RESUMO
Tendinopathies are chronic diseases of an unknown etiology and associated with inflammation. Mesenchymal stem cells (MSCs) have emerged as a viable therapeutic option to combat the pathological progression of tendinopathies, not only because of their potential for multidirectional differentiation and self-renewal, but also their excellent immunomodulatory properties. The immunomodulatory effects of MSCs are increasingly being recognized as playing a crucial role in the treatment of tendinopathies, with MSCs being pivotal in regulating the inflammatory microenvironment by modulating the immune response, ultimately contributing to improved tissue repair. This review will discuss the current knowledge regarding the application of MSCs in tendinopathy treatments through the modulation of the immune response.

Objective:To evaluate the role of O-sialoglycoprotein endopeptidase (OSGEP) in hepatic ischemia-reperfusion injury (HIRI) and the relationship with oxidative stress in mice.Methods:Experiment Ⅰ Twenty-four SPF healthy male C57BL/6 mice, 12 wild-type and 12 OSGEP knockdown, aged 6-8 weeks, weighing 18-22 g, were divided into 4 groups ( n=6 each) by the random number table method: wild-type shamoperation group (Sham group), wild-type HIRI group (HIRI group), OSGEP knockdown+ sham operation group (Sham+ KD group) and OSGEP knockdown+ HIRI group (HIRI+ KD group). Ischemia-reperfusion model was prepared by blocking the hepatic artery and portal vein for 60 min followed by reperfusion in anesthetized animals, the blood vessels were only exposed without occlusion in Sham group and Sham+ KD group, and the blood vessels were clamped for 60 min followed by reperfusion in HIRI group and HIRI+ KD group. The mice were sacrificed after 6-h reperfusion to extract liver tissue samples for microscopic examination of histopathological changes (with an optical microscope after HE staining) which were evaluated using Suzuki score and for determination of the serum concentrations of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), level of reactive oxygen species (ROS) (using the DCFH-DA fluorescent probe method), contents of malondialdehyde (MDA) and glutathione(GSH) in liver tissues (using a colorimetric method) and expression of OSGEP (using Western blot). Experiment Ⅱ The well-growing AML12 cells were divided into 4 groups ( n=30 each) using a random number table method: control group (C group), oxygen-glucose deprivation/restoration (OGD/R) group, OGD/R+ OSGEP knockdown group (OGD/R+ KD group), and OGD/R+ OSGEP knockdown negative control group (OGD/R+ NC group). Group C was cultured under normal conditions. Group OGD/R was subjected to O 2-glucose deprivation for 6 h followed by restoration of O 2-glucose supply for 24 h in OGD/R group. In OGD/R+ KD group, stable transfection of AML12 cells with OSGEP knockdown was performed prior to the experiment, and the other procedures were the same as those previously described. The cell survival rate was measured by the CCK-8 assay, the release of lactate dehydrogenase (LDH) was measured, the DCFH-DA method was used to detect the levels of ROS, and the contents of MDA and GSH were determined using a colorimetric method. Results:Experiment Ⅰ Compared with Sham group, the expression of OSGEP was significantly down-regulated, the serum concentrations of AST and ALT, Suzuki score, levels of ROS and content of MDA were increased, and the GSH content was decreased in HIRI group ( P<0.05), and no significant change was found in each parameter in Sham+ KD group ( P>0.05). Compared with HIRI group, the serum concentrations of AST and ALT, Suzuki score, levels of ROS and content of MDA were significantly increased, and the GSH content was decreased in HIRI+ KD group ( P<0.05). Experiment Ⅱ Compared with group C, the expression of OSGEP was significantly down-regulated, the cell survival rate and GSH content were decreased, and the release of LDH, levels of ROS and content of MDA were increased in group OGD/R ( P<0.05). Compared with OGD/R group, the cell survival rate and GSH content were significantly decreased, and the release of LDH, levels of ROS and content of MDA were increased in OGD/R+ KD group ( P<0.05), and no significant change was found in each parameter in OGD/R+ NC group ( P>0.05). Conclusions:OSGEP plays an endogenous protective role in HIRI by inhibiting oxidative stress in mice.
RESUMO
Objective:To explore the clinical features of programmed cell death-1 (PD-1) inhibitor-associated hypophysitis and improve the understanding of the disease.Methods:For the present retrospective case series study, the clinical data of patients with PD-1 inhibitor-associated hypophysitis who were treated at the Affiliated Hospital of Hebei University and the 3rd Hospital of Hebei Medical University from January 2020 to May 2023 were collected for analysis of clinical manifestations and prognosis.Results:Fifteen cases of PD-1 inhibitor-induced hypophysitis were included, with 13 males and 2 females. The mean age of onset was (62.1±7.5) years, and the median time of onset was 6.5 (4.7, 11.6) cycles of PD-1 inhibitor. At diagnosis, 14 patients complained of gastrointestinal symptoms, and 12 patients complained of fatigue. There were 12, 1, 1, 5, and 1 cases of hyponatremia, hypokalemia, hypoglycemia, hypotension, and fever, respectively. Secondary adrenocortical insufficiency occurred in all cases. Moreover, four patients had secondary hypothyroidism, and two patients had secondary hypogonadism. Posterior pituitary hypofunction was not found. Pituitary MRI showed one case each of vacuolar sella turcica, pituitary cystic lesion, pituitary stalk slightly shifted to the left, high metabolism in the sella turcica, and pituitary abnormal signal, while no abnormalities were found in 11 cases. The follow-up time was (47.66±11.93) weeks. At the last follow-up, one patient′s serum levels of adrenocorticotropic hormone and cortisol returned to normal.Conclusions:Hypophysitis associated with PD-1 inhibitors occurs later, and gastrointestinal symptoms and fatigue are the most common clinical manifestations. PD-1 inhibitor-associated hypophysitis mainly manifests as adrenocortical hypofunction, and some cases manifest as hypothyroidism and hypogonadism. In addition, patients with PD-1 inhibitor-associated hypophysitis show no obvious imaging changes in the pituitary gland.

RESUMO
Objective:To compare the efficacy of fractional CO 2 laser combined with topical delivery of fluorouracil versus compound betamethasone injections in the treatment of vitiligo. Methods:Clinical data were collected from 94 patients with localized, non-segmental, and stable vitiligo, who received fractional CO 2 laser combined with drug delivery at the Cosmetological Center, Xijing Hospital, Air Force Medical University from October 2018 to May 2023, and were retrospectively analyzed. Among them, there were 40 cases in the fractional CO 2 laser combined with fluorouracil injection group, and 54 cases in the fractional CO 2 laser combined with compound betamethasone injection group. All the patients received the above treatment once a month for 5 sessions. A 4-level grading scale was used to evaluate the pigmentation improvement, and the clinical efficacy and safety of the two therapeutic regimens were compared. Comparisons between groups were performed using chi-square test, Fisher′s exact test, and t test. Results:In the fractional CO 2 laser combined with fluorouracil injection group, there were 22 males and 18 females, their ages were 21.95 ± 12.88 years, and the disease duration was 25.46 ± 11.42 months; in the fractional CO 2 laser combined with compound betamethasone injection group, there were 36 males and 18 females, their ages were 22.26 ± 8.79 years, and the disease duration was 26.51 ± 12.81 months. One month after the first treatment, no significant difference was observed in the efficacy between the two groups ( χ2 = 1.39, P = 0.238). One month after the fifth treatment, 2 (5.0%) patients showed an excellent response, 4 (10.0%) showed a good response, 12 (30.0%) showed a mild response, and 22 (55.0%) showed a poor response in the fractional CO 2 laser combined with fluorouracil injection group; in the fractional CO 2 laser combined with compound betamethasone injection group, 8 (14.8%) patients showed a good response, 8 (14.8%) showed a mild response, and 38 (70.4%) showed a poor response; there was no significant difference in the efficacy between the two groups after 5 sessions of treatment ( χ2 = 2.35, P = 0.125). After either 1 or 5 sessions of treatment, there were no significant differences in the efficacy for lesions on the face and neck, trunk and limbs, hands and feet between the two therapeutic regimens (all P > 0.05). Comparisons of the efficacy for skin lesions on different body sites showed that one session of the fractional CO 2 laser combined with fluorouracil injection was more effective for the treatment of skin lesions on the face and neck compared with those on the hands and feet ( P = 0.039) ; after 5 sessions of treatment, the two therapeutic regimens both showed better efficacy for facial skin lesions compared with hand and foot skin lesions ( P = 0.005, 0.049). There was no significant difference in the occurrence of adverse reactions such as pigmentation, infection and scarring between the two groups. Conclusion:The fractional CO 2 laser combined with topical delivery of fluorouracil and compound betamethasone injections showed similar efficacy and safety in the treatment of vitiligo, and both can be used as treatment options for vitiligo.

RESUMO
Objective:To evaluate the efficacy and safety of a gastric bypass stent system for weight loss and obesity-associated metabolic parameters.Methods:A sub-analysis of a multicenter randomized control trial was conducted on data of 14 obese patients who were implanted the gastric bypass stent system under endoscopy in Beijing Friendship Hospital, Capital Medical University from March 2021 to October 2022. The device was removed after 12 weeks and the patients were followed up for 36 weeks. Outcomes included changes in excess weight loss (EWL), total weight loss (TWL), insulin resistance, liver enzymes, lipids and uric acid at 12, 24 and 36 weeks, and the safety of the device.Results:Among the 14 patients, there were 9 males and 5 females, aged 34.3±7.4 years, with an initial body weight of 104.8±13.9 kg. Stents were removed in advance in 2 patients because of intolerable adverse reactions of the digestive tract. The remaining 12 patients completed follow-up, and their EWL was 34.4%±25.5% at 12 weeks, 39.1%±37.5% at 24 weeks, and 27.3%±40.8% at 36 weeks. TWL was 8.7%±6.2%, 10.1%±10.2% and 8.3%±13.8%, respectively. The levels of homeostasis model assessment of insulin resistance (HOMA-IR) at 12 weeks (4.81±3.71, P=0.022), 24 weeks (4.17±2.77, P=0.002) and 36 weeks (4.66±3.58, P=0.016) were statistically significant compared with baseline (7.03±3.59). The levels of alanine aminotransferase (ALT) were 48 (21-124) U/L, 39 (14-96) U/L, 27 (10-86) U/L and 32 (16-113) U/L at baseline, 12 weeks, 24 weeks and 36 weeks, respectively, and the changes of ALT were statistically significant at 24 weeks and 36 weeks ( P=0.009, P=0.026 compared with baseline). The levels of aspartate aminotransferase (AST) were 30 (20-62) U/L, 24 (15-72) U/L, 22 (11-56) U/L and 26 (13-74) U/L at baseline, 12 weeks, 24 weeks and 36 weeks, respectively, and the change of AST was significant at 24 weeks ( P=0.018 compared with baseline). However, the changes of uric acid and serum lipid were not statistically significant ( P>0.05). The only severe adverse event was esophageal mucosal laceration during the process of explantation, which was successfully treated with endoscopic clips. There was no device migration, acute pancreatitis or hepatic abscess. Conclusion:The gastric bypass stent system, relatively safe, has a good short-term weight loss effect and improves insulin resistance and liver enzymes.
RESUMO
Objective:To review and analyze clinical data of patients with invasive pulmonary aspergillosis and mucormycosis, and to explore the surgical indication.Methods:Clinical data of 10 patients with invasive pulmonary aspergillosis and mucormycosis were analyzed retrospectively from March 2018 to November 2022 in our hospital, Department of Thoracic Surgery.Results:The age of children varied from 2.58 years old to 16.00 years old and 6 children were males while 4 females. Five patients suffer from invasive pulmonary aspergillosis. Five patients suffer from invasive pulmonary mucormycosis. The operative indication of 7 patients was the risk of massive bleeding in the airway. The surgical indication for two patients is to control infection and continue treating malignant tumors. One patient chose surgical treatment because the infection could not be cured after long-term antifungal treatment but the focus was limited. Two patients died of sudden acute hemoptysis before operation, the prognosis of 8 patients undergoing surgical treatment was good.Conclusion:The lethal rate of invasive pulmonary aspergillosis and mucormycosis is very high. Antifungal drug treatment combined with timely surgical treatment can save patients lives.
RESUMO
Uric acid (UA), the final product of human purine metabolism, can cause hyperuricemia (HUA) when excessively accumulated. HUA is closely linked to chronic kidney diseases (CKD) and is considered an independent risk factor. Hyperuricemic nephropathy, a form of CKD induced by HUA, has seen significant advances in understanding through research into the pathogenic roles of uric acid and the development of HUA animal models. Although progress has been made in understanding the pathophysiological mechanisms by which UA induces CKD, much remains to be learned about its pathological molecular mechanisms. New approaches in animal modeling or the selection of model animals may potentially lead to significant breakthroughs in research on hyperuricemia as well as related CKD. This paper reviews the research progress on the molecular mechanisms of hyperuricemic nephropathy, focusing on oxidative stress, inflammation, autophagy, fibrosis, and gut microbiota. Oxidative stress is induced by uric acid intracellularly through xanthine oxidase, NADPH oxidases, and mitochondria, leading to cellular damage. In terms of inflammation, uric acid crystals can activate the NLRP3 inflammasome, triggering an inflammatory cascade. The role of free uric acid as a pro-inflammatory agent, however, remains controversial. Depending on the study conducted, autophagy has been found to either alleviate or exacerbate inflammation induced by uric acid. Fibrosis, particularly through epithelial-mesenchymal transition (EMT), is a major mechanism by which uric acid causes glomerulosclerosis and tubulointerstitial fibrosis. Extensive research has explored various signaling pathways involved in uric acid-induced EMT. Beneficial gut microbiota protect the kidneys by synthesizing short-chain fatty acids, reducing urea’s enterohepatic circulation, and decreasing uric acid production. This paper aims to enhance understanding of the complex relationships between HUA and CKD, serving as a reference for further research and new drug development.
RESUMO
【Objective】 To investigate the development of adaptability in children aged 2 - 6, and to explore its influencing factors, so as to provide reference for promoting the development of adaptability in young children. 【Methods】 Data were from the National Nutrition and Health Systematic Survey for Children in China, and 3 319 children aged 2 - 6 and their parents from 28 sites across 14 provinces were recruited in this study.The Development Scale for Children Aged 0 - 6 years (WS/T 580-2017) was used to measure the developmental quotient of children′s adaptive ability, and a survey questionnaire was used to collect relevant information about children and their parents. 【Results】 Among 3 319 children aged 2 - 6, the proportion of slightly low or low level of adaptability, moderate adaptability development, good and excellent adaptability development was 7.68%,66.25% and 26.06%, respectively.The proportion of children aged 5 - 6 with good and excellent adaptability was lower in 3-year-old and 4-year-old groups (χ2=59.29, P<0.05).Multiple stepwise linear regression showed that children′s gender (β=0.06), gestational age of birth (β=-0.05), only child (β=-0.04), left-behind child (β=-0.04), the main caregiver (β=-0.06), and the education level of parents (β=0.09, 0.10), whether parents actively pay attention to children′s emotions (β=-0.06) and whether children play with homemade toys (β=-0.04) were the influencing factors of children′s adaptive development quotient.Girls, full-term children, only children, non-left-behind children, children with parents as main caregivers, parents with a high level of education, parents who often take the initiative to pay attention to children′s emotions, and children who play with homemade toys had a higher level of adaptability development quotient. 【Conclusions】 The development level of adaptability in children aged 2 - 6 in China is mostly above the average level and is related to multiple factors.Targeted intervention work can be carried out on relevant factors in order to promote the development of children′s adaptability.
RESUMO
ObjectiveTo observe the clinical efficacy and safety of Chinese herbal enema combined with fumigation as adjunctive therapy for non-dialysis chronic kidney disease （CKD） patients of stage 3-5 with spleen-kidney yang deficiency and turbid toxin blood stasis pattern. MethodsA total of 120 non-dialysis CKD，patients of stage 3-5 with spleen-kidney yang deficiency and turbid toxin blood stasis pattern were randomly divided into treatment group and control group， with 60 cases in each group. The control group received conventional western medical treatment， while the treatment group additionally received Chinese herbal enema combined with fumigation， with enema and fumigation performed alternately， once every other day， three times a week. The treatment course for both groups was 4 weeks. The levels of serum creatinine （Scr）， estimated glomerular filtration rate （eGFR）， and the total score of traditional Chinese medicine symptoms were compared before and after treatment in both groups. The efficacy of traditional Chinese medicine symptoms and clinical efficacy were compared between the two groups after treatment. Adverse reactions in both groups were observed during the treatment period. ResultsThe total score of traditional Chinese medicine symptoms was significantly reduced after treatment in both groups （P＜0.01）. Compared to the control group after treatment， the treatment group showed significant decreases in Scr and the total score of traditional Chinese medicine symptoms， and a significant increase in eGFR （P＜0.05）. The total effective rate of traditional Chinese medicine symptoms in the treatment group （96.67%） was higher than that in the control group （46.67%， P＜0.01）， as well as the total effective rate of clinical efficacy in the treatment group （75.00%） versus that in the control group （28.33%， P＜0.01）. During the treatment period， the vital signs of patients in both groups remained stable， and there were no significant abnormalities in blood routine， urine routine， stool routine， liver function indicators， and electrocardiogram after treatment. ConclusionChinese herbal enema combined with fumigation as adjunctive therapy can significantly alleviate clinical symptoms， improve renal function， and demonstrate good safety for non-dialysis CKD patients of stage 3-5 with spleen-kidney yang deficiency and turbid toxin blood stasis pattern.
RESUMO
Edema is one of the typical symptoms of nephrotic syndrome， and symptomatic diuretics is mainly used in clinical practice but with unstable effect. This paper reported a case of refractory edema of nephrotic syndrome treated by acupuncture. The patient was mainly manifested as edema in both lower limbs， which were sunken when pressed and difficult to recover. After symptomatic treatment with western medicine， the effect was not obvious. In traditional Chinese medicine， this patient was diagnosed as spleen-kidney depletion and water-dampness internal accumulation syndrome. Based on the principle of “when swelling is below the waist， urination should be induced” in ZHANG Zhongjing's Essentials from the Golden Cabinet （《金匮要略》）， it is recommended to puncture at Shuidao （ST 28） and Shuifen （CV 9） to promote urination， at Sanyinjiao （SP 6）， Lougu （SP 7）， Yinlingquan （SP 9） and Zusanli （ST 36） to fortify the spleen and boost the kidneys and treat the root and branch simultaneously. After 3-day treatment， urine becomes smooth， and the edema of both lower limbs disappeared.
RESUMO
【Objective】 To describe the distribution characteristics of knee and ankle joint range of motion and muscle atrophy related indexes in patients with Kashin-Beck disease (KBD) in Shaanxi Province so as to explore the correlation of knee and ankle joint range of motion (ROM) with muscle atrophy indexes and provide reference for clinical characteristics analysis of KBD patients. 【Methods】 To investigate the registered KBD patients from KBD areas in Shaanxi Province, we measured the general demographic data of the patients were collected and the ROM of the knee joint (flexion and extension), the ankle joint (dorsiflexion and plantar flexion), and the muscle atrophy related indexes such as the upper arm circumference, thigh circumference, calf circumference and grip strength. According to the population characteristics, i.e., gender, age, body mass index (BMI) and KBD grade, the median and quartile of joint ROM and muscle atrophy of KBD patients were reported, and then the differences in each index among different groups were analyzed. Partial correlation analysis was used to explore the correlation between indicators after controlling for variables such as gender, age and BMI. 【Results】 A total of 480 patients with KBD were investigated in this study, who consisted of 249 (51.9%) males and 231 (48.1%) females, with an average age of (63.10±7.32) years and an average BMI of (23.49±8.90) kg/m2. The knee flexion ROM, knee extension ROM, ankle dorsiflexion ROM and ankle plantar flexion ROM were [105.0 (95.0, 120.0)] °, [0.0 (-15.0, 0.0)] °, [5.0 (0.0, 15.0)] ° and [20.0 (15.0, 30.0)] °, respectively, in KBD patients in Shaanxi Province. The left thigh circumference, right thigh circumference, left calf circumference, right calf circumference, and upper arm circumference were [43.0 (40.0, 47.0)] cm, [43.0 (39.0, 47.0)] cm, [29.0 (27.0, 32.0)] cm, [29.5 (27.0, 32.0)] cm, [27.0 (25.0, 30.0)] cm, respectively. The left hand grip strength and right hand grip strength were [13.4 (9.5, 18.4)] kg and [13.9 (9.8, 18.2)] kg, respectively. With the increase of age, the extension range of the left and right knee joints of KBD patients showed a decreasing trend (H=31.499, 31.847; all P<0.001). The range of motion of bilateral knee flexion was higher in the normal BMI group than in the overweight or obese group, with statistically significant differences (H=7.753, 12.333; P=0.021, 0.002). The knee flexion, thigh circumference, and calf circumference of the left and right sides showed a decreasing trend under different KBD grades (H=14.345, 17.256, 8.000, 8.462, 8.558, 9.633; all P<0.05). Correlation analysis showed that knee flexion ROM was positively correlated with thigh circumference, calf circumference, and grip strength in patients with KBD (all P<0.05). There was a positive correlation between knee extension ROM and thigh circumference in patients with KBD (P<0.01). 【Conclusion】 The impaired joint ROM and muscle atrophy are serious in KBD patients in Shaanxi Province, and there is a correlation between joint motion and muscle atrophy.

MethodSeventy-five SD rats were randomized into normal， model， low-， medium-， and high-dose （4.37， 8.73， 17.46 g·kg-1， respectively） modified Shengjiangsan， and irbesartan （0.014 g·kg-1） groups， with 10 rats in each group. Rats were administrated with corresponding doses of medications or distilled water by gavage， once a day， for 8 consecutive weeks. After the last administration， the levels of glucose （GLU） in the blood， 24-hour urinary protein （24 h-UTP）， and superoxide dismutase （SOD）， malondialdehyde （MDA）， and glutathione peroxidase （GSH-Px） in the renal tissue were measured. Hematoxylin-eosin staining， periodic acid-Schiff staining， and transmission electron microscopy were employed to observe the pathological changes in rat kidneys. Immunohistochemistry was employed to measure the expression levels of nephrin， podocin， glucose-regulated protein 78 （GRP78）， C/EBP homologous protein （CHOP）， and activating transcription factor 4 （ATF4） in the kidneys of rats. Western blot was employed to measure the protein levels of silent information regulator 1 （Sirt1）， phosphorylated （p）-protein kinase RNA-like endoplasmic reticulum kinase （PERK）， and p-eukaryotic translation initiation factor 2 alpha （eIF2α） in rat kidneys. ResultCompared with the normal group， the modeling caused pathological damage to the kidneys， elevated the levels of GLU and 24 h-UTP （P<0.05）， up-regulated the protein levels of GRP78， CHOP， ATF4， p-PERK， and p-eIF2α （P<0.05）， and down-regulated the protein level of Sirt1 （P<0.05） in rat kidneys. Compared with the model group， modified Shengjiangsan and irbesartan lowered the GLU and 24 h-UTP levels （P<0.05）， alleviated the pathological damage in the renal tissue， down-regulated the protein levels of GRP78， CHOP， ATF4， p-PERK， and p-eIF2α （P<0.05）， and up-regulated the protein level of Sirt1 （P<0.05）. ConclusionModified Shengjiangsan up-regulates Sirt1 expression and inhibits phosphorylation of proteins in the PERK/eIF2α pathway to reduce ER stress and oxidative stress in the renal tissue， thus alleviating the pathological damage in the renal tissue and reducing urinary protein in DN rats.
RESUMO
Objective @#To investigate the effect of miR-141-3p on LPS induced A549 cell injury by targeting high mobility group protein 1 (HMGB1) ．@*Methods @#A549 cells derived from type Ⅱ alveolar epithelial cells were taken as the study object，miR-141-3p mimics，mimics NC，HMGB1 gene overexpression plasmid (pcDNA3. 1-HMGB1) and empty Vector were transfected into A549 cells respectively or co-transfected，then 10 μg / ml LPS was used for 24 h．Cell proliferation activity was detected by cell counting kit-8 ( CCK-8) ．The activity of lactate dehydrogenase ( LDH) in the supernatant of cell culture was detected by colorimetry．The apoptosis level of each group was detec- ted by flow cytometry．The levels of interleukin (IL) -1 β , IL-6 and tumor necrosis factor α (TNF-α) were detected by enzyme-linked immunosorbent assay (Elisa) ．Dual luciferase reporter gene assay verified the targeted regulatory relationship between miR-141-3p and HMGB1 . @*Results @#After treatment with LPS ，the proliferative activity of A549 cells and the expression level of miR-141-3p decreased ( P ＜0. 05 ) ，the apoptosis rate increased ( P < 0. 05) ，the levels of IL-1 β , IL-6，TNF-α and the activity of LDH in supernatant increased (P＜0. 05) ．Overex- pression of miR-141-3p increased the proliferation activity of A549 cells treated with LPS (P ＜0. 05 ) ，and de- creased the apoptosis rate and the levels of IL-1 β , IL-6，TNF-α in cells and LDH activity in supernatant (P < 0. 05) ．However，overexpression of HMGB1 gene could reverse the ameliorative effect of miR-141-3p on LPS-in- duced A549 cell injury．Dual luciferase reporter gene experiment confirmed that HMGB1 was the downstream target gene of miR-141-3p．@*Conclusion @# miR-141-3p can inhibit LPS-induced apoptosis，reduce the expression level of inflammatory factors，and improve the damage of A549 cells，which may be related to the targeted regulation of HMGB1 expression.
RESUMO
ObjectiveTo evaluate the measles surveillance system （MSS） in Jiading District， Shanghai from 2020 to 2022， and to provide evidence for the elimination of measles. MethodsDescriptive methods were used to analyze the MSS data and confirmed measles cases from 2020 to 2022 and to evaluate MSS performance indicators. ResultsA total of 120 suspected cases were reported through the MSS from 2020 to 2022， of which 12 were classified as measles， 9 as rubella， and 99 as non-measles /rubella. The incidence of reported non-measles /rubella was 1.44 per 100 000 population in 2020， 2.01 per 100 000 population in 2021， and 1.99 per 100 000 population in 2022. The rates of complete investigation within 48 hours， blood samples and etiology collection， timely delivery， and timely reporting were all 100%. Among the 12 confirmed measles cases from 2020 to 2022， seven routine immunization subjects completed the required doses of measles vaccines， while two out five adult cases had a history of measles vaccine-related immunization. The confirmed cases comprised six with fever accompanied by rash， five with rash alone， and one with fever alone. ConclusionThe MSS results in Jiading District， Shanghai are overall satisfactory. However， there is a need to improve sensitivity， especially in detecting and reporting cases with atypical symptoms. It is imperative to maintain high vaccination coverage for age-appropriate children， promote supplementary immunization activities， and elevate the overall immunity of the entire population.
