RESUMO

Objective: To assess the effectiveness of a 6-month Ba Duan Jin exercise program in improving the balance of community-dwelling older adults. Methods: A two arms, parallel-group, cluster randomized controlled trial was conducted in 1 028 community residents aged 60-80 years in 40 communities in 5 provinces of China. Participants in the intervention group (20 communities, 523 people) received Ba Duan Jin exercise 5 days/week, 1 hour/day for 6 months, and three times of falls prevention health education, and the control group (20 communities, 505 people) received falls prevention health education same as the intervention group. The Berg balance scale (BBS) score was the leading outcome indicator, and the secondary outcome indicators included the length of time of standing on one foot (with eyes open and closed), standing in a tandem stance (with eyes open and closed), the closed circle test, and the timed up to test. Results: A total of 1 028 participants were included in the final analysis, including 731 women (71.11%) and 297 men (28.89%), and the age was (69.87±5.67) years. After the 3-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 3.05 (95%CI: 2.23-3.88) points (P<0.001). After the 6-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 4.70 (95%CI: 4.03-5.37) points (P<0.001). Ba Duan Jin showed significant improvement (P<0.05) in all secondary outcomes after 6 months of exercise in the intervention group compared with the control group. Conclusions: This study showed that Ba Duan Jin exercise can improve balance in community-dwelling older adults aged 60-80. The longer the exercise time, the better the improvement.

RESUMO

Objective: To investigate the risk factors for the occurrence of laryngopharyngeal reflux disease in the aged, and to analyze the characteristics of patients with pneumonia. Methods: Patients who underwent 24-hour laryngopharyngeal pH monitoring from June 2020 to July 2022 and the positive patients of those who underwent 24-hour esophageal pH monitoring from March 2017 to July 2022 at the Second Medical Center of the PLA General Hospital were enrolled retrospectively. Positive results of 24-hour laryngopharyngeal reflux monitoring were in the laryngopharyngeal reflux group, and the negative results were in the non-laryngopharyngeal reflux group. Patients with pneumonia and simple gastroesophageal reflux disease were in the esophageal reflux pneumonia group, and patients with pneumonia and simple laryngopharyngeal reflux disease were in the laryngopharyngeal reflux pneumonia group. Patients' basic data, co-morbidities, drug use and relevant examination and test results were collected. Multivariate logistic regression analysis was used to analyze the risk factors of laryngopharyngeal reflux disease in the aged and its relationship with pneumonia. Results: A total of 80 patients with 24-hour laryngopharyngeal pH monitoring were enrolled finally, including 34 cases, all male, aged (73±12) years, in the laryngopharyngeal reflux group, and 46 cases [44 males, 2 females, aged (78±11) years] in the non-laryngopharyngeal reflux group. Multivariate logistic regression analysis showed that the risk factors of laryngopharyngeal reflux disease in the aged included age ≤70 years (OR=13.07, 95%CI: 2.53-67.68), body mass index (BMI) (OR=1.37, each additional 1 kg/m2, 95%CI: 1.03-1.83), use of antipsychotic drugs (OR=8.00, 95%CI: 1.40-45.73) and calcium channel blockers (OR=5.27, 95%CI: 1.13-24.53) (all P<0.05). The protective factors of the laryngopharyngeal reflux disease in the aged included antacids (OR=0.19, 95%CI: 0.04-0.90, P=0.035). The incidence of pneumonia was higher in the laryngopharyngeal reflux group compared with the non-laryngopharyngeal reflux group [44.1% (15/34) vs 21.7% (10/46), P=0.033]. The esophageal reflux pneumonia group included 32 cases [31 males and 1 females, aged (84±12) years]. The laryngopharyngeal reflux pneumonia group included 15 cases [ 15 males, aged (79±11) years]. Compared to the patients in the laryngopharyngeal reflux pneumonia group, the patients in the esophageal reflux pneumonia group had a longer course of antibiotics [(27.7±27.0) vs (14.6±13.9) days, P=0.034], a higher frequency of seizure frequency [(4.3±3.0) vs (1.8±1.5) times/year, P<0.001] and a higher maximal body temperature [(38.2±0.9) vs (37.6±1.1) ℃, P=0.037]. Conclusions: The risk factors of laryngopharyngeal reflux disease in the aged included age ≤70 years, higher BMI, use of antipsychotic drugs and calcium channel blockers. The incidence of pneumonia in laryngopharyngeal reflux disease is higher, but the condition of pneumonia is milder.

RESUMO

Objective: To explore the application effects of mind mapping combined with scenario simulation training on the ability training of junior nurses in hospital transfer of patients with critical burns and trauma. Methods: A prospective randomized controlled study was conducted. From December 2019 to December 2020, 55 female junior nurses from the Institute of Burn Research of the First Affiliated Hospital of Army Medical University (the Third Military Medical University) who met the inclusion criteria were enrolled in this study and divided into routine group (27 nurses, aged (24.0±0.9) years) and combined group (28 nurses, aged (24.2±0.8) years), according to the random number table. The nurses in routine group were trained with hospital transfer of patients with critical burns and trauma by theory combined with operational skill, and the nurses in combined group were trained with hospital transfer of patients with critical burns and trauma by mind mapping combined with scenario simulation training. Before and after the training, the self-made theoretical examination papers and skill assessment items were used for the examination and assessment to nurses, and their scores were calculated and compared. The self-made emergency ability scoring system was used to evaluate the emergency disposal ability of nurses from five dimensions, including team cooperation ability, emergency response ability, operative technique ability, specialized business ability, and nurse-patient communication ability, and their scores were calculated and compared. The non-standard implementation rates of transfer nursing measures, such as incomplete preparation of goods, poor communication effect of patients, inadequate pipeline nursing, unclear handover, and inadequate final treatment, were calculated and compared in the process of transporting highly simulated human (hereinafter referred to as simulated human) by nurses before and after training; and the rate of disease change and successful rate of transport of simulated human were calculated and compared after training. After assessment, self-made satisfaction questionnaire was used to compare nurses' satisfaction with the training mode, content, and effects. Data were statistically analyzed with independent sample t test, Pearson chi-square test, or Yates corrected chi-square test. Results: Fifty-five enrolled nurses were fully involved in the training, examination, assessment, and questionnaire filling. Before training, there were no statistically significant differences in theoretical examination and skill assessment scores between the 2 groups (P>0.05); After training, the theoretical examination and skill assessment scores of nurses in combined group were significantly higher than those in routine group (with t values of -3.89 and -4.24, respectively, P<0.05). Before training, there were no statistically significant differences in the scores of each item of emergency disposal ability between the 2 groups (P>0.05); after training, the scores in terms of team cooperation ability, emergency response ability, operative technique ability, specialized business ability, and nurse-patient communication ability of nurses in combined group were significantly higher than those in routine group (with t values of -6.49, -6.44, -2.21, -2.85, and -2.34, respectively, P<0.05). Before training, there were no statistically significant differences in the non-standard implementation rates of transfer nursing measures of nurses between the 2 groups (P>0.05); after training, the non-standard rates of incomplete preparation of goods, unclear handover, and inadequate final treatment of nurses in combined group were significantly lower than those in routine group (with t values of 3.87, 5.89, and 5.28, respectively, P<0.05). After training, the rate of disease change of simulated human of nurses in combined group was 7.14% (2/28), which was significantly lower than 33.33% (9/27) in routine group (χ2=5.89, P<0.05); the successful rate of transport was 96.43% (27/28), which was significantly higher than 74.07% (20/27) in routine group (χ2=3.87, P<0.05). After assessment, the total score of training satisfaction and scores of satisfaction with training mode and training effect of nurses in combined group were significantly higher than those in routine group (with t values of 5.22, 4.67, and 10.71, respectively, P<0.05). There was no statistically significant difference in the satisfaction score on training content between the two groups (P>0.05). Conclusions: Evidence-based mind mapping combined with scenario simulation training significantly improves the nursing skills and emergency handling capabilities of junior nurses in transferring patients with critical burns and trauma.

RESUMO

Atopic dermatitis(AD)is a chronic, recurrent, inflammatory skin disease in children. The disease is characterized by dryness, chronic eczema-like lesions and obvious itching, seriously affecting the quality of life of children and their families. The pathogenesis of AD is not yet to be clear, and it might be the interaction of genetic susceptibility and environmental exposure to induce skin barrier impairment and immune system dysfunction. In recent years, the role of maternal factors or intrauterine environment exposure on childhood allergic diseases has been attracted attention, and the hypothesis that allergic diseases originate from the fetal period has been postulated. Maternal exposures called "early life exposure", such as nutritional factors during pregnancy (folate, vitamin D, vitamin E and polyunsaturated fatty acid) and tobacco exposure, home environmental exposure may be related with childhood atopic dermatitis. This article would focus on the recent research about maternal nutritional factors and family environmental exposure during pregnancy on offspring's atopic dermatitis.

RESUMO

Objective: To compare the incidence of radiation-related toxicities between conventional and hypofractionated intensity-modulated radiation therapy (IMRT) for limited-stage small cell lung cancer (SCLC), and to explore the risk factors of hypofractionated radiotherapy-induced toxicities. Methods: Data were retrospectively collected from consecutive limited-stage SCLC patients treated with definitive concurrent chemoradiotherapy in Cancer Hospital of Chinese Academy of Medical Sciences from March 2016 to April 2022. The enrolled patients were divided into two groups according to radiation fractionated regimens. Common Terminology Criteria for Adverse Events (CTCAE, version 5.0) was used to evaluate the grade of radiation esophagus injuries and lung injuries. Logistic regression analyses were used to identify factors associated with radiation-related toxicities in the hypofractionated radiotherapy group. Results: Among 211 enrolled patients, 108 cases underwent conventional IMRT and 103 patients received hypofractionated IMRT. The cumulative incidences of acute esophagitis grade ≥2 [38.9% (42/108) vs 35.0% (36/103), P=0.895] and grade ≥ 3 [1.9% (2/108) vs 5.8% (6/103), P=0.132] were similar between conventional and hypofractionated IMRT group. Late esophagus injuries grade ≥2 occurred in one patient in either group. No differences in the cumulative incidence of acute pneumonitis grade ≥2[12.0% (13/108) vs 5.8% (6/103), P=0.172] and late lung injuries grade ≥2[5.6% (6/108) vs 10.7% (11/103), P=0.277] were observed. There was no grade ≥3 lung injuries occurred in either group. Using multiple regression analysis, mean esophageal dose ≥13 Gy (OR=3.33, 95% CI: 1.23-9.01, P=0.018) and the overlapping volume between planning target volume (PTV) and esophageal ≥8 cm(3)(OR=3.99, 95% CI: 1.24-12.79, P=0.020) were identified as the independent risk factors associated with acute esophagitis grade ≥2 in the hypofractionated radiotherapy group. Acute pneumonitis grade ≥2 was correlated with presence of chronic obstructive pulmonary disease (COPD, P=0.025). Late lung injuries grade ≥2 was correlated with tumor location(P=0.036). Conclusions: Hypofractionated IMRT are tolerated with manageable toxicities for limited-stage SCLC patients treated with IMRT. Mean esophageal dose and the overlapping volume between PTV and esophageal are independently predictive factors of acute esophagitis grade ≥2, and COPD and tumor location are valuable factors of lung injuries for limited-stage SCLC patients receiving hyofractionated radiotherapy. Prospective studies are needed to confirm these results.

RESUMO

The ^{18}O(α,γ)^{22}Ne reaction is critical for AGB star nucleosynthesis due to its connection to the abundances of several key isotopes, such as ^{21}Ne and ^{22}Ne. However, the ambiguous resonance energy and spin-parity of the dominant 470 keV resonance leads to substantial uncertainty in the ^{18}O(α,γ)^{22}Ne reaction rate for the temperature of interest. We have measured the resonance energies and strengths of the low-energy resonances in ^{18}O(α,γ)^{22}Ne at the Jinping Underground Nuclear Astrophysics experimental facility (JUNA) with improved precision. The key 470 keV resonance energy has been measured to be E_{α}=474.0±1.1 keV, with such high precision achieved for the first time. The spin-parity of this resonance state is determined to be 1^{-}, removing discrepancies in the resonance strengths in earlier studies. The results significantly improve the precision of the ^{18}O(α,γ)^{22}Ne reaction rates by up to about 10 times compared with the previous data at typical AGB temperatures of 0.1-0.3 GK. We demonstrate that such improvement leads to precise ^{21}Ne abundance predictions, with an impact on probing the origin of meteoritic stardust SiC grains from AGB stars.

RESUMO

Gallnut (Mo Shi Zi), as one of the herbs popularly used in traditional Chinese medicine, came into China from Persia in the Northern Wei Dynasty. Gallnut was translated into different names from Persian into Chinese. This study attempted to identify its names, sources and nature by starting with Mo Shi Zi () and comparing with its relevant names Mo Shi Zi(),Ba Lv Zi () and Wu Bei Zi (). It was found that'', meaning black, in Mo Shi Zi () did not make sense because it neither matched the pronunciation in translation nor interpreted the medical meaning of Mo Shi Zi (). Mo Shi Zi () and Ba Lv Zi() were the same herb in traditional Chinese medicine. In Greek and Arabic classic books, Bullut referred to oak groups and their galls, but not Ba Lv Zi (). Ba Lv Zi () in these books referred to Omphacitis. Mo Shi Zi () referred to insect galls in the family of Quercus infectoriain Xi Yao Da Cheng, a book from overseas, and Wu Bei Zi ()appeared in the annotated text of Mo Shi Zi () as a similar herb. It was found that in traditional Chinese medicine, Mo Shi Zi () and Wu Bei Zi( ) were two different herbs, but could be interchanged in their medical nature.

RESUMO

Objective: To understand the volatile organic components in the organic solvents used by enterprises in Baoan District, Shenzhen. Methods: From January to December 2020, a total of 541 organic solvent samples used by 86 companies were collected for volatile organic component analysis, and the main volatile components and high-risk occupational hazards in organic solvents used in different industries were analyzed. Results: A total of 201 volatile organic components were detected in 541 organic solvents. The top 5 components detected include xylene (29.76%, 116/541), toluene (21.81%, 118/541), methanol (20.70%, 112/541), n-hexane (14.79%, 80/541) and ethylbenzene (14.23%, 77/541). The detection rates of benzene, trichloroethylene, n-hexane, and 1, 2-dichloroethane, which were high-risk occupational hazards, were 2.40% (13/541), 3.70% (20/541), 14.79% (80/541), and 1.66% (9/541), respectively. The volatile components in organic solvents used in different industries was different. Benzene is more frequently detected in organic solvents used in the printing industry, trichloroethylene was more frequently detected in organic solvents used in the electronics industry, and n-hexane was more commonly found in organic solvents used in the electronics industry, printing and other industries, and 1, 2-dichloroethane has been more frequently detected in organic solvents used in the machinery industry. Conclusion: There are many types of organic solvents used by enterprises in Bao'an District, with complex components and differences in different industries.

RESUMO

OBJECTIVE: To evaluate the efficacy of plasma exchange therapy on crescentic IgA nephropathy (IgAN). METHODS: A retrospective analysis was performed in a cohort of patients with crescentic IgAN from January 2012 to September 2020 at 9 sites across China. Clinical and pathological data, as well as therapeutic regimens, were collected. In order to minimize the effect of potential confounders in baseline characteristics, propensity score matching using a 1 ∶1 ratio nearest neighbor algorithm was performed between the adjunctive plasma exchange therapy group and the intensive immunosuppressive therapy group. The primary outcome was end-stage of kidney disease (ESKD). Kaplan-Meier method was used to compare the difference in renal survival between the two groups. RESULTS: A total of 95 crescentic IgAN patients with acute kidney disease were included in this study, including 37 (38.9%) patients receiving adjunctive plasma exchange therapy, and 58 (61.1%) patients receiving intensive immunosuppressive therapy. In the whole cohort, the baseline eGFR was 12.77 (7.28, 21.29) mL/(min·1.73 m2), 24-hour urinary protein quantification was 5.9 (4.0, 8.9) g, and crescent percentage was 64.71% (54.55%, 73.68%). In the study, 23 patients in each group were matched after propensity score matching The median follow-up time was 7 (1, 26) months. As a whole, 29 patients (63.0%) reached ESKD, including 16 patients (69.6%) in the adjunctive plasma exchange therapy group and 13 (56.5%) patients in the intensive immunosuppressive therapy group.. There were no stastical difference between the two groups in terms of baseline eGFR [14.30 (9.31, 17.58) mL/(min·1.73 m2) vs. 11.45 (5.59, 20.79) mL/(min·1.73 m2)], 24-hour urinary protein (7.4±3.4) g vs. (6.6±3.8) g, crescent percentage 64.49%±13.23% vs. 66.41%±12.65% and the proportion of patients received steroid therapy[23 (100.0%) vs. 21 (91.3%)] (All P>0.05). Kaplan-Meier survival analysis demonstrated that there was no significant difference in renal survival rate between the two groups (Log-rank test, P=0.933). CONCLUSION: The adjunctive plasma exchange therapy in addition to conventional intense immunosuppressive therapy did not additionally improve the prognosis of crescentic IgA nephropathy.

RESUMO

The ^{13}C(α,n)^{16}O reaction is the main neutron source for the slow-neutron-capture process in asymptotic giant branch stars and for the intermediate process. Direct measurements at astrophysical energies in above-ground laboratories are hindered by the extremely small cross sections and vast cosmic-ray-induced background. We performed the first consistent direct measurement in the range of E_{c.m.}=0.24 to 1.9 MeV using the accelerators at the China Jinping Underground Laboratory and Sichuan University. Our measurement covers almost the entire intermediate process Gamow window in which the large uncertainty of the previous experiments has been reduced from 60% down to 15%, eliminates the large systematic uncertainty in the extrapolation arising from the inconsistency of existing datasets, and provides a more reliable reaction rate for the studies of the slow-neutron-capture and intermediate processes along with the first direct determination of the alpha strength for the near-threshold state.

RESUMO

Objective: To understand the prevalence of osteoporosis and related factors in postmenopausal women aged ≥40 years in China and provide scientific evidence for osteoporosis prevention and control. Methods: Data of this study were from the 2018 China Osteoporosis Epidemiological Survey, covering 44 counties (districts) in 11 provinces in China. Related variables were collected by questionnaire survey and physical measurement, and the BMD of lumbar spine and proximal femur was measured by dual-energy X-ray absorption method. The prevalence of osteoporosis and its 95%CI in postmenopausal women aged ≥40 years were estimated with complex sampling weights. Results: A total of 5 728 postmenopausal women aged ≥40 years were included in the analysis and the prevalence of osteoporosis was 32.5% (95%CI: 30.3%-34.7%). The prevalence of osteoporosis in postmenopausal women aged 40-49 years, 50-59 years, 60-69 years, 70-79 years, and ≥80 years were 16.0% (95%CI:4.5%-27.5%), 18.4% (95%CI:15.9%-20.8%), 37.5% (95%CI:34.5%-40.4%), 52.9% (95%CI: 47.5%-58.3%), and 68.0% (95%CI:55.9%-80.1%) respectively. The prevalence of osteoporosis was higher (P<0.001) in those with education level of primary school or below (47.2%, 95%CI: 43.0%-51.3%) and in those with individual annual income less than 10 000 Yuan, (40.3%, 95%CI: 36.9%-43.7%). The prevalence of osteoporosis was 35.1% in rural areas (95%CI: 32.0%-38.1%), which was higher than that in urban areas (P<0.001). The prevalence of osteoporosis in low weight, normal weight, overweight and obese groups were 69.9% (95%CI: 59.0%-80.8%), 42.2% (95%CI: 38.7%-45.7%), 24.2% (95%CI: 21.3%-27.1%) and 14.6% (95%CI: 11.1%-18.0%), respectively. The prevalence of osteoporosis in those with menstrual maintenance years ≤30 years and in those with menopause years ≥11 years were 46.1% (95%CI:40.8%-51.3%) and 48.2% (95%CI:45.0%-51.3%), respectively. Multivariate logistic analysis showed that age ≥60 years, education level of primary school or below, annual household income per capita less than 10 000 Yuan, low body weight, menstrual maintenance years ≤30 years, menopause years ≥11 years were risk factors of osteoporosis in postmenopausal women in China. Conclusions: The prevalence of osteoporosis was high in postmenopausal women aged ≥40 years in China, and there were differences in osteoporosis prevalence among different socioeconomic groups. Effective interventions should be taken for the prevention and control of osteoporosis in key groups in the future.

RESUMO

Objective: To understand the prevalence of chronic cough, chronic expectoration and dyspnea and related factors in residents aged ≥40 years in China, and provide basic data for the prevention and control of chronic respiratory diseases. Methods: Data were from 2014-2015 chronic obstructive pulmonary disease surveillance in China. The information about chronic respiratory symptoms were collected by face-to-face interview. The prevalence rates of chronic cough, chronic expectoration, dyspnea and chronic respiratory symptoms and their 95%CI were estimated with complex sampling weights. Results: A total of 75 082 subjects were included in the analysis. The prevalence rates of chronic cough, chronic expectoration, dyspnea and chronic respiratory symptoms in the Chinese aged ≥40 years were 3.75% (95%CI: 3.38%-4.11%), 5.83% (95%CI: 5.40%-6.26%), 2.45% (95%CI: 2.02%-2.87%) and 8.93% (95%CI: 8.25%-9.62%), respectively. The prevalence rates of chronic cough, chronic expectoration, dyspnea and chronic respiratory symptoms in patients with chronic respiratory diseases were relatively higher, which were 10.27%, 13.85%, 6.43%, 20.72% respectively. Multivariate logistic regression analysis showed that age, region, education level, occupation, BMI, family history of respiratory diseases, history of severe respiratory infections in childhood, exposure to dust or chemicals in workplace and smoking status affected the prevalence of chronic cough, chronic expectoration and dyspnea. The prevalence of the three types of chronic respiratory symptoms increased significantly with age, which were higher in western region, smokers and underweight/obese subjects. The three prevalence rates mentioned above were higher in those with a history of severe respiratory infection in childhood, those exposed to biomass fuel in household, and those exposed to dust or chemicals in workplace. Conclusions: The prevalence rate of chronic respiratory symptoms was high in residents aged ≥40 years in China. Many factors affected the prevalence of chronic respiratory symptoms. Comprehensive prevention and control measures targeting risk factors should be taken to reduce the burden of chronic respiratory diseases.

RESUMO

Objective: To explore the expression of programmed cell death ligand 1 (PD-L1) in patients with locally advanced and non-EGFR-mutated non-small cell lung cancer (LA-NSCLC) undergoing concurrent chemoradiotherapy (cCRT) and its association with clinical outcome of patients. Methods: The basic clinical information of 19 patients with unresectable, non-EGFR mutated LA-NSCLC receiving radical cCRT in Cancer Hospital Chinese Academy of Medical Sciences from January 2016 to December 2017 was retrospectively analyzed. The rabbit monoclonal antibody SP263 was used for immunohistochemical analysis to detect the expression of PD-L1 in LA-NSCLC tissues and the tumor proportion score (TPS) equal to or greater than 1% was defined as PD-L1 positive. The associations between PD-L1 ≥1% and PD-L1 ≥25% with the clinical characteristics and clinical outcome of LA-NSCLC patients were evaluated respectively. Results: Among 19 LA-NSCLC patients, 13 had PD-L1 positive expression, and 4 had PD-L1 expression greater than or equal to 25%. No significant difference was observed between patients with PD-L1 positive and negative expressions regarding the distribution of age, smoking history, pathological classification, and TNM staging (P>0.05). A total of 15 patients could be evaluated for therapeutic effect, including 7 patients with partial response (PR), 7 patients with stable disease (SD), and 1 patient with progressive disease (PD). In the group with PD-L1 expression<1%, 3 patients were in objective response, and 4 patients were in disease control. In the group with PD-L1 expression ≥1%, 4 patients were in objective response, and 10 patients were in disease control. When the PD-L1 expression was less than 25%, 6 patients gained the objective response, and 11 patients gained the disease control. When the PD-L1 expression was greater than or equal to 25%, 1 patient gained the objective response, and 3 patients gained the disease control. The median overall survival (OS) was 35 (95%CI: 12.7-57.3) months for patients with PD-L1 ≥1% and 40 (95%CI: not reaching the end point) months for patients with PD-L1<1% (P=0.284). Patients with PD-L1 ≥25% had a median survival time of 12 (95%CI:0.0-34.5) months, and patients with PD-L1<25% had a median survival time of 40 (95%CI: 27.4-52.6) months (P=0.241). Conclusions: The prognosis of LA-NSCLC patients with PD-L1 positive and no-EGFR mutation receiving concurrent chemoradiation has a trend of poor prognosis. A larger sample size study is warranted to explore the prognostic value of PD-L1 expression in inoperable LA-NSCLC patients and to further explore the effect of immunotherapy on patients with different PD-L1 expression levels.
