Objective To explore the protective effect and mechanism of Jinyinqingre oral liquid on acute lung injury in-duced by lipopolysaccharide(LPS)in mice.Methods C57BL/6J mice were randomly divided into six groups according to the random number table method:blank control group,model control group,Jinyinqingre oral liquid low-dose group,Jinyinqingre oral liquid medium-dose group,Jinyinqingre oral liquid high-dose group,and dexamethasone group.Except for the blank control group,the other groups were injected with lipopolysac charide(LPS)(5 mg·kg-1)into the trachea to establish the acute lung injury model of mice,and the Jinyinqingre oral liquid low,medium,and high groups were continuously administered the drug by gavage for three days.After 24 h,lung tissue and bronchoalveolar lavage fluid(BALF)were collected from the six groups for follow-up detection.The pathological injury of lung tissue in each group was observed by HE staining.The total number of cells in BALF was detected.The to-tal protein content of BALF was detected by the BCA method.The contents of inflammatory cytokines TNF-α,IL-1β,IL-6,and IgM in BALF were detected by ELISA.The expression of NF-κB and NLRP3 proteins in lung tissues was detected by immunohistochemistry and Western blotting.Results Compared with model control group,Jinyinqingre oral liquid alleviated the pathological injury of lung tissue(P＜0.05),decreased the total cell count,total protein content and IgM expression in BALF(P＜0.01),and the expres-sion of inflammatory cytokines TNF-α,IL-6 and IL-1β in BALF was dreased(P＜0.05),the protein expressions of NF-κB and NL-RP3 in lung tissues was dreased(P＜0.05).Conclusion Jinyinqingre oral liquid attenuated the pathological injury,inflammatory exudation,and expression of inflammatory cytokines in LPS-induced lung injury in mice,and its mechanism may be through the reg-ulation of NF-κB/NLRP3 signaling pathway,providing a theoretical basis for its clinical application.

Abstract In recent years, the role of hyperopia reserve in the prevention and control of myopia among children and adolescents has gradually gained recognition and importance. Implementing more refined preventive measures based on hyperopia reserve to further advance the prevention frontiers is crucial for reversing the trend of focusing on treatment over prevention and achieving the national health strategy goal to reduce the myopia rate among children and adolescents. The paper introduces the concept of hyperopia reserve, the ability and the detection methods to predict the onset of myopia. At the same time, it also discusses the establishment and application of reference values for hyperopia reserve and proposes a classification based prevention and management strategy based on hyperopia reserve, aiming to provide reference ideas and directions for advancing myopia prevention.

Breast cancer is one of the most common cancers in women,but there is currently a lack of accurate prognos-tic assessment systems.The Naples Prognostic Score(NPS)is a prognostic prediction system that incorporates inflammatory and nutritional indicators.It has been proven to have important clinical utility in predicting the prognosis of patients with malignancies such as colon cancer,gallbladder cancer,endometrial cancer,and lung cancer.In recent years,research has found that NPS may be superior to TNMstaging in predicting the prognosis of breast cancer patients.It is an independent predictor of overall sur-vival(OS)and progression-free survival(PFS)in breast cancer patients.This suggests that NPS has great potential for applica-tion in predicting the prognosis of breast cancer.

Osteoporosis （OP） is a skeletal metabolic disease characterized by bone loss and destruction of bone microstructure. Changes in estrogen levels are not the only pathogenic factors for the occurrence and development of OP. MicroRNA （miRNA） plays an important regulatory role in cells. The complementary sequences of miRNA and targeted mRNA combine to inhibit the expression of targeted mRNA through post-transcriptional regulation， forming a complex regulatory network. Research suggests that miRNA is closely related to the occurrence and development of various diseases， including inflammatory diseases， metabolic diseases， and cancer. Targeted mRNA participates in post-transcriptional gene expression regulation in OP， mainly regulating the balance among bone construction， bone resorption， and osteoblast differentiation. Therefore， miRNA-based gene therapy is a rapidly developing disease treatment strategy. Traditional Chinese medicine can improve bone metabolism by intervening in miRNA differential expression to target and regulate osteogenic/osteoclast differentiation. This article summarized the targeting effects of miRNAs in physiological and developmental processes such as bone cell proliferation， differentiation， survival， and apoptosis， reviewed and classified their mechanisms of action and targets， and sorted out the current treatment methods of traditional Chinese medicine for preventing and treating OP and drugs that exert bone protective functions through miRNAs. This review is expected to provide theoretical reference and research guidance for future research on OP treatment by regulating miRNA.

Objective:To explore the effect of transcutaneous electrical nerve stimulation (TENS) on interleukin-33 (IL-33)/growth stimulation expressed gene 2 (ST2) signaling pathway in the dorsal root ganglia (DRGs) of rats modeling hyperalgesia (HP).Methods:This study consisted of two experiments. In the first, 30 Sprague-Dawley (SD) rats were randomly divided into a blank group, a Sham-HP group, an HP group, an antibody group and an inhibitor group, each of 6. HP was induced in all except the rats of the blank and Sham-HP groups by injecting carrageenan (Car) and prostaglandin E2 subcutaneously at the bottom of the left hind feet. The antibody and inhibitor groups were then given intrathecal injections of anti-ST2 antibody and a tumor necrosis factor α (TNF-α)-specific inhibitor, respectively. In the second experiment, 42 SD rats were randomly divided into a Sham-HP group, an HP group, a TENSⅠgroup, a TENS II group, a TENS I inhibitor group, a TENS II inhibitor group, and a Sham-TENS group, each of 6. All of the groups had HP induced as in experiment one. All of the rats except those in the Sham-HP, HP and Sham-TENS groups were then given TENS, and the TENS I and II inhibitor groups were offered intrathecal injection of TNF-α-specific inhibitors. Mechanical pain thresholds (MPTs) were documented 4h, 24h, 48h, 72h, 6d, 7d 4h, 7d 1h, and 7d after the Car injections. Western blotting was used to measure the protein expressions of IL-33, ST2 and TNF-α 6d after the Car injection in both experiments.Results:In experiment one, the average MPTs of the HP, antibody and inhibitor groups had decreased significantly 4 hours after the Car injection compared with the blank and Sham-HP groups. However, 7d 1h after the Car injection the value had increased significantly in the Sham-HP, antibody and inhibitor groups compared with the HP group, while the expressions of IL-33, ST2 and TNF-α had decreased significantly. In experiment two, by 4 hours after the Car injection, the average MPT of all the other groups had decreased significantly compared with the Sham-HP group. Moreover, by 7d 1h after the Car injection, the average MPTs of the groups receiving TENS had increased significantly, with significantly lower MPT in the TENS Ⅱ group than in group Ⅰ, on average. There was also significantly higher expression of IL-33, ST2 and TNF-α in group II. Compared with the TENS Ⅰ and Ⅱ groups, the average MPT was significantly higher in the TENS I and Ⅱ inhibitor groups, but IL-33, ST2 and TNF-α expression was lower.Conclusions:TENS can inhibit TNF-α expression, which influences the signals of the DRG IL-33/ST2 signaling pathway to reverse hyperalgesia. TENS combined with anti-TNF-α treatment is superior to TENS alone in treating hyperalgesia.

Objective:To compare the efficacy of Kirschner wire fixation combined with Suture-Bridge technique and simple Kirschner wire fixation in the treatment of old lateral malleolar avulsion fractures under all-inside arthroscopy.Methods:A retrospective cohort study was conducted to analyze the clinical data of 56 patients with old lateral malleolar avulsion fractures, admitted at Xuzhou Central Hospital from January 2018 to June 2022, including 32 males (32 feet) and 24 females (24 feet), aged 19-57 years [(35.2±11.1)years]. Twenty-five patients were treated with Kirschner wire fixation under all-inside arthroscopy (K-wire group), while the other 31 patients were treated with Kirschner wire fixation combined with Suture-Bridge technique under all-inside arthroscopy (K-wire combined with suture group). The surgical time, incision healing at 2 weeks after surgery, and fracture healing rate at 6 months after surgery of the two groups were detected. The American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores, and foot and ankle ability measure (FAAM) scores [including activities of daily living (ADL) scores and sports function (S) scores] of the two groups were assessed before surgery, at 3, 6 months after surgery, and at the last follow-up. The anterior drawer test was performed at 3, 6 months after surgery and at the last follow-up. The time of return to sports after surgery and complication rates were also recorded.Results:All the patients were followed up for 12-18 months [(14.2±2.2)months]. The surgical time in the K-wire combined with suture group was (56.3±12.5)minutes, longer than (41.1±8.2)minutes in the K-wire group ( P<0.01). The incisions in both groups were healed by first intention at 2 weeks after surgery. In the K-wire combined with suture group, all the fractures were healed at 6 months after surgery (100%), while in the K-wire group 22 patients (88%) obtained fracture healing ( P<0.05). There were no statistically significant differences in the AOFAS ankle-hindfoot scores, FAAM-ADL scores, or FAAM-S scores between the two groups preoperatively ( P>0.05). At 3, 6 months after surgery, and at the last follow-up, the AOFAS ankle-hindfoot scores in the K-wire combined with suture group were (89.7±3.4)points, (92.8±2.8)points, and (94.9±3.3)points respectively, higher than (87.4±4.4)points, (90.4±4.1)points, and (92.5±4.6)points in the K-wire group ( P<0.05); the FAAM-ADL scores and the FAAM-S scores in the K-wire combined with suture group were (90.1±3.5)points, (91.5±2.9)points, (92.8±3.0)points and (91.4±5.4)points, (92.8±5.0)points, (94.4±4.8)points respectively, higher than (86.8±5.0)points, (88.7±3.8)points, (90.3±3.7)points and (88.0±5.3)points, (89.5±4.8)points, (91.5±5.2)points ( P<0.05 or 0.01). The AOFAS ankle-hindfoot scores, FAAM-ADL scores, and FAAM-S scores at all postoperative time points were higher than those preoperatively and increased with the passage of the follow-up time ( P<0.01). The results of the anterior drawer test at all postoperative time points in the two groups were negative. The time of return to sports after surgery in the K-wire combined with suture group was (9.2±1.3)weeks, shorter than (10.3±1.5)weeks in the K-wire group ( P<0.01). One patient (3.2%) in the K-wire combined with suture group and 3 patients (12.0%) in the K-wire group had Kirschner wire loosening and withdrawal ( P>0.05). Neither of the two groups developed complications such as nerve or tendon injuries. Conclusion:Compared with simple Kirschner wire fixation under all-inside arthroscopy, Kirschner wire fixation combined with Suture-Bridge technique under all-inside arthroscopy achieves higher fracture healing rate, more obvious improvement in life quality and ankle function, as well as earlier return to sports in the treatment of old lateral malleolar avulsion fractures.

Objective To compare the differences in gut microbiota between cirrhosis patients receiving transjugular intrahepatic portosystemic shunt(TIPS)and those not,and explore the relationship between TIPS surgery and gut microbiota in order to provide new ideas for improving the prognosis of cirrhosis patients after TIPS surgery based on gut microbiota.Methods Those who had received TIPS surgery previously were assigned into the operation group,and those without the surgery served as the control group.Their stool samples were collected for 16S rRNA sequencing,and the correlation between gut microbiota and clinical indicators was analyzed.Results There were no significant differences in gender,age,body mass index(BMI),etiology and other baseline data between the 2 groups(P＞0.05),but obvious differences were observed in clinical serological indicators between them,including INR,APTT,RBC and PT counts,and HGB,ALP,ALB,total bilirubin(TBIL),and URE levels(P＜0.05).No statistical difference in alpha diversity was observed between the operation group and the control group(P＞0.05),but beta diversity was obviously different(P＜0.01),among which Bacteroides was increased in the operation group(P＜0.01)and Bifidobacterium was increased in the control group(P＜0.05).The function prediction analysis of gut microbiota showed that the metabolism of D-glutamine and D-glutamate(P＜0.05)and biosynthesis with secondary bile acids(P＜0.05)were up-regulated in the operation group compared with the control group.Correlation analysis between clinical indicators and flora indicated that TBIL and direct bilirubin(DBIL)were significantly correlated with the metabolic pathways of Bacteroides and Secondary bile acids biosynthesis.Conclusion Characteristic changes in gut microbiota are found in cirrhosis patients with and without TIPS surgery.Bacteroides may be involved in the regulation of metabolism of bile acids and thus increase bilirubin level.

Objective:To analyze the trends in refractive error and ocular biological parameters in elementary school students over 5 years, and to investigate the patterns of change before and after myopia onset.Methods:A cohort study was adopted.A total of 1 986 first-grade students from the Anyang Childhood Eye Study were enrolled in this cohort study and their right eye data were taken for analysis, including 1 126 boys and 860 girls.Every year, cycloplegic autorefraction was performed with 1% cyclopentolate eyedrops to obtain the spherical equivalent (SE).The axial length (AL), anterior chamber depth, lens thickness, mean corneal curvature (Km) and other parameters were obtained by ocular biometry.The lens refractive power (LP) was calculated using the Bennett formula.The subjects were assigned to persistent myopia group, non-myopia group and new onset myopia group.According to the age of myopia onset, the new onset myopia group was subdivided into the 8-, 9-, 10-, 11- and 12-year-old myopia groups to compare the differences in refractive error and ocular bioparameters among groups at different time points of follow-up.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Beijing Tongren Hospital, Capital Medical University (No.TRECKY2018-030).Written informed consent form was obtained from the guardians of each subject.Results:All children had a gradual SE drift toward myopia and a gradual increase in the AL with age, and there were significant differences in SE and AL between adjacent follow-up ages within the three groups (all at P<0.05).The earlier the onset of myopia, the higher the myopia SE and the longer the AL of the eye at the same follow-up age, the differences in SE between adjacent groups were statistically significant (all at P<0.05), and the differences in AL between adjacent groups at the follow-up age of 8 to 12 years were statistically significant (all at P<0.05).In the nonmyopia group, SE drifted toward emmetropia at a slow and steady rate of (-0.23±0.27)D/year, and AL also increased slowly and steadily at (0.18±0.13)mm/year.In the new onset myopia group, the changes in SE in the third, second, and first years before myopia onset were (-0.32±0.25), (-0.45±0.33), and (-0.98±0.44)D, and the increases in AL were (0.25±0.12), (0.32±0.15), and (0.48±0.19)mm, respectively.Both SE and AL change rates began to accelerate before myopia onset and slowed down after myopia onset, with statistically significant differences in the overall comparison of SE and AL change rates at different time intervals before and after myopia onset (all at P<0.001).The AL at myopia onset in boys was (24.11±0.70)mm, which was longer than (23.60±0.66)mm in girls ( t=159.71, P<0.01).LP decreased with age in all groups, with a faster rate before the age of 9 years and a slower rate after the age of 9 years.The mean decrease rate in LP was (-0.48±0.19), (-0.44±0.20), (-0.49±0.16), (-0.51±0.18), and (-0.48±0.19)D/year in the persistent myopia group and 8~11-year-old myopia group, respectively, which were significantly faster than -0.42±0.17 D/year in 12-year-old myopia group and (0.37±0.15)D/year in nonmyopia group (all at P<0.05).There was no statistically significant difference in Km among groups at different follow-up ages (all at P>0.05). Conclusions:The AL begins to grow at an accelerated rate 3 years before myopia onset, and the increase rate of the AL slows down after the onset of myopia, but it is still significantly faster than that of non-myopic children.In this process, the decrease in LP plays a compensatory role; there is no significant change in corneal curvature.The AL of males at the onset of myopia is longer than that of females at the same age.AL is an important indicator for the prevention and control of myopia.It is important to consider gender differences and to pay more attention to the growth rate when assessing AL.
