Abstract
Objective: To evaluated the safety and feasibility of dissection of lymph nodes posterior to right recurrent laryngeal nerve (ⅥB compartment) in endoscopic thyroidectomy through gasless axillary posterior approach. Methods: A total of 350 cases with right lobe papillary thyroid carcinoma (PTC) who underwent endoscopic lobectomy, isthmusectomy and central compartment neck dissection via gasless axillary posterior approach based at the Department of General Surgery, Nanfang Hospital, Southern Medical University from June 2020 to December 2022 were retrospectively analyzed. Summarize the clinical, pathological characteristics, and postoperative complications of the patients. SPSS 25.0 was used for statistical analysis of the data. Results: All 350 patients underwent endoscopic surgery successfully, with no conversion to open surgery. There were 303 females and 47 males, with an average age of (36.3±9.2) years. Of those, 287 patients were in pT1a stage, 62 in pT1b stage, and one patient in pT2 stage. There was no T3 or T4 stage patient. The mean numbers of yielded lymph nodes in right central compartment and ⅥB compartment were 8.11±4.65 (range, 1-31) and 2.62±1.86 (range, 1-12), respectively. ⅥB compartment metastasis was detected in 52 (14.86%) of 350 patients. The incidence of transient recurrent laryngeal nerve injury was 0.86%(3/350). Postoperative hematoma occurred in three patients (0.86%). Conclusion: The dissection of ⅥB compartment in endoscopic thyroidectomy through gasless axillary posterior approach is safe and feasible in selected PTC patients.

Abstract
Steroidal glycoalkaloids (SGAs) present in germinated potato tubers are toxic; however, the mechanisms underlying SGA metabolism are poorly understood. Therefore, integrated transcriptome, metabolome, and hormone analyses were performed in this study to identify and characterize the key regulatory genes, metabolites, and phytohormones related to glycoalkaloid regulation. Based on transcriptome sequencing of bud eyes of germinated and dormant potato tubers, a total of 6260 differentially expressed genes were identified, which were mainly responsible for phytohormone signal transduction, carbohydrate metabolism, and secondary metabolite biosynthesis. Two TCP14 genes were identified as the core transcription factors that potentially regulate SGA synthesis. Metabolite analysis indicated that 149 significantly different metabolites were detected, and they were enriched in metabolic and biosynthetic pathways of secondary metabolites. In these pathways, the α-solanine content was increased and the expression of genes related to glycoalkaloid biosynthesis was upregulated. Levels of gibberellin and jasmonic acid were increased, whereas that of abscisic acid was decreased. This study lays a foundation for investigating the biosynthesis and regulation of SGAs and provides the reference for the production and consumption of potato tubers.

Abstract
Objective:To evaluate the feasibility, effectiveness and safety of robot-assisted transaxillary thyroidectomy (RATT).Method: The clinical data of 66 patients undergoing RATT from November 2016 to May 2018 were prospectively collected and analyzed. The average age was (38.61±11.72) years, 57 cases were female and 9 cases were male. Preoperative fine needle aspiration biopsy revealed papillary thyroid carcinoma in 58 cases and follicular thyroid tumor in 8 cases.Result:All the patients successfully completed RATT, and there was no open operation, in which 54 cases of ipsilateral lobetomy and isthmus resection and ipsilateral central lymph node dissection, 8 cases with ipsilateral lobectomy and contralateral near-total lobectomy, and total thyroidectomy with ipsilateral central lymph node dissection and selective neck dissection combined with retroauricular approach in 4 cases. The mean operative time was (124.30±23.41) min, and the average bleeding volume was (17.73±8.28) ml. The mean diameter of thyroid papillary carcinoma was (0.71±6.22) cm, and the postoperative drainage volume was (67.57±25.11) ml. The average postoperative hospitalization time was (3.24±0.81) days. 3 cases (4.5%) had temporary laryngeal nerve palsy after operation, and 1 case (1.5%) had temporary hypocalcemia after operation, all recovered after one month. No postoperative bleeding, subcutaneous emphysema, drinking water cough and permanent hypocalcemia were observed. The average numbers of lymph node dissection in PTC patients were (6.26±4.76), of which 21 cases (36.2%) had lymph node metastasis, postoperative stage T1 54 cases, T2 4 cases, N1a 17 cases, N1b 4 cases. The follow-up time were 1-18 months. The postoperative cosmetic VAS score in January was (9.66±0.54). Ultrasound showed no residual glands in the affected thyroid gland, and there was no recurrence in the local and regional regions.Conclusion:RATT is safe and feasible with good aesthetic effect and can be used as an option for the treatment of thyroid diseases..

Abstract
Objective: To assess the safety and curative effect of gasless endoscopic selective lateral neck dissection (GESLND) via an anterior chest approach for papillary thyroid carcinoma (PTC). Methods: Eighteen patients with PTC(T1-2N1bM0, size<3.0 cm), having GESLND via an anterior chest approach, were included from November 2008 to December 2016. Results: GESLND via an anterior chest approach was successfully performed in all 18 PTC patients (seven male and eleven female) with 83.3% of T1 and 16.7% of T2. The mean operative time of selective lateral neck dissection was 73 min (range 51-92 min). The mean of intraoperative bleeding was 61.1 ml (range 30-120 ml). No major complications occurred except one transient hypoparathyroidism. No residual thyroid glands were detected on ultrasonography and thyroglobulin was(0.73±0.16)ng/ml three months postoperatively. The median of follow-up was 54.5 months (range 6-104 months). No recurrence disease was observed in any patient on ultrasonography, computer tomography, thyroglobulin or selective iodine-131 scan during the follow-up period. The cosmetic result and functional preservation was excellent, when the assessments were performed three months postoperatively. Conclusion: GESLND via an anterior chest approach is feasible and safe for selected PTCs, with superior appearance.

Abstract
Of the two cultivated species of allopolyploid cotton, Gossypium barbadense produces extra-long fibers for the production of superior textiles. We sequenced its genome (AD)2 and performed a comparative analysis. We identified three bursts of retrotransposons from 20 million years ago (Mya) and a genome-wide uneven pseudogenization peak at 11–20 Mya, which likely contributed to genomic divergences. Among the 2,483 genes preferentially expressed in fiber, a cell elongation regulator, PRE1, is strikingly At biased and fiber specific, echoing the A-genome origin of spinnable fiber. The expansion of the PRE members implies a genetic factor that underlies fiber elongation. Mature cotton fiber consists of nearly pure cellulose. G. barbadense and G. hirsutum contain 29 and 30 cellulose synthase (CesA) genes, respectively; whereas most of these genes (>25) are expressed in fiber, genes for secondary cell wall biosynthesis exhibited a delayed and higher degree of up-regulation in G. barbadense compared with G. hirsutum, conferring an extended elongation stage and highly active secondary wall deposition during extra-long fiber development. The rapid diversification of sesquiterpene synthase genes in the gossypol pathway exemplifies the chemical diversity of lineage-specific secondary metabolites. The G. barbadense genome advances our understanding of allopolyploidy, which will help improve cotton fiber quality.

Abstract
Carbon dioxide mass transfer is a key factor in cultivating micro-algae except for the light limitation of photosynthesis. It is a novel idea to enhance mass transfer with the cyclic procedure of absorbing CO(2) with a high performance alkaline abosorber such as a packed tower and regenerating the alkaline solution with algal photosynthesis. Hence, the algae with high affinity for alkaline condition must be purified. In this study, a hot spring alga (HSA) was purified from an alkaline hot spring (pH 9.3, 62 degrees C) in Taiwan and grows well over pH 11.5 and 50 degrees C. For performance of HSA, CO(2) removal efficiencies in the packed tower increase about 5-fold in a suitable growth condition compared to that without adding any potassium hydroxide. But ammonia solution was not a good choice for this system with regard to carbon dioxide removal efficiency because of its toxicity on HSA. In addition, HSA also exhibits a high growth rate under the controlled pHs from 7 to 11. Besides, a well mass balance of carbon and nitrogen made sure that less other byproducts formed in the procedure of carboxylation. For analysis of some metals in HSA, such as Mg, Mn, Fe, Zn, related to the photosynthesis increased by a rising cultivated pH and revealed that those metals might be accumulated under alkaline conditions but the growth rate was still limited by the ratio of bicarbonate (useful carbon source) and carbonate. Meanwhile, Nannochlopsis oculta (NAO) was also tested under different additional carbon sources. The results revealed that solutions of sodium/potassium carbonate are better carbon sources than ammonia carbonate/bicarbonate for the growth of NAO. However, pH 9.6 of growth limitation based on sodium was lower than one of HSA. The integrated system is, therefore, more feasible to treat CO(2) in the flue gases using the algae with higher alkaline affinity such as HSA in small volume bioreactors.

Abstract
AIM To investigate changes of density of platelet glycoprotein (GP) II b/III a receptor in the perioperative period of gastrectomy in aged rats. METHODS The subtotal gastrectomy operation was performed in 16 adult rats and 16 aged rats respectively. Platelet surface density of GP II b/III receptors were determined by flow cytometric analysis before and 6, 12, 24, 48, 72 hours after operation. RESULTS 6, 12, 24, 48 and 72 hours after operation, the density of GP II b/III a in aged group increased continuously compared with preoperative period (6h, 12, 72: P < 0.05; 24, 48: P < 0.01). CONCLUSION Gastrectomy can lead to an increase of density of platelet GP II b/III a receptor in aged rats.

Abstract
The solid-phase synthesis of a 10,000 member combinatorial library of 1,5-benzodiazepine-2-one derivatives is reported. The 3-amino-1,5-benzodiazepine-2-one scaffold was prepared in solution, and the benzamide nitrogen was used as a point of attachment to the resin. The 5-aniline and 3-amine were then used as points of diversity. A 10,000 member library was synthesized using the Irori directed sorting system, and after analysis of a representative sample from the library, the Irori system was used to remove the compounds of lower purity.

Abstract
It has been speculated that human papillomaviruses (HPV) might be a causative agent of transitional cell carcinoma of the bladder. With the polymerase chain reaction technic, fresh specimens of 53 transitional cell carcinomas of the bladder were examined, and bladder epithelium from 12 patients with hyperplasia of prostate and peripheral blood lymphocytes of 8 normal individuals served as controls. The primers set for HPV-16 and 18 were selected from E6/E7 regions of open reading frames. HPV-16 was positive in 52.8% of the specimens examined, whereas HPV-18 positive in only 3.7%. No controls showed either HPV-16 or 18. Reports on the role of HPVs in carcinogenesis of bladder are scanty and yet there exist conspicuous discrepancies among them. There is a diversity of opinions on the contamination and variation of technical procedures. More work should be done before the relationship between HPV-16 and development of bladder carcinoma can be clarified.

Abstract
A matrix-type transdermal therapeutic system of timolol (TTS-timolol) was well prepared. The patch consisted of backing membrane layer, timolol reservoir layer, pressure sensitive adhesive layer and protective layer. A sensitive and reliable HPLC-UV method for the determination of plasma level of timolol in healthy volunteers was developed. Effective therapeutic plasma level of timolol (4 ng/ml) was attained 4 h after application of the timolol patches and was maintained within 32 h while the patch was removed at 24 h. The pharmacokinetic behavior of this transdermal therapeutic system (TTS)-timolol in human showed zero order absorption and well fitted to a one compartment model. The pharmacokinetic parameters are: Tmax = 18.8 h; Cmax = 11.2 ng/ml; AUC = 265.7 ng/ml.h; Vss = 120.0 L; K = 0.084 h-1. In comparison with the results of oral administration of timolol tablets, TTS-timolol possesses some advantages: stable plasma level, long effective time and convenient administration.

Abstract
Rabbit vascular smooth muscle cells were cultured in various concentrations of endothelin-1 (ET-1) at 37 degrees C for 24 h. The vascular smooth muscle cell cycle distribution was determined by flow cytometry according to DNA content. In the control group, the mitotically active phase (S + G2 + M phase) of vascular smooth muscle cells was 11.94%. In ET-1-cultured smooth muscle cells, the mitotically active phase was 11.69% at a concentration of 1 pM ET-1, whereas the mitotically active phases were 18.98 and 26.91% at concentrations of 0.1 and 10 nM ET-1, respectively. The findings show that ET-1 significantly increased mitotic activity of cultured vascular smooth muscle cells.
