ABSTRACT

Objective To explore the epidemiology of human papillomavirus infection in women of childbearing age in Shaanxi Province. Methods A stratified random sampling method was used to select 16705 patients under childbearing age in Shaanxi from January 2015 to January 2020, and 857 healthy patients who had physical examination during the same period were selected as the control group. The general information of patients was obtained through questionnaire survey, and the risk factors were analyzed by single factor and multivariate logistic analysis. Results The detection rate of human papillomavirus infection in 16705 cases was 2570 (15.38%), of which 1972 cases of high-risk type (11.80%) were higher than 598 cases (3.58%) of low-risk type (χ2: 795.77, P 2: 259.08, P <0.001).The proportions of younger than 30 years old, sexual life ≥3 times/week, no condoms, cervical erosion, and smoking were higher in high-risk human papillomavirus infection group than the control group (P<0.05). After multivariate logistic regression analysis, the results showed that the frequency of sexual life and the greater degree of cervical erosion were independent risk factors for high-risk human papillomavirus infection [OR (95% CI): 3.112 (1.607~7.702), 4.209 (2.338~ 12.526, P<0.05], the use of condoms is a high-risk protective factor for human papillomavirus infection [OR(95%CI): 0.674 (0.578~0.699, P<0.05]) Conclusion The frequency of sexual life and the degree of cervical erosion are high in women of childbearing age in Shaanxi. The use of condoms can effectively prevent human papillomavirus infection. Reasonably formulating effective intervention measures and vigorously publicizing the knowledge of human papillomavirus prevention and treatment is the key to reducing human papillomavirus infection in women of childbearing age in Shaanxi.

ABSTRACT

Objective To evaluate the conversion of serum antibodies against Schistosoma japonicum in humans and livestock detected by immunological tests following treatment with praziquantel. Methods The studies pertaining to serological tests of schistosomiasis japonica published from 1991 to 2020 were retrieved in electronic databases, including Chinese National Knowledge Infrastructure, WanFang Data, PubMed and ScienceDirect. Data were extracted from included studies. The publication bias was assessed with funnel plots using the software RevMan version 5.3, and the conversion of antibodies against S. japonicum was evaluated through meta-analysis. Results A total of 40 publications were included in the final meta-analysis, consisting of 33 Chinese publications and 7 English publications, and all immunological tests were performed with indirect hemagglutination test (IHA) and enzyme-linked immunosorbent assay (ELISA). Pooled analysis showed that the negative rates of serum anti-S. japonicum antibody were 45.36% [95% confidential interval (CI): (43.96%, 46.76%)] and 20.83% [95% CI: (19.69%, 21.97%)] detected by ELISA and IHA within 6 months post praziquantel treatment, 62.95% [95% CI: (61.59%, 64.31%)] and 55.61% [95% CI: (54.21%, 57.01%)] within 6 to 12 months after treatment and 85.92% [95% CI: (84.94%, 86.90%)] and 86.90% [95% CI: (85.95%, 87.85%)] over 12 months after treatment, respectively. Conclusions The negative rate of the serum anti-S. japonicum antibody by IHA and ELISA increased with the time of post-treatment with praziquantel. The overall negative rates of anti-S. japonicum antibody detected by IHA and ELISA are low within 12 months post praziquantel treatment. However, a high negative rate of anti-S. japonicum antibody is detected if there is no new contact with infested water after 12 months of praziquantel treatment.

ABSTRACT

Objective To analyze the monitoring data of Oncomelania hupensis in the national schistosomiasis surveillance sites of China from 2015 to 2019, so as to understand the changes of Oncomelania snail status in the schistosomiasis-endemic areas of China and to provide the scientific evidence for Oncomelania snail control. Methods According to the requirements of National Scheme for Schistosomiasis Surveillance in China (2014 Edition), national schistosomiasis surveillance sites were assigned in all schistosomiasis-endemic counties (cities, districts) and the potential endemic counties (cities, districts) in the Three Gorges Reservoir areas, and Oncomelania snail status was monitored according to different epidemic types. In endemic areas, Oncomelania snail survey was performed by means of systematic sampling and environmental sampling, and the occurrence of frames with Oncomelania snails and the prevalence of Schistosoma japonicum infections in Oncomelania snails were calculated, while in potential endemic areas, the risk of imported Oncomelania snails and Oncomelania snails in floating debris were monitored. Results Oncomelania snail survey was performed covering an area of 116 834.16 hm2 in the national schistosomiasis surveillance of China from 2015 to 2019, with 35 007.62 hm2 Oncomelania snail habitats identified. A total of 6 908 292 frames were surveyed during the 5-year period, and there were 364 555 frames detected with Oncomelania snails, with a 5.28% mean occurrence of frames with Oncomelania snails. Among 997 508 living Oncomelania snails captured, no S. japonicum infections were detected, and loop-mediated isothermal amplification (LAMP) assay detected 18 positive mixed Oncomelania snail samples. During the period from 2015 to 2019, 147.20 hm2 emerging Oncomelania snail habitats were identified, with an overall tendency towards a rise seen in the proportion of emerging Oncomelania snail habitats in plain regions with waterway networks (0.12% to 92.00%), a tendency towards a rise followed by decline seen in marshland and lake regions (0 to 96.72%), and a large fluctuation in hilly regions (0 to 88.49%). A total of 831.10 hm2 re-emerging Oncomelania snail habitats were found in the national schistosomiasis surveillance sites of China from 2015 to 2019, with an overall tendency towards a rise seen in the proportion of re-emerging Oncomelania snail habitats in marshland and lake regions (16.05% to 79.66%), an overall tendency towards a decline seen in hilly regions (19.25% to 81.00%), and a minor fluctuation in plain regions with waterway networks (1.10% to 10.14%). During the 5-year period from 2015 to 2019, a total of 48 656 kg floating debris were captured in 4 surveillance sites in the Three Gorges Reservoir areas, and 2 204 snails were found, with no Oncomelania snails identified. Conclusions The areas of Oncomelania snail habitats tended to be stable in the national schistosomiasis surveillance sites of China during the period from 2015 to 2019, however, there was a gradual rise in the area of Oncomelania snail habitats year by year, and LAMP assay identified positive Oncomelania snail samples, suggesting Oncomelania snail control is far from optimistic in China.

ABSTRACT

Objective To understand the morbidity due to Schistosoma japonicum in national schistosomiasis surveillance sites of China from 2015 to 2019, so as to provide insights into schistosomiasis control and elimination and provide the scientific evidence for formulating the new scheme for schistosomiasis surveillance in China. Methods According to the requirements of National Scheme for Schistosomiasis Surveillance in China (2014 Edition), national schistosomiasis surveillance sites were assigned in all schistosomiasis-endemic counties (cities, districts) and the potential endemic counties (cities, districts) in the Three Gorges Reservoir areas, and S. japonicum infections were monitored in local residents, mobile populations and livestock according to different epidemic types. The sero-prevalence of S. japonicum infections, adjusted prevalence of human S. japonicum infections, characteristics of egg-positive individuals and prevalence of S. japonicum infections livestock were analyzed. Results S. japonicum infections were monitored in 453 schistosomiasis-endemic counties (cities, districts) from 13 provinces (municipalities, autonomous regions) and 4 potential endemic counties (cities, districts) from the Three Gorges Reservoir areas in China from 2015 to 2019. During the 5-year period from 2015 to 2019, the sero-prevalence of S. japonicum infections reduced from 3.35% to 1.63% among local residents and from 1.15% to 0.75% among mobile populations, while the adjusted prevalence of infections reduced from 0.05% to 0 among local residents and from 0.20% to 0.001 03% among mobile populations. There were significant differences in the sero-prevalence of S. japonicum infections among local residents and mobile populations in terms of province, occupation and age (all P values < 0.05). A total of 132 egg-positives were identified during the 5-year period, including 97 local residents (inter-quartile range for ages, 47 to 61 years), and 35 mobile populations (inter-quartile range for ages, 26 to 48 years), and there was a significant difference in the age distribution between local residents and mobile populations (P < 0.05). There were totally 6 bovines (5 in 2015 and 1 in 2016) identified with S. japonicum infections in national schistosomiasis surveillance sites of China, with no S. japonicum infections detected in bovines from 2017 to 2019. Conclusions The prevalence of schistosomiasis is very low in China. Further surveillance including more mobile surveillance sites seems justified to identify the risk of schistosomiasis as soon as possible and interrupt the transmission route, so as to facilitate the elimination of schistosomiasis in China.

ABSTRACT

Since 2015 when the transmission of schistosomiasis was controlled in China, the country has been moving towards elimination of schistosomiasis, with the surveillance-response as the main interventions for schistosomiasis control. During the period of the 13th Five-Year Plan, the transmission of schistosomiasis had been interrupted in four provinces of Sichuan, Jiangsu, Yunnan and Hubei and the prevalence of schistosomiasis has been at the historically lowest level in China. As a consequence, the goal set in The 13th Five-Year National Schistosomiasis Control Program in China is almost achieved. However, there are multiple challenges during the stage moving towards elimination of schistosomiasis in China, including the widespread distribution of intermediate host snails and complicated snail habitats, many types of sources of Schistosoma japonicum infections and difficulty in management of bovines and sheep, unmet requirements for the current schistosomiasis control program with the currently available tools, and vulnerable control achievements. During the 14th Five-Year period, it is crucial to consolidate the schistosomiasis control achievements and gradually solve the above difficulties, and critical to provide the basis for achieving the ultimate goal of elimination of schistosomiasis in China. Based on the past experiences from the national schistosomiasis control program and the challenges for schistosomiasis elimination in China, an expert consensus has been reached pertaining to the objectives, control strategy and measures for The 14th Five-Year National Schistosomiasis Control Program in China, so as to provide insights in to the development of The 14th Five-Year National Schistosomiasis Control Program in China.

ABSTRACT

Schistosomiasis was once endemic in 12 provinces (municipalities, autonomous regions) along and south of the Yangtze River basin, which seriously damages human health and hinders socioeconomic developments in China. Following the concerted efforts for 70 years, remarkable achievements have been gained in the national schistosomiasis control program of China. However, there are still multiple challenges for elimination of schistosomiasis in the country. This paper describes the current status of schistosomiasis and the challenges during the progress towards the elimination of schistosomiasis, and proposes the goals, key points and research priorities of schistosomiasis control in China during the 14th Five-Year Plan Period.

ABSTRACT

Objective:To investigate the molecular mechanism of the disease based on the clinical characterization and genetic mutation analysis in a family with intellectual disability.Methods:The proband with intellectual disability was diagnosed at Luohe Central Hospital in December 2019. Peripheral blood samples were collected from four family members. Whole exome sequencing (WES) was used to screen the pathological mutations. Then the PCR and Sanger sequencing were used to verify the selected mutations and combine the relevant database to analyze variation loci.Results:We infer that the ARX c.1162 A>G was co-segregated with the phenotype of the family based on the results of WES. The results of sanger sequencing and WES are consistent. The mother of the proband is the carrier of the mutation. There is no mutation frequency reported in the healthy population. The mutation of the ARX c.1162A>G is harmful inferred by a variety of bioinformatics software. Combined with the phenotypic analysis of OMIM database, we infer the phenotype caused by the mutation is consistent with the patients in the family.Conclusion:The mutation of the ARX c.1162 A>G may be the cause of the intellectual disability in the family affected. And the variant has not been reported in China.

ABSTRACT

Objective:To investigate the clinical efficacy and prognosis of transjugular intrahepatic portosystemic shunt (TIPS) and drug combined with endoscopic treatment in patients with liver cirrhosis and esophagogastric variceal bleeding (EGVB).Methods:From January 2012 to December 2013, at the First Affiliated Hospital of Xi′an Jiaotong University, the data of 147 patients with liver cirrhosis and EGVB undergoing TIPS or drug combined with endoscopic treatment were retrospectively collected, with 87 cases in TIPS treatment group and 60 in drug combined with endoscopic treatment group.The 5 years follow-up data were analyzed, and the overall survival rates, rebleeding-free survival rates and hepatic encephalopathy-free survival rates at 6 weeks, 1 year, 2 years and 5 years after treatment of two groups were compared. Independent sample t test, Mann-Whitney U test, chi-square test, Fisher exact test, Z test, log-rank test and trend test were used for statistical analysis. Results:There were no significant differences in age, gender, etiology, Child-Pugh classification, initial liver function, coagulation function, liver ascites, previous history of hepatic encephalopathy, blood pressure and preoperative blood transfusion history between the TIPS treatment group and combination of drugs and endoscopy treatment group (all P>0.05). Forty-one patients died within 5 years, of which 20 (48.8%) died of rebleeding and 6 (14.6%) died of hepatic encephalopathy. There were no significant differences in 6-week, 1-year and 2-year overall survival rates between the TIPS group and drug combined with endoscopic treatment group (all P>0.05), however the 5-year overall survival rate of the TIPS treatment group was higher than that of the drug combined with endoscopic treatment group (78.4% vs. 63.2%), and the difference was statistically significant ( Z=2.06, P=0.048). The 6-week, 1-year, 2-year, 5-year rebleeding-free survival rates of the TIPS group were 97.7%, 96.5%, 88.9% and 70.9%, respectively, which were all higher than those of the drug combined with endoscopic treatment group (86.7%, 53.3%, 43.3% and 27.1%), and the differences were statistically significant ( Z=2.35, 6.39, 6.26 and 4.80, all P<0.05). There were no significant differences in hepatic encephalopathy-free survival rates at 6 weeks, 1 year and 2 years after treatment between the TIPS group and drug combined with endoscopic treatment group (all P>0.05), however the 5-year hepatic encephalopathy-free survival rate of the TIPS treatment group was lower than that of the drug combined with endoscopic treatment group (67.7% vs. 86.7%), and the difference was statistically significant ( Z=2.28, P=0.030). The lower the Child-Pugh classification, the higher the cumulative 5-year survival rate ( χ2=6.75, P<0.01). There was no statistically significant difference in the 5-year overall survival rate in patients with the same Child-Pugh classification between the TIPS group and the drug combined with endoscopic treatment group (all P>0.05). Conclusions:The efficacy of TIPS is better than that of the drug combined with endoscopic treatment in treating EGVB. Even the long-term risk of hepatic encephalopathy of TIPS is higher, the short-term, middle-term and long-term rebleeding rate are decreased. Patients with Child-Pugh grade C do not need to avoid TIPS when choosing the treatment, the earlier the TIPS used, the better survival benefit will be obtained.

ABSTRACT

Borderline personality disorder (BPD) is characterized by emotional regulation, interpersonal relationship, self-image and impulse control instability. It is a mental disorder with high morbidity, high mortality and difficult treatment. Psychotherapy is the main treatment for this disease. However, current mainstream psychotherapy, such as dialectical behavior therapy (DBT), has certain limitations, so it is necessary to find a more convenient and effective treatment method. Acceptance and commitment therapy (ACT), as the representative therapy of the third generation of cognitive therapy, aims to make individuals accept inevitable pain, find their own value and commit to action, and finally improve their psychological flexibility to live a meaningful life. ACT has been used in the treatment of a variety of mental disorders, and the effect is significant. By expounding the pathogenesis of BPD and the theoretical model of ACT, this paper analyzed the rationality and feasibility of ACT intervention in BPD from the pathological model and treatment model of ACT. Finally, the research results of ACT treating BPD in recent years were summarized. The results show that ACT provides a promising method for the treatment of BPD patients, however, more studies are needed to prove its use in this group and its specific mechanism.

ABSTRACT

Objective:To explore the effect of post-pyloric feeding by spiral nasoenteric tubes on the prognosis of critically ill patients with acute gastrointestinal injury (AGI) grade Ⅱ.Methods:A retrospective study was performed to analyze the clinical data of critically ill adult patients with AGI grade Ⅱ, who were enrolled in three randomized controlled trials conducted by Guangdong Provincial People's Hospital for post-pyloric tube placement between April 2012 and May 2019. Data including demographic characteristics, serological indicators of nutrition, the tube tip position confirmed by abdominal X-ray 24 h after tube insertion, and intensive care unit (ICU), 28-day and hospital mortality were collected. Patients were divided into the post-pyloric feeding group and gastric feeding group according to the tube tip position. Propensity score matching method was used to perform 1:1 matching, and the differences of each index between the two groups were compared after matching. Then the influencing factors of P<0.1 were included in multivariate logistic regression analysis to investigate the potential ICU mortality risk factors of critically ill patients with AGI gradeⅡ. Factors with 0.1 level of significance from the univariate analysis were considered in the multivariate analysis. Results:There were 90 patients in post-pyloric feeding group and 90 patients in the gastric feeding group. Demographics and clinical characteristics of study population were well balanced between the two groups after matching. ICU, 28-day and hospital mortality in the post-pyloric feeding group were significantly lower than those in the gastric feeding group (4.4% vs 15.6%, 14.4% vs 27.8%, 6.7% vs 17.8%, all P < 0.05). Multivariate logistic regression analysis indicated that post-pyloric feeding was an independent protective factor [odds ratio ( OR)=0.295, 95% confidence internal (95% CI): 0.091-0.959, P=0.042] and APACHEⅡ score was an independent risk factor ( OR=1.111, 95% CI: 1.025-1.203, P=0.010) for ICU mortality of critically ill patients with AGI gradeⅡ. Conclusions:Post-pyloric feeding for critically ill patients with AGI grade Ⅱ could decrease ICU mortality and is an independent protective factor against mortality.

ABSTRACT

Malaysia is a multi-ethnic and multi-cultural constitutional monarchy and federal system located in Southeast Asia. The top three diseases that cause deaths are ischemic heart disease, lower respiratory tract infections and stroke. Lower respiratory tract infections, colorectal cancer and Alzheimer’s disease have been the fastest growing diseases in recent years. The health insurance system complements public and private health care system. Traditional medicine in Malaysia includes Malaysian Medicine, Traditional Chinese Medicine (TCM), Indian Medicine, Islamic Medicine and homeopathy. Although TCM, such as acupuncture, has not been covered by health insurance, it is widely used under the impetus of the local Chinese people. At present, in Malaysia, the TCM public acceptance and education need promotion, and scientific researches need to be improved. It is hoped that in the future, the development of TCM in Malaysia will be better developed and disseminated by promoting TCM relevant legislation, increasing public awareness, focusing on education and training, and carrying out international scientific research cooperation.

ABSTRACT

Due to the relative shortage of health resources, rational allocation and utilization of health resources is critical to achieving the maximum economic benefits in developing countries, which requires a health economic assessment to meet the needs to balance the competitive requirements of cost reduction and effectiveness enhancement. This review describes the advances in applications of health economic assessment techniques in four major infectious diseases, including AIDS, tuberculosis, hepatitis B and schistosomiasis. Currently, there is no standard economic assessment in the prevention and control of infectious diseases, and notably, the transparency of cost research is limited, which may affect the popularization of the study conclusions. Further health economic assessments of infectious diseases are required to improve the quality, standard and transparency of the economic evaluation through formulating strategies, to improve the standardization of studies, to improve the popularization of the study conclusions and to improve the applicability of the economic evaluation for policies.

ABSTRACT

Objective To investigate the epidemiological characteristics of current advanced schistosomiasis cases in China, so as to provide the scientific evidence for the precision management and medical care of advanced schistosomiasis. Methods The baseline data pertaining to the current advanced schistosomiasis cases in China were collected from the Epidemiological Dynamic Data Collection Platform (EDDC) operated by the Chinese Center for Disease Control and Prevention. The demographic characteristics, population and regional distribution and medical care of advanced schistosomiasis cases were analyzed with a descriptive method. Results A total of 31 889 cases with advanced schistosomiasis were reported in China by the end of June, 2019, and these cases were mainly identified in Hubei Province (7 737 cases) followed by in Jiangxi Province (7 256 cases), Hunan Province (5 615 cases), Anhui Province (5 236 cases) and Jiangsu Province (2 908 cases), accounting for 90.2% (28 752/31 889) of total cases in China. The current advanced schistosomiasis cases had a male/female ratio of 1.5∶1, and a mean age of (67.0 ± 11.2) years, with 92.6% (29 521/31 889) detected in individuals at ages of over 50 years. There were 97.6% (31 109/31 889) of the cases with an educational level of junior high school and lower, and 95.2% (30 359/31 889) with an occupation of farmers. Ascites (72.6%, 23 164/31 889) and splenomegaly types (26.3%, 8 386/31 889) were predominant in current advanced schistosomiasis cases in China, and there was a significant difference in the constituent ratio of disease types among current advanced schistosomiasis cases with different age groups (χ2 = 362.31, P < 0.01), with the ascites type as the predominant type of advanced schistosomiasis. Among the current advanced schistosomiasis cases, 88.9% (28 358/31 889) and 18.7% (5 973/31 889) had received medical treatment and surgical treatment, respectively. Conclusions The current advanced schistosomiasis cases are predominantly reported in five marshland and lake endemic provinces of China where schistosomiasis is not eliminated, and are mostly categorized as the ascites and megalosplenia types, with minor differences seen in gender and disease-type distributions. Precision medical care should be reinforced according to the epidemiological features of the current advanced schistosomiasis cases, and early screening and standard management and follow-up is required.

ABSTRACT

This report presented the endemic status of schistosomiasis in the People’s Republic of China at a national level in 2020, and analyzed the data collected from the national schistosomiasis prevention and control system and national schistosomiasis surveillance sites. Among the 12 provinces (municipality and autonomous region) endemic for schistosomiasis in China, Shanghai Municipality, Zhejiang Province, Fujian Province, Guangdong Province and Guangxi Zhuang Autonomous Region continued to consolidate the achievements of schistosomiasis elimination, and Sichuan and Jiangsu provinces maintained the criteria of transmission interruption, while Yunnan, Hubei, Anhui, Jiangxi and Hunan provinces maintained the criteria of transmission control by the end of 2020. A total of 450 counties (cites, districts) were found to be endemic for schistosomiasis in China, with 28 376 endemic villages covering 71 370 400 people at risk of infections. Among the 450 endemic counties (cities, districts), 74.89% (337/450), 21.87% (98/450) and 3.33% (15/450) achieved the criteria of elimination, transmission interruption and transmission control of schistosomiasis, respectively. By the end of 2020, 29 517 cases with advanced schistosomiasis were documented in China. In 2020, 11 117 655 individuals received inquiry examinations and 1 798 580 were positive; 5 263 082 individuals received serological tests and 83 179 were sero-positive. A total of 273 712 individuals received stool examinations and 3 were positive, including one case of acute schistosomiasis. In 2020, snail survey was performed in 19 733 endemic villages in China and Oncomelania snails were found in 7 309 villages, accounting for 37.04% of all surveyed villages, with 15 villages identified with emerging snail habitats. Snail survey covered an area of 736 984.13 hm2 and 206 125.22 hm2 snail habitats were found, including 1 174.67 hm2 emerging snail habitats and 1.96 hm2 habitats with infected snails. In 2020, 544 424 bovines were raised in the schistosomiasis-endemic areas of China, and 147 887 received serological examinations, with 326 positives detected, while 130 673 bovines received stool examinations, with no positives identified. In 2020, there were 19 214 patients with schistosomiasis receiving praziquantel chemotherapy, and 964 103 person-time individuals and 266 280 herd-time bovines were given expanded chemotherapy. In 2020, molluscicide treatment was performed in 136 141.92 hm2 snail habitats, and the actual area of chemical treatment was 71 980.22 hm2, while environmental improvements were performed in snail habitats covering an area of 1 464.03 hm2. Data from the national schistosomiasis surveillance sites of China showed that the mean prevalence of Schistosoma japonicum infections were both zero in humans and bovines in 2020, and no S. japonicum infection was detected in snails. The results demonstrate that the overall endemic status of schistosomiasis remains at a low level in China and the goal of the National Thirteenth Five-Year Plan for Schistosomiasis Control was achieved as scheduled; however, the endemic situation of schistosomiasis rebounded in local areas. Precision schistosomiasis control and intensified monitoring of the endemic situation and transmission risk of schistosomiasis are required to be performed to facilitate the progress towards elimination of schistosomiasis steadily.

ABSTRACT

The de Winter electrocardiogram pattern is an acute ST-segment elevation myocardial infarction equivalent, however this specific electrocardiogram change is easily ignored by clinicians. The de Winter electrocardiogram pattern in patients with acute chest pain mostly indicates sub-complete or complete occlusion of the left anterior descending or the diagonal branch. Patients with acute chest pain and such electrocardiographic finding should undergo emergency coronary angiography immediately to determine the coronary condition, and reperfusion therapy should be performed as soon as possible to reduce the incidence of adverse cardiovascular events.

ABSTRACT

BACKGROUND@#Lobectomy is the main treatment strategy for early lung cancer. However, there are many anatomical variations in the lungs, especially some pulmonary veins will deviate from the normal position, and even cross the border of lob to enter the adjacent lobes, which increases the difficulty and risk of lobectomy. This study aims to analyze the variation types and frequency of pulmonary translobar veins, and further investigate its clinical significance in lobectomy.@*METHODS@#This study retrospectively included 916 patients who underwent lung resection in our center from December 2018 to November 2019, and selected 310 patients who underwent enhanced chest computed tomography (CT) examination before surgery. Enhanced chest CT and three-dimensional computed tomography bronchography and angiography (3D-CTBA) of these patients were applied to analyze the types and frequency of translobar veins. Further, 48 cases of lobectomy whose operation areas involved translobar veins were further screened out of 916 surgical cases (Among them, the translobar veins of 36 subjects were cut off and the other 12 patients were reserved). The effect of two different treatments on remaining lung was observed by surgical video.@*RESULTS@#A total of 26 translobar veins patterns were identified with an overall incidence of 82.26%, much greater in the right than in the left lung (80.65% vs 11.94%). The major types (frequency >5%) in the right lung include: the VX2 (5.48%) that flows into the inferior pulmonary vein behind the intermediate bronchus, the V3b (58.39%) that converges the venous branches of the upper and middle lobe, the VX4 that flows into the V2 (13.23%) or V3 (12.58%) in the horizontal fissure, the VX4 (8.71%) or VX5 (7.42%) that flows into the left atrium beneath the middle lobe bronchus, and the VX6 that flows into V2 in the Oblique fissure. The major types in the left lung include the common trunk (9.36%) of the superior and inferior pulmonary vein, of which 4.84% are greater than 1 cm in length. Compared to the preserved group, circulatory function of the remaining lung was impaired in the severed group, with the impaired area failing to collapse long after ventilation is stopped, the incidence of postoperative hemoptysis (13.89% vs 0.00%) and pulmonary air leakage (19.44% vs 8.33%) increased, the postoperative hospital stay [(4.72±1.86) d vs (3.92±1.62) d] was longer, and the total drainage during 3 days after operation [(705.42±265.02) mL vs (604.92±229.64) mL] was more, but the difference is not statistically significant.@*CONCLUSIONS@#There are a variety of types of translobar pulmonary veins and some of them have a high incidence; However, most of the translobar veins were neglected in surgery, which could adversely affect the safety of surgery and the recovery of patients after surgery.

ABSTRACT

There were three new blood group systems including the KANNO blood group system, the Sid blood group system and the CTL2 blood group system (provisional status), have been registered by the International Society of Blood Transfusion (ISBT) registered Science August 2019. The main reason for this update is that the significant SNPs of the KANNO blood group system (rs1800014) and the Sid blood group system (rs7224888) have been found through genome-wide association studies and whole exome sequencing. The new genetic evidences are consistent with the current immunological findings. In addition, although CTL2 antigen has been found on erythrocyte ghost (erythrocyte membrane) since 2017, CTL2 blood group system is still in provisional status due to lack of serological and genetic evidence. In this review, the experimental research advances of these three ISBT blood group systems and discuss the clinical value of the relevant researches was summarized briefly.
