Objective:To investigate the application value of laparoscopic-assisted total liver transplantation.Methods:The retrospective and descriptive study was conducted. The clinical data of 9 pairs of donors and recipients who underwent laparoscopic-assisted total liver transplanta-tion in People′s Hospital of Guangxi Zhuang Autonomous Region from January to April 2024 were collected. Of the donors, there were 8 males and 1 female, aged (39±18)years and with body mass index (BMI) of (20±4)kg/m 2. Of the recipients, there were 7 males and 2 females, aged (41±13)years and with BMI of (24±4)kg/m 2. Measurement data with normal distribution were represented as Mean± SD. Count data were described as absolute numbers. Results:(1) Surgical conditions. Of the 9 recipients, 7 recipients underwent laparoscopic-assisted total liver transplantation successfully, 1 recipient with severe portal hypertension converted to open surgery with reverse L-shaped incision due to the hemorrhage during the dissection of the first hepatic portal after completing liver mobilization under laparoscopy, and 1 recipient underwent trans-umbilical extension incision through the middle of the epigastric region due to the limited space for operation in the implantation of the donor liver. The total operation time for 7 recipients who successfully underwent laparoscopic-assisted total liver transplantation was (648±31)minutes, with a time of anhepatic phase of (57±5)minutes, the volume of intraoperative blood loss of (1 322±627)mL, the donor liver mass of (1 195±232)g, and the ratio of donor liver mass to recipient body mass of 1.86%±0.42%. The operation time for laparoscopic liver dissection and porta hepatis dissection in 8 recipients during surgery was (212±35)minutes. (2) Postoperative conditions. All 9 recipients recovered smoothly after surgery, without any vascular or biliary related complications, and the surgical incision recovered well. The duration of postoperative hospital stay of 7 recipients who successfully underwent laparoscopic-assisted total liver transplantation was (14.2±2.0)days. (3) Follow-up. All 9 recipients were followed up for 3 months after surgery. During the follow-up period, there was no vascular or bile duct related complication.Conclusion:Laparoscopic-assisted total liver transplantation can be applied to recipients who meet surgical conditions and achieve good short-term clinical efficacy.

Objective:To investigate the knowledge, attitudes, and practices (KAP) of pulse oximetry among pediatric healthcare providers in China and analyze the factor influencing the KAP.Methods:A self-developed questionnaire was used for an online research on the KAP of 11 849 pediatric healthcare providers from 31 provinces, autonomous regions, and municipalities of China from March 11 to 14, 2022.The factors influencing the KAP of pulse oximetry among pediatric healthcare providers were examined by Logistic regression. Results:The scores of KAP, of pulse oximetry were 5.57±0.96, 11.24±1.25 and 11.19±4.54, respectively.The corresponding scoring rates were 69.61%, 74.95%, and 55.99%, respectively. Logistic regression results showed that the gender and working years of pediatric healthcare providers, the region they were located, and whether their medical institution was equipped with pulse oximeters were the main factors affecting the knowledge score (all P<0.05). Main factors influencing the attitude score of pediatric healthcare providers included their knowledge score, gender, educational background, working years, region, medical institution level, and whether the medical institution was equipped with pulse oximeters (all P<0.05). For the practice score, the main influencing factors were the knowledge score, gender, age, and whether the medi-cal institution was equipped with pulse oximeters (all P<0.05). Conclusions:Chinese pediatric healthcare providers need to further improve their knowledge about and attitudes towards pulse oximetry.Pulse oximeters are evidently under-used.It is urgent to formulate policies or guidelines, strengthen education and training, improve knowledge and attitudes, equip more institutions with pulse oximeters, and popularize their application in medical institutions.

Objective: To investigate the sonographic features of primary thyroid lymphoma (PTL) and to evaluate the clinical significance of ultrasound-guided core needle biopsy (US-CNB) in PTL. Methods: A total of 24 patients with suspected PTL in Sir Run Run Shaw Hospital from January 2013 to June 2018 were analyzed retrospectively. All cases were confirmed by pathology, of them 23 patients received US-CNB and 1 patient chose operation without US-CNB, including 5 males and 19 females, aged from 39 to 75 years old. The effectiveness and safety of 23 patients with US-CNB were evaluated, and the sonographic features of 20 patients with PTL diagnosed by pathology were analyzed. Descriptive statistical methods were used in the study. Results: In the 23 patients with suspected PTL underwent US-CNB, 18 patients were diagnosed as PTL, 4 patients were respectively diagnosed as subacute thyroiditis, anaplastic carcinoma, Hashimoto's thyroiditis, and fibro thyroiditis, and the another patient was hard to diagnose by US-CNB and then was diagnosed as PTL by surgical biopsy. The success rate of US-CNB for diagnosis of PTL was 18/19, and no severe complications occurred in the patients with US-CNB. The other case was diagnosed as PTL by surgical biopsy without US-CNB. Sonographic features of 20 cases with PTL (18 cases diagnosed by US-CNB and 2 cases by surgery or surgery biopsy) were as follows: (1) Most nodules had irregular shapes and unsmooth margins; (2) Hypoechoic or markedly hypoechoic nodules with honeycombed or cord structures were observed in most cases; (3) Calcification was rare; (4) Multiple lesions were common; (5) Abundant intralesional vascularization was commonly observed; (6) Most cases had intensification of posterior acoustic enhancement; (7) Thyroid gland enlargement or with irregular shape; and (8) PTL often accompanied with lymph nodes enlargement in lateral neck or central region. Conclusion: PTL has certain sonographic features, with assistance of US-CNB, more accurate diagnosis of PTL can be obtained.

OBJECTIVE: To investigate the clinical manifestations pathologic features, treatment options and prognosis of patients with bone lymphoma. METHODS: The clinical characteristics, pathologic features, treatment and prognosis of 34 BL patients diagnosed by histopathologic method or/and PET-CT and treated in first hospital of peking university from January 2004 to April 2018 were analyzed retrospectively. RESULTS: The median age of 34 BL patients was 56 years old, the male and female ratio was 1.43∶1 (24 /10). Among 34 patients, the patients with primary bone lymphoma(PBL) were 8 cases, the patients with secondary bone lymphoma(SBL) was 26 cases, the PBL and SBL ratio was 0.31∶1. Bone lymphoma lacks typical systemic symptoms, and its onset began mostly from bone pain and pathologic bone fracture. The most frequent pathological type of bone lymphoma in our study was diffuse large B-cell lymphoma (DLBCL), accounting for 55.88%. At present, the conventional treatment for bone lymphoma includes chemotherapy, or chemotherapy combined with radiotherapy and surgery, as well as hematopoietic stem cell transplantation. The average and median OS time of BL patients were 349 years and 3 years respectively, meanwhile the OS rate for three years and two years were 56.25% and 78.16%, respectively. Factors that affect survival of BL patients were PBL and SBL classification, pathological type, blood LDH level, and treatment methods. CONCLUSION Bone lymphoma is usually concealed onset，an adequate and adequate combination therapy can improve the survival rate and transplantation therapy plays an important role. Primary bone lymphoma is rare, the prognosis of patients with primary bone lymphoma is good, whereas the prognosis of patients with secondary bone lymphoma is poor.

Objective To investigate the clinical data, risk factors for bleeding following endoscopic treatment of colorectal polyps (diameter ≥ 1.0 cm) and feature analysis for carcinogenesis of adenomatous polyps. Method It was analyzed retrospectively that the clinical data, endoscopic characteristics, risk factors for bleeding and features for carcinogenesis of adenomatous polyps in 741 patients with a total of 884 colorectal polyps (diameter ≥ 1.0 cm) of our hospital from January 1, 2014 to January 1, 2016, which were resected under endoscope. Result Univariate analysis of colorectal polyps resected under endoscope on intraoperative and delayed bleeding, we found that gender (P = 0.017), location (P = 0.011), size (P = 0.004), lobulated or not (P = 0.010), resection methods under endoscope (P = 0.029) were statistically significant deviation between the two groups; taking the polyp as observation unit,multivariate Logistic regression analysis of their clinical data and endoscopic characteristics, we found gender (P = 0.012, OR^ = 2.671, 95% CI = 1.246 ~ 5.728) was an independent risk factor, men are more prone to bleeding than women; it was a protective factor for the location of polyps is sigmoid colon compared to rectum (P = 0.011, OR^ = 0.348, 95% CI = 0.154 ~ 0.786), and it was a risk factor for the polyps whose diameters ≥ 3.0 cm compared to among 1.0 ~ 1.9 cm. Univariate analysis of the features for carcinogenesis of colorectal adenomatous polyps, we found that surface lobulated or not (P = 0.001), surface smooth or not (P = 0.017), Yamada classification (P = 0.008) were statistically significant deviation, and the logistic regression analysis identified surface lobulation (P = 0.001, OR^ = 6.556, 95% CI = 2.326 ~ 18.475) was an independent risk factor for carcinogenesis of adenomatous polyps. Conclusion Resection of colorectal polyps under endoscope is a safe treatment method. Taking the polyp as observation unit, gender is an independent risk factor of colorectal polyps resected under endoscope on intraoperative and delayed bleeding, men are more prone to bleeding than women; the larger the diameters of polyps are, the higher the bleeding rates could be. Surface lobulation of colorectal adenomatous polyps are more likely lead to carcinogenesis.

BACKGROUNDAtopic dermatitis (AD) is an inflammatory skin disease characterized by chronic recurrent dermatitis with profound itching. Most patients have personal and/or family history of atopic diseases. Several criteria have been proposed for the diagnosis of AD. Although the clinical features of childhood AD have been widely studied, there has been less large-scale study on adult/adolescent AD. The aim of this study was to investigate the clinical features of adult/adolescent patients with chronic symmetrical eczema/AD and to propose Chinese diagnostic criteria for adult/adolescent AD.

METHODSA hospital-based study was performed. Forty-two dermatological centers participated in this study. Adult and adolescent patients (12 years and over) with chronic symmetrical eczema or AD were included in this study. Questionnaires were completed by both patients and investigators. The valid questionnaires were analyzed using EpiData 3.1 and SPSS 17.0 software.

RESULTSA total of 2662 valid questionnaires were collected (1369 male and 1293 female). Of all 2662 patients, 2062 (77.5%) patients had the disease after 12 years old, while only 600 (22.5%) patients had the disease before 12 years old, suggesting late-onset eczema/AD is common. Two thousand one hundred and thirty-nine (80.4%) patients had the disease for more than 6 months. One thousand one hundred and forty-four (43.0%) patients had a personal and/or family history of atopic diseases. One thousand five hundred and forty-eight (58.2%) patients had an elevated total serum IgE and/or eosinophilia and/or positive allergen-specific IgE. Based on these clinical and laboratory features, we proposed Chinese criteria for adult/adolescent AD. Of all 2662 patients, 60.3% were satisfied with our criteria, while only 48.2% satisfied with Hanifin Rajka criteria and 32.7% satisfied with Williams criteria, suggesting a good sensitivity of our criteria in adult/adolescent AD patients.

CONCLUSIONLate-onset of eczema or AD is common. The clinical manifestations of AD are heterogeneous. We have proposed Chinese diagnostic criteria for adolescent and adult AD, which are simple and sensitive for diagnosis of adult/adolescent AD.

OBJECTIVEThe aim of the present study was to screen the Metarhizium strains with high virulence against the larvae of Dorysthenes hydropicus, a serious pest of Citrus grandis.

METHODThirty six strains of Metarhiziums were isolated from the soil of C. grandis GAP base and collected from other institutions, and the pathogenicity of these strains against 1st instar larvae of D. hydropicus was detected at concentration of 1 x 10(8) conidia/g. The high violence strains against D. hydropicus were cultivated in sabouraud dextrose yeast medium at first, then transfer to rice grain. And the sporulations of these violent strains against D. hydropicus were detected.

RESULTTwenty-eight strains showed virulence against D. hydropicus by preliminary study, and 7 strains of them were collected for further study, 6 of the 7 showed high virulence, the highest cadaver rate was higher than 74%. The conidia production of strain 1 and strain 4 were 2.35 +/- 0. 25 (1 x 10(9) conidia/g), 2.21 +/- 0.27 (1 x 10(9) conidia/g), respectively, showed significantly higher than other strains.

CONCLUSIONStrain 1 and strain 4 of the 36 Metarhiziums strains showed high virulence against D. hydropicus, and the highest sporulation ability, so they have a best application prospect.

OBJECTIVETo evaluate the efficacy and safety of weekly paclitaxel combined with S-1 or fluorouracil in the first line treatment of advanced gastric carcinoma.

METHODSTwo hundred and forty patients with untreated advanced gastric carcinoma were randomized into two arms, patients in the experimental arm were given paclitaxel and S-1, while those in the control arm received paclitaxel and fluorouracil. The regimen of experimental arm was paclitaxel 60 mg/m(2) by intravenous infusion, day 1, 8, 15; S-1 80 - 120 mg/day given by oral administration, day 1 - 14. The regimen of control arm was fluorouracil 500 mg/m(2) by intravenous infusion continuously, day 1 - 5; CF 20 mg/m(2) by intravenous infusion, day 1 - 5. The regimens in both arms were repeated every 28 days. The efficacy and safety of both arms were assessed.

RESULTSTwo hundred and twenty-eight patients were analyzed in the full analysis set, and 192 patients were analyzed in per-protocol set (experimental arm 100 patients, control arm 92 patients). The overall response rates of experimental and control arms were 50.0% and 28.3% (P = 0.002), and the disease control rates were 82.0% and 70.7% (P = 0.064), respectively. The primary endpoints of experimental arm were non-inferior to that of the control arm. The secondary endpoint of experimental arm in terms of median progression free survival was significantly better than that of control arm (5 months versus 4 months, P = 0.006). The experimental arm had a higher incidence of grade III-IV bone marrow suppression than the control arm, but the incidence of fever in both arms was not significantly different.

CONCLUSIONSOral administration of S-1 is an alternative option of venous infusional fluorouracil. Weekly paclitaxel combined with S-1 is a safe regimen and has a promising efficacy.
