ABSTRACT
Objective:To investigate the clinical efficacy of ultrasound-guided vacuum-assisted excision (VAE) in the treatment of breast benign phyllode tumor and the risk factors of local recurrence after operation.Methods:A total of 256 cases of patients with breast benign phyllode tumor admitted to Yuncheng Central Hospital from January 2012 to January 2020 were included in the retrospective study, they were all female, of which 160 cases received ultrasound-guided VAE surgical treatment and 96 cases received open surgical treatment. Measurement data were expressed as mean ± standard deviation ( ± s), and t-test was used for comparison between groups. The Chi-square test or Fisher exact probability method was used to compare the data groups. Univariate analysis was performed on the factors related to the local recurrence of benign phyllode tumor after surgery, and then the factors with statistically significant differences in the univariate analysis were further incorporated into multivariate Logistic regression analysis. Results:Univariate analysis results showed that the maximum diameter of tumor ≥25 mm and the history of ipsilateral breast fibroadenoma were associated with postoperative local recurrence of breast benign phyllodes tumor ( P<0.05). Multivariate Logistic regression analysis results showed that tumor diameter ≥25 mm was an independent risk factor for postoperative local recurrence of breast benign phyllodes tumor ( P<0.05). Conclusion:Ultrasound-guided VAE in the treatment of breast benign phyllodes tumor patients with maximum diameter less than 25 mm can reduce the postoperative local recurrence rate, and patients with tumor maximum diameter greater than 25 mm should have the higher local recurrence risk.
ABSTRACT
Objective:To investigate the correlation between serum albumin and hypoalbuminemia (HA) and the outcome after endovascular mechanical thrombectomy (EMT) in patients with stroke caused by acute anterior circulation large vessel occlusion.Methods:Stroke patients caused by acute anterior circulation large vessel occlusion received EMT treatment at the Department of Emergency Stroke, the Affiliated Hospital of Jining Medical University from June 2020 to August 2022 were retrospectively included. The demographic information, baseline clinical data, endovascular treatment parameters, and clinical outcomes of the patients were collected. HA was defined as serum albumin <35 g/L within 24 h of admission, and poor outcome was defined as the modified Rankin Scale score >2 at 90 d after onset. Multivariate logistic regression analysis was used to identify the independent influencing factors for poor outcomes. Results:A total of 177 patients were included, with a median age of 66 years, and 126 (71.19%) were males. Thirty-nine patients (22.03%) had HA, and 119 (67.23%) had poor outcomes. The proportion of pulmonary infection in the HA group was significantly higher than that in the non-HA group ( P<0.05). Multivariate logistic regression analysis showed that lower serum albumin (odds ratio [ OR] 4.102, 95% confidence interval [ CI] 1.316-16.451; P=0.028), postprocedural neurological deterioration ( OR 6.326, 95% CI 1.263-48.318; P=0.042) and pulmonary infection ( OR 5.873, 95% CI 1.028-24.452; P=0.018) were significantly independently associated with the poor outcomes. Conclusions:The HA group has a higher incidence of postprocedural pulmonary infection. Lower serum albumin, postprocedural neurological deterioration and pulmonary infection are the independent risk factors for the poor outcomes in patients with anterior circulation ischemic stroke who had successful recanalization after EMT.
ABSTRACT
Objective:To investigate the clinical characteristics, treatment and prognosis of newly-treated patients with primary central nervous system lymphoma (PCNSL).Methods:Clinical data of 117 newly-treated PCNSL patients who were admitted to the First Hospital of Jilin University, the Fifth Medical Center of Chinese PLA General Hospital, Harbin Medical University Cancer Hospital, and Cancer Hospital of Chinese Academy of Medical Sciences & Peking Union Medical College from August 2009 to February 2018 were retrospectively analyzed. The patients' age, sex, Eastern Cooperative Oncology Group (ECOG) physical status (PS) score, pathological type, involvement of deep brain tissue, number of lesions, cerebrospinal fluid protein concentration, International Extranodal Lymphoma Study Group (IELSG) score, Memorial Sloan Kettering Cancer Center (MSKCC) score, treatment strategy, and response after the first-line therapy were analyzed using univariate and multivariate Cox proportional hazards models to identify the independent influencing factors for progression-free survival (PFS) and overall survival (OS) of PCNSL patients. Kaplan-Meier method was used for survival analysis.Results:In 117 newly-treated PCNSL patients, 59 cases (50.4%) presented with increased intracranial pressure or focal neurological symptoms at diagnosis; there were 65 cases (55.6%) with single lesions and 52 cases (44.4%) with multiple lesions; 1 patient (0.9%) had lymphoma of T-cell origin, and 116 cases (99.1%) had diffuse large B-cell lymphoma (DLBCL). Among 95 evaluable patients, 41 patients (43.2%) achieved complete remission (CR), 20 patients (21.1%) achieved partial remission (PR), 16 patients (16.8%) achieved stable disease (SD), and 18 patients (18.9%) had progressive disease (PD). In 117 patients with median follow-up of 66.0 months (95% CI 57.9-74.1 months), the median PFS and OS were 17.4 months (95% CI 11.5-23.3 months) and 45.6 months (95% CI 20.1-71.1 months), respectively. The 2-, 3- and 5-year PFS rates were 41.2%, 28.6% and 19.3%, and OS rates were 63.7%, 52.4% and 46.3%, respectively. Univariate Cox regression analysis showed that baseline high-risk MSKCC score group was an adverse prognostic factor for PFS ( P = 0.037), and the first-line chemotherapy with ≥4 cycles of high-dose methotrexate (HDMTX), HDMTX in combination with rituximab, ≥4 cycles of rituximab in combination with HDMTX, and achieving CR or ≥PR after the first-line treatment reduced the risk of disease progression and prolonged the PFS time (all P <0.01); age >60 years old, ECOG-PS score of 2-4 points, elevated cerebrospinal fluid protein concentration, high-risk IELSG score, and high-risk MSKCC score were adverse prognostic factors for OS, and ≥4 cycles of HDMTX and achieving CR or ≥PR after the first-line treatment were favorable factors for OS. Multivariate Cox regression analysis verified that rituximab in combination with HDMTX (yes vs. no: HR = 0.349, 95% CI 0.133-0.912, P = 0.032) and achieving ≥PR after the first-line chemotherapy (yes vs. no: HR = 0.028, 95% CI 0.004-0.195, P < 0.001) were independent favorable factors for PFS; age >60 years old (>60 years old vs. ≤60 years old: HR = 10.878, 95% CI 1.807-65.488, P = 0.009) was independent unfavorable factor for OS, while ≥4 cycles of HDMTX treatment (≥4 cycles vs. <4 cycles: HR = 0.225, 95% CI 0.053-0.947, P = 0.042) was independent favorable factor for OS. Conclusions:The older the PCNSL patients at initial treatment, the worse the prognosis. Intensive and continuous treatment for achieving deeper remission may be the key for improving the outcome of PCNSL patients.
ABSTRACT
ObjectiveTo explore the psychological and behavioral characteristics of understanding Chinese garden path sentences in children with high-functioning autism (HFA). MethodsFrom April to August, 2019, 35 children with HFA and 35 age-matched typically developing (TD) children were recruited by social recruitment method in the Key Laboratory of Speech and Hearing of East China Normal University in Shanghai. The Garden Path Sentence Comprehension Test was designed based on the psycholinguistic method, and the mental process and the ability of understanding garden path sentences were tested by the agent task experiment paradigm. Finally, the processing strategies and error types of Chinese spoken garden path sentences for HFA children were explored. ResultsThe score in understanding garden path sentences was lower (t = -2.941, P < 0.01), and the reaction time in processing garden path sentences was significantly longer (t = 6.132, P < 0.001) in HFA children than in TD children, however, there was no significant difference in the number of childern mastering garden path sentences between two groups (χ2 = 2.954, P > 0.05). In terms of the error types of "animate noun + verb + animate noun + 's + noun" (AVA) and "animate noun + verb + inanimate noun + 's + noun" (AVI) garden path sentences, both groups showed more errors in "pursuit of correct word order" than in "pursuit of semantically correct" (t > 2.503, P < 0.05). In "inanimate noun + verb + animate noun + 's + noun" (IVA) sentences, HFA children showed less erros in "pursuit of correct word order" than in "pursuit of semantically correct" (t = -6.523, P < 0.001), however, no difference was found between them in TD children (t = 2.024, P > 0.05). ConclusionThe processing and comprehension ability of Chinese spoken garden path sentences in HFA children aged five to seven yeas are poor. HFA children are more sensitive to semantics, and garden path sentences with semantic violations are more likely to lead to HFA children's understanding errors. In the garden path sentence patterns of AVA and AVI, HFA children appear similar sentence understanding and processing strategies as TD children. In the garden path of IVA, HFA children use a sentence processing strategy combining word order and semantics, but semantics play a more prominent role, while TD children use a more stable word order processing strategy.
ABSTRACT
Objective:To analyze general information, diagnosis and treatment of digestive endoscopy departments in county-level hospitals of Yunnan Province, thus to provide evidence for improving the endoscopic diagnosis and therapy in these hospitals.Methods:An online survey was performed to collect quality-related information of digestive endoscopy centers (departments) at county-level hospitals of Yunnan from January 2019 to January 2020, including endoscopic equipment, endoscopic techniques, staffing, number of operations, and quality control.Results:A total of 143 county-level hospitals were involved in this study. Each hospital owned only 1.74 endoscopy operation rooms on average, 1.42 regular endoscopy workstation, 4 endoscopes. There were only 10 endoscopic ultrasonography workstations and 2 enteroscopy workstations respectively installed in these hospitals. Endoscopic retrograde cholangiopancreatography was independently performed in only 4 hospitals. There were 392 professional endoscopists in all 143 hospitals, 18.62% (73/392) of whom were able to perform endoscopic therapy of grade 4, while only 6.12% (24/392) of whom could perform endoscopic submucosal dissection (ESD) independently. In 2019, the early diagnostic rate of gastrointestinal tract cancer in these hospitals was 19.48% (1 133/5 817). The early diagnostic rate was 21.04% (276/1 312) for esophageal cancer, 19.53% (397/2 033) for gastric cancer, and 18.61% (460/2 472) for colorectal cancer. The colorectal adenoma detection rate was 12.83% (12 207/95 148). The rate of reaching cecum during colonoscopy was 70.49% (67 067/95 148). The complete resection rate of ESD was 12.54% (221/1 763).Conclusion:The general situation of digestive endoscopy in county-level hospitals of Yunnan is far from being well-developed, which may be attributed to slow upgrading of equipments, inadequate training of endoscopic professionals and undemanding quality control. It is highly significant to improve medical service and quality of diagnosis and treatment of digestive endoscopy in these hospitals, on the basis of a complete endoscopy quality control system with a high standard.
ABSTRACT
Objective:To investigate characteristics of the 18F-flurodeoxyglucose ( 18F-FDG) uptake intensity and ranges in distinct hepatic alveolar echinococcosis lesions. Methods:The clinical data of 39 patients with position emission tomography during Jan 2017 to Dec 2019 in the First Affiliated Hospital of Xinjiang Medical University were enrolled. Among them, there were 17 males and 22 females, aging from 15 to 65 years (median 34 years). Lesions were classified into six groups based on heterogenic scales of calcification and liquefaction: A. non-calcified and non-liquefied ( n=7); B. obvious calcified and non-liquefied ( n=7); C. partial calcified and partial liquefied( n=10); D. obvious calcified and partial liquefied ( n=5); E. partial calcified and subtotal liquefied ( n=5); F. obvious calcified and subtotal liquefied ( n=5). Tumor to background ratio (TBR) and width (W) of lesion infiltrative boundary were measured and calculated. Statistical comparison using Mann-Whitney U test as well as correlation analysis was performed. Results:TBR values [ M( Q1, Q3)] for each group were 4.40(3.66, 7.03), 2.55(1.69, 3.60), 3.73(3.37, 5.21), 2.90(2.75, 3.60), 3.80(3.49, 6.36), 2.49(2.21, 3.97), among which A>B, A>D, A>F, C>B, E>B ( U=3.0, 4.0, 4.5, 11.0, 5.0, all P<0.05); From the perspective of the calcification in each group, it was found that the lighter the calcification was, the greater the TBR value was. W values [ M( Q1, Q3)] for each group were [12.5(10.0, 19.5), 11.2(10.5, 12.5), 12.2(10.9, 13.2), 7.8(7.3, 9.3), 10.0(7.3, 13.4), 7.3(6.8, 7.6)] mm, among which A>D, A>F, B>D, B>F, C>D, C>F (all U=0, all P<0.05); According to the degree of calcification and liquefaction of lesions in each group, the lighter the calcification was, the greater the W value was; The heavier the liquefaction was, the smaller the W value was. A mild strength linear correlation has been observed between the TBR value and W value ( r=0.4136, P<0.05). Conclusions:Less calcification and liquefaction implicated higher 18F-FDG uptake intensity and wider range. Radical resection margins and tissue sampling should be individualized based on different lesion features in surgical treatment.
ABSTRACT
Objective:To investigate the diagnostic value of 99mTc-methylenediphosphonate(MDP) whole body bone scintigraphy in early brucellosis patients with bone and joint injuries. Methods:According to the Diagnosis for Brucellosis (WS 269-2019), combined with epidemiological history, clinical manifestations and serological tests, from November 2020 to April 2021, 15 early brucellosis patients (the course of disease was within 6 months) who had not received any drug treatment diagnosed at the Department for Brucellosis Prevention and Control, Qinghai Institute for Endemic Disease Prevention and Control were selected as the research subjects, and 99mTc-MDP whole body bone scintigraphy was performed on the patients to evaluate the images and analyze the pathological changes. Results:The 99mTc-MDP whole body bone scintigraphy of 15 patients with early brucellosis showed abnormalities, and the abnormal concentration of radionuclides mainly occurred in the 8th to 12th thoracic vertebrae (T8-12), the 1st to 2nd lumbar vertebrae (L1-2) and L4-5. Among them, the thoracic vertebrae abnormalities were T8, T9, T10, T11 and T12 in 1 case each; lumbar vertebrae abnormalities were 1 case of L1, 1 case of L2, 4 cases of L4, and 5 cases of L5. Conclusions:The 99mTc-MDP whole body bone scintigraphy is abnormal in patients with early brucellosis. Bone scintigraphy has certain value in the diagnosis of bone and joint injuries in patients with early brucellosis.
ABSTRACT
Objective:To simulate the biomechanical characteristics of the real human thoracic cavity with a multi-spring group variable damping structure, and to design a new cardiopulmonary resuscitation training manikin based on the simulated thoracic biomechanical characteristics combined with the original electronic feedback system, and to test its application effect in cardiopulmonary resuscitation (CPR) teaching.Methods:A total of 60 undergraduate students majoring in five-year clinical medicine of Batch 2019 in Naval Medical University were selected as the research objects and were randomly divided into the experimental group and the control group, with 30 students in each group. The control group used the traditional manikin for CPR training, and the experimental group used the new type of manikin for CPR training based on the control group. After the training, the two groups of personnel were assessed for single skill. The single skill was mainly manual CPR operations, including artificial respiration and chest compressions. The theory and skill operation assessment of CPR and satisfaction for teaching method in the two groups were compared. SPSS 23.0 was used for statistical analysis.Results:The students in the experimental group scored (54.33±3.09) points in the single skill operation assessment, which were significantly better than that of the students in the control group [(52.33±3.08) points], and the difference was statistically significant ( P<0.05). The follow-up questionnaire showed that the students in the experimental group had a better evaluation of the teaching and training effect of the new type of manikin. Conclusion:Compared with the traditional manikin, the new CPR manikin can simulate the CPR emergency scene of the real human body, which can effectively improve the CPR teaching effect of standardized training for medical students, and help the standardization, normalization, and popularization of CPR technology in China.

Urinary tract infection (UTI) is one of the most common infectious diseases. It has the characteristics of high recurrence rate and prolonged course. At present, the problem of antibiotic resistance is becoming more and more serious, the incidence of adverse reactions is high, and the disadvantages of long-term administration appear, which brings severe challenges to the treatment of recurrent urinary tract infection. The prevention and treatment of UTI recurrence has become the focus of research. Recurrent urinary tract infection is related to the immune regulation mechanism of the body. Administration of immune regulation can provide new ideas for prevention and treatment. The vaccine based on immune regulation to prevent rUTI has made some progress. It can not only reduce the frequency of recurrences, but also decrease related symptoms. At the same time, the vaccine has good tolerance, high safety and good application prospect. This paper aims to summarize the progress of immune regulation and immune vaccines in vivo and clinical research.
ABSTRACT
Objective:To evaluate the safety and efficacy of endoscopic retrograde biliary drainage (ERBD) for acute obstructive suppurative cholangitis (AOSC) in the elderly.Methods:A retrospective analysis was performed on the clinical data of AOSC patients admitted to the First Affiliated Hospital of Xinjiang Medical University from January 2018 to January 2020. Patients aged 75 years and over ( n=49) were assigned to the elderly group and patients under 75 years old were assigned to the control group ( n=63). General data, American Society of Anesthesiologists (ASA) grading, procedure-related indicators, incidence of postoperative complications and mortality were compared. Results:There were significant differences in age (82.6±5.1 years VS 64.6±4.5 years, t=19.98, P<0.001), albumin levels (29.1±5.9 g/L VS 34.6±8.8 g/L, t=-3.94, P<0.001) and ASA grade ( χ2=8.37, P=0.015) in the elderly group and the control group . The elderly group were accompanied by more basic diseases, i.e. hypertension [57.14% (28/49) VS 34.9% (22/63), χ2=5.51, P=0.019], coronary heart disease [55.1% (27/49) VS 27.0% (17/63), χ2=9.14, P=0.003], chronic obstructive pulmonary diseases/asthma [24.5% (12/49) VS 6.3% (4/63), χ2=7.41, P=0.006]. There were no significant differences in the operation time (31.4±8.1 min VS 30.4±8.0 min, t=-0.61, P=0.543) or hospital stay (6.1±1.7 days VS 5.7±1.4 days, t=1.35, P=0.182). The incidences of postoperative complications were 14.3% (7/49) in the elderly group and 12.7% (8/63) in the control group, showing no significant difference ( χ2=0.06, P=0.807). No ERBD-related death was observed in either group during hospital stay. Conclusion:For elderly patients with AOSC over 75 years old, emergency ERBD, which can quickly relieve the disease, is safe and effective. Advanced age is not an absolute contraindication for emergency ERBD.
ABSTRACT
Objective:To investigate the feasibility, safety and efficacy of simultaneous combined surgery for hepatic and renal cystic echinococcosis (CE).Methods:Clinical data of consecutive 11 hepatic and renal CE patients undergoing surgical treatment at the First Affiliated Hospital of Xinjiang Medical University from Oct 2009 to Feb 2017 were analyzed retrospectively.Results:There were 8 males and 3 females, median age was 44 years (22-60 years). Main symptoms were abdominal and/or flank pain and fever; nine and 2 patients respectively had cysts in liver plus right kidney and left kidney; median volume of cyst load for each patient was 944.1 cm 3 (67.1-9 310.4 cm 3). All patients were treated simultaneously by combined surgery, including total and subtotal cystectomies, hepatic or renal resections as well as extra lesions resection. All surgeries went uneventfully, radical rate was 63.6% (7/11), There was no postoperative liver or kidney dysfunctions. Median operative time, bleeding and length of hospital stay were 2.5 h (1.4-4.5 h), 100 ml (50-200 ml) and 7 d (5-10 d) respectively. All were followed-up for median 42 mouths (34-123 mouths) and all doing well without disease recurrence. Conclusions:Simultaneous combined surgery for recurrent or primary hepatic and renal double organ CE patients could be a feasible and effective approach.
ABSTRACT
Objective:To investigate the safety and feasibility of hepatectomy in the treatment of hepatic alveolar echinococcosis with secondary cavernous transformation of the portal vein.Methods:The clinical data of 7 patients undergoing surgery at the First Affiliated Hospital of Xinjiang Medical University from Jan 2010 to Dec 2019 were retrospectively analyzed.Results:There were 1 case of cavernous type Ⅰ transformation of the portal vein and 6 cases of type Ⅱ. All patients underwent partial hepatectomy. The average operation time was (9.24±4.09) h. Two patients underwent resection of cavernous segment of portal vein and reconstruction by graft, Albendazole was taken orally for 2 years after discharge. Anticoagulants were taken orally in patients with artificial vascular reconstruction. No recurrence and vascular complications were found. Five patients underwent palliative resection without resection of the cavernous segment of the portal vein. During the follow-up, cavernous transformation of the portal vein progressed in 3 patients, 2 of them esophageal varices rupture and bleeding.Conclusion:Radical hepatectomy and revascularization are the first choice for the treatment of hepatic alveolar echinococcosis complicated with secondary cavernous transformation of portal vein the result was fair.

ABSTRACT
Objective:To compare the outcomes of combined lingual mucosal graft with buccal mucosal graft urethroplasty and combined lingual mucosal graft with ADM (acellular dermal matrix) urethroplasty for the treatment of repair failed hypospadias.Methods:From February 2017 to February 2019, 26 patients with failed hypospadias repairs were treated with combined lingual mucosal graft with buccal mucosal graft urethroplasty (14 cases in Group A), and combined lingual mucosal graft with ADM urethroplasty (12 cases in Group B). The mean age of Group A was (29.5±1.2) years (range 18.0-41.0 years), and (26.5±0.8) years (range 20.0-38.0 years) in Group B. The previous operation times was mean (3.6±0.7)(range 2-5 times) and (4.6±0.8)(range 3-5 times) in Group A and Group B respectively. Operation method: All patients were nasally intubated, the remaining curvature was corrected, the fibrous tissue or scar was removed, and the defected urethra was measured. In Group A, the lingual mucosa was spread and fixed to the corpora cavernosa over the midline as the urethral plate, the buccal mucosa was covered the lingual mucosa as ventral urethra, both the mucosa lateral edges was sutured. In Group B, the lingual mucosa was harvested and fixed to the corpora cavernosa the same as in Group A, the ADM was made appropriate length and width, covered and sutured with the lingual mucosa. The lingual mucosa was harvested mean (5.0±0.2)cm(range 4-6cm)long, mean (1.2±0.2)cm (range 1.0-1.5cm)wide and mean (5.0±0.2)cm(range 5-6cm)long, mean (1.2±0.2)cm (range 1.0-1.5cm)wide in Group A and Group B respectively( P<0.05). In Group A, the buccal mucosa was harvested mean (4.1±0.2)cm(range 3.5-5.5cm)long, mean (1.2±0.2)cm wide. Criteria for successful repair of hypospadias were set as: ①The appearance of the penis is nearly normal; ②The penis curvature was corrected; ③Urethra orifice in normal position; ④Urine flow line is normal. The outcomes of the two groups were analyzed and compared, statistical analysis was done using SPSS 18.0 software. Results:The mean follow-up time was (16.3±1.6)(8-24) months. The age, number of preoperative surgeries, number of previous oral mucous membranes, and length of urethral defects were no statistically significant differences between the two groups in A and B( P>0.05). The length of oral mucosa was harvested during the operation between group A and Group B were statistically significant differences( P<0.05). The incidence of oral complications in group A and B: Oral pain 7/14, 1/12; The feeling of tension in mouth 8/14, 1/12; The numbness in the oral 8/14, 1/12, A and Group B were statistically significant differences( P<0.05). The incidence of urethral complications in group A and Group B: the urethra fistula 1/14, 4/12; the urethral stricture 2/14, 6/12, there were statistically significant differences between the two groups ( P<0.05). Penile curvature 2/14, 1/12, ( P>0.05). The success rate was 12/14 and 5/12 in Group A and B respectively, with statistical difference( P<0.05). Conclusions:Combined lingual mucosal graft with buccal mucosal graft urethroplasty could be a good choice for repeated failed hypospadias repairs. Combined lingual mucosal graft with ADM urethroplasty has many complications and less success, should be performed in caution.
ABSTRACT
Human alveolar echinococcosis is a chronic infectious disease caused by Echinococcus multilocularis infection. It predominantly injuries the liver and grows like the malignant tumor. The therapeutic options and prognosis depend on types of human alveolar echinococcosis, clinical stages, biological activity, vascular invasion, pathological characteristics, and patient's immune status. However, despite of multiple classification methods, there are still lacking of comprehensive typing schemes. which leads to inappropriate diagnosis and therapy. This research systematically reviewed the recent studies on human alveolar echinococcosis at home and abroad and analyzed the classifications based on ultrasound, computer tomography, magnetic resonance imaging, positron emission computed tomography, serology and pathology, and some novel technologies and summarized the individual advantage and disadvantage for each classification Relationships and their advantages plus disadvantages have been assessed comprehensively. Meanwhile, the possible reference factors or theoretical basis for optimized future classification are proposed, in order to establish a unified classification system to provide guidance for clinical diagnosis and treatment.
ABSTRACT
Objective To investigate the status of radiological protection in Baoji City. Methods Using the questionnaire survey method, the survey forms were sent to the radiology clinics and other relevant units in the counties and districts of the city to investigate the basic situation of radiology and treatment of medical and health institutions, basic information of radiology and treatment equipment, personal information of radiation workers, and health monitoring of radiation workers. Results There is 1.13 X-ray diagnostic equipment per 10, 000 people, 0.015 radiotherapy equipment per 10, 000 people in Baoji City, and One million people own 11.4 CTs. There are 1, 102 radiation workers in Baoji City, and 2.92 per 10, 000 people. The occupational health check rate of medical radiation personnel was 87.7% within 2 years, the personal dose monitoring rate was 90.4%, the radiation worker training rate was 73.6% within 2 years, about the holding rate of "Radiation Staff Certificate" in Baoji City was 73.0%, and the occupational health file rate was 89.2%. The evaluation indexes of various health monitoring were lower, especially in township hospitals (35.7%～50.8%). Conclusion On the whole, the number of radiological diagnosis and treatment equipment is small, and Class A large equipment is almost blank. The city is stronger than the county in health monitoring. The status of health monitoring is very different from urban to rural areas.
ABSTRACT
In order to strengthen the management of disinfection quality of endoscopes, Quality Control Center of Digestive Endoscopy and Nosocomial Infection Control Center of Yunnan Province investigated the diagnosis, treatment, cleaning and disinfection conditions and disinfection quality of digestive endoscopes in some medical institutions of Yunnan Province by web questionnaire from April to May in 2019, and 277 valid questionnaires were finally obtained. SPSS 19.0 statistical software was used to analyze the influencing factors of cleaning and disinfection process and the infection control implementation of digestive endoscopes in 227 secondary and tertiary hospitals. The results showed that the number of decontamination people who had received systematic training in Yunnan Province was significantly lower than that in other areas of China. The hospital level, the number of decontamination personnel, and decontamination methods affected the implementation of cleaning and decontamination process and infection control, while the allocation of decontamination supplies had no effects. It is important to establish an effective mechanism for the normalized implementation of cleaning and disinfection of digestive endoscopes.
ABSTRACT
Objective:To explore the curative effect of laparoscopic surgery for hepatic cysticercosis.Methods:Search the literature from February 2010 to February 2020 on literature platforms such as Wanfang Data, VIP, CNKI, Pubmed, ScienceDirect, Web of Science, etc. the key words were "肝囊型包虫病" , "细粒棘球蚴" , "手术" , "开腹手术" , "腹腔镜" , "微创手术" , " echinococcosis " , " liver or hepatic " , " laparoscopic or minimal invasive " . Data on intraoperative indicators (e.g., operation time, bleeding volume), postoperative complications, hospital stay, recurrence rate, etc. in the literature included in the study were extracted and meta-analyzed.Results:A total of 9 articles were included, including 2 prospective studies and 7 retrospective case-control studies. A total of 1031 patients were enrolled, including 272 in the laparoscopic group and 759 in the laparotomy group. The results of the meta-analysis showed that the total postoperative complication rate in the laparoscopic group was lower than that in the laparotomy group ( OR=1.64, 95% CI: 1.10-2.45, P<0.05). Incision-related complications in the laparoscopy group and laparotomy group the difference was statistically significant ( OR=2.81, 95% CI: 1.03-7.70, P<0.05), and the hospital stay in the laparoscopic group was shorter ( SMD=1.21, 95% CI: 0.47-1.96, P<0.05). There was no significant difference between the two groups in operation time, postoperative bile leakage, residual cavity infection and effusion, and postoperative recurrence rate ( P>0.05). Conclusions:Under the premise of strictly grasping the indication of laparoscopic surgery, the incidence of complications after laparoscopic surgery is low, the hospitalization time is short.
ABSTRACT
OBJECTIVE@#To explore the synergistic immunomodulatory mechanism of interferon alpha-1b, interleukin-2 and thalidomide (ITI) regimen on patients with acute myeloid leukemia (AML).@*METHODS@#Sixty eight untreated de novo or relapsed or refractory or maintenance therapy patients with AML admitted in the Affiliated Cancer Hospital of Zhengzhou University and the other 11 medical units from March 2016 to May 2019 were treated with ITI regimen. Peripheral blood specimen per patient was collected into EDTA-K3 anticoagulation vacuum tube before the administration of ITI and 3 months after the treatment; peripheral blood lymphocyte subsets and perforin and Granzyme B expression were analyzed by using flow cytometry; the levels of VEGF, IFN-γ, TNF-α and IL-6 in the plasma were detected by using a cytometric bead array. Thirty-five healthy subjects from the hospital physical examination centre were selected as normal controls.@*RESULTS@#The ratio of CD4@*CONCLUSION@#The ITI regimen can raise the ratio of CD4
