OBJECTIVE: To explore the clinical features and genetic basis for a Chinese pedigree diagnosed with congenital glycosylation disease (CGD). METHODS: Clinical manifestations of two brothers were analyzed. Whole exome sequencing was carried out for the sib pair. Suspected variants were verified by Sanger sequencing. RESULTS: Both the proband and her younger brother were found to carry compound heterozygous variants of the PMM2 gene, which included a known pathogenic mutation of c.395T>C (p.I132T) and a previously unreported c.448-1(delAG) in the 5' end of exon 6 of the gene. CONCLUSION The compound heterozygous variants of the PMM2 gene probably underlay the CGD in the sib pair.

Aldose reductase (AR) is known to play a crucial role in the mediation of diabetic and cardiovascular complications. Recently, several studies have demonstrated that allergen-induced airway remodeling and ovalbumin-induced asthma is mediated by AR. Epalrestat is an aldose reductase inhibitor that is currently available for the treatment of diabetic neuropathy. Whether AR is involved in pathogenesis of pulmonary fibrosis and whether epalrestat attenuates pulmonary fibrosis remains unknown. Pulmonary fibrosis was induced by intratracheal instillation of bleomycin (5 mg/kg) in rats. Primary pulmonary fibroblasts were cultured to investigate the proliferation by BrdU incorporation method and flow cytometry. The expression of AR, TGF-beta1, alpha-SMA and collagen I was analyzed by immunohistochemisty, real-time PCR or western blot. In vivo, epalrestat treatment significantly ameliorated the bleomycin-mediated histological fibrosis alterations and blocked collagen deposition concomitantly with reversing bleomycin-induced expression up-regulation of TGF-beta1, AR, alpha-SMA and collagen I (both mRNA and protein). In vitro, epalrestat remarkably attenuated proliferation of pulmonary fibroblasts and expression of alpha-SMA and collagen I induced by TGF-beta1, and this inhibitory effect of epalrestat was accompanied by inhibiting AR expression. Knockdown of AR gene expression reversed TGF-beta1-induced proliferation of fibroblasts, up-regulation of alpha-SMA and collagen I expression. These findings suggest that AR plays an important role in bleomycin-induced pulmonary fibrosis, and epalrestat inhibited the progression of bleomycin-induced pulmonary fibrosis is mediated via inhibiting of AR expression.

Objective To study the effects and mechanism of calycosin on oxidative stress andβ-cell apoptosis induced by streptozotocin (STZ). Methods RIN-m5F cells were divided into 5 groups:control group, STZ group, STZⅠgroup, STZⅡgroup and STZⅢgroup. The control group did not receive any treatment, while streptozotocin was added to the final concentration of 10 mmol/L in STZ group, STZⅠgroup, STZⅡgroup and STZⅢgroup. After the incubation with STZ for 6 h, calycosin was added to a final concentration of 10, 50 and 100 μmol/L in STZⅠgroup, STZⅡgroup and STZⅢgroup respectively. The cell viability and apoptosis was detected by CCK-8, LDH, caspase 3 and Tunel assay. The intracellular oxidative stress was measured using mitochondrial membrane potential, DCFH-DA, SOD activity and malondialdehyde levels assay. RIN-m5F cells were divided into control group, calycosinⅠgroup, calycosinⅡgroup and calycosinⅢgroup, which were treated with different concentrations (0,10, 50 and 100 μmol/L, respectively) of calycosin. The expression of NF-E2-related factor 2(Nrf2) in RIN- m5F cells was detected by Western blot. The translocation of Nrf2 was detected by immunofluorescence. In RIN-m5F cells were divided intoⅢgroup andⅣgroup,Ⅳgroup was pre-treated with protein kinase C(PKC) inhibitor. The effects of calycosin on Nrf2 translocation, oxidative stress and apoptosis were also observed. Results STZ could induce the accumulation of reactive oxygen species and apoptosis in RIN-m5F cells. Calycosin did not affect normal RIN-m5F cells, whereas it reduced the oxidative stress and apoptosis induced by STZ in a dose-dependent manner. The expression of Nrf2 in RIN-m5F cells was not affected by calycosin, whereas it promoted the translocation of Nrf2 into nucleus. The ability of calycosin promoting Nrf2 translocation was decreased after PKC inhibitor treatment, and PKC inhibitor could also significantly attenuate the anti-oxidant and anti-apoptotic ability of calycosin. Conclusions This study shows that calycosin may play an anti-oxidative and anti-apoptotic role by activating PKC to promote Nrf2 translocation, which is expected to be used as a new clinical drug for the prevention and treatment of diabetes mellitus.

Objective To explore the clinical and genetic characteristics of complex glycerol kinase deficiency (GKD). Methods The clinical data of 2 cases of complex GKD were analyzed and the related literatures were reviewed. Results Both cases were male onset in neonatal period, and had hypocorticalism (hyponatremia, hyperkalemia, dehydration), hypercreatine kinasemia, and pseudotriglyceridemia. Gene detection suggested that there was gene deletion in chromosome Xp21 region. In the follow-up, one case had good control of the disease and one died of infection. Conclusions Complex GKD is an X-linked recessive hereditary disease. It is rare and complicated, and is easily misdiagnosed. Early diagnosis and treatment are beneficial to improve the prognosis.

Lenvatinib mesylate (LF), a multi-target tyrosinase inhibitor mainly used in the treatment of a variety of cancers, has low oral bioavailability mainly due to its gelation during the dissolution process. In the current study, in order to enhance dissolution and eliminate gelation of LF, a supramolecular coamorphous system of LF-baicalein (BAI) (molar ratio, 1∶1) was prepared by rotary evaporation and characterized by PLM, PXRD, DSC and FTIR. Results indicated the formation of coamorphous system with a single Tg of 118 °C. Different from original LF crystal, no gelation phenomenon was observed during the dissolution of coamorphous LF-BAI. In addition, the dissolution rate of LF was increased by 2.2-fold after coamorphization. Meanwhile, the dissolution rate of the co-former BAI was also enhanced by more than 25.4-fold. Stability test showed that the prepared coamorphous system had a good physical stability for at least 90 days under 25 °C/ 60%RH and 40 °C /75%RH conditions.

OBJECTIVE: To investigate the association of myocardial blood flow (MBF) quantified by dynamic computed tomography (CT) myocardial perfusion imaging (MPI) with troponin level and left ventricle (LV) function in patients with ST-segment elevated myocardial infarction (STEMI). MATERIALS AND METHODS: Thirty-five STEMI patients who successfully had undergone reperfusion treatment within 1 week of their infarction were consecutively enrolled. All patients were referred for dynamic CT-MPI. Serial high-sensitivity troponin T (hs-TnT) levels and left ventricular ejection fraction (LVEF) measured by echocardiography were recorded. Twenty-six patients with 427 segments were included for analysis. Various quantitative parameters derived from dynamic CT-MPI were analyzed to determine if there was a correlation between hs-TnT levels and LVEF on admission and again at the 6-month mark. RESULTS: The mean radiation dose for dynamic CT-MPI was 3.2 ± 1.1 mSv. Infarcted territories had significantly lower MBF (30.5 ± 7.4 mL/min/100 mL versus 73.4 ± 8.1 mL/min/100 mL, p < 0.001) and myocardial blood volume (MBV) (2.8 ± 0.9 mL/100 mL versus 4.2 ± 1.1 mL/100 mL, p = 0.044) compared with those of reference territories. MBF showed the best correlation with the level of peak hs-TnT (r = −0.682, p < 0.001), and MBV showed a moderate correlation with the level of peak hs-TnT (r = −0.437, p = 0.026); however, the other parameters did not show any significant correlation with hs-TnT levels. As for the association with LV function, only MBF was significantly correlated with LVEF at the time of admission (r = 0.469, p = 0.016) and at 6 months (r = 0.585, p = 0.001). CONCLUSION: MBF quantified by dynamic CT-MPI is significantly inversely correlated with the level of peak hs-TnT. In addition, patients with lower MBF tended to have impaired LV function at the time of their admission and at 6 months.

Hypereosinophilia (HE) is a kind of hematology disorder affecting multiple organs. Multiple studies demonstrated that HE was correlated with ischemic stroke, and it could be a rare and reversible cause for ischemic stroke. Therefore, more and more concerns have been concentrated by neurologists in recent years. Based on the research data, the definition, typical characteristics, possible mechanism, diagnosis and treatment principles of HE related ischemic stroke were summarized systematically, in order to provide possible personalized treatment strategies for this disease.

OBJECTIVE: To study the prevalence and clinical characteristics of decreased myocardial blood flow (MBF) quantified by dynamic computed tomography (CT) myocardial perfusion imaging (MPI) in symptomatic patients without in-stent restenosis. MATERIALS AND METHODS: Thirty-seven (mean age, 71.3 ± 10 years; age range, 48–88 years; 31 males, 6 females) consecutive symptomatic patients with patent coronary stents and without obstructive de novo lesions were prospectively enrolled to undergo dynamic CT-MPI using a third-generation dual-source CT scanner. The shuttle-mode acquisition technique was used to image the complete left ventricle. A bolus of contrast media (50 mL; iopromide, 370 mg iodine/mL) was injected into the antecubital vein at a rate of 6 mL/s, followed by a 40-mL saline flush. The mean MBF value and other quantitative parameters were measured for each segment of both stented-vessel territories and reference territories. The MBFratio was defined as the ratio of the mean MBF value of the whole stent-vessel territory to that of the whole reference territory. An MBFratio of 0.85 was used as the cut-off value to distinguish hypoperfused from non-hypoperfused segments. RESULTS: A total of 629 segments of 37 patients were ultimately included for analysis. The mean effective dose of dynamic CT-MPI was 3.1 ± 1.2 mSv (range, 1.7–6.3 mSv). The mean MBF of stent-vessel territories was decreased in 19 lesions and 81 segments. Compared to stent-vessel territories without hypoperfusion, the mean MBF and myocardial blood volume were markedly lower in hypoperfused stent-vessel territories (77.5 ± 16.6 mL/100 mL/min vs. 140.4 ± 24.1 mL/100 mL/min [p < 0.001] and 6.4 ± 3.7 mL/100 mL vs. 11.5 ± 4 mL/100 mL [p < 0.001, respectively]). Myocardial hypoperfusion in stent-vessel territories was present in 48.6% (18/37) of patients. None of clinical parameters differed statistically significantly between hypoperfusion and non-hypoperfusion subgroups. CONCLUSION: Decreased MBF is commonly present in patients who are symptomatic after percutaneous coronary intervention, despite patent stents and can be detected by dynamic CT-MPI using a low radiation dose.

Objective:To explore the application effect of perioperative peripheral venous pathway chain management scheme in surgical patients.Methods:This study was a historical control study. Using the convenient sampling method, surgical patients who were admitted to Peking University People's Hospital from March to July 2018 were selected as the control group and they were given routine intravenous care. The surgical patients who were admitted from January to June 2019 were selected as the observation group, and they were given perioperative peripheral venous pathway chain management scheme on the basis of the control group. A total of 528 patients were included, including 5 cases of detachment due to patient change of treatment plan, 5 cases of detachment due to temporary cancellation of operation, and 3 cases of detachment without relevant data collected by puncture inspection during hospitalization. Finally, 515 patients were included, including 247 cases in the control group and 268 cases in the observation group. A total of 589 indwelling needles were indwelled in the observation group and 474 indwelling needles in the control group. The indwelling needle site, indwelling needle model, re-catheterization rate, indwelling time, failure rate of indwelling needles, venipuncture consumables costs and nursing costs were compared between the two groups.Results:The number of indwelling needles in the medial forearm vein and lateral forearm vein in the observation group was more than that in the control group, and the differences were statistically significant ( P<0.01) . The number of indwelling 20 G indwelling needles in the observation group was more than that in the control group, and the number of indwelling 18 G indwelling needles in the observation group was less than that in the control group, and the differences were statistically significant ( P<0.01) . The failure rate of indwelling needle, re-catheterization rate, venipuncture consumables costs and nursing costs in the observation group were lower than those in the control group, and the differences were statistically significant ( P<0.01) . Conclusions:The perioperative peripheral venous access chain management scheme can effectively reduce the failure rate andre-catheterization rate of indwelling needles in surgical patients, reduce related costs, and improve the quality of peripheral venous care.
