Objective To observe the clinical efficacy and safety of immediate-effect moxibustion combined with massage for the treatment of knee stiffness after knee ligament reconstruction surgery.Methods A total of 138 patients after knee ligament reconstruction surgery were randomly divided into control group and observation group,69 cases in each group.The control group received joint rehabilitation therapy,which included TDP light radiation,joint exercise by continuous passive motion apparatus,contraction and relaxation of quadriceps femoris muscle and ankle pump.The treatment group was given immediate-effect moxibustion combined with massage based on the treatment for the control group.The treatment lasted from postoperative day 3 to 14.Before and after treatment,Lysholm knee joint scores,joint activity scores and activities of daily living(ADL) scores of the two groups were observed.Results After treatment,the Lysholm knee joint scores,joint activity scores and ADL scores of the two group were obviously increased (P < 0.05 or P < 0.01 compared with those before treatment),and the increase in the observation groups was superior to that in the control group,the differences of the alove indexes except for joint activity scores being statistically significant between the two groups (P < 0.05 or P < 0.01).Conclusion Immediate-effect moxibustion combined with massage is effective on preventing knee from postoperative ankylosis after knee ligament reconstruction surgery.

Objective To investigate the role of DWI in differentiating autoimmune pancreatitis ( AIP) from pancreatic cancer ( PC) , and in the therapeutic effect evaluation of AIP.Methods DWI data of 26 cases with AIP , 29 cases with PC and 30 cases with normal pancreas ( NP ) were analyzed retrospectively.The distribution type and signal feature of lesions in cases with AIP or PC were evaluated by Chi-squared test.ADC values were measured and compared among 3 groups by Kruskal-Wallis test.ADC values of AIP and PC were analyzed by using ROC curve to determine the optimal threshold and diagnostic efficiency.ADC values were compared in AIP ( n=15 ) before and after steroid therapy by paired t test.Results Diffuse lesions were detected in 21 cases with AIP and 3 cases with PC, while focal lesions in 5 cases with AIP and 26 cases with PC (χ2 =27.64, P<0.01).On DWI, most of AIP (n=19) and PC (n=24) showed hyper-intense signal, while a few of AIP (n=7) and PC (n =5) showed iso-intense signal (χ2 =0.75, P>0.05).The median ADC values of AIP, PC and NP were 1.15 ×10 -3,1.35 × 10 -3 ,1.59 ×10-3 mm2/s, respectively; and the difference was statistically significant ( H=45.60, P <0.01).ROC analysis yielded an optimal ADC cutoff value of 1.255 ×10 -3 mm2/s (80.8% sensitivity, 79.3%specificity and 0.871 area under curve for the diagnosis of AIP ).ADC values of AIP ( n=15) were markedly increased from the baseline (1.10 ±0.19) ×10 -3 to (1.57 ±0.12) ×10 -3 mm2/s after steroid therapy (t=-10.14, P<0.01).Conclusions DWI may be useful for diagnosing and evaluating the effect of steroid therapy in AIP.ADC values of AIP were significantly lower than those of pancreatic cancer and normal pancreas.After steroid therapy , ADC values were markedly increased in AIP.

【Objective】 To analyze the infectious indicators, HBV s gene mutations and changes in bioinformatics characteristics of HBV DNA+ /HBsAg- blood donor. 【Methods】 A sample of HBV DNA+ /HBsAg- was screened by PCR method, and HBsAg/HBsAb/HBeAg/HBeAb/HBcAb of HBV in the sample were detected by ELISA and chemiluminescence methods. The mutation of the HBVs gene fragment in the sample was sequenced and analyzed, and the bioinformatics analysis was performed using analysis software. 【Results】 The sample showed HBV DNA+, HBsAg-, HBsAb+, HBeAg+, HBeAb- and HBcAb+, with an amino acid unit point mutation (P151L) occurred in the HBV s gene, and the spatial structure changed. 【Conclusion】 The spatial structural changes in the gene sequence of HBVs may be the reason for the appearance of serological HBsAg-/HBsAb+ /HBV DNA+ in the test results.

Idiopathic oligoasthenospermia (IO) has been increasingly emphasized in the diagnosis and treatment of male infertility. Oxidative stress damage directly affects sperm quality and spermatogenesis, constituting a major causative factor of IO. Firstly, due to its high content of polyunsaturated fatty acids, the sperm plasma membrane is highly sensitive to reactive oxygen species (ROS), leading to lipid peroxidation accumulation and even inducing ferroptosis. Secondly, deficient downstream key proteins in the base excision repair pathway render sperm unable to repair extensive DNA oxidative damage under oxidative stress. Simultaneously, under oxidative stress, the apoptotic pathway of sperm is cascade-activated, causing rapid loss of motility. ROS further disrupts the hypothalamic-pituitary-gonadal axis, inhibiting testosterone production and ultimately affecting spermatogenesis. Wuzi Yanzongwan,in line with traditional Chinese medicine theory of treating IO through "nourishing kidney essence and harmonizing Yin and Yang", clinically demonstrates its ability to improve sperm morphology, count, and motility, thereby enhancing male fertility. The research on the pharmacological constituents of Wuzi Yanzongwan primarily involves establishing a characteristic spectrum of Chinese medicine to achieve quality control and exploring the pharmacology of effective components. Studies have found that its main active ingredients consist of flavonoids and phenylpropanoids. Specifically, compounds such as hyperin, acteoside, kaempferol, and schisandrin A are identified as the primary active substances and quality control components. These compounds exhibit strong antioxidant activity and have been partly applied in research related to reproductive endocrine disorders. Tripterygium glycoside is primarily used for modeling of oxidative stress-induced IO. It leads to the accumulation of various lipid peroxides in testicular tissues and concurrently compromises the body's antioxidant capacity. Mechanistic studies have found that Wuzi Yanzongwan can inhibit elevated ROS levels in IO models and enhance the body's antioxidant capacity, thereby ameliorating inflammation, suppressing cell apoptosis, promoting testosterone production, and ultimately alleviating the decline in sperm quality and spermatogenesis caused by oxidative stress.

Retinoid X receptor α (RXRα) and its N-terminally truncated version tRXRα play important roles in tumorigenesis, while some RXRα ligands possess potent anti-cancer activities by targeting and modulating the tumorigenic effects of RXRα and tRXRα. Here we describe NSC-640358 (N-6), a thiazolyl-pyrazole derived compound, acts as a selective RXRα ligand to promote TNFα-mediated apoptosis of cancer cell. N-6 binds to RXRα and inhibits the transactivation of RXRα homodimer and RXRα/TR3 heterodimer. Using mutational analysis and computational study, we determine that Arg316 in RXRα, essential for 9-cis-retinoic acid binding and activating RXRα transactivation, is not required for antagonist effects of N-6, whereas Trp305 and Phe313 are crucial for N-6 binding to RXRα by forming extra π-π stacking interactions with N-6, indicating a distinct RXRα binding mode of N-6. N-6 inhibits TR3-stimulated transactivation of Gal4-DBD-RXRα-LBD by binding to the ligand binding pocket of RXRα-LBD, suggesting a strategy to regulate TR3 activity indirectly by using small molecules to target its interacting partner RXRα. For its physiological activities, we show that N-6 strongly inhibits tumor necrosis factor α (TNFα)-induced AKT activation and stimulates TNFα-mediated apoptosis in cancer cells in an RXRα/tRXRα dependent manner. The inhibition of TNFα-induced tRXRα/p85α complex formation by N-6 implies that N-6 targets tRXRα to inhibit TNFα-induced AKT activation and to induce cancer cell apoptosis. Together, our data illustrate a new RXRα ligand with a unique RXRα binding mode and the abilities to regulate TR3 activity indirectly and to induce TNFα-mediated cancer cell apoptosis by targeting RXRα/tRXRα.
