Chinese Journal of Pancreatology 2009;9(2):121-124
Objective To detect the expression of islet amyloid polypeptide (IAPP) in the pancreatic tissues of patients with pancreatic cancer,and to explore the relation between diabetes and pancreatic cancer.Methods Surgically-removed 28 pancreatic cancer samples and adjacent normal pancreatic tissues were studied.Among these patients there were 12 patients complicated with diabetes while other 16 patients did not.Immunohistoehemieal method and Western blot method were used to detect the expression of IAPP in different tissue specimens.Results lAPP expressed in human pancreatic islet cell cytoplasm.Immanohistochcmical index of pancreatic cancer and adjacent normal pancreatic specimens of patients with diabetes,and pancreatic cancer and adjacent normal pancreatic specimens of patients without diabetes were 283 305±91 627,122 874±86 917,154 032±81 097 and 105 797±67 593,respectively;the relative IAPP expressions were (173.1±23.5) %,( 119.4±18.4) %,( 148.7±28.3 ) % and 100%.Irrespective of the presence of diabetes,expression of IAPP in pancreatic cancer specimens was significantly higher than that in adjacent normal pancreatic specimens ( P < 0.01 );expression of IAPP in pancreatic cancer plus diabetes specimens was significantly higher than that in pancreatic cancer specimens without diabetes (P <0.01 );expression of IAPP in adjacent pancreatic specimens complicated with diabetes was significantly higher than that in adjacent pancreatic specimens without diabetes ( P < 0.05).Conclusions LAPP participated in the course of diabetes and pancreatic cancer,and may be the common pathogenesis of the two diseases.
3.Clinical and pathological features of 37 children with IgA nephropathy
Journal of Clinical Pediatrics 2001;(1):41-42
To explore the relationship between clinical findings and pathological changes of IgA nephropathy (IgAN), 37 children with IgAN were undertaken clinical classification and renal-pathological comparison including glomerulus change, renal tubule-interstitial change and immunopathology. The results showed that there were 18 (49%) cases with hematuria, 14 (38%) cases with nephrotic syndrome, 3(8%) cases with both of hematuria and proteineuria, and 2 (5%) cases with nephritic syndrome in the clinical classification. 54% of cases with glomerulus changes was as class III. No significant relationship was found between clinical classification and glomerulus changes. There were 24 cases with renal-tubule interstitial changes and 7 cases with hematuria. 43% of them were classified as class I and 57% as class II.All cases with nephrotic syn-drome developed renal tubule-interstitial change. 78% (11 cases) of them were as class II and 22% (3 cases) as class III. Besides, 2 of 3 cases with both of hematuria and proteineuria and 1 of 2 cases with nephritic syndrome also manifested renal tubule-interstitial change. There were four phenotypes were observed in immunopathology including 16 cases of them as IgA, 6 cases as IgAG, 10 cases as IgAM and 5 cases as IgAGM, respectively. 66% of cases with hematuria was found as IgA and 50% of cases with nephrotic syndrome as IgAM. It is concluded that hematuria can be a main clinical finding in both of IgAN and nephrotic syndrome. Glomerulus changes is usually not correlated with clinical classification. There is a significant renal tubule-interstitial change in cases with nephrotic syndrome. Hematuria is usually as IgA and nephrotic syndrome as IgAM in immunopathology.
4.Whole exome sequencing in the application of hereditary breast cancer susceptibility gene discovery
Tianjin Medical Journal 2017;45(6):660-662
Genetic susceptibility factor is one of the important reasons to induce breast cancer. Breast cancer risk variants are divided into three categories including high, moderate and low penetrances. Traditional BC susceptibility gene discovery approaches limit the search for breast cancer susceptibility genes with high and moderate risk variants. Whole exome sequencing technology provides a quick and efficient method to discover breast cancer susceptibility genes. At present, a number of breast cancer susceptibility genes have been identified by whole exome sequencing method, which provides useful guidance for the risk assessment and pathogenesis of hereditary breast cancer. In this paper, we reviewed the whole exome sequencing technology and discussed the experimental design, data filtering strategy, statistical significance and correlation analysis.

The CT images of 42 pathologically confirmed cases of gastrointestinal stromal tumors were reviewed, and compared with pathological results. In 20 cases, the lesions were located in stomach, 21 in small intestine, 1 in mesentery. In 18 cases pathologically confirmed as benign tumors, 16 were positive on CT scan, which presented round solid mass with homogeneous density, mean diameter of 3.8 cm (2 -6 cm), homogeneous enhancement on post-contrast scan. In 21 malignant cases all were on CT scan, which presented irregular or lobulated solid mass with heterogeneous density and cystic change inside, mean diameter of 10. 1 cm (4 - 30 cm) , heterogeneous enhancement with no enhancement in cystic part. In 3 potentially malignant cases, CT images showed irregular solid mass with homogeneous density, diameter of 4 - 8 cm, homogeneous enhancement in post-contrast scan. CT scan can accurately show the location and size of gastrointestinal stromal tumors, and is of important diagnostic value.

OBJECTIVETo observe the effect of Tai Ji Quan (TJQ) training on strength and function of lower limbs in the aged.
METHODSSixty senile subjects were recruited and assigned to the TJQ group and the control group (imparting health knowledge)by random digit table. Patients in the TJQ group received 24-style TJQ training for 18 months (60 min each time, 5 times per week), while those in the control group were imparted with sarcopenia related causes, pathogeneses, prevention and control measures. The maximum isometric strength of bilateral iliopsoas, quadriceps femoris, tibialis anterior muscle, hamstrings; the time for 5 sitting-up tests and Time Up and Go Test (TUGT), one-leg standing time with closed eyes test; and the score of Berg balance scale were compared between the two groups.
RESULTSCompared with before treatment, muscle strength increased in the TJQ group with an average increased capacity (rate) as follows, bilateral iliopsoas 5.5 kg (16.9%), quadriceps femoris 5.5 kg (26.2%), and tibialis anterior muscle 8.5 kg (36.2%) (all P < 0.05). The time for TUGT and 5 sitting-up tests was shortened by 1.3 s (16.7%) and 0.9 s (14.5%) respectively in the TJQ group. The time for one-leg standing time with closed eyes test was increased by 8.4 s (left) and 9.1 s (right) respectively. The score of Berg balance scale increased by 4.3% (P < 0.05). Compared with the control group, bilateral quadriceps femoris and tibialis anterior muscle strength increased significantly (P < 0.01); the time for TUGT and 5 sitting-up tests, the time for one-leg standing time with closed eyes test, scores of Berg balance scale were all improved in the TJQ group after intervention (P < 0.05).
CONCLUSIONTJQ training could improve strength of iliopsoas, quadriceps femoris, tibialis anterior muscle in the aged, elevate their balance and locomotor activities, and possibly prevent and treat sarcopenia.
