Objective To investigate the clinical diagnostic and differential diagnostic values of antisense non-coding RNA in the INK4 locus (ANRIL) and tumor suppressors (p14ARF, p15INK4b and p16INK4a) mRNA expression levels in peripheral blood lymphocytes of patients with cirrhosis and hepatocellular carcinoma. Methods The patients with hepatocellular carcinoma and cirrhosis admitted in Shantou Central Hospital from October 2013 to April 2014 were selected. The real-time quantitative reverse transcription-polymerase chain reaction (RT-qPCR) was used to detect ANRIL, p14ARF, p15INK4b and p16INK4a mRNA expression levels of peripheral blood lymphocytes. The subjects having taken physical health examinations in outpatient clinics were assigned in the healthy control group. Results During the study period, 19 cases of hepatocellular carcinoma, 24 cases of cirrhosis, and 31 healthy controls were finally enrolled. In the hepatocellular carcinoma group, the mRNA expression level of ANRIL was significantly higher than that of the healthy control group (?Ct:13.07±0.62 vs. 12.45±0.84, P<0.01), while p15INK4b mRNA expression level was obviously lower than that of the healthy control group (13.24±0.98 vs. 13.99±0.99, P<0.05). But there were no significant differences in the mRNA expression levels of ANRIL (13.07±0.65 vs. 12.71±0.76) and p15INK4b (13.24±0.98 vs. 13.55±1.08) between the groups of hepatocellular carcinoma and cirrhosis (both P>0.05). There were also no statistically significant differences in p14ARF and p16INK4a mRNA expressions among the three groups (all P>0.05). Conclusion The elevation of ANRIL and descent of p15INK4b mRNA expression levels in peripheral blood lymphocytes in patients with liver lesion can be used as the reference indicators for the early diagnosis of hepatocellular carcinoma and to predict their prognoses.

OBJECTIVE:To investigate the therapeutic effect of Lipo-prostaglandin E 1 (Lipo PGE 1 )on chronic severe type B hepatitis by MELD(Model for end-stage live disease)prognosis analysis.METHODS:Of a total of115cases with chronic severe type B hepatitis,57were randomly assigned to receive a common combined therapy and58to receive a common combined therapy plus Lipo PGE 1 for4weeks,the MELD score and prognosis of diseases of the2groups were assessed.RE-SULTS:The MELD score in the treatment group(20.12?8.97)was lower than that of the control group(24.76?10.41)after4weeks’treatment(P

Objective:To review the experience of closure of the left-main-bronchial stump fistula using endoscopic liner cutter staplers through the right thoracic approach and I stage or staged treatment for the left pyothorax.Methods:6 patients with the left-main-bronchial stump fistula after left pneumonectomy combined with pyothorax were treated by closing the left-main-bronchial stump using endoscopic liner cutter staplers through the right thoracic approach, and pleura was used to cover the distal and proximal incisional margin of the stump respectively. The thoracic T-tube drainage was used in the I stage or staged treatment for the left pyothorax.Results:All patients were survived without recurrence of the bronchopleural fistula. 4 patients were observed to have no recurrence of pyothorax when 1 patient had recurrence of pyothorax and was treated with intermittent T-tube drainage.1 patient operated with left-thoracic fenestration in the past was treated with drainage waiting for secondary operation.Conclusion:The right thoracic approach seemed to be a safer and more effective method than the transsternal transpericardial approach in cases with the left-main-bronchial stump fistula combined with pyothorax. The use of endoscopic liner cutter staplers reduced the risk of bleeding, infection and recurrence of fistula. The T-tube drainage in the I stage or staged treatment for the left pyothorax was considered to be an easier way for treatment.

Objective:To summarize the experience of surgical methods without repairing the fistula for 92 cases with gastrointestinal intrathoracic fistula.Methods:The surgical methods without repairing the fistula were performed through VATS, small incision assisted with VATS or thoracotomy. The focus of the surgery was to promote lung expansion, eliminate the residual cavity of chest cavity and keep effective drainage. After entering the chest cavity from the affected side, wash chest cavity with a large amount of warm normal saline and sterilize intermittently with iodophor to ensure the sterile environment in the pus cavity. Then completely remove the pleural cellulose or fiberboard on visceral pleura to promote lung expansion, eliminate the residual cavity of the chest cavity. The fistula was covered tightly and supported firmly by the visceral pleura on the lung. Multiple T-tubes were placed in thoracic cavity and fistula to keep effective postoperative drainage.Results:Among 92 cases, 85 cases were cured and the cure rate was 92.4% (85/92).7 cases died and the mortality rate was 7.61% (7/92). The 7 dead cases include 5 cases with esophagogastric anastomotic fistula (the death of 3 cases was cause by aortic esophagogastric fistula, the death of 1 case was cause by thoracic gastric tracheal fistula and 1 case was dead because of pulmonary infection and respiratory failure), 1 case with esophageal rupture (the cause of death was septic shock ), and 1 case with esophageal perforation(the cause of death was pulmonary infection and respiratory failure).Conclusion:Most of the surgeries without repairing gastrointestinal intrathoracic fistula are conducted simply through VATS or small incision assisted with VATS., which is safe and effective.

Objective: To investigate the clinico-pathological characteristics, outcomes and their predictors in malignant hypertension related kidney injury with and without primary glomerular diseases. Methods: Patients with clinical diagnosis of malignant hypertension, biopsy-proven kidney injury caused by malignant hypertension and complete clinical data from January 2010 to December 2018 were retrospectively analyzed. According to clinical and renal pathology, patients were divided into malignant hypertension related kidney injury without primary nephropathy group and with primary nephropathy group. Clinico-pathological characteristics and outcomes were evaluated and compared between malignant hypertension related kidney injury with and without primary glomerular diseases. Results: Totally 31 biopsy-proven kidney injury patients were analyzed. Among them, there were 18 cases with primary glomerular diseases and 13 cases without primary glomerular diseases, with age of (32.5±6.5) years old and (34.7±8.1) years old, respectively. There were 12 males in both group. The proportion of primary IgA nephropathy was higher (16/18) in the group of malignant hypertension related kidney injury with primary glomerular diseases. Malignant hypertension with primary glomerular diseases patients had lower plasma albunin level [(32.7±6.4) g/L vs (38.5±7.3) g/L, P=0.027], higher 24-hour proteinuria level [(4.03±2.71) g vs (1.45±0.98) g, P=0.002] and higher incidence rates of dysmorphic hematuria (14/18 vs 0, P=0.001) than those without primary glomerular diseases patients. Glomerular sclerosis, mesangial proliferation, tubular atrophy and interstitial fibrosis were more severe in malignant hypertension with primary glomerular diseases patients (all P<0.05), but the ischemic wrinkling of glomerular capillary was more severe in malignant hypertension without primary glomerular diseases (P<0.01). There were no differences of acute or chronic malignant hypertensive injury in small artery and in afferent arterioles between the two groups. Cox regression analysis showed that loss of brush-border with flattening of tubular epithelium was the predictor for renal partial recovery (HR=5.956, 95% CI 1.198-29.614, P=0.029). Kaplan-Meier analysis showed that malignant hypertension patients with primary glomerular diseases had shorter renal survival time than those without primary glomerular diseases [(24.1±9.3) months vs (56.6±12.4) months], and accumulative renal survival rate of malignant hypertension patients with primary glomerular diseases was lower than that without primary glomerular diseases (11.6% vs 53.3%, Log-rank χ²=5.022, P=0.025). Multivariate Cox regression analysis showed that severe tubular atrophy and interstitial fibrosis were independent risk factors for end-stage renal disease in malignant hypertension patients (HR=5.870, 95% CI 1.372-25.112, P=0.017). Conclusions Malignant hypertension with primary glomerular diseases patients have more severe clinico-pathological renal impairment and poorer prognosis of long-term renal survival than those without primary glomerular diseases. Acute renal tubular injury (loss of brush-border with flattening of tubular epithelium) is the only predictor of renal function improvement in patients with malignant hypertension and renal impairment within one year. Tubular atrophy/interstitial fibrosis is a risk factor for end-stage renal disease in patients with malignant hypertension. Renal biopsy is an indispensable tool for predicting short-term and long-term renal outcomes.
