Objective To observe the clinical efficacy of medicinal moxibustion plus oral administration of Chinese medication in treating chronic eczema.Method Seventy patients with chronic eczema were randomized into a treatment group and a control group, 35 cases in each group. The treatment group was intervened by medicinal moxibustion plus oral administration of Chinese medication, while the control group was by conventional moxibustion plus Chinese medication. The Scoring Atopic Dermatitis Index (SCORAD) was observed before and after treatment, and the clinical efficacies were compared.Result The total effective rate was 72.7% in the treatment group versus 56.3% in the control group, and the difference was statistically significant (P<0.05). The SCORAD scores were significantly changed after treatment in both groups (P<0.05). After treatment, the SCORAD score of the treatment group was significantly different from that of the control group (P<0.05).Conclusion Medicinal moxibustion plus oral administration of Chinese medication is an effective method in treating chronic eczema.

0.05).During unilateral contact maximal biting EMG activity of the temporalis-anterior muscle on the bitting-side was higher than that on the disoccluded side(P0.05).Conclusion: Vertical distance occlusion contact may affect the EMG activity of temporalis-anterior muscle but not on that of masseter muscle during the central biting.

Objective To approach the reasons and influence factors about sudden deafness of nurs-es in the operating room. Methods We investigated the psychologic status and etiological factors of nurs-es in operating room through questionnaires designed by ourselves about general work pressure and sudden deafness correlative reasons. Results The total score of pressure was 21.486,among which rush work and check and examination,worrying about mistakes and accidents, pricking wound were the main reasons re-suiting in sudden deafness for the operating room nurses. Conclusions Enhancement of psychological nursing, health education and working environment improvement can lessen the anxiety emotion of nurses who have sudden deafness and has considerable effect to promote recovery.

Objective To summarize the key point of application of acellular dermal matrix(ADM)in operative cooperation of pharyngeal tissue repair.Methods In order to rebuild the air-tight cavity,ADM was sewn to the anterior vertebrae fascia in 7 patients with pharyngeal malignant tumor undergoing total laryngectomy or pharyngolaryngectomy to rebuild the posterior wall of the laryngopharynx.Meanwhile the muscular flap of the pectoralis major Was used to rebuild the anterior and lateral walls of the laryngopharynx.Results There was no reject reaction or pharyngeal fistula in these 7 cases and the wound surface were all mucous membranized.All the incisions reached the primary healing.Conclusions ADM is easy to get and possesses good histocompatibility and compatible thickness.It is easy to be managed during operation and can modify the peripharyngeal defect with the combination of muscular flap of the pectoralis major or any other neck tissue.Strict nursing preparation before operation and perfect cooperation during operation are key steps to complete the surgery successfully.

Objective To explore the effect of the self-designed cotton-padded covering for a modified lithotomy position on preventing complications in the lower limbs in patients undergoing gynecological laparscopic surgery.Methods A total of 320 patients undergoing radical hysterectomy or deep invasive endometriosis were selected and randomly divided into an observation group(n=160) and a control group(n=160).The patients in the control group were placed on the routine lithotomy position,the lower extremity and popliteal space protected with oasis outline cushion in the control group,while the patients in the observation group were placed on the same pads,the lower extremity and popliteal space protected with the self-designed cotton-padded coverings.Results The average temperature of the lower limbs of patients after operation in the observation group was significantly higher than that in the control group (P<0.01).The incidences of complications in the observation group were significantly lower than those in the control group(all P<0.05). Conclusion The self-designed cotton-padded covering for modified lithotomy position can effectively prevent the complications of the lower limbs and improve the comfort of patients.

Objective:To analyze the dental and mandibular asymmetry of adults with Class Ⅱ subdivision malocclusion.Methods:The jaw bones of 30 adults with Class Ⅱ subdivision malocclusion(case group)and 30 with normal-occlusion(control group)were scanned by CBCT.Linear and angular comparison was conducted between the two groups.Results:Dental midline deviation was ob-served in case group,mostly in mandibular arch (60%).The development of Class Ⅱ molar relationship correlated mainly to distally positioned mandibular molar on Class Ⅱ side.Conclusion:In the adults with Class Ⅱ subdvision malocclusion odontogenic asymme-try is the major factor,bony asymmetry is the miner.

Objective To compare the results and safety between video-assisted thoracoscopic surgery ( VATS ) and conventional radical operation in patients with stage Ⅰ , Ⅱ esophageal cancer. Methods Retrospectively reviewed 43 patients with stage Ⅰ , Ⅱ esophageal cancer,underwent either VATS radical operation (VATS group,16 cases) or conventional radical operation (control group,27 cases ) from September 2007 to September 2009. Patient's operative characteristics and postoperative courses were compared between two groups. Results In VATS group the operation time was ( 115.6 ± 48.0) min,the peri-operative blood loss was ( 131 ± 71 ) ml,the first postoperative day chest lead quantity was (331 ± 170)ml, the time of postoperative chest tube was (7.25 ± 2.35) d,the postoperative 36 h visual analogue scale (VAS) was (3.4 ± 1.2) scores,the postoperative drainage of chest was ( 1281 ± 534) ml,the 72 h postoperative locomotor activity of right upper extremity was (5.1 ± 1.5) cm. While in control group was ( 145.6 ± 20.6)min, (292 ± 111 ) ml, (494 ± 194) ml, ( 10.00 ± 2.79 )d, (7.3 ± 1.4) scores, ( 1780 ± 731 ) ml, ( 15.6 ± 3.1 )cm respectively (P ＜ 0.01 or ＜ 0.05 ). The lymph node dissection number,the total cost of hospital between were no statistically significant differences in two groups (P ＞0.05). Conclusion Comparing with conventional radical operation, VATS radical operation for patients with stage Ⅰ , Ⅱ esophageal cancer appears to be as effective but less morbid.

Objective:To analyse the asymmetry of mandibular of adults with skeletal classⅢmalocclusion and mandibular deviation using cone-beam computerized tomography(CBCT).Methods:20 adults with skeletal classⅢmalocclusion and mandibular deviation (deviation group)and 20 adults with individual normal occlusion(normal group)were included.CBCT slices were taken for each sub-ject.INVIVO 5 software was used to make 3D reconstruction and location marks for line distance and volume measurements of mandi-ble and condyle.Results:The measurements of the mandibular ramus length,mandibular total length,hemi-mandibular volume, mandibular ramus volume,posterior part of mandibular body length,condylar unit length,angular unit length,body unit length and an-gular angle in deviation group were significantly different between 2 sides(P<0.05).Compared with the normal group,differences of the asymmetry of mandibular ramus length,mandibular total length,hemi-mandibular volume,mandibular ramus volume,posterior part of mandibular body length,angular angle,condylar unit length and body unit length between 2 sides in deviation group were sig-nificantly different(P<0.05).Conclusion:In adults with skeletal classⅢmalocclusion and mandibular deviation deviated condylar and mandibular ramus are smaller than those of the nondeviated;the posterior part of mandibular body is slightly asymmetric while the anterior part of mandibular body is almost symmetric.

Background Conjunctivochalasis (CCh) is a common age-related ocular surface diseases.Researches showed that the inflammatory factors are upregulated in conjunctiva and tear of CCh patients,inferring inflammation participates in the pathogenesis of CCh,however,its mechanism is unclear now.Studies also showed that the expression of matrix metalloproteinases (MMPs) in CCh conjunctiva is elevated.However,the association between inflammatory factors and MMPs is unknown.Objective This research was to observe the effects of tumor necrosisfactor-α (TNF-α) and interleukin-1 β (IL-1 β) on the expression of MMP-1,MMP-3,tumor necrosis factor-stimulatedgene-6(TSG-6) and pentraxin-3 (PTX3) in cultured CCh fibroblasts.Methods Conjunctival fibroblasts wereisolated and cultured from CCh-derived and cataract-derived human conjunctiva explants.The cells were treated using20 ng/ml PBS,TNF-α or IL-1β for 4 hours,respectively.The expression levels of MMP-1,MMP-3,TSG-6 and PTX3genes and proteins were detected by quantitative real time PCR and Western blot assay,respectively.Results Thesecond-generation cells showed a long and fusiform shape with ovoid nucleus and radial agreement,and the cellprocessors connected each other.The differences of the relative expression levels of MMP-1,MMP-3,TSG-6 and PTX3mRNA in the cells were significantly different between CCh group and cataract group after being treated by PBS,TNF-αand IL-1 β (MMP-1 mRNA:Fgroup =2.611,P =0.116;Fi =161.564,P =0.000;MMP-3 mRNA:Fgroup =5.201,P =0.029;Fintervene =211.021,P =0.000;TSG-6 mRNA:Fgroup =47.209,P =0.000;Fintervene =119.340,P =0.000;PTX3 mRNA:Fgroup =40.512,P =0.000;Fintervene =93.935,P =0.000).Compared with the cataract group with PBS treatment,the expression levels of MMP-1,MMP-3,TSG-6 and PTX3 mRNA were significantly elevated in the CCh group with PBS treatment or the cataract group with TNF-α and IL-1 β treatment (all at P＜0.05).Compared with the CCh group with PBS treatment,the expression levels of MMP-1,MMP-3,TSG-6 and PTX3 mRNA were significantly elevated in the CCh group with TNF-α and IL-1β treatment (all at P ＜ 0.05).The differences of the relative expression levels of MMP-1,MMP-3,TSG-6 and PTX3 proteins in the cells were significantly different between CCh group and cataract group after being treated by PBS,TNF-α and IL-1 β (MMP-1:Fgroup =84.702,P =0.000;Fint =48.900,P =0.000;MMP-3:Fgroup =112.818,P =0.000;Fint =194.980,P =0.000;TSG-6:Fgroup =56.867,P =0.000;Fint =70.356,P =0.000;PTX3:Fgroup =1.488,P =0.231;Fint =89.872,P =0.000),and the expression changes of MMP-1,MMP-3,TSG-6 and PTX3 proteins were coincident with the genes among the groups with various treatments.Conclusions The expressions of MMP-1,MMP-3,TSG-6 and PTX3 in conjunctival fibroblasts are upregulated in CCh eyes.The interaction of TNF-α and IL-1 β with MMPs is probably involved with the pathogenesis and development MMPs probably.

BACKGROUNDTo evaluate the diagnostic value of flow cytometric DNA analysis of sputum cells in lung cancer patients.

METHODSThe DNA content of sputum cells was determined by flow cytometry in 44 patients (29 patients with lung cancer, and 15 patients with benign pulmonary disease). The results of DNA content of sputum cells were compared with those of cytologic morphology of sputum cells.

RESULTSThe last pathologic diagnosis was used as a diagnostic criterion, the sensitivity of DNA heteroploidy analysis was 82.8% , which was significantly higher than that of sputum cytology (82.8% vs 27.6%, P < 0.005); and the positive rate of heteroploidy in sputum samples in stage III and IV disease was significantly higher than that in stage I and II disease (87.5% to 76.9%, P < 0.002 5). In one case, the heteroploidy was found 10 months in advance of cytometry. In the control, heteroploidy was detected in 33.3% (2/6) patients with inflammatory pseudotumor and 50.0% (2/4) patients with tuberculous nodule, who were found with positive staining of Ki67 and PCNA.

CONCLUSIONSFlow cytometry seems to be a valuable adjunctive method for the diagnosis of lung cancer, and probably for the early diagnosis.There are clonal changes in some inflammatory pseudotumor and tuberculous nodule.
