Objective To investigate the status of food hygiene safety in troop catering units, analyze the major problems, and to improve the service system of food safety in troops.Methods Seventy troop catering units were investigated by means of cross-sectional questionnaire surveys, on-site inspections and rapid detection methods.Results Among the 70 troop catering units, 70.0%were self-managed,and 28.6%were run by civilians.From them, 64.3%of these units were centralized above the regimental level.Five main problems with food safety were found during food processing:uncomplete cleaning and disinfection of the tableware, irrational layout of processing rooms, co-contamination in the processing link, purchase and storage problems of raw materials, and sub-standard internal management of hygiene.44.3%of the catering units had inspection staff, 40.0% were equipped with inspection equipment, and 35.7% had food inspection rooms. Conclusion There are potential hazards to food safety in troop catering units.The implementation of hygienic regulations should be strengthened, and food safety related equipment improved.In addition, staff′s awareness of hygiene should be enhanced, internal supervision should be strengthened, and the mechanism of rewards and punishments should be established.

Objective To analyse the changes in bilateral optic radiation and visual cortex in patients with primary glaucoma detected by magnetization transfer imaging ( MTI ),and try to explore the influence of the disease on posterior visual pathway.Methods MTI was performed in 20 patients with primary glaucoma with normal signal on conventional magnetic resonance imaging (MRI).The same scanning was performed in 31matched healthy controls.MTI was obtained using spoiled gradient recalled acquisition sequence (SPGR).Magnetization transfer ratio ( MTR ) of bilateral optic radiation and visual cortex was measured after post-processing.The MTR value differences of the same area between two groups were compared by independent-sample t test or Satterthwaite t test if variances were not equality.Result The MTR value in the left and right optic radiation were ( 32.8 ± 2.2 ) ％ and ( 32.7 ± 2.0 ) ％ in the glaucoma group,(34.6 ± 1.4 )％ and (34.8 ± 1.3 )％ in the control group.There was a statistically significant difference between the two groups (left t =3.284,right t =4.040 ;P ＜ 0.01).The MTR value of the left and right visual cortex were ( 30.1± 2.0 ) ％ and ( 30.8 ± 1.8 ) ％ in the glaucoma goup,and (32.3 ± 1.2 )％ and (32.4 ± 1.2 )％ in the control group.Statistically significant difference was found between the two groups ( left t =4.319,right t =3.445 ;P ＜ 0.01).Conclusions Potential neuropathology changes occurring in the posterior visual pathway of patients with glaucoma indicate that the whole visual pathway may be involved by glaucoma.The micro physiological changes can be detected by MTI which can not be found by conventional MRI.It is a useful method of studying trans-synaptic damage of visual pathway n vivo glaucoma which provides more information for guiding the clinic diagnosis,cure and prognosis of glaucoma.

Background Researches showed that elevatory blood glucose level results in long-term damage of cells and tissue,or metabolic memory phenomenon,and manipulation of hyperglycemic memory is a good approach in the prevention of diabetic complications.However,its mechanism is not clear.It is speculated that the pathogenesis of diabetic retinopathy (DR) in diabetic patients may be associated to related mechanisms.Uncoupling proteins (UCPs) can decrease the production of reactive oxygen species (ROS),which may be related to DR.Objective This study was to explore the association between DR and the single nucleotide polymorphisms (SNPs) of UCP genes in Chinese Han population with type 2 diabetes.Methods A cross-sectional study was performed.This study was approved by Ethic Committee of Affiliated First Hospital of Shanghai Jiao Tong University and complied with Declaration of Helsinki,and written informed consent was obtained from each subject prior to any medical examination.One thousand eight hundreds and seventy-five patients with type 2 diabetes mellitus were enrolled in Xinjing district of Shanghai city by cluster sampling from November 2014 to January 2015.The demographic and medical baseline characteristics,ocular examination and laboratory tests were obtained and periphery blood of 2 ml was collected for extraction of DNA.Eight tag SNPs of UCP1,three tag SNPs of UCP2,and seven tag SNPs of UCP3 were selected as marker locus for the detection of genotype by Sequenom Mass ARRAY.Matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry platform were used for genotyping.Hardy-Weinberg equilibrium (HWE) analysis,allele and genotype frequencies,haplotype analysis,and association tests for DR and SNPs were performed by SAS and SHEsis software.Results A total of 530 DR patients were checked out from 1 875 subjects with type 2 diabetes mellitus,with the detection rate of 28.27％.rs660339 locn of UCP2 gene and rs1626521,rs668514 locus of UCP3 gene appeared to have low detectable rates,and the secondary allele base frequency of rs632862 in UCP2 gene was ＜0.01 and rs15763 of UCP3 gene was unmatched with HWE,therefore,these locus analysis was not included.In 13 SNPs locus included in the analysis,only 2 SNPs of UCP1 gene were related to DR.Compared with the non-diabetic retinopathy (NDR) patients,the G allele frequency of rs10011540 was increased (P =0.03,OR =1.31,95 ％ confidence interval[CI] =1.03-1.67,and T allele frequency of rs3811787 was decreased (P=0.04,OR=0.86,95％ CI=0.75-0.99) in DR patients.Genotyping detection showed that the C/C and A/A frequencies of rs3811790 in UCP1 gene were significantly more and C/A frequency was less in DR patients than those in NDR patients (all at P＜0.01).The logistic regression analysis indicated an association of SNPs of rs10011540 and rs3811787 with DR independent from glucose and disease duration.Conclusions The SNPs of rs10011540 and rs3811787 locus in UCP1 gene are associated with DR in Chinese type 2 diabetes patients.

Objective:To investigate the relationship between serum fibrous gel protein-3 (ficolin-3) and serum alanine (ALA) levels and gestational diabetes (GDM) .Methods:A total of 98 pregnant women with GDM admitted to our hospital from Jan. 2020 to Aug. 2020 were selected as the observation group, and 98 healthy pregnant women undergoing physical examination during the same period were taken as the control group. The level of serum ficolin-3 was measured by enzyme-linked immunosorbent assay (ELISA) , and the level of serum ALA was measured by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) . The two groups were compared in terms of serum ficolin-3, ALA levels and biochemical indicators (hemoglobin (HbA1c) , total cholesterol (TC) , high-density lipoprotein cholesterol (HDL-C) , low-density lipoprotein cholesterol (LDL-C) , serum total protein (TP) , serum urea (SU) levels) , and pregnancy outcomes. Pearson method was used to analyze the correlation between serum ficolin-3 and ALA levels and various biochemical indexes. Univariate analysis and binary logistic regression analysis were used to investigate the risk factors of GDM.Results:Serum ficolin-3, HbA1c, and SU levels in the observation group were all higher than that in the control group. Serum ALA level was lower than that in the control group, and the difference was statistically significant ( P<0.05) . TC, HDL-C, LDL-C, TPT showed no significant difference between the two groups ( P>0.05) . In the observation group, serum ficolin-3 was positively correlated with HbA1c and Su, and serum ALA was negatively correlated with HbA1c and SU ( P < 0.05) . The incidence of adverse outcomes including gestational neonatal asphyxia, neonatal jaundice, giant size, and amniotic fluid contamination in the observation group (26.53%) was higher than that in the control group (12.24%) , The difference was statistical significant ( P<0.05) . The univariate analysis showed that GDM was associated with age, weight gain during pregnancy, serum ficolin-3, ALA, HbA1c, SU, family history of diabetes ( P<0.05) ; Binary logistics regression analysis found that age ≥28 years, weight gain≥ 14 kg, serum ficolin-3≥24ng/ml, HbA1c 6.0%, and a family history of diabetes were risk factors for GDM, while serum ALA≥1.9 μg/ml was a protective factor of GDM, ( P<0.05) . Conclusion:The increase of serum ficolin-3 and the decrease of ALA level in pregnant women are risk factors of GDM, and have an adverse impact on the final delivery outcome

【Objective】 To explore the correlation between the severity of jaundice in ABO hemolytic disease of fetus and newborn (HDFN) and multiple indicators, in order to achieve accurate diagnosis, timely treatment, and prevent complications in ABO HDFN. 【Methods】 From March 2020 to February 2023, a total of 283 ABO HDFN in our hospital were classified into mild, moderate and severe groups based on total bilirubin levels. The differences in basic data, relevant laboratory indicators and the agglutination intensity of the three hemolysis tests were analyzed and compared. 【Results】 In the severe group, 75% (12/16) were male infants, which was significantly higher compared to 37.5% (57/152) in the moderate group (P<0.05). The values (mg/dL) of transcutaneous jaundice in the mild, moderate and severe groups were:forehead 9.88±1.93 vs 12.34±2.01 vs 15.56±2.69, face 10.25±2.27 vs 13.28±2.32 vs 15.99±2.86, chest 9.67±2.16 vs 12.51±2.11 vs 15.33±2.36, respectively. The values(µmol/L) of direct bilirubin (DBIL) and indirect bilirubin (IBIL) were 9.87±2.06 vs 11.90±2.59 vs 16.12±4.73, and 159.36±37.55 vs 252.98±30.52 vs 353.76±55.68, respectively, and the differences between the mild, moderate and severe groups were statistically significant (all P<0.05) . The creatine kinase (CK) values(unit/L) of mild, moderate and severe groups were 664.15±498.26 vs 500.51 ±451.63 vs 402.63±224.27, and the difference between the mild group and the other two groups was statistically significant (P<0.05) . There was no statistically significant difference in the agglutination intensity of the three hemolysis tests among HDFN with different severity of jaundice. 【Conclusion】 Clinicians can predict the severity of jaundice in light of gender, transcutaneous jaundice, DBIL, IBIL and CK of ABO HDFN, for further and graded treatment, so as to avoid the sequelae or even life-threatening consequences caused by ABO HDFN.

Objective To investigate the efficacy of lateral decubitus intramedullary nailing for treatment of subtrochanteric fractures of the femur.Methods From January 2012 to December 2015,23 patients with simple femoral subtrochanteric fracture were treated at Department of Orthopedic Trauma,Changhai Hospital.They were 15 males and 8 females,aged from 19 to 77 years (average,48.3 years).According to the Seinsheimer classification,there were 6 cases of type ⅡB,8 cases of type ⅡC,6 cases of type Ⅲ A,and 3 cases of type ⅢB.Their injuries were caused by traffic accident in 10 cases,falling from a height in 5 cases,and sprain in 8 cases.All patients were treated by closed reduction and anterograde intrarnedullary nailing at lateral decubitus.Their operative time,bleeding volume,fluoroscopic frequency,fracture healing time,functional recovery and complications were recorded and analyzed.Results Their operative time ranged from 55 to 80 min,averaging 65.7 min;their bleeding volumes ranged from 240 to 420 mL,averaging 304.3 mL;their fluoroscopic frequency ranged from 30 to 60 times,averaging 42.7 times.This cohort was followed up for 12 to 28 months (average,17.9 months).Their fracture healing time ranged from 4 to 10 months,averaging 5.5 months.Nonunion occurred in one patient but was cured by secondary operation.The HSS evaluation at the final follow-ups showed 17 excellent cases and 6 good ones,yielding an excellent to good rate of 100％.All the wounds healed by the first intention.No infection,deep vein thrombosis or implant failure was observed.Conclusion As lateral decubitus intramedullary nailing can achieve satisfactory clinical efficacy for subtrochanteric fractures of the femur,the body position of lateral decubitus may be a good alternative.
