OBJECTIVES: To establish an automation system for detection of alcohol content in blood. METHODS: The determination was performed by automated workstation of extraction-headspace gas chromatography （HS-GC）. The blood collection with negative pressure, sealing time of headspace bottle and sample needle were checked and optimized in the abstraction of automation system. The automatic sampling was compared with the manual sampling. RESULTS: The quantitative data obtained by the automated workstation of extraction-HS-GC for alcohol was stable. The relative differences of two parallel samples were less than 5%. The automated extraction was superior to the manual extraction. A good linear relationship was obtained at the alcohol concentration range of 0.1-3.0 mg/mL （r≥0.999） with good repeatability. CONCLUSIONS The method is simple and quick, with more standard experiment process and accurate experimental data. It eliminates the error from the experimenter and has good repeatability, which can be applied to the qualitative and quantitative detections of alcohol in blood.

Seventy two patients with initial cerebral infarction admitted in the Second Hospital of Jiaxing from March 2017 to October 2017 were enrolled. Patients underwent conventional ultrasonography and contrast-enhanced ultrasonography for two-dimensional echo grading and neovascularization grading of carotid artery plaques respectively. There were 113 carotid plaques in 72 patients with cerebral infarction,27 cases recurred after 1 years with 44 patches. The echo grading of recurrence group was mainly grade Ⅰ and grade Ⅱ,the number of Ⅰ,Ⅱ,and Ⅲ plaques was 23,18,and 3,respectively. The echo grading of non-recurrence group was mainly grade Ⅲ,the number of Ⅰ,Ⅱ,and Ⅲ plaques was 36,23,and 40,respectively. The echo grading of carotid artery plaque between the two groups was significantly different (P<0.05). The grade of carotid neovascularization in recurrence group was mainly grade Ⅲ and grade Ⅳ,the number of Ⅰ,Ⅱ,Ⅲ and Ⅳ plaques was 2,5,27 and 10,respectively. The echo grading of non-recurrence group was mainly grade Ⅰ and grade Ⅱ,the number of Ⅰ,Ⅱ,Ⅲ and Ⅳ plaques was 24,52,14 and 9,respectively. There was significant difference in the grade of carotid neovascularization between the two groups (P<0.05). The area under curve(AUC) of echo grade<Ⅱ,echo grade<Ⅲ,neovascularization grade>Ⅰ,neovascularization grade>Ⅱ and neovascularization grade>Ⅲ in predicting the recurrence of cerebral infarction were 0.553,0.641,0.587,0.793 and 0.557,respectively,the AUC of neovascularization grade>Ⅱ was significantly higher than the other four criteria (P<0.01). The recurrence curves of carotid plaques with different neovascularization grades were significantly different (χ²=49.18,P<0.01). Carotid plaque vulnerability evaluated by contrast-enhanced ultrasonography is an effective indicator for predicting recurrence of cerebral infarction.

Objective: To explore the anesthetic effect of low dose remifentanil in patients undergoing sequential painless gastroscopy and painless colonoscopy in accordance with intravenous induction of propofol. Methods: From July 2017 to January 2018, 86 patients who needed painless gastroscopy and painless colonoscopy in sequence were selected as observation objects in the Second Hospital of Jiaxing and were divided into control group and observation group according to random number table method, with 43 cases in each group.The control group was anesthetized with propofol only, while the observation group was anesthetized with low dose remifentanil in accordance with propofol.The occurrence of adverse reactions and recovery were compared between the two groups. Results: The incidence rate of adverse reactions of the control group was 20.93%(9/43), which of the observation group was 13.95%(6/43), there was no statistically significant difference between the two groups (χ²=0.272, P=394). The recovery time and the observation time after awakening in the observation group were (7.19±1.98)min and (6.94±2.04)min, respectively, which were significantly shorter than those in the control group [(10.33±2.42)min and (11.69±3.21)min], the differences were statistically significant (t=6.585, 8.190, P=0.000, 0.000). Conclusion Intravenous induction with low dose remifentanil combined with propofol in patients undergoing painless gastroscopy and painless colonoscopy in sequence has less adverse reactions, good anesthesia persistence and short recovery time, which is worthy of clinical popularization.

It is extremely dangerous to treat the posterior third of the superior sagittal sinus (PTSSS) surgically, since it is usually not completely ligated. In this report, the authors described the case of a 27-year-old man with a ruptured and defective PTSSS caused by an open depressed skull fracture, which was treated by ligation of the PTSSS and the patient achieved a positive recovery. The patient's occiput was hit by a height-limiting rod and was in a mild coma. A CT scan showed an open depressed skull fracture overlying the PTSSS and a diffuse brain swelling. He underwent emergency surgery. When the skull fragments were removed, a 4 cm segment of the superior sagittal sinus (SSS) and the adjacent dura mater were removed together with bone fragments. Haemorrhage occurred and blood pressure dropped. We completed the operation by ligating the severed ends of the fractured sagittal sinus. One month after the operation, apart from visual field defects, he recovered well. In our opinion, in primary hospitals, when patients with severely injured PTSSS cannot sustain a long-time and complicated operation, e.g., the bypass using venous graft, and face life-threatening conditions, ligation of the PTSSS is another option, which may unexpectedly achieve good results.

PURPOSE: To explore the diagnosis and treatment of traumatic external carotid branch pseudoaneurysms. METHODS: Eleven cases of traumatic external carotid artery branch pseudoaneurysms were admitted in our hospital. Digital subtraction angiography was performed in all patients. It revealed that the pseudoaneurysms originated from the internal maxillary artery in 5 cases, superficial temporal artery in 5 cases and occipital artery in 1 case. Five cases of internal maxillary artery pseudoaneurysms and 2 cases of superficial temporal artery pseudoaneurysms were treated by embolization; the other 3 cases were surgically resected. RESULTS: Complete cessation of nasal bleeding was achieved in all the 5 pseudoaneurysms of internal maxillary artery after the endovascular therapies. Scalp bleeding stopped and scalp defect healed up in 2 patients with superficial temporal artery pseudoaneurysms treated by interventional therapy. All patients were followed up for 0.5-2.0 years without recurrence of nosebleed and scalp lump. CONCLUSION For patients with repeated severe epistaxis after craniocerebral injury, digital subtraction angiography should be performed as soon as possible to confirm traumatic pseudoaneurysm. Endovascular therapy is an effective method for traumatic internal maxillary artery pseudoaneurysms. For patients with scalp injuries and pulsatile lumps, further examinations including digital subtraction angiography should be performed to confirm the diagnosis. Surgical treatment or endovascular therapy for scalp traumatic pseudoaneurysm is effective.

Objective: To detect the expression of B cell transposition gene 3(BTG3) in pancreatic ductal adenocarcinoma(PDAC), and explore its relationship with postoperative recurrence and metastasis of tumor. Methods: Six self-paired frozen PDAC specimens and 3 normal pancreatic tissues from the Second Hospital of Jiaxing Affiliated to Jiaxing University were collected and the expression of BTG3 was detected by qPCR. Ten normal pancreatic tissues and 52 cases of PDAC tumor and paracarcinomatous tissues from the Second Hospital of Jiaxing Affiliated to Jiaxing University were collected from June 2009 to December 2016. The expression of BTG3 and relationship among BTG3 and clinicopathological characteristics of PDAC and patients′ prognosis were detected and analyzed using immunohistochemistry.χ² test, Kaplan-Meier method and Cox regression model were used to analyzed the data. Results: The results of qPCR showed that expression level of BTG3 in PDAC (0.63±0.17) was lower significantly than that in paracarcinomatous (0.96±0.04) and normal tissues (1.00)(t=4.673, 5.502; both P<0.05). Immunohistochemistrv showed that BTG3 mainly expressed in the cytoplasm.The high expression rate of BTG3 in PDAC tumor tissues was 25.0%(13/52), which was remarkably lower than that in paracarcinomatous tissues(65.4%) and normal liver tissues(7/10)(χ²=17.120 and 5.849, both P<0.05). The low expression of BTG3 in PDAC was correlated with primary tumor, and TNM stage(χ²=7.704, P=0.006; U=154.000, P=0.018, respectively). Survival analysis showed that disease free survival rate of patients with low expression of BTG3 was significantly less than that with high expression(χ²=192.493, P<0.01). The Cox multivariate analysis demonstrated that low expression of BTG3 was independent risk factors for disease free survival in patients with PDAC after a curative resection(RR=3.366, 95%CI: 1.040-10.889, P=0.043). Conclusion BTG3 may be involved in the occurence and development of tumor, and its low expression may be associated with poor prognosis in patients with PDAC.
