Objective To analyze the etiological or associated factors and the treatment of patients with atrial fi brillation in high altitude areas in Tibet. Methods The clinical data of atrial fi brillation patients hospitalized in our hospital during January 2012 to Jane 2016 were analyzed retrospectively. Results (1) A total of 442 patients (male:female,1.2:1) were included in the study with ages of 30-96(65.9±12.3) years. The percentages of paroxysmal, persistent and permanent atrial fi brillation were 14.9%, 69.2%, and 15.8% respectively. The associated factors of atrial fi brillation included hypertension (53.4%), rheumatic heart disease (7.5%),chronic mountain sickness (10.6%), coronary heart disease(5.7%), hyperthyroidism (6.1%) and diabetes (9.0%).(2)Only 42 patients (9.5%) had evaluation with CHADS2score during hospitalization and actually 74.6% patients scored≥2. Twenty-one patients were restored to sinus rhythm during hospitalization and no patients had radiofrequency ablation.Conclusions The associated factors of atrial fi brillation in high altitude areas are similar to other areas. Thrombosis risk evaluation and anticoagulation therapy was not sufficient. Rhythm control rate was low and development of radio frequency ablation therapy should be considered.

Objective To compare the efficacy of operative and non-operative methods in the treatment of severe thoracic trauma in Tibetan Plateau.Methods A retrospective case-control study was conducted to analyze 286 patients with severe thoracic trauma admitted to the Shigatse People's Hospital from August 2016 to October 2018.There were 206 males and 80 females,aged 13-71 years [(34.3 ±11.6) years].The duration from injury to hospital ranged from 2 to 49 hours [(22.8 ± 8.3) hours].The causes of injury including fall from height in 109 patients,traffic injury in 98,crush injury in 32,blunt injury in 29,cattle head injury in 9,knife stab injury in 6 and other causes in 3.The injury severity score (ISS) varied from 16 to 48 points on admission [(24.2 ± 8.8) points].A total of 159 patients underwent operation (Operation group) and 127 patients underwent non-operative treatment (Non-operation group).The ISS score was (25.2 ± 8.3)points in Operation group and (23.7 ±7.9)points in Non-operation group.The length of hospital stay,intensive care unit (ICU) care time,complication rate and mortality were recorded in two groups.The correlation of ISS and age with mortality was investigated.Results The length of hospital stay was (12.2 ± 3.8) days in the Operation group and (19.7 ± 5.8) days in the Non-operation group (P ＜ 0.05).In the Operation group,27 patients were admitted to the ICU and stayed for (4.7 ± 1.3)days,and in the Non-operation group 33 patients were admitted to the ICU and stayed for (11.7 ± 3.2) days (P ＜ 0.05).The complication rate was 17.6％ in the Operation group and 31.5％ in the Non-operation group (P ＜0.05).Two patients died in the Operation group,with the mortality rate of 1.3％;six patients died in the Non-operation group,with the mortality rate of 4.7％,with no statistical difference (P ＞ 0.05).There were statistically significant differences in the age of death between the Operation group and the Non-operation group (P ＜ 0.05).The differences in the ISS score and age between the survival and death patients within the two groups were statistically significant (P ＜0.05).Logistic regression analysis showed age (OR =1.090,95％ CI 1.002-1.186) and ISS (OR =1.058,95％ CI 1.027-1.090) were slqnificantly related to mortality.Conclusions For severe thoracic trauma in Tibetan Plateau,operative treatment can shorten the length of hospital stay and ICU care time and reduce the incidence of complications.The mortality ratio of the two groups has no significant difference.Age and ISS may be the high risk factors for death of severe thoracic trauma patients.

Objective:To observe and evaluate the safety and efficacy of anti-vascular endothelial growth factor (VEGF) in the treatment of eyes with macular edema (ME) secondary to branch retinal vein occlusion (BRVO) in Lhasa, Tibet.Methods:A retrospective case series. From September 2018 to January 2022, a total of 41 patients (41 eyes) with BRVO-ME, who were diagnosed in Department of Ophthalmology of Tibet Autonomous Region People’s Hospital, were included in this study. There were 21 eyes in 21 males and 20 eyes in 20 females. The median age was 53 (31,75) years. There were 24 patients with hypertension (58.8%, 24/41). Best corrected visual acuity (BCVA), ocular pressure, fundus color photography and optical coherence tomography (OCT) were performed in all eyes. The BCVA was performed using the international standard logarithmic visual acuity chart, which was converted into logarithm of the minimum angle of resolution (logMAR) BCVA for record. The foveal macular thickness (CMT) was measured by OCT. All eyes were treated with intravitreous injection of anti-VEGF drugs, once a month, among which 23 eyes (56.1%, 23/41) received intravitreous injection of ranibizumab (IVR), and 18 eyes (43.9%, 18/41) received intravitreous injection of conbercept (IVC), and were grouped accordingly. There was no significant difference in age ( Z=-0.447), gender composition ( Z=-0.485), logMAR BCVA ( t=-1.591), intraocular pressure ( t=-0.167) and CMT ( t=-1.290) between two groups ( P>0.05). During the follow-up, the same devices and methods were used at baseline to perform relevant examinations, and the changes of BCVA, intraocular pressure, CMT and new cardiovascular and cerebrovascular events were compared between baseline and the last follow-up. logMAR BCVA, intraocular pressure and CMT were compared between baseline and last follow-up using Student t test. The comparison of injection times and follow-up time between IVR group and IVC group was conducted by Mann-Whitney U test. Results:At baseline, logMAR BCVA, intraocular pressure, and CMT were 0.852±0.431, (12.5±2.5) mm Hg (1 mm Hg= 0.133 kPa), and (578.1±191.1) μm, respectively. At the last follow-up, the number of anti-VEGF drug treatments was (2.7±1.2) times; logMAR BCVA and CMT were 0.488±0.366 and (207.4±108.7) μm, respectively, with CMT > 250 μm in 14 eyes (34.1%, 14/41). Compared with baseline, BCVA ( t=4.129) and CMT ( t=-0.713) were significantly improved, with statistical significance ( P<0.001). The injection times of IVR group and IVC group were (2.6±0.9) and (3.0±1.5) times, respectively. There were no significant differences in the number of injection times ( t=-1.275), logMAR BCVA ( t=-0.492), intraocular pressure ( t=0.351) and CMT ( t=-1.783) between the two groups ( P>0.05). No new hypertension, cardiovascular and cerebrovascular events occurred in all patients during follow-up. At the last follow-up, there were no eye complications related to treatment modalities and drugs. Conclusion:Short-term anti-VEGF treatment can improve the visual acuity of BRVO secondary ME patients and alleviate ME in Lhasa, Tibet. The safety and efficacy of ranibizumab and conbercept were similar.

To analyze the epidemiological characteristics of pulmonary tuberculosis (PTB) in Motuo County from 2012 to 2021 and provide evidence for the prevention and control of PTB. A total of 223 cases of PTB were reported from 2012 to 2021 in Motuo County, with an average annual reported incidence rate of 171.39/100 000. Joinpoint regression model analysis showed that the average decline rate was 9.2% (P<0.001) from 2012 to 2021. Among the various types of PTB patients reported from 2012 to 2021, there were 69 cases of etiologic-positive cases which increased from 28.57% to 52.63%. Results from the circular distribution methods showed that there was no obvious peak time of PTB in Motuo County. There was no statistical difference in the average annual incidence of PTB between different genders (χ²=0.108, P=0.743). Among all age groups, the 20-29 years group had the highest proportion (26.91%, 60/223). The Monpa ethnic group (153 cases, 68.61%) had the largest number of cases, followed by the Lhoba people (44 cases, 19.73%) and the Tibetan (22 cases, 9.87%). Farmers (168 cases, 75.34%) had the highest occupational composition ratio, followed by students (40 cases, 17.94%). The main detection methods of PTB were clinical consultation and transferring consultation. Overall, the incidence rate of PTB decreased from 2012 to 2021. The majority of PTB patients were young adults with high transmission risk. It is necessary to pay more attention to the key populations and strengthen the comprehensive prevention and control for reducing the risk of PTB.
