Objective:To investigate the effects of self-help mindfulness-based stress reduction (MBSR) training on illness uncertainty andsleep quality in patients with atrial fibrillation (AF) after radiofrequency ablation. To provide the basis for improving the quality of life of these patients.Methods:This was a randam controlled Test. A convenient sampling method was used to select 90 patients with atrial fibrillation who underwent radiofrequency ablation in the First Peoples Hospital of Changzhou from January 2021 to December 2021. According to the random number table method. They were divided into the experimental group and the control group, with 45 cases in each group. The control group received routine nursing, and the observation group received home-based self-help MBSR training based on the routine nursing. Five Facet Mindfulness Questionnaire (FFMQ), Mishel Uncertainty in Illness Scale and the Pittsburgh Sleep Quality Index Scale (PSQI) were used to evaluate the scores of each scale before intervention, 8 weeks and 3 months after intervention.Results:A total of 42 cases were completed in the experimental group and 41 cases in the control group. Repeated measurement analysis of variance showed that there were interaction effect ( F interaction = 90.98, 46.27, 39.61, all P<0.01), time effect ( F time = 298.67, 179.06, 76.32, all P<0.01) and inter-group effect ( F intergroup = 19.88, 4.07, 18.70, all P<0.05) on mindfulness score, disease uncertainty score, total score of sleep quality and scores of all dimensionsin between the two groups. Simple effect analysis showed that scores of all scales in experimental groups were significantly better than those in control group after the intervention ( F values were 11.75 to 66.49, all P<0.01). Conclusion:Self-help MBSR training can improve the level of mindfulness, reduce the feeling of uncertainty and improve the quality of sleep in patients with atrial fibrillation after radiofrequency ablation.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.

Objective:To compare the efficacy of 3D printing technology-assisted and conventional open reduction and internal fixation of multiple rib fracture.Methods:A retrospective cohort study was conducted to analyze the clinical data of 61 patients with multiple rib fracture admitted to Mindong Hospital Affiliated to Fujian Medical University and Fujian Provincial Hospital from July 2018 to March 2020. There were 44 males and 17 females, with age range of 18-73 years [(45.1±12.9)years]. Unilateral lung contusion and laceration occurred in 31 patients, while bilateral in 30. There were 19 patients accompanied by hempneumothorax and 16 by flail chest. Totally, 31 patients received 3D printing technology assisted open reduction and internal fixation (3D-assisted incision group) and 30 patients received conventional open reduction and internal fixation (conventional incision group). The incision length, operation time, intraoperative blood loss, postoperative 3-day visual analogue scale (VAS), duration of pain, indwelling time of chest tube, total length of hospital stay, postoperative bone callus formation time and rate of rib bone plate loosening were comapared in two groups. The short form 36 health survey (SF-36) score (ie, physical function, physical function, physical pain, general health, energy, social function, emotional function, mental health) preoperatively, at postoperative 6-month and at the last follow-up was compareted between two groups. Complications were observed at the same time.Results:All patients were followed up for 18-38 months [(26.4±5.5)months]. In 3D-assisted incision group, the incision length was (5.9±1.3)cm, with operation time for (84.6±7.8)minutes, intraoperative blood loss for (85.5±13.9)ml, postoperative 3-day VAS for (2.5±0.5)points, duration of pain for (5.9±0.7)days, indwelling time of chest tube for (3.4±0.7)days, total length of hospital stay for (7.0±1.0)days, postoperative callus formation time for (2.6±0.7)weeks and rate of rib bone plate loosening for 3.2%(1/31). By contrast, in conventional incision group, the incision length was (10.9±2.4)cm, with operation time for (127.1±12.5)minutes, intraoperative blood loss for (183.0±30.9)ml, postoperative 3-day VAS for (6.5±0.9)points, duration of pain for (11.2±1.8)days, indwelling time of chest tube for (7.8±0.8)days, total length of hospital stay for (15.1±1.2)days, postoperative callus formation time for (4.6±0.8)weeks and rate of rib bone plate loosening for 20.0%(6/30) ( P<0.05 or 0.01). There was no significant difference in preoperative SF-36 score between the two groups ( P>0.05). At 6 months after surgery, the subscores of SF-36 in 3D-assisted incision group were higher than those in conventional incision group except for "mental health" ( P<0.05 or 0.01). At the last follow-up, all the subscores of SF-36 in 3D-assisted incision group were higher than those in conventional incision group ( P<0.05 or 0.01). There were no obvious complications such as pulmonary infection or atelectasis. Conclusions:For multiple rib fracture, 3D printing technology-assisted open reduction and internal fixation is superior to conventional open reduction and internal fixation for it can shorten incision length, operation time, indwelling time of chest tube, total length of hospital stay and postoperative bone callus formation time, reduce intraoperative blood loss, relieve postoperative pain, reduce rate of rib bone plate loosening and improve quality of life of the patients.

Objective:To investigate the clinical effect of thoracoscopy combined with puncture-positioned internal fixation of multiple rib fractures accompanied with hemopneumothorax.Methods:A retrospective case-control study was used to analyze the clinical data of 68 patients with multiple rib fractures accompanied with hemopneumothorax admitted to Fujian Provincial Hospital from September 2016 to December 2018, including 49 males and 19 females, aged 25-86 years [(47.3±7.4)years]. There were 55 patients with unilateral lung contusion and laceration, and rest 13 patients with bilateral lung contusion and laceration. A total of 36 patients were treated by thoracoscopy combined with puncture-positioned internal fixation (thoracoscopy group) and 32 patients by open reduction group (open reduction group). The incision length, operation time, intraoperative blood loss, chest tube drainage time, ICU hospitalization time, total hospitalization time, and complications were recorded. Numeric rating scale (NRS) score was assessed at postoperative 1, 2, 3, 7 days. The MOS 36-item short-form health survey (SF-36) was conducted at the latest follow-up.Results:All patients were followed up for 8-34 months [(18.9±4.3)months]. Thoracoscopy group showed incision length of (4.3±1.3)cm, operation time of (66.3±12.1)minutes, intraoperative blood loss of (86.5±23.4)ml, chest tube drainage time of (5.3±1.1) days, ICU hospital stay of (2.3±0.8)days, total hospital stay of (6.8±1.7)days, and total complication rate of 8%, showing significant differences compared to open reduction group [(11.6±2.2)cm, (105.9±19.4)minutes, (191.4±35.6)ml, (8.1±1.6)days, (4.7± 1.4)days, (10.6±2.1)days, 29%] ( P<0.05 or 0.01). In thoracoscopy group, the NRS scores at day 1, 2, 3, and 7 were respective (6.6±1.2)points, (5.9±1.0)points, (4.4±0.9)points and (2.7±0.7)points, significantly lower than those in open reduction group [(7.3±1.2)points, (7.0±1.1)points, (5.7±1.0)points and (3.9±0.8)points] ( P<0.05 or 0.01). The SF-36 score in thoracoscopy group was (86.4±12.1)points, significantly higher than that in open reduction group [(75.6±11.5)points] ( P<0.01). Conclusions:Compared with open reduction and internal fixation, thoracoscopy combined with puncture-positioned internal fixation for multiple rib fractures has the advantages of smaller surgical incision, shorter operation time, less intraoperative bleeding, shorter chest tube drainage time, shorter ICU hospital stay, shorter total hospital stay, and less postoperative complications. The technique can also reduce the postoperative pain and improve the patients' quality of life.

Objective To study the clinical value of virtual segmentectomy based on three-dimensional computed tomography bronchography and angiography (3D-CTBA) in thoracoscopic segmentectomy for early-stage lung cancer. Methods Totally 18 patients received thoracoscopic segmentectomy from July 2015 to July 2016 were performed virtual segmentectomy based on 3D-CTBA. The preoperative planning depended on the simulation result. Results All of the 18 cases(1 right Sl, 2 right S3, 3 right S6, 1 right S8 +9, 1 right S9 + 10, 3 left S1 +2 +3, 3 left S4 +5, 4 left S6 segmentectomies)were received thoracoscopic segmentectomy successfully. The mean operation time and intraoperative blood loss were (126.8士19.4) mins and(76.6±21.4) ml respectively. Pathological examination revealed no residual tumor cells at the surgical margins and no lymph node metastases in any patients. The actual surgical margins were all larger than 2 cm(2.37±0.39)cm. Conclusion Virtual segmentectomy based on 3D-CTBA can non-invasively visualize the relationship between the safe margin and segmental vessels and bronchi. It facilitates the preoperative planning of suitable segmentectomy procedure for patients with early-stage lung cancer.

Objective To establish and evaluate the animal model induced by inhalation injury of airborne fine particulate matter (PM2?5). Methods We manufactured equipment for rats aerosol inhalation with PM2?5. The effects of several facters such as concentrations(100 ± 10 μg/m3、150 ± 10 μg/m3、200 ± 10 μg/m3 )、time(1w、2w、4w、8w、12w)、method (non?exposed intratracheal instillation method and aerosol inhalation) and animals (Wistar rats, BN rats and guinea pigs) were investigated to establish the model. The respiratory rate, forced vital capacity ratio of forced expiratory volume ( FEV1/FVC) and arterial partial pressure of oxygen ( PO2 ) were measured, the pathological changes of bronchial and lung tissues under light microscope were observed. The success animal model was builded as the pneumonia was observed from the pathological changes of lung tissue. Results The Wistar rats exposed to PM2?5 aerosol inhalation for 8 weeks, we can see that the weight growth rate of rat decreased, WBC count and mononuclear cells count increased, the macrophages ratio decreased in BALF, the respiratory rate of lung increased while arterial PO2 and FEV1/FVC decreased, inflammation and pulmonary fibrosis changes were observed by bronch and pulmonary pathology, inflammatory changes with a dose?response relationship were observed. Exposed to PM2?5 aerosol inhalation for different time(1 w、2 w、4 w、8 w、12 w)with same dose, the score issue lesions of lung and bronchus in Wistar rats increased and the 8w group is obvious. The Wistar rats exposed to PM2?5 with different method ( aerosol inhalation and non?exposed intratracheal instillation method) for 8w, the aerosol inhalation worked as effectively as perfusion while mortality rate of aerosol inhalation is lower. Different animals ( Wistar rats, BN rats and guinea pigs) exposed to PM2?5 aerosol inhalation for 8w, the same results were observed with three method respectively while mortality rate of Wistar rats lower. Conclusions The optional conditions that the Wistar rats were continuously inhaled for 8w PM2?5 with a dose of 150 ± 10 μg/m3 were established. The animal model could be used on a national scale, especially in Fujian province. The results would be useful for the development of the research of the prevention and countermeasures of PM2?5 pollution.

From June 2008 to December 2012,video-assisted thoracoscopic surgery (VATS group) was performed for 24 cases of thymoma.Their operative procedures,postoperative complications,remission of myasthenia gravis (MG),perioperative mortality and oncological outcomes were compared with 19 cases of trans-sternal open thymectomy (OT group).Compared with OT group,VATS group had significantly shorter operation duration,less blood loss,shorter postoperative hospital stay,shorter chest tube duration and less chest drainage amount (P ＜ 0.05).The total rate of postoperative complications of VATS group was 4％ (1/24) and it was less than OT group (4/19) without significant difference (P ＞0.05).The effective remission rate of thymomatous MG was 7/9 in VATS group and it was similar to that in OT group (6/8,P ＞ 0.05).VATS group had a recurrent or metastatic rate of 0％ (0/23) and it was better than OT group with 1/17.And there was no significant inter-group difference (P ＞ 0.05).The total survival rate of VATS group was 100％ and it was similar to that of OT group (16/17,P ＞ 0.05).Thoracoscopic thymectomy is safe,feasible,efficacious and mini-invasive for thymoma.With fewer complications and a quicker recovery,it has similar short-term outcomes to conventional open thymectomy.

To get information in the sexual and contraceptive behaviors in Chinese female college students, a randomized cluster sampling was conducted in colleges and universities in Wuhan Area,China, in terms of types of colleges, subjects (literature, sciences, medicines, art etc), and grades etc.A total number of 2450 questionnaires were distributed, with 2365 questionnaires returned being valid. The return rate of valid questionnaires was 96.6%. The questionnaire investigation was conducted on a multiple-choice and anonymous basis. Data were input into computer and SPSS12.0software package was employed for statistical analysis. Among the female students, 1196 had the experiences of hugging and kissing (50.57%) and 423 (17.89%) had sexual experiences (sexual intercourse). The first sexual intercourse took place at the age of 19.23±1.74 y. There were significant differences in the sexual experiences among the majors of different subjects, with the rate of sexual experiences in art majors (43.17%) and high-grade students (34.31%) being the highest. The causes of the first sexual intercourse included sexual impulse, curiosity, intention to strengthen the relationship or to show loyalty to boyfriend and sometimes violence. While the motives of the sexual intercourse within the past one year before the investigation were to satisfy the sexual needs and to strengthen the relation with their boyfriends. With both first intercourse and sexual experiences within last one year,the partners of the sexual intercourse were mainly their boyfriends (95.7% and 97.3% respectively),but the partners also included acquaintances, "one night stand" partners and customers of sex trade.Some of them had multiple sexual partners, with the highest number of the sexual partners being 11.In the first sexual intercourse of the subjects, 44.0% of them did not take any contraceptive measures;only 16.4 % of them used condoms. In the sexual intercourse within the last one year, only 44.6%took contraceptive measures every time they had sexual intercourse. Among those who took contraceptive measures, 64.4% used condoms. Among those who had sexual intercourse, 101 persons got pregnant, with a rate of pregnancy being 4.3%, accounting for 23.9 % of all who had sexual intercourse. Among those who got pregnant, 78 persons got pregnant once; the others became pregnant more than two times, the highest being 5 times. There were 122 persons who had inflammation of reproductive system, mostly vaginitis. Other conditions included venereal warts and herpes genitalis. It is concluded that the rate of sexual behaviors is high in female college students and there exist promiscuity, unexpected pregnancy and transmission of STD in the students.
