Objective To evaluate the therapeutic efficacy of neoadjuvant chemotherapy in cervical carcinoma. Methods TAC(DDP, EPI and BLM) was applied in 68 patients with cervical carcinoma. Therapeutic efficacy and side effects were documented. Results After 1～3 cycles of neoadjuvant chemotherapy, clinical symptoms remission rares reached 100% ,response rate were 100% (40/40) in Ⅰ b～Ⅱ a,90.9% (20/22) in Ⅱ b and 50% (2/4)in Ⅲ a, respectively. Radical resection reached 91.2 %, and only 6 patients of advanced disease failed to radical resection and turned to radiotherapy. Conclusion Neoadjuvant chemotherapy is a safe and effective therapeutic option which could alleviate clinical symptoms, decrease tumor size, down-staging and increase the radical resection rate.

Epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) is a kind of targeted drug for the treatment of non-small cell lung cancer (NSCLC),but almost all patients develop EGFR-TKI resistance.In Chinese medicine,it is believed that Yang deficiency is the leading cause of tumor,which could end up with the internal formation of cancer toxin and promote the formation of tangible excess pathogens.Clinical and experimental studies have shown that the Chinese medicine treatment based on Yang-warming method can inhibit EGFR-TKI resistance and improve the therapeutic effect of EGFR-TKI.The mechanism may be related to the regulation of miRNA gene and estrogen receptor expression,being against tumor heterogeneity and the regulation of tumor microenvironment.Therefore,Yang deficiency is the key pathogenesis of the EGFR-TKI resistance in NSCLC,and the method reinforcing Yang and suppressing Yin is the basic therapeutic way in Chinese medicine to overcome EGFR-TKI resistance.

Objective To observe the parameters and effect of endocardial pacing by steel wire electrode cardiac puncture on heart with normal beat in living animal, and evaluate its safety.Methods After anaesthesia and thoracotomy in 6 living dogs with normal heart beat, the pericardia were excised. Steel wire electrodes with annular or hook tips were used respectively at right ventricular 4 corresponding spots to perform cardiac puncture endocardiac pacing (each dog experienced 8 times of puncture); the time from puncture to effective pacing, pacing parameter and puncture complication (time and quantity of bleeding) of each electrode at each spot were recorded. Finally, the two types of electrode completed 24 times of manipulation respectively; the data collected of the two types were compared. Results The cardiac pacing successful rates in the two groups were 100%; the time taken from the beginning of heart puncture to effective pacing in annular tip group was less than that in hook tip group, but the time difference between the two groups showed no statistical significance (s: 18.4±2.3 vs. 19.6±4.1,P > 0.05). The parameters of pacing in the annular tip group, such as operation time (s: 18.4±2.3 vs. 19.6±4.1), the threshold value of pacing (V: 2.1±0.2 vs. 2.2±0.8), the amplitude of R wave sensed (mV: 11.3±3.2 vs. 12.6±4.1) and the impedance of electrode (Ω: 674.2±89.7 vs. 668.5±101.3) were not significantly different compared with those in the hook tip group (allP > 0.05). Either after puncture or after the electrodes were taken out, the time of bleeding [after puncture (minutes): 4.4±2.3 vs. 4.5±3.1, after the electrodes taken out (minutes): 4.1±2.2 vs. 4.8±2.5] and the volume of bleeding [after puncture (mL): 2.8±2.4 vs. 3.2±3.5, after the electrodes taken out (mL): 3.3±1.7 vs. 3.5±2.6] were not significantly different between the two groups (allP > 0.05).Conclusions In living dogs with normal heart beat, the manipulation and function of endocardiac pacing by cardiac puncture with either steel wire annular or hook tip electrode are well and effective, and the performance is simple and safe without any serious myocardial injury and complication. Thus, it is helpful to quickly establish efficient endocardiac pacing in emergency cases.

OBJECTIVETo compare the effect and impact of holmium laser enucleation of the prostate (HoLEP) and 120-W thulium: YAG vapoenucleation of the prostate (ThuVEP) on erectile function in the treatment of benign prostatic hyperplasia (BPH).

METHODSWe retrospectively analyzed 93 cases of symptomatic BPH treated by HoLEP or 120 W ThuVEP. We made comparisons between the two groups of patients in the baseline and postoperative clinical and surgical indexes as well as their IPSS, quality of life (QOL), maximum flow rate (Qmax), postvoid residual urine volume (PVR), and IIEF-EF scores before surgery and during the 12-month follow-up.

RESULTSThuVEP, in comparison with HoLEP, achieved a significantly shorter operation time ([57.6 +/- 12. 8] vs. [70.4 +/- 21.8] min, P = 0.001) and a higher laser efficiency ([0.71 +/- 0.18] vs. [0.62 +/- 0.19] g/min, P = 0. 021). At 1, 6, or 12 months of follow-up, no significant differences were observed in IPSS, OOL, Omax, and PVR between the two groups (P > 0.05). Both the HoLEP and ThuVEP groups showed low incidences of complications and remarkably improved IIEF-EF scores at 12 months postoperatively, but with no significant differences (both P > 0.05). However, in those with relatively normal erectile functions before operation, the mean IIEF-EF score was reduced from 22.8 +/- 2.2 preoperatively to 21.0 +/- 2.7 after HoLEP, (P = 0.036).

CONCLUSIONBoth HoLEP and 120W ThuVEP are effective and safe in the treatment of BPH. Compared with HoLEP, 120 W ThuVEP has even a higher laser efficiency. However, neither can significantly improve erectile function, and HoLEP may have a short-term negative impact on the relatively normal erectile function of the patient.

OBJECTIVETo verify the pharmacological hypothesis of prescriptions by studying the targeted distribution of major components in stewed rhubarb in the rat model with acute pancreatitis (AP).

METHODNormal SD rats (control group, n = 5) and the AP model induced with intraperitoneal cerulein (model group, n = 5) were taken as the experimental objects. Rats of the two groups were orally administered with stewed rhubarb granules (20 g x kg(-1)). Their heart, liver, spleen, lung, kidney and pancreas were collected two hours after the administration. Such constituents as emodin, chrysophanol, physcion, rhein and aloe-emodin and their concentrations in each tissue homogenate were detected by high performance liquid chromatography-mass-mass.

RESULTAloe-emodin and physcion in stewed rhubarb whose concentrations in liver and kidney of normal rats were higher than that in pancreatic tissues, while the distribution spectrums and concentrations of the remaining components in pancreatic tissues had no significant difference with that of other organs. The concentrations of emodin, aloe-emodin, rhein and chrysophanol in stewed rhubarb in pancreatic tissues of the AP model group were higher than that in other tissues and organs, while their concentrations in pancreatic, renal and splenic tissues were notably higher than that in the normal group.

CONCLUSIONIn the conditions of AP, effective components in stewed rhubarb show a targeted distribution feature in pancreas, which provides experimental basis for the pharmacological hypothesis of prescriptions.

Objective The risk for coronary artery bypass surgery is reported to be increased with age and associated with diabetes. We examined the outcomes of coronary artery bypass grafting (CABG) in patients with diabetes who were older than 70 years of age and evaluate the effect of diabetes on CABG in those patients. Methods From March 2000 to March 2008, the data of 649 patients older than 70 years of age were collected retrospectively and divided into diabetic group or non-diabetic group based on pre-operative diagnosis. The blood glucose level of patients was maintained between 7.0 mmol/L ( 126mg/dl) and 10.0 mmoL/L ( 180 mg/dl) porioporatively. Stats 7.0 was used for statistical analysis. The t test and χ~2 test were used to determine the differences in the numerical variables and categorical variables respectively. Results No statistical differences were observed between the two groups in the baseline variables, such as age [ ( 74.78±3.67 ) years for diabetic group vs. ( 75.00±3.65 ) years for non-diabetic group, P = 0. 4877 ], female patients ( 34.76% vs. 29.22%, P =0. 1663 ), ejection fraction [ ( 57.02±10. 10 ) % vs. ( 58.49±10. 39 ) %, P = 0. 1004 ) ], myocardial infarction history (26.20% vs. 28.35%, P =0. 5795), though there were more left main diseases in the diabetic group (52.41% vs.26.41%, diabetic vs. non-diabetic, P = 0. 0000 ). The overall in-hospital mortality was 6.32% (8.02% in the diabetic group vs. 5.63% in the non-diabetic group, P = 0. 2571 ). The main causes of death were sudden respiratory and cardiac arrest,low cardiac output syndrome ( LCOS), malignant arrhythmia, respiratory failure, renal failure, central nervous system compli-cations, and multiple organ failure. Major post-operative complications were bleeding, atrial fibrillation, plural effusion and pulmonary infection. Post-operative variables, such as EF (0.59±0. 13 in the diabetic group vs. 0. 61±0.15 in the non-dia-betie group, P =0. 1807), re-revascularization due to bleeding (2. 14% vs. 4.76%, P = 0. 1232), blood transfusion (89.84% vs. 84.63%, P = 0.0820) and the administration of vasoactive agent (21.93% vs. 27.71%, P= 0. 1286),were found no significant difference between the two groups. Conclusion Conclusions The early outcomes of CABG in aged patients are acceptable. The surgical consequences in diabetic patients may be similar to those in non-diabetic patients.
