Aortic valve calcification (AVC) is a pathological process correlated with multiple disease causes and actively regulated by cardiac valve cells. In this study, porcine aortic valve myofibroblasts cultured in vitro were treated with 50 μg z L(-1) of pathological factor tumor necrosis factor α (TNF-α). Tanshinone II A (TSN) with the concentration of 50 mg x L(-1) and TNF-α were combined in incubating cells for 72 h (3 d) and 120 h (5 d). The Western blotting and Real-time PCR were adopted to detect the changes in smooth muscle α actin (α-SMA), bone morphogenetic protein 2 ( BMP2), alkaline phosphatase (ALP) in cells, and expressions of key effect proteins GSK-3β and β-catenin on Wnt/β-catenin signal pathway. According to the findings, TNF-α can significantly increase the expression of myofibroblasts α-SMA and add the transformation activity to them, with nearly no expression of BMP2, ALP and mRNA in the control group and the TSN group but significant increase in their expressions in the TNF-α group (P < 0.01), which showed osteoblast-like phenotype. Moreover, TNF-α down-regulated the expression of up-streaming regulator GSK-3β and mRNA expression (P < 0. 01) , notably increased the expression of key effect protein β-catenin, but with no significant difference in mRNA with the control group and the TSN group. The result demonstrated that TSN showed a certain inhibitory effect on TNF-α's pathological impact (P < 0.05) in a time-dependent manner. Inflammatory factor TNF-α may promote the transformation of aortic valvular myofibroblasts to osteoblast-like phenotype by activating Wnt/β-catenin signal pathway in aortic valvular myofibroblasts, so as to cause AVC. Tanshinone II A can have a preventive effect in AVC by activating GSK-3β proteins and regulating signal transduction of Wnt/β-catenin signal pathway.

OBJECTIVETo screen for genetic mutations in families featuring non-syndromic hearing loss.
METHODSSixteen families with non-syndromic hearing loss were interviewed to identify medical histories by a questionnaire. Audiological and neurological examinations were conducted for all families. Coding regions of GJB2 and 12S rRNA genes were amplified and sequenced.
RESULTSOf the 17 patients with sensorineural hearing loss, 3 were homozygous mutation for GJB2 235 delC, 1 was 235 delC heterozygous mutation, 1 was 235 delC+299_300 delAT compound heterozygous mutation, and 6 were 79G>A+341G>A heterozygosis in cis mutation. No 1555A>G mutation of mitochondrial DNA (mtDNA) was found in the 16 families.
CONCLUSIONThe incidence of mtDNA 12S rRNA 1555A>G mutation in Jiangsu province may be lower than the average across China. Mutations of GJB2 genes may account for as much as 64.7% of non-syndromic hearing loss in this study. Screening for such mutations and genetic counseling may play an important role in the prevention of hereditary hearing loss.

OBJECTIVETo study expression of mutant p53 protein in workers occupationally exposed to benzidine and bladder cancer patients.
METHODSMutant p53 protein in serum from the workers occupationally exposed to benzidine and bladder cancer patients were determined with Immuno-PCR, while exfoliated urothelial cells in the urine samples were classified with Papanicolau grading.
RESULTSPositive rate of mutant p53 protein increased with the exposed intensity index in workers occupationally exposed to benzidine. The positive rate of mutant p53 protein in bladder cancer patients (83.3%) was significantly higher than that in the group 1 of exposed intensity index. The average scanning integrals of PCR amplified band in the group of bladder cancer patients and group 2 of exposed intensity index were both higher than that in the group 1 significantly. Workers in the groups of different exposed intensity indices were further stratified according to Papanicolau grades. In the group 2 of exposed intensity index, the average scanning integrals of PCR amplified band in the stratum of Papanicolau grade II and III were significantly higher than that in the strata of Papanicolau grade I. And in the group 3 of exposed intensity index, the positive rate of mutant p53 protein in the strata of Papanicolau grade III was higher than that in the strata of Papanicolau grade I significantly.
CONCLUSIONThe increase of exposed intensity may not only result in the positive rate of mutant p53 protein, but also the quantity of mutant p53 protein in serum within the low range of benzidine exposure. Once the exposed intensity was beyond that spectrum, the positive rate of mutant p53 protein in serum and the average scanning integrals of PCR amplified band were no longer enhanced with the increase of exposed intensity. There was tight correlation between Papanicolau grade of exfoliated urothelial cells and the positive rate or the quantity of mutant p53 protein for the higher benzidine exposure intensity.

AIM: To compare the clinical efficacy, vault, and rotational stability of horizontal, oblique, and vertical implantation of Toric implantable collamer lens(TICL).METHODS: Retrospective cohort study. A total of 92 cases(120 eyes)who underwent TICL implantation from July 2018 to March 2022 and had regular follow-up for at least 1 a postoperatively(1 d, 1 wk, 1, 3, 6 mo, and 1 a)at Wuhan Bright Eye Hospital were collected. The patients were divided into three groups, with 34 cases(45 eyes)in horizontal implantation group, 25 cases(29 eyes)in oblique implantation group(29 cases), and 33 cases(46 eyes)in vertical implantation group. Uncorrected distance visual acuity(UDVA), corrected distance visual acuity(CDVA), diopters, vault, and rotation angle(deviation of the actual axis of TICL from the expected axis).RESULTS: All surgeries were uneventful, and there were no complications such as infection, secondary glaucoma, or cataract opacity. Safety and efficacy of the surgery: the CDVA of the three groups of patients was better than or equal to the preoperative CDVA at 1 a postoperatively, and there was no statistically significant differences in postoperative UDVA and CDVA of the three groups(P>0.05). The safety index at 1a postoperatively was 1.34±0.21, 1.34±0.17, and 1.31±0.18 for the horizontal, oblique, and vertical groups, respectively. The efficacy index was 1.26±0.21, 1.33±0.18, and 1.27±0.16 for the three groups, respectively, both with no statistically significant differences(P>0.05). Vault: there was a significant difference in postoperative vault among the three groups(P=0.003), with the vertical group having the lowest vault, followed by the horizontal group and the oblique group. The vaults at different follow-up time points within each group showed significant differences(P<0.001), and all decreased over time. Residual astigmatism: there was no significant difference in residual astigmatism among the three groups(P=0.130), but there were differences at different follow-up time points within each group(P<0.001). Rotation angle: no significant differences in rotation angle were observed among the three groups(P=0.135), but there were differences at different follow-up time points within each group(P<0.001).CONCLUSION: The implantation of TICL in different orientations has good safety and efficacy, the postoperative rotational stability is good, and the appropriate angle can be selected to implant TICL according to the clinical situation.

In the current study, schisandrin B(SchB)-loaded F127 modified lipid-polymer hybrid nanoparticles(SchB-F-LPNs) were developed to improve the inhibition of breast cancer lung metastasis. Modified nanoprecipitation method was used to prepare SchB-F-LPNs. The nanoparticles were spherical in shape with shell-core structure by TEM observation. SchB-F-LPNs showed a mean particle size of(234.60±6.11) nm with zeta potential of(-5.88±0.49) mV. XRD results indicated that SchB existed in the nanoparticles in an amorphous state. The apparent permeability coefficient through porcine mucus of F-LPNs was 1.43-fold of that of LPNs as shown in the in vitro mucus penetration study. The pharmacokinetics study showed that the C_(max) of SchB was(369.06±146.94) μg·L~(-1),(1 121.34±91.65) μg·L~(-1) and(2 951.91±360.53) μg·L~(-1) respectively in SchB suspensions group, SchB-LPNs group and SchB-F-LPNs group after oral administration in rats. With SchB suspensions as the reference formulation, the relative bioavailability of SchB-F-LPNs was 568.60%. SchB-F-LPNs inhibited the morphological change during transforming growth factor-β1(TGF-β1)-induced epithelial-mesenchymal transition. In addition, SchB-F-LPNs significantly decreased the number of metastatic pulmonary nodules in 4 T1 tumor-bearing mice, suggesting that SchB-F-LPNs may inhibit the metastasis of breast cancer. These results reveal the promising potential of SchB-F-LPNs in treatment of breast cancer lung metastasis.

OBJECTIVETo determine whether additional Chinese medicine (CM) could prolong survival and improve the quality of life (QOL) in patients with advanced non-small cell lung cancer (NSCLC) compared with Western medicine (WM) alone.
METHODSThis was a multicenter, prospective cohort study. A total of 474 hospitalized patients with stage III-IV NSCLC were recruited and divided into 2 groups. Patients in the WM group received radiotherapy, chemotherapy, and optimal supportive therapy according to the National Comprehensive Cancer Network (NCCN) guidelines. In the integrative medicine (IM) group, individualized CM (Chinese patent medicines and injections) and WM were administered. The primary end point was overall survival, and the secondary end points were time to disease progression, adverse events, and QOL. Follow-up clinical examinations and chest radiography were performed every 2 months.
RESULTSThe median survival was 16.60 months in the IM group and 13.13 months in the WM group (P<0.01). The incidences of loss of appetite, nausea, and vomiting in the IM group were significantly lower than those in the WM group (P<0.05). The QOL based on Functional Assessment of Cancer Therapy-Lung in the IM group was markedly higher than that in the WM group at the fourth course (P<0.05).
CONCLUSIONSAdditional CM may prolong survival and improve the QOL patients with NSCLC. The adverse effects of radio- and chemotherapy may be attenuated as CM is used in combination with conventional treatments.
