ABSTRACT
Objective To evaluate the safety and efficacy of retroperitoneal laparoscopic procedure for rad-ical nephrectomy. Methods The clinical data of 140 cases underwent retroperitoneal aparoscopic radical nephrec-tomy from August 2013 to December 2015 were retrospectively analyzed. Among them ,87 cases were controlled by procedure for radical nephrectomy ,53 cases were treated with Non-procedural for radical nephrectomy. The peri-operative information parameters of the two groups were compared and analyzed. Results All of the 140 cases were operated under laparoscopy. There was no significant difference between the two groups in the basic condition and tumor location(P>0.05). Retroperitoneal laparoscopic procedure in the operation time ,intraoperative bleed-ing,peritoneal rupture rate,blood transfusion,complete tumor resection and postoperative drainage were better than non-procedural for radical nephrectomy ,the differences were statistically significant(P<0.01). All patients were followed up for 1 to 3 years without recurrence and metastasis. Conclusion Retroperitoneal laparoscopic pro-cedure for radical nephrectomy is significant ,worthy of clinical application and promotion.
ABSTRACT
Objective To analyze the data on hearing of recruited students from a teenager aviation school according to both the standards of PLA and those of the US Armed Forces , to learn about their differences in hearing standards in medi-cal selection, and to raise suggestions on establishing hearing standards for medical selection of flying cadets from teenager aviation schools .Methods The data collected on the first hearing test about hearing of students from Hebei Teenager Aviation School were collected .The validity of the data was determined according to the medical selection standards both of PLA and of the US Armed Forces respectively .The cases of qualified or unqualified recruits at high frequency and middle -low frequency were counted respectively and analyzed statistically .Results The unqualified recruits determined by PLA′s standards tended to be unqualified too when determined by the US Armed Forces standards .During the screening of high frequency hearing and the general hearing condition , the proportion of unqualified cases determined by the US selection standards was higher than that determined by PLA′s selection standard .In the screening of middle-low frequency hearing , no statistically significant difference was found in the proportion of unqualified cases when the two different selection standards were used.Conclusion The hearing standard for medical selection of flying cadets at high frequency in the US Armed Forces is stricter than that in the PLA .Meanwhile, the hearing standard at middle-low frequency in the US Armed Forces is different from that in the PLA , though there are no statistically significant differences in the proportion of unqualified cases.The hearing standards of the US Armed Forces are recommended in recruiting flying cadets for teenager flying schools .

ABSTRACT
Objective To discuss the synergistic mechanism of compatibility of Tripterygium Wilfordii and Astragalus,and to determine wilforlide A before and after compatibility.Methods To research Tripterygium Wilfordii single medicinal materials,Tripterygium Wilfordii compatibility of Astragalus and Tripterygium Wilfordii reference substance using the HPLC method,so as to provide further verification by the change of wilforlide A.Results The content of wilforlide A was 0.00 324% by measuring Tripterygium Wilfordii single medicinal materials.The content of wilforlide A was 0.00 184% by measuring Tripterygium Wilfordii compatibility of Astragalus.Conclusion The content of wilforlide A was decreased before and after compatibility and toxicity can be reduced.The synergistic mech-anism of the compatibility of Tripterygium Wilfordii and Astragalus is conteract the toxicity of another drugin posse.
ABSTRACT
Objective To study the content changes of wilforlide A in Xinfeng capsules before and after compatibility.Methods The content of wilforlide A was determined in Xinfeng capsules ester content and in Tripterygium wilfordii Hook.f.single solution by TLCS method.Developing solvents:chloroform and methanol (85:1),scanning wavelength:230 nm.Results Wilforlide A showed a good linear relationship in 1.700-5.100p g,the regression equation is Y =1 118.766 + 3 253.751 X (r =0.999).The average recovery of the wilforlide A in Xinfeng capsules was 102.84％,and RSD was 3.64％.The average recovery of the wilforlide A in the Tripterygium wilfordii Hook.f.single decoction was 98.14％,and RSD was 2.21％,compatibility levels before and after the change (compatibility with 0.179mg/g,0.136mg/g after compatibility).Conclusion The established TLCS method was simple,specific and accurately quantitative.The comparative study found that the compatibility of Xinfeng capsules Tripterygium reduced the content of wilforlide A,which may be related to decreasing toxicity.
ABSTRACT
Objective To detect the dynamic visual acuity ( DVA) before and after vestibular habituation of subjects in order to optimize the DVA assessment criteria .Methods The vestibular function examination system was applied to the detection of static and dynamic visual function in 16 healthy subjects .Results When the speed of left or right swinging was fast enough , DVA before and after vestibular habituation was different .Conclusion Subjects with vestibular habituation can reduce their sensitivity to the vestibular system , the changes in DVA are better than before habituation , and the vestib-ular function adaptability training may have effect on DVA .

ABSTRACT
<p><b>OBJECTIVE</b>To study the expression of phosphatase and tensin homology deleted on chromosometen ten (PTEN) protein, a tumor suppressor gene in breast cancer and its correlation with p27(kip1) and cyclin D1 expression.</p><p><b>METHODS</b>PTEN protein expression, p27(kip1) and cyclin D1 protein expression were detected by immunohistochemical method in paraffin sections from 61 women with primary breast cancer. PTEN protein expression was compared with clinico-pathologic parameters as related to p27(kip1) and cyclin D1.</p><p><b>RESULTS</b>PTEN, being shown in the cytoplasm, was negative in 6.6% (4/61), reduced in 41.0% (25/61) and positive in 52.5% (32/61) samples. PTEN expression level was correlated with axillary lymph node status, loss of estrogen receptor stain, recurrence and metastasis. On univariate analysis, the disease-free survival rate of patients with higher PTEN expression (> 50% cells stained) was better than those with lower expression (P = 0.0101). However, there was no correlation between p27(kip1), cyclin D1 expression or PTEN expression.</p><p><b>CONCLUSION</b>PTEN, its lower expression being correlated with poor outcome of breast cancer patients, plays a prominent role in breast cancer. p27(kip1) or cyclin D1 may not be the primary downstream genes of PTEN in breast cancer.</p>
