Purpose:To study the change of serum vascular endothelial growth factor (VEGF) level before and after radiotherapy in patients with nasopharyngeal carcinoma(NPC) ,esophageal /lung carcinoma and postoperative brain tumor ,and to evaluate its clinical significance. Methods:serum VEGF level was measured by sandwich ELISA in 86 cancer patients and 24 healthy individuals. Results:The serum VEGF levels (?s,pg/ml) in cancer patients were 207.5?168.5 which were significantly higher than those of healthy subjects(134.1 ?s 66.6,P

Objective To evaluate the advantages and disadvantages of different puncture positions in percutaneous nephrolithotomy. Methods Three hundred fifty-six patients who underwent PCNL were analyzed from March 2012 to October 2015. The passage caliber was 16F-20F. There were 217 cases in prone position and 139 cases in supine position. Results The successful operation in PCNL was 354 cases , while the remaining 2 cases were performed by open surgery. The primary stone clearance rate was 75.5%. The additional PCNLs were performed in 23 cases, and 63 cases of residual calculi were treated by ESWL. 11 patients were treated due to infection or bleeding by the additional PCNLs. There were 3 cases with massive hemorrhage which were treated by Interventional embolization therapy , 12 cases in postoperative fever , no renal resection , no intestinal injury, no deaths. There was no significant difference in stone clearance rate and complication rate between the two groups. Conclusion The puncture position of PCNL can be optional based on the stone size , stone location, degree of hydronephrosis ,and patient′s cardiopulmonary condition individually.

OBJECTIVETo observe the effect differences on post-stroke dysphagia among acupoint injection combined with neural electrical stimulation, acupoint injection, neural electrical stimulation, and swallowing training respectively, so eligible intervention can be applied to this kind of disease.

METHODSOne hundred and eight-three patients of post-stroke dysphagia were randomized into a comprehensive treatment group (42 cases), an acupoint injection group (44 cases), a neural electrical stimulation group (49 cases) and a swallow training group (48 cases) and were treated with the comprehensive therapy of acupoint injection and neural electrical stimulation, acupoint injection, neural electrical stimulation and swallowing training separately. The treatments for 10 days made one session. There were 3 days at the interval among treatment sessions and 3 sessions were required totally. The cases in those treatment groups were blankly controlled with the other 47 patients of post-stroke dysphagia. All the patients received basic rehabilitation treatment. The modified water swallowing test was conducted to assess the efficacy before treatment, 10 days after treatment and 30 days after treatment in each group separately. The clinical efficacy, score of water swallowing test and improvement in water swallow test were compared among the groups.

RESULTSAfter 10-day treatment, the differences in efficacy and score of water swallow test were not significant in each group (all P > 0.05). After 30-day treatment, the effective rate (94.29%, 33/35) in the comprehensive treatment group was apparently better than 68.75% (22/32) in the acupoint injection group, 80.00% (32/40) in the neural electrical stimulation group, 67.50% (27/40) in the swallowing training group and 42.86% (12/28) in the blank group separately. The score in water swallow test in the comprehensive treatment group was lower than that in each of the other groups (1.37 ± 0.60 vs 2.03 ± 1.00, 1.90 ± 0.90, 2.20 ± 0.72, 2.71 ± 0.90, all P < 0.05). The differences in the effective rate and score in water swallow test were not significant among the acupoint injection group, neural electrical stimulation group and swallowing training group (all P > 0.05), which indicated that the improvement in swallowing function in the comprehensive treatment group was significantly superior to the other groups (all P < 0.05).

CONCLUSIONThe comprehensive therapy of acupoint injection and neural electrical stimulation achieves the much better efficacy on post-stroke dysphagia.

Objective To investigate the effect of sumical resection in the management of gestafional trophoblastic neoplasia(GTN)patients with pulmonary metastases.Methods A retrospective review of the medical records of 62 GTN patients who underwent pulmonary resection was carried out.The cases were divided into recurrent group(group A,,l=10),drug-resistant group(group B,n=28),and the group with satisfactory response to chemotherapy but residual pulmonary lesion(s)(group C,n=25).One patient underwent lobectomy twice,and she was allocated simultaneously to groups A and B.The patients'median age,antecedent pregnancy,International Federation of Gynecology and Obstetrics(NGO)risk score,number of preoperative chemotherapy courses,preoperative β-human chorionic gonadotrophin (β-hCG)titer,lesion size,number of lobes affected,positive rate of histology,follow-ups and prognosis were compared between the three groups.Results The proportion of hish-risk patients in the three groups wag 90%,82%and 44%,respectively.The complete remission rates of the three groups were 90%,79%and 100%,with relapse mtes of 2/8,15%and zero,respectively.Positive histology of the resected specimen wasmore frequently recognized in recurrent and drug-resistant groups(A 60%,B 36%,C 12%).In the drug-resistant group there were more preoperative chemotherapy 8essiorls(A 3,B 7,C 5)and more patients with abnormal preoperative B-hCG titer(A 50%,B 61%,C 12%).Conclusions Surgical resection is effective in the treatment of pulmonary metastases of GTN.Surgery is indicated when clinical evidence suggests that pulmonary metastatic disease causes relapse or drug—resistance and the lesions are relatively localized.Surgical resection is not recommended for patients with satisfactory response to chemotherapy but residual pulmonary lesions.

Objective To analyze prophylactic chemotherapy outcome and clinical characteristics in patients of high-risk hydatidiform mole. Methods Twenty-three patients who were diagnosed as high-risk hydatidiform mole and undergone prophylactic chemotherapy in our hospital were retrospectively analyzed.After prophylactic chemotherapy, 11 patients didn't develop to gestational trophoblastic neoplasia (GTN),while the other 12 patients developed to GTN and needed a regimen change to combination chemotherapy.The clinical characteristics of these patients and outcome of prophylactic chemotherapy were compared between two groups. Results There was no significant difference between the two groups on patients' age,weeks of delayed menses, enlarged uterine size excessive for gestational age, and incidence of theca-lutein cysts of ovaries. However,the median levels of pre-evacuation serum β-hCG in two groups were 469 144 U/L and 768 044 U/L respectively, and median days needed for β-hCG declining to normal(≤2U/L) at the first time were 71 and 120 days respectively, which were both significantly different between two groups.Analyzed with receiver operating charactristic(ROC), the level of serum β-hCG could be a predictor for prognosis. Choosing 750 000 U/L as the cut-off value, we could expect the serum β-hCG to have a specificity of 91% and a sensitivity of 58% to predict whether prophylactic chemotherapy will be successful.Conclusions For those patients who have to receive prophylactic chemotherapy because of risk factors and unavailable hCG assessments for follow-up, it's better to use double-agent or combination chemotherapy if the level of serum β-hCG reached 750 000 U/L so as to reduce therapy duration and prevent relevant chemoresistance.

Objective To analyze and compare the clinical characteristics and the treatment outcome of the patients with chemo-resistant and relapsed gestational trophoblastic neoplasia (GTN).Methods The clinical records of the patients with refractory GTN treated at the Peking Union Medical College Hospital (PUMCH) from Jan 2005 to Dec 2007 were retrospectively reviewed.According to the reasons for referral, all cases were classified as chemo-resistant GTN group who had never a normal serum human chorionic gonadotropin-beta subunit (β-hCG) level during their previous treatment, relapsed GTN group who had elevated serum β-hCG levels in the absence of the pregnancy after finished treatment 3 months or more, and undetermined GTN group who had elevated serum β-hCG levels in the absence of the pregnancy less than 3 months after completed treatment.The clinical features and treatment outcomes were compared between undetermined GTN group and chemo-resistant GTN group and also between undetermined GTN group and relapsed GTN group, respectively.Results Of 81 patients with refractory GTN, 32 cases were defined as undetermined GTN, 38 cases as chemo-resistant GTN and 11 cases as relapsed GTN.The median number of previous chemotherapy regimens, the rate of serologic complete remission ( SCR), the patients who needed to change regimens due to resistance, and the patients who needed to change regimens in the undetermined GTN group and the chemo-resistant GTN group were 2.3 versus 3.1 ( P = 0.010),100% (32/32) versus 66% (25/38, P ＜ 0.01 ), 22% (7/32) versus 58% (22/38, P = 0.002) and 28% (9/32) versus 63% (24/38, P = 0.003 ), respectively.No significant difference were observed between undetermined GTN group and relapsed GTN group in clinical features, previous and current treatment or treatment outcome ( all P ＞0.05 ).Conclusions In order to evaluate accurately the treatment outcome of refractory GTN, it seems more appropriate for the patients who had reached the normal value of serum β-hCG when completed treatment to be defined as patients with relapsed GTN, while whose serum β-hCG levels elevated in the absence of the pregnancy after the completion of treatment, irrespectively of duration of stopping treatment.Comparing with the patients with chemo-resistant GTN, the outcome of patients with relapsed GTN is better.

Objective To investigate the effects of 20% lipid emulsion on plasma ropivacaine concentration and myocardial ropivacaine content in rats. Methods Sixty male pathogen-free SD rats weighing 220-270 g were randomly divided into 2 groups (n = 30 each): group A normal saline and group B lipid emulsion.The animals were anesthetized with intraperitoneal 4% pentobarbital 40 mg/kg. The femoral vein was cannulated for drug and fluid administration. ECG (lead Ⅱ) was continuously monitored. 1% ropivacainc 5 mg/kg was injected iv. A bolus of 20% lipid emulsion 5 ml/kg was then injected iv in group B, while in group A equal volume of normal saline was administered instead of 20% lipid emulsion. The animals were sacrificed at 5, 10,20, 40, 60 and 120 min after ropivacaine infusion (5 animals at each time point). Blood samples and myocardial specimens were taken for determination of plasma and myocardial ropivacaine levels by HPLC. Results Plasma ropivacaine concentration at 20 min after ropivacaine administration was significantly higher in group B than in group A. The myocardial ropivacaine concents at 5, 10 min after ropivacaine administration were significantly lower in group B than in group A. Conclusion 20% lipid emulsion infusion can bind ropivacaine and decreasee myocardial ropivacaine content thus reducing the cardiac toxicity of ropivacaine.
