Abstract
OBJECTIVES To observe the therapeutic effect of electroacupuncture (EA) on neurogenic urinary retention rats, so as to explore the underlying mechanism of EA in treating neurogenic urinary retention by focusing on 3-phosphoinositide-dependent protein kinase 1 (PDK1)/protein kinase B (Akt)/hyperpolarization activated cyclic nucleotide-gated cation channel 4 (HCN4) pathway. METHODS Female SD rats were randomly divided into sham operation, model, EA, PDK1 inhibitor, HCN4 blocker and EA + HCN4 blocker groups, with 20 rats in each group. The model of sacral spinal cord injury was established by modified Hassan Shaker spinal cord transection method. EA (2 Hz/15 Hz, 0.5 mA) was applied to "Zhongji" (CV3) and "Zhongliao" (BL33) for 20 min, once daily for 10 days. Rats of the PDK1 inhibitor group received intraperitoneal injection of OSU-03012 (20 mg/kg), and rats of the HCN4 blocker group received intraperitoneal injection of ivabradine (10 mg/kg), both once every other day for 10 days. The urodynamic indexes of rats were detected by multi-channel physiological recorder;muscle strip test was used to detect detrusor excitability;the morphological changes of bladder were observed by HE staining. Immunofluorescence double staining was used to detect the co-expression of HCN4 and C-Kit, a specific marker of interstitial cells of Cajal in bladder. Western blot was used to detect the expression of PDK1/Akt/HCN4 pathway proteins in bladder tissue and heat shock protein 27 (HSP27), a protein related to bladder contraction function. RESULTS Compared with the sham operation group, the rats in the model group showed urinary dysfunction, decreased leak point pressure, isolated detrusor spontaneous contraction frequency, fluorescence intensity of C-Kit positive cells, HCN4+/C-Kit+ co-expression, HCN4 and p-HSP27/HSP27 protein expression in bladder tissue (P<0.05), and increased maximum bladder capacity and comp-liance, minimum tension during contraction of isolated detrusor, PDK1 and p-Akt/Akt protein expression in bladder tissue (P<0.05). Meanwhile, the above index were all reversed after EA and PDK1 inhibitor intervention (P<0.05). In comparison with the EA group, the rats had severe urinary dysfunction, the urine leakage point pressure, spontaneous contraction frequency, fluorescence intensity of C-Kit positive cells, the co-expression of HCN4+/C-Kit+, and the protein expression of HCN4 and p-HSP27/HSP27 were decreased (P<0.05), the maximum bladder capacity and compliance, the minimum tension during contraction of isolated detrusor, and the protein expression of PDK1 and p-Akt/Akt in bladder tissue were increased (P<0.05) in both HCN4 blocker and EA+HCN4 blocker groups. HE staining showed exfoliated bladder epithelium and disordered layers, vacuolization of bladder wall cells, with infiltration of neutrophils in mucosal and muscular layers in the model group, which were relatively milder in the EA and PDK1 inhibitor groups, but worse in the HCN4 blocker and EA + HCN4 blocker groups. CONCLUSIONS EA can improve the urinary dysfunction in rats with neurogenic urinary retention, which may be related to its effect in inhibiting the activation of PDK1/Akt pathway, promo-ting HCN4-mediated detrusor excitatory contraction and urinary electrical signal activation.

Abstract
We retrospectively analyzed 17 patients with esophageal stent who underwent cervical esophageal and/or hypopharyngeal stenosis after total laryngectomy (TL) from January 2014 to January 2018. The success rate of stent implantation was 100%. Dysphagia in 16 patients improved to class 0 or 1 (16/17, 94.12%) after stent implantation and in 1 patient was improved to class 2 (1/17, 5.88%). Two patients died of tumor progression at 7 months and 11 months after stent implantation, respectively, but both could eat semi-solid/solid food before death. Dysphagia was resolved in the remaining 15 patients, and there was no recurrence of dysphagia including feeding obstruction during follow-up. Therefore, this case series concludes that the esophageal stent position after TL can be much higher than that of patients with normal pharyngeal structures. Esophageal stent implantation is a feasible and effective treatment for patients with laryngopharyngeal/esophageal stenosis following TL.

Abstract
BACKGROUND Transjugular intrahepatic portosystemic shunt (TIPS) is currently used for the treatment of complications of portal hypertension. The incidence of hepatic encephalopathy (HE) remains a problem in TIPS placement. It has been reported that the right branch mainly receives superior mesenteric venous blood while the left branch mainly receives blood from the splenic vein. We hypothesized that targeted puncture of the left portal vein would divert the non-nutritive blood from the splenic vein into the TIPS shunt; therefore, targeted puncture of the left branch of the intrahepatic portal vein during TIPS may reduce the risk of HE.
AIM To evaluate the influence of targeted puncture of left branch of portal vein in TIPS on HE.
METHODS A retrospective analysis of 1244 patients with portal-hypertension-related complications of refractory ascites or variceal bleeding who underwent TIPS from January 2000 to January 2013 was performed. Patients were divided into group A (targeting left branch of portal vein, n = 937) and group B (targeting right branch of portal vein, n = 307). TIPS-related HE and clinical outcomes were analyzed.
RESULTS The symptoms of ascites and variceal bleeding disappeared within a short time. By the endpoint of follow-up, recurrent bleeding and ascites did not differ significantly between groups A and B (P = 0.278, P = 0.561, respectively). Incidence of HE differed significantly between groups A and B at 1 mo (14.94% vs 36.80%, χ2 = 4.839, P = 0.028), 3 mo (12.48% vs 34.20%, χ2 = 5.054, P = 0.025), 6 mo (10.03% vs 32.24%, χ2 = 6.560, P = 0.010), 9 mo (9.17% vs 31.27%, χ2 = 5.357, P = 0.021), and 12 mo (8.21% vs 28.01, χ2 = 3.848, P = 0.051). There were no significant differences between groups A and B at 3 years (6.61% vs 7.16%, χ2 = 1.204, P = 0.272) and 5 years (5.01% vs 6.18%, χ2 = 0.072, P = 0.562). The total survival rate did not differ between groups A and B (χ2 = 0.226, P = 0.634, log-rank test).
CONCLUSION Targeted puncture of the left branch of the intrahepatic portal vein during TIPS may reduce the risk of HE but has no direct influence on prognosis of portal-hypertension-related complications.

Abstract
AIM: To evaluate the clinical efficacy of agitation thrombolysis via transjugular access for the treatment of acute portal vein thrombosis.
METHODS: Thirteen patients with acute portal vein thrombosis treated from October 2012 to March 2015 at our hospital were analyzed retrospectively. The portal vein was approached via the transjugular intrahepatic portosystemic route, followed by agitation thrombolysis to resolve the thrombi. The need for transjugular intrahepatic portosystemic shunt (TIPS) was based on the presence of portal hypertension, and then a catheter was indwelled into the thrombi. The success rate, thrombolytic therapeutic time and effect, and complications were observed. Computed tomography and Doppler ultrasound were performed to follow the patency of the portal vein and TIPS stent.
RESULTS: Agitation thrombolysis were successfully created in 12 patients. Of 8 patients who underwent TIPS, 1 underwent wide resection due to confirmed extensive intestinal necrosis on postoperative day 2; however, the patient died 9 d later. In the remaining 11 patients, the portal vein was recanalized > 90% as revealed by CT findings. There was a significant difference in lumen occupancy between pre- and post-operation (P < 0.01). The clinical symptoms such as abdominal pain, ascites, and gastrointestinal bleeding were all relieved or disappeared. The complications were mainly as follows: intraoperative subcapsular bleeding in one patient; death due to intestinal necrosis in one patient; hepatic encephalopathy at 3 mo in one patient with TIPS; and hematuria during thrombolysis in one patient. During follow-up, TIPS stent stenosis was noted in one patient at 7 mo and treated by balloon angioplasty.
CONCLUSION: Agitation thrombolysis via transjugular access for the treatment of acute portal vein thrombosis is safe and effective.

Abstract
Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) has been identified as a potential cancer biomarker, yet the mechanism by which it influences the development of cancer remains unknown. In this study, we aimed to correlate MALAT1 expression with pathological features and prognosis in cancer patients. Several databases were searched using combinations of keywords relating to MALAT1 and cancer. After selection of relevant cohort studies according to strict criteria, a meta-analysis was conducted. Twelve studies were analyzed, involving 958 cancer patients. Elevated MALAT1 expression was associated with poor prognosis and larger tumors [prognosis: hazard ratio = 3.11, 95% confidence interval (CI) = 1.98-4.23, P = 0.000; tumor size: odds ratio (OR) = 0.40, 95%CI = 0.21-0.74, P = 0.003]. However, no connection with histological grade, T-stage, lymph node (LN) metastasis, or distant metastasis was established (all P > 0.05). A correlation between increased expression and poor prognosis was observed in the large and small sample-size subgroups (all P< 0.05), as was a relationship with large tumor size (OR = 0.30, 95%CI = 0.13-0.71, P = 0.006). Expression was correlated with T-stage and distant metastasis in the small sample-size subgroup (all P < 0.05), but no association was detected regarding histological grade, LN metastasis in either subgroup (all P > 0.05). Our findings demonstrate that elevated MALAT1 expression correlates with large tumor size, advanced tumor stage, and poor prognosis, and might therefore be utilized to evaluate clinical pathological features and prognostic out come for cancer patients.

Abstract
Using the FDD-PCR technique, ten new fiber-specific cDNAs were isolated from developing cotton fiber cells and showed high amino acid identity to previously recorded cDNAs. Five cDNAs encoding bisphosphate nucleotidase, alpha-tubulin, beta-galactosidase, annexin, and reversibly glycosylated polypeptide were identified while the functions of five other cDNAs were undetermined. Dot blot analysis showed that all transcripts of the 10 cDNAs accumulated preferentially in fiber cells and the majority were expressed in the early phase of cotton fiber development, except for F14 which accumulated at a high level during the late phase of developing fiber cells, indicating that all of the genes were involved in the process of fiber development.

Abstract
Interleukin-1 (IL-1) is a cytokine with diverse biological activities. It can serve as a fibroblast (FB) growth factor which involves in the development of pulmonary fibrosis. IL-1 receptor antagonist (IL-1ra) can compete with IL-1 for occupancy of surface receptors of target cells without agonist effect. In order to find a new method to treat pulmonary fibrosis, we investigated the effect of recombinant human IL-1ra on the development of pulmonary fibrosis by evaluating collagen content, histological change, and TGF-beta mRNA expression in the rats bleomycin-induced pulmonary fibrosis. The results indicate are that there are no significant difference between the IL-1ra treated group and the control group.
