Growth and development-related diseases result from the interplay of biological, psychological, and social factors. The collaboration between healthcare, sports, and education sectors integrates multidisciplinary resources and strengths to promote standardized diagnostic and therapeutic processes. This approach establishes a comprehensive closed-loop system encompassing early screening and referral, diagnosis and comprehensive evaluation, intervention and support plan formulation, as well as long-term management andoutcome assessment. It provides systematic scientific support for the healthy growth of children and adolescents, shifting disease intervention to the subclinical stage. Against the backdrop of societal informatization and intelligent development, this diagnostic and therapeutic model not only safeguards the holistic health of children and adolescents but also offers novel perspectives and feasible pathways for managing growth and development-related diseases. The implementation of this systematic diagnostic and therapeutic paradigm presents an innovative solution with Chinese characteristics for addressing such conditions, while injecting new vitality into the advancement of national health initiatives.

The growth and development of children is an important stage for health, and its monitoringand intervention are related to the long-term development of individuals. The construction of a standardized and multi-dimensional database of pediatric growth and development-related diseases is an important basis for realizing precise diagnosis and treatment and health management. Based on the needs of clinical practice, this study proposes to establish a specialized database of pediatric growth and development-related diseases that integrates facial phenotypes and clinical diagnosis and treatment information. This study elaborates on the construction process, including data sources, data collection content, and the operation and management of the database; and proposes key points for quality control, including the establishment of quality control nodes, database construction standards, and a full-process quality control framework. The above ensure the integrity, logic and effectiveness of the data, so that the database can provide an objective basis for the screening and diagnosis of pediatric growth and development-related diseases. On the basis of scientific data management and strict quality control, the database will help reveal the patterns of children's growth and development, and promote the level of children's health management.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Tropane alkaloids (TAs) are a class of anticholinergic drugs widely used in clinical practice and mainly extracted from plant, among which Atopa belladonna is the main commercial drug source. It is of great industrial value to obtain TAs in large quantities by plant metabolic engineering. In TAs pathway, cytochrome oxidase CYP82M3 catalyze the synthesis of tropinone and then tropinone reductase I (TRI) compete with TRII for tropinone to form tropine leading to the TAs synthesis (drainage). In this study, based on the "increasing flow and drainage" metabolic engineering strategy, two genes, namely HnCYP82M3 and DsTRI from Hyoscyamus niger and Datura stramonium, respectively, were overexpressed in the hair roots of A. belladonna, with a view to promote the TAs accumulation. The HnCYP82M3 gene was cloned from the root of H. niger, and it encoded amino acid with 91.7% sequence identity with AbCYP82M3 from A. belladonna. Overexpression of HnCYP82M3 alone did not affect the content of TAs in hair roots of A. belladonna, indicating that CYP82M3 was not a key enzyme in TAs biosynthesis. Simultaneous overexpression of HnCYP82M3 and DsTRI greatly promoted the accumulation of the three TAs, and the contents of hyoscyamine, anisodamine and scopolamine were 4.97 times, 2.83 times and 2.19 times that of the control, respectively, and the increase amplitude was greater than that of single overexpression of DsTRI. This study showed that the "increasing flow and drainage" strategy of enzyme genes co-expression at branch points was a promising metabolic engineering method to effectively improve the biosynthesis of TAs in A. belladonna, and laid a theoretical and technical foundation for the large-scale industrial acquisition of TAs.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To observe any effect of bilateral high-frequency repetitive transcranial magnetic stimulation (rTMS) of the cerebellum on the swallowing of stroke survivors with dysphagia.Methods:Thirty-eight patients with post-stroke dysphagia were randomly divided into a cerebellar stimulation group of 20 and a sham group of 18. In addition to drug therapy and physical rehabilitation training, the cerebellar stimulation group received 500 pulses of rTMS of the cerebellum daily at 10Hz and 120% of the resting movement threshold lasting 1s at 9s intervals. The sham stimulation group was treated with sham rTMS (with the angle between the stimulation coil and the scalp at 90°). Twenty minutes later, both groups were given 30 minutes of routine swallowing training daily by the same speech therapist. The treatment was administered 5 times a week for 3 weeks. Before the treatment and afterward, both groups′ swallowing was evaluated y videofluoroscopic swallowing study (VFSS), using a functional dysphagia scale (FDS) and using the Rosenbek penetration aspiration scale (PAS). Oral transport time, swallowing response time, pharyngeal transport time, laryngeal vestibular closure time and upper esophageal sphincter opening duration were recorded, and the changes in swallowing function and swallowing time parameters before and after the treatment were compared between the two groups.Results:Before the stimulation there were no significant differences between the two groups. Afterward, the average PAS and FDS scores of both groups had improved significantly, but with significantly greater improvement in the cerebellar stimulation group than in the sham group. Average oral transit time and swallow response time had shortened significantly, but with significantly shorter time, on average, in the cerebellar stimulation group.Conclusion:Bilateral high-frequency rTMS of the cerebellum can improve the swallowing of persons with dysphagia, and shorten their oral transit time and swallow response time.

【Objective】 To investigate the role of RRM2 in prostate cancer and the mechanism. 【Methods】 The data of prostate cancer expression profile were downloaded from The Cancer Genome Atlas (TCGA). The correlation between RRM2 expression and clinicopathological features and prognosis of prostate cancer was analyzed. The protein expressions of RRM2 in 55 cases of prostate cancer and 38 benign tissues were determined with immunohistochemistry (IHC). The effects of RRM2 on the biological process of prostate cancer were assessed with bioinformatic analysis. The biological process of RRM2 affecting the progression of prostate cancer was verified with Western blot and flow cytometry. 【Results】 RRM2 was highly expressed in prostate cancer, and the expression was positively correlated with the clinical stage, pathological grade and metastasis of prostate cancer (P<0.05). Higher RRM2 expression predicted poorer survival. RRM2 co-expression positively correlated genes were involved in cell cycle pathways, pyrimidine nucleotide metabolism, and biological processes such as RNA transport. Cell cycle pathways were significantly enriched. RRM2 was highly correlated with CDK1 and PCNA molecules. RRM2 knockdown reduced the protein expressions of CDK1 and PCNA in DU145 and LNCap cell lines, which were arrested in the G2/M phase. 【Conclusion】 RRM2 promotes tumor progression by interfering with G2/M cycle of prostate cancer cells.

Objective:To observe any stimulatory effect of intermittent theta burst stimulation (iTBS) on the cerebral swallowing cortex and the cerebellar swallowing motor area and to explore the related mechanisms.Methods:Forty-four healthy right-handed subjects were divided at random into a dominant cerebellum group ( n=15), a non-dominant cerebellum group ( n=15) and a control group ( n=14). In the dominant cerebellum group, iTBS was administered to the cerebellum of the dominant hemisphere, and the other hemisphere was given sham stimulation. In the non-dominant cerebellum group, it was the opposite. The dominant cerebellum received the sham stimulation. In the control group both hemispheres received sham stimulation. Before and after the stimulation, single-pulse transcranial magnetic stimulation (TMS) was applied to the representative regions of suprahyoid muscles in bilateral brain and cerebellum to observe changes of the latency and amplitude of motor evoked potentials (MEPs). Results:After the intervention the MEP amplitude of the bilateral swallowing cortex and the stimulated cerebellum had increased in the non-dominant cerebellum group, with increased MEP amplitude only from the stimulated cerebellum of the dominant cerebellum group. Compared with the control group, the non-dominant cerebellum group showed the greatest improvement in MEP amplitude of the stimulated bilateral cerebral cortex and cerebellum. Improvement in the dominant cerebellum group was significantly smaller. However, there were no significant differences in MEP latency or the percentage change in MEP latency from baseline among the three groups.Conclusions:Applying iTBS to either the non-dominant or the dominant cerebellum excites the brain areas related to swallowing, but in different ways.

OBJECTIVE To evaluate the effect and mechanism of Qili Huanshao Formula(QLHSF)in ameliorating sex hormone disturbance and oxidative damage in testicular tissues of D-galactose-induced subacute aging mice.METHODS 105 male mice were randomly divided into the normal group,model group,low,medium and high doses of QLHSF group,vitamin E(VE)group and Jin Gui Shen Qi Wan(JGSQW)group.The subacute senescence model was established by continuous intraperitoneal injection of D-galac-tose(D-gal)and treated by intragastric administration,as well.The testicular histopathological damage was detected by HE staining.The levels of relevant sex hormones in serum were detected by ELISA.The expression of oxidative stress factors was detected by related kits.The apoptotic cells in testicular tissue were detected by TUNEL assay,and the expressions of oxidative stress and apop-totic related proteins in the testicular tissues of mice were detected by Western blot.RESULTS Compared to the aging model mice,all dose groups of QLHSF could obviously improve testicular tissue pathological damage.The levels of T,E2 and GnRH levels were in-creased,while LH and FSH were decreased in serum(P<0.01).Meanwhile,the SOD activity(P<0.01)and the levels of GSH(P<0.01)were increased,while MDA levels(P<0.01)were decreased in serum and testicular tissues.The medium dose group of QLHSF significantly inhibited testicular cell apoptosis(P<0.01),increased the expression of Nrf2,HO-1 protein and Bcl-2/Bax ratio(P<0.05),and down-regulated the expressions of Cleaved-Caspase-3/Caspase-3,Cleaved-Caspase-9/Caspase-9 apoptotic protein in the testis of mice(P<0.05).CONCLUSION QLHSF can effectively improve sex hormone disturbance and protect testicular tissue in aging mice,and the mechanism of action might be related to the inhibition of oxidative stress-induced apoptosis in testicular tissues.The study will provide reference and lay the foundation for the clinical application and functional anti-aging product develop-ment of Lycium barbarum and its formulations.
