ObjectiveTo explore the effect of home exercise on pain, function and quality of life after operation for rotator cuff injury. MethodsFrom June, 2023 to June, 2024, 45 patients after operation for rotator cuff injury were selected from Xuzhou Rehabilitation Hospital Affiliated to Xuzhou Medical University and Xuzhou Central Hospital, and randomly divided into conventional group (n = 15), home-based group (n = 15) and combined group (n = 15). The conventional group received an eight-week routine rehabilitation program in hospital, the home-based group received an eight-week home exercise prescription training, and the combined group first received four weeks of routine rehabilitation in hospital, and followed by four weeks of home exercise prescription training. They were assessed with Visual Analogue Scale for pain (VAS), University of California at Los Angeles shoulder rating scale (UCLA), Constant-Murley Score (CMS), range of motion (ROM) of shoulder, and the Short-form of Health Survey-36 (SF-36) before treatment, and four and eight weeks after treatment. ResultsVAS scores decreased in all the three groups four and eight weeks after treatment (Z > 2.964, P < 0.001), which was the most in the home-based group four weeks after treatment (|Z| > 2.531, P < 0.05). The main effect of time was significant in scores of UCLA, CMS, and physical health and mental health of SF-36 (F > 498.102, P < 0.001), which improved after treatment (P < 0.001). The main effect of group was significant in score of mental health of SF-36 (F = 7.408, P = 0.002), which was the most in the home-based group four and eight weeks after treatment (P < 0.01). The interaction was significant in score of physical health of SF-36 (F = 10.138, P < 0.001), which was the least in the home-based group four weeks after treatment (P < 0.05). The main effect of time was significant in every direction of ROM, which improved after treatment (P < 0.001). The interaction was significant in ROM of abduction and external rotation (F > 4.059, P < 0.01), and almost significant in ROM of flexion (F = 2.412, P = 0.055). However, ROM of flexion was less in the home-based group than in the combined group four weeks after treatment (P = 0.047), which was less in the home-based group than in the conventional group eight weeks after treatment (P = 0.042); ROM of abduction was the least in the home-based group four weeks after treatment (P < 0.01), which was less in the home-based group than in the combined group eight weeks after treatment (P = 0.046); ROM of external rotation was less in the home-based group than in the combined group four weeks after treatment (P = 0.022). ConclusionHome exercise is effective on pain, function and quality of life in patients after operation for rotator cuff injury. There are benefits with both home exercise and institution-based rehabilitation, and almost the same in a whole eight weeks after treatment.

Objective To investigate the differences in chemical components and bacterial diversity on the surface of Citrus reticulata at various drying temperatures(35、45、55、65℃).Methods At various drying temperatures,Citrus reticulata from Dahongpao produced in Chongqing Wanzhou was dried.By using HPLC,the effects of various drying temperatures on the hesperidin,hesperidin,and kaempferin concentrations in Citrus reticulata were examined.By using GC-MS,the effects of various drying temperatures on the Citrus reticulata volatile components were examined.The differences in bacterial population structure on the surface of Citrus reticulata at various drying temperatures were examined using high throughput sequencing.Results The higher the temperature,the quicker Citrus reticulata will dry.The amount of hesperidin and hesperidin in Citrus reticulata was not significantly affected by different drying temperatures.The amount of Citrus reticulata increased as the drying temperature rose.GC-MS analysis identified 15 main components in Citrus reticulata,and the proportion of some volatile aroma components decreased with the increase of drying temperature;Such as laurylene,linalool,carvol α-Orange aldehyde,etc.With the increase of drying temperature,the dominant bacteria of Proteobacteria has an upward trend.At the same time,the dominant bacteria of Halomonas and Porphyromonas have changed to Metallobacterium.Conclusion If the drying temperature is too high,the volatile components in the dried Citrus reticulata may be transformed or destroyed due to the instability of heating.The difference of the bacterial flora on the surface of Citrus reticulata at different drying temperatures may cause the change of the volatile components in the later aging process.Considering the quality of dried tangerine peel,low temperature and hot air drying is the better drying method.

Objective To observe the effect of Tongxie Yaofang-containing serum on the cell cycle and apoptosis of colon cancer HCT116 cells,and to explore its possible biological mechanism.Methods Colon cancer HCT116 cells were divided into blank group and Tongxie Yaofang-containing serum group with different concentrations.Cell proliferation and activity detection-8(CCK8)was used to detect the effect of each group on the viability of HCT116 cells at 24,48 and 72 h;Flow cytometry was used to detect the apoptosis and cycle arrest of HCT116 cells induced by different concentrations of Tongxie Yaofang-containing serum;Western blot was used to detect the protein expression level of Cell Cycle Regulatory Protein P21(P21),Cyclin B1,cyclin-dependent protein kinases-1(CDK1),B-lymphoma-2(Bcl-2),Bcl-2-related X protein(Bax),phosphatidylinositol-3-kinase(PI3K),phosphorylated phosphatidylinositol-3-kinase(p-PI3K),protein kinase B(Akt)and phosphorylated protein kinase B(p-Akt)after different concentrations of Tongxie Yaofang-containing serum intervention.Results CCK8 showed that compared with the 10%blank group,10%Tongxie Yaofang-containing serum had a significant inhibitory effect on the viability of HCT116 cells only at 48 h(P<0.01);Compared with the 20%blank group,20%Tongxie Yaofang-containing serum could inhibit the viability of HCT116 cells at 48 and 72 h(P<0.01,P<0.05),and the increase of blank serum will not inhibit the viability of HCT116 cell,so 10%blank serum and 48 h were selected as the drug control and intervention time in the subsequent experiment.Flow Cytometry showed that,compared with the blank group,10%and 20%Tongxie Yaofang-containing serum could arrest HCT116 cell cycle in G2/M phase after 48 h of intervention(P<0.01),and induce HCT116 cell apoptosis.At the same time,Western blot showed that Tongxie Yaofang-containing serum could increase the expression of P21 and Bax to varying degrees,and reduces Cyclin B1,CDK1,Bcl-2,p-PI3K,p-Akt expression(P<0.05,P<0.01).Conclusion Tongxie Yaofang can inhibit the proliferation and induce apoptosis of colon cancer HCT116 cells,and its mechanism may be related to the inhibition of PI3K/Akt signaling pathway.

During the carcinoma transformation of colitis， the imbalance of “metabolic-immune interaction” resulted from abnormal energy and metabolic substrates flow and direction was the key process， which caused by intercellular metabolic competition. Based on traditional Chinese medicine （TCM） theory and clinical research， we found that “fire failing to warm earth” is the key pathogenesis of colon-cancer transformation. “Fire” was a synonym for TCM to understand the energy metabolism， combined modern medical research findings， we thought energy metabolism disorders was a microcosmic manifestation of the “fire decline”， while abnormal immune function was the biological basis of “earth deficiency”. The imbalance between “metabolism-immune interaction” and the “fire failing to warm earth” pathogenesis of colitis-cancer transformation demonstrated the different understanding of the same pathological mechanism between western medicine and TCM. For treatment， it could be effectivce to delay the transformation of colitis-cancer by synergistically regulated the energy metabolism - “replenish fire” and enhanced the immune function - “nourish earth”， which was called the methods of replenishing fire to nourish earth.

Pulmonary nodule is a key window for moving ahead the diagnosis and treatment of lung cancer. Traditional Chinese medicine （TCM） can delay the transformation of lung nodules into lung cancer， improve the prognosis of patients， effectively fill the treatment gap during the follow-up period of pulmonary nodules， and has been applied it in the whole cycle and multi-dimensional management of pulmonary nodules. This paper discussed the construction ideas and feasible paths of the whole process management diagnosis and treatment system of pulmonary nodules in TCM， proposed the diagnosis and treatment database of TCM for pulmonary nodules based on the social module of “family-community-hospital”. Through artificial intelligence， we can develop， improve and promote the multi-level and multi-modal “disease-symptom combination” risk prediction model and effectiveness evaluation system of pulmonary nodules. At the same time， the biological connotation of the prevention and treatment of pulmonary nodules by TCM is excavated， which provided empirical evidence for the construction of TCM diagnosis and treatment system， in order to further improve the quality and diagnosis and treatment level of the whole course management of pulmonary nodules.

Except for IgA nephropathy, membranous nephropathy (MN) is the most common primary glomerulonephritis in China. Neural epidermal growth factor-like 1 protein (NELL-1) has been currently considered as one of the target antigens for diagnosis of primary MN. Moyamoya syndrome is a syndrome with clinical and imaging manifestations of moyamoya disease and possible vascular stenosis. By far, primary MN complicated with moyamoya syndrome has not been reported internationally. The paper reports a case of NELL-1-related MN complicated with moyamoya syndrome and reviews relevant literature to provide evidence for clinical diagnosis and treatment.

ObjectiveTo explore the effect of Tongxie Yaofang on the immune microenvironment of colorectal cancer in mice under chronic stress and the underlying mechanism. MethodA total of 40 male SPF BABL/C mice were randomized into normal group， stress group， Tongxie Yaofang group （13.65 g·kg^-1）， and Tongxie Yaofang-stress group （13.65 g·kg^-1）， with 10 in each group. Chronic restraint stress was induced in mice and administration （ig） of Tongxie Yaofang began after 7 days of stress. On the 14^th day， forced swim and tail suspension tests were used to examine the behavioral changes of mice after stress and the subcutaneous colorectal tumor was implanted in each group of mice. The effect of this prescription on the body mass and tumor volume of mice was observed. After the last administration， mouse serum and tumor samples were collected. The content of T lymphocytes （CD3⁺， CD4⁺， CD8⁺， and CD4⁺/CD8⁺） in tumor was detected by immunohistochemistry and flow cytometry and levels of corticosterone （CORT） in peripheral blood， and interleukin （IL）-2， interferon-γ （IFN-γ）， IL-6， and IL-10 in the serum were determined by enzyme-linked immunosorbent assay （ELISA）. The protein expression of inhibitor of nuclear factor-κB（IκB） kinase α/β （IKKα/β）， nuclear factor-κB （NF-κB）α （IκBα）， NF-κB p65， and phosphorylated （p）-NF-κB p65 was measured by Western blot. ResultCompared with the normal group， the stress group had large tumor volume （P<0.05）， low content of CD3⁺， CD4⁺， and CD4⁺/CD8⁺ （P<0.05， P<0.01）， high content of CD8⁺， low content of T helper 1 （Th1）-secreted IFN-γ （P<0.05）， high content of T helper 2 （Th2）-secreted IL-10 （P<0.05） and CORT （P<0.05）， high protein expression of p-NF-κB p65， NF-κB p65， and IKKα/β （P<0.05）， and low protein expression of IκBα （P<0.05）. Compared with the normal group， the Tongxie Yaofang group showed slow tumor growth， high content of CD3⁺， CD4⁺， and CD4⁺/CD8⁺ （P<0.01）， low content of CD8⁺ （P<0.05）， high content of Th1-secreted IL-2 and IFN-γ （P<0.05）， low content of Th2-secreted IL-6 and IL-10 （P<0.05）， low content of CORT， low protein expression of p-NF-κB p65， NF-κB p65， and IKKα/β （P<0.05）， and high protein expression of IκBα （P<0.01）. Tongxie Yaofang-stress group demonstrated slower tumor growth， higher content of CD3⁺， CD4⁺， and CD4⁺/CD8⁺ （P<0.01）， smaller content of CD8⁺ （P<0.05）， higher content of IL-2 and IFN-γ （P<0.05）， lower content of IL-6， IL-10 （P<0.05）， and CORT （P<0.05）， lower protein expression of p-NF-κB p65， NF-κB p65， and IKKα/β （P<0.05，P<0.01）， and higher protein expression of IκBα （P<0.01） than the stress group. ConclusionTongxie Yaofang can delay the growth of colorectal cancer under chronic stress and alleviate the deterioration of the immune microenvironment， possibly by inhibiting NF-κB signaling pathway， regulating the function of T lymphocyte subsets， and thus suppressing the secretion of pro-inflammatory factors.

BACKGROUND: Nasal insertion is the preferred method for non-intubated patients in flexible bronchoscopy; however, the relatively narrow nasal cavity results in difficulties related to bronchoscope insertion. This study aimed to investigate whether pre-operative nasal probe tests could reduce the time to pass the glottis, improve the first-pass success rate and patients' tolerance, and reduce postoperative bleeding. METHODS: This three-arm prospective randomized controlled trial was conducted in a tertiary hospital between May and October 2020. Three hundred patients requiring diagnosis and treatment using flexible bronchoscopy were randomly allocated to three groups: control group, simple cotton bud detection group (CD group), and adrenaline + lidocaine detection group (AD group). The primary outcome was the time to pass the glottis. Secondary outcomes included the first-pass success rate, the patients' tolerance scores, and post-operative bleeding. One-way analysis of variance, Kruskal-Wallis H test, Chi-squared test, Fisher's exact test, and Bonferroni's multiple comparison tests were used in this study. RESULTS: In total, 189 men and 111 women were enrolled in this study, with a mean age of 55.72 ± 12.86 years. The insertion time was significantly shorter in the AD group than in the control group (18.00 s [12.00-26.50 s] vs . 24.00 s [14.50-45.50 s], P = 0.005). Both the AD (99% vs . 83%, χ2 = 15.62, P < 0.001) and CD groups (94% vs . 83%, χ2 = 5.94, P = 0.015) had a significantly higher first-pass success rate than the control group. Compared with the control group, post-operative bleeding (1% vs . 13%, χ2 = 11.06, P < 0.001) was significantly lower in the AD group. However, no significant difference was found in the patients' tolerance scores. CONCLUSIONS: Pre-operative nasal cavity probe tests especially with adrenaline and lidocaine during flexible bronchoscopy can significantly reduce the time to pass the glottis, improve the first-pass success rate, and reduce post-operative nasal bleeding. Pre-operative nasal probe tests are recommended as a time-saving procedure for patients undergoing flexible bronchoscopy.

Background Air quality health index (AQHI) has been widely used to quantify the health effects of multiple pollutants observed in population-based epidemiological studies, and can better reflect the widespread linear non-threshold between air pollution and health effects. Objective To explore an AQHI for pediatric respiratory diseases (AQHI_r) in Shanghai and evaluate its feasibility. Methods The daily numbers of hospital outpatient visits for pediatric respiratory diseases from 2015 to 2019 were obtained from five general hospitals in Xuhui, Baoshan, Hongkou, Jinshan, and Chongming Districts of Shanghai. Monitoring data on air pollutants (PM_2.5, PM₁₀, SO₂, NO₂, and O₃), air quality index (AQI), and meteorological variables (temperature, relative humidity, air pressure, and wind speed) were collected from five air quality monitoring sites nearest to selected hospitals. Time-series analysis using generalized additive model (GAM) was conducted to estimate the associations between respiratory-related pediatric outpatient visits and the concentrations of air pollutants. The sum of excess risk (ER) of hospital outpatient visits was used to construct AQHI_r. To assess the predictive power of AQHI_r, the associations of AQHI_r and AQI with the number of pediatric respiratory outpatient visits in three hospitals in Xuhui, Hongkou, and Chongming districts were compared. Results Air pollutants had various effects on respiratory diseases outpatient visits. PM_2.5, NO₂, and O₃ had most significant impacts on lag0 day and the associated ERs of hospital outpatient visits for each 10 μg·m⁻³ increase in pollutant concentration were 1.27% (95%CI: 0.88%-1.66%), 0.75% (95%CI: 0.40%-1.11%), and 0.36% (95%CI: 0.10%-0.62%), respectively. PM₁₀ and SO₂ had most significant impacts on lag3 day and the associated ERs of hospital outpatient visits for each 10 μg·m⁻³ increase in pollutant concentration were 0.81% (95%CI: 0.51%-1.12%) and 5.64% (95%CI: 3.37%-7.96%), respectively. There were significant effects of combinations of two pollutants among PM_2.5, PM₁₀, NO₂, SO₂, and O₃ except for PM₁₀+NO₂, SO₂+PM_2.5, and SO₂+NO₂ (P<0.05). According to the results of single-pollutant and two-pollutant models, PM_2.5, NO₂, SO₂, and O₃ were selected to construct AQHI_r. The comparison showed that for every interquartile range increase in AQHI_r, the ER for pediatric outpatient visits was higher than that for the value corresponding to AQI. Conclusion Air pollutants in Shanghai have an impact on the number of pediatric respiratory outpatient visits. The AQHI_r based on and outpatient visits for pediatric respiratory diseases can be a sensitive index to predict the effects of air pollution on children's respiratory health.
