Large vascular lesions have become one of the main causes in the death and disability of type 2 diabetes mellitus (T2DM). The article systematically and in-depthly studied the mechanism of large vascular lesions in T2DM, in order to seek effective drug prevention and treatment. It was of vital importance in the improvement of prognosis of T2DM patients. In traditional Chinese medicine (TCM), the basic pathogenesis of T2DM large vascular lesions was deficiency in origin and excess in superficiality, in whichqi-yin deficiency was the origin and the obstruction of collaterals was the superficiality. In western medicine, the body endothelial dysfunction, oxidative stress reaction and abnormal gene expression and so on could cause T2DM large vascular lesions. This article summarized related research literatures on both TCM and western medicine in recent years. It discussed studies on mechanism of T2DM large vascular lesions.

Objective: To assess the clinical features, diagnosis and treatment of gastrointestinal stromal tumor in the rectum.Methods: Records of 18 patients diagnosed as GIST in the rectum between January 2002 and April 2009 were re-viewed and the major clinical features, treatment modalities and outcomes were analyzed.Results: The clinical features of GIST in the rectum were nonspecific.Most patients manifested with bloody stool or changes in bowel habits.CT scan or MRI findings showed necrosis and/or hemorrhage in the tumor and well defined tumor margins.Even in the case of large GIST, no lymphadenopathy was not found, which could be a factor for the differential diagnosis of GIST from other rectal neoplasms.All of the resected tumor specimens showed positive expression of CD117 and CD34 in immunohistochemical staining.Low and very low risk patients accounted for 44.4% (8/18).All patients received surgery.Twelve patients were treated with local excision with different approaches.Anterior resection of the rectum (Dixon) was undertaken in three pa-tients and abdominoperineal resection (Miles) in three patients.Neoadjuvant therapy with imatinib was applied for three pa-tients with partial response.After a median follow-up of 34 months (1～84 months), recurrence and/or metastasis occurred in five patients, and three of them were treated with imatinib.One patient received Miles surgery after repeated local exci-sions.Only one patient died of bone metastasis.Recurrence-free survival (RFS) of the local excision group was longer than that of abdominoperineal resection (APR) group (75.0±8.4 months vs 26.0±11.1 months, P=0.023).Conclusion: The treatment for rectal GIST should be individualized and be different from that of rectal cancer.Treatment decision and choice of procedures should be based on careful preoperative evaluation of tumor size, location, extent and risk level.Most of the anorectal GIST were rated as low-risk in this cohort and could be excised locally by different approaches with satisfactory outcome.Neoadjuvant therapy with imatinib may benefit some patients to obtain the opportunity of sphincter-saving.

Multiple myeloma is common in the older population and is treated mainly with chemotherapy. However, chemotherapy-related side effects imitate the clinical manifestations of Sheehan's syndrome, which leads to misdiagnosis and missed diagnosis, particularly for older patients without a clear history of postpartum hemorrhage. Therefore, when older women with malignant myelomas show refractory hyponatremia and gastrointestinal disorders while under chemotherapy, a diagnosis of Sheehan's syndrome should be considered. The early detection of the disorder will guarantee timely individualized treatment.

OBJECTIVE: To explore the clinicopathologic and molecular characteristics of hereditary nonpolyposis colorectal cancer (HNPCC), and to improve the level of diagnosis and treatments of HNPCC. METHODS: Thirty HNPCC patients (HNPCC group) who were treated in Xiangya Hospital were retrospectively analyzed, and 25 patients with sporadic colorectal cancer in the same duration were randomly chosen as a control group. The onset of age, location of tumor, pathological type, treatment method, and prognosis were compared in the 2 groups. The expression loss rate of mismatch repair gene (MMR) MLH1 and MSH2 in the 2 groups was detected by immunohistochemistry. RESULTS: The onset age in the HNPCC group was earlier than that in the control group (P<0.05). The rate of proximal colonic tumor the occurrence of multiple tumors, and the proportion of well differentiated adenocarcinoma in the HNPCC group were all higher than those in the control group (P<0.05). The expression loss rate of MLH1 and MSH2 in the HNPCC group was higher than that in the control group (P<0.05). One third in the HNPCC group received subtotal proctocolectomy. The prognosis of HNPCC patients was comparable with that of patients with sporadic colorectal cancer (P>0.05). CONCLUSION HNPCC patients are characterized with early onset associating with multiple tumors. The accuracy of diagnosis can be improved by combining the detection of MMR gene. Optimal surgical treatment and close follow-up may bring good result to HNPCC patients.

OBJECTIVE: To assess the value of proximal gastrectomy (PG) and total gastrectomy (TG) for the treatment of cancer of cardia and fundus. METHODS: Publications on comparision between PG and TG in the treatment of cancer of cardia and fundus were collected, the data from the publications were matched with the PG group and the TG group respectively according to its corresponding surgical resection, and the data on postoperative complications, motality and 5-year survival rate were meta-analyzed by fixed effect model and random effect model. RESULTS: Thirteen reseaches on 2 219 patients were included in this study, 2 of which were randomly controlled studies. There were no significant differences in the postoperative complications (OR=1.00, 95%CI: 0.44-2.28,P>0.05) and mortality (OR=1.25, 95%CI: 0.62-2.48,P>0.05) between the PG group and the TG group, while there was significant difference in the 5-year survival rate (HR=0.87, 95%CI: 0.76-0.99,P=0.04). The 5-year survival rate in the TG group was higher than that in the PG group. CONCLUSION Total gastrectomy for the treatment of cancer of cardia and fundus has better long-term therapetic effect.

Objective:To investigate the clinical effect of modified atlantooccipital decompression combined with occipitocervical internal fixation on Chiari type I malformation combined with syringomyelia and atlantoaxial dislocation.Methods:Twenty-five patients with Chiari I malformation combined with syringomyelia and atlantoaxial dislocation accepted by modified atlantooccipital decompression combined with occipitocervical internal fixation in our hospital from January 2011 to March 2019. The clinical data of these patients were retrospectively analyzed. The changes of peak velocity of cerebrospinal fluid in the dorsal part of the spinal cord, electrophysiological results, atlantodental interval (ADI) values, sizes of syringomyelia, and Chicago Chiari outcome scale (CCOS) scores before and after operation were compared.Results:The peak velocity of cerebrospinal fluid in the dorsal spinal cord after surgery ([3.25±0.47] cm/s) was statistically higher in these patients than that before surgery ([2.13±0.19] cm/s, P<0.05). As compared with the preoperative results, ADI values, sizes of syringomyelia, and proportion of patients with abnormal electrophysiological monitoring at 6 months after surgery were significantly decreased, and CCOS scores at 6 months after surgery were significantly increased ( P<0.05). There were no new nerve function damage, infection, cerebrospinal fluid leakage, paralysis, respiratory failure or death. Conclusions:Modified atlantooccipital decompression combined with occipitocervical internal fixation plays effective role in atlantooccipital decompression and atlantoaxial anatomical reduction in patients with Chiari malformation type I combined with syringomyelia and atlantoaxial dislocation. The remission rate of syringomyelia is high, the symptoms and signs improve obviously, and the postoperative complications are less.

Objective This study was conducted to analyze the clinical characteristics and pituitary function of patients with primary empty sella (PES).Methods The clinical data from 123 hospitalized adult patients with PES from January 2010 to May 2016 were retrospectively studied.Results (1) The average age of the 123 (male 43,female 80) PES patients was (59.2 ± 13.6) years (ranging 24-92 years),among whom 61％ patients were in the age group between 50-69 years.(2) The symptoms of the patients included fatigue (56.1％),headache (34.1％),nausea and vomiting (17.9％),gonadal dysfunction (17.1％),visual disturbance (5.7％) and hypopituitarism crisis (3.3％).(3) Hypopituitarism was found in 66 of the 123 patients.Among them,36.6％,31.7％ and 17.1％ were central hypoadrenalism,hypogonadism,and hypothyroidism,respectively.The percentage of hypopituitarism in complete PES was significantly higher than that in partial PES (P ＜ 0.05).(4) Sixteen patients were concomitant with other autoimmune diseases including 11 patients with Graves' disease and 2 with Cushing's syndrome due to adrenal adenoma.Conclusions The incidence of hypopituitarism in PES was 53.7％,in which the pituitary-adrenal axis hypofunction was more common.An overall evaluation of the pituitary function was essential for the patients who had headache and fatigue,or with suspected PES.The patients with hypopituitarism should be given hormone replacement therapy in time and followed up afterword.
