OBJECTIVETo compare the efficacy of two surgical techniques for controllong nasal width after Le Fort I osteotomy.

METHODSFifty-five patients who received the Le Fort I osteotomy have been included in this study. They were randomly divided into 2 groups. The experimental group received extraoral ABS, and the control group received traditional intraoral ABS. 3D photos of the patient's face were taken before operation and at postoperative 3 months. Alar width was measured on the 3D photos. Data was reported as means and standard deviations, and statistic analysis was done by using student t test.

RESULTSCompared with presurgical data, G. lat-G. lat increased by (2.66 +/- 1.47) mm, Al-Al increased by (2.20 +/- 1.22) mm and Sbal-Sbal increased by (1.30 +/- 1.33) mm in experimental group. G. lat-G. lat increased by (1.38 +/- 1.29) mm, Al-Al increased by (1.06 +/- 0.95) mm and Sbal-Sbal increased by (0.36 +/- 1.33) mm in the control group. There was significant difference between two groups.

CONCLUSIONSThe surgical technique of ABS is the most important factor for determining the postoperative alar width. Both techniques have better effect on the Sbal-Sbal width control than the G. lat-G. lat and Al-Al width control. Traditional intraoral ABS can more effectively control the alar width. Both techniques cannot completely control the alar base widening after Le Fort I osteotomy.

OBJECTIVETo explore the effects of rearing patterns on diet and temperament traits among infants in urban areas.

METHODSA total of 480 25-30-month-old infants were randomly selected from the birth cohort in Hefei Maternal and Child Health Care Center in 2008. A household survey was conducted using China Toddler Temperament Scale (CTTS), Dietary Characteristics Questionnaire and Family Environment Questionnaire.

RESULTSOf the 430 surveyed households, there were three main rearing patterns including parents rearing pattern (Group A), grandparents rearing pattern (Group B) and joint rearing pattern (Group C), accounting for 33.0%, 21.2% and 45.8%, respectively. Infants in Group A tended to adopt processed food pattern, with poor rhythmicity and adaptability; infants in Group B tended to adopt fruit, vegetable, and cereals-based food pattern, with relatively poor rhythmicity; infants in Group C tended to adopt aquatic products and fruit/vegetable-based food pattern, with good rhythmicity and adaptability. Linear regression model showed that infants who consumed more aquatic products, high-protein food, and fruits/vegetables had more positive temperamental traits, whereas infants who consumed more processed foods had more negative temperamental traits.

CONCLUSIONSA joint rearing pattern may be a favorable rearing style for infants aged 25-30 months in urban areas in terms of diet and temperament traits.

OBJECTIVETo evaluate the impacts of maternal weight gain during pregnancy on offspring weight and obesity from birth to 24 months of age.

METHODSThe information on maternal pre-pregnancy body mass index (BMI), gestational weight gain and demographic characteristics were collected from 317 pregnant women. The information on offspring weight, BMI and breastfeeding data was obtained from various follow-up examinations from 0 to 24 months of age.

RESULTSThe logistic regression analysis showed that excessive gestational weight gain resulted in an increased risk of obesity in children at age of 6 months (adjusted RR=3.56, 95% CI:1.31-8.35) and 9 months (adjusted RR=2.87, 95% CI: 1.04-3.28) after adjustment for potential confounding factors. The linear regression model showed that there were significant correlations between gestational weight gain and Z score of weight in offsprings at birth (β=0.032, 95% CI: 0.008-0.057), 3 months (β=0.037, 95% CI: 0.013-0.062), 6 months (β=0.043, 95% CI: 0.017-0.068), 9 months (β=0.038, 95% CI: 0.013-0.063) and 12 months (β=0.034, 95% CI: 0.009-0.059), but not at 18 months and 24 months.

CONCLUSIONSExcessive gestational weight gain may affect offspring weight and increase the risk of obesity in children from birth to 12 months of age. During their second year of life, this effect will temporarily disappear.

OBJECTIVETo analyze virulence genes and molecular characteristics of Vibrio parahaemolyticus isolated from sporadic cases with diarrhea in tow sentinel hospitals of Shanghai, 2010-2012.

METHODSA total of 2 729 stool samples were collected from two surveillance sentinel hospitals in Shanghai 2010-2012. Vibrio parahaemolyticus strains were isolated and identified from diarrhea out patients using TCBS agar plates and biochemical reactions. Thermostable direct hemolysingene (tdh), thermostable-related hemolysin gene (trh), hemolysin gene (tlh) were detected by multiplex PCR method. Isolates were analyzed by PFGE and MLST. The PFGE profiles were analyzed using BioNumerics software.

RESULTSA total of 30 clinical Vibrio parahaemolyticus strains isolated from 2 729 stool samples. The anually Vibrio parahaemolyticus isolation rate during 2010 to 2012 were 1.1%(11/973), 1.0%(11/1 120) and 1.3%(8/636) respectively. The PCR positive rates of virulence genes tlh, tdh and trh were 100%, 97% and 0 respectively. The Vibrio parahaemolyticus strains were divided into 13 PFGE types (P1-P13)and 3 ST types (ST-189, ST-799, ST-3). Among 13 PFGE types, P4 was the main PFGE type, accounting for 30%(9/30). P9, P10 were accounting for 12% (4/30) respectively, P1, P2, P12, P13 were accounting for 7%(2/30) respectively, the others types were 3%(1/30) respectively. MLST analysis results showed there are three ST types, ST3 was 84%(25/30), ST189 and ST799 were accounting for 13% (4/30) and 3% (1/30) respectively.

CONCLUSIONThe infection rate of Vibrio parahaemolyticus was not very high from 2010-2012 in Shanghai, all strains were positive for tlh and negative for trh. ST3 was the major type of Vibrio parahaemolyticus.

A new compound(Z)-6-hydroxy-4-methoxy-5,7-dimethylaurone was isolated from Cleistocalyx operculatus flower buds. Its structure was identified by spectroscopic data including MS, ¹H-NMR, ¹³C-NMR HSQC and HMBC. A known compound, 2',4'-dihydroxy-6'-methoxy-3'5'-dimethylchalcone (DMC), was also isolated and identified,and used as material to synthesize (Z)-6-hydroxy-4-methoxy-5,7-dimethylaurone.Anti-inflammatory activities of the two compounds were tested . The results showed that (Z)-6-hydroxy-4-methoxy-5,7-dimethylaurone possesses much stronger PGE₂ inhibitory activity (IC₅₀ 6.12 nmol·L⁻¹) than the positive control ibuprofen （68.66 nmol·L⁻¹）.

OBJECTIVETo study the prevalence of severe acute respiratory syndrome coronavirus (SARS-CoV) like virus in animals at a live animal market of Guanzhou in 2004 before and after culling of wild animal action taken by the local authority, in order to predict the re-emerging of SARS from animal originals in this region.

METHODSAnimals at live animal market were sampled for rectal and throat swabs in triplicate. A single step realtime reverse transcription-polymerase chain reaction (RT-PCR) diagnostic kit was performed for screening SARS-CoV like virus, the manual nested RT- PCR and DNA sequencing were performed for confirmation. Only specimens which tested positive for both of the N and P genes by nested RT-PCR were scored as positive.

RESULTSIn 31 animals sampled in January 5 2004 before culling of wild animals at Guangdong Province, including 20 cats (Felis catus), 5 red fox (Vulpes vulpes) and 6 Lesser rice field rats (Rattus losea), 8 (25.8%) animals were tested positive for SARS-CoV like virus by RT-PCR methods, of which 4 cats, 3 red fox and one Lesser rice field rats were included. However, two weeks after culling of animals and disinfection of the market were implemented, in 119 animals sampled in January 20 2004, including 6 rabbits (Oryctolagus cuniculus), 13 cats, 46 red jungle fowl (Gallus gallus), 13 spotbill duck (Anas platyrhynchos), 10 greylag goose (Anser anser), 31 Chinese francolin (Franclinus pintadeanus), only rectal swab from one greylag goose was tested positive for SARS-CoV like virus. Furthermore, in 102 animals that including 14 greylag gooses, 3 cats, 5 rabbits, 9 spotbill duck (Anaspoecilorhyncha), 2 Chinese francolin (Franclinus pintadeanus), 8 common pheasant (Phasianus colchicus), 6 pigeons, 9 Chinese muntjac (Muntiacus reevesi), 19 wild boar (Sus scrofa), 16 Lesser rice field rats, 5 dogs, 1 mink (Mustela vison), 3 goats, 2 green peafowl (Pavo muticus) sampled in April, May, June, July, August and November, only rectal swab from one pig was tested positive. However, of 12 and 10 palm civets sampled in November and December including five of which had been at the live animals market for 2 days, none of them was tested positive.

CONCLUSIONThis findings revealed that animals being sampled in April, May, June, July, August and November of 2004, only one rectal swab from a pig was tested positive as SARS-CoV like virus, much lower than the results from the previous year, suggesting that the possibility of re-emerging of human infection from animal origins is low for the winter of 2004-2005.

Japanese Society for Cancer of the Colon and Rectum (JSCCR) guideline 2019 recommended that lymph node dissection for advanced rectal cancer should include the lymphatic adipose tissue at the root of the inferior mesenteric vessels, but the ligation site of the inferior mesenteric artery (IMA) was not determined, and the NCCN guideline did not indicate clearly whether to retain the left colonic artery (LCA). Controversy over whether to retain LCA is no more than whether it can reduce the incidence of anastomotic complications or postoperative functional damage without affecting the patients' oncological outcome. Focusing on the above problems, this paper reviews the latest research progress. In conclusion, it is believed that the advantages of retaining LCA are supported by most studies, which can improve the blood supply of the proximal anastomosis, and technically can achieve the same range of lymph node dissection as IMA high ligation. However, whether it affects the survival of patients, reduces the incidence of anastomotic leakage, and improves the quality of life of patients, more high-quality evidence-based medical evidence is still needed.
