Objective To investigate the laparoscopie resection of the adrenal tumor effects and clinical experience. Methods Among the 24 cases of Laparoscopic adrenalectomy tumors, there were 8 cases of adrenal adenoma, 7 cases of pheochromoeytoma and 9 eases primary aldosteronism. Results One ease was transit to open operation, the other 23 were successful,each surgerical time was 40～130 min with an average of 98 rain. Hemorrhage was 50～300 mL, 140 ml average, no blood transfusion. It was 1～2 d after sur- gery to remove drainage tubes, and could take some activities and have fresh flow in the second day. The pa- tients didn't appear complications and discharged after 5～7 d. Follow-up of 6～24 months, there was no recurrence and long-term complications. Conclusion Laparoscopic adrenalectomy has the advantages of minor trauma surgery, less bleeding, good demonstrating, convenient operation, fewer complications and quick recovery.

Objective To observe clinical curative effect of modified total cystectomy and Mainz Ⅱ neobladder. Methods Seventeen patients with bladder neoplasms were treated with modified total cystectomy and Mainz Ⅱ neobladder for urinary diversion. The paries posterior allantois with intestinum rectum and colon sigmoideum were taken 10 cm respectively, split the mesenterium edges, conduplicated and bilayer sutured from the junction of intestinum rectum and colon sigmoideum, bilateral ureters antireflux anastomosed respectively with colon sigmoideum and rectal papilla, then bilayer sutured paries anterior became Mainz allantois. Results There was no surgical mortality. The operative time was 340 ～ 420 mins (mean, 350 mins).Blood transfusion was 400 ～ 800 ml ( mean 600 ml). The follow-up was 4 ～ 18 months, urine and dejecta were shunt, uresis continence was fine and the operation had fewer severe complications. Conclusion Modified total cystectomy and Mainz Ⅱ neobladder to be an effective method for urinary diversion because of its simple operation, fewer severe complications, good uresis continence and high quality of life.

Almost all organisms exhibit ~24-h rhythms, or circadian rhythms, in a plentitude of biological processes. These rhythms are driven by endogenous molecular clocks consisting of a series of transcriptional and translational feedback loops. Previously, we have shown that the inner nuclear membrane protein MAN1 regulates this clock and thus the locomotor rhythm in flies, but the mechanism remains unclear. Here, we further confirmed the previous findings and found that knocking down MAN1 in the pacemaker neurons of adult flies is sufficient to lengthen the period of the locomotor rhythm. Molecular analysis revealed that knocking down MAN1 led to reduced mRNA and protein levels of the core clock gene period (per), likely by reducing its transcription. Over-expressing per rescued the long period phenotype caused by MAN1 deficiency whereas per mutation had an epistatic effect on MAN1, indicating that MAN1 sets the pace of the clock by targeting per.

The current document is based on a consensus reached by a panel of experts from the Chinese Society of Allergy and the Chinese Society of Otorhinolaryngology-Head and Neck Surgery, Rhinology Group. Chronic rhinosinusitis (CRS) affects approximately 8% of Chinese adults. The inflammatory and remodeling mechanisms of CRS in the Chinese population differ from those observed in the populations of European descent. Recently, precision medicine has been used to treat inflammation by targeting key biomarkers that are involved in the process. However, there are no CRS guidelines or a consensus available from China that can be shared with the international academia. The guidelines presented in this paper cover the epidemiology, economic burden, genetics and epigenetics, mechanisms, phenotypes and endotypes, diagnosis and differential diagnosis, management, and the current status of CRS in China. These guidelines—with a focus on China—will improve the abilities of clinical and medical staff during the treatment of CRS. Additionally, they will help international agencies in improving the verification of CRS endotypes, mapping of eosinophilic shifts, the identification of suitable biomarkers for endotyping, and predicting responses to therapies. In conclusion, these guidelines will help select therapies, such as pharmacotherapy, surgical approaches and innovative biotherapeutics, which are tailored to each of the individual CRS endotypes.

Objective To improve the quality standards of Kunxian capsules (KC) and effectively control the product quality. Methods Triptolide, icariin and hypericin were used as the indicator components, to increase or improve the thin layer chromatography (TLC) identification methods of Kunming begonia, epimedium and dodder. Agilent ZORBA SB-C₁₈ (4.6 mm×250 mm, 5 μm) as a chromatographic column, the HPLC method for the determination of triptolide was improved with acetonitrile-0.1% formic acid solution as the mobile phase and 220 nm as the detection wavelength. Results The spots in the TLC method of Kunming begonia, epimedium and dodder has strong specificity, good and clear separation of characteristic spots, negative and no interference. The quantitative analysis of the content of triptolide in KC showed that there is a good linear relationship (r=0.9995) between the mass concentration of triptolide and the peak area in the range of 40.16-502.00 μg/ml, the average recovery was 98.12%, RSD was 8.25%, and the accuracy was good. Conclusion The TLC identification method and HPLC method established in this experiment have strong specificity and good reproducibility, and can effectively control the quality of KC.

Bone regeneration remains a great clinical challenge. Low intensity near-infrared (NIR) light showed strong potential to promote tissue regeneration, offering a promising strategy for bone defect regeneration. However, the effect and underlying mechanism of NIR on bone regeneration remain unclear. We demonstrated that bone regeneration in the rat skull defect model was significantly accelerated with low-intensity NIR stimulation. In vitro studies showed that NIR stimulation could promote the osteoblast differentiation in bone mesenchymal stem cells (BMSCs) and MC3T3-E1 cells, which was associated with increased ubiquitination of the core circadian clock protein Cryptochrome 1 (CRY1) in the nucleus. We found that the reduction of CRY1 induced by NIR light activated the bone morphogenetic protein (BMP) signaling pathways, promoting SMAD1/5/9 phosphorylation and increasing the expression levels of Runx2 and Osterix. NIR light treatment may act through sodium voltage-gated channel Scn4a, which may be a potential responder of NIR light to accelerate bone regeneration. Together, these findings suggest that low-intensity NIR light may promote in situ bone regeneration in a CRY1-dependent manner, providing a novel, efficient and non-invasive strategy to promote bone regeneration for clinical bone defects.
