This paper deals with the inhibitory effects of Actinidia chinensis Planch (AC) on the formation of N-nitrosoproline (NPRO). In self-control studies, 15 male rats and 10 healthy men were the subjects. It was found that AC juice inhibited formation of NPRO in vivo in rats (inhibitory rate, 59.6%), and the effect was better than the same amount of a vitamin C (VC) solution (41.8%); and 150g AC fruit containing 75mg VC could completely inhibit the NPRO formation in vivo in men ingesting 300mg NaNO3 and 500mg L-proline, but 75mg VC only partially inhibited.

This paper deals with the inhibitory effect of Actinidia chinensis Planch (AC) juice on the formation of N-nitrosoproline (NPRO) in pregnant rats and women. In 21 Wistar pregnant rats and 27 pregnant women studies, it was found that NPRO formed in vivo might be transferred into the fetus, and AC juice might block it by inhibiting the NPRO formation in vivo. This was the first time to report that N-nitrosamino acid could be transferred into the fetus

Non-small cell lung cancer has a poor prognosis. Many patients who were proved to have none lymph node metastasis still relapse after operation. It may be caused by micrometastases which can′t be detected by conventional pathologic technique. Recently immunocytochemistry and moleculer methods are used to detect micrometastases in the peripheral blood, bone marrow or lymph node near the tumor. But the standard and reliable methods need to be developed and the clinical significance of micrometastases need to be discussed.

OBJECTIVETo analyze the efficacy and medication principles of Professor Xu Fu-songs traditional Chinese medicine (TCM) protocols for male diseases.

METHODSWe reviewed and descriptively analyzed the unpublished complete medical records of 100 male cases treated by Professor Xu Fu-song with his TCM protocols from 1978 to 1992.

RESULTSThe 100 cases involved 32 male diseases, most of which were difficult and complicated cases. The drug compliance was 95%. Each prescription was made up of 14 traditional Chinese drugs on average. The cure rate was 32% , and the effective rate was 85%. Professor Xu Fu-song advanced and proved some new theories and therapeutic methods.

CONCLUSIONProfessor Xu Fu-song's TCM protocols can be applied to a wide range of male diseases, mostly complicated, and are characterized by accurate differentiation of symptoms and signs, high drug compliance, and excellent therapeutic efficacy.

Objective To sum up experience with surgical excision of isolated local recurrence for renal cell carcinoma. Methods From March 2004 to November 2007, 7 patients (five cases un-derwent radical nephrectomy and two nephron-sparing surgery) with isolated local recurrence of renal cell carcinoma were treated at our department. All patients underwent extensive surgery for local re-currence. Results The mean patient age was 42 years (range 19 to 6). The mean time to local re-currence was 23.3 months (range 12 to 54). The Mean size of the recurrent tumor was 5.2 cm(range 2.5 to 10.5). Peritoneal exploration was performed in 7 patients and 5 had complete en bloc excision of the renal cell carcinoma mass. 2 patients gross disease was excised. The mean blood loss was 1050 (150-3000) ml. Surgical complications occurred in 2 patients, iliohypogastric nerve injure in one and ileus performation in another one. All patients recovered finally. Six patients were followed and one lost follow-up. Mean follow-up time was 13(8-27) months. One patient died of metastatic disease at 22 months after excision of the renal cell carcinoma mass. Conelusion En bloc excision of isolated locally recurrent renal cell carcinoma is possible, and complete surgical resection could lead to pro-longed disease-free survival.

Objectives: To evaluate the efficacy, toxicity and side effects of CAP (cytoxan, adriamycin, cisplatin), NP(navelbine, cisplatin), GP(gemcitabine, cisplatin) in the treatment of patients with non small cell Lung cancer(NSCLC). Methods:146 patients with NSCLC diagnosed by pathology or cytology were treated with CAP, GP or GP regimen. Results:The overall response rate of the three groups (CAP, NP, GP)were 33.33%, 46.43% and 47.92% respectively. The major toxicity and side effects was bone marrow inhibition and the gastrointestinal reaction. Grade Ⅲ-Ⅳ side effects of CAP group were significant higher than the others. Conclusions:The regimen of navelbine and cisplatin or gemcitabine and cisplatin was more effective and less toxic than cytoxan, adriamycin, cisplatin and cisplatin.

Protozoans,the natural host of the facultative intracellular pathogen Legionella species,play an important role in survival,proliferation,virulence and stress resistance of Legionella species. By repeating transformation and selection,a spontaneous mutant of plasmid over expressing green fluorescent protein was obtained. This mutant replicates and is maintained stably in Legionella cells. The colonies of L. pneumophila harbouring the mutated plasmid were intense green in colour even under the daylight. After feeding BF1 strain of Tetrahymena thermophila with transformed L. pneumophila,the intracellular dynamic of changing of bacterial shape,bacterial proliferation and lysis of the host cell due to the bacterial proliferation were observed clearly under fluorescent microscopy. Thus,the present paper provides a simple and intuitionistic strategy for investigating the ecological and cellular relationship between L. pneumophila and its host.

Objective To approach the protective effect of dexmedetomidine on mechanically ventilated patients with pulmonary contusion. Methods A prospective randomly controlled trial was conducted. 70 mechanically ventilated patients with pulmonary contusion from January 2010 to December 2012 in the Critical Care Medicine of Foshan Hospital of Traditional Chinese Medicine were divided into a control group and a therapy group by the difference in number odd or even,with 35 patients in each group. Based on the same principles of comprehensive treatment,the control group used midazolam,and the therapy group used dexmedetomidine for sedation. The measured parameters included oxygenation index(PaO2/FiO2),tumor necrosis factor-α(TNF-α),interleukin-6(IL-6), and extra-vacular lung water index(EVLWI)for both groups on the1st and 5th day. The incidence of delirium,the time of mechanical ventilation,and the incidence of hypotension were observed in both groups. Results Compared with those on the 1st day,TNF-α,IL-6 and EVLWI on the 5th day were decreased significantly in both groups〔the control group TNF-α(ng/L):1.29±0.38 vs. 2.21±0.37,IL-6(ng/L):97.97±28.77 vs. 131.03±41.52,EVLWI (mL/kg):8.25±2.03 vs. 11.96±3.36;the therapy group TNF-α:1.06±0.33 vs. 2.32±0.37,IL-6:82.07±23.35 vs. 134.98±64.25, EVLWI(mL/kg):6.74±1.33 vs. 11.23±2.78, all P<0.05〕, PaO2/FiO2 was increased obviously〔mmHg(1 mmHg=0.133 kPa),the control group:285.80±30.65 vs. 213.00±33.70,the therapy group:315.00±34.50 vs. 229.50±37.00,both P<0.05〕,TNF-αand IL-6 had no significant difference compared between the therapy group and control group(TNF-α:1.06±0.33 vs. 1.29±0.38,IL-6:82.07±23.35 vs. 97.97±28.77), while EVLWI and PaO2/FiO2 in the therapy group had remarkable differences compared with those of the control group〔EVLWI(mL/kg):6.74±1.33 vs. 8.25±2.03,PaO2/FiO2(mmHg):315.00±34.50 vs. 285.80±30.65,both P<0.05〕. The incidence of delirium(8.57% vs. 22.86%)and time of mechanical ventilation(day:4.10±1.09 vs. 6.88±1.66)in the therapy group were decreased markedly compared with those of the control group,and the incidence of hypotension had no significant difference between treatment or control groups(17.14% vs. 14.29%,P>0.05). Conclusion Dexmedetomidine has protective effect on mechanically ventilated patients with pulmonary contusion, and it is an relatively ideal sedative drug for these patients.
