Objective To investigate the value of clinical use of laparoscopy combined with choledochoscopy in treatment of cholecystolithiasis complicated with choledocholithiasis.Methods Of 120 patients suffering from cholecystolithiasis combined with choledocholithiasis,56 patients underwent laparoscopic cholecystectomy together with choledocholithotomy and T-tube drainage(LCTD),and 64 patients received routine cholecystectomy and choledocholithotomy plus T-tube drainage by laparotomy.Postoperative administration of analgesics,wound infection,recovery of function of gastrointestinal tract(RFGI),and hospital stay were compared between the two groups.Results In both groups,there were no severe complications.Wound infection rate was 12.5 %,average hospital stay was(14.9?3.1) d,and RFGI was(26.1?8.6) h in routine operation group;while in LCTD group,there was no wound infection occurred,hospital stay was(5.8?1.4) d and RFGI was(10.6?3.4) h.There were significant difference in postoperative recovery conditions between the two groups(P

The effects of hepatic ischemia/reperfusion (1/R) injuries on hepatocellular viability and store-operated calcium current (Isoc) in isolated rat hepatocytes and the effects of 2-APB on store-operated calcium current (Isoc) in isolated rat hepatocytes after hepatic ischemia/reperfusion injuries were studied. Hepatic ischemia and reperfusion injury model was established and whole cell patch-clamp techniques were used to investigate the effects of 2-APB on Isoc. The results showed that ischemia/reperfusion injuries could significantly reduce hepatocellular viability and further increase Isoc in hepatocytes and 2-APB (20, 40, 60, 80, 100 micromol/L,) produced a concentration-dependent decrease of Isoc with IC50 value of 64. 63 +/- 10.56 micromol/L, (n = 8). It was concluded that ischemia/reperfusion injuries could reduce hepatocellular viability, probably through increased Isoc in hepatocytes and 2-APB had a protective effect on ischemia/reperfusion-induced liver injury, probably though inhibiting Isoc.

Objective To evaluate the clinical significance of transvaginal color Doppler ultrasound for the differential diagnosis of benign and malignant ovarian cysts. Methods Patients who were diagnosed with clinically suspected or palpable adnexal masses and underwent gray-scale ultrasonography, transvaginal color Doppler ultrasonography, and ultrasound-guided fine-needle aspiration cytology (FNAC) during the period from 2018 to 2021 were enrolled in this study. The pulsatility index (PI) and resistance index (RI) were estimated, and an ovarian cyst with the lowest PI value of < 1.0 or the lowest RI value of < 0.4 was considered as malignant. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of gray-scale ultrasound and transvaginal color Doppler ultrasound for the differential diagnosis of benign and malignant ovarian cysts were estimated with FNAC as the gold standard. Results A total of 180 patients with ovarian cysts were recruited, and FNAC revealed that 81 of them had malignant lesions and 99 of them had benign lesions. The transvaginal color Doppler ultrasonograms showed that 75 patients (92.59%) with malignant lesions had blood-flow signals in their cysts and 42 patients (42.24%) with benign lesions had blood-flow signals in their cysts, with a significant difference in the proportion between the two groups (χ² = 49.29, P < 0.01). Among the 75 patients with blood-flow signals in malignant ovarian cysts, 75 had PI < 1.0 and 24 had RI < 0.4; among the 42 patients with blood-flow signals in benign ovarian cysts, 15 had PI < 1.0 and no one had RI < 0.4; there were significant differences in the proportions of PI < 1.0 and RI < 0.4 between the two groups (χ² = 62.68, P < 0.01; χ² = 16.91, P < 0.01). In addition, compared with the combination of gray-scale ultrasound and transvaginal color Doppler ultrasound, gray-scale ultrasound alone had significantly lower sensitivity (51.85% vs 81.48%; χ² = 16.00, P < 0.01), specificity (75.76% vs 93.94%; χ² = 12.73, P < 0.01), PPV (63.64% vs 91.67%; χ² = 15.90, P < 0.01), and NPV (65.79% vs 86.11%; χ² = 12.44, P < 0.01) for the differential diagnosis of benign and malignant ovarian cysts. Conclusion Gray-scale ultrasound is effective for diagnosing ovarian cysts; however, gray-scale ultrasound combined with transvaginal color Doppler ultrasound can improve the differential diagnosis of benign and malignant ovarian cysts.

ObjectiveProteomics was used to investigate the protein differences between porcine cardiac blood（PCB） and porcine blood（PB） from Menghe medical school and to compare the effects of both on the microglial inflammation of Salviae Miltiorrhizae Radix et Rhizoma（DS）. MethodNanoliquid chromatography-quadrupole orbitrap mass spectrometry（nLC-MS/MS） and bioinformatics were utilized to compare the proteomic differences of PCB and PB in simulated gastrointestinal digestion. Furthermore， Western blot was used to verify the contents of some shared proteins and differential proteins identified in PCB and PB. In addition， BV2 neuroinflammation model constructed by corticosterone（CORT） and lipopolysaccharide（LPS） was applied to detect the intervention effects of PCB and PB on the levels of tumor necrosis factor（TNF）-α and interleukin（IL）-6 in BV2 inflammatory cells of DS. ResultA total of 69 common proteins and 68 differential proteins were identified in PCB and PB， among which the common proteins included transferrin（Tf） with brain-targeting effect， and the differential proteins in the two were 41 and 27， respectively. Western blot validation showed that the difference in the content of the same protein Tf between PCB and PB was not statistically significant， while the difference in the contents of the specific proteins of creatine kinase M and heart-type fatty acid binding protein（H-FABP） were statistically significant（P<0.05）. Moreover， in vitro experimental studies revealed that compared with the same concentration of DS group， in addition to the 100 mg·L^-1 PB-DS group， PCB-DS and PB-DS groups could significantly inhibit the levels of TNF-α and IL-6 in BV2 inflammatory cells（P<0.05， P<0.01）， and PCB-DS group had more significant anti-inflammatory effect than PB-DS group with the same concentration（P<0.05， P<0.01）. ConclusionBoth of PCB and PB can enhance the inhibitory effect of DS on the release of inflammatory factors， thus playing a neuroprotective role， and PCB promotes DS inhibition more significantly， which may be due to the existence of the two involved in energy metabolism-related differential proteins， which can lay a foundation for revealing the scientific connotation of the processing of PCB-DS and PB-DS.

ObjectiveTo analyze the correlation between 11 small molecule active components and 1 protein component of characteristic processed products with porcine cardiac blood and other products of Salviae Miltiorrhizae Radix et Rhizoma（SMRR） from Menghe medical school and anti-cerebral ischemic oxidative damage， and to identify its key component markers of characteristic processed products with porcine cardiac blood for anti-cerebral ischemic oxidative damage. MethodHigh performance liquid chromatography（HPLC） was established to simultaneously determine the contents of 11 active ingredients in SMRR and its processed products［processed with porcine cardiac blood， porcine blood， wine and transferrin（Tf） in porcine cardiac blood］， and the content of Tf in different processed products of SMRR was detected by enzyme-linked immunosorbent assay（ELISA）. Furthermore， A zebrafish ischemic stroke model was constructed to evaluate the effects of different processed products of SMRR on the behavioral trajectory of cerebral ischemic zebrafish， the neuronal damage of transgenic zebrafish Tg（elavl3：eGFP） brain， as well as the levels of malondialdehyde（MDA） and superoxide dismutase（SOD） in the brain tissues. The hippocampal neurons oxygen-glucose deprivation/reoxygenation（OGD/R）-induced ischemia-hypoxia model was constructed to evaluate the effects of different processed products of SMRR on oxidative damage of neuronal cells by taking lactate dehydrogenase（LDH）， reactive oxygen species（ROS）， MDA and SOD as indexes. Finally， principal component analysis（PCA）， partial least squares-discriminant analysis（PLS-DA） and Spearman correlation analysis were used to analyze the 11 small molecule active components and 1 protein component with efficacy indicators， in order to screen the key components of the characteristic processed products with porcine cardiac blood for cerebral ischemic oxidative damage. ResultCompared with the raw products， the contents of water-soluble and fat-soluble components in processed products of SMRR increased to different degrees， while the content of salvianolic acid A decreased. Compared with the wine-processed products， the contents of salvianolic acid B， danshensu， rosmarinic acid and other components in the porcine cardiac blood-processed products， porcine blood-processed products， Tf-processed products were increased， while the content of salvianolic acid A was decreased. ELISA results showed that there was no significant difference in Tf content between the porcine cardiac blood-processed products， porcine blood-processed products， Tf-processed products. Pharmacological results showed that different processed products of SMRR could improve the behavioral deficits， brain neuronal injury and oxidative stress after ischemic stroke in zebrafish， and the effect of the porcine cardiac blood-processed products was most pronounced. PCA results showed that salvianolic acid B， salvianolic acid A， rosmarinic acid， lithospermic acid， danshensu， tanshinone Ⅱ_A， caffeic acid， cryptotanshinone and tanshinone Ⅰ were the main contributing components of SMRR and its processed products. And the results of correlation analysis showed that the contents of cryptotanshinone， rosmarinic acid， caffeic acid， dihydrotanshinone Ⅰ， salvianolic acid B， tanshinone Ⅱ_A and tanshinone Ⅰ were negatively correlated with MDA level in zebrafish brain tissue， while the contents of lithospermic acid， protocatechuic aldehyde， rosmarinic acid， dihydrotanshinone Ⅰ， salvianolic acid B and Tf were positively correlated with SOD level， and the contents of rosmarinic acid， caffeic acid， dihydrotanshinone Ⅰ， salvianolic acid B， tanshinone Ⅱ_A， tanshinone Ⅰ， danshensu， Tf were positively correlated with neuronal fluorescence intensity in the zebrafish brain. And the contents of lithospermic acid， protocatechuic aldehyde， rosmarinic acid， dihydrotanshinone Ⅰ， salvianolic acid B， tanshinone Ⅱ_A and Tf were negatively correlated with LDH， ROS and MDA levels and positively correlated with SOD level. ConclusionThere are differences in the anti-ischemic oxidative damage effects of SMRR and its different processed products， among which the porcine cardiac blood-processed products has the strongest effect on improving oxidative damage， which may be related to the content changes of salvianolic acid B， danshensu， rosmarinic acid and other components. This study can provide a basis for clarifying the quality markers of SMRR processed with porcine cardiac blood for cerebral ischemia and elucidating its processing mechanism.

Several studies have evaluated the association between vitamin D receptor, matrix metalloproteinase 3 (MMP-3) polymorphisms and the risk of intervertebral disc degeneration susceptibility. The findings were inconsistent. This meta-analysis aimed to systematically assess the association between vitamin D receptor, MMP-3 polymorphisms and the risk of intervertebral disc degeneration susceptibility. A search of various databases was done covering all papers published until December 31th, 2014. Eight, 4, 3 studies were finally included that addressed the risk of intervertebral disc degeneration susceptibility and vitamin D receptor FokI (rs2228570), ApaI (rs7975232), and MMP-3 (rs731236) polymorphisms, respectively. FokI (f vs. F: summary odds ratio [OR], 1.13; 95% confidence interval [CI], 0.76–1.69; ff vs. FF: OR, 1.02; 95% CI, 0.59–1.77; ff vs. Ff/FF: OR, 1.05; 95% CI, 0.70–1.58), ApaI (a vs. A: OR, 0.73; 95% CI, 0.45–1.19; aa vs. AA: OR, 0.53; 95% CI, 0.22–1.25 p=0.14; aa vs. AA/Aa: OR, 0.69; 95% CI, 0.53–0.89) in the vitamin D receptor gene and MMP3 polymorphisms (5A vs. 6A: OR, 1.92; 95% CI, 0.77–4.80; 5A5A vs. 6A6A: OR, 2.17; 95% CI, 0.75–6.24; 5A5A vs. 5A6A/6A6A: OR, 1.58; 95% CI, 0.72–3.44) were not obviously associated with risk of intervertebral disc degeneration susceptibility. FokI, ApaI polymorphisms in the vitamin D receptor gene and MMP-3 polymorphism are not obvious risk factors for intervertebral disc degeneration susceptibility.

The anti-aging effect of Yang Shou Dan (YSD) was studied. It was shown that YSD could obviously increase the activity of superoxicde dismutase (SOD) in erythrocyte, decrease lipid peroxides (LPO) in serum and in liver tissue and reduce the content of lipofucin in myocardium of mice. It could also prolong the mean life span, the half lethal period and the longest life time of drosophila melanogater. It is suggested that YSD exerts an anti-aging effect to a certain extent.
