ObjectiveTo explore the effects of Jingui Shenqiwan （JSW） and Liuwei Dihuangwan （LDW） on the reproductive ability and brain function of normal mice and compare the actions of the two medications. MethodsSeven groups of female and male mice were divided at a ratio of 2∶1. Except for the control group， the other six groups were as follows： a group of both males and females receiving JSW （3.0 g·kg^-1）， a group of both males and females receiving LDW （4.5 g·kg^-1）， a group of males receiving water and females receiving JSW， a group of males receiving water while females receiving LDW， a group of females receiving water while males receiving JSW， and a group of females receiving water while males receiving LDW. Each group was administered the drug for 14 days and then caged together at a 2∶1 （female∶male） ratio to detect the number of pregnant mice and calculate the pregnancy rate. Pregnant mice continued receiving the drug until they naturally gave birth， which was followed by the observation of newborn mice， calculation of their average number， and the measurement of the offspring's preference for sugar water and neonatal recognition index. At the end of the experiment， the weights of the thymus and spleen were measured to calculate the organ coefficients， and mRNA or protein expression was analyzed in the brain and testes or ovaries. A 1% sucrose solution was used to examine the euphoria of their brain reward systems， while novel object recognition test （NOR） was applied to assess their memory capabilities. mRNA expression was detected using real-time quantitative polymerase chain reaction （Real-time PCR） assay， and protein expression was analyzed with Western blot. ResultsCompared with the control group， oral administration of JSW to both male and female mice for 14 days significantly increased the pregnancy rate of female mice on day 2 after being caged together （P<0.05）， while LDW showed a trend but no statistical significance. Additionally， compared with the control group， JSW could upregulate the gene expression of gonadotropin-releasing hormone （GnRH） in the thalamus， as well as reproductive stem cell factor （SCF） and tyrosine kinase receptor （c-Kit） in the testes and reproductive stem cell marker mouse vasa homologue （MVH） in the ovaries， upregulate the expression of proteins influencing neuronal functional activity， such as brain-derived neurotrophic factor （BDNF）， in hippocampal neurons （P<0.05）， and enhance sucrose preference in male mice （P<0.05）. Compared with the control group， JSW significantly increased sucrose preference and novel object recognition index in offspring mice （P<0.05）， which was related to the upregulation of hippocampal dopamine D1 receptor （D1R） and N-methyl-D-aspartate receptor （Nmdar） gene expression. Compared with the control group， both JSW and LDW could upregulate the protein expression of glucocorticoid receptor （GR）， BDNF， and tyrosine kinase receptor B （TrkB） in the hippocampus of offspring mice （P<0.05）. ConclusionJSW significantly enhances the reproductive ability of normal mice， which is not only related to the release of gonadotropin but also associated with its regulation of brain function. Additionally， JSW has a certain regulatory effect on the brain function of the offspring mice.

ObjectiveTo explore the effect of Shenge Bushen Capsules （SBC） on sexual development in normal 3-week-old mice. MethodsThe experiment consisted of two parts. In the first part， mice were divided into four groups： The control group and the low， medium， and high-dose SBC groups （234.7， 469.4， 938.7 mg·kg^-1， respectively）. In the second part， mice were divided into four groups： Control group， Pseudostellariae Radix polysaccharide （PRP） group， total flavonoids group， and SBC group， all receiving a dose of 469.4 mg·kg^-1. After 7 days of administration， the vaginal opening of female mice and the descent of testes and scrotum in male mice， as well as the ovarian and testicular organ indices， were observed. After 4 weeks of administration， female and male mice were housed together for 2 days， and the pregnancy rate of females was monitored. After delivery， the pregnant female mice continued receiving the treatment for 4 weeks， and the sexual development of their offspring， including vaginal opening， testicular descent， and organ indices of ovaries and testes， was observed. Serum sex hormones were measured by enzyme-linked immunosorbent assay （ELISA）， and the expression of gonadotropin-releasing hormone （GnRH） and growth hormone （GH） proteins in the hypothalamus was assessed by Western blot. ResultsCompared with the control group， there was no significant effect on the vaginal opening of female mice or the descent of testes in male mice after 7 days of SBC administration. After 4 weeks of administration， the pregnancy rate in the low-dose group was significantly reduced （P<0.05）， but no significant effects were observed in the other groups. The three doses of SBC did not significantly affect the ovarian or testicular organ indices， and there was no significant upregulation in the expression of GnRH or GH in the hypothalamus. The primary component of SBC， Pseudostellariae Radix polysaccharide， significantly reduced the vaginal opening in female mice after 7 days of administration （P<0.05）. After 4 weeks， the serum estradiol levels of non-pregnant female mice were decreased （P<0.05）， but there was no significant effect on the expression of GnRH or GH proteins in the hypothalamus of either male or female mice. Additionally， there were no significant effects on precocious puberty indicators， such as vaginal opening and testicular descent， in the offspring mice. ConclusionSBC does not significantly promote precocious puberty in young mice， and it does not have any noticeable effects on the pregnancy rate of adult mice or the sexual development of their offspring.

ObjectiveTo investigate the current status of latent tuberculosis infection (LTBI) among the elderly population in rural areas of Changxing County, Zhejiang Province, and to provide an evidence for the development of LTBI prevention and control measures. MethodsBetween January and May 2024, elderly individuals participating in urban and rural residents’ health checkups were screened for Mycobacterium tuberculosis infection using a domestically produced interferon-γ release assay (IGRA) kit. Individuals tested positive by IGRA but without active tuberculosis were classified as LTBI cases. The prevalence of LTBI among the participants was subsequently analyzed. ResultsAmong the 6 765 subjects, 637 tested positive by IGRA, including one identified active tuberculosis patient, resulting in a LTBI prevalence rate of 9.40%. There was a statistically significant difference in positivity rates across different IGRA methodologies (χ²=35.530, P<0.001). Higher LTBI rate was observed in males, individuals with a history of diabetes mellitus, and those with a history of pulmonary tuberculosis, exhibiting statistically significant differences (χ²=32.401, P<0.001; χ²=5.789, P=0.020; χ²=39.248, P<0.001, respectively.) No statistically significant difference in LTBI rate was found across different age groups (χ²=0.238, P=0.971). ConclusionThe prevalence of LTBI among the elderly rural residents in Changxing County is relatively low. Male, individuals with a history of diabetes mellitus, and those with a history of pulmonary tuberculosis have an increased risk of LTBI, warranting targeted risk monitoring and timely interventions.

The prevalence of Class III malocclusion varies among different countries and regions. The populations from Southeast Asian countries (Chinese and Malaysian) showed the highest prevalence rate of 15.8%, which can seriously affect oral function, facial appearance, and mental health. As anterior crossbite tends to worsen with growth, early orthodontic treatment can harness growth potential to normalize maxillofacial development or reduce skeletal malformation severity, thereby reducing the difficulty and shortening the treatment cycle of later-stage treatment. This is beneficial for the physical and mental growth of children. Therefore, early orthodontic treatment for Class III malocclusion is particularly important. Determining the optimal timing for early orthodontic treatment requires a comprehensive assessment of clinical manifestations, dental age, and skeletal age, and can lead to better results with less effort. Currently, standardized treatment guidelines for early orthodontic treatment of Class III malocclusion are lacking. This review provides a comprehensive summary of the etiology, clinical manifestations, classification, and early orthodontic techniques for Class III malocclusion, along with systematic discussions on selecting early treatment plans. The purpose of this expert consensus is to standardize clinical practices and improve the treatment outcomes of Class III malocclusion through early orthodontic treatment.

Phlegm-dampness syndrome is a common syndrome type of rheumatoid arthritis (RA), which is closely related to spleen dysfunction. Combined with the understanding of modern medicine on the pathogenesis of phlegm dampness and spleen dysfunction, it is believed that the important factors to promote the development of RA include inflammation related to lipid metabolism disorders, abnormal glucose regulation, and intestinal flora imbalance. Improper diet or external factors lead to glucose and lipid metabolism disorders and affect the imbalance of intestinal microbiota, causing damage to the intestinal mucosal barrier. The metabolites produced promote endogenous glucose and lipid metabolism imbalance and inflammatory response, thus forming the biological basis of RA with phlegm dampness syndrome. The method of invigorating spleen, removing dampness and resolving phlegm can correct the disorder of glucose and lipid metabolism in the body. It can also adjust endogenous glucose and lipid metabolism and inhibit RA inflammation by improving the composition of intestinal flora in RA patients, thus playing a therapeutic role.

The sternum is the pivotal component of the thoracic cavity. It is connected with the clavicle and ribs on the upper part and both sides respectively, and plays an important role in protecting the stability of the chest wall. Sternal resection usually results in a large segmental chest wall defect that causes the chest wall to float and requires sternal reconstruction. This paper reports a 62 years male patient with thymic squamous cell carcinoma with sternal metastasis, who underwent thymotomy, sternal tumor resection and autologous lilum graft combined with sternal reconstruction by titanium plate after relevant examination was completed and surgical contraindications were eliminated. The patient was followed up for 6 months, the respiratory and motor functions were normal and the thoracic appearance was good.

Aim To investigate the effects of 2-dode-cyl-6-methoxycyclohexa-2 , 5-diene-l, 4-dione ( DM-DD) on resisting hepatic fibrosis induced by carbon tetrachloride ( CC14 ) in rats and the underlying mechanisms , with a specific focus on the TGF-pi/Smads signaling pathway. Methods The hepatic fibrosis model was replicated using 50% CC14. Various parameters, including levels of aspartate transferase ( AST) , ala-nine transferase ( ALT ) , albumin/globulin ( A/G ) , total protein (TP) , total bilirubin (T-BIL) , hyaluron-ic acid ( HA ) , laminin ( LN ) , collagen type Ж ( Col Ж) , and collagen type IV(ColIV) in the blood, were measured. Liver tissue lesions and fiber formation were observed using HE and Masson staining. The expression levels of a smooth muscle actin (a-SMA) , collagen type I ( Col I ) , transformed growth factor (TGF-pi), Smad2, and Smad7 proteins were assessed using immunohistochemistry. a-SMA, Coll, TGF-pi, and Smad7 mRNA levels in liver tissue were measured by RT-PCR. Additionally, the expression levels of TGF-pi, Smad4, and Smad7 proteins in liver tissue were determined by Western blot. Results In comparison to the normal control group, the model group exhibited significantly elevated levels of AST, ALT, TP, T-BIL, HA, LN, Col Ш and Col IV in serum. But A/G level notably decreased. Successful modeling was confirmed by the presence of extensive fiber formations observed through HE and Massonstaining in liver tissue. The DMDD administration group demonstrated a notable decrease levels of AST, ALT, TP, T-BIL, HA, LN, Col III, and CollV, but A/G was significantly elevated when compared to the model group. Furthermore, a-SMA, Coll, TGF-f31, Smad2 and Smad4 mRNA and protein levels in the DMDD administration group were significantly reduced, while Smad7 significantly declined. HE and Masson staining results reflected a marked reduction in fibrous hyper-plasia. Conclusion DMDD exhibits a protective effect against CCl4-induced hepatic fibrosis, and its mechanism appears to be associated with the TGF-fJl/ Smads signaling pathway.

Exposure to occupational noise and heavy metals are common occupational hazards in workplaces. Occupational noise exposure not only leads to noise-induced hearing loss but also cognitive dysfunction. Exposure to common heavy metals such as lead, manganese, and cadmium during work is closely related to cognitive dysfunction in workers. Combined exposure to noise and heavy metals is common in workplaces. However, current research on the combined effects of exposure to occupational noise with lead or manganese on workers' cognitive function is not comprehensive or systematic. The method for cognitive dysfunction identification varies, leading to a lack of comparability. And the causality between occupational exposure and cognitive dysfunction in workers has not been clarified. Therefore, studying the cognitive dysfunction due to combined exposure to noise and common heavy metals is of great significance for workers' occupational health. In the future, it is necessary to unify the method for cognitive dysfunction identification and conduct systematic and comprehensive research on the effects, mechanisms, and combined effects of exposure to occupational noise with lead, manganese, cadmium, and other heavy metals on workers' cognitive dysfunction, to ensure the occupational health rights and interests of workers.

Hepatocellular carcinoma(HCC)has become the second leading cause of cancer-related death worldwide,ranking 6th among all tumors.Due to the lack of obvious early symptoms,most patients are diagnosed in the advanced stage,and the clinical benefits of surgical resection and hepatic artery chemoembolization and radiofrequency ablation are very limited.In recent years,the advent of immune-targeted therapies has revolutionized the systemic and systemic treatment of patients with advanced HCC,however,there is a lack of strong clinical evidence on the safety and efficacy of immune and targeted therapies for special populations,including patients with human immunodeficiency virus(HIV)infection,active autoimmune disease,decompensated cirrhosis(Child B or C),patients with diabetes-associated metabolic syndrome,patients with portal hypertension,vascular invasion,or portal vein thrombosis(PVT),and patients with liver transplantation(LT).This article reviews the current research progress of immune and targeted drugs in special populations.

Photon Counting Detector(PCD)is a device used to detect X-ray photons,which can directly convert the energy of photons into electrical signals to achieve photon counting and measurement.PCD-based energy spectrum computed tomography(PCD-CT)technology can provide additional energy spectral imaging information,and improve imaging quality while reducing radiation dose.Compared with energy integrating detectors(EID),PCD has advantages of high energy conversion efficiency,good imaging quality,exquisite structural design,and wide application range.It has broad application prospects in ultra-low-dose CT,specific disease diagnosis,and industrial inspection.The application of PCD-CT in spectral CT imaging was reviewed to provide a useful reference for its application in clinical medical diagnosis and industrial applications.
