Objective: To explore the clinical application value of two longitudes three transverses method in the location of the perforator of thoracodorsal artery perforator and deep wound repair. Methods: The retrospectively observational study was conducted. From December 2018 to June 2020, 17 patients with deep wounds who were admitted to the Affiliated Hospital of Zunyi Medical University met the inclusion criteria and were included in this study, including 7 males and 10 females, aged 12 to 72 years. The wound areas of patients after debridement were 7 cm×3 cm to 11 cm×7 cm. Two longitudinal lines were located through the midpoint of the armpit, the posterior superior iliac spine, and the protruding point of the sacroiliac joint, and three transverse lines were located 5, 10, and 15 cm below the midpoint of the armpit between the two longitudinal lines, i.e. two longitudes three transverses method, resulting in two trapezoidal areas. And then the thoracodorsal artery perforators in two trapezoidal areas were explored by the portable Doppler blood flow detector. On this account, a single or lobulated free thoracodorsal artery perforator flap or flap that carrying partial latissimus dorsi muscle, with an area of 7 cm×4 cm to 12 cm×8 cm was designed and harvested to repair the wound. The donor sites were all closed by suturing directly. The number and location of thoracodorsal artery perforators, and the distance from the position where the first perforator (the perforator closest to the axillary apex) exits the muscle to the lateral border of the latissimus dorsi in preoperative localization and intraoperative exploration, the diameter of thoracodorsal artery perforator measured during operation, and the flap types were recorded. The survivals of flaps and appearances of donor sites were followed up. Results: The number and location of thoracodorsal artery perforators located before operation in each patient were consistent with the results of intraoperative exploration. A total of 42 perforators were found in two trapezoidal areas, with 2 or 3 perforators each patient. The perforators were all located in two trapezoid areas, and a stable perforator (the first perforator) was located and detected in the first trapezoidal area. There were averagely 1.47 perforators in the second trapezoidal area. The position where the first perforator exits the muscle was 2.1-3.1 cm away from the lateral border of the latissimus dorsi. The diameters of thoracodorsal artery perforators were 0.4-0.6 mm. In this group, 12 cases were repaired with single thoracodorsal artery perforator flap, 3 cases with lobulated thoracodorsal artery perforator flap, and 2 cases with thoracodorsal artery perforator flap carrying partial latissimus dorsi muscle. The patients were followed up for 6 to 16 months. All the 17 flaps survived with good elasticity, blood circulation, and soft texture. Only linear scar was left in the donor area. Conclusions: The two longitudes three transverses method is helpful to locate the perforator of thoracodorsal artery perforator flap. The method is simple and reliable. The thoracodorsal artery perforator flap designed and harvested based on this method has good clinical effects in repairing deep wound, with minimal donor site damage.

Objective: To analyze density of stromal tumor-infiltrating lymphocytes (sTIL) and expression of lymphocyte-activation gene-3 (LAG-3) protein in advanced gastric adenocarcinomas, and to investigate the correlation of sTIL and LAG-3 with the prognosis in patients with advanced gastric adenocarcinoma. Methods: The clinicopathological characteristics and follow-up data of 260 patients with advanced gastric adenocarcinoma were collected at Fujian Cancer Hospital, from January 2011 to December 2014. The percentage of sTILs was reported semi-quantitatively using histological section evaluation, the LAG-3 protein was detected using immunohistochemistry, and the expression was correlated with the clinicopathological features and patient outcomes. Results: Among the 260 cases, high density of sTIL was detected in 173 cases (66.5%) while LAG-3 high expression was observed in 160 cases (61.5%). These cases were divided into four groups. Group Ⅰ: 48 cases (18.5%) were sTIL low/LAG-3 low; group Ⅱ: 52 cases (20.0%) were sTIL high/LAG-3 low; group Ⅲ: 39 cases (15.0%) were sTIL low/LAG-3 high; group Ⅳ: 121 cases (46.5%) were sTIL high/LAG-3 high. Kaplan-Meier survival analyses showed that patient prognoses were related to age, tumor size, tumor location, Lauren classification, perineural invasion, vascular invasion, TNM staging, postoperative adjuvant chemotherapy and molecular classification (P<0.05). Meanwhile, higher densities of sTIL and higher expression of LAG-3 were associated with better prognosis. Multivariate survival analysis showed age, tumor size, Lauren classification and postoperative adjuvant chemotherapy were independent prognostic factors for patient survival. The results showed a poor prognosis in low-sTIL/low-LAG-3 patients. Conclusions: Compared with low density of sTIL and low expression of LAG-3, high density of sTIL and high expression of LAG-3 are associated with better outcomes in patients with advanced gastric adenocarcinoma, respectively. Combined detecton of sTIL and LAG-3 may be more useful in gastric cancer than using either alone. Age, tumor size, Lauren classification and postoperative adjuvant chemotherapy are independent prognostic factors for patients with advanced gastric adenocarcinoma.

BACKGROUND:
Psoriasis is a chronic inflammatory skin disease, affecting about 0.6% of the Chinese population. Many patients are not well controlled by conventional treatments, thus there is need for new treatment regimens. In this study, we assessed the efficacy and safety of secukinumab in Chinese patients with moderate to severe plaque psoriasis.
METHODS:
This study was a 52-week, multicentre, randomized, double-blind, placebo-controlled, parallel-group, Phase 3 trial. A sub-population of study participants (≥18 years) of Chinese ethnicity were randomized to receive subcutaneous injections of 300 or 150 mg secukinumab, or placebo. The co-primary endpoints were psoriasis area severity index (PASI) 75 and Investigator's Global Assessment (IGA) 0/1 at Week 12.
RESULTS:
A total of 441 Chinese patients were enrolled in this study. Co-primary outcomes were achieved; 300 and 150 mg secukinumab were superior to placebo as shown in the proportion of patients that achieved PASI 75 (97.7% and 87.2% vs. 3.7%, respectively; P < 0.001), and IGA 0/1 (82.3% and 69.7% vs. 2.7%; P < 0.001) at Week 12. Treatment efficacy was maintained until Week 52. There was no increase in overall adverse events with secukinumab relative to placebo throughout the 52-week period.
CONCLUSION:
Secukinumab is highly effective and well tolerated in Chinese patients with moderate to severe plaque psoriasis.

DNA barcode technology was used to establish a rapid identification method of Chrysanthemum indicum and Ch. morifolium based on psbA-trn H,mat K and trn L sequences. The total DNA was extracted from 21 samples collected,and the psbA-trn H,mat K,trn L sequences were amplified by PCR and sequenced. The information of these sequences were obtained. We aligned all 63 sequences,calculated the intraspecific and interspecific distances,analysed the SNPs distribution of psbA-trn H+mat K+trn L combination sequences and constructed the Neighbor-joining( NJ) Tree,using MEGA 7. 0. The results showed that the genetic distances of Ch. indicum,Ch. indicum( Juhuanao)and Ch. morifolium were overlapped. The SNPs analysis of psbA-trn H+mat K+trn L combination sequences showed that there were 19 nucleotide polymorphism loci( SNPs) and nine parsim-informative sites in the combination sequences. In addition,Ch. indicum showed more obvious sequence polymorphism than those of Ch. indicum( Juhuanao) and Ch. morifolium. The psbA-trn H sequences showed obvious length variation.The NJ Tree showed that Ch. morifolium numbered C2-C5 were clustered into a single subbranch with a bootstrap value of 62%,and Ch.morifolium could be distinguished from Ch. indicum and Ch. indicum( Juhuanao). Moreover,Ch. indicum numbered Z9 and Z10 collected from Gansu province were singly clustered into one branch with a bootstrap value of 77%. It was also found that the changes of psbA-trn H and trn L sequences information of Ch. indicum samples from the northwest were obviously related to the geography and environment. Moreover,Ch.indicum and Ch. indicum( Juhuanao) had obvious differentiation,were also regarded as the evolutionary sources of Ch. morifolium. Therefore,psbA-trn H+mat K+trn L combination sequences as DNA barcode can identify Ch. indicum and Ch. morifolium accurately and rapidly,which provides an important basis for germplasm resources identification and species identification.

DNA barcode technology was used to establish a rapid identification method of Chrysanthemum indicum based on ITS2 sequences. The total DNA was extracted from 22 collected samples,and the ITS2 sequence was amplified by PCR and sequenced,and the information of ITS2 sequence was obtained. Another 14 items of the same family or the same genus were downloaded from Gen Bank.We aligned all 36 sequences,calculated the intraspecific and interspecific distances,and constructed Neighbor Joining( NJ) phylogenetic tree,using MEGA 7. 0. The difference of the secondary structure between the ITS2 sequences was compared. The results showed that the genetic distance of Ch. indicum and Ch. morifolium was overlapped,but the maximum intraspecific distance was far less than the minimum interspecific distance between and among Ch. indicum and other species,with an obvious barcoding gap. The NJ tree showed that Ch. indicum and Ch. morifolium shared a clade,and most of Ch. morifolium with some Ch. indicum were shared a subclade,while Inula lineariifolia,Sinosenecio oldhamianus and Senecio scandens belonged to one clade separately. ITS2 secondary structures for I. lineariifolia,S. oldhamianus and S. scandens were significantly different enough to identify completely but Ch. indicum and Ch. morifolium shared two secondary structures of A and B. It was proved that Ch. indicum was one of the evolutionary sources of Ch.morifolium. Therefore ITS2 sequence as DNA barcode can identify Ch. indicum and its adulterants accurately and quickly. The study provides an important basis for Ch. indicum for the identification of germplasm resources and the safety of clinical medication.

OBJECTIVE: To investigate the relationship of Ureaplasma urealyticum(UU)and Chlamydia trachomatis(CT)infections with reproductive tract microenvironment changes and clinical infertility.METHODS: From July 2018 to May2019,85 cases of tubal infertility were collected as the infertility group from the Outpatient Department of Reproductive Medicine Center,the Seventh Affiliated Hospital of Sun Yat-sen University.The ultrasonography and hysterosalpingography(HSG)showed normal size and shape of uterine cavity,and complete or incomplete obstruction of one or both fallopian tubes;infertility caused by other factors was excluded. The control group consisted of 45 normal women during the same period who had no previous pregnancy history and HSG showed no obvious abnormal fallopian tube. Vaginal and cervical secretions were collected to detect vaginal cleanliness and UU and CT infection.RESULTS: The vaginal cleanliness(Ⅲ-Ⅳ)of infertility group(18.82%)was more than that of control group(4.4%)(P<0.05).CT(18.82%),U(38.82%),CT+UU(15.29%)and total infection rates(72.94%)in infertility group were higher than those in control group(4.44%,8.89%,2.22% and 15.56%). The difference was statistically significant(P<0.01). Multivariate logistic regression analysis showed that tubal infertility was closely related to CT,UU and CT+UU infection(CT:P=0.046,OR=3.291;UU:P=0.025,OR=2.789;CT+UU:P=0.017,OR=7.528).CONCLUSION: CT and UU infections are strongly associated with tubal infertility. It is necessary to screen all women at childbearing age,especially infertile women,in order to clarify the relationship between these pathogens and impaired fertility and adverse pregnancy outcomes.
