Objective To discuss action of microelement Se in serum and milk of gestational diabetes melli-tus parturient.Methods The serum and milk samples were collected from 50 gestational diabetes mellitus parturient and 50 healthy parturient.The selenium contents were detected by radioimmunoassay.Results The serum Se content in gestational diabetes mellitus parturient was obviously lower than that in healthy parturient(t =2.128,P <0.05). The milk Se content in gestational diabetes mellitus parturient was lower than that in healthy parturient(t =1.014, P >0.05).Conclusion Selenium deficiency persisted in gestational diabetes mellitus parturient.But Selenium defi-ciency did not exist in milk of gestational diabetes mellitus parturient.So encouraging breastfeeding,elevating selenium containing food intake,and supplement the selenium preparation properly maybe prevent and delay type 2 diabetes in gestational diabetes mellitus parturient.

It has been reported that the high expression of gastrins and their receptors promotes some colorectal neoplasms cells proliferation and inhibit apoptosis.MicroRNAs (miRNAs) are closely related to gene expression regulation in colorectal neoplasms.Researches show that miRNAs have multiple intersections in the regulatory network of colorectal neoplasms with the signal transduction pathway of gatrins which controls the proliferation of colorectal neoplasms.Gastrins perhaps control the proliferation of colorectal neoplasms cells through miRNA signal transduction pathways.These findings have greatly expanded the understanding of the pathoge nesis of colorectal neoplasms and will provide new ideas and methods for the diagnosis and treatment of colorectal neoplasms.

Objective To introduce the clinical apply of middle and small skin defect in finger injury with lateral arm free perforator flap.Methods (1) Ten cadavers were injected with a modified lead oxide-gelatin mixture.Later,CT scan,three-dimensional reconstruction of the cutaneous perforator vessels on the later arm.Then simulate the flap design.All cadavers were dissected before CT scanning.(2) Eighteen cases of middle and small skin defects in finger injury were treated with lateral arm free flap.The defect area were from 3 cm × 4 cm to 6 cm × 9 cm.Results Our research showed that the average caliber diameter of perforators of profunda brachial artery(PBA) was (0.71 ± 0.15) mm,and Posterior radial collateral artery(PRCA) was (0.94±0.22)mm.The results of pedicle length of perforator of PBA was (2.74 ±0.42) cm:(2.96 ±0.37) cm,and PRCA was (4.78 ±0.63) cm:(4.86 ±0.51) cm.3D reconstructive results showed that the perforators of PBA and PRCA dominated the lateral upper arm area.The flap of 18 cases survived after the operation.The wound of providing area was directly sutured or skin grafting and got healing.All cases were followed up for 6 months to 3 years,and the average follow-up time was 11 months.There was a little swelling on the outlooks of the flap,but the texture and sensation of the flap was good.Conclusion The lateral arm free perforator flap has a stable vessel pedicle,good texture and sensation,so it was a good method to repair middle and small skin defect in finger injury.

Objective To investigate the relationship between vessel cancer embolus with other clinicopathological features and tumor tissue KRAS gene mutation in the patients with colorectal cancer and its significance to colorectal cancer prognosis.Methods The postoperative clinicopathological data in 182 patients with colorectal cancer during 2011-2014 were retrospectively analyzed and the patients were followed up.Results Forty-five cases showed vessel cancer embolus positive of colorectal cancer,which had the rrelationship with the lymph node metastasis,pathological differentiation degree,liver metastasis,nerve infiltration and increase of CEA and CA199 levels,while had no relationship with the age,sex,tumor size,infiltration depth and pathological type.The 3-year survival rate was 51.1% in the vessel cancer embolus positive group,which was significantly lower than 61.3% in the negative group (P<0.05).However,the 3-year survival rate had no statistically significant difference between the vessel cancer embolus positive complicating KRAS gene mutation group and the vessel cancer embolus positive group(P>0.05).Conclusion Vessel cancer embolus decreases the 3-year survival rate and affects the prognosis in the patients with colorectal cancer.The survival rate in complicating KRAS gene mutation is similar.

Interventional medicine plays an important role in the diagnosis and treatment of cardiovascular and cerebrovascular diseases, hepatobiliary tumors and other diseases, which has become the third largest type of treatment technology besides internal and surgical treatment. In recent years, with technological breakthroughs in imaging technology, robotic surgical system, artificial intelligence, Internet of Things and other fields, unprecedented opportunities have been provided for interventional/minimally invasive+robotics. Interventional robotic surgical systems have mushroomed around this field. The authors discuss the current status and future of interventional robotic surgical system with high recognition worldwide, especially the three categories of specialized robotic surgical system for vascular intervention, percutaneous puncture intervention and natural non-vascular luminal intervention.

Objective To investigate the effects of surgery-induced menopause on neuropsychological symptoms in women with perimenopause. Methods Sixty-eight women with perimenopause who underwent bilateral oophorectomy for benign indications were evaluated by the modified Kupperman index on the perimenopause syndrome pre-and post-surgery,including the score in neuropsychological symptoms.Patients were further requested to remake a decision on the acceptance of surgery,and were divided into "accept the surgery" group(n=30) and "postpone the surgery" group(n=38).The neuropsychological symptoms were reevaluated and comparison was made between these two groups. Results The prevalence of perimenopause syndrome pre-surgery was 67.65%(22/68),and that of moderate and severe symptoms was 30.88%.The prevalence of perimenopause syndrome post-surery(97.06%)(66/68)was significantly increased,as well as that of moderate and severe symptoms(70.59%)(P

Objective:To investigate the effect of miRNA-5089-5p (miR-5089-5p) on proliferation and migration ability of esophageal cancer in vitro and its relationship with the expression of cathepsin B (CTSB) gene.Methods:Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression levels of miR-5089-5p in 31 tissue samples from patients who underwent esophageal cancer resection and the corresponding pericarcinomatous tissues between in March 2017 and in December 2019 at Huangshi Central Hospital of Edong Healthcare Group, and TE-13, EC9706, Eca109, KYSE30 cell lines and normal esophageal mucosal epithelial HET-1A cells. The esophageal cancer cells with the lowest expression level of miR-5089-5p were divided into 2 groups: miR-5089-5p group transfected with miR-5089-5p mimics and the negative control group with negative control sequence. qRT-PCR was used to detect the expression level of miR-5089-5p after transfection for 48 h. CCK-8 method and scratch healing test were used to detect the proliferation and migration ability of cells in the two groups. The online tools microRNA.org and Deepbase v2.0 were used to predict the target genes of miR-5089-5p. The dual luciferase reporter gene assay was used to verify the target gene of miR-5089-5p. qRT-PCR and Western blot were used to detect the expression level of target genes in the two groups. The expressions of cell proliferation-related protein (PCNA and Ki-67) and migration-related protein (N-Cadherin and Twist) were detected by using Western blot.Results:The relative expression level of miR-5089-5p in esophageal cancer and pericarcinomatous tissues was 1.54±0.53 and 7.07±1.25, respectively ( t = 24.06, P < 0.01). The relative expression level of miR-5089-5p in the esophageal cancer cell lines was lower than that of normal esophageal mucosal epithelial HET-1A cells (all P < 0.05), and the cell line with the lowest relative expression was Eca109 cells (0.12±0.03). Compared with the negative control group, the proliferation ability of Eca109 cells in miR-5089-5p group was gradually reduced with the transfection time extension, and the difference was statistically significant between the two groups since 48 h (all P < 0.05), and the migration ability was also reduced [scratch healing rate: (29±5)% vs.(64±8)%, t=3.91, P < 0.01]. The online tool predicted that the target gene of miR-5089-5p might be CTSB, and the dual luciferase reporter gene assay confirmed that miR-5089-5p complemented CTSB 3'UTR. qRT-PCR results showed that compared with the negative control group, the relative expression level of CTSB mRNA in Eca109 cells of miR-5089-5p group was reduced (0.23±0.04 vs.1.01±0.09, t = 8.27, P < 0.01). Western blot results showed that the expression level of CTSB protein was reduced, and the expression levels of cell proliferation-related protein PCNA, Ki-67 and cell migration-related protein N-Cadherin, Twist were also reduced. Conclusions:The expression level of miR-5089-5p in esophageal cancer tissues and cell lines is low. miR-5089-5p can inhibit proliferation and migration of esophageal cancer Eca109 cells. The mechanism may be achieved by down-regulating CTSB gene expression.

Objective To investigate the diagnosis and surgical treatment of pancreatic cystic tumor.Methods The clinical data of 19 cases of pancreatic cystic tumor from January 2000 to August 2009 was retrospectively analyzed. Results Patients with pancreatic cystic tumor has no specific clinical feature.Ultrasound and CT were main image examinations, but they could not distinguish the pathologic types, and the diagnostic accuracy when compared with postoperative pathologic results was 57.9% (11/19) and 68.4%(13/19) respectively. The tumors were located in the pancreatic head and neck in 5 cases, body and tail in 14 cases, the maxim diameter was between 3 ～ 15 cm. All patients underwent surgical treatment; the rate of curative resection was 84. 2% ( 16/19 ). The rate of intraoperative misdiagnosis was 21.0% ( 4/19 ).Pathologic examination results showed 6 cases of serous cystadenoma, 6 cases of mucinous cystadenoma, 5 cases of mucinous cystadenocarcinoma, and 2 cases of intraductal papillary mucinous adenoma. 15 ( 78.9% )patients were followed up. Among the 3 patients with mucinous cystadenocarcinoma, one patient who received curative resection survived for 4 years with no evidence of recurrence; the other 2 patients died 4 months and 7 months later. 12 cases of cystadenoma were alive without recurrence. Four patients, including 2 patients of cystadenoma and 2 patients of cystadenocarcinoma were lost in follow-up. Conclusions To be aware of pancreatic cystic tumors is the key to reduce misdiagnosis and mistreatment. Surgical treatment is the treatment of choice with excellent prognosis.
