CMV related matrix protein pp65 antigenemia was screened in 100 Allo HSCT patients after transplantation. As control groups, samples from fourteen autologous HSCT patients, seventeen patients with various hematological malignant disorders, as well as twenty seven normal donors also were detected. CMV antigenemia was found in 91/100 Allo HSCT patients (91%) after transplantation. 56 % patients with antigenemia developed CMV disease. 54% patients developed acute GVHD. In 87 patients survived more than three months, 52 9% patients developed chronic GVHD. After follow up 18(4～36) months post transplantation, 21 patients died of CMV related diseases. Compared with autologous and non transplantation patients, CMV antigenemia and CMV diseases were particularly associated with Allo HSCT patients. It was obviously correlated with acute and chronic GVHD. CMV infection is a major factor affecting the clinical outcome of Allo HSCT patients.

Objective: To compare the clinical efficacy of minimally invasive closed reduction and open reduction and internal fixation in the treatment of ankle fractures. Methods: 133 cases with ankle fractures were selected.They were divided into closed group (65 cases) and incision group (68 cases) according to random table method.The closed group was treated with minimally invasive closed reduction, and the incision group was treated with open reduction and internal fixation.The therapeutic effect, amount of bleeding, time of fracture healing, time of operation and postoperative complications were compared between the two groups. Results: The good rate of the closed group (98.46%) was higher than that of the control group(85.29%, χ²=7.594, P<0.05). The amount of bleeding in the closed group[(19.40±3.56) mL] was less than that in the incision group[(39.84±4.15)mL], the fracture healing time in the closed group[(10.24±2.15)weeks] was shorter than that in the incision group[(15.46±3.67)weeks], the operation time in the closed group[(38.94±8.71)min] was shorter than that the incision group[(59.38±13.25)min](t=30.424, 9.950, 10.462, all P<0.05). The incidence rate of postoperative complication in the closed group (1.54%) was lower than that in the incision group (16.18%, χ²=8.675, P<0.05). Conclusion Minimally invasive closed reduction in the treatment of ankle fractures is better than open reduction and internal fixation, and has important research value.

The experience of various countries proves that the hierarchical diagnosis and treatment model can lead to reasonable resources allocation and utilization, however, the waste of China''s disordered treatment model has not been estimated.Nowadays, it is very important to establish a hierarchical diagnosis and treatment system during China''s healthcare system reform.Therefore, it is necessary to estimate the benefit the reform may bring.We take Zhejiang Province as an example, and adopted the system dynamics model to build the health delivery system, to emulate the hierarchical diagnosis and treatment model and the disordered model, and to evaluate the benefit.Results showed that if first option at the primary health institutions increased 10%, it could save 0.251 billion yuan, and if increased 15%, it could save 0.39 billion yuan.If the first option at the primary health institution reached 72.35% and the treatment in county reached 90%, the outpatient in tertiary hospital could reduce by 13 million, and those in primary healthcare institutions could increase by 74 million yuan.The direct healthcare cost could reduce 3.016 billion Yuan.

BACKGROUND:The knee joint acts as the body’s largest and most complex joint, which is a commonly seen perplex in patients because of synovium and cartilage diseases. Moreover, clinical physicians are often confused on the ultrasonic diagnosis of synovium and cartilage diseases.
OBJECTIVE: To review the ultrasound misdiagnosed cases of knee cartilage and synovial lesions and to summarize the common misconceptions and discrimination methods.
METHODS: A retrospective analysis was performed in the ultrasound misdiagnosed cases of knee cartilage and synovial lesions reported from 2002 to 2014, and then the common misconceptions and corresponding identification methods were summarized.
RESULTS AND CONCLUSION: High-frequency ultrasound is most likely to have six “mistaken ideas” addressing knee cartilage and synovial lesions: (1) cartilage degeneration; (2) synovial calcification; (3) echo intensity from synovial lesions; (4) blood flow in the synovium; (5) synovial effusion; (6) lesions involving intraarticular structures. High-frequency ultrasound runs through dynamical observation and contrast observation of bilateral knee joint lesions, which is a valuable imaging method for diagnosis of cartilage and synovial diseases based on vigilance at the “mistaken ideas” and mastery of the distinguishing ideas and methods.

Objective: To investigate the clinical value of transvaginal three-dimensional ultrasonography in the differential diagnosis of benign and malignant endometrial diseases after menopause. Methods: From April 2015 to April 2017, the imaging data of transvaginal three-dimensional ultrasonography of 184 patients with benign and malignant breast tumors in the Second People's Hospital of Yuhang District were retrospectively analyzed.The peak systolic flow velocity, resistance index, peak systolic velocity, intimal arterial resistance index and blood flow display rate of uterine artery of benign and malignant endometrial diseases were compared. Results: The accuracy, sensitivity and specificity of transvaginal three-dimensional ultrasonography in the diagnosis of endometrial diseases were 91.30%(168/184), 92.00%(46/50), 91.04%(122/134), respectively.There were no statistically significant differences in the peak systolic flow velocity, resistance index, peak systolic velocity of patients with benign and malignant endometrial diseases by transvaginal three-dimensional ultrasonography(t=1.17, 0.88, 0.51, all P>0.05). The intimal arterial resistance index of patients with malignant endometrial diseases by transvaginal three-dimensional ultrasonography was significantly lower than patients with benign endometrial diseases(t=2.59, P<0.05). The blood flow display rates of uterine artery of patients with malignant endometrial diseases by transvaginal three-dimensional ultrasonography were 19.40%(26/134), 92.00%(46/50). The blood flow display rate of uterine artery of patients with malignant endometrial diseases by transvaginal three-dimensional ultrasonography was significantly higher than patients with benign endometrial diseases(χ²=7.26, P<0.05). Conclusion Transvaginal three-dimensional ultrasonography in the differential diagnosis of benign and malignant endometrial diseases after menopause has higher accuracy, sensitivity and specificity.

Objective To observe the correlation of intrapulmonary TREM-1 with endoplasmic reticulum stress in mice with acute lung injury (ALI).Methods Balb/c mice were tracheally injected with lipopolysaccharide(LPS,5 mg/kg) to induce ALI.Real-time PCR and Western blot were used to detect the expressions of TREM-1,CHOP and GRP78.The correlation of TREM-1 with endoplasmic reticulum-related proteins was analyzed.LPS (100 ng/mL) was used to induce inflammation in mouse primary peritoneal macrophages,and expressions of TREM -1,CHOP and GRP78 mRNA were detected by real-time PCR.The effect of TREM-1 activation on the expressions of CHOP and GRP78 was observed in macrophages.Results The expressions of TREM-1,CHOP and GRP78 mRNA were increased in ALI mice.TREM-1 mRNA expression was positively correlated with CHOP and GRP78 mRNA expression.In vitro,LPS up-regulated the expressions of TREM-1,CHOP and GRP78,and TREM-1 was positively correlated with CHOP and GRP78.Activation of TREM-1 increased CHOP and GRP78 mRNA expressions.Conclusions TREM-1 is positively related to the endoplasmic reticulum stress.The activation of TREM-1 enhances endoplasmic reticulum in mouse macrophages.

Objective:To analyze the acupoint selection law of acupuncture for autism spectrum disorder (ASD) using data mining techniques.Methods:Literature related to acupuncture for ASD was retrieved from the CNKI, SinoMed, VIP, Wanfang, and PubMed databases from the establishment of the databases to April 1, 2022, and then a database of acupuncture prescriptions was established. The frequency analysis of acupoint use was performed using Microsoft Excel 2019; the Apriori algorithm was used to analyze the association law of acupoints/acupoint areas; SPSS 26.0 was used to perform intergroup cluster analysis.Results:A total of 97 relevant articles with 97 acupuncture prescriptions and 98 acupoints/acupoint areas were included. The most frequently used acupoint was Shenmen (HT 7). The acupoint area of Jin's three-needle therapy and the Governor Vessel acupoints are commonly used. The most frequently occurring part of the acupoint/acupoint area was the head, and the most commonly used specific acupoint was the rendezvous acupoint. Association rule analysis yielded 40 groups of acupoints/acupoint areas, and the most commonly used combination was Laogong (PC 8) and Shenmen (HT 7). Four categories were extracted among high-frequency acupoints/acupoint areas by cluster analysis.Conclusion:Acupuncture treatment for ASD mainly selects the head acupoints, mainly selecting the acupoint area of Jin's three-needle therapy and the Governor Vessel acupoints, and paying attention to the use of specific acupoints.
