【Objective】 To investigate the knowledge acquisition status for blood transfusion of transfusion related medical staff in underdeveloped cities in western China and explore its influencing factors. 【Methods】 A questionnaire consisted of blood transfusion laws and regulations, clinical blood transfusion theory and blood transfusion technology was designed, randomly distributed to medical staff and blood transfusion departmenttechnicians of 17 secondary/tertiary hospitals in Wuwei and then collected on the spot. The knowledge acquisition of blood transfusion of each group was compared using statistical description method, and its influencing factors were analyzed by multivariate logistic regression analysis. 【Results】 A total of 507 questionnaires were issued, and 498 valid questionnaires (98.22%) were collected. The scores of transfusion related laws and regulations, blood transfusion theory and blood transfusion technology of doctor group(n=158), nurse group(n=239) and transfusion technician group(n=101)were 4.56-5.97(5.06±0.73)(P<0.01) vs 4.23-5.87(4.98±1.24)(P<0.01) vs 3.71-0.78 (4.15±1.34), 3.67-5.02(4.27±1.02) vs 3.76-5.12(4.06±0.75) vs 4.71-5.98(5.16±0.64)(P<0.01) and 3.41-5.76(3.82±0.56) vs 3.78-5.24(4.01±0.56) vs 3.77-5.46(3.82±0.59). Among the seven departments, blood transfusion department(n=51) won the highest score of above three types of knowledge [4.91-5.97(5.28±0.43) vs 5.03-5.92(5.36±0.59) vs 4.39-5.77(4.97±0.79)(P<0.01) ]. Univariate logistic regression analysis showed that age, occupation, professional titles, training times and hospital grade had an impact on the degree (score) of blood transfusion knowledge acquisition (P<0.05), and multivariate unconditional logistic regression analysis indicated that training times was an important influencing factor(P<0.01). 【Conclusion】 This survey revealed that the level of knowledge acquisition for blood transfusion among medical staff in Wuwei is generally low, and there is a significant difference between staff from hospitals of different grade and different departments. It is urgent to strengthen the training of blood transfusion for medical staff in western China.

Objective To evaluate the safety and clinical efficacy of high intensity focused ultrasound (HIFU) for patients with solid tumors under sedation and analgesia. Methods Sedation and analgesia were induced with i.v. fentanyl(1?g/kg) and midazolam (0.03mg/kg) in 81 patients with benign or malignant solid tumors. High intensity focused ultrasound (HIFU) ablation treatment was then performed. The short-term effect and adverse events of sedatives and analgesics, as well as the effect of HIFU ablation treatment were observed. Results One hundred and twelve HIFU courses were performed on 81 patients, among them 23 patients with benign solid tumors received 26 courses of treatment, and 58 patients with malignant solid tumors, received 86 courses of treatment. A total of 153 foci were targeted. It was estimated that in 81% of all the patients, the tumor size was decreased by 50%, including 72.2%(52/72)of malignant tumors and 97.4%(37/38)of benign tumors. Tumor markers of malignant tumors decreased by more than 50% in 81.3%(13/16) of patients, and remission rate of tumor-related symptoms reached 77.9% (30/39). The adverse events during sedation and analgesia were nausea, reduction in the respiratory rate, visual hallucination, and that of HIFU were pain and swelling. No comblications with severity surpassing grade Ⅲ were found as a result of either sedatives, analgesics or HIFU treatment. Conclusion Sedation and analgesia are relatively safe, effective and feasible during HIFU treatment for solid tumor.

OBJECTIVE:
To compare the clinical efficacy of distal radius T-plate combined with suture anchor and distal clavicle anatomical locking plate combined with suture anchor in the treatment of Neer Ⅱb distal clavicle fracture.
METHODS:
From June 2014 to June 2018, 42 patients with Neer Ⅱb distal clavicle fractures were retrospectively analyzed. According to different surgical methods, they were divided into the observation group (T-shaped plate combined with suture anchor) and the control group (anatomical locking plate combined with suture anchor). There were 22 patients in the observation group and 20 patients in the control group. In the observation group, there were 13 males and 9 females, aged from 22 to 70 (45.78± 14.44) years old, 12 cases on the left side and 10 cases on the right side, 8 cases of traffic accident injury and 14 cases of fall. In the control group, there were 12 males and 8 females, aged from 24 to 66 (44.17±15.58) years, 13 cases on the left side and 7 cases on the right side, 6 cases of traffic accident injuryand 14 cases of fall. The operation time, intraoperative blood loss and fracture healing time were compared between the two groups, and Constant Murley score was used to evaluate shoulder joint function.
RESULTS:
The patients in both groups were followed up for 18 to 24 (20.96±2.02) months. The incisions of both groups were healed at stageⅠ. The fracture ends of both groups were bony healed at the last follow up. There was no significant difference in operation time, intraoperative blood loss and fracture healing time between two groups (
CONCLUSION
The two methods can obtain satisfactory results in the treatment of Neer Ⅱb distal clavicle fractures, especially suitable for patients with comminuted distal clavicle fractures or osteoporosis; the clinical effect of the treatment of NeerⅡb distal clavicle fractures with T type distal radius plate combined with suture anchor is satisfactory, which provides another feasible treatment scheme for clinic.

OBJECTIVE:
To detect the level of vascular endothelial growth factor (VEGF) in bone marrow of patients with non-M3 acute leukemia (AL), and estimate its relationship with prognosis.
METHODS:
From January 2016 to December 2019, 114 patients with AL in department of Hematology, Wuwei People's Hospital were selected as study group, and 25 healthy volunteers were enrolled as control group. The concentration of VEGF in bone marrow was detected by ELISA. The patients were divided into high and low concentration group according to the level of VEGF. The overall survival (OS) and event-free survival (EFS) were compared among different groups.
RESULTS:
The level of VEGF in patients with AL was significantly higher than that in the control group. The median OS and EFS in the low concentration group was 34.5 and 32 months, respectively, while, in the high concentration group was 30 and 26 months, respectively. The differences between the two groups were statistically significant (P=0.010). There were significant differences in OS rate (P=0.035) and EFS rate (P=0.026) between low and high concentration group. Multivariate analysis showed that high VEGF concentration was an independent risk factor affecting OS (HR=2.619, 95%CI 1.070-6.406, P=0.035) and EFS (HR=2.221, 95%CI 1.074-4.552, P=0.031) in AL patients.
CONCLUSION
VEGF highly expresses in the bone marrow of patients with AL at initial diagnosis and relapse, and shows adverse effects on the prognosis.

OBJECTIVE:
To investigate the clinical importance of combined detection of urinary amino acid metabolite --urinary tyrosine (UT) and tumor specific growth factor (TSGF) in the disease observation and curative effect evaluation of acute leukemia(AL).
METHODS:
In 87 cases of AL, the UT and TSGF levels were detected by using chemical chromogenic method and continuous monitoring method respectively. The 2 indicators of each treatment group were statistically analyzed and compared with that of 50 healthy control group.
RESULTS:
In 87 AL patients, the levels of UT and TSGF after treatment were significantly lower than those before treatment (P<0.01). The level of UT in non-remission(NR) group and partial remission(PR) group was significantly higher than that in completely remission(CR) group(P<0.01,P<0.05) and control group (P<0.01, P<0.01), The UT level in NR group was significantly higher than that in PR group (P<0.05), the UT level in CR group was significantly higher than that in control group (P<0.05). The levels of TSGF in NR and PR groups were significantly higher than those in CR and control groups(P<0.01, P<0.01). The level of TSGF in NR group was significantly higher than that in PR group(P<0.05), but no significant difference existed between CR group and control group(P>0.05).
CONCLUSION
UT and TSGF levels are related with the metabolism of tumor cells in AL patients. UT level can be used to predict the recurrence of patients with CR. The combined dynamical monitoring of these 2 indicators can be used as the indexes for observation of AL status, evaluation of therapeutic efficacy, prediction of prognosis and relapse of AL.

Population-based cancer registration data were collected to estimate the cancer incidence and mortality in Wuwei, Hexi Corridor Region, China in 2018. We used the 2011-2013 data to predict the number of new cases and deaths in 2018 and the 2003-2013 data to analyze trends in cancer incidence and mortality. The goal is to enable cancer prevention and control directions. Our results indicated that stomach cancer is the most common cancer. For all cancers combined, the incidence and mortality rates showed significantly increasing trends (+2.63% per year; P < 0.05 and +1.9% per year; P < 0.05). This study revealed a significant cancer burden among the population of this area. Cancer screening and prevention should be performed after an epidemiological study of the cause of the cancer is completed.

Objective To observe the effect of Simiaoyongan decoction with Shengmai decoction on apoptosis of hypoxia/reoxygenation model of primary cultured neonatal rat cardiomyocytes. Methods The combination of trypsin and collagenase was used to isolate neonatal rat myocardial cells. Hypoxia/reoxygenation model of cardiomyocytes was made by high purity nitrogen gas. Primary cultured neonatal rat cardiomyocytes were randomly divided into control group, model group and treatment group (treated with Simiaoyongan decoction and Shengmai decoction). The myocardial apoptotic rates were detected by Annexin V-FITC/PI double-staining method. Results Compared with the control group, the apoptotic rate of model group and treatment group was high (P<0.05). Drug intervention lowered the apoptotic rate compared with the model group, the difference was significant (P <0.05). Conclusion The alcohol sedimentation solution of Simiaoyongan decoction with Shengmai decoction played a protective role on hypoxia/reoxygenation cardiomyocytes.
