Objective To evaluate the safety of CT guided percutaneous lung biopsy in the elderly,and to analyze the risk factors for its complications.Methods Totally 204 elderly patients aged ≥65 years underwent transthoracic needle biopsy under CT guidance.Clinical data,complication and its risk factors were analyzed retrospectively.Results The complications included pneumothorax accounting for 15.2% (31/204),hemoptysis 21.6% (44/204),and no mortality was found.Logistic regression analysis showed that needle path ≥5.00 cm,lesion size ≤2.00 cm and emphysema around the lesion were the independent risk factors for postoperative pneumothorax (OR=4.05,2.54 and 3.97,all P<0.05).Meanwhile,the enhancement degree by CT >40 HU,needle path ≥5.00 cm and lesion size ≤2.00 cm were the independent risk factors for postoperative bleeding (OR=2.27,2.82 and 2.33,all P<0.05) in elderly patients undergoing lung biopsy.The sensitivity and specificity for postoperative pneumothorax and bleeding obtained by forecasting equation were 87.1% and 49.1%,54.5% and 80.8% respectively.Conclusions The length of needle path,lesion size and emphysema around the lesion are correlated with pneumothroax,and length of needle path,lesion size and the CT enhancement degree are correlated with bleeding after percutaneous lung biopsy in the elderly.

Lung adenocarcinoma accounted for about 70% of non-small cell lung cancer,and now a higher risk of detected.Early diagnosis and early treatment can significantly improve lung adenocarcinoma patients after operation and improve the survival rate of patients.Bronchoscope clinical diagnosis of lung cancer and chest wall puncture in pathology has problem in that it is an operation and specimen is not easy to get,compared to tumor markers that are easy to obtain.A series of studies in recent years have shown that the joint detection of tumor markers has important value in early detection and diagnosis,prognosis assessment,and tumor recurrence of lung adenocarcinoma.

BACKGROUND:The effect of body mass index (BMI) on the outcomes ofin vitrofertilization (IVF) is controversial. Some scholars suggested that the higher BMI, the lower rate of pregnancy, and the higher rate of abortion. However, some others got the different results. To data, the effects of BMI on the pregnancy outcomes in females at different ages are rarely reported.
OBJECTIVE:To explore the effect of BMI on the pregnancy outcomes of IVF for infertile women atdifferent ages.
METHODS:A total of 902 cycles undergoing IVF were divided into two groups according to the age:≤ or> 35 years old groups. The patients in each group were then divided into four subgroups according to BMI: low weight, normal weight, excess weight, and obesity subgroups, respectively.
RESULTS AND CONCLUSION: With increasing BMI, the average dosage of gonadotropins was increased gradualy in two both of age groups (P < 0.05). In the≤ 35 years old, the levels of estrogens on the day of injecting human chorionic gonadotropin was significantly lower in obesity group than the other subgroups (P < 0.05); the rates of empty folicle in excess weight and obesity subgroups were significantly higher than that in normal weight subgroup (P < 0.008 23). The fertilization rate and clinical pregnancy rate of in obesity subgroup were significantly lower than those in the other subgroups (P < 0.05). In the > 35 years old group, the empty folicle rate in obesity subgroup was significantly higher than that in normal weight subgroup (P < 0.008 23). Fertilization rate in excess weight and obesity subgroups was significantly lower than that in the normal weight subgroup (P< 0.008 23). There were no significant differences in cleavage rate, cycle cancelation rate, implantation rate, biochemical pregnancy rate and abortion rate between four subgroups (P> 0.05). These findings suggest that in the females at the younger age, BMI not only affects the quality of folicles and fertilization rate; but with increasing BMI, clinical pregnancy rate is decreased obviously. However in the females at the older age, BMI only affects the folicular quality, embryo quality and fertilization rates; there are no significant differences in the outcomes of pregnancy in the four subgroups. BMI have effects on pregnancy outcomes of IVF, and the effects are much greater in the younger female group.

Objective To observe the antioxidative capability and the mRNA expression of sodium pump αl-subunit in kidney of hypothyroid rats by iodine deficiency and illuminate the pathogenesis of kidney damage.Methods Wistar rats were randomly divided into two groups as control group (NT) and hypothyroid group (HT).The rats were all fed with low-iodine diet derived from an endemic goiter area and drank deionized water containing different potassium iodide to duplicate hypothyriod animal models.We determined the morphometric parameters of kidney by routine histology method.The contents of malondialdehyde and free radical scavengers (GSH-PX and SOD) in kid-ney,as well as the activity of Na~+-K~+ ATPase were measured in two groups.The mRNA expression of sodium pump α1 subunit was determined by reverse transcription-polymerase chain reaction.Results Compared with that in the control group,in hypothyroid group (1) serum free T3,free T4,total T3 and total T4 were markedly lower.(2) mean glomerular area and volum diminished markedly.(3)the content of MDA and activity of PGx increased markedly,but the activity of SOD decreased significantly,as well as the one of Na~+-K~+-ATPase.(4)the mRNA expression level of sodium pump α1 subunit was lower.Conclusion In a hypothyroid state,the decrease of antiox-idative capability of kidney resulted in lipid peroxidative damage,atrophy of kidney,decreased activity of Na~+-K~+ -ATPase and degression of sodium pump α1 subunit mRNA expression.

Objective To summarize the experiences in clinical diagnosis and surgical treatment of chest cancers invading the superior vena cava (SVC). Method Retrospective study of 12 cases with chest cancers invading the SVC, SVC and innominate vein were reconstructed with prosthesis in 3 cases, the side wall of the SVC was excised and repaired in 9 cases. Results Complete resection was performed in 10cases,2 cases had incomplete resection. There was no death associated with operation in these patients. All patients were followed up for 1 - 7 years after operation,and 3 cases were lost to follow up,5 of remaining 9cases were dead because of relapse and metastasis, their median survival time was 8 months,other 4 cases lived, their median survival time was 42 months. Conclusions Patients with chest cancers invading the SVC should have surgical treatment of not only tumor resection but also the vessel reconstruction,the prognosis would be better than without surgical treatment. These patients have a high quality of life and live with long-term survival.

High-fat diet-induced insulin resistance rat model was assessed by euglycemic-hyperinsulinemic clamp technique.Compared with the control group,the vaspin mRNA expression in adipose tissue was significantly decreased in insulin resistant rats induced by high-fat diet( P<0.05 ),which was increased by metformin( P<0.05 ).These data indicate that metformin may ameliorate insulin resistance in rats via upregulating vaspin mRNA expression.

Objective To evaluate the methods of standard patient (SP)combined with case-based learning (CBL ) in humanistic quality cultivation for interns in the department of thoracic surgery. Methods Medical interns in the department of thoracic surgery were divided randomly into experimental(n=30)and control group(n=30)respectively. In experimental group,SP combined with CBL was used while in control group traditional teaching was used. At the end of the study,teaching effect was assessed by the final examination and questionnaires and the data were processed by t test andX2 test. P<0.05 signifies statistical differences. Results There was no significant difference in test scores between the two groups (P>0.05). Scores of history-taking,medical check-up,paper writing quality in the final examination in experimental group were significantly higher than those in control group(P<0.01). Satisfaction degrees of doctor-patient communication,responsibility and service attitude in experimental group were better than those of control group(X2=16.484,10.335,20.376,32.851,P<0.01). Conclusions SP combined with CBL teaching method can stimulate the students' interests in thoracic surgery practice,improve the doctor-patient relationship and strengthen the ability of human-istic concern. It is a better clinical thoracic practice teaching method and it is beneficial to cultivating medical students with humanistic concern.
