The Fragment of Dunhuang Ancient Tibetan Moxibustion Therapy contains rich content on fire moxibustion therapy of Tubo-period Tibetan medicine, characterized by distinctive clinical features of Tibetan acupuncture and strong regional attributes. This paper systematically reviews the relevant materials on moxibustion in the Fragment and summarizes the findings as follows: Tibetan fire moxibustion mainly uses mugwort as the material, and terms like "fine mugwort", "broad bean" and "sheep dung pellet" refer to the size of the moxa cone. The number of moxa cones used is predominantly odd numbers, usually ranging from 5 to 21. The main indications for fire moxibustion cover internal medicine, external medicine, gynecology, pediatrics, and various pain syndromes. The therapy advocates for treating acute conditions and heat syndromes with moxibustion. The manuscript also records detailed contraindications, including time-based and seasonal taboos. Moxibustion is applied to both local and distal acupoints, reflecting the therapeutic concept of treating both proximal and distal regions. Furthermore, it documents simple and practical acupoint localization methods such as surface anatomical markers, proportional bone measurement, finger measurement, and hand-span measurement. Compared with contemporaneous Chinese medical moxibustion techniques, the moxibustion methods recorded in this Fragment are rich in content and present unique Tibetan theoretical characteristics. It provides valuable data and evidence for the excavation, application, and further research of Tibetan acupuncture and moxibustion.

Objective To study the pathological types,expression of mismatch repair protein,human epidermal growth factor receptor 2(HER2),and Pan-TRK,and Epstein-Barr virus(EBV)infection in patients with colorectal cancer resected in Tibet. Methods A total of 79 patients with colorectal cancer resected in Tibet Autonomous Region People's Hospital from December 2013 to July 2021 were enrolled in this study.The clinical and pathological data of the patients were collected.The expression of mismatch repair protein,HER2,and Pan-TRK was detected by immunohistochemical(IHC)staining,and detection of HER2 gene by fluorescence in situ hybridization(FISH)in the patients with HER2 IHC results of 2+ or above.EBV was detected by in situ hybridization with EBV-encoded small RNA. Results A total of 79 colorectal cancer patients were included in this study,with the male-to-female ratio of 1.26:1 and the mean age of(57.06±12.74)years(24-83 years).Among them,4 patients received preoperative neoadjuvant therapy.Colonic cancer and rectal cancer occurred in 57(57/79,72.15%,including 31 and 26 in the right colon and left colon,respectively)and 22(22/79,27.85%)patients,respectively.The maximum diameter of tumor varied within the range of 1-20 cm,with the mean of(6.61±3.33)cm.Among the 79 colorectal cancer patients,75(75/79,94.94%)patients showed adenocarcinoma.Lymph node metastasis occurred in 12(12/21,57.14%)out of the 21 patients with severe tumor budding,13(13/23,56.52%)out of the 23 patients with moderate tumor budding,and 2(2/31,6.45%)out of the 31 patients with mild tumor budding,respectively.The lymph node metastasis rate showed differences between the patients with severe/moderate tumor budding and the patients with mild tumor budding(all P<0.001).The IHC staining showed that mismatch repair protein was negative in 10(10/65,15.38%)patients,including 5 patients with both MSH2 and MSH6 negative,4 patients with both MLH1 and PMS2 negative,and 1 patient with MSH6 negative.Pan-TRK was negative in 65 patients.The IHC results of HER2 showed 0 or 1+ in 60 patients and 2+ in 5 patients.FISH showed no positive signal in the 5 patients with HER2 IHC results of 2+.The detection with EBV-encoded small RNA showed positive result in 1(1/65,1.54%)patient. Conclusions Non-specific adenocarcinoma of the right colon is the most common in the patients with colorectal cancer resected in Tibet,and 15% of the patients showed mismatch repair protein defects.EBV-associated colorectal carcer is rare,Pan-TRK expression and HER2 gene amplification are seldom.The colorectal cancer patients with moderate and severe tumor budding are more likely to have lymph node metastasis.

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.

Objective: To explore the vaccination coverage of the 13-valent pneumococcal conjugate vaccine (PCV13) in China from 2017 to 2021. Methods: Using the reported number of PCV13 administrated doses from 2017 to 2021 and the population data from 31 provinces in China, which were collected by the Immunization Program Information System and summarized data at different levels (prefecture, provincial, and national). Collecting batch release data of PCV13 during the same period through the official website of the National Institutes for Food and Drug Control. The average coverage level of PCV13 was calculated by comparing the number of PCV13 vaccinations reported annually to the number of births in that year, and the spatial auto-correlation analysis was conducted in 2021 at the prefecture level. The coverage of PCV13 vaccination was estimated by the total vaccine doses administered each year divided by the number of newborn in the year, as of the administrated dose number per 100 people. Results: From March 2017 to December 2020, the total batch release of PCV13 was 20.06 million, with a total of 71.54, 384.75, 475.45, and 10.8886 million doses each year. During the same period, PCV13 reported doses were 20.2369 million and the vaccination doses from 2017 to 2021 were 4.08, 170.46, 407.52, 599.77, and 8.4185 million doses, respectively. From 2017 to 2021, the ratio of PCV13 doses administrated per 100 infants in each year was 0.25, 10.26, 23.81, 38.16, and 69.90 doses per 100 people, respectively. The range of the ratio in each province increased from 3.85 doses in 2017 to 264.41 doses per 100 people in 2021. The spatial auto-correlation analysis results showed that based on prefecture-level cities, there was spatial clustering in a certain area of PCV13 coverage from 2017 to 2021, and the spatial correlation in 2021 was the highest. The hotspot analysis showed that the hotspot areas with high coverage levels of PCV13 were concentrated in Jiangsu, Zhejiang, Shanghai, Fujian and their surrounding areas. The cold spots with low vaccine coverage were concentrated in Yunnan, Qinghai, Tibet, and their surrounding areas. Conclusion: The average coverage level of PCV13 is low in China with significant regional differences.

OBJECTIVE: To investigate the risk factors of different types of Henoch-Schönlein purpura (HSP) in Tibetan patients at high altitude, as to provide reference for correctly identifying high-risk patients. METHODS: A retrospective study was used to analyze the 304 HSP patients admitted to Tibet Autonomous Region People's Hospital from April 2014 to March 2022. The gender, age, allergic history, family history, clinical type, laboratory indexes (hemoglobin, platelet count, eosinophil, C-reactive protein (CRP), albumin, immunoglobulin G, immunoglobulin A, complement C3 and C4) were analyzed retrospectively. Univariate and multivariate Logistic regression analysis to screen for risk factors affecting different types of HSP. RESULTS: Renal HSP patients showed higher IgA [(9.2±1.7) g/L vs. (6.4±2.4) g/L, P=0.015], lower complement C3 [(203.3±21.6) mg/dL vs. (301.1±19.5) mg/dL, P=0.043], and complement C4 [(33.5±2.3) mg/dL vs. (53.0±7.2) mg/dL, P=0.032]. The patients with abdominal HSP showed lower levels of hemoglobin [(119.6±19.6) g/L vs. (146.6±47.3) g/L, P=0.038] and plasma albumin [24.8 (22.1, 33.9) g/L vs. 32.6 (24.6, 35.1) g/L, P=0.045]. The patients with articular HSP exhibited higher CRP [13.5 (0.2, 20.6) g/L vs. 7.5 (0.1, 15.2) g/L, P=0.036] and erythrocyte sedimentation rate (ESR) [24 (5, 40) mm/h vs. 15 (4, 30) mm/h, P=0.049]. Elevated IgA and decreased complement C4 were risk factors for renal HSP, anemia and decreased plasma albumin were risk factors for abdominal HSP, and elevated CRP was a risk factor for articular HSP. CONCLUSION The clinical characteristics of different types of HSP in plateau areas were different. Patients with high IgA, low complement C4, anemia, hypoalbuminemia, and significantly elevated CRP should be highly vigilant. Early and effective intervention can improve the clinical efficacy, avoid severe development, and improve the prognosis.

In this study, a single base editing system was used to edit the FecB and GDF9 gene to achieve a targeted site mutation from A to G and from C to T in Ouler Tibetan sheep fibroblasts, and to test its editing efficiency. Firstly, we designed and synthesized sgRNA sequences targeting FecB and GDF9 genes of Ouler Tibetan sheep, followed by connection to epi-ABEmax and epi-BE4max plasmids to construct vectors and electrotransfer into Ouler Tibetan sheep fibroblasts. Finally, Sanger sequencing was performed to identify the target point mutation of FecB and GDF9 genes positive cells. T-A cloning was used to estimate the editing efficiency of the single base editing system. We obtained gRNA targeting FecB and GDF9 genes and constructed the vector aiming at mutating single base of FecB and GDF9 genes in Ouler Tibetan sheep. The editing efficiency for the target site of FecB gene was 39.13%, whereas the editing efficiency for the target sites (G260, G721 and G1184) of GDF9 gene were 10.52%, 26.67% and 8.00%, respectively. Achieving single base mutation in FecB and GDF9 genes may facilitate improving the reproduction traits of Ouler Tibetan sheep with multifetal lambs.

Objective: To study the prevalence and associated factors of metabolic syndrome (MS) among Tibetan pastoralists in transition from high altitude nomadic to settled urbanized environment, especially dietary factors. Methods: The community-based cross-sectional study included 920 Tibetan adults (men 419, women 501). Data were collected using questionnaires, anthropometric measurements, and biomarker tests. Questionnaires included socio-economic, lifestyle characteristics and food consumption. Principal component analysis was used to identify dietary patterns. The risk factors of MS and its components were analyzed by logistic regression model. Results: The prevalence rates of MS and its components were 32.8% (MS), 83.7% (decreased HDL-C), 62.1% (central obesity), 36.7% (elevated blood pressure), 11.8% (elevated TG), and 7.9% (elevated blood glucose), respectively. The prevalence of overweight was 31.2%, obesity 30.3%. Multivariate analysis showed smoking was associated factor for both of decreased HDL-C (OR=1.239, 95%CI: 1.025-1.496) and elevated TG (OR=1.277, 95%CI: 1.038-1.571). Alcohol drinking appeared as associated factor of elevated TG (OR=1.426, 95%CI: 1.055-1.927). However, physical activity showed as a protective factor for central obesity, decreased HDL-C, and elevated TG. With the increase of age, the adherence to the urban and western dietary patterns decreased, and that to the pastoral dietary pattern increased. By quintiles of dietary pattern scores, the urban dietary pattern was significantly associated with MS (trend test P=0.016). Conclusions: Tibetan pastoralists had high prevalence of both MS and obesity. Smoking, alcohol drinking, the transition from pastoral dietary pattern to urban dietary pattern and inadequate physical activity served as associated factors for MS and its components.
