1.The sensation and transduction of mechanical stimulus in cells
Chinese Journal of Pathophysiology 1986;0(03):-
Mechanical stresses modulate almost all aspects of cell function, including growth, differentiation, migration, gene expression, protein synthesis and apoptosis. Thus, uncovering the mechanisms by which living cells sense and transduce mechanical stress lies at the core of understanding how they respond and adapt to their physical environments. In this review, the possible mechanism about cell response to mechanical stimulus was discussed from outer cell membrane to inner nucleus.
2.Diagnosis and treatment for gastrointestinal stromal sarcomas
Chinese Journal of Primary Medicine and Pharmacy 2010;17(6):729-730
Objective To explore the clinical behavior,pathological and immunohistochemical characteristics and diagnosis, treatment methods of gastrointestinal stromal sarcomas (GISS). Methods Retrospective analysis was perfomed over 36 GISS patients based on clinical data and pathological data. Results GISS occurred more in the stomach and small intestine, than colon and rectum. Immunohistochemical staining showed CD117, CD34 expression,the positive rates were 91.7% and 86. 1%. Conclusion GISS is a rare malignant tumor, GISS diagnosis depends on the histologic and immunohistochemical test. CD34 and CD117 in the positive diagnosis has its special significance. Surgery is the main treatment.
3.Perioperative nursing of patients receiving colorectal tumor surgery under peritoneoscope
Chinese Journal of Practical Nursing 2009;25(3):12-14
Objective To discuss the perioperative nursing method for patients receiving colorec-tal tumor surgery under peritoneoscope. Methods Using the nursing procedure, through appraisal of patients' health situation→listing the nursing diagnosis or the nursing questions→formulation of nursing plan→ implementation of nursing plan→appraisal of the expected effect, combination of the surgical nursing's characteristic, to practice the idea of "the perfect person health and concern", cooperation with medical and nursing team, we provided a complete treatment and nursing plan for 38 patients receiving colorectal tumor surgery under peritoneoscope. Results 38 patients made satisfactory results with no surgery complications. The average in-hospital time was 9 days. Conclusions This technology has slight wound,light hemorrhage,slight draw-off, less pain, short exposure time of intestine, fast recovery of intestine function and early food intake. Systematic and intact perioperative nursing can improve the nursing quality and the success rate and reduce the complications so that the patients can live through the surgery safely.
4.The mechanism and prevention of bronchial pulmonary dysplasia
International Journal of Pediatrics 2016;43(9):692-695
Bronchopulmonary dysplasia is one of the causes of affecting children′s health,which has a complicated etiology,including the gene level of internal aspect and some external factors, such as premature birth inducing the pulmonary hyperplasia,infectious diseases caused by low immunity,complications caused by clinical interventions,and the low quality of respiratory tract management. In the article,we review the research progress about mechanism and prevention of BPD in domestic and overseas in recent years.

Objective To observe the clinical effect of procedure for prolaps and hemofrhoids (PPH) in treatment of mixed hemorrhoids combined with non-functional obstructed defecation syndromes (ODS).Methods The clinical data of 50 patients with mixed hemorrhoids combined with non-functional ODS treated by PPH were retrospectively analysed.All these patients were followed up for 12 months,the treatment outcome was observed.Results Eleven cases were basic cured,apparently effective in 12 cases,and effective in 12 cases,invalid in 15 cases,the total effective rate was 70% (35/50),inefficacy patients were mainly combined with rectocele.None patients had serious complications such as death,anastomotic infection and pelvic sepsis.Conclusion PPH convenient operation,small trauma,for the treatment of mixed hemorrhoids combined with internal rectal prolapse is safe and effective,but the effective is poorer in treatment of mixed hemorrhoids combined with rectocele.

Objective To evaluate the cooperative effect of intraperitoneal adenoviral p53 gene therapy together with thymosin ?1 against peritoneal carcinomatosis. Methods KM mouse model bearing peritoneal carcinomatosis was established using H22 cell line. 48 hours after inoculation, adenoviral-mediated p53 gene was administrated intraperitoneally alone, or combined with thymosin ?1 within 7 days. The abdominal girth, body weight, tumor cell number, apoptosis and cell cycle were tested using methods of cell counting and flow cytometry. Results Adenoviral p53 gene transfer alone arrested H22 cell in G0/G1. In combination therapy group, ascitic fluid was obviously halted, tumor cells in peritoneal cavity decreased in number and ascites formation, dead cell ratio was elevated. Conclusion Adenoviral-mediated p53 gene could block cell proliferation. Intraperitoneal adenoviral p53 gene therapy combined with thymosin ?1 showed synergism for the lethal damage and inhibition for peritoneal carcinomatosis.

Eleven salt-losers (SL group) and eleven non-salt-losers (NSL group) of congenital a-drenal hyperplasia due to 21-hydroxylase deficiency (21-OHD) were evaluated for sodium status under routine regimen of glucocorticoid (4 salt-losers with mineralocorticoid at the same time). Venous samples were collected for the measurement of plasma renin activity (PRA), aldosterone (Aldo) , and a-drenocorticotropin (ACTH), and for serum cortisol (F), 17-OH progesterone (17-OHP), and testosterone (T). Urine samples were collected for 17-ketosteroid (17-KS). 10 age-matched normal children were chosen as control. The results showed that concentration of PRA, Aldo, 17-OHP, and T, were higher in both groups than in normal subjects (P

Objective To investigate the curative effects of laparocopic treatment for cystiduodenal internal fistula. Methods All procedures were conducted under laparoscope. After the exposure of the cholecystic base, trans-cholecystic cholangiography was performed to detect the relations between the cholecyst and neighboring organs. Once the internal fistula was confirmed, the orifice of fistula was closed laparoscopically. Then abdominal drainage, gastrointestinal decompression, and administration of somatostatin were routinely employed. Results In a series of 327 cases of laparoscopic cholecystectomy (LC) with intraoperative cholangiography, a total of 6 cases of cystiduodenal internal fistula were detected, all of which were anatomized and closed successfully under laparoscope. No postoperative hemorrhage or duodenal bile leakage occurred. Conclusions Routine intraoperative cholangiography during LC is beneficial to the detection of the cystiduodenal internal fistula.Effective and reliable management rests upon skillful laparoscopic techniques of dissection and fistula closure, as well as the supportive treatment.

Objective To investigate the relationship between pharmacokinetics(PK) and pharmacodynamics PD of epigoitrin,a main component in total alkaloids of Radix Isatidis,in yeast-induced febrile rats with the combined PK-PD model.Methods The plasma concentration of epigoitrin after ig administration with total alkaloids of Radix Isatidis was determined by HPLC method and the body temperature was recorded by electronic thermometer.The individual PK parameters were fitted using one compartmental model.The PD parameters were fitted by three kinds of PK-PD binding models,such as indirect inhibition-Kin model,indirect stimulation KoutPD model,and Sigmoid-Emax model.Results The main PK parameters t1/2,Cmax,AUC were(4.94?0.84) h,(4.01?0.21) ?g/mL,(28.37?2.42) ?g?h/mL and(5.71?0.91) h,(4.15?0.25) ?g/mL,(30.35?2.58) ?g?h/mL in both normal and febrile rats,respectively.The relationship between pharmacological effects and effect compartment concentration was better fitted with the indirect inhibition-Kin PD model.The corresponding PD parameters were Kin=(0.70?0.10) h-1,Kout=(0.54?0.12) h-1,R0=1.33?0.16,IC50=(0.94?0.66) mg/L.ConclusionThe PK parameters of epigoitrin in total alkaloids of Radix Isatidis show that there is no significant difference in PD behavior in vivo in both normal and febrile rats.Relationship between in vivo PK and PD of epigoitrin in febrile rats is established using indirect inhibition Kin model.
