ObjectiveTo assess revascularization and vessel anastomosis in digital replantations with DSA.MethodsTwelve cases of digital replantations underwent digital subtract angiography during 2 to 4 days after fingers reattachment. The vessel anastomosis,hemodynamics,stenosis and discontinuation were investigated.The unobstructed and smooth anastomosis was suggested as early stage survival of the reattached fingers,the spasm and stenosis of the reattached vessels were considered as mild vascular crisis,and the discontinuation of hemodynamics were indicated as severe vascular crisis.ResultsThe total 27 vessels were clearly displayed on DSA.Of these vessels,23 vessels were unobstructed and smooth,all digits were survived.Diagnosis coincidence of early stage survival was 100%(23/23). Two vessels were obstructed,which were testified having thrombus by operation research.The other 2 vessels were spasm,the digits were also survived ultimately by expectant treatment.All 4 abnormal vessel anatomosis were found by DSA.Conclusion DSA is important modality in assessing revascularization and blood circulation for digital replantations,guiding in dealing with the vascular crisis,and in predicting early stage survival of the reattached digits.

BACKGROUND: The dramatic increase in use of the IgG test for toxoplasma, rubella, cytomegalovirus (CMV), and herpes simplex virus (HSV) [TORCH] has led to the requirement for a high-efficiency method that can be used in the clinical laboratory. This study aimed to compare the results of BGI-Array ELISA TORCH IgG (BGI-GBI, China) screening method to those of Virion/Serion TORCH IgG ELISA (Virion/Serion, Germany). METHODS: Serum specimens (n=400) submitted for routine IgG testing by Virion/Serion ELISA were also tested using the BGI-Array ELISA method. The agreements of these two kinds of method were analyzed by kappa-coefficients calculation. RESULTS: Following repeat testing, the BGI-Array ELISA TORCH IgG assays demonstrated agreements of 99.5% (398/400 specimens), 98% (392/400 specimens), 99% (396/400 specimens), and 99.5% (398/400 specimens), respectively. The BGI-Array ELISA IgG assays provided results comparable to Virion/Serion ELISA results, with kappa-coefficients showing near-perfect agreement for the HSV (kappa=0.87), rubella (kappa=0.92) and CMV (kappa=0.93) and substantial agreement for the toxoplasma (kappa=0.80) IgG assays. The use of the BGI-Array ELISA TORCH IgG assays could reduce the turnaround time (1.5 hr vs. 5 hr by Virion/Serion ELISA for 100 specimens) and were easy to use. CONCLUSIONS: BGI-Array ELISA TORCH IgG shows a good agreement with Virion/Serion ELISA methods and is suitable for clinical application.

Objective: To present a new method for correction of prominent malar complex via intraoral approach by double support technique osteotomy which can provide a stable support. Methods: According to the anatomical characteristics of malar complex and relevant masseter muscle, we designed a malar reduction technique including anterior and posterior support. The reduction procedure entailed an L-shaped osteotomy ofthemalarbody and oblique osteotomy of malar arch. On the basis of prominence degree, bone fragment was moved inward and upward to form double support, which could reduce malar and zygomatic arch effectively. Results: A total of 76 patients subjected to double support technique for malar reduction between January 2015 and January 2017 were retrospectively reviewed.The follow-up period ranged from 10 to 12 months. All patients were satisfied with aesthetic outcomes without major complications, such as facial nerve damage or bone ununion. Conclusions Double support technique is an effective method to correct malar prominence andreduce the zygomatic complex which can prevent saggy cheek and bony malunion.

Objective:To evaluate the quantitative diagnostic value of controlled attenuation parameter (CAP) in health checkup groups with asymptomatic nonalcoholic fatty liver disease.Methods:A multicenter prospective study was conducted among Chinese individuals undergoing regular health checkups; a total of 173 subjects were investigated. Human body indexes such as height, weight, and blood pressure were measured, and complete blood count, liver function, blood lipid, FibroScan, and MRI-PDFF examinations were performed. Correlation between MRI-PDFF and CAP was described using Spearman′s and Pearson′s coefficients. Diagnostic efficacy of the CAP was evaluated using the subject work characteristic curve and the area under this curve, and the optimal cut-off value was determined according to the Youden index.Results:The average age and body mass index of the subjects were 45.0±10.5 years and 25.8±4.0 kg/m 2, respectively. A linear correlation was found between CAP and lg transformed magnetic resonance imaging-based proton density fat fraction results (Pearson′s coefficient 0.772, P<0.001). When optimized for ≥90% sensitivity, the CAP cutoff for staging ≥S1 steatosis was 244 dB/m. Conclusions:The CAP result was significantly correlated with the liver fat fraction measured by MRI-PDFF, and capable of differentiating steatosis grades. CAP can be used as a tool for screening fatty liver in health checkup groups.

Objective To discuss the correlation between initial malar reduction procedures and the method of revision procedures and the personalized treatment strategies for the second deformity of postoperative prominent malar complex.Methods From January 2003 to December 2017,27 patients underwent personalized revision surgery of malar reduction according to the different second deformity of malar complex.The surgical technique included the double support malar reduction technique,orthotopic malar osteotomy technique,malar bone grinding surgery,and autogenous bone transplantation.Results A total of 27 patients subjected to revision surgery for malar reduction between November 2006 and December 2017 were retrospectively reviewed.22 patients were satisfied with aesthetic outcomes after the first revision procedure,while 5 patients were satisfied after 2 or 3 procedures follow-up for 10 to 12 months.Conclusions The incidence of complications after malar reduction is related to the first surgical method.According to the unsatisfactory results,it can be repaired individually to obtain a better clinical repair effect.

Objective:To study the genetic profile of neonatal hyperbilirubinemia with unknown etiology in Guangdong Province and the clinical significance of jaundice-related genetic screening.Methods:From July to September, 2021, neonates with hyperbilirubinemia of unknown etiology born in different hospitals in Guangdong Province were studied. 24 neonatal jaundice-related exons were sequenced using targeted capture and high-throughput sequencing technology. The pathogenic variants were analyzed.Results:A total of 331 cases, 139 (42.0%) cases showed positive screening results with five diseases, including 65 (19.6%) cases of Gilbert syndrome, 48 (14.5%) cases of glucose-6-phosphate dehydrogenase (G6PD) deficiency,18 (5.4%) cases of sodium taurocholate cotransporting polypeptide deficiency, 4 (1.2%) cases of Citrin deficiency and 4 (1.2%) cases of Dubin-Johnson syndrome. 149 (45.0%) cases carried one or more genetic variants and 43 (13.0%) cases showed no clinically significant variants. The 8 high-frequency mutation loci (carrier rate >1%) are UGT1A1 gene c.211G>A and c.1091C>T, G6PD gene c.1466G>T and c.1478G>A, SLC10A1 gene c.800C>T, SLC25A13 gene c.852_855del TATG, HBB gene c.126_129delCTTT and c.316-197C>T.Conclusions:Genetic factors are important for neonatal hyperbilirubinemia with unknown etiology in Guangdong. The common pathogenic genes are UGT1A1, G6PD, SLC10A1, and SLC25A13 and the population carries high-frequency mutation loci. Therefore, genetic screening in neonates with hyperbilirubinemia of unknown etiology has important clinical significance.

Objective:To introduce and validate the Pediatric Nausea Assessment Tool (PeNAT) and the Baxter Retching Faces Scale (BARF) in the assessment of chemotherapy induced nausea in Chinese children with malignant neoplasms, and to explore the cut-off value for rescue antiemetic.Methods:A prospective descriptive study was conducted, 244 children in Sun Yat-sen University Cancer Center with malignant neoplasms who received chemotherapy were selected by convenience sampling from July to August 2021. PeNAT, BARF, Visual Analogue Scale (VAS) and the Faces Pain Scale-Revised(FPS-R) were used to assess the severity of nausea and pain before and after chemotherapy, before and 30-60 minutes after the use of rescue antiemetic or analgesic. After chemotherapy, the children also were asked the changes of nausea severity and whether antiemetic was needed.Results:A test-retest reliability was conducted on the patients with the same severity of nausea before and after chemotherapy, and the intraclass correlation coefficient of the PeNAT and BARF were 0.940 (both P<0.05). After chemotherapy, the PeNAT and BARF were 1.5(1.0, 2.0) and 2.0(0, 2.0) points, which were significantly higher than the 1.0(1.0, 1.0) and 0(0, 0) points before chemotherapy ( Z = - 9.19, - 9.09, both P<0.01). The PeNAT and BARF of 11 cases receiving antiemetic before medication were 4.0 (4.0, 6.0) and 3.0(2.0, 4.0) points, which were higher than the 0(0, 2.0) and 1.0(1.0, 2.0) points without antiemetic ( Z = - 4.03, - 3.86, both P<0.05). After chemotherapy, the correlation coefficients between PeNAT or BARF and VAS-nausea were r = 0.933, 0.957 (both P<0.01), and FPS-R were r = 0.192, 0.189 (both P<0.05). After using antiemetic, PeNAT and BARF were 2.0(2.0, 3.0) and 2.5(2.0, 4.0) points, which were significant different than the 3.0(3.0, 3.8) and 4.0(4.0, 8.0) points before using antiemetic ( Z = - 2.97, - 2.83, both P<0.05). According ROC curves and cut-off values, it was determined that PeNAT≥3 and BARF≥4 had clinical significance and require clinical intervention. Conclusions:PeNAT and BARF have excellent reliability and validity in the assessment of chemotherapy induced nausea in children with malignant neoplasms, they can effectively identify the requirement of rescue antiemetic, and evaluate the efficacy of antiemetic.

OBJECTIVETo analyze the cost effectiveness of HIV screening project in three Guangxi infectious disease special demonstration project countries in 2013.

METHODSTo calculate the funds used for the HIV screening project and to study the data on HIV/AIDS and HAART. A five-tree markov model was used to evaluate the quality adjusted life year (QALY) of this HIV screening project and to analyze the related cost effectiveness of the project.

RESULTSThe cost of HIV screening in Guangxi infectious disease special demonstration project areas was 19.205 million Yuan and having identified 1 218 HIV/AIDS patients. The average costs for HIV/AIDS positive detection in three project countries were 14.562, 18.424 and 14.042 thousand Yuan per case. The QALYs gained from finding a HIV/AIDS case were 12.736, 8.523 and 8.321 on average, with the total number of QALYs gained from the project as 5 973.184, 3 613.752 and 2 704.325. The overall cost effectiveness ratio of the project was 1.562 thousand Yuan per QALY, and 1.143, 2.162 and 1.688 thousand Yuan per QALY in these three project countries. Project country "A" showed better cost effectiveness index than country B and C.

CONCLUSIONThe HIV screening project in Guangxi seemed relatively cost-effective but the average cost of HIV/AIDS positive detection was expensive. To strengthen HAART work for HIV/AIDS could improve the cost-effective of the project.

OBJECTIVETo understand the illegal sidenafil use among middle-aged and elderly male clients of female sex workers (FSWs) in central region of Guangxi as well as on related risk factors. Initial evaluation regarding the effect of illegal sidenafil use on HIV infection among the middle-aged and elderly men was also conducted.

METHODSA survey was conducted among the over 50-year-olds male clients of low-grade prostitutions in central areas of Guangxi. Information on demographics, related behavior, and illegal sidenafil use was collected. 5 ml blood sample were taken to test antibodies of HIV and syphilis. PASW Statistics 18.0 was used for data analysis.

RESULTS2 056 questionnaires were completed. 23.1% of the participants said they had ever used illegal sidenafil. The risk of sildenafil use was low among the male clients who were not over 60 years old (OR = 0.586, 95% CI:0.459-0.749). The risks of sildenafil use among the male clients with frequencies(in the past 30 days) of having commercial sex behavior were:only once (OR = 0.184, 95%CI:0.090- 0.378), twice (OR = 0.187, 95%CI:0.089-0.378) or three times (OR = 0.181, 95%CI: 0.085-0.384) lower than those with more than five times. Being single (OR = 0.608, 95% CI: 0.396-0.933), married/cohabiting (OR = 0.533, 95% CI:0.391-0.727), having unstable partners (OR = 0.558, 95%CI:0.393-0.792) seemed to be protective on those who used sildenafil, among the study population. Factors as 'never use the condom (OR = 1.642, 95%CI:1.125-2.397) or 'seldom use as condom (OR = 1.840, 95%CI:1.278-2.648) when having commercial sex, were under high risk among the sildenafil users. Forty-seven subjects were HIV positive, with the prevalence as 2.29% in this study population. Male clients of the FSWs who used sidenafil were under 60 years of age and with higher risk of HIV infection.

CONCLUSIONpeople who were ≥60 years old, divorced/widowed/ separated, with frequencies (in the past 30 days) of having commercial sex more than 5 times, never or occasionally using a condom when having commercial sex etc., appeared at high risk. Middle-aged and elderly male clients who used sildenafil or sildenafil-like drugs were under high risk of contracting HIV infection.
