Objective To analyze solitary fibrous tumor (solitary fibrous tumor, SFT) ’s clinical manifestations, patholog-ical features, immunohistochemical phenotype, and follow-up, discuss the diagnosis, differential diagnosis and progno-sis. Methods Ten cases of SFT were analyzed by clinical data and follow-pathological characteristics study and im-munohistochemical staining of Vimentin, CD34, Bcl-2, CD99, SMA and β-catenin. Results There were 6 males and 4 females with ranging in age from 31 to 78 years (mean 53.2 years old). SFT in four cases originated from the visceral pleura, two cases from parietal pleura,one from the skin of the chest wall, one from the neck, one from the medi-astinum, one from subcutaneously. Microscopic examination of tumor tissue was mainly composed of spindle cells, dif-ferent levels of visible cells and cell-rich areas of sparse areas, tumor cells were short spindle or oval, mitotic due to the severity varies. During the visible rich collagen fibers, may be associated with hyaline degeneration or myxoid change. Immunohistochemistry revealed the tumor cells expessed Vimentin, CD34, Bcl-2, CD99 and β-catenin, SMA focal or weakly positive. Conclusion SFT may occur in various sites of the body. The clinicopathological features and immunohistochemical profile are helpful to identify SFT. Its biological behavior is consistent with its histological mor-phology and growth the way. If tumor could be removed completely, the patients may have a good prognosis;some have low-grade malignant or malignant behaviour, manifesting as local recurrence or metastasis. Patients need long-term follow-up.

OBJECTIVETo observe sperm motion parameters in pre-freeze and post-thaw semen samples using computer-assisted sperm analysis (CASA) system.

METHODSSemen analyses of 238 samples before freezing and after thawing were separately performed by Hamilton-Thorne Sperm Analyzer.

RESULTSSperm motility in post-thaw samples was significantly decreased. There was significant correlation and difference between pre-freeze and post-thaw samples in sperm motion parameters, including average path velocity (VAP), straight line velocity (VSL), curvilinear velocity (VCL), amplitude of lateral head displacement (ALH), straightness (STR) and linearity (LIN), except heat cross frequency (BCF). The percentage of sperm movement velocity parameters (VAP, VSL and VCL) and moving pattern parameters (ALH) significantly decreased, while that of LIN and STR significantly increased in post-thaw samples.

CONCLUSIONCASA system is of clinically applied value and is a useful tool for evaluating sperm motion parameters in pre-freeze and post-thaw semen samples.

Objective To study the safety and efficacy of laparoscopic resection of hemangioma in the right posterior hepatic section without any blood flow occlusion.Methods Patients with hemangiomas in the right posterior section of liver operated from January 2016 to June 2018 in the Affiliated Hospital of Youjiang Medical College for Nationalities were studied retrospectively.There were 19 females and 9 males.The average age was (37.9 ± 6.1).The operation methods,perioperative factors,hospitalization cost and follow-up outcomes were recorded and analyzed.Results 28 patients with hemangiomas were treated with laparoscopic resection of right posterior hepatic section without any blood flow occlusion.An ultrasound scalpel was applied to split the liver in 27 patients,and ultrasound scalpel combined with Ligasure to split the liver in 1 patient.The mean diameter of the hepatic hemangiomas was (6.7 ± 1.3) cm.The intraoperative blood loss was (330.4 ± 139.0) ml and the operation time was (87.4 ±27.9) min.One patient required conversion to open surgery due to rupture and bleeding of the hemangioma.The conversion rate was 3.6％ (1/28).The postoperative drainage time was (45.4 ± 18.9) h.The postoperative hospitalization time was (7.5 ± 1.3) d,and the hospitalization cost was (3.1 ± 0.5) ten thousand yuan.No death or serious complications occurred.No reoperation was needed.The follow-up period ranged from 1 to 30 months,and all the patients were well on follow-up.Conclusions Laparoscopic resection of hemangioma in the right posterior hepatic section without any blood flow occlusion was safe and efficacious.This method can be used for hemangiomas in the right posterior section of liver.

Objective:To study the feasibility and safety in treatment of trauma to right posterior liver using laparoscopic surgery with patients in the left semiprone position.Methods:The clinical data of consecutive patients who were diagnosed to have trauma to the right posterior liver and were treated with laparoscopic surgery with patients in the left semiprone position at the Department of Hepatobiliary Surgery, the Affiliated Hospital of Youjiang Medical University for Nationalities between February 2016 and August 2020 were retrospectively analysed. The patients’ gender, age, mechanisms of injury, operative methods, operative time, amounts of abdominal effusion, degrees of liver injury, extents of intraoperative bleeding, amounts of postoperative drainage, lengths of postoperative hospital stay, and major postoperative complications were recorded and analyzed.Results:Among the 18 patients, there were 16 males and 2 females, aged (41.6±14.4) years. The mechanisms of liver trauma were caused by fall injury ( n=10), traffic accidents ( n=4), blunt injury ( n=2) and penetrating injury ( n=2). The levels of injuries were level Ⅲ in 16 patients and level Ⅳ in 2 patients. Laparoscopic suture repair was performed in 8 patients, partial hepatectomy in 4 patients, electrocoagulation hemostasis in 4 patients and ligation of bleeding vessels in 2 patients. All were successful in hemostasis. Abdominal effusion was (1 528.8±373.2) ml, intraoperative blood loss (80.6±16.7) ml, operation time (88.5±9.1) min, postoperative hospital stay 7 days and postoperative total drainage (93.8±13.6) ml. Ten patients were complicated with right pleural effusion, and they recovered with conservative treatment. There were no bile leakage, infection and other complications. Conclusion:Trauma to right posterior liver treated with laparoscopic with surgery patients in the left semiprone position had the advantages of adequate exposure which facilitated surgical hemostasis, resulting in minimal collateral damages and short hospital stay. The treatment was feasibility and safe.

Background: Long coronavirus disease 2019 (COVID-19) in recovered patients (RPs) is gradually recognized by more people. However, how long it will last and the underlining mechanism remains unclear. Methods: We conducted a prospective follow-up study to evaluate the long-term symptoms and clinical indices of RPs at one-year after discharge from Union Hospital, Wuhan, China between December 2020 to May 2021. We also performed the 16S rRNA sequencing of stool samples from RPs and healthy controls (HCs) and analyzed the correlation between the gut microbiota and long COVID-19. Results: In total, 187 RPs were enrolled, among them, 84 (44.9%) RPs reported long COVID-19 symptoms at one-year after discharge. The most common long-term symptoms were cardiopulmonary symptoms, including chest tightness after activity (39/187, 20.9%), palpitations on exercise (27/187, 14.4%), sputum (21/187, 11.2%), cough (15/187, 8.0%) and chest pain (13/187, 7.0%), followed by systemic symptoms including fatigue (34/187, 18.2%) and myalgia (20/187, 10.7%), and digestive symptoms including constipation (14/187, 7.5%), anorexia (13/187, 7.0%), and diarrhea (8/187, 4.3%). Sixty-six (35.9%) RPs presented either anxiety or depression (42/187 [22.8%] and 53/187 [28.8%] respectively), and the proportion of anxiety or depression in the long symptomatic group was significantly higher than that in the asymptomatic group (41/187 [50.6%] vs. 25/187 [24.3%]). Compared with the asymptomatic group, scores of all nine 36-Item Short Form General Health Survey domains were lower in the symptomatic group (all P < 0.05). One hundred thirty RPs and 32 HCs (non-severe acute respiratory syndrome coronavirus 2 infected subjects) performed fecal sample sequencing.Compared with HCs, symptomatic RPs had obvious gut microbiota dysbiosis including significantly reduced bacterial diversities and lower relative abundance of short-chain fatty acids (SCFAs)-producing salutary symbionts such as Eubacterium_hallii_group, Subdoligranulum, Ruminococcus, Dorea, Coprococcus, and Eubacterium_ventriosum_group. Meanwhile, the relative abundance of Eubacterium_hallii_group, Subdoligranulum, and Ruminococcus showed decreasing tendencies between HCs, the asymptomatic group, and the symptomatic group. Conclusion This study demonstrated the presence of long COVID-19 which correlates with gut microbiota dysbiosis in RPs at one-year after discharge, indicating gut microbiota may play an important role in long COVID-19.

OBJECTIVE: To compare the effect of 7 antipsychotic drugs on the life quality of schizophrenia patients including chlorpromazine, sulpiride, clozapine, risperidone, olanzapine, quetiapine, and aripiprazole. METHODS: A total of 1,227 stable schizophrenic patients within 5 years onset who took 1 of the 7 study medications as maintenance treatment were followed up for 1 year at 10 China sites. Patients were evaluated by the short form-36 health survey (SF-36) at the baseline and at the end of 1 year. RESULTS: The life quality was improved obviously at the end of the follow-up. There was significant difference in body pain, vitality, and mental health (P<0.05) among these antipsychotic drugs. CONCLUSION All 7 antipsychotic drugs can improve the life quality of schizophrenia patients. Atypical antipsychotic drugs, especially olazapine and quetiapine, are superior to typical antipsychotic drugs in improving life quality.

Objective To investigate the significance of superb microvascular imaging (SMI) for the detection of neovascularization in carotid atherosclerotic plaques.Methods SMI detected 28 carotid atherosclerotic plaques in 28 patients who underwent carotid endarterectomy.The SMI grade of carotid plaque neovascularization was assigned based on the following grading system:Grade 0,no neovascularization;grade 1,some neovascularization;grade 2,neovascularization observed in the shoulder of the plaque;and grade 3,widely distributed new blood vessels.SMI was used to evaluate the degree of blood flow,maximum flow velocity,and resistance index of the new vessels in the plaque.Microvascular density was measured with CD31 staining.Results Clear correlations were observed between neovascularization density on histopathological staining of the plaque and the degree of blood flow detected with SMI (rs=0.788,P ＜ 0.001).The classification of neovascular blood flow in the plaque was positively correlated with plaque thickness (rs=0.686,P=0.002).Of the 28 cases,neovascularization was detected in 23;of these 23 cases,the direction of blood flow was from the adventitia to the intima in 17 (75％) cases,while 6 (25％) cases showed an irregular direction of blood flow.The mean neovascular flow velocity was (5.620±0.131) cm/s,and the mean neovascular resistance index was 0.660 ± 0.090.Conclusion SMI is useful for the evaluation of carotid atherosclerotic plaque neovascularization.

BACKGROUND: Although intensively studied in patients with cardiovascular diseases (CVDs), the prognostic value of diastolic blood pressure (DBP) has little been elucidated in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). This study aimed to reveal the prognostic value of DBP in AECOPD patients. METHODS: Inpatients with AECOPD were prospectively enrolled from 10 medical centers in China between September 2017 and July 2021. DBP was measured on admission. The primary outcome was all-cause in-hospital mortality; invasive mechanical ventilation and intensive care unit (ICU) admission were secondary outcomes. Least absolute shrinkage and selection operator (LASSO) and multivariable Cox regressions were used to identify independent prognostic factors and calculate the hazard ratio (HR) and 95% confidence interval (CI) for adverse outcomes. RESULTS: Among 13,633 included patients with AECOPD, 197 (1.45%) died during their hospital stay. Multivariable Cox regression analysis showed that low DBP on admission (<70 mmHg) was associated with increased risk of in-hospital mortality (HR = 2.16, 95% CI: 1.53-3.05, Z = 4.37, P <0.01), invasive mechanical ventilation (HR = 1.65, 95% CI: 1.32-2.05, Z = 19.67, P <0.01), and ICU admission (HR = 1.45, 95% CI: 1.24-1.69, Z = 22.08, P <0.01) in the overall cohort. Similar findings were observed in subgroups with or without CVDs, except for invasive mechanical ventilation in the subgroup with CVDs. When DBP was further categorized in 5-mmHg increments from <50 mmHg to ≥100 mmHg, and 75 to <80 mmHg was taken as reference, HRs for in-hospital mortality increased almost linearly with decreased DBP in the overall cohort and subgroups of patients with CVDs; higher DBP was not associated with the risk of in-hospital mortality. CONCLUSION: Low on-admission DBP, particularly <70 mmHg, was associated with an increased risk of adverse outcomes among inpatients with AECOPD, with or without CVDs, which may serve as a convenient predictor of poor prognosis in these patients.
