OBJECTIVETo investigate the prevalence of malignant tumor and its influencing factor among rubber workers in Hainan Province of China, and to study the high incidence of cancer and type of work.

METHODSA retrospective cohort study on registered workers over 1 working age among partial rubber factories in Hainan Province in the period from 2005 to 2010.

RESULTThere was a remarkable difference in the incidence between nature exposed rubber group and non-exposed group (χ(2) = 52.13,P < 0.01). Occupational exposure induced a high risk in malignant tumors (OR = 2.47, P < 0.05). The incidence of tumor may be associated with occupational exposure: the longer occupational exposure time, the higher was the incidence of tumor (χ(2) = 11.40, P < 0.05).

CONCLUSIONSThe occupational exposure in rubber workers can induce a high incidence of malignant tumor.

The present study aims to investigate the kinetic histocytochemical changes of acupoints in different condition. The expression of tryptase (+) mast cells, histamine (HA) , serotonin (5-HT) and nociceptive neuropeptides including calcitonin gene-related peptide (CGRP) and substance P (SP) were observed by immunohistochemistry combined with confocal technology. Mast cells were labeled with anti-mast cell tryptase antibody and simultaneously with HA or 5-HT primary antibodies to observe their co-expression. The results showed that: (1) SP and CGRP were expressed more highly on the cutaneous nerve fibers of "Hegu" (LI 4) after acupuncture stimulation than that of the control. Mast cells aggregated in close proximity to the blood vessels in intra-epidermis and dermis, and some of them with degranulation in the lower dermis and subcutaneous tissue of "Hegu" (LI 4). Both mast cells and their granules appeared with HA (+) and 5-HT (+) expression at stimulated LI 4 sites, while a few intact mast cells with a little expression of 5-HT and HA were distributed in areas of non-stimulated Ll 4. (2) The acupoints in different locations such as Baihui (GV 20), Weishu (BL 21), Zhongwan (CV 12) and LI 4 had the same constituent but the contents were different. (3) The histocytochemical responses of acupoints sensitized by the Gastric mucosa injury (GMI) were also investigated. GMI resulted in neurogenic plasma extravasation by Evans Blue (EB) in the skin of the acupoints over the back and abdomen, which mostly occurred in the T9-T11 dermatomere. The EB extravasation dots just like acupoints sensitization appeared after GMI and disappeared gradually during the natural self-recovery of the gastric mucosa. More SP and CGRP positive nerve fibers were distributed in EB dots than in regions beside EB dots and in the control, mostly distributed in the nerve fibers around both the vessels and root of hair follicle. Mast cells also aggregated and degranulated to release algogenic substances of 5-HT and HA around the vessels in areas of the EB dots. Collectively the acupoints displayed the same histocytochemical responses due to either acupuncture stimulation or GMI. This may potentially be the histocytochemical basis in the local acupoints and acupoints displayed kinetic changes in different condition.

Objective To evaluate the treatment effect of negative pressure wound therapy ( NPWT) followed by ultrasonic debridement surgical system ( UDSS) in patients with diabetic foot. Methods Forty-seven diabetic foot ulcer patients( WagnerⅡ~Ⅲ) were divided into two groups,of which 26 patients treated with UDSS combined NPWT,and 21 patients treated with traditional surgical debridement combined NPWT were control group. Cure rate, markedly effective rate and adverse reaction and complication were compared between two groups. Results Compared with control group,the experiment group had higher markedly effective rate in the first week(P<0. 05),and healing rates were higher in the 2th,4th,6th,12th weeks (P<0. 05). There were no differences in the adverse reactions and complications between the two groups. Conclusion UDSS combined with NPWT can accelerate wound cure,may play an important role for the treatment of diabetic foot ulcer.

Objective To investigate the therapeutic effect of different methods of dressing on the wound after local debridement of dia-betic foot. Methods A total of 53 patients which underwent local debridement of diabetic foot were divided into control group and treatment group. Patients in control group were dressed on traditional measurement,while patients in the treatment group were dressed on the external medicinal wine for the diabetic foot basic on the traditional treatment. The local transcutaneous oxygen partial pressure,ulcer healing rate,av-erage healing time and the amputation rate were observed. Results The healing rate and percutaneous oxygen partial pressure of the treat-ment group were significantly increased than those in the control group (P<0. 05). The average healing time and amputation rate of the treat-ment group were significantly less than those in the control group (P<0. 05). Conclusion Dressing on external medicinal wine after local debridement of diabetic foot can improve the wound healing in the diabetic foot.

Objective Labial gland biopsy is one of major diagnostic methods for Sj(o)gren's syn-drome(SS).Meanwhile,99TcmO-4 parotid scintigraphy has been proven useful for the clinical evaluation of SS.This study was performed to investigate the correlation between the two examinations and evaluate the semi-quantitative parotid scintigraphy in the early diagnosis and staging for SS patients.Methods There were 135 SS patients and 30 normal subjects as control group in this study.They all underwent 99TcmO-4 pa-rotid scintigraphy.Semi-quantitative analyses of parotid scintigraphy were conducted with parameters inclu-ding maximum accumulation ratio (MAR),maximum secretion ratio(MSR),time interval from stimulation to minimum count(tparotid),prestimulatory oral activity index (PRI) and poststimulatory oral activity index (POI).For comparison, the biopsy of labial gland was performed in each patient and the pathological se-verity was classified into grade 0,1,2,3,4 (also defined as subgroups).One-way ANOVA and q-teat were applied for the correlation analyses between the two examinations.Results There was significant difference between pathological subgroup 3 or subgroup 4 and the control in all the semi-quantitative parame-ters (q=6.79-38.64,P<0.O1).In subgroups 1 and 2,only PRI and POI showed significant changes compared with the control(q=8.33,8.63,all P<0.01).The pathological stages were negatively correla-ted with MAR(r=-0.679,P<0.01),MSR(r=-0.601,P<0.01),PRI(r=-0.724,P<0.01)and POI(r=-0.751,P<0.01),but only positively correlated with tparotid(r=0.364,P<0.01).Con-clusions Most semi-quantitative parameters of 99TcmaO-4 parotid scintigraphy may be well correlated with the pathological severity of labial gland biopsy in SS patients.Further,the semi-quantitative indices espe-eially PRI and POI may be helpful for the early diagnosis and staging of SS patients.

Objective To observe the efficacy and adverse reaction of ozone therapy combined with gemcitabine and cisplatin (GP) regimen in patients with advanced non-small cell lung cancer.Methods Fifty-five patients with advanced non-small cell lung cancer were enrolled and allocated to treatment group (28 cases) and control group (27 cases).The patients in treatment group received ozone therapy combined with GP regimen,and the patients in control group received GP regimen only.The efficacy,quality of life,adverse reaction and cellular immune function after treatment was compared between two groups.Results There was no significant difference in the efficacy between two groups (P ＞ 0.05).The quality of life after treatment in treatment group was better than that in control group (P ＜ 0.05).The liver function damage in treatment group was lower than that in control group (P ＜ 0.05).The cellular immune function in treatment group was stronger than that in control group (P ＜ 0.05).Conclusion Ozone therapy combined with GP regimen can effectively alleviate adverse induced by GP regimen chemotherapy and significantly improve the quality of life in patients with advanced non-small cell lung cancer.
