Objective To analyze the efficacy of repairing unilateral cleft lip (UCL) with Millard method, and explore the individual operative procedure. Methods According to the difference of lip height between non-cleft and cleft sides, MillardⅠ, MillardⅡ or modified Millard Ⅱ operative approach was chosen to repair UCL, then the clinical effect of operation was evaluated. Results The ideal operative effects were obtained in 208 cases of UCL using various operative approaches based on the individual deformity. There were consistent lip height between both sides, normal vermillion bulk and satisfactory facial appearance after operation. Conclusion The satisfactory efficacy could be obtained by choosing Millard method's operative approaches based on the individual deformity. The modified Millard operative approach could repair all kinds of UCL.

Objective To establish a new flow-injection chemiluminescence(CL) method for the determination of hydrocortisone.Methods In H2SO4 solution,hydrocortisone could obviously enhance the chemiluminescence intensity of the reaction of KMnO4-Na2SO3 system.Based on this,a new flow-injection CL method for the determination of hydrocortisone was developed.Results There was a good linear relationship between CL intensity and the concentration of hydrocortisone in the range of 1.0?10-9-1.0?10-6g/mL.The detection limit was 4.0?10-10g/mL at a signal-to-noise ratio of 3∶1.The RSD of 11 assays was 2.2%.Conclusion This method can be successfully used to determine the quantity of hydrocortisone in injection.It is rapid,accurate,simple,and has high sensitivity and wide linear range.

Objective To discuss the preventive measures of anterior palatal fistula by modified the operation of cleft palate. Methods For 23 patients of complete cleft palate with alveolar ridge cleft, bilateral mucoperiosteum flap was moved forward as possible so as to close fistula front of hard palate, and incised junction of the hard and soft palate to prolong soft palate and the wound was repaired by buccal mucosal flap.The incidence of anterior palatal fistula and velopharyngeal closure after operation was observed. Results Twenty-three patients were rechecked 1 month after operation ,there was no anterior palatal fistula occurring,10 cases were examined by epipharyngoscope 1 year after operation,the velopharyngeal closure was 90%-100%. Six cases were followed up for 6 months,the velopharyngeal closure was 80%-85%. Conclusions For second-stage operation methods of anterior palatal fistula, there are too many discussions of selection criterias, advantages and disadvantages. If first-stage operation is taken measures to prevent anterior palatal fistula or decrease the diameter of fistula as possible. It reduces percentage of second-stage operation or decreases the difficulty. It should get more attention in the clinical works.

Objective: To investigate the molecular typing and drug resistance of Salmonella in market-sold raw livestock meats in Shaoxing City, Zhejiang Province, so as to provide the basis for the prevention and control of drug-resistant Salmonella. Methods: Salmonella isolates were detected and serotyped from raw livestock meat samples collected from supermarkets, agricultural markets and restaurants in Shaoxing City between March and November 2023. Molecular typing was performed using pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST). Antibiotic resistance phenotypes and resistance gene analyses were conducted using broth microdilution method and whole genome sequencing. Results: A total of 34 Salmonella isolates were detected from 329 samples and the positive rate was 10.33%. There were 14 serotypes, with S. Rissen (9 isolates, 26.47%) and S. London (8 isolates, 23.53%) being dominant. PFGE typing revealed 31 band patterns and 23 banding pattern clusters of Salmonella, and the similarity ranged from 30.80% to 100.00%, without dominant band patterns. MLST identified 15 sequence typing (ST) types, and S. Rissen were all ST469 and S. London were all ST155. Salmonella strains exhibited high levels of resistance to tetracycline (44.12%) and ampicillin (35.29%). Thirteen resistance patterns were identified, with 8 multidrug resistant patterns (29.41%). There were 8 classes of 14 resistance genes, with aminoglycoside resistance gene aac(6' )-Iaa found in 100.00% of the strains. The highest concordance rate between the resistance phenotype and gene was observed for phenicol antibiotics (97.06%), while there was no concordance between the quinolone resistance phenotype and genes. Conclusions S. Rissen and S. London are the predominant serotypes in market-sold raw livestock meats in Shaoxing City. The PFGE band types of the Salmonella isolates show polymorphism distribution, and MLST are mainly ST469 and ST155. The isolates have high levels of resistance to tetracycline and ampicillin, manifesting multidrug resistance.

Objective To observe the pathological changes of tissues of the injured bile duct, and to provide theoretical basis for bile duct repair. Methods Dog models of obstructive biliary injury were established.Sixty dogs were equally divided into five groups according to the duration of biliary obstruction: biliary obstruction for 5 days (BDL5 group), 10 days (BDL10 group), 15 days (BDL15 group), 20 days (BDL20 group) and 30 days (BDL30 group). The morphological and pathological changes of bile duct and local tissues were observed, and biliary-enteric Roux-en-Y anastomosis was applied to repair the injured bile duct and postoperative complications were observed. All data were analyzed by LSD test, independent sample t test, one-way analysis of variance and chi-square test. Results Proximal bile duct rapidly expanded as the pressure increased in the early stage, and the bile duct expanded to ( 15.6 ± 1.8)mm in the BDL10 group. The expansion rate decreased in the later stage,and the bile duct expanded to (18.9 ± 1.9)mm in the B DL15 group. Acute inflammation was observed in injured local tissues. The acute inflammation was severe in the BDL5 group with white blood cell count of 54 ± 6, and the acute inflammation was relatively mild in the BDL15 group with white blood cell count of 42 ± 7. There was a significant difference between the BDL5 group and BDL15 group in the degree of acute inflammation (t =4. 688,P ＜ 0. 05). The content of the collagen was increased in the injured bile duct as time passed by. Bile duct repair was successfully performed on 57 dogs. Ten dogs ( three in the BDL5 group, four in the BDL10 group, one in the BDL15 group, one in the BDL20 group and one in the BDL30 group) died of bile leakage after the operation. The incidences of bile leakage was 30% (7/23) within 10 days and 9% (3/34) beyond 10 days, with a significant difference between the two groups (x2 =4.429, P＜0.05). Conclusion Ten days after obstructive biliary injury,an obvious reduction of bile duct expansion and edema of the bile duct is observed, the difficulty of the operation is reduced and the incidence of bile leakage is low, so 10 days after the incidence of obstructive biliary injury is the proper timing for the surgical repair.
