Objective To observe the clinical effect of sling exercise therapy(S-E-T)combined with drug treatment for cervical vertigo in elderly patients.Methods Forty-nine elderly patients with cervical vertigo admitted to our hospital between January 2011 and July 2014 were randomly divided into an observation group(n=27)and a control group(n=22).The observation group was given 80 mg Ginaton(Extract of Ginkgo Biloba Leaves Tablets)produced by German Dr.Willmar Schwabe GmbH & Co.KG three times a day,combined with S-E-T,including cervical stability and stretching training for 40min,focusing on the neck global muscle and local stabilize muscle rehabilitation,once every other day.The control group was provided with the same drug treatment.During the 6-month intervention,both groups were given health education by the same therapist.Both groups were assessed using the neck disability index(NDI),visual analogue scale(VAS)and evaluation scale for cervical vertigo(ESCV) before and after the intervention,as well as at the last follow-up visit.Before the treatment and at the last follow-up visit,the cervical X-ray examination and trigger point check were also conducted for both groups.Results All the forty-nine patients were followed up for 4.83 to 6.70 months,with an average of(6.01 ± 0.49)months.Significant improvement was observed in the average ESCV score for both groups after the treatment.Compared with before the treatment,there was significant improvement in the average NDI and VAS right after the treatment and at the last follow-up visit in the observation group,but only at the last follow-up visit in the control group.From the cervical X-ray,no significant differences were found in the vertebral osteophyte formation,facet joints and uncovertebral joint degeneration between the 2 groups(P＞0.05),while significant differences were observed in the number of the neck trigger points(P＜0.05).Conclusion The sling exercise therapy combined with drug treatment can significantly improve cervical function,relieve pain and vertigo symptoms in elderly patients with cervical vertigo.The effect is better than drug treatment alone.

Microbial oil, as raw material for biodiesel, can be produced by Trichosporon cutaneum B3 using cassava starch hydrolysate. Batch cultures demonstrated that there was little inhibitory effect with the concentration of cassava starch hydrolysate up to 90 g/L. The favorable initial pH, C/N molar ratio, nitrogen source and its concentration were 6.0, 116, yeast extract and 3.0 g/L, respectively. Under the optimized conditions, dry biomass reached 15.2 g/L and lipid content reached 40.9% after culture for 144 h in flask. Batch cultures in a 2 L stirred-tank fermenter were run for 44 h and resulted in dry biomass, lipid content and lipid yield of 28.7 g/L, 42.8% and 12.27 g/L, respectively. The chemical compositions of biodiesel prepared from lipids of T cutaneum B3 mainly included palmitic acid methyl ester, stearic acid methyl ester, oleic acid methyl ester and linoleic acid methyl ester etc., and its main physicochemical properties were in compliance with relevant national diesel standards. Therefore, the biodiesel prepared from lipids of T cutaneum B3 can serve as a potential fossil fuel alternatives.

OBJECTIVETo evaluate the application of small intestine double stoma and succus entericus reinfusion in the patients with severe intra-abdominal infection.

METHODSTen patients with high intestinal perforation from February 2005 to November 2014 were enrolled in the study. All the cases received emergency operation. Small bowel with intestinal perforation was resected, and double stoma was applied in the proximal and distal small intestine. When abdominal infection under control, total enteral nutrition was successfully administered from nasogastric tube. The succus entericus from the proximal intestine was collected and transfused back to the distal intestine. Stool was collected and fecal nitrogen, fat and carbohydrate contents were determined. Related serum protein levels were measured.

RESULTSAs compared to pre-reinfusion, the absorption rate of carbohydrate [(90.9±7.8)% vs. (82.7±15.2)%], fat [(87.6±6.4)% vs. (59.1±10.8)%], and nitrogen [(82.4±9.8)% vs. (67.2±15.4)%] increased after succus entericus reinfusion (P<0.05). The serum protein levels increased significantly as well[fibronectin: (285.6±3.6) vs. (157.0±22.6) mg/L, P<0.01; transferrin: (4.86±0.21) vs. (3.60±0.25) g/L, P<0.05; pre-albumin: (291.3±112.5) vs. (199.1±53.3) mg/L, P<0.05].

CONCLUSIONSmall intestine double stoma and succus entericus reinfusion are effective in improving the absorption of carbohydrate, fat and nitrogen in the patients with severe intra-abdominal infection.

Gastric cancer is one of the most common malignant tumors. Traditional Chinese medicine (TCM) has been widely used in treatment of gastric cancer, but still lacking large sample controlled trial to evaluate its efficacy.

The mammalian liver has a very strong regeneration capacity after partial hepatectomy (PH). To further learn the genes participating in the liver regeneration (LR), 551 cDNAs selected from subtracted cDNA libraries of the regenerating rat liver were screened by microarray, and their expression profiles were studied by cluster and generalization analyses. Among them, 177 genes were identified unreported and up- or down-regulated more than twofold at one or more time points after PH, of which 62 genes were down-regulated to less than 0.5; 99 genes were up-regulated to 2-10 folds, and 16 genes were either up- or down-regulated at different time points during LR. By using BLAST and GENSCAN, these genes were located on responsible chromosomes with 131 genes on the long arms of the chromosomes. The cluster and generalization analyses showed that the gene expression profiles are similar in 2 and 4, 12 and 16, 96 and 144 h respectively after PH, suggesting that the actions of the genes expressed in the same profiles are similar, and those expressed in different profiles have less similarity. However, the types, characteristics and functions of the 177 genes remain to be further studied.

Objective:To determine a relationship between ultrasound shear wave elastography (SWE) and pathological lessions of renal tissues in children with chronic kidney disease (CKD).Methods:It was a cross-sectional observational study, involving children admitted to the Department of Pediatrics of Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from January to December 2021 with definite pathological diagnosis through kidney biopsy. The SWE was used to determine the Young's modulus (elastic modulus) of the cortex and medulla of the upper, middle, and lower poles of the kidney. The renal histopathology was classified or graded. The statistical method was used to analyze the relationship between Young's modulus of the inferior polar cortex (YM cor) and medulla (YM med) of the right kidney and renal pathology. Results:The study included 110 children with definite pathological diagnosis through renal biopsy, aged (10.1±3.4) years old (2-17 years old), with 55 males (50.0%). The body mass index was (20.6±2.4) kg/m 2, and mean arterial pressure was (95±24) mmHg. There were 94 patients (85.4%) with CKD stage 1, 8 patients (7.3%) with CKD stage 2, and 8 patients (7.3%) with CKD stage 3. There was no significant difference of YM cor and YM med in the upper and middle poles of the right kidneys, and YM med in the lower poles of right kidneys in CKD patients with different stages (all P>0.05). Both YM cor [(15.75±3.36) kPa] and YM med [(13.50±2.43) kPa] of CKD stage 3 patients were significantly higher than those of CKD stage 1 patients [(12.94±2.45) kPa, (11.88±2.23) kPa](both P<0.05). There was no significant difference of YM cor and YM med in the lower poles of right kidneys between stage 1 and stage 2 CKD patients (both P>0.05). YM cor[(17.93±3.23) kPa] and YM med [(15.50±1.48) kPa] in patients with crescentic glomerulonephritis were higher than those in patients with focal segmental glomerulosclerosis [(12.71±2.42) kPa, (11.57±2.63) kPa] and mesangial proliferative glomerulonephritis [(12.73±2.04) kPa, (11.48±2.10) kPa](all P<0.05). There was no significant difference of YM cor and YM med between focal segmental glomerulosclerosis and mesangial proliferative glomerulonephritis (both P>0.05). YM cor [(16.30±2.63) kPa] and YM med [(15.54±1.59) kPa] of Lee's Ⅳ grade of IgA nephropathy were higher than those of Lee's Ⅲ grade [(13.32±2.70) kPa, (12.57±2.50) kPa](both P<0.05), while the International Study of Kidney Disease in Children grade of purpura nephritis had no significant correlation with YM cor and YM med (both P>0.05). YM cor [(15.41±2.37) kPa] and YM med [(13.82±2.59) kPa] of interstitial fibrosis/tubular atrophy (T1/T2) group of IgA nephropathy mixed with purpura nephritis were significantly higher than those of T0 group's [(12.99±2.40) kPa, (11.79±2.05) kPa] (both P<0.05). Moreover, crescent formation (C1) group had a higher YM cor [(14.21±2.77) kPa] and YM med [(12.80±2.47) kPa] than those in C0 group [(12.73±2.15) kPa, (11.59±1.97) kPa] (both P<0.05), while YM cor and YM med were unrelated to the mesangial hypercellularity (M), endocapillary cellularity (E), segmental sclerosis or adhesion (S) indicators (all P>0.05). In lupus nephritis patients, YM cor ( r=0.744, P=0.035) and YM med ( r=0.728, P=0.009) were favorably linked with the chronic index, but not with the activity index (both P>0.05). Conclusions:Renal interstitial fibrosis/tubular atrophy and crescentic development are connected with YM cor and YM med at the lower pole of the kidney as measured by SWE. SWE can be used to assess the chronic renal lesions in children with CKD in the early and middle stages. It may develop into a new noninvasive way to assess renal pathology.

Objective:To investigate the prognosis and risk factors of IgA vasculitis nephritis (IgAVN) in children.Methods:A retrospective cohort study was conducted. Clinical data were collected from 264 children who were pathologically diagnosed with IgAVN at Department of Pediatric Nephrology, Tongji Hospital, affiliated with Tongji Medical College, Huazhong University of Science and Technology, between January 2011 and December 2017. All patients had a follow-up period of more than 3 years. Clinical characteristics, renal pathology, 3-year and 5-year prognosis were analyzed. The patients were grouped based on gender, age of onset (≤6 years, >6-9 years, and >9 years), pathological classification (≤Ⅲ and>Ⅲ),whether the prognosis was complete remission at 3 and 5 years. Independent sample t-tests, ANOVA or chi-squared test were used for intergroup comparisons. Spearman correlation analysis was applied for ordinal data, and multivariate Logistic regression was used to analyze factors affecting the prognosis. Receiver operating characteristic (ROC) curve was utilized to evaluate the predictive value of these factors. Results:Of the 264 children with IgAVN, 153 were male and 111 were female, the age of onset was 8.3 (6.7, 10.3) years, 118 patients (45%) with onset age >6-9 years accounted for the highest proportion. All patients presented with skin purpura and renal involvement, primarily manifesting as hematuria and/or proteinuria. Microscopic hematuria was observed in 253 patients (95.8%), while 246 patients (93.2%) showed proteinuria. In 256 patients (97.0%), hematuria or proteinuria urinalysis was detected within 6 months of skin purpura onset, and 243 patients (92.0%) underwent renal biopsy within 6 months of renal involvement. The most common clinical subtype in 264 IgAVN children was hematuria and proteinuria (204 cases, 77.3%), with grade Ⅲ being the predominant pathological classification (181 cases, 68.6%). Among children ≤6 years old, the 3-year complete remission rate was higher in males than in females (83.9% (26/31) vs. 7/16, χ2=8.12, P=0.012). Factors independently associated with poor 5-year prognosis included time from hematuria or proteinuria urinalysis to renal biopsy >6 months, elevated serum cholesterol levels, and incomplete remission 3 years post-biopsy ( OR=5.41, 1.39, 6.02, 95% CI 1.40-20.86, 1.04-1.84, 2.61-13.88, all P<0.05). The serum cholesterol has a predictive value for 5-year prognosis ( P=0.020, AUC=0.62, 95% CI 0.52-0.71, Youden index=0.27, cutoff=4.37). Conclusions:For children with IgAVN aged≤6 years, the 3-year prognosis is better in males than in females. Time from hematuria or proteinuria urinalysis to renal biopsy >6 months, elevated serum cholesterol levels, and incomplete remission at 3 years post-biopsy may be independent risk factors for poor 5-year prognosis in children with IgAVN.
