Objective:To determine if growth hormone (GH) and glutamine (Gln) reduce the time and dose of parenteral nutrition (PN) in patients with short bowel syndrome. Methods: Sixteen PN-dependent patients with short bowel syndrome were randomly assigned to Group A (control, oral Gln [0.6 g/kg/d] + GH placebo + diet, n= 5), B (Gln placebo + GH [8 IU/d] + diet, n= 5), and C (Gln + GH + diet, n= 6). PN volume and content were determined by standard criteria based on clinical measurements. After 4 weeks, GH and GH placebo were discontinued, but the diet with Gln or Gln placebo was continued for 12 weeks. Results: Group B showed greater reductions in PN volume, PN calorie and PN frequency than Group A (P

Objective To explore the application value of end-to-side closed in situ pancreaticojejunostomy in pancreaticoduodenectomy.Methods The clinical data of 22 patients with obstructive jaundice who were admitted to the Second Affiliated Hospital of Harbin Medical University from January to March 2014 were retrospectively analyzed.All the patients were explored whether tumors invaded inferior vena cava, superior mesenteric vein and portal vein after gallbladder decompression under general anesthesia by tracheal intubation.The standard or extended pancreaticoduodenectomy was applied according to the intraoperative results.The method of pancreaticojejunostomy was end-to-side closed in situ anastomosis of pancreatic duct and jejunal seromuscular layer.The operation time, intraoperative blood loss, postoperative gastrointestinal function recovery time, amylase concentration of drainage at postoperative day 1,3,5, postoperative complication, pathological classification and duration of hospital stay were observed.Patients were followed up by outpatient examination and telephone interview till May 2014.The out-patient follow-up included color Doppler ultrasound examination of effusion near the pancreatic stump, and the telephone interview included whether there were diarrhea of exocrine pancreatic insufficiency.Measurement data with normal distribution were presented as-x ± s (range) , and measurement data with skewed distribution as M(range).Results All the 22 patients underwent successfully the operation, including 17 undergoing standard pancreaticoduodenectomy and 5 undergoing extended pancreaticoduodenectomy, with end-to-side closed in situ anastomosis of pancreatic duct and jejuna seromuscular layer.The operation time of pancreaticoduodenectomy and end-to-side closed in situ pancreaticojejunostomy were (313 ± 37)minutes (range, 228-360 minutes) and(13 ± 4) minutes (7-22 minutes) , respectively.The intraoperative blood loss was (400 ± 207) mL (range, 100-800 mL).The mean tumor size was 3.69 cm2(range, 0.72-1.68 cm2).The recovery time of gastrointestinal function was (5 ±2)days (range, 4-7 days).The serum amylase at postoperative day 1, 3, 5 in the 21 patients was (145±30)U/L (range, 116-180 U/L), (136±40)U/L (range, 105-176 U/L), (147 ±38)U/L(range, 110-175 U/L), and the drainage amylase was (220 ±56)U/L (range, 172-289 U/L), (240 ±54)U/L (range, 192-300 U/L) , (245 ± 52) U/L (range, 190-298 U/L) , respectively.The serum amylase at postoperative day 1, 3, 5 in the patient with pancreatic fistula was 156 U/L, 178 U/L and 177 U/L, and the drainage fluid amylase was 500 U/L, 620 U/L and 605 U/L, respectively.There was 1 patient in the 22 patients with pancreatic duct stent and without death.Among the 4 patients with postoperative complications, 1 patient with grade A postoperative pancreatic fistula recovered after continuous external drainage, the other 3 including 1 case of infection,1 case of pneumonia and 1 of stress ulcer bleeding also recovered after symptomatic and supportive treatment.Postoperative pathological examinations of the 22 patients showed 12 cases of ductal adenoeareinoma, 2 of neuroendocine tumors, 1 of simple cyst, 1 of cystadenocarcinoma, 1 of squamous carcinoma, 1 of adenocarcinoma, 1 of ampullary carcinoma, 1 of tubular adenoma, 1 of leiomyoma and 1 of atypical intraductal hyperplasia.The average length of hospital stay was (11 ±3)days (range, 2-15 days).There were no effusion near the pancreatic stump showed in color Doppler ultrasound examination and diarrhea of exoerine pancreatic insufficiency.Conclusion End-to-side closed in situ pancreaticojejunostomy is safe and feasible, and can be applied to any pancreatic duct size and texture.

Objective To evaluate the therapeutic effect of transarterial chemoembolization (TACE) combined with CT-guided 125I seed implantation in treating hepatocellular carcinoma (HCC) complicated by portal vein tumor thrombus(PVTT), and to discuss the technical points. Methods A total of 48 HCC patients with PVTT were enrolled in this study. TACE combined with CT-guided 125I seed implantation was carried out in all 48 patients. Based on the sites of PVTT, the lesions were classified into type A (PVTT within main portal vein), type B(PVTT within level-1 portal branch) and type C(PVTT within level-2 or more distal portal branch). According to whether the 125I seeds were directly implanted into the PVTT or not, the patients were divided into direct in-tumor thrombus implantation group (group A) and around tumor thrombus implantation group (group B; the 125I seeds were implanted in the liver parenchyma or in tumor tissue around the tumor thrombus within 1.7 cm region). The tumor thrombus control rate(TTCR), the disease control rate(DCR), the time to progress(TTP) and the overall survival rate of patients(OS) were determined, and the results were compared among different types and groups. Results TACE combined with CT-guided 125I seed implantation was successfully accomplished in all 48 patients. The median OS of type A, B and C was 8, 11.5 and 15 months respectively(P=0.003);the TTCR of type A, B and C was 61.5%, 70.8%and 72.7%respectively(P=0.548); the DCR of type A, B and C was 69.2%, 75%and 81.8% respectively (P=0.483); the median TTP of type A, B and C was 4.5, 8 and 11 months respectively(P=0.030);the median TTP of intra-hepatic tumor of type A, B and C was 5, 9 and 9.5 months respectively(P=0.012). The median OS in group A and group B was 10 and 11.5 months respectively (P=0.239); the TTCR in group A and group B was 69.2% and 68.2%respectively(P=0.591); the DCR of intra-hepatic tumor in group A and group B was 73.1% and 77.3%respectively(P=0.502); the median TTP of tumor thrombus in group A and group B was 7 and 10 months respectively(P=0.276); and the median TTP of intra-hepatic tumor in group A and group B was 8 and 9.5 months respectively(P=0.089). Conclusion For the treatment of hepatocellular carcinoma complicated by portal vein tumor thrombus, TACE combined with CT-guided 125I seed implantation can effectively control the progress of both the tumor thrombus and the intra- hepatic tumor and prolong patient’s survival time. Implantation of 125I seeds into the portal vein tumor thrombus and implantation of 125I seeds into the liver parenchyma around the tumor thrombus have the same therapeutic results.

Methods: Data of viral hepatitis cases in Yuxi City from 2004 to 2022 were retrieved from the China Disease Prevention and Control Information System. The temporal, human and spatial distribution of viral hepatitis cases were analyzed using a descriptive epidemiological method, and the trends in incidence of viral hepatitis were evaluated in Yuxi City from 2004 to 2022 using annual percent change (APC) and average APC (AAPC). Results: A total of 37 430 viral hepatitis cases were reported in Yuxi City from 2004 to 2022, with an average annual incidence rate of 91.27/105, and the incidence showed a tendency towards a rise (AAPC=12.686, P<0.05). There were 29 229 cases with hepatitis B, 5 796 cases with hepatitis C, 1 451 cases with hepatitis A, 520 cases with hepatitis E and 434 cases with unclassified hepatitis reported in Yuxi City, with average annual incidence rates of 71.27/105, 14.13/105, 3.54/105, 1.27/105 and 1.06/105, respectively. The average annual incidence rates of viral hepatitis were 98.24/105 and 78.94/105 among men and women, which both appeared a tendency towards a rise (AAPC=12.415% and 12.581%, both P<0.05). The highest average annual incidence of viral hepatitis was seen among residents at age of 25 to 29 years (139.89/105), with the lowest seen among residents at ages of 0 to 4 years (11.38/105), and the average annual incidence of viral hepatitis appeared a tendency towards a rise with age (P<0.05). The highest average annual incidence of viral hepatitis was seen in Huaning County (234.24/105), with the lowest seen in Chengjiang City (26.11/105), and the average annual incidence appeared a tendency towards a rise in Xinping County from 2004 to 2022 (AAPC=21.451%, P<0.05). Conclusions The reported incidence of viral hepatitis appeared a tendency towards a rise in Yuxi City from 2004 to 2022, with hepatitis B as the main type. High incidence was seen among men and adolescents. The viral hepatitis control strategy requires to be adjusted with adaptations to high-incidence hepatitis subgroups, residents and regions.

Objective To investigate the value of X-ray guided desmopressin (DDAVP) stimulated bilateral inferior petrosal sinus sampling (IPSS) in diagnosing the recurrence of ACTH dependent Cushing disease or ineffectiveness after surgery or radiotherapy. Methods Retrospective analyses of patients with recurrent ACTH dependent Cushing disease (31 cases) or ineffective (3 cases) treatment after surgery or radiotherapy from January 2013 to October 2014 in our hospital was conducted. Bilateral inferior petrosal sinus angiography showed the same side of the cavernous sinus to prove successful intubation. The cases with discontinuous of the inferior petrosal sinus and cavernous sinus were excluded by this study. Finally, there were 34 cases of the patients in this study. Diagnosis was based on the ratio of ACTH level in IPS to peripheral vein after desmopressin test.The gradient≥2 at baseline or gradient≥3 after desmopressin test suggested the sources were in the pituitary. Diagnosis was confirmed by gold standard to investigate the value of X-ray guided desmopressin (DDAVP) stimulated bilateral IPSS. Results The IPS gradient≥2 at baseline or gradient≥3 after desmopressin test suggested the sources were in the pituitary in 30 patients. A total of 22 (22/30) patients underwent surgery with a final diagnosis of ACTH adenoma. The symptoms were obviously relieved in 8 (8/30) cases after sellar area gamma knife treatment and lesions were confirmed in the pituitary. IPS gradient<2 at baseline or gradient<3 after desmopressin test was found in 4 cases. One case (1/4) was found to have for ACTH adenoma after pituitary surgery. The other 3 cases (3/4) were confirmed to have lung carcinoid and clinical symptom alleviated after surgery. The sensitivity of desmopressin stimulated IPSS was 96.8%, the specificity was 100%, and the accuracy was 97.1%. Conclusion Desmopressin stimulated IPSS is an effective diagnostic procedure in diagnosing ACTH dependent Cushing disease recurrence or ineffectiveness after surgery or radiotherapy.

Objective:To investigate the expression difference of miR-3189-3p in renal cancer tissue and adjacent tissue and its effect on the biological function of renal cancer cells.Methods:quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression level of miR-3189-3p in renal cancer tissues and adjacent tissues, renal cancer cell lines (Caki-1, ACHN, A498, OS-RC-2) and normal renal tubular epithelial cells HK-2. miR-NC or miR-3189-3p mimics were transfected into renal cancer cells with the lowest expression of miR-3189-3p, respectively, named miR-NC group and miR-3189-3p group. The effects of miR-3189-3p on the proliferation and invasion of renal cancer cells were detected by CCK-8 method and Transwell migration experiment. miRanda and miRTarBase software was used to predict the downstream gene of miR-3189-3p. The dual luciferase reporter gene experiment was used to verify the downstream gene of miR-3189-3p. qRT-PCR and Western blotting were used to detect the expression of miR-3189-3p downstream gene. Measurement data were expressed as mean ± standard deviation ( ± s), and t-test was used for comparison between groups. Results:The relative expression of miR-3189-3p in renal cancer tissue and paracancerous tissue was 1.97±0.61 and 6.19±0.73, respectively, and the relative expression of miR-3189-3p in renal cancer tissue was lower than that in paracancerous tissue ( P<0.01). The relative expression of miR-3189-3p in renal cancer cell lines was lower than that in HK-2 cells ( P<0.05). The relative expression of miR-3189-3p in OS-RC-2 cells was the lowest ( P<0.01). The relative expression levels of miR-3189-3p in OS-RC-2 cells in the miR-NC group and miR-3189-3p group were 1.01±0.11 and 9.27±1.43, respectively, and the relative expression levels of miR-3189-3p in the miR-NC group significantly lower than the miR-3189-3p group ( P<0.01). Compared with the miR-NC group, the proliferation ability of OS-RC-2 cells with high expression of miR-3189-3p was significantly reduced ( P<0.05). The numbers of penetrating cells in the miR-NC group and miR-3189-3p group were 165.40±17.02 and 41.07±6.36, respectively, and the invasive ability of OS-RC-2 cells in the miR-3189-3p group was significantly reduced ( P<0.01). The target gene of miR-3189-3p is Aquaporin 3 ( AQP3) and miR-3189-3p can target AQP3 mRNA ( P<0.01). Compared with the miR-NC group, the expression of AQP3 gene in the high-expressing miR-3189-3p cells was significantly reduced at both the mRNA level and the protein level ( P<0.01). Conclusions:The expression of miR-3189-3p is down-regulated in renal cell carcinoma. High expression of miR-3189-3p can significantly inhibit the proliferation and invasion of renal cell carcinoma OS-RC-2 cells. The molecular mechanism is that miR-3189-5p targets and inhibits the expression of AQP3 gene.
