone group were 32 and 8 respectively,with a statistically significant difference (x2 =12.200,P＜0.05).In the hormone group,biliary stenosis occurred after stopping glucocorticoids.The patients with biliary stenosis were improved after biliary stent implantation by endoscopic retrograde cholangio pancreatography (ERCP).Conclusion The basiliximab-induced glucose-free corticosteroid immunosuppressive regimen after liver transplantation is safe and feasible,and it can significantly reduce the incidence of postoperative infection and improve long-term overall survival compared with the conventional glucocorticoid immunosuppressive regimen,but increased postoperative biliary stenesis.
ABSTRACT
Objective To approach the effect of telbivudine for preventing recurrence of virus and improving renal function in patients with hepatitis B cirrhosis after liver transplantation with renal insufficiency,and observe the mid-and long-term efficacy.Methods We prospectively researched 17 cases of hepatitis B cirrhosis after liver transplantation with renal insufficiency.Maintenance irnmunosuppression protocol at our centre mainly included calcineurin inhibitor (tacrolimus for 12 cases,and sirolimus for 5 cases).These recipients (n =17) remained under the entecavir (n =10),tenofovir (n =4),lamivudine + adefovir (n =3) for at least 6 months before transformation to telbivudine.We detected HBV-DNA level in serum and ensured no rejection during study,necessarily punctured the graft liver for biopsy to determine if there was rejection.The basal values of blood serum creatinine (Scr) and estimated glomerular filtration rate (eGFR,CKD-EPI formula) were recorded.The Scr and eGFR at 6th month before research and basal values and at 6th and 12th month after telbivudine administration were detected,at the same time the general state and adverse reactions were evaluated.Results During the average follow-up period of 20.2 months,1 patients died.The Ser levels detected in the rest 16 patients were 105.74± 18.24,112.26± 18.67,96.48±22.0 and 89.17± 19.56μμmol/L respectively at 6th month before,basal time and 6th,12th month after telbivudine administration.The eGFR values were 72.56 ± 14.39,66.23 ± 16.61,79.77 ± 20.15 and 83.93 ± 23.67 mL/(minute,m2) at different time points respectively.As compared with the basal value,the Scr and eGFR levels were improved obviously (P＜0.05) at 6th and 12th month after telbivudine administration.The proportion of patients with eGFR ＜60 mL/(min·m2) in 16 cases was 25％,37.5％,12.5％ and 6.3％ respectively at 6th month before,basal time and 6th,12th month after telbivudine administration.The serum creatine phosphokinase level was increased (1 023 IU/L) in 1 patient (6.3％),and decreased after transformation of telbivudine to tenofovir at 3rd month after end of research.No rejection and HBV occurred.Conclusion The telbivudine improves renal function in patients with hepatitis B cirrhosis after liver transplantation with renal insufficiency.Meanwhile,telbivudine prevents hepatitis virus B recurrence.However,large samples of long-term clinical data are needed to further confirm.
ABSTRACT
Objective To investigate global cerebral blood flow perfusion in fetuses with congenital heart disease (CHD)by three-dimensional power Doppler ultrasound (3D PD).Methods The vascular index (VI),flow index (FI)and vascular/flow index (VFI)in the global cerebral were prospectively compared in 1 12 fetuses with CHD and 1 12 normal fetuses using 3D PD.Correlations between the 3D PD indices and neurodevelopment scores were assessed.Results Compared with the controls,the VI,FI and VFI of the global brain were significantly increased in fetuses with hypoplastic left heart syndrome (HLHS) and left sided obstructive lesions (LSOLs)(P <0.001).The mean psychomotor development index (PDI) and mental development index (MDI)scores were significantly lower than normal (P < 0.001 ).FI was positively correlated with PDI (r =0.342,P =0.029)and MDI (r =0.339,P =0.030).Conclusions Global cerebral blood flow perfusion was significantly increased in most fetuses with CHD and had association with neurodevelopment scores.3D PD ultrasound might help to identify cases of brain vasodilatation earlier and inform parental counseling.
ABSTRACT
Objective To explore the serum levels of brain-derived neurotrophic factor in patients with depression and their correlation with age,gender,age of onset,illness course,depressive severity.Methods Serum BDNF levels in 91 depressive patients and 36 healthy controls were assayed by the ELISA method .The clinical char-acteristics were assessed by the Hamilton Rating Scale for Depression ( HAMD) .Results The serum BDNF levels in depressive patients were (24.38 ±6.27)μg/L,which was significantly lower than (31.44 ±10.72)μg/L in controls (t=3.708,P 0.05).Conclusion Serum BDNF levels in depressive patients was decreased and low levels of BDNF in serum may be a state characteristic for depression .
ABSTRACT
Objective To detect the expressions of human telomerase tranacriptase (hTERT) and MMP-7 mRNA in the peripheral blood of patients with cardia cancer.Methods Total RNA was extracted with TRIzol and was transcribed reversely into cDNA.RT-PCR was used to detect mRNA expression of MMP-7 and hTERT in the peripheral blood of 157 patients with cardia cancer.81 patients without metastasis were followed up for 12 months.Results Of 157 patients,73 cases (46.0 ％) and 61 cases (38.8 ％) had the positive expressions of hTERT,MMP-7,respectively.There were significant correlations between the blood micro-metastases MMP-7 and hTERT expressions and TNM staging (x2 =10.624,14.530),tumor metastasis (x2 =7.294,12.824),and differentiation degree (x2 =12.003,6.482),but no significant correlations were seen in sex (x2 =2.597,0.199) and age (x2 =4.314,0.073).There was statistically significant in the occurrence rate of tumor metastasis between 6-month and 12-month follow-up.The occurrence rate of metastasis in patients with micro-metastases was 6.12-fold compared with patients without micro-metastases after 12-month follow-up.Conclusion Detection of MMP-7 and hTERT expressions can be used as reliable markers to predict peripheral blood micro-metastasis in patients with cardia carcinoma.

ABSTRACT
Objective To investigate the effect of Aidi injection combined with chemotherapy on CD+4CDhi25CDlow127regulatory T (Treg) cells in peripheral blood of advanced non-small-cell lung cancer (NSCLC).Methods Sixty patients with advanced NSCLC were randomly divided into the study group (treated with Aidi injection combined with chemotherapy) and the control group (treated with chemotherapy).The levels of CD+4CDhi25CDlow127Treg cells were detected by flow cytometry (FCM), and TGF-β1 and IL-10 levels were determined by enzyme linked immunosorbent assay (ELISA) before and after chemotherapy. A group consisted of 20 healthy persons was set up meanwhile.Results There was a significantly higher percentage of CD+4CDhi25CDlow127Treg cells in patients with NSCLC (5.77±1.50) % than that(3.84±0.96) % of healthy volunteers (P=0.000).The IL-10 and TGF-β1 levels[(24.09±6.74), (197.76±43.76) ng/ml]in the serum of patients with NSCLC were also significantly higher than that[(19.39±5.73), (141.13±32.17) ng/ml]of healthy volunteers (P =0.006,P =0.002). In control group, levels of CD+4CDhi25CDlow127 Treg cells were obviously lower than that before chemotherapy (P =0.048).Levels of TGF-β1 and IL-10[(22.25±6.79), (184.85±49.11) ng/ml]were slightly decreased, which showed no significant difference contrast to pretherapy[(24.37±8.10), (197.16±44.57) ng/ml](P =0.276, P =0.314).In study group, levels of CD+4CDhi25CDlow127Treg cells and TGF-β1, IL-10[(4.36±1.19) %,(20.16±4.73), (165.42±39.57) ng/ml]were obviously lower than that before chemotherapy[(5.78±1.50) %,(23.81±5.15), (198.35±43.68) ng/ml](P=0.000, P=0.003, P =0.006).Conclusion The CD+4CDhi25CDlow127 Treg cells in the peripheral blood of advanced NSCLC patients is significantly increased. Aidi injection combined with chemotherapy can obviously reduce the level of CD+4CDhi25CDlow127 Treg cells in patients with advanced NSCLC, and the combined therapy could improve the immune function of patients.
ABSTRACT
Objective To observe the curative effect of sirolimus conversion for liver transplantation patients with chronic renal injury.Methods In 23 recipients of liver transplantation using CNI (19 cases using tacrolimus,and 4 cases using cyclosporine A) with chronic renal injury,the immunosuppressant was converted to sirolimus (SRL).The initial dose of SRL was 4 mg per day and 2 mg at the next day.The blood SRL concentration was determined by using high pressure liquid chromatography.When the valley value of SRL concentration reached a range between 5 to 8μg/L,CNI was withdrawn and MMF (1 g/day) was given simultaneously.The basal values of serum creatinine (Scr),creatinie clearance rate (Ccr) and glomerular filtration rate (GFR) were recorded in the recipients before study,and at 1st,3rd,6th,12th,and 24th month after using SRL,blood SRL concentration,Scr,Ccr and GFR,as well as body weight,blood pressure,blood cells count,liver function (serum bilirubin,albumin and prothrombin time),liver biochemistry (AST,ALT,γ-GT and AKP),blood fat (cholesterol and triglyceride) and urine protein were monitored.At the 12th month after using SRL,the graft liver was biopsied to diagnosis rejection.Results During an average followup period of 29.4 months,there were two deaths.In the remaining 21 cases,the Scr values were (147.40 ± 23.36),(152.60 ± 20.08),(150.20 ± 22.64),( 137.60 ± 18.09) and (138.30 ± 17.04)μmol/L,respectively at 1st,3rd,6th,12th,24th month after using SRL.As compared with basal Scr values [(158.91 ± 29.13) μmol/L],there were statistically significant differences at 1at,12th,24th month (P＜0.05).The Ccr values were (0,97 ± 0.18),(0.99 ± 0.1 4),( 1.00 ± 0.17),(1.07 ±0.29) and (1.14±0.12) ml/s,respectively at 1st,3rd,6th,12th,24th month after using SRL.As compared with basal Ccr value [(0.91 ± 0.14) ml/s],there were statistically significant differences at 1st,12th,24th month (P＜0.05).The GFR values were (0.80 ± 0.15),(0.78 ± 0.11),(0.75 ±0.12),(0.84 ± 0.10) and (0.94 ± 0.13) ml/s,at 1st,3rd,6th,12th,24th month after using SRL.As compared with basal GFR value [(0.71 ± 0.11) ml/s],there were statistically significant differences at 1st,12th,24th month (P＜0.05).The proportion of patients with Scr≤123 μmol/L in 21 cases was 38.1％,33.3 ％,28.6 ％,47.6 ％ and 52.4 ％,respectively at 1 st,12th,24th month (P＜0.05).No rejection cases were observed.Conclusion The immunosuppressant conversion to SRL improves renal function of liver transplantation patients with chronic renal injury,and the conversion cure can not cause rejection.
ABSTRACT
Objective To approach the reason and treatment of arrhythmia after total pneumonectomy. Methods 94 arrhythmic cases after total pneumonectomy surgery were reviewed, the arrhythmia's clinical types, developing reasons and treatment process were summarized. Results There are 34 arrhythmic cases (36.2%) in all the 94 patients, most of them are sinus tachycardia. The incidences of arrhythmic are about 22.5 % and 78.3 % for normal and abnormal ECG patients before operation. The incidences of arrhythmic are also about 24.2% and 28.1% for using PCEA or not using any pain killers after surgery. Conclusion Arrhythmia after total pneumonectomy was influenced by patients' age, previous medical history, suffered hypoxemia during operation and high cardiac irritability. Using interventional treatment for patients with cardiovascular disease before operation, give enough oxygen, keep respiratory tract ease and smooth and using analgesia can significantly decease the arrhythmic incidence after total pneumonectomy.

Results There was a significantly higher percentage of CD4+ CD25hi CD127low Treg cells in patients with cardiac cancer (5.73±1.56)% than that (4.45±1.06)% of healthy volunteers (P<0.01).The IL-10 and TGF-β1 levels in the serum of patients with cardiac cancer were also significantly higher than that of healthy volunteers (P<0.05).There was a positive correlation between levels of IL-10.TGF-β1 and the levels of CD4+ CD25hi CD127low Treg cells.The number of CD4+ CD25hi CD127low regulatory T cells in the peripheral blood of cardiac cancer patients were significantly correlated with clinical stages and metastasis lymph node.Conclusion The CD4+ CD25hi CD127low Treg cells in the peripheral blood of cardiac cancer patients is significantly increased in comparison with that in healthy volunteers,and was also correlated with different stages.The abnormal levels of CD4+ CD25hi CD127low Treg cells may be related to tumor progression in patients with cardiac cancer.
ABSTRACT
Objective To detect the expression of CD133 in hepatic cell lines SMMC7721 and bcl-7402, and to investigate the possibility of CD133 as the surface marker of liver cancer stem cells. Methods The cell cycle and expression of CD133 in hepatic cell lines SMMC7721 and bcl-7402 were detected by flow eytometry. Magnetic cell sorting was used to isolate CD133-positive and CD133-negative cells. The differences in morphology, proliferation and differentiation between CD133-positive and CD133-negative cells were observed and analyzed by one-way ANOVA and u test. Results The percentages of CD133-positive cells in SMMC7721 and bcl-7402 cell lines were 0.7% -1.0% and 1.7% -8.9%, respectively. The percentages of CD133-positive cells in G0>/G1> phase in the 2 cell lines were 85.3% and 89.4%, which were significantly higher than CD133-negative cells and unsorted cells (F = 14.49, 38.84, P <0.05). The in vitro proliferation capability of CD133-positive cells was greater than that of CD133-negative cells and unsorted cells, especially during day 1-3 and day 5-7 (F =49.32,784.04, 89.91, 152.83, P < 0. 05). During the cultivation, the proportion of the CD133-positive cells decreased as time passed by, and the proportion of CD133-positive cells was nearly the same as unsorted cells on day 15 (u =O. 271, P <0.05). Conclusions CD133-positive ceils have strong capability of proliferation and differentiation in SMMC7721 and bcl-7402 cell lines in vitro. CD133 is one of the surface markers of liver cancer stem cells.

In this paper is recommended a highly sensitive and reagent-safe method to determine plasma heamoglobin (FHb) in viscacha hemolytic test. The 2,4-dichlorophenol method (2,4-DCP) of Trinder reaction has been improved. The performance of 2,4-DCP is verified. The sensitivity of 2,4-DCP is 2.39 times that of phenol method. It is well used with run precision and day-to-day precision. The reaction color is stable. The reference value FHb is 1-36.7 mg/L. Sodium citric is an excellent anticoagulant liquid to keep erythrocyte. The 2,4-DCP method is neither carcinogenic nor poisonous;it is suitable for viscacha hemolytic test in clinical and biomedical engineering.
