Objective To detect the expression of apoptotic inhibitor protein Livin in different esophageal epithelial lesions and to analyze the relation between the expression of Livin with pathologic characteristics. Methods The expressions of Livin mRNA and Livin protein were detected by real- time fluorescence quantitative PCR and western blot in 40 patients with different esophageal epithelial lesions including normal, atypical hyperplasia, carcino-ma in stiu and invasive carcinoma. Results The expressions of Livin mRNA were progressively increased from nor-mal to invasive carcinoma( 1.00 ± 0. 00,2.26 ± 0.79,7.24 ± 1.06,12.21 ± 2.47 ). There was statistical signifi-cance in Livin mRNA expression among carcinoma in stiu and invasive carcinoma and normal tissues ( P < 0.05 ). Conclusion The expression of Livin is significantly related to the progression of esophageal cancer,which may be a new target for diagnosis and gene treatment of esophageal carcinoma.

OBJECTIVE: To explore the effect of different pressure on microcirculation of scar proliferation. METHODS: A total of 60 patients with scar proliferation after burning were collected, including 49 males and 11 females, with averagely aged 37 years. The patients were divided into low pressure (0.67-1.33 kPa), normal pressure (1.33-3.33 kPa) and high pressure (3.33-6.67 kPa) groups by envelope method. Pressure tension bandage was used at 1 week after wound healing and gradually increased, reached expected pressure at days 5-7 and sustained for 6 months. Then the changes of blood perfusion at the scar tissue were measured by laser Doppler perfusion imaging (LDPI). RESULTS: According to the intended processing analysis, all the 60 patients enter the result analysis. There were no significant differences of the scar tissue perfusion of the 3 groups before the therapy. After the therapy, the perfusion was decreased in the low pressure group, but there are no statistical changes compared to before the therapy (P > 0.05), while the perfusion was decreased in the normal pressure and high pressure groups (P < 0.05), which was lower in the high pressure group than the normal pressure group (P < 0.05). When the pressure increased to 3.33-6.67 kPa, the patients feel much more uncomfortable and the swelled signs appear, and 2 patients quit the experiment. CONCLUSIONS: The scar tissue perfusion is decreased obviously when adding the pressure to 3.33 kPa by using tension bandage. Using this method, the pressure should gradually increase to the maximum if patients can bear.

Objective To know the establishment of the flap pedicle blood supply and the right moment of the cutting off of pedicle by means of laser Doppler blood perfusion imaging instrument on the random flap blood flow changes.Methods 20 adult healthy rabbits were divided in to four groups and each 5 have unilateral flaps.1,3,5,7,9,12,14,18 days after operation,the pedicle blood perfusion values (PU) measurement of the distal pedicle on the flap and midpoint of both ends of the pedicle were performed,and PU values were analyzed.Results Pedicle of the PU values at the different time points changed little (P＞0.05).The PU value in the distal flap reached the minimum 1 day after operation and then increased gradually [3 d (1.24±0.07),5 d (1.57±0.15),7 d (1.79±0.08),9 d(1.89±0.13),12 d(2.01±0.16),14 d(2.18±0.09) and 18 d(2.40±0.18),P＜0.05].When distal PU values/pedicle PU value≥1.2,the flap survival rate reached 99%.Conclusions The establishment of random skin flap blood circulation,as well as the ratio of PU values of distal to the pedicle flap pedicle can be used as the timing of an important indicators.

BACKGROUND: Random flap as a primary means of wound healing, is widely used at present, its blood circulation to establish the situation is also researched a lot, but not yet the system of random skin flap perfusion were observed and measured. In addition, the timing of pedicle division of a pedicle flap random is also a hot topic, but not yet a mature clinical testing method has been discovered to determine the best timing.OBJECTIVE: By means of laser Doppler blood perfusion imaging, this study was designed to dynamically observe random flap microcirculation, to understand the changes on random flap blood flow, and to determine the best timing of pedicle division. METHODS: A total of 18 cases were divided into traditional pedicle division group and early pedicle division group. Pedicle flap blood perfusion values were statistically measured immediately after surgery, at 3, 7,11,15, and 19 days after surgery, before division, immediately after division, and at 24 hours after pedicle division, 8-9 phases in total.RESULTS AND CONCLUSION: Distal blood perfusion value was increased with the time prolongation in both groups; while, the blood perfusion in various time phases was significantly different from that after surgery (P < 0.05); but, the blood perfusion was decreased immediately after surgery, which was still significantly compared with traditional pedicle division group (P< 0.05). There was no significant different in blood perfusion between early pedicle division and immediate after surgery of pedicle division (P > 0.05), but there was significant difference between 24 hours after pedicle division and immediate after surgery of pedicle division (P< 0.05). Blood perfusion values were less changed in both groups (P> 0.05). The ratio of both groups peaked before pedicle division and then gradually decreased after pedicle division. The best timing of pedicle division was the ratio of 1.2.

BACKGROUND: Pentoxifylline (PTX), as an effective drug to improve blood rheology, has been used as a vasodilator for the treatment of vascular diseases and peripheral vascular disease science 1960s. But the role of PTX on skin blood flow to improve flap survival remains still unclear. OBJECTIVE: Through the clinical application of PTX therapy, the dynamic observation of random flap to understand that the PTX can promote flap survival and improve blood circulation of flap. METHODS: A total of 39 patients (27 males and 12 females aging 7-54 years) with skin tissue defect undergoing random flap repairing were selected from Department of Burn and Plastic Surgery, First Hospital of Hebei Medical University. The 39 cases were randomly divided into control group and drug group. Patients in the drug group were given intravenous injection of 250 mL PTX at day 2 after random flap operation, once a day, until 14 days after flap repairing surgery. On the first day after flap pedicle surgery, 250 mL PTX sodium chloride injection was intravenously given, once a day, until 7 days after flap pedicle surgery. The control group was not given PTX treatment. The value of blood perfusion (PU) was measured using laser-Doppler blood reperfusion image after flap transplantation, before and after pedicle division. RESULTS AND CONCLUSION: All 39 patients were completely cured and discharged, with no interruption experiments. Before pedicle division, PU value at distal flap in both drug and control groups were increased obviously, and the PU value in the drug group was significantly higher than control group (P < 0.05); after pedicle division, the PU value in the two groups were decreased, and there was no significant difference between the two groups (P > 0.05). Prior to pedicle division, the PU value of pedicle was gradually decreased and then increased in the drug group, and that in the control group was gradually increased. On the seventh day, the PU value of pedicle was stable in the drug group, and there was no significant difference between the two groups (P> 0.05); after pedicle division immediately, the PU values of pedicle were decreased in the two groups, and then the increase in the drug group was remarkable compared to control group (P < 0.05). Two sets of random flaps all survived, and skin defects were successfully repaired after pedicle division. PTX can markedly increase blood perfusion after random flap transplantation, promote flap survival and pedicle division in an early stage, and effectively shorten the healing time.

Objective To investigate clinical effects of Deanxit in non-erosive gastroesophageal re-flux disease ( NERD) with anxiety and depression.Methods A total of 76 patients diagnosed NERD with anxiety and depression by endoscopy and hospital anxiety and depression scale ( HAD) were randomly divid-ed into regular treatment group and Deanxit treatment group.Clinical efficacy, symptom score, and anxiety and depression score were observed after one week, four weeks, and eight weeks.Results Deanxit signifi-cantly increased the clinical efficacy after one week ( P <0.01) and remission rate after one week ( P <0.05), four and eight weeks ( P <0.01).It improved symptoms, depression, and anxiety, which showed significant differences ( P <0.01) compared to control group after one week, four and eight weeks adminis-tration.Conclusions Deanxit can be applied in NERD with anxiety and depression treatment, which has quick effect and high remission rate, and improve patient's reflux symptoms and anxiety depression.

Objective:To compare the early outcome of proximal femoral nail antirotation (PFNA) and bipolar hemiarthroplasty in treatment of intertrochanteric fractures in elderly patients aged 90 years or more.Methods:A retrospective case-control study was conducted to analyze the clinical data of 43 elderly patients aged 90 years or more with intertrochanteric fractures admitted to Henan Provincial People's Hospital from January 2017 to June 2018. There were 12 males and 31 females, aged 90-102 years [(92.3±2.5)years]. A total of 31 patients were treated by PFNA (PFNA group) and 12 patients by bipolar hemiarthroplasty (hemiarthroplasty group). Comparisons were made between the two groups in terms of operation time, intraoperative blood loss, time of weight bearing after operation, rate of blood transfusion, incidence of complications 2 weeks and 3 months after operation, Harris score 12 months after operation and mortality 12 months after operation.Results:All patients were followed up for 1-30 months [(19.1±9.8)months] in PFNA group and for 0.5-29 months [(18.6±10.6)months] in hemiarthroplasty group. Operative time was (95.8±31.0)minutes in PFNA group, shorter than (128.8±40.5)minutes in hemiarthroplasty group ( P<0.05). Intraoperative blood loss was (71.3±25.7)ml in PFNA group and (212.5±113.1)ml in hemiarthroplasty group ( P<0.05). Time of weight bearing after operation was (43.9±31.9)days in PFNA group, longer than (5.9±2.8)days in hemiarthroplasty group ( P<0.05). The perioperative blood transfusion rate in PFNA group (29%) was less than hemiarthroplasty group (75%) ( P<0.05). Incidence of complications 2 weeks after operation was similar between PFNA group (23%) and hemiarthroplasty group (42%) ( P>0.05). Incidence of complications 3 months after operation in PFNA group was 26%, similar with 42% in hemiarthroplasty group ( P>0.05). Harris score 12 months after operation in PFNA group was (56.3±32.3)points, comparable to (59.3±36.7)points in hemiarthroplasty group ( P>0.05). Mortality rate 12 months after operation was 19% in PFNA group and 25% in hemiarthroplasty group ( P>0.05). Conclusion:For intertrochanteric fractures in elderly patients aged 90 years or more, PFNA and bipolar hemiarthroplasty are both effective treatments, but PFNA may be a better choice with shorter operation time and less intraoperative blood loss.

Objective To analyze the infiltration of inflammatory cells under the mucosa of female cystitis glandularis and the different inflammatory infiltration in different clinical pathological types of cystitis glandularis.Methods Immunohistochemical method was used to detect the bladder mucosal tissue samples of 10 female patients confirmed cystitis glandularis admitted from June 2016 to October 2016.The results of immunohistochemical staining were collected and statistically analyzed by the automatic microscopy and image analysis system.In addition,the clinical data and tissue sample of 49 cases of cystitis glandularis treated from December 2006 to August 2017 were collected.Age of 49 patients was (34.4 ±7.5) years old and BMI was (21.9 ± 4.2) kg/m2.There were 19 cases of hypertension and 18 cases of diabetes.According to the cystoscopic manifestations,follicular edema type,papilloma type,and intestinal adenomatosis type were defined as high risk.Chronic inflammatory type and mucosa unchanged type were defined as low risk.Immunohistochemical staining was used to detect tissue samples,to compare the general data of different types of cystitis glandularis and the degree of infiltration of bladder mucosal inflammatory cells.Results T lymphocytes were highly expressed in 10 patients,and B lymphocytes and plasma cells were not expressed or extremely low (P ＜ 0.01).Of the 49 patients,29 were high risk type cystitis glandularis (follicular edema type,papilloma type,and intestinal adenomatosis type),and 21 were low risk type (chronic inflammatory type and mucosa unchanged type).The age of the high-risk group was (34.4 ± 7.5) years old with BMI of (21.9 ±4.2) kg/m2,8 cases of hypertension and 8 cases of diabetes.The age of the low-risk group was (38.2 ±8.5) years old with BMI of (20.8 ±4.0) kg/m2,11 cases of hypertension and 10 cases of diabetes.There was no statistically significant difference between two groups (P ＞ 0.05).The OABSS of high-risk group(10.4 ± 2.6) was significantly higher than that of low-risk group (7.1 ± 2.1,P ＜ 0.01).QOL of high-risk group (4.9 ± 0.9) was significantly higher than that of low-risk group (4.1 ± 0.8,P ＜ 0.01).Qmax of high-risk group was (11.4 ± 3.6) ml/s,significantly lower than that of low-risk group[(15.8 ±3.8) ml/s,P ＜0.01].The positive number of T lymphocytes of high-risk group was (173.5 ± 26.8),which was significantly higher than that of low-risk group(119.5 ± 21.2,P ＜ 0.01).Conclusions T lymphocytes infiltration is the major phenomenon in bladder submucosa of female patients with cystitis glandularis.The inflammatory infiltration by T lymphocytes could be associated with patient's symptom and bladder's pathological changes.

Objective:To investigate the tumor suppressing effect of Shenqi Yiliu decoction combined with cisplatin via ERK-mediated C-Myc/PD-L1 phase-coordinated pathway on H22 hepatocellular carcinoma tumor-bearing mice and its mechanism.Meth-ods:In 60 SPF-grade male Kunming mice,10 mice were taken as blank group by random number table method,and the other 50 mice were replicated as H22 hepatocellular carcinoma tumor-bearing mouse model.After successful replication of the model,the model mice were randomly divided into model group,cisplatin group[2.5×10-3 g/(kg·3 d)],Shenqi Yiliu decoction low[13.515 g/(kg·d)],me-dium[27.03 g/(kg·d-1)],and high dose[27.030 g/(kg·d)]combined with cisplatin group[2.5×10-3 g/(kg·3 d)],10 mice in each group were treated for 13 d.After 24 h of the last dose,the mice were anesthetized and sacrificed,and the tumor inhibition rate,spleen index and thymus index of each drug group were determined;HE staining was performed to observe the histopathological changes of tumor in mice;ELISA kit was used to detect the contents of EGF and IFN-γ in tumor tissue homogenate;p-ERK1/2,C-Myc and PD-L1 protein expression in tumor tissue were detected by IHC and Western blot;ERK,C-Myc and PD-L1 mRNA expression levels in tumor tissue were detected by RT-PCR.Results:Compared with blank group,the average body mass and spleen index of mice in model group were decreased(P<0.05).Compared with model group,the tumor inhibition effect of each treatment group was obvious,and Shenqi Yiliu decoction combined with cisplatin group inhibited tumor growth in liver cancer mice in a dose-dependent way,im-proved the average body mass,spleen index and thymus index of mice,promoted the necrosis of tumor cells and increased the necrotic area.EGF and IFN-γ contents,P-ERK1/2,C-Myc,PD-L1 protein expressions and ERK,C-Myc,PD-L1 mRNA expression levels were decreased in tumor tissues(P<0.05).Compared with cisplatin group,the therapeutic effect of Shenqi decoction combined with cisplatin in medium and high dose groups was significant,and the difference was statistically significant(P<0.05).Conclusion:Shenqi Yiliu decoction combined with cisplatin effectively inhibited the tumor growth of H22 liver cancer tumor-bearing mice and significantly reduces the expression of C-Myc and PD-L1 proteins in the tumor tissues,which may be through the regulation of ERK signaling path-way-related protein expression to exert tumor suppressive effect.
