In recent years, we have tried transfusion of large numbers of granulocytes in the patients withsevere infection due to gram-negative bacteria or the patients treated with various types of antibioticswithout effect. The results were quite satisfactory. We know from experience that the curative effectis related to the number of the granulocytes transfused. Only by increasing it to 6-8?109 or 6-8?1016 the curative effect can be achieved.

Effects of squalene, algae (Enteromorpha prolifera), laver (Prophyra hai-tanensis) and cauliflower on serum total cholesterol (T-C), high density li-poprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) and very low density lipoprotein cholesterol (VLDL-C) were separatly observed in Wistar male albino rats fed on a diet containing 0.5% cholesterol,5% lard and 0.5% bile salt. Squalene was supplemented at 5% of the diet, and algae, laver, cauliflower at 10% of the diet.After the rats had been fed on the diet described above for 30 days, serum T-C, HDL-C, LDL-C and VLDL-C levels were determined. The results showed that the rats fed on a diet containing 5% squalene or 10% algae were significantly lower in serum T-C, HDL-C and VLDL-C but higher in serum HDL-C than those of the controls, and the rats fed on a diet containing 10% laver or 10% cauliflower were significantly lower in serum T-C than that of the controls.

Nutrition studies were made on four divers performing a helium-oxygen saturation dive to a simulated depth of 200m in a hyperbaric chamber for about seven days. Daily intake of food was surveyed by regular weighing method and its calories and nutrients were calculated from Chinese food composition table. Fasting blood and 24h urine samples were collected on several occasions before, during and after the dive for estimation of free amino acid, nitrogen and minerals. Vitamin load test was conducted for evaluation of vitamin status. The results showed that during the dive intakes of cereal, meat and oil of divers were decreased, but vegetable, fruit and beverage intakes increased. An average body weight loss of 1.75 kg was found after a 7-day period, but little changes in the body fat. Free amino acid levels of serum and urinary output were reduced, especially the essential amino acids. The urinary excretion of minerals was in an acceptable range, but thiamin decreased markedly and not returned to an acceptable range until 10 days after leaving the hyperbaric chamber.

Objective:To determine the seroprevalence of celiac disease in susceptible population, and to analyze the relationship between demographic characteristics, dietary habits, lifestyle and serological positivity so as to provide guidance for the prevention and treatment of celiac disease in Southern China.Methods:A total of 1 273 individuals who participated in Guangdong Province Health Screening Program in 2015, were selected as serologically positive subjects of celiac disease, including people with irritable bowel syndrome, colitis, diarrhea, anemia, low BMI, short stature, type 1 diabetes mellitus (T1DM), rheumatoid arthritis (RA), ankylosing spondylitis, psoriasis and bristol grade=6 or 7. All subjects were tested for serum IgA anti-tissue transglutaminase antibodies (TTGA), IgA antibodies against deamidated gliadin peptides(DGPA) and IgG against deamidated gliadin peptides (DGPG). Dietary habits, lifestyle and demographic characteristics were compared in subgroups.Results:The seroprevalence of celiac disease in susceptible population was 0.94% (95% CI 0.54%-1.64%) including 0.08% (1/1 273) for TTGA, 0.47% (6/1 273) for DGPA, and 0.39% (5/1 273) for DGPG. The seropositive rate was 3.6% (1/28) in patients with psoriasis, 2.1% (2/95) in the low BMI group, 1.9% (1/53) in T1DM group, 1.8% (3/169) in diarrhea group and 1.1% (5/463) in RA group. No significant difference was found in age, gender, high carbohydrate diet or lifestyle between the negative and the positive subjects. Conclusions:In Southern China, the seropositive rate of celiac disease is 0.94% in susceptible population, which prompts an urgent need of serological screening for early diagnosis.

Bilingual teaching is a necessary product in the field of both English teaching and professional courses teaching induced directly by a purpose to catch up with international education level during the process of educational reforms.Yet few researches launched to study possible ways which may improve the curriculum model have been reported in the last five years.In order to follow up the previous studies and present fresh ideas as well as conclusions,this survey reflects the current status of bilingual teaching in eight-year M.D.program from the perspectives of both the teachers and students via questionnaire analysis together with face to face interviews.Moreover,our survey expresses underlying deficiencies of this teaching system from brand-new aspects which have never been discussed before along with their corresponding solutions objectively.

Objective To explore the clinical effect of acupuncture on acute renal injury of sepsis.Methods From January 2015 to May 2017,adult patients with sepsis who received ≥ 7 days of treatment were collected from the Central Hospital of Zhuzhou.The participants were randomly divided into the control group (n =35) and the treatment group (n =37),and the control group was given routine treatment according to the sepsis guidelines.On the basis of control group,the treatment group was given acupuncture treatment,acupoints Shenshu and Sanyinjiao,Taixi,Zusanli.The clinical effects of the two groups of patients were compared.Results The levels of cystatin C,blood urea nitrogen and creatinine in the treatment group were significantly lower than those in the control group (P ＜ 0.05).There was no significant difference in the number and proportion of patients with blood purification between the two groups (P ＞ 0.05),while the frequency and time of blood purification treatment in the treatment group were significantly lower than those in the control group (P ＜ 0.05).The levels of blood interleukin-6 and tumor necrosis factor-alpha in the treatment group were significantly lower than those in the control group (P ＜ 0.05).From the fourth day of treatment,the Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score in the treatment group was significantly lower than that in the control group (P ＜ 0.05).There was no significant difference in mortality between the two groups at 28 days (P ＞ 0.05).Conclusions Acupuncture of Shenshu,Sanyinjiao,Taixi,Zusanli can improve sepsis patients with acute kidney injury in renal function.

Objective:To investigate the preventive effect of postoperative pancreatic fistula by pedicled omentum wrapping pancreaticojejunostomy in pancreaticoduodenectomy.Methods:The clinical data of 78 patients who underwent pancreaticoduodenectomy in Songjiang Hospital Affiliated to Shanghai Jiao Tong University from September 2017 to August 2020 were retrospectively analyzed. Patients were divided into the modified pancreaticojejunostomy group (conventional approach group, n=43) and the pedicled omentum wrapping pancreaticojejunostomy group (omentum wrapping group, n=35) according to the surgical mode. Postoperative pancreatic fistula, postoperative abdominal bleeding, delayed gastric emptying and postoperative hospital stay were compared between the two groups. Results:Compared with the conventional approach group, the postoperative pancreatic fistula rate in omentum wrapping group was significantly reduced (2.9% vs 18.6%), and the difference was statistically different ( P=0.030); postoperative abdominal bleeding rate(0 vs 4.7%)and the delayed gastric emptying rate were significantly reduced (8.6% vs 25.6%), but both of them were not statistically different ( all P value>0.05); the length of postoperative hospital stay was significantly reduced [(11.3±2.9) days vs (12.8±3.5)days], and the difference was statistically different ( P=0.045). Conclusions:The pedicled omentum wrapping pancreaticojejunostomy was simple and convenient, which can significantly reduce the rate of postoperative pancreatic fistula. It can shorten the time of the length of hospital stay after surgery.

tRNA-derived small RNAs (tsRNAs) are novel non-coding RNAs that are involved in the occurrence and progression of diverse diseases. However, their exact presence and function in hepatocellular carcinoma (HCC) remain unclear. Here, differentially expressed tsRNAs in HCC were profiled. A novel tsRNA, tRNA^Gln-TTG derived 5'-tiRNA-Gln, is significantly downregulated, and its expression level is correlated with progression in patients. In HCC cells, 5'-tiRNA-Gln overexpression impaired the proliferation, migration, and invasion in vitro and in vivo, while 5'-tiRNA-Gln knockdown yielded opposite results. 5'-tiRNA-Gln exerted its function by binding eukaryotic initiation factor 4A-I (EIF4A1), which unwinds complex RNA secondary structures during translation initiation, causing the partial inhibition of translation. The suppressed downregulated proteins include ARAF, MEK1/2 and STAT3, causing the impaired signaling pathway related to HCC progression. Furthermore, based on the construction of a mutant 5'-tiRNA-Gln, the sequence of forming intramolecular G-quadruplex structure is crucial for 5'-tiRNA-Gln to strongly bind EIF4A1 and repress translation. Clinically, 5'-tiRNA-Gln expression level is negatively correlated with ARAF, MEK1/2, and STAT3 in HCC tissues. Collectively, these findings reveal that 5'-tiRJNA-Gln interacts with EIF4A1 to reduce related mRNA binding through the intramolecular G-quadruplex structure, and this process partially inhibits translation and HCC progression.
