Since it has been found that autoimmune thyroid diseases (Graves' disease and moyamoya disease) may have a causal relationship mediated by immune mechanism, the relationship between thyroid autoantibodies and cerebrovascular diseases has attracted more and more attention. Recent studies have shown that thyroid antibody abnormalities can affect the occurrence and development of vascular events. Therefore, this article reviews the relationship between thyroid autoantibodies and intracranial artery stenosis and the related mechanism.

Glucokinase (GK) is a new target for the treatment of type II diabetes mellitus (T2DM). In order to find a structure-simplified small molecule GK activator, 19 salicylic acid derivatives were designed and synthesized based on new lead compound (1). Experimental results showed that the potency of compound 8h is superior to control RO-28-0450 in GK activation.

OBJECTIVE: To study the characteristics of adverse drug reactions( ADR) in our hospital. METHODS: 240 ADR cases collected between 2003 and 2006 in our hospital were analyzed retrospectively. RESULTS: Of the total ADR cases, 211( 87. 92% ) were induced by intravenous drugs, 153( 63. 75% ) were induced by antibacterials, and 118( 49. 17% ) were manifested as lesions of skin and its appendages. CONCLUSIONS: Importance should be attached to the monitor and reporting of ADR so as to lessen or avoid the occurrence of ADR.

A novel series of sorafenib analogs containing 2-picolinyl hydrazide moiety were designed and synthesized. In vitro, most of synthesized compounds have antiproliferation activity on MDA-MB-231, ACHN, HepG2, Mia-PaCa-2 and SW1990 cell lines tested by MTT assay. It is worth noting that the antitumor activities of compounds 2c, 2d and 2f are more potent than that of sorafenib on pancreatic cancer cells Mia-PaCa-2 and SW1990, and the activities of compounds 3f and 3g are 2-3 times than that of sorafenib on human hepatocellular carcinoma HepG2 cell line.

Objective To understand the incidence and mortality of malignancies as well as tumor burden of Shouyang County, Shanxi Province in 2012. Methods According to the review methods and the standards from the National Cancer Registry, the data of the incidence and mortality of malignant tumors in Shouyang County in 2012 were collected, collated and statistically analyzed. Results There were 389 new malignancies cases of Shouyang County in 2012, including 210 males and 179 females. The incidence rate was 187.61/100000 (190.00/100000 in males and 184.88/100000 in females). There were 263 death cases , including 164 males and 99 females. The mortality rate was 126.84/100000 (148.38/100000 in males and 102.25/100000 in females). The top 10 incidence of malignancies of the whole county was followed by lung cancer, cervical cancer, gastric cancer, liver cancer, colorectal anal cancer, esophageal cancer, breast cancer, bladder cancer, gallbladder cancer and uterus cancer, accounting for 86.12 ％ of the overall malignant cancers. The top 10 death malignancies of the whole county was followed by lung cancer, liver cancer, gastric cancer, esophageal cancer, Hodgkin disease, leukemia, colorectal cancer, bone cancer, brain tumor and pancreatic cancer, accounting for 87.45 ％ of the overall malignant cancers. Conclusion Lung cancer ranks first in the incidence and mortality of malignant tumors of Shouyang County, Shanxi Province, and the prevention and control of major tumors should be strengthened.

Objective:To investigate the effect of vector sum concept in fine-tuning posterior column screw channel via ilioinguinal approach for the treatment of bi-column acetabular fracture.Methods:A retrospective cohort study was conducted to analyze the clinical data of 42 patients with acetabular double column fracture admitted to Weifang People′s Hospital from July 2015 to May 2021, including 22 males and 20 females, aged 23-77 years [(49.3±16.3)years]. The ilioinguinal approach was used in all patients with the anterior column fixed with a plate and posterior column fixed with a lag screw. The vector sum concept was used intraoperatively to fine-tune the posterior column screw channel in 19 patients (channel fine-tuning group): namely, a 2.5 mm Kirschner wire was inserted into the bony channel of the posterior column screw under fluoroscopy of iliac oblique and obturator oblique positions; when the Kirschner wire was not located in the middle of the ischial ramus under single fluoroscopy, the vector only needed to be adjusted in one direction, with zero in the other direction; when the Kirschner wire was not located in the middle of the ischial ramus under fluoroscopy of both the iliac oblique and obturator obturator oblique positions, the sum of the deviation vectors in the two directions was calculated before fine-tuning. The vector sum concept was not used to fine-tune the posterior column channel screw in 23 patients (channel non-fine-tuning group). The time of posterior column screw placement, intraoperative blood loss, frequency of guide wire adjustment and fracture healing time were recorded and compared between the two groups. At 6 months after operation, the quality of fracture reduction and hip function were assessed by Matta score and Merle D′Aubigne-Postel score, respectively. The complications were observed.Results:All patients were followed up for 7-71 months [(35.7±8.5)months]. In channel fine-tuning group, the time of posterior column screw placement was (5.1±1.5)minutes, with intraoperative blood loss of (798.8±83.9)ml, frequency of guide wire adjustment of (1.8±0.5)times and fracture healing time of (12.4±3.2)weeks; while these parameters [(39.8±12.0)minutes, (1 119.3±172.0)ml, (5.6±1.6)times and (15.6±4.2)weeks] were significantly shorter or less in channel non-fine-tuning group ( P<0.05 or 0.01). There were no significant difference in the quality of fracture reduction and hip function between the two groups at 6 months postoperatively (all P>0.05). After operation, symptoms of lateral femoral cutaneous nerve was found in seven patients, superficial incision infection in two who was healed after debridement and dressing change, deep venous thrombosis of lower limbs in three. There was no significant difference in the incidence of postoperative complications between the two groups [channel fine-tuning group: 26%(5/19), channel non-fine-tuning group: 30%(7/23)] ( P>0.05). Conclusion:For bi-column acetabular fractures via ilioinguinal approach, application of vector and concept to fine-tune the posterior column screw channel is beneficial for rapid screw placement into the osseous channel, significant reduction of intraoperative blood loss and early fracture healing.

Objective To explore the risk factors for lower limb venous thrombosis in patients after craniocerebral surgery,and establish a prognostic nomogram for the occurrence of lower limb venous thrombosis.Methods A total of 427 patients who underwent craniotomy for craniocerebral trauma and met the inclusion criteria in the First People's Hospital of Taicang from January 2018 to December 2020 were collected as training group,and the nomogram was drawn and verified internally.And 106 patients who underwent surgery from January 2021 to June 2021 were used as test group,and the model was externally verified set.The nomogram was established and internally validated with the data of the training group,and externally validated with the data of the test group.For the training group,multivariate Logistic regression analysis was performed by including all variables with P＜0.05 in univariate analysis,and established the prognostic nomogram by R software.In the training group and the test group,the performance of the nomogram was verified by C-index,calibration chart and decision curve analysis respectively.Results In the training group of 427 people,107 had lower limb venous thrombosis,with an incidence rate of 25.1％.Among the 106 people in the test group,33 developed lower limb venous thrombosis,with an incidence rate of 31.1％.Multivariate logistic regression analysis showed that age,lower preoperative GCS score,postoperative lower limb muscle strength＜3,hypertension,and diabetes were independent risk factors for the occurrence of lower limb vein thrombosis after craniocerebral surgery.The C-index of this nomogram in the training group and the test group was 0.837(95％CI:0.796-0.878)and 0.933(95％CI:0.886-0.979),respectively.Conclusion The nomogram including the age,preoperative GCS score,postoperative lower limb muscle strength＜3,hypertension,and diabetes can predict the probability of lower limb vein thrombosis after craniocerebral surgery with convenient discrimination and clinical utility.

Oocyte cryopreservation is widely used for clinical and social reasons. Previous studies have demonstrated that conventional slow-freezing cryopreservation procedures, but not storage time, can alter the gene expression profiles of frozen oocytes. Whether vitrification procedures and the related frozen storage durations have any effects on the transcriptomes of human metaphase II oocytes remain unknown. Four women (30-32 years old) who had undergone IVF treatment were recruited for this study. RNA-Seq profiles of 3 fresh oocytes and 13 surviving vitrified-thawed oocytes (3, 3, 4, and 3 oocytes were cryostored for 1,2, 3, and 12 months) were analyzed at a single-cell resolution. A total of 1987 genes were differentially expressed in the 13 vitrified-thawed oocytes. However, no differentially expressed genes were found between any two groups among the 1-, 2-, 3-, and 12-month storage groups. Further analysis revealed that the aberrant genes in the vitrified oocytes were closely related to oogenesis and development. Our findings indicated that the effects of vitrification on the transcriptomes of mature human oocytes are induced by the procedure itself, suggesting that long-term cryostorage of human oocytes is safe.

Objective: To investigate the etiology, clinical and pathological characteristics of laryngeal leukoplakia and the predictive risk factors of recurrence and malignant transformation. Methods: Clinical data of 263 patients with laryngeal leukoplakia between January 2000 and December 2015 were analyzed retrospectively. Results: The pathological diagnoses included squamous epithelial hyperplasia (54.4%), mild dysplasia (17.9%), moderate dysplasia (12.2%), severe dysplasia and carcinoma in situ (12.5%), and invasive carcinoma (3.0%). Age and the extent of lesion were statistically different among different pathological groups (P<0.05). Gender, smoking and alcohol consumption did not show statistical differences among different pathological groups (P>0.05). Follow-up of 215 patients, excluding 6 cases of invasive carcinoma. The recurrence rate was 20.6%(43/209), and the malignant transformation rate was 5.3%(11/209). Multivariate analysis showed that pathological classification of moderate to severe dysplasia was the independent risk factor for recurrence and malignant transformation of laryngeal leukoplakia (P<0.05). In patients with severe dysplasia and carcinoma in situ, the recurrence proportion of conservative treatment, vocal cords (partial) resection and radiotherapy were 8/10, 0/10 and 2/11 respectively. Conclusions Laryngeal leukoplakia occurs frequently in elderly men with long-term smoking history. Pathological diagnoses are different. The grade of dysplasia is the predictive risk factor for the recurrence and malignant transformation of laryngeal leukoplakia. More aggressive treatment and closer follow-up should be warranted for patients with moderate dysplasia, severe dysplasia and carcinoma in situ.
