Objective:To establish the preliminary somatosensory data stratified by gender, age group, and sites in the trigeminal region through standardized quantitative sensory testing on healthy individuals, and to evaluate the effects of gender, age, and sites on somatosensory functions. Methods: The stan-dardised QST battery developed by the German Research Network on Neuropathic Pain consists totally of 13 different parameters. A total of 70 healthy individuals participated. The subjects were stratified into two groups according to age: younger group ( 16 female, 16 male, age 24 -40 years old ) and elder group (20 female, 18 male, age 41-69 years old) . The test was performed bilaterally over the infraor-bital, mental, and hand regions. Results:The preliminary orofacial somatosensory data stratified by gen-der, age group, and sites were presented. Female were more sensitive than male for most of the parame-ters ( P<0 . 05 ) . Age had a significant effect on most of the parameters ( P<0 . 05 ) , the younger group was more sensitive compared with the elder group (P<0. 01) for heat pain threshold (HPT): younger group (38. 07 ± 2. 94) ℃, elder group (39. 85 ± 3. 52) ℃;warmth detection threshold (WDT):youn-ger group (1.40 ±0.74) ℃, elder group (1.89 ±1.14) ℃; mechanical detection threshold (MDT):younger group (0. 73 ± 1. 66) mN, elder group (1. 41 ± 2. 82) mN; pressure pain threshold ( PPT):younger group ( 171. 71 ± 92. 51 ) kPa, elder group ( 196. 36 ± 73. 73 ) kPa; cold pain threshold (CPT):younger group (25. 90 ± 5. 38) ℃, elder group (21. 64 ± 6. 78) ℃; cold detection threshold (CDT):younger group ( -0. 97 ± 0. 55) ℃, elder group ( -1. 36 ± 0. 90) ℃, and wind-up ratio (WUR):younger group (3. 33 ± 2. 20), elder group (2. 67 ± 1. 68). The inverse results were demon-strated for mechanical pain threshold ( MPT ): younger group ( 111. 50 ± 88. 93 ) mN, elder group (104. 49 ± 94. 94) mN;mechanical pain sensitivity (MPS):younger group (6. 96 ± 5. 61), elder group (8.93 ±6.53), and vibration detection threshold (VDT): younger group (7.44 ±0.52) scale, elder group (7.55 ±0.48) scale (P<0.05). Somatosensory function was site dependent (P<0.001), the two trigeminal sites ( infraorbital and mental) were more sensitive than the hand for CDT, HPT, WDT, thermal sensory limen (TSL), MDT, MPT, MPS, and PPT (P <0. 001), but the inverse result was observed for VDT ( P <0 . 001 ) . Conclusion: The preliminary orofacial somatosensory data of Han Ethnicity stratified by gender, age group, and sites were established. The study evaluated the effects of gender , age and sites on orofacial somatosensory functions by employment standardized quantitative senso-ry testing.

Objective To investigate the influence of plasma exchange with acupuncture point injection therapy on liver fibrosis indexes in patients with severe hepatitis. Methods Sixty patients with severe hepatitis were randomly divided into group A with 29 cases receiving plasma replacement and group B of 31 cases receiving astragalus injection at Zusanli point in addition to plasma replacement. Changes of liver fibrosis indexes including serum hyaluronic acid (HA), laminin (LN), collagenⅣ(Ⅳ-C), typeⅢpre-collagen (PCⅢ) were observed, which were compared with those from group C with 30 healthy subjects. Results Before treatment, there was no statistical significance in comparison of liver fibrosis index in group A and B (P>0.05), but all the indexes were higher than those in group C (P<0.001). After treatment, the level of each index in group A and B was down with a more significant change in group B and the comparison of both groups indicated statistical significance (P<0.05 or P <0.001);Compared with those in group C, changes ofⅣ-C, PCⅢin group B showed no significant difference (P>0.05). Conclusion Plasma exchange with astragalus injection at Zusanli point can effectively improve liver fibrosis indexes in patients with severe hepatitis and then improve the prognosis of patients.

ObjectiveTo observe the clinical efficacy of plasmapheresis plus acupoint injection in treating severe hepatitis. MethodSixty patients with severe hepatitis were randomized into a treatment group of 31 cases and a control group of29 cases. The two groups both received plasmapheresis in addition to the comprehensive internal medicine treatment, while thetreatment group simultaneously received acupoint injection withHuang Qi(Radix Astragali) at Zusanli (ST 36). After the intervention, the symptoms, signs, liver function, blood coagulation, and blood ammonia were observed in the two groups.ResultAfter the intervention, the symptoms, signs, and biochemical indexes were significantly improved,and theindexes in the treatment group were significantly different from that in the control group (P<0.05,P<0.01), and the total effective rate of the treatment group was markedly higher than that of the control group (P<0.05).ConclusionPlasmapheresis plus acupoint injection can effectively improve the short-term condition of the patients, enhance therapeutic efficacy, with fewer adverse reactions.

Objective To probe the clinical diagnosis value of high frequency ultrasonography (HFUS) in thyroglossal duct cyst(TDC). Methods Forty-one TDC were taken HFUS and the location, boundary,shape,interal echo of lesions and the relation to hyoid bone were observed. The periphery and internal blood flow signal were detected by color Doppler flow imaging. The results of HFUS were compared with those of pathology after operation. The cases were divided into groups according to pathological types and were compared with acoustic image shows. Results All cases were diagnosed TDC by pathology after operation. Internal walls of 9 TDC consist of cilium columnar epithelium, 19 consist of stratified pavement epithelium and 13 consist of this two epitheliums. HFUS showed different pathological types had different ultrasonic appearances. In this study, 77.8%(7/9) TDC with columnar epithelium showed echoless,84.2 (16/19) TDC with pavement epithelium showed similar solid echopattern and TDC with two epitheliums mainly showed similar solid echopattern and multi-room cyst. Hyperechogenicity of hyoid bone displayed around the lesion in 80.5%(33/41)TDC. No blood flow signal showed in 41 TDC and a little punctiform blood flow signal showed in the periphery of 5 TDC. The diagnose accordance rate of HFUS in TDC was 95.1%(39/41). Conclusions HFUS can clearly show the location, boundary, shape,interal echo of TDC and its relation to hyoid bone. HFUS is important for diagnosis and differential diagnosis of TDC.

Objective To probe the value of color Doppler ultrasonography (CDU) in differential diagnosis of the pure mucinous adenocarcinoma of breast (PMAB) and adenofibroma of breast (AFB).Methods Twenty-five cases of PMAB and 30 cases AFB were examined by CDU. The sonographic appearance, interior and peripheral blood flow distribution and Doppler frequency of the tumors were observed and analyzed. The results of the diagnoses of CDU and the pathologies were compared. Results The diagnostic rates of PMAB and AFB by CDU were 76.0% and 93.3%, respectively. The clear peplos was observed in 90% of AFB, and internal even echoes. Yet no peplos was observed in PMAB, and the internal echoes of most PMAB were confused and disordered. The detection rate of Ⅰ ～ Ⅱ stage blood flow in adenofibroma of breast was only 40% and that of Ⅰ ～ Ⅲ stage blood flow in PMAB was high to 76%.The detection rate of blood flow stage and the resistant index (RI) of the blood flow frequency spectrum of PMAB and AFB were significantly different. Conclusions CDU has significant clinical value in differential diagnosis of pure mucinous adenocarcinoma and adenofibroma of breast.

Objective To investigate the effects of different liver protective drugs on preventing liver injury induced by anti-tuberculosis drugs. Methods Retrospective analysis was made on 355 patients with primary pulmonary tuberculosis during intensified time. The patients received silibinon and bicyclol to prevent liver injury. 82 patients with TB were treated as control group during the same time. Results The number of patients with liver injury in silibinon group and bicyclol group were 16 cases (14.7%) and 55 cases (22.4%) respectively. The number of control group with liver injury was 9 cases (11.0%) (χ2 = 3.627,P > 0.05). The liver injuries within 4 weeks were mainly counted in. There is no difference between intervention and control groups(χ2 = 0.414,P > 0.05). There is no difference between three groups in liver injury degree (U = 0.288,P> 0.05). Conclusion Without high risk factors, anti-inflammatory and enzyme reduction drugs have no significant protective effects on liver injury caused by anti-tuberculosis drugs.

Objective To probe the value of color Doppler flow imaging(CDFI) in diagnosis of borderline ovarian epithelial tumors (BOET).Methods Thirty-six cases of BOET,139 cases of ovarial cystadenoma and 66 cases of ovarial cystadenocarcinoma were diagnosed pathologically.All cases were preoperatively detected by CDFI.Tumor sign CA125 was also detected.The size,boundary,internal echo and internal flow distribution were observed.The results of CDFI of different diseases were contrasted.Results Ultrasonic diagnosis rate was 75 ％ (27/36) in BOET,90.6 ％ (126/139) in ovarial cystadenoma and 92.4 ％ (61/66) in ovarial cystadenocarcinoma.Positive rate of CA125 of ovarial cystadenocarcinoma was obviously higher than those of BOET and ovarial cystadenoma.Positive rate of CA125 of ovarial cystadenocarcinoma containing solid was especially higher than that of BOET containing solid.Ovarial cystadenoma mainly showed single cavity,few or without solid as well as hematoasthenia or asanguineous.BOET and ovarial cystadenocarcinoma mainly showed multi-cavity,more solid as well as plentiful blood flow.Blood flow of BOET distributed regularly comparing with ovarial cystadenocarcinoma.Conclusions Characteristics of CDFI combining results of CA125 can provide powerful reference for diagnosise and differentiate diagnosis of BOET and more information diagnostic information for clinic to chosing treatment scheme and postoperative long-term follow-up.

Objective:This study was to explore "Internet + nursing service" mode, the tumor specialist nurses nursing service experience and feelings, in the process of mining "Internet + nursing service" model of current existing problems and future development direction, discussed under the background of constructing a new mode of medical and health services, how to expand the tumor specialized subject "Internet + nursing service" the breadth and depth to improve the quality of life of cancer patients and nursing service benefit.Methods:Through the review of the literature, the focus and direction of the research were determined. A semi-structured interview was conducted with 12 oncology nurses enrolled in "Internet + nursing service" by qualitative research. Colaizzi seven-step method was used to encode, classify and extract the data.Results:The experience of "Internet + nursing service" carried out by oncology nurses can be summarized into the following five themes: Be more willing; professional identity of specialist nurses is higher (self-identity, patient identity, social identity); Multiple psychological experience (stress experience: the limitation of specialized operation and the pressure of communication; Adaptive experience: "Specialist cooperation and two-person home visit mode" is well adapted). The time and economic cost of specialist services are higher. The matching degree of service item supply and market demand is insufficient.Conclusions:In order to further expand the depth and breadth of "Internet + nursing service" in oncology, and to benefit more cancer patients in the long-term treatment and rehabilitation process, it is necessary to improve the recognition degree of nurse specialty, so as to improve the willingness to work; increase nurse training to enhance nurses' comprehensive coping ability; improving policy and economic support based on the characteristics of tumor diseases; improve the oncology "Internet + nursing services" project.
