Journal of Clinical Surgery 2017;25(1):75-77
Gastroesophageal reflux disease and sliding hiatal hernia are chronic disease,and sometimes there are not typical clinical symptoms.Patients don't have enough cognition or put enough em-phasis on it.Determining the sliding length of the sliding hiatal hernia and gastroesophageal reflux disease respectively by means of high resolution manometry and 24 hour pH monitoring,in turn,analyzing the rela-tionship between sliding length of the sliding hiatal hernia and gastroesophageal reflux disease.
2.Design of Pyrolyzing Furnace Temperature Measurement Node Based on WSN Technology
Chinese Medical Equipment Journal 2004;0(09):-
Objective To propose a design of pyrolyzing furnace temperature measurement node based on WSN technology. Methods The chip MAX6675 was applied in the temperature measure circuit in the system. It simplified the design of hardware and software and improves precision of control system. The chip CC2420 was adopted as the frequency transceiver. The operating system TinyOS which was developed by the University of California at Berkeley was also adopted. Results We accomplished the design of temperature data acquisition module,wireless communication module and power management module,which had many features,such as simple structure,small size and high precision. Conclusion The node has effectively improved the functional reliability of pyrolyzing furnace,giving a solid base to promote the application of WSN technology on medical vehicle.

Objective To observe the injuries of sodium citrate plasma(scP) on the growth and function of HepG2 cells.Methods The HepG2 cells were cultured.The viability,cell cycle and apoptosis,the leakage of LDH,total protein,glutathione and the changes on morphology of hepatocytes exposured to scP were investigated.Results The viability of HepG2 cells was inhibited when the cells were cultured in scP for 24h(F=37.108,P=0.001).After 48h,nearly all cells died except cells in 10% scP group.After the cells were exposed to scP for 24h,the percentage of S phase of the cell cycle and the rate of apoptosis were significantly increased compared to those of the control.The leakages of LDH were increased in the HepG2 following exposure to scP for 5h(P

·Uveitis is an inflammation of any or all parts of the uveal tract including the iris, ciliary body and the choroid. Despite current advances in diagnosis and management, visual loss occurs in 35%-45% of patients with uveitis. The etiopathogenesis of uveitis remains unknown; it may be associated with environmental and immunogenetic factors. Many studies have demonstrated polymorphisms in major histocompatibility complex (MHC) genes may determine involvement in uveitis. Recently polymor-phisms in non-MHC genes, including cytokine and che-mokine genes, have been reported to play important roles in the pathogenesis of uveitis. This article reviewed the advances in the studies on cytokine and chemokine gene polymorphisms associated with uveitis.

Objective To investigate the change of the inflammatory marker high-sensitivity C-reactive protein(HS-CRP) and the immune marker neopterin in patients with acute coronary syndrome(ACS).Methods The study population included 40 patients with acute myocardial infarction(AMI) and 40 patients with unstable angia pectons(UAP).At the same time,we selected 80 patients with chronic stable angia pectons.Serum levels of HS-CRP,neopterin were measured by means of ELISA.Results HS-CRP and neopterin were significantly higher in acute coronary syndrome group than those in chronic stable angina group.Conclusion HS-CRP and Neopterin are elevated in acute coronary syndrome.They can be used as the certain diagnosetic value for ACS.This study also supports the hypothesis that both immune and inflammation play roles in ACS.

UNLABELLED:
The patient with long history of alcohol was admitted because of intermittent right nasal bleeding for two days,and treated by nasal packing. After 3 days,the patient exhibited auditory hallucinations and immediately showed rage, mania, sweating and fever. CT examination showed calcification in the right frontal lobe, brain atrophy and sinusitis.
DIAGNOSIS
epistaxis and alcohol withdrawal syndrome, deviated septum, sinusitis.

Objective To investigate and evaluate the efficacy of elastic stable intramedullary nailing (ESIN) and bone plate set (BPS) in the treatment of femoral shaft fractures in children. Methods The study involved 39 children with femoral shaft fractures, of whom 18 children were treated with ESIN (ESIN group) and the other 21 with BPS (BPS group). In ESIN group, the nails were insert-ed through a micro incision in the medial and lateral epicondyle after closed reduction under C - arm ob-servation. In BPS group, the plates were placed on the lateral side of femur by means of open reduction and internal fixation. Results All the patients were followed up for 4-20 months (mean 10 months), which showed fracture healing in all the patients. The mean operation time, incision length, perioperative blood loss, length of hospital stay, time of fracture healing and time of weight bearing were (40.0±17.0) minutes, (2.0±0.6) cm, (30.0±8.0) ml, (7.0±1.5) days, (8.0±1.2) weeks and (6.0 ±1.0) weeks respectively in ESIN group, and (70.0±25.0) minutes, (12.0±1.1) cm, (150.0±30.0) ml, (14.0±5.2) days, (13.0±1.9) weeks and (4.0±1.3) weeks respectively in BPS group, with statistical difference between two groups (P < 0.05). Conclusions Compared with BPS, ESIN has the advantages of less operation wound, less perioperative blood loss and shorter time for fracture healing. ESIN can protect the microenvironment important for the fracture healing, and is one of ideal op-tions for treatment of femoral shaft fracture in children.
