ABSTRACT
Background An association between atmospheric fine particulate matter (PM2.5) exposure and Parkinson's disease (PD) has been suggested by previous studies, but the results of current epidemiological studies are still inconclusive. Objective To systematically evaluate the relationship between exposure to ambient PM2.5 and the risk of PD, as well as to explore potential influencing factors, aiming to provide scientific evidence for formulating early prevention strategies for PD. Methods Cochrane Library, PubMed, Web of Science, Medline, Embase, China National Know-ledge Infrastructure (CNKI), Wanfang Database, and VIP Chinese Science and Technology Journal Database were queried. The search terms included Parkinson's disease, particulate matter 2.5, and PM2.5 in both Chinese and English. Cohort studies examining the association between atmospheric PM2.5 exposure and the risk of PD were collected and searched from the inception of each database to June 26, 2023. The identified literature was screened, and the basic information of the included studies and their research subjects, outcome indicators, quantitative results of each study, as well as the information required by bias risk assessment were extracted. The Newcastle-Ottawa Scale was employed to assess the risk of literature bias. Meta-analysis, subgroup analysis, sensitivity analysis, and publication bias analysis were conducted in Stata 15.0 software. Results Twelve cohort studies were identified. A total of 17443136 participants with follow-up periods ranging from 3.5 to 22 years were included in the analysis. The meta-analysis, utilizing a random-effects model, revealed that PD risk was elevated by 6% after exposure to PM2.5 [HR=1.06 (95%CI: 1.02, 1.11), P=0.006]. The subgroup analysis demonstrated that exposure to PM2.5 increased PD risk by 6% in North America [HR=1.06 (95%CI: 1.00, 1.12), P=0.033] and by 17% in East Asia [HR=1.17 (95%CI: 1.02, 1.33), P=0.020]. However, the effect was not statistically significant in Europe. PD risk exhibited a 7% rise [HR=1.07 (95%CI: 1.02, 1.14), P=0.011] in individuals aged 60 years and older, which was different from that in individuals younger than 60 years. Exposure to various concentrations of PM2.5 was observed to associate with an elevated risk of PD. The inclusion of adjustments for PD-related comorbidities did not alter the conclusion that ambient PM2.5 exposure might elevate the risk of PD. The studies with a follow-up duration exceeding 5 years and reporting more than 1000 PD cases suggested a significant increase in the risk of PD due to ambient PM2.5 exposure [HR=1.06 (95%CI: 1.01, 1.12), P=0.012; HR=1.06 (95%CI: 1.01, 1.11), P=0.027, respectively]. Conversely, no significant association was identified between ambient PM2.5 exposure and the risk of PD within the cohorts with a follow-up duration of less than 5 years and reporting fewer than 1000 PD cases [HR=1.09 (95%CI: 0.95, 1.26), P=0.214; HR=1.12 (95%CI: 0.98, 1.02), P=0.092, respectively]. The sensitivity analysis showed that the results were stable. The publication bias analysis and the combined trim-and-fill method showed that the results were robust. Conclusion The risk of PD could be increased by ambient PM2.5 exposure and influenced by age and area. The research results might be affected by the duration of follow-up and the quantity of PD cases reported.
ABSTRACT
【Objective】 To explore the perioperative blood management in patients with pancreatic pseudocyst combiend with coagulation factor Ⅴ(FⅤ) deficiency. 【Methods】 Preoperative: In order to determine the effect of cryoprecipitated antihemophilic factor and fresh frozen plasma (FFP) on the elevation level of factor Ⅴ, we alternately infused cryoprecipitate and FFP in the resting state. TEG, coagulation function and coagulation factor activity were monitored before and 1 h, 24 h and 48 h after infusion, and intraoperative and postoperative blood transfusion strategies were formulated. FFP 600 mL and cryoprecipitate 10 U were supplemented preoperatively. Intraoperative: The operation procedure was performed for 7 hours with an infusion of 600 mL FFP without significant bleeding. Postoperative: FFP was infused. 【Results】 Preoperative: The coagulation factor Ⅴ activity on pre-operation was 1.9% and 1.8%. After alternating infusion cryoprecipitate 10 U and FFP 1 200 mL, the FⅤactivity increased to 5.1% and 6.0%, respectively. There was no significant difference in TEG parameters, PT and ATPP results were decreased to varying degrees. Intraoperative: The operation was successful without obvious bleeding. Postoperative: FFP 500 mL was infused 2 h after operation, and FFP 250-500 mL was injected daily from 1 to 7 days after surgery. No significant bleeding was observed in the wound, the results of TEG, PT, APTT and hemoglobin (Hb) did not change significantly compared with those before surgery. The patient was discharged successfully 12 days after surgery. The genetic test results showed that he had inherited coagulation factor Ⅴ deficiency, which was a compound heterozygous variation. 【Conclusion】 Perioperative blood management in patients with FⅤ deficiency combined with surgical disease, requiring pre-transfusion evaluation and post-transfusion evaluation in combination with laboratory investigations and clinical manifestations, cryoprecipitate and fresh frozen plasma can be effective in supplementing coagulation factors. The TEG seems to be better than the Seven items of coagulation function in judging the clotting status of patients with FⅤ deficiency.
ABSTRACT
Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.
ABSTRACT
Autologous ozonized blood transfusion (AOBT) is a therapeutic method that mixes blood with medical ozone in vitro and then reinfuses it into the body. It has been widely used in the auxiliary treatment of ischemia, hypoxia, autoimmune diseases and cancer. The mechanism of ozone therapy is still unclear, and no unified standard for the concentration, frequency and course of AOBT treatment has been established. This article aims to review the mechanism and clinical application of AOBT.
ABSTRACT
ObjectiveTo analyze the distribution of traditional Chinese medicine （TCM） patterns as well as factors related to acute exacerbation in group E of chronic obstructive pulmonary disease （COPD）. MethodsThe general data of 161 COPD patients， including gender， age， body mass index （BMI）， disease course， smoking history， and past history， were collected. In terms of the four examinations of TCM， the differentiated patterns included phlegm-heat obstructing the lung， turbid phlegm obstructing the lung， phlegm stasis obstructing the lung， lung-spleen qi deficiency， and lung-kidney deficiency. The modified British Medical Research Council （mMRC） scale and COPD assessment test （CAT）， the pulmonary function indicators including forced expiratory volume in the first second （FEV1） and ratio of forced expiratory volume to forced vital capacity at second 1 （FEV1/FVC）， GOLD grade， and the patient's acute exacerbations in the previous year were recorded. Multivariate regression analysis was performed using logistic regression model to determine the relevant factors of patients in COPD group E. The distribution of acute exacerbations in different TCM symptom patients in group E was analyzed. ResultsThere were 80 patients （49.69%） in group E and 81 patients （50.31%） in non-group E. In group E， 23 （28.75%） patients had a history of two acute exacerbations， while 35 （43.75%） had three acute exacerbations， and 22 （27.5%） had more than three acute exacerbations. There were 13 （16.25%） cases of phlegm-heat obstructing the lung pattern， 6 （7.5%） cases of turbid phlegm obstructing the lung pattern， 8 （10%） cases of phlegm stasis obstructing the lung pattern， 22 cases （27.5%） of lung-spleen qi deficiency pattern， and 31 （38.75%） cases of lung-kidney deficiency pattern. There were significant differences in smoking history， disease course， TCM pattern， TCM syndrome score， mMRC score， and CAT score between groups （P＜0.05）. A total of 107 of the 161 patients completed pulmonary function tests， and the differences in FEV1， FEV1/FVC and GOLD grades between groups were statistically significant （P＜0.05）. Multivariate regression analysis showed that TCM pattern， TCM syndrome score and CAT score were statistically significant factors for COPD patients in group E （P＜0.05）. There were statistically significant differences in the number of acute exacerbations in different TCM patterns in group E （P＜0.05）. The patients with two acute exacerbations in the past year were mainly phlegm-heat obstructing the lung and lung-spleen qi deficiency patterns， while the three acute exacerbations were mainly seen in lung-spleen qi deficiency and lung-kidney deficiency patterns， and more than three exacerbations were more common with lung -kidney deficiency pattern. ConclusionsPatients in COPD group E were mainly the lung-spleen qi deficiency and lung-kidney deficiency patterns. Deficiency of healthy qi is the main reason for the increase in the number of acute exacerbations， and TCM patterns and CAT score were the main related factors.
ABSTRACT
Objective:To investigate the efficacy of two-way needle suture technique (TNST) in the minimally invasive repair of acute closed Achilles tendon rupture.Methods:From June 2019 to June 2021, 26 patients with acute closed Achilles tendon rupture were treated at Zhengzhou Orthopedic Hospital. They were 20 males and 6 females, with a mean age of 28 (23, 31) years. The rupture end was (4.2±1.3) cm away from the calcaneal insertion, and the interval from injury to operation 4.3 (2.0, 5.0) d. Preoperative MRI examinations revealed in all the patients closed Achilles tendon rupture which was to be repaired by TNST. The operation time, incision length, incidence of complications, ankle dorsiflexion and plantar flexion were recorded. The Arner-Lindholm scoring was used to evaluate the clinical efficacy.Results:The operation time was (20.0±5.0) min and the incision length (2.5±0.4) cm. Postoperatively, all incisions healed by the first stage, with no complications like incision infection, skin edge necrosis, deep vein thrombosis at lower limbs, injury to the sural nerve, or re-rupture of the Achilles tendon. All patients were followed up for (12.0±6.0) months. At the last follow-up, the patients walked normally, their incisions healed well, the continuity of the Achilles tendon was good by palpation, their heel lift was strong, and all their activities were restored to the levels before rupture of the Achilles tendon. The ankle dorsiflexion was 22.6°±3.7° and the plantar flexion 25.3°±3.7°, According to the Arner-Lindholm evaluation, the clinical efficacy was rated as excellent in 25 cases and as good in 1 case, giving an excellent and good rate of 100% (26/26).Conclusion:In the minimally invasive repair of acute closed Achilles tendon rupture, TNST shows the advantages of limited surgical invasion, a low incidence of postoperative complications, and reliable curative effects.

ABSTRACT
Granulocyte is granular leukocytes in blood, which play an important role in anti-infection treatment and cancer-killing activity. In clinical, allogeneic granulocyte transfusion can be applied for anti-infection treatment when the patients are seriously infected but the antibiotic treatment is ineffective, especially the WBC counts are extremely low. Recently, some progress has been made in the researches about treating cancer with granulocyte infusion. It is possible to use allogeneic granulocyte infusion with high killing activity to treat the certain types of cancers.
ABSTRACT
【Objective】 To investigate the clinical efficacy and safety of centrifugal plasma separation combined with plasma adsorption in the treatment of hypertriglyceridemia. 【Methods】 The data of 42 patients with hypertriglyceridemia from February 2019 to October 2020 were retrospectively collected and analyzed. The patients were treated with plasma component exchange by centrifugal plasma separation combined with plasma adsorption (PA) lipid-lowering therapy. The plasma was separated by an automatic blood cell separator, and was then adsorbed by membrane plasma component absorber. Conditions for plasma component exchange were sodium citrate as anticoagulant, the whole blood flow rate at (30~80) mL/min, the plasma circulation volume 2 500 mL, the treatment time 2 h, and the discarded plasma 200 mL. The treatment was performed once every two weeks, twice in total, and the efficacy was evaluated 6 weeks later. The changes of serum total protein (TP), blood lipid indexes and hemorheology indexes before and after treatment were observed, and the adverse reactions during treatment were recorded. 【Results】 The effective rate of 42 patients after treatment was 95.24%. The values of TP, TC, TG and LDL-C decreased significantly (82.53±6.37 vs 74.26±5.91, 7.46±1.83 vs 3.88±1.06, 5.91±2.16 vs 2.20±1.13, 4.23±1.02 vs 3.17±0.85) while HDL-C increased significantly(0.92±0.15 vs 1.23±0.26) after the treatment (P<0.05). After the treatment, the levels of whole blood high-cut viscosity, whole blood low-cut viscosity, plasma viscosity, hematocrit and fibrinogen decreased significantly (7.53±1.21 vs 5.16±0.88, 18.27±3.15 vs 12.04±2.32, 2.46±0.37 vs 1.68±0.29, 52.24±5.31 vs 32.53±4.42, 4.28±0.76 vs 3.14±0.45)(P<0.05). The incidence of adverse reactions was 14.3%, and no serious adverse reactions were observed. 【Conclusion】 The centrifugal plasma separation combined with plasma adsorption in the treatment of hypertriglyceridemia is safe and effective.

ABSTRACT
Objective:To summarize and analyze the clinical data of Chinese patients with colony-stimulating factor 1 receptor (CSF1R)-related leukoencephalopathy, and clarify the phenotypic and genetic characteristics of Chinese patients.Methods:Medical history of patients with CSF1R-related leukoencephalopathy diagnosed from April 1, 2018 to January 31, 2021 in the department of neurology of 22 hospitals in China was collected, and scores of Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment Scale (MoCA), magnetic resonance severity scale were evaluated. Group comparison was performed between male and female patients.Results:A total of 62 patients were included, and the male-female ratio was 1∶1.95. The age of onset was (40.35±8.42) years. Cognitive impairment (82.3%, 51/62) and motor symptoms (77.4%,48/62) were the most common symptoms. The MMSE and MoCA scores were 18.79±7.16 and 13.96±7.23, respectively, and the scores of two scales in male patients (22.06±5.31 and 18.08±5.60) were significantly higher than those in females (15.53±7.41 , t=2.954, P=0.006; 10.15±6.26, t=3.328 , P=0.003). The most common radiographic feature was bilateral asymmetric white matter changes (100.0%), and the magnetic resonance imaging severity scale score was 27.42±11.40, while the white matter lesion score of females (22.94±8.39) was significantly higher than that of males (17.62±8.74 , t=-2.221, P<0.05). A total of 36 CSF1R gene mutations were found in this study, among which c.2381T>C/p.I794T was the hotspot mutation that carried by 17.9% (10/56) of the probands. Conclusions:The core phenotypic characteristics of CSF1R-related leukoencephalopathy in China are progressive motor and cognitive impairment, with bilateral asymmetrical white matter changes. In addition, there exist gender differences clinically, with severer cognitive impairment and imaging changes in female patients. Thirty-six CSF1R gene mutations were found in this study, and c.2381T>C/p. I794T was the hotspot mutation.
ABSTRACT
Objective:To evaluate the quantitative diagnostic value of controlled attenuation parameter (CAP) in health checkup groups with asymptomatic nonalcoholic fatty liver disease.Methods:A multicenter prospective study was conducted among Chinese individuals undergoing regular health checkups; a total of 173 subjects were investigated. Human body indexes such as height, weight, and blood pressure were measured, and complete blood count, liver function, blood lipid, FibroScan, and MRI-PDFF examinations were performed. Correlation between MRI-PDFF and CAP was described using Spearman′s and Pearson′s coefficients. Diagnostic efficacy of the CAP was evaluated using the subject work characteristic curve and the area under this curve, and the optimal cut-off value was determined according to the Youden index.Results:The average age and body mass index of the subjects were 45.0±10.5 years and 25.8±4.0 kg/m 2, respectively. A linear correlation was found between CAP and lg transformed magnetic resonance imaging-based proton density fat fraction results (Pearson′s coefficient 0.772, P<0.001). When optimized for ≥90% sensitivity, the CAP cutoff for staging ≥S1 steatosis was 244 dB/m. Conclusions:The CAP result was significantly correlated with the liver fat fraction measured by MRI-PDFF, and capable of differentiating steatosis grades. CAP can be used as a tool for screening fatty liver in health checkup groups.
ABSTRACT
Objective@#To investigate the value of statistical parametric mapping (SPM) analysis of 18F-fluorodeoxyglucose (FDG) PET imaging in the differential diagnosis of Parkinsonism in single-case level.@*Methods@#SPM software was used to retrospectively analyze the 18F-FDG PET images of 160 patients (104 males, 56 females, age: 30-82 years) who were suspected with Parkinsonism at baseline and were clinical confirmed by follow-up from April 2010 to December 2017. 18F-FDG PET images of patients was compared with those of age-matched healthy controls in single-case level using two-sample t test in SPM software to obtain the imaging diagnosis. By comparing imaging diagnosis with the final clinical diagnosis, the diagnostic accuracy of SPM in the overall cohort as well as the early subcohort (duration of disease less than 2 years (56 males, 22 females, age: 50-82 years)) were calculated respectively.@*Results@#Among 160 patients with Parkinsonism, 146(91.2%) had the same 18F-FDG PET diagnosis as their final clinical diagnosis. The diagnostic sensitivity for Parkinson′s disease (PD), multiple system atrophy (MSA), progressive supranuclear palsy (PSP) and cortical basal ganglia degeneration (CBD) were 93.5%(86/92), 92.3%(24/26), 84.0%(21/25) and 15/17, respectively. The specificity were 95.6%(65/68), 95.5%(128/134), 96.3%(130/135) and 100%(143/143), respectively. In the early subcohort, the analysis also achieved similar differential diagnosis effectiveness(92.3%).@*Conclusion@#The single-case 18F-FDG PET imaging SPM analysis can be helpful in the early differential diagnosis of Parkinsonism effectively.

OBJECTIVE@#To analyze the current status of diagnosis and management of acute appendicitis (AA) in China.@*METHODS@#Questionnaire survey was used to retrospectively collect data of hospitalized patients with AA from 43 medical centers nationwide in 2017 (Sort by number of cases provided: Jinling Hospital of Medical School of Nanjing University, The First Affiliated Hospital of Xinjiang Medical University, Lu'an People's Hospital, Tengzhou Central People's Hospital, Dalian Central Hospital, The Affiliated Hospital of Xuzhou Medical University, Dongying People's Hospital, Jinjiang Hospital of Traditional Chinese Medicine, Huangshan Shoukang Hospital, Xuyi People's Hospital, Nanjing Jiangbei People's Hospital, Lanzhou 940th Hospital of PLA, Heze Municipal Hospital, The First College of Clinical Medical Science of China Three Gorges University, Affiliated Jiujiang Hospital of Nanchang University, The Second People's Hospital of Hefei, Affiliated Central Hospital of Shandong Zaozhuang Mining Group, The Third People's Hospital of Kunshan City, Xuzhou First People's Hospital, The 81st Group Army Hospital of PLA, Linyi Central Hospital, The General Hospital of Huainan Eastern Hospital Group, The 908th Hospital of PLA, Liyang People's Hospital, The 901th Hospital of Joint Logistic Support Force, The Third Affiliated Hospital of Chongqing Medical University, The Fourth Hospital of Jilin University, Harbin Acheng District People's Hospital, The First Affiliated Hospital of Zhengzhou University, Nanjing Luhe People's Hospital, Taixing Municipal People's Hospital, Baotou Central Hospital, The Affiliated Hospital of Nantong University, Linyi People's Hospital, The 72st Group Army Hospital of PLA, Zaozhuang Municipal Hospital, People's Hospital of Dayu County, Taixing City Hospital of Traditional Chinese Medicine, Suzhou Municipal Hospital, Beijing Guang'anmen Hospital, Langxi County Hospital of Traditional Chinese Medicine, Nanyang Central Hospital, The Affiliated People's Hospital of Inner Mongolia Medical University).The diagnosis and management of AA were analyzed through unified summary. Different centers collected and summarized their data in 2017 and sent back the questionnaires for summary.@*RESULTS@#A total of 8 766 AA patients were enrolled from 43 medical centers, including 4 711 males (53.7%) with median age of 39 years and 958 (10.9%) patients over 65 years old. Of 8 776 patients, 5 677 cases (64.6%) received one or more imaging examinations, and the other 3 099 (35.4%) did not receive any imaging examination. A total of 1 858 (21.2%) cases received medical treatment, mainly a combination of nitroimidazoles (1 107 cases, 59.8%) doublet regimen, followed by a single-agent regimen of non-nitroimidazoles (451 cases, 24.4%), a nitroimidazole-free doublet regimen (134 cases, 7.2%), a triple regimen of combined nitroimidazoles (116 cases, 6.3%), nitroimidazole alone (39 cases, 2.1%) and nitroimidazole-free triple regimen (3 cases, 0.2%). Of the 6 908 patients (78.8%) who underwent surgery, 4 319 (62.5%) underwent laparoscopic appendectomy and 2589 (37.5%) underwent open surgery. Ratio of laparotomy was higher in those patients under 16 years old (392 cases) or over 65 years old (258 cases) [15.1%(392/2 589) and 10.0%(258/2 589), respectively, compared with 8.5%(367/4 316) and 8.0%(347/4 316) in the same age group for laparoscopic surgery, χ²=91.415, P<0.001; χ²=15.915,P<0.001]. Patients with complicated appendicitis had higher ratio of undergoing open surgery as compared to those undergoing laparoscopic surgery [26.7%(692/2 589) vs. 15.6%(672/4 316), χ²=125.726, P<0.001].The cure rates of laparoscopic and open surgery were 100.0% and 99.8%(2 585/2 589) respectively without significant difference (P=0.206). Postoperative complication rates were 4.5%(121/2 589) and 4.7%(196/4 316) respectively, and the difference was not statistically significant (χ²=0.065, P=0.799). The incidence of surgical site infection was lower (0.6% vs. 1.7%, χ²=17.315, P<0.001), and hospital stay was shorter [6(4-7) days vs. 6(5-8) days, U=4 384 348.0, P<0.001] in the laparoscopic surgery group, while hospitalization cost was higher (median 12 527 yuan vs. 9 342 yuan, U=2 586 809.0, P<0.001).@*CONCLUSIONS@#The diagnosis of acute appendicitis is still clinically based, supplemented by imaging examination. Appendectomy is still the most effective treatment at present. Laparoscopic appendectomy has become the main treatment strategy, but anti-infective drugs are also very effective.
