[Objective] To investigate the antigen and gene frequency distribution of the MNS blood group system in the Han population of voluntary blood donors in Suzhou, and to explore the polymorphism of rare MNS blood group genes, in order to improve the construction of the local rare blood group database. [Methods] A total of 8 034 whole blood samples were randomly collected from Han blood donors at our station from October 2023 to June 2024. The MNS blood group phenotypes were identified using serological methods. Gene frequencies were analyzed and compared with those of ethnic populations in other regions. Rare MNS phenotype samples were subjected to gene sequencing. [Results] The distribution of MNS blood group system phenotypes within the population was as follows: the MM, NN, and MN phenotypes accounted for 23.00%, 27.12%, and 49.88% respectively; the SS, ss, and Ss phenotypes accounted for 0.30%, 90.99%, and 8.70% respectively. The gene frequencies of M, N, S, and s were 0.4794, 0.5206, 0.0465, and 0.9534 respectively. Chi-squared tests confirmed adherence to Hardy-Weinberg equilibrium with P-values of 0.997 and 0.349, showing statistical significance compared to some other regional ethnic populations (P<0.05). Additionally, one rare serological phenotype, S-s-, with a frequency of 0.01%, was identified. [Conclusion] The MNS blood group system in the Han population of voluntary blood donors in Suzhou exhibits polymorphism and regional distribution characteristics. Gene frequencies differ from those observed in other regions of China. It is essential to enhance the establishment of a rare blood type database in Suzhou to provide data support for precise clinical transfusion.

Objective:To explore the interaction needs between depressed adolescents with non-suicidal self-injury behavior and their parents.Methods:From June to November 2023, purposive sampling was used to select depression adolescents with non-suicidal self-injury behavior and their parents admitted to Huai'an Third People's Hospital as respondents. The semi-structured interview was used to collect data. The paired interview and Colaizzi 7-step analysis methods were used to analyze and summarize interview data.Results:Fifteen pairs of adolescents and their parents were interviewed. The needs of depressed adolescents with non-suicidal self-injury behavior for parental attention were summarized as controlling emotions, empathetic perception, reducing stress, mental dependence, autonomous decision-making, and mutual respect. The needs of parents for depressed adolescents with non-suicidal self-injury behavior were summarized as overcoming depression, restoring education, emotional response, actively seeking help, deep communication, and easing relationships.Conclusions:There are various interactive needs between depressed adolescents with non-suicidal self-injury behavior and their parents, which are closely related but contradictory in coping with the illness. It is recommended that medical and nursing staff conduct research on patients and their parents as a whole and provide personalized and targeted two-way guidance and emotional support through in-depth understanding and careful consideration of the multi-level interaction needs of both parties.

OBJECTIVE:
To study the impacts of varicocele (VC) and varicocelectomy (VCT) on the proteomics of rat testis tissue, and to analyze the differential proteins and signaling pathways, and observe the microstructural changes of the testis tissue.
METHODS:
We selected 60 male SD rats and divided them into a sham operation (SO), a VC model control, and a VCT group. We harvested the testis tissues from the rats at 4 weeks after modeling for determination of the differential protein expressions by mass spectrometry, analysis of the changes in the protein signaling pathways by KEGG pathway repolarization, and observation of the microstructural changes in the spermatogenic cells under the transmission electron microscope (TEM).
RESULTS:
A total of 15 clinically significant proteins were effectively identified, among which RPS24, KIFAP3, HPX, RPL38, TOP2A, PRPF19, TRPM3, RPL32, CNBP and AHSG were upregulated, while RPS9, TKFC, SH3BGRL3, ACAA2 and FABP3 downregulated. The differential pathways found included the Type-I 4-aminobutyrate degradation pathway, eIF2 signaling pathway, and Type-III glutamate degradation pathway, which were all related to the pathogenesis of testicular growth arrest. Compared with the rats in the VCT group, those of the VC group rats showed ultrastructural changes in the testis tissue under the TEM, such as mitochondrial vacuolar degeneration, dense nucleoli, invagination of cell nuclear membranes, and irregularity, which were detrimental to the survival of testicular cells.
CONCLUSION
VCT affects the development and growth of the testis by altering the expressions of relevant proteins and influencing the changes of the gene pathways in the testicular cells, which may be one of the causes of VC inducing testis injury and testicular spermatogenic dysfunction. The changes in these molecular pathways can provide some theoretical evidence for an insight VC as well as potential therapeutic targets for its treatment.

The discussion and research on the clinical dominant diseases of traditional Chinese medicine (TCM) have attracted increasing attention. Through approaches including modern technology, evidence-based medical methods, and multi-disciplinary treatment, we should construct a sound TCM inheritance and innovation system, establish a collaborative innovation mechanism, and integrate major research projects, striving to make breakthroughs in TCM theory, methodology, standards, and regulation system, promoting the scientific and technological progress of TCM, and thereby improving its curative effect. The China Association of Chinese Medicine (CACM) carried out a series of youth salon seminars for clinical dominant diseases in TCM, discussing and sorting out the advantages of the dominant diseases in clinical diagnosis and treatment of TCM and integrated traditional Chinese and western medicine in specific diseases or fields. Authoritative experts in the industry were invited to give comment and guidance to form a report. Centering on clinical research of dominant diseases, thematic research was carried out in the aspects of practice, human experience-based evidence, and transformation path. Through the systematic study of the dominant diseases, the advantages of TCM in different stages of disease treatment were excavated to constantly improve the prevention and treatment ability of TCM and carry forward the advancement of TCM theory and practice. At the same time, the communication and understanding between traditional Chinese and western medicine were improved, laying the foundation for the further formation of industry guidelines or consensus and comprehensive promotion. These seminars are expected to provide references for the development of policy planning, clinical diagnosis and treatment, health economy, and social services in TCM and lay the foundation for the formation of a new modern diagnosis and treatment system with Chinese characteristics.

Objective:To explore the clinical efficacy of Masquelet technique combined with tissue flap transfer in the treatment of infectious composite bone and soft tissue defects in the early and middle stages after internal fixation for tibial fractures.Methods:From October 2017 to November 2020, 12 patients (13 tibial fractures) with infectious bone and soft tissue defects in the early and middle stages after internal fixation were treated in the Department of Orthopaedics, 988th Hospital of the Joint Logistics Support Force of CPLA by two-phased surgery with retaining internal fixation. Phase I procedures were thoroughly removal of the infected lesions and failed screws, preserving internal implants as many as possible, implantation of absorbable calcium sulphate and an antibiotics blended string of beads into the distal and proximal medullary cavity of the fractured bones, filling the bone defect and wrapping the internal implants with antibiotics loaded bone cement. The size of defects was 3.5 cm × 5.0 cm-7.5 cm × 14.5 cm, and the flaps for wound coverage sized 4.0 cm × 5.5 cm-8.0 cm × 15.0 cm. As for the repair of donor site, 8 limbs were sutured directly, 5 limbs could not be closed completely, and the remaining wounds were covered by skin grafting after suture. Based on well control of infection and stable clinical signs, fillings of bone cement were then removed in Phase II surgery, or 6-9 weeks after primary surgery. Autologous cancellous bone pieces or composite allogeneic bone were fully implanted around the induction membrane formed by Masquelet technique, and auxiliary steel plates were implanted for internal fixation of unstable fractures. After discharge, the patients visited the outpatient clinic regularly, and combined with Wechat follow-up. The texture, colour and bone healing were observed. At the last follow-up, the function of the affected limbs were assessed according to Johner-Wruhs evaluation standard.Results:After Phase I surgery, 13 flaps survived smoothly without vascular compromise. The wounds healed in Phase I. Two patients (2 sides) had recurrent infections. Re-debridement was performed and external fixation was applied after removal of internal fixation. After Phase II surgery, all patients were included in 12-26 months of follow-up, with an average of 18 months. Thirteen lower leg fractures healed well, and the time of bone healing was 16-25 (average 19.5) weeks. The Johner Wruhs criteria was used in evaluation of the function of affected limbs, and it was found that 6 patients were in excellent, 5 in good and 2 in fair.Conclusion:It is feasible while preserving the internal implants, to use membrane induction technique (Masquelet technique) combined with flap transfer, together with the absorbable calcium sulphate antibiotic sustained-release beads as a carrier in the phased treatment of infectious bone defects and bone exposure in the early and middle stages after the surgery of tibial internal fixation. It also gives a higher rate of excellence in surgical outcome. This study explores a treatment procedure for traumatic bone infection combined with composite soft tissue defects.

Objective To analyze the polymorphism of Plasmodium lactate dehydrogenase (pLDH) gene and predict B-cell epitopes in pLDH peptides in four species of human malaria parasites. Methods The blood samples and epidemiological characteristics were collected from malaria cases in Yunnan Province registered in the National Notifiable Disease Report System. The pLDH genes of four human Plasmodium species were amplified using nested PCR assay and sequenced. The polymorphisms of pLDH genes was analyzed using the software MEGA version 7.0.26 and DnaSP version 5.10, and the B-cell epitopes were predicted in pLDH peptides using the Immune Epitope Database (IEDB). Results The sequences of P. vivax LDH (PvLDH), P. falciparum LDH (PfLDH), P. ovale LDH (PoLDH) and P. malariae LDH (PmLDH) genes were obtained from 153, 29, 17 and 11 blood samples from patients with P. vivax, P. falciparum, P. ovale and P. malariae malaria, respectively, which included 15, 2, 4 and 2 haplotypes and had a nucleotide diversity (π) of 0.104. A high level of intra-species differentiation was seen in the PoLDH gene (π = 0.012), and the π values were all < 0.001 for PvLDH, PfLDH and PmLDH genes. Active regions of B-cell antigen were predicted in the pLDH peptide chain of four human malaria parasites, of 4 to 5 in each chain, and the activity score was approximately 0.430. Among these peptide chains, the “86-PGKSDKEWNRD-96” short-peptide was a B-cell epitope shared by all four species of human malaria parasites, and the “266-GQYGHS (T)-271” short-peptide was present in PvLDH and PoLDH peptide chains, while “212-EEVEGIFDR-220” was only found in the PvLDH peptide chain, and “208-LISDAE-213” was only seen in the PfLDH peptide chain. Conclusions The PoLDH gene polymorphism may be derived from the weak negative purification selection, while PvLDH, PfLDH and PmLDH genes may maintain a relatively conservative state. There may be two B-cell epitopes “212-EEVEGIFDR-220” and “208-LISDAE-213” in the proximal region of the C terminal in the pLDH peptide chain, which is feasible to differentiate between P. vivax and P. falciparum infections.

Background: Esophageal cancer is one of the leading causes of cancer deaths worldwide. T-cell immunoglobulin and mucin domain-containing protein 3 (Tim-3) has been shown to be implicated in the tumor immune escape, and associated with tumor progression and poor prognosis in a variety of malignancies. Aims: To investigate the expression of Tim-3 in esophageal tumorigenesis and its clinical significance. Methods: Paraffin-embedded tissues from 103 esophageal cancer, 21 high-grade esophageal intraepithelial neoplasia, 16 low-grade esophageal intraepithelial neoplasia, and 20 chronic esophagitis were collected in this study. Using immunohistochemistry, the expression level of Tim-3 was evaluated; and the correlation of Tim-3 expression in cancerous tissue with the clinicopathological parameters of esophageal cancer was analyzed. Results: Tim-3 expression was increased from chronic esophagitis, low-grade intraepithelial neoplasia, high-grade intraepithelial neoplasia to esophageal cancer (0.271±0.138, 0.368±0.198, 0.443±0.147, and 0.639±0.119, P<0.05). Moreover, Tim-3 expression was significantly correlated with depth of tumor invasion, regional lymph node metastasis and TNM staging of esophageal cancer (P<0.05), whereas no relationship was found between Tim-3 expression and gender, age and tumor location of esophageal cancer (P>0.05). Conclusions: Tim-3 expression is increased in esophageal tumorigenesis; overexpression of Tim-3 in esophageal cancer is closely correlated with tumor progression. Tim-3 might be served as a biomarker for development, progression and prognosis of esophageal cancer.

Objective To understand the epidemic situation and the source of infection of the reemerge human rabies in Qinghai. Methods We collected the data on human rabies and the data on the cases of multi- victims bitten by the identical dog, and also the laboratory data of the nucleoprotein ( N) gene of rabies virus from the samples which were detected by reverse transcription-polymerase chain reaction (RT-PCR) and direct immunofluorescence assay (DFA) from 2012 to 2017, to describe the epidemiological characteristics of human rabies and the prevalence of rabies virus in host animals, and to explore the source of infection of reemerge human rabies. Results A total of 7 human cases were reported in 2012-2017 in Qinghai province, among which 1 was bitted by wolf, 2 were bitted by stray dogs, 3 were bitted by domestic dogs which injured by stray dogs or wolfs. A total of 892 canine brain tissue samples were collected, from which 46 positive samples were detected with the positive rate of 5.16% (95% CI:3.70%-6.61%). The positive samples were collected from the nomadic region, which were consistent had the location of the human rabies. The samples collected from the cases of multi-victims bitten by the identical dog/animal had the positive rate of 73.08%, and 4 out of 7 human rabies were exposed to the cases of multi-victims bitten by the identical dog/animal. Genetic sequencing of the rabies virus detected from canine brain tissue samples were belong to China IV lineage, which was closely related to the Arctic clade. Conclusions The reemerging rabies happened in nomadic region of Qinghai province could be a consequence of spillover from wildlife especially from wolfs. The better surveillance system covering the human, livestock and wildlife should be set up to mitigate the rabies virus spread from the wildlife.
