Objective To investigate the pathological feathers,diagnosis,differential diagnosis and prognosis of esophageal granular cell tumor. Methods The data of seven patients of esophageal granular cell tumor diagnosed from 2008 to 2014 in our hospital were analyzed. Seven cases of esophageal granular cell tumor were studied by hematoxylin-eosin and EliVision immunohistochemical staining,the clinical and pathological feathers were analyzed with review of the literatures. Results The pathological feathers of seven cases were very typical. The tumors located in the submucosa,and showed gray to grayish yellow,nodular,with no capsule. The size of these tumors ranged from 0. 4 ~1. 0 cm in diameter. Microscopically,the tumor cells were round,polygonal or spindle with small central nuclei and rich eosinophilic granules cytoplasm,the nucleolus could not be easily seen. Immunohistochemical stain showed that the tumor cells were positive for S-100,CD68 and NSE,but negative for SMA,Desmin,CK,CD34,CD117,DOG1,HMB45. The proportion of Ki-67 positive cells was very low. Histochemical stain showed that the tumor cells were positive for PAS. All 7 cases were benign,and the follow-up time was from 8 months to 6 years without recurrence in patients. Conclusion Granular cell tumor of esophagus is very rare in soft tissue tumors,most of which are benign and located in the middle and lower segment of esophagus. The tumor has a better prognosis. The definite diagnosis should depend on the pathological di-agnosis.

Objective This study aimed at evaluating the safety and feasibility of transumbilical single site laparoscopic appendectomy (SSLA) by systematic review and Meta analysis of literature comparing with conventional tree-port laparoscopic appendectomy (CLA).Methods The articles published from January 2000 to December 2012 were searched from electronic databases of PubMed,Embase,and the Cochrane Library.The literature with comparative studies of SSLA with CLA for adult patients was selected.And,the systematic review and Meta analysis carried out using Stata software.Results Eleven articles with 998 cases receiving operation during March 2008 to October 2011 were enrolled into study.There were 435 cases with SSLA and 563 cases with CLA.Compared the cases with SSLA and cases with CLA,there was no difference significantly in operative time (z =1.48,P =0.140),pain score in the 24 hours after surgery (z =0.83,P =0.409),diet start(z =0.38,P =0.707),postoperative complications (z =0.46,P =0.647),hospital stay (z =0.36,P =0.722).Conclusions SSLA are not different in operative time,postoperative pain,diet start,postoperative complications,hospital time comparing with that in CLA.

Objective: To study the anti-inflamation effect of Volatile oil of Centipesa minima and the mechanism of action. Method: The “Two-hit” animal model of acute lung injury in rats was induced by oleic acid and lipopolysaccharide, to observe the protective effect of VOCM on acute lung injury in rats. Result: VOCM was able to suppress lung edema and high numbers of neutrophils, decrease the expression of CD54 in the bronchial epithelium tissue in the acute lung injury animal models. Conclusion: VOCM has a protective effect on acute lung injury in rats. Decreasing the expression of CD54 in the bronchial epithelium tissue may be one of its mechanisms of against respiratory tract inflammation.

Objective To investigate the status of living relative kidney transplantation, and the clinical effects and social significances of kidney transplantation between spouses. Methods We retrospectively collected the clinical data of the department of kidney transplant of the First Affiliated Hospital of Zhengzhou University, from January 2011 to December 2013. The spouse group as group 1, the age and sex of doners were taken into account,the siblings with the similar age of the same period were enrolled in group 2. Then the postoperative recoveries of the two groups were compared. Considering the current social status, particularly the shortage of donor kidneys, the clinical, social and family significances of kidney transplantation between spouses were analyzed. Results Twelve cases of spouses in group 1, 8 cases of siblings in group 2 , the differences of donor and recipient age of the two groups were 0.33 ± 0.98 years and 2.29 ± 7.23 years, respectively. The human major histocompatibility complex antigens (HLA) was less than three in group 1, and was greater than or equal to three in group 2. The changes of serum creatinine and urea nitrogen were analyzed. No significant differences of serum creatinine and downward trend of blood urea nitrogen were observed between two groups (P = 0.84, P = 0.79). Conclusion The kidney transplantation between spouses has good clinical efficacy and great social significance, improving the status of the shortage of donor kidney and contributing to family harmony. The renal transplantation between spouses has obvious advantages and need further promotion.

Objective To explore the demographic factors and the risk of the pedicle screw insertion of the narrow pedi?cles. Methods Thoracolumbar spine thin?section CT image data of 312 adults from September 2014 to September 2015 were ana?lyzed. The pedicle width,medial and lateral cortical thickness, spongy bone thickness, spongy bone thickness/cortical thickness, e angle and screw path length of each pedicle were measured. The incidence and the distribution characteristics of the narrow pedi?cle were analyzed. Anatomic parameters and age, gender and stature were compared between the narrow pedicle group and non?narrow pedicle. The risk of the pedicle screw insertion of the narrow pedicle was assessed. Results Among the 3 081 pedicles, 74 narrow pedicles were determined as their pedicles width were less than 5 mm, and the proportion of narrow pedicle was 2.40%. Among the 312 subjects, 26 subjects were found having narrow pedicles, and the proportion of individuals with narrow pedicles in the population was 8.33% (26/312). The incidences of narrow pedicle in thoracolumbar spine were T10 0.32%, T11 0.32%, T12 0.98%, L1 7.54%, L2 2.92%. The spongy bone thickness, spongy bone thickness/cortical thickness of narrow pedicle were lower than non?narrow pedicle. However, there were no significant differences of medial and lateral cortical thickness, e angle and screw path length between the narrow pedicle and non?narrow pedicle. Difference of the mean age between the two subjects groups had no statistical significance. The percentage of female in narrow pedicle subjects group was 84.6%(22/26), which was higher than that in non?narrow pedicle subjects group (49.7%, 142/286). The mean stature of the male and female of stenosis pedicle group subjects were 163.8±1.3 cm and 152.5±4.3 cm, which were shorter than those of non?narrow subjects pedicle group (169.5±5.6 cm, 160.1±6.6 cm). The percentage of the cortical bone breakthrough by the pedicle screws of narrow pedicle group was (84.6%, 27/32), which was higher than that of non?narrow pedicle group (14.7%, 33/224). Conclusion L1 is the most common segment of thoracolumbar spine that narrow pedicle exist, which is the result of reduction of the spongy bone thickness. Narrow pedicle mostly appears in short stature female. There is high risk of cortical bone breakthrough by insertion of the posterior pedicle screws in the narrow pedicle.

Objective To evaluate the value of high frequency color Doppler ultrasound in detecting the growth of orthotopic prostate tumor in nude mice. Methods Thirty-five orthotopic prostate tumor models of BALB/c nude mice were established. High frequency color Doppler ultrasound was used to monitor the growth of tumors in five randomly selected BALB/c nude mice after 2 - 8 weeks. After examination,the nude mice were immediately sacrificed under narcotism. The tumors were dissected, fixed and embedded. The sections were stained by HE and reviewed under microscope as the gold standard of detecting the growth of orthotopic prostate tumors. The growth curves were recorded and analyzed. Results High frequency color Doppler ultrasound can be used to observe the size, resonance, blood supply and necrosis of tumors. The tumors grew fastest in 4～6 weeks after injection. After seven weeks, necrosis can be found in the center of the tumors while the boundary of the tumor was not clear. Conclusions High frequency color Doppler ultrasound can be a reliable method to monitor the growth of orthotopic prostate tumor in BALB/c nude mice.
