Objective: To observe the effect oftuina plus music therapy on range of motion of ankle joints and muscle spasm of lower limbs in children with spastic cerebral palsy. Method:All of 286 cases that conformed to the diagnostic criteria of infantile cerebral palsy were treated with 7 types of tuina manipulations respectively to unblock the Governor Vessel, reinforce the kidney and strengthen the spleen, pinch along the spine, stimulate specific foot-reflex area and different spinal segments, accelerate recovery of muscle strength and increase joint range of motion, 25-30 rain each treatment, once or twice a day, 30 d constitute a course of treatment.After this, the efficacy on femoral medial adduction and dorsiflexion angle and composite spasticity score (CSS) was evaluated. Result: The statistical analysis showed significant differences in dorsiflexion and femoral medial adduction angle and CCS scores (P<0.01) after the treatments. Conclusion: Tuina plus music therapy can lubricate the joints, relax contraction of tendons, alleviate muscle spasm and improve scissors and toe-walking gaits, thereby benefiting the gross motor function of infants in sitting, kneeling, standing and walking.

Objective:To investigate the signaling pathway of inhibiting macrophage phagocytosis of TIR domain-containing protein encoded by Escherichia coli (TcpC) N-terminal ubiquitin ligase active fragments of uropathogenic Escherichia coli. Methods:Bioinformatics software was used to analyze the amino acid sequences and the function of TcpC N-terminal ubiquitin ligase active fragments as well as the functional sites. PCR was performed to amplify tcpc-330, tcpc-450 and tcpc-510 genes and a prokaryotic expression system was constructed to express the target proteins. The recombinant proteins rTcpC-N110, rTcpC-N150 and rTcpC-N170 were purified by Ni-NTA affinity chromatography. LPS in the recombinant proteins was removed by Detoxi-gel chromatography. The expression of MyD88 at protein and mRNA levels in macrophages incubated with rTcpC-N110, rTcpC-N150, rTcpC-N170 or rTcpC-TIR was detected by Western blot and qRT-PCR. The activation of NF-κB signal pathway and the levels of proinflammatory factors in macrophages incubated with the above TcpC protein fragments were measured by Western blot and ELISA, respectively. Results:Cys12, Trp104 and Trp106 in the N-terminal fragment of TcpC were crucial amino acids in maintaining its ubiquitin ligase activity. The target recombinant proteins rTcpC-N110, rTcpC-N150 and rTcpC-N170 were successfully expressed and purified. After Detoxi-gel chromatography, rTcpC-N110, rTcpC-N150 and rTcpC-N170 extracts were undetectable for LPS. TcpC ubiquitin ligase fragments inhibited the expression of MyD88 at protein level, but not affect its expression at mRNA level in macrophages. LPS-induced phosphorylation of NF-κB signaling pathway-related proteins p50 and p65 was significantly inhibited in macrophages treated with TcpC ubiquitin ligase fragments. Moreover, LPS-induced production of pro-inflammatory factors was also significantly inhibited.Conclusions:The recombinant proteins rTcpC-N110, rTcpC-N150 and rTcpC-N170 could inhibit the expression of MyD88 at protein level and suppress the activation of NF-κB signaling pathway, suggesting that they were closely related to the inhibition of innate immune activity of macrophages.

This study adopted the policy text analysis method,review the historical background of the enactment,aimed to comparatively analyze the international pharmaceutical trade policies of the BRICS countries.The main objectives of the BRICS countries'international pharmaceutical trade policies included ensuring stable and accessible drug supply,expanding exports of domestic products and creating a favorable political environment.For these purposes,Brazil,Russia,and South Africa all ensure drug supply through substantial imports.However,they have also taken measures such as compulsory patent licensing and promoting localization of production by foreign companies to reduce import dependence.India,on the other hand,protects its domestic industry by resisting drug imports to ensure drug supply while simultaneously promoting the export of pharmaceutical products.China continually optimizes approval and data monitoring procedures to align with international standards,creating a favorable trade environment and expanding exports.China should further refine its international pharmaceutical trade policies while ensuring the autonomy of domestic drug research and supply,fostering stronger collaboration within BRICS nations and promoting global access to public healthcare products.

BACKGROUNDH syndrome (OMIM 612391) is a recently described autosomal recessive genodermatosis characterized by indurated hyperpigmented and hypertrichotic skin, as well as other systemic manifestations. Most of the cases occurred in the Middle East areas or nearby countries such as Spain or India. The syndrome is caused by mutations in solute carrier family 29, member 3 (SLC29A3), the gene encoding equilibrative nucleoside transporter 3. The aim of this study was to identify pathogenic SLC29A3 mutations in a Chinese patient clinically diagnosed with H syndrome.

METHODSPeripheral blood samples were collected from the patient and his parents. Genomic DNA was isolated by the standard method. All six SLC29A3 exons and their flanking intronic sequences were polymerase chain reaction (PCR)-amplified and the PCR products were subjected to direct sequencing.

RESULTSThe patient, an 18-year-old man born to a nonconsanguineous Chinese couple, had more extensive cutaneous lesions, involving both buttocks and knee. In his genomic DNA, we identified a novel homozygous insertion-deletion, c. 1269_1270delinsA, in SLC29A3. Both of his parents were carriers of the mutation.

CONCLUSIONSWe have identified a pathogenic mutation in a Chinese patient with H syndrome.

Objective: To explore the relationship between childhood abuse, adult attachment and borderline personality disorder (BPD) in college students, and to provide reference for promoting the physical and mental health of college students. Methods: We selected undergraduate students from four colleges in Hefei, a total of 4 034 college students were surveyed by the childhood trauma questionnaire short form(CTQ-SF), the state adult attachment measure (SAAM) and the Personality Diagnostic Questionnaire(PDQ). Results: BPD was found in 4.2% of subjects, 4.5% of males and 3.7% of females. The score of BPD in non-single-parent families was lower than that in single-parent families, in families with average family economic status was lower than that in families with poor and good family economic status, and in families with medium father education level was lower than that in fathers with low and high education level(Z=-2.30, 29.25, 9.63, P<0.05). Childhood abuse, avoidant attachment and anxious attachment positively predicted BPD(β=0.21, 0.10, 0.23, P<0.01), secure attachment negatively predicted BPD(β=-0.15, P<0.01). Adult attachment played a partial mediating role in the effects of childhood abuse on BPD, with the mediating effect accounting for 16.7% of the total effect. Conclusion Adult attachment plays a mediating role in the effects of childhood abuse on BPD.

OBJECTIVE: To explore the genetic basis for a child with mental retardation. METHODS: Whole exome sequencing was carried out for the child. Candidate variant was screened based on his clinical features and verified by Sanger sequencing. RESULTS: The child was found to harbor a c.995_1002delAGACAAAA(p.Asp332AlafsTer84) frameshift variant in the SYNGAP1 gene. Bioinformatic analysis suggested it to be pathogenic. The same variant was not detected in either parent. CONCLUSION The c.995_1002delAGACAAAA(p.Asp332AlafsTer84) frameshift variant of the SYNGAP1 gene probably underlay the mental retardation in this child. Above finding has expanded the spectrum of SYNGAP1 gene variants and provided a basis for the diagnosis and treatment for this child.
