Objective To explore the value and advantage of intracranial pressure (ICP) monitoring in the treatment of hypertensive intracerebral hemorrhage (HICH) through minimally invasive surgery. Methods Seventy-three HICH cases were randomly selected and then divided into control group and treatment group. Thirty-four of them in control group received soft-channel minimally invasive hematoma removal. The head of the soft-channel was placed in the center of the hematoma. One third to half of the initial hematoma was extracted during the operation. Urokinase was injected into the soft channel to dissolve the hematoma. Thirty-nine of them in treatment group underwent the same operation procedure but with ICP monitoring to control aspirating hematoma during the operation. The target ICP was 15 mmHg. The aspiration of hematoma may stop once the ICP down to the target. Treatment such as urokinase injection was adjusted according to the value of ICP monitoring throughout the operation. The incidence of rebleeding, hematoma evacuation time and the average length of stay between two groups were compared. Results The results showed that one fifth of hematoma extracted was enough for a desired ICP. There found no rebleeding case in treatment group while 4 cases in control group and the difference had statistical significance. The hematoma evacuation time and the average length of stay between two groups had statistical significance. Conclusion Continuous ICP monitoring combined with directional software channel minimally invasive surgery changes the concept of empirically intraoperative hematoma evacuation and postoperative drug injection and proposes the idea of controlling drainage. It can shorten the course, provide sensitive and objective indicators and basis, reduce the secondary brain injury and improve prognosis.

Objectives To identify ABO blood type from a child having discrepant results in forward and reverse ABO blood grouping by serological identification and genetic testing.Methods After routine serological detection with ABO blood group,the ABO gene and ABO blood group-A subgroup genotype were tested by PCR-SSP method.Results The Serological results showed that the specimen was positive type A (anti-A:1 +w),the reverse type is O type (Ac:2 +,Bc:4 +);PCRSSP A-subtype typing showed that the genotype of the child was Ax14/O2.Conclusion Difficult blood type identification sometimes need to combine serology and molecular biology methods to confirm.In this case,the phenotype of the child was Ax,and the genotype was Ax14/O2.

Anti-angiogenic drugs (AADs), which mainly target the vascular endothelial growth factor-A signaling pathway, have become a therapeutic option for cancer patients for two decades. During this period, tremendous clinical experience of anti-angiogenic therapy has been acquired, new AADs have been developed, and the clinical indications for AAD treatment of various cancers have been expanded using monotherapy and combination therapy. However, improvements in the therapeutic outcomes of clinically available AADs and the development of more effective next-generation AADs are still urgently required. This review aims to provide historical and perspective views on tumor angiogenesis to allow readers to gain mechanistic insights and learn new therapeutic development. We revisit the history of concept initiation and AAD discovery, and summarize the up-to-date clinical translation of anti-angiogenic cancer therapy in this field.

Crohn’s disease is a chronic intestinal inflammatory disorder of unknown etiology. Although the pharmacotherapies for Crohn’s disease are constantly updating, nutritional support and adjuvant therapies have recently gained more attention. Due to advancements in clinical nutrition, various clinical nutritional therapies are used to treat Crohn’s disease. Doctors treating inflammatory bowel disease can now offer several diets with more flexibility than ever. The Crohn’s disease exclusion diet is a widely used diet for patients with active Crohn’s disease. The Crohn’s disease exclusion diet requires both exclusion and inclusion. Periodic exclusion of harmful foods and inclusion of wholesome foods gradually improves a patient’s nutritional status. This article reviews the Crohn’s disease exclusion diet, including its structure, mechanisms, research findings, and clinical applications.

Objective:To investigate the clinical advantages of absorbable barbed wires in laparoscopy combined with choledochoscopy treatment of gallbladder polyps.Methods:The clinical data of 103 patients with gallbladder polyps who received laparoscopy combined with choledochoscopy treatment in The First People's Hospital of Lianyungang from February 2016 to March 2018 were retrospectively analyzed. Sixty-five patients in the observation group underwent gallbladder wall sutures with absorbable barbed wires, and thirty-eight patients in the control group underwent gallbladder wall sutures with common absorbable wires. The operative time, gallbladder wall suture time, intraoperative blood loss, average hospitalization time, and postoperative bile leakage were compared between the two groups.Results:There were no significant differences in intraoperative blood loss and average hospitalization time between the two groups ( P = 0.312, P = 0.114). In the observation group, gallbladder wall suture time and operative time were (5.58 ± 1.14) minutes and (60.71 ± 11.03) minutes, respectively, which were shorter than (6.32 ± 1.04) minutes and (68.24 ± 9.61) minutes in the control group ( t = 3.23, 3.50, P = 0.002, 0.001). No bile leakage occurred in the observation group and bile leakage occurred in four (10.5%) patients in the control group. There was a significant difference in bile leakage between the observation and control groups ( χ2 = 4.57, P = 0.032). Conclusion:Absorbable barbed wires for gallbladder wall sutures during operation in laparoscopy combined with choledochoscopy treatment of gallbladder polyps is safe and feasible. It can markedly shorten gallbladder wall suture time and operative time, decrease the incidence of bile leakage, and has a clinical advantage over common absorbable wires.

OBJECTIVE To construct an insulin-resistant(IR)small intestinal organoid model of mice and study the protective effect of flavanomarein(FM)on the intestinal mucosal barrier in the model.METHODS ①Small intestinal organoid models of C57BL/6J and db/db of mice were constructed.The expressions of Ki-67,E-cadherin(E-cad),lysozyme(Lyz)and mucin-2(Muc-2)in small intestinal organ-oids were detected by 3D immunofluorescence.RT-qPCR was used to detect the expressions of fibro-nectin(Fn),glucagon-like peptide-1(GLP-1)and peotide YY(PYY)mRNA while Western blotting was used to detect the expressions of Fn,GLP-1 and PYY protein.The Lyz secretion level was detected by ELISA.② Small intestinal organoids were divided into five groups:C57BL/6J mice 'small intestinal organ-oids as the normal control group,db/db mice' intestinal organoids as the IR model group,db/db mice small intestinal organoids with flavanomarein 25,50 and 100 μmol·L-1 intervention for 48 h as IR model+ FM groups.RT-qPCR was used to detect the expression of Lyz mRNA while Western blotting was used to detect the expression of Lyz protein.RESULTS ① On the 6th day of small intestinal organoid culture,a ring structure with a clear luminal structure was formed and an IR mouse small intestinal organoid model was established.3D Immunofluorescence detection showed that the established small intestinal organoids all expressed Ki-67,E-cad,Lyz and MUC-2.Compared with the normal control group,the expres-sion of Fn mRNA in the IR model group was significantly increased(P<0.05)while the expressions of GLP-1 and PYY mRNA were significantly decreased(P<0.05).Compared with the normal control group,the expression of Fn protein in the IR model group was significantly decreased(P<0.05)while the expressions of GLP-1 and PYY protein were significantly increased(P<0.05).ELISA results showed that compared with the normal control group,the secretion levels of Lyz in the IR model group were signifi-cantly decreased(P<0.01).② RT-qPCR results showed that compared with the normal control group,the expression of Lyz mRNA in the IR model group was significantly decreased(P<0.01).Compared with the IR model group,the expression of Lyz mRNA in the IR model+FM 50 and 100 μmol·L-1 groups was significantly increased(P<0.05,P<0.01).Western blotting results showed that compared with the normal control group,the expression of Lyz protein in the IR model group was significantly decreased(P<0.01).Compared with the IR model group,the expression of Lyz protein in the IR model+FM 50 and 100 μmol·L-1 groups was significantly increased(P<0.05,P<0.01).CONCLUSION The constructed IR mouse small intestinal organoid model provides a more complete in vitro research model for exploring the pathophysiological mechanism by which drug interventions help repair the intestinal mucosal barrier.FM may maintain the intestinal mucosal barrier by reversing the decrease in Lyz expression levels in IR mice,thereby improving IR.

Objective To determine the radiation dose of sensitive organs under different protective methods in lung CT scanning environment, and to explore the best protective scheme of corresponding organs. Methods Annealed thermoluminescence dose elements were placed in the stomach, liver, colon, and thyroid gland of a simulated human body model. The dose effect experiment of protective methods included non-protective group, half lead apron group, and full lead apron group. The dose effect experiment of protective thickness included 0.50 mmpb full lead apron group and 0.35 mmpb full lead apron group. The same exposure conditions of lung CT scan were used in the above experiments. Results Compared with the non-protective group, the exposure dose of the stomach, liver, colon, and thyroid gland increased significantly in the half lead apron group (P < 0.05), and the exposure dose of the thyroid gland and colon decreased significantly in the full lead apron group (P < 0.05). There were no significant differences in the exposure dose of the liver, stomach, and colon in the simulated human body model between the 0.35 mmpb full lead apron group and the 0.50 mmpb full lead apron group. Conclusion For lung CT scan, the protective measure of lead apron may not reduce the exposure dose of subjects. The protective thickness of lead apron does not necessarily have a substantial influence on the exposure dose of human body.

Objective    To analyze risk factors for chronic cough after minimally invasive resection of non-small cell lung cancer (NSCLC) and explore the possible prevention measures. Methods    A total of 128 NSCLC patients who received minimally invasive resection in 2018 in our hospital were enrolled, including 63 males and 65 females with an average age of 60.82±9.89 years. The patients were allocated into two groups: a robot-assisted thoracic surgery (RATS) group (56 patients) and a video-assisted thoracic surgery (VATS) group (72 patients). Chronic cough was assessed by visual analogue scale (VAS), meanwhile, other perioperative indicators were compared between the two groups. Univariate and multivariate logistic regression analyses were performed to identify risk factors for postoperative chronic cough and explore the prevention strategies. Results    Overall, 61 (47.7%) patients were diagnosed with chronic cough after surgery, including 25 (44.6%) patients in the RATS group and 36 (50.0%) patients in the VATS group, and the difference was not statistically significant (P>0.05). Compared with the VATS group, the RATS group got shorter endotracheal intubation time (P=0.009) and less blood loss (P<0.001). The univariate analysis showed that age (P=0.014), range of surgery (P=0.021), number of dissected lymph nodes (P=0.015), preoperative cough (P=0.006), endotracheal intubation time (P=0.004) were the influencing factors for postoperative chronic cough. The multivariate analysis showed that age <57 years (OR=3.006, 95%CI 1.294-6.986, P=0.011), preoperative cough (OR=3.944, 95%CI 4.548-10.048, P=0.004), endotracheal intubation time ≥172 min (OR=2.316, 95%CI 1.027-5.219, P=0.043), lobectomy (OR=2.651, 95%CI 1.052-6.681, P=0.039) were the independent risk factors for chronic cough. Conclusion    There is no statistical difference in postoperative chronic cough between the RATS and VATS groups. The RATS group gets less blood loss and shorter endotracheal intubation time. Patients with younger age (<57 years), preoperative cough, lobectomy, and longer duration of endotracheal intubation (≥172 min) are more likely to have chronic cough after surgery.
