Aim To systematically investigate the ac-tive components,targets,and regulatory pathways of Po-lygonum capitatum in intervening atherosclerosis(AS)through network pharmacology,molecular docking and animal experiments.Methods Active components of Polygonum capitatum and AS-related targets were screened and identified through database searches.Protein-protein interaction(PPI)network analysis was performed using the STRING database,followed by GO and KEGG enrichment analyses via the David plat-form.Molecular docking validation was conducted with AutoDock.An AS model was established in Syrian golden hamsters fed a high-fat diet.Predicted pathways and targets were validated using qPCR,ELISA,and histopathological assessment of aortic and hepatic tis-sues via HE staining.Results Network pharmacology identified 27 potential active components of Polygonum capitatum(primarily flavonoids such as quercetin and luteolin)and 110 drug-disease intersection targets,in-cluding core targets MMP-9,ALB,and AKT1.GO and KEGG analyses enriched 593 and 125 pathways,re-spectively,with the NF-κB inflammatory pathway,TNF signaling pathway and lipid metabolism/atherosclerosis pathways highlighted as key mechanisms.Animal ex-periments demonstrated that Polygonum capitatum im-proved serum lipid profiles(reduced TC,TG,LDL-C)in AS hamsters,suppressed the MMP-9/NF-κB signa-ling pathway(downregulated MMP-9,p65 phosphoryla-tion,TNF-α,and IL-6),and inhibited VSMC synthetic phenotypic transformation(upregulated α-SMA and myocardin)by downregulating MCPIP1.Additionally,Polygonum capitatum ameliorated aortic lesions and he-patic lipid deposition in AS hamsters.Conclusions Polygonum capitatum alleviates AS by synergistically regulating the MMP-9/NF-κB/MCPIP1 axis through flavonoid components,suppressing vascular inflammato-ry cascades and maintaining VSMC contractile pheno-types.This reflects Polygonum capitatum's multi-com-ponent,multi-pathway,and multi-target characteristics in combating AS.

Objective: To evaluate the protective effect of jailed balloon technique on side branch (SB) ostium using three-dimensional optical coherence tomography(OCT). Methods: This is a retrospective study. Consecutive coronary disease patients with coronary artery bifurcation lesions who underwent percutaneous coronary intervention (PCI) and completed pre-and post-procedural OCT examinations at the Chinese People's Liberation Army General Hospital from September 2019 to March 2022 were enrolled. Patients were divided into the jailed balloon technique group and the unprotected group according to the options applied for the SB. The SB ostium area difference was calculated from OCT images (SB ostium area difference=post-PCI SB ostium area-pre-PCI SB ostium area). The SB ostium area differences were compared between the two groups and compared further in the subgroup of true bifurcation lesions and non-true bifurcation lesions. In the jailed balloon group, the SB ostium area difference was compared between the active jailed balloon technique and the conventional jailed balloon technique, between the jailed balloon>2.0 mm diameter and the jailed balloon≤2.0 mm diameter, and between the higher balloon pressure (>4 atm, 1 atm=101.325 kPa) and the lower balloon pressure (≤4 atm). Multivariate linear regression analysis was used to explore the correlation between the technical parameters of the jailed balloon technique and the SB protection effect. Results: A total of 176 patients with 236 bifurcation lesions were enrolled, aged (60.7±9.3) years, and there were 128 male patients (72.7%). There were 67 patients in the jailed balloon technique group with 71 bifurcation lesions and 123 patients in the unprotected group with 165 bifurcation lesions. Fourteen patients had 2 to 3 lesions, which were treated in different ways, so they appeared in the unprotected group and the jailed balloon technique group at the same time. The area difference in SB ostium was greater in the jailed balloon group than in the unprotected group (0.07 (-0.43, 1.05)mm² vs.-0.33 (-0.83, 0.26)mm², P<0.001), and the results were consistent in the true bifurcation lesion subgroup (0.29 (-0.35, 0.96)mm² vs.-0.26 (-0.64, 0.29)mm², P=0.004), while the difference between the two groups in the non-true bifurcation lesion subgroup was not statistically significant (P=0.136). In the jailed balloon technique group, the SB ostium area difference was greater in patients treated with the active jailed balloon technique than in those treated with the conventional jailed balloon technique ((0.43±1.36)mm² vs. (-0.22±0.52)mm², P=0.013). The difference in SB ostium area was greater in those using>2.0 mm diameter jailed balloons than in those using≤2.0 mm diameter jailed balloons (0.25 (-0.51, 1.31) mm² vs.-0.01 (-0.45, 0.63) mm², P=0.020), while SB ostium area difference was similar between those endowed with higher balloon pressure (>4 atm) compared to those with lower balloon pressure (≤4 atm) (P=0.731). Multivariate linear regression analysis showed that there was a positive correlation between jailed balloon diameter and SB ostium area difference (r=0.344, P=0.019). Conclusions: The jailed balloon technique significantly protects SB ostium, especially in patients with true bifurcation lesions. The active jailed balloon technique and larger diameter balloons may provide more protection to the SB.

Aim To observe the effect of CP-25 on the ESS mouse model and establish whether its effect is through regulating the binding of GRK2 to JAK1 and inhibiting the JAK1-STAT1/2-CXCL13 signaling pathway. Method We established ESS mouse model induced by SG protein, established into normal group, model group, CP-25 group with concentration of 35 mg • kg"1, 70 mg • kg"1, and HCQ group with concentration of 80 mg • kg"1. Mouse saliva flow was measured. The infiltration of lymphocyte in SG was observed by HE staining. The expression of p-JAKl, p- STAT1 and p-STAT2 in submandibular gland tissue was detected by Western blot. The level of CXCL13 in SG of mice was tested by IHC. GRK2 and JAK1 binding was determined by immunofluorescence and CO- IP. Results Compared with normal group, the saliva flow rate of ESS mice was low and lymphocytes were significantly infiltrated in the submandibular gland pathological sections. The CXCL13 protein level was highly expressed, which activated the JAK1-STAT1/2 signal. CP-25 significantly increased the salivary flow rate in ESS mice, reduced lymphocyte infiltration, improved pathological abnormalities, and inhibited the expression of JAK1-STAT 1/2 signaling and CXCL13. CP-25 significantly promoted the binding of GRK2 to JAK1. Conclusions CP-25 may inhibit the binding of GRK2 to JAK1, and then inhibit the activation of JAK1-STAT1/2-CXCL13 signaling pathway, improve the abnormal pathological manifestations of lymphocyte infiltration in submandibular gland, and improve the rate of saliva flow. CP-25 plays a therapeutic role in ESS mice.

OBJECTIVE: To investigate the nutritional status of children with cerebral palsy (CP) and the clinical effectiveness of Subjective Global Nutritional Assessment (SGNA) in nutritional assessment of hospitalized children with CP. METHODS: A total of 208 children with CP, aged 1-5 years, who were hospitalized from April to October 2019 were enrolled as subjects. SGNA was used to investigate nutritional status, and the Z-score method recommended by the World Health Organization was used as a reference standard to validate the clinical effectiveness of SGNA. RESULTS: The detection rate of malnutrition in children with CP was 42.3% by SGNA and 39.4% by the Z-score method (P>0.05). The application of SGNA showed high consistency between different evaluators (κ=0.621, P<0.001). With the Z-score method as the reference standard, SGNA had a sensitivity of 80.5%, a specificity of 82.5%, a positive predictive value of 75.0%, and a negative predictive value of 86.7%, and high consistency was observed between the two evaluation methods (κ=0.622, P<0.001). SGNA was moderately consistent with weight-for-age Z-score and height-for-age Z-score (κ=0.495 and 0.478 respectively, P<0.001) and was poorly consistent with weight-for-height Z-score (κ=0.197, P<0.05). CONCLUSIONS There is a relatively high incidence rate of malnutrition in children with CP. SGNA can be used as a tool to assess the nutritional status of children with CP.

OBJECTIVE: To observe the correlation between referred pain distribution and acupoint sensitization in patients with intestinal diseases. METHODS: In clinical research, 443 patients from 8 hospitals were recruited, including the outpatients and inpatients of Crohn's disease (=143), ulcerative colitis (=108), chronic appendicitis (=87) and other intestinal diseases (=105). The site with tenderness on the body surface and the morphological changes of local skin were observed and recorded in the patients. Using a sensory tenderness instrument, the pain threshold at the sensitization point was measured in 60 patients with ulcerative colitis. In animal experiment, SD rats were used and divided into a enteritis group (=8), in which the enteritis model were established, and a control group (=3), in which no any intervention was given. After the injection of Evans blue (EB) at caudal vein, the blue exudation points on the body surface were observed and the distribution rule was analyzed statistically. RESULTS: The referred pain on the body surface in the patients with intestinal diseases was mainly located in the lower abdomen (93.9%, 416/443), the lumbar region (70.9%, 314/443) and the lower legs (33.0%, 146/443). The diameter of tenderness region was 1.5 to 2.5 cm. Compared with the region without sensitization, the pain threshold of the sensitization point in the patients with ulcerative colitis was reduced significantly (<0.001). The referred pain on the body surface in the patients with appendicitis was located in the right lower abdomen (97.7%, 85/87), the waist and back (54.0%, 47/87) and the right lower limbs on the medial side (71.3%, 62/87). The tenderness region was 1 to 2 cm in diameter and was irregular in form. After modeling of enteritis in the rats, the EB exudation points were visible from T to L. CONCLUSION Intestinal diseases induce referred pain on the body surface where is the same as or adjacent to the location of the spinal segment corresponding to the affected intestinal section. These sensitization regions are related to the locations of acupoints.

The chimeric antigen receptor (CAR) T cell therapy has gradually became a new trend in the treatment of refractory and relapsed hematologic malignancies by developing for 30 years. With the exciting development of genetic engineering, CAR-T technology has subjected to 4 generations of innovation. Structure of CAR-T started from a single signal molecule to 2 or more than 2 co-stimulatory molecules, and then coding the CAR gene or promoter. CAR-T can specifically recognize tumor antigens, and does not be restricted by major histocompatibility complex (MHC), thus making a breakthrough in clinical treatment. In this review, the history, structure and mechanism of action of CAR-T, as well as the current status and challenges of CAR-T immunotherapy in acute lymphoblastic leukemia, acute myeloid leukemia, chronic myeloid leukemia and multiple myeloma are summarized.

ObjectiveTo evaluate the semen quality of the HIV/AIDS male patients after treated by the highly active antiretroviral therapy (HAART) and their potential of transmitting HIV/AIDS and provide some evidence for this cohort of males who wish for parenthood.

METHODSWe collected semen samples from 20 HIV/AIDS male patients who had been treated by HAART for over 6 months and wished for parenthood. We examined sperm concentration, viability and total motility and the percentage of morphologically normal sperm (MNS) using the computer-assisted semen analysis system, measured the HIV-1 RNA loads in the semen by the Cobas Amplicor Monitor test, and counted CD4+ T cells in the peripheral blood by flow cytometry.

RESULTSThe patients were aged 25－40 (30.7 ± 5.05) years. After treated by HAART for 6－26 (14.24 ± 12.26) months, the count of blood CD4+ T cells was significantly increased (341－1 058 ［535.76 ± 212.021］ /μl) in comparison with the baseline (226－965 ［422.38 ± 200.86］ /μl). Compared with the normal value, the semen volume was increased except in 1 case (≥2 ml) while total sperm motility was decreased in 13 cases (≥40%), and so were sperm concentration in 2 cases (≥15 × 106 / ml), sperm viability in 5 (58%), the percentage of progressively motile sperm in 18 (≥32%), and the percentage of MNS in 6 (≤4%). HIV-1 RNA in the peripheral blood was <20 copies/mL in all the cases and that in the seminal plasma was also <20 copies/ml in 18 cases but >20 copies/mL in the other 2 (［4.70 × 101］ and ［2.2 × 102］ copies/ml, respectively). Of the 4 couples that had sex without protective measures for over 6 months, all the 4 female partners exhibited negative HIV antibodies in regular follow-up examinations and 1 achieved spontaneous pregnancy and healthy birth, with negative HIV-1 RNA in both the mother and the baby.

CONCLUSIONSThe HIV RNA level is higher in the semen than in the blood of the HIV/AIDS male patients after HAART, which indicates the potential risk of their semen transmitting HIV/AIDS to their female partners. Their sperm concentration and total sperm motility are lower than the normal value, which suggests a decreased fertility.
