The value of the "touching-bone" acupuncture technique in clinical application was explained through the investigation on the origin of the theory of the "touching-bone" acupuncture technique, the analysis on the characteristics of acupoint selection, the introduction of clinical characteristics and the discussion on the mechanism of acupuncture in treatment. The "touching-bone" acupuncture technique refers to deep needling method, originated from the short needling and needling of the ancient needling methodslisted in the . The target points are the reaction sites on meridian near to bone and the attachments of soft tissues on bone. During the needle insertion, the needle tip is thrust deeply to the bone or the needle body is closely attached to the bone so as to stimulate periosteum specifically. This needling technique contributes to the satisfactory effect on spasmodic, deep-located and intractable pain disorder, motor system diseases, mental diseases and cerebral diseases, etc. Hence, this acupuncture technique deserves to be promoted in clinical application and explored in research.

Objective To investigate the sexual behavior types, condom use and influencing factors of gonorrhea patients in Yunnan Province, and to provide evidence for the adjustment of sexually transmitted disease (STD) prevention and control strategy. Methods A cross-sectional study was carried out to investigate gonorrhea patients in 14 STD clinics in 7 more prevalent prefectures (cities) of Yunnan Province. A questionnaire survey was conducted to investigate the socio-demographic and sexual characteristics of the patients in a one-to-one way. Multiple Logistic regression model was used to analyze the influencing factors of sexual behavior. Results A total of 179 cases of gonorrhea were investigated. The average age was (29.01±8.93) years old. 95.53% (171/179) patients were 40 years old and 88.27% were male patients (158/179). Unmarried patients accounted for 55.31% (99/179). Service and self-employed patients accounted for 34.64% (62/179) and 23.46% (42/179) respectively. The rate of sexual intercourse with opposite sex was 98.32% (176/179), the rate of men who have sex with men was 1.68% (3/179) and the rate of having more than two sexual partners was 27.93% (50/179). The rate of sexual intercourse between temporary partners, spouses/fixed partners and commercial partners were 53.07% (95/179), 37.99% (68/179) and 8.94% (16/179) respectively. Recent sexual activity had lower condom use rate, 17.89% (17/95), 19.12% (13/68) and 18.75% (3/16) respectively. The main ways for gonorrhea patients to make temporary partners were friend introductions or gatherings, accounting for 66.32% (63/95). Condom use in male patients was worse than that in female patients (OR=0.234, 95% CI: 0.084-0.656, P=0.006). Conclusions The patients with gonorrhea were mainly unmarried young adults. The main risk behaviors were unprotected behaviors between heterosexual temporary and spouse/fixed sexual partners. The condom use consciousness was generally low. The promotion of safe sex education for young adults should be further strengthened, with special attention to the use of condoms for temporary sexual behavior and spouse/fixed sexual intercourse.

Objective: To evaluate the indication, safety and effectiveness of transoral robotic surgery (TORS) for oropharyngeal cancer based on our preliminary experience. Methods: Twelve patients, including six with tonsil cancer, five with tongue base cancer and one with posterior pharyngeal wall cancer, who underwent TORS with Da Vinci Si surgical system from March 2017 to October 2018 at Tongji Hospital of Huazhong University of Science Technology were respectively analyzed. And the surgical time, intraoperative blood loss, postoperative local bleeding, dyspnea, nerve function injury, oral intake time, whether or not to receive chemoradiotherapy were analyzed. Results: All tumors in the 12 patients were en bloc removed by TORS. Surgical time ranged from 25 to 80 min with an average of 34.2 min. The blood loss ranged from 10 ml to 50 ml with an average of 20.8 ml. The recovery time for oral intake ranged from 1 day to 30 days with an average of 8.4 days. No patient underwent tracheostomy after TORS. Also, no patient manifested with airway obstruction, bleeding or nerve injury symptoms after operation. All 12 patients reached pathologically negative surgical margins. The patients were followed up for 4 to 22 months, with a median of 12 months. All patients who combined with more advanced than T3 stage, or more advanced than N2 stage were recommended to oncologist, then, followed with radiotherapy or chemoradiotherapy if no relevant contradictions occurred. No local recurrence or distant metastasis case was found. Conclusion With proper indications, the application of TORS in oropharyngeal cancer is a relatively safe, effective and minimal invasive therapy, which merits more clinical applications.

Objective To evaluate the risk factors and sonographic findings of pregnancies complicated by placenta increta or placenta percreta. Methods Totally, 2219 cases were retrospectively analyzed from 20 tertiary hospitals in China from January 2011 to December 2015. The data were collected based on the original case records. All cases were divided into two groups, the placenta increta (PI) group (79.1％, 1755/2219) and the placenta percreta (PP) group (20.9％, 464/2219), according to the degree of placental implantation. The risk factors and sonographic findings of placenta increta or percreta were analyzed by uni-factor and logistic regression statistic methods. Results The risk factors associated with the degree of placental implantation were age, gravida, previous abortion or miscarriage, previous cesarean sections, and placenta previa (all P<0.05), especially, previous cesarean sections (χ2=157.961) and placenta previa (χ2=91.759). Sonographic findings could be used to predict the degree of placental invasion especially the boundaries between placenta and uterine serosa, the boundary between placenta and myometrium, the disruption of the placental-uterine wall interface and loss of the normal retroplacental hypoechoic zone(all P<0.01). Conclusions Previous cesarean sections and placenta previa are the main independent risk factors associated with the degree of placenta implantation. Ultrasound could be used to make a prenatal suggestive diagnosis of placenta accreta spectrum disorders.

Objective To evaluate the prognostic value of a novel prediction model based on fibrinogen concentration in combination with neutrophil-to-lymphocyte ratio (F-NLR score) in patients with esophageal squamous cell carcinoma (ESCC) receiving neoadjuvant therapy and investigate their relationship with pathologic complete response (pCR).Methods Clinical data of 218 eligible ESCC patients treated with neoadjuvant therapy in the Affiliated Cancer Hospital of Zhengzhou University between 2012 and 2015 were retrospectively analyzed.The cut-off values for fibrinogen and neutrophil-to-lymphocyte ratio (NLR)were defined by the receiver operating characteristic (ROC) curve.The effects of different F-NLR scores on survival and pCR were evaluated.The survival rate was analyzed using the Kaplan-Meier method.The relationship among fibrinogen,NLR and pCR was analyzed by using Wilcoxon rank sum test.Results The 3-year overall survival (OS) rates with F-NLR scores of 0,1 and 2 were 72.1％,66.5％ and 50.2％(P=0.010),respectively.The corresponding 3-year disease-free survival (DFS) rates were 64.1％,60.2％ and 45.4％ (P=0.012),respectively.The clinical prognosis of patients with an F-NLR score of 2 was significantly worse compared with those of their counterparts with an F-NLR score of 0-1 (P=0.003).Multivariate analysis demonstrated that the F-NLR score (P=0.004) and TNM stage (P=0.000) were the independent prognostic factors.Conclusions The F-NLR score can be used as an independent prognostic factor for ESCC patients treated with neoadjuvant therapy,which is promising supplement to current TNM staging system,thereby facilitating more accurate risk stratification analysis and achieving individualized multidisciplinary treatment for ESCC patients.

Objective To investigate the neuroprotective effect of Benztropine on retinal ganglion cells (RGCs) death and optic nerve injury in rats model of non-arteritis anterior ischemic optic neuropathy (rNAION).Methods A total of 25 Sprague-Dawley rats were randomly divided into Benztropine treatment group (n=13)and PBS control group (n=12).The right eye was set as the experimental eye.rNAION model was established by using rose Bengal combined with laser photodynamic method.The rats in the Benztropine treatment group were received intraperitoneal injection with Benztropine 10 mg/kg (0.2 ml) daily for 3 weeks,while the rats in the PBS control group were received intraperitoneal injection with an equal volume of PBS.At 1,3 and 7 days after modeling,the retinal and optic disc conditions of the rats were observed by direct ophthalmoscopy.Retrograde labeling,fluorescence microscopy and transmission electron microscopy were used to observe the survival of RGCs and the damage of the optic nerve myelin and axon at 4 weeks after modeling.The RGCs density and survival rate of the two groups were compared by One-Way Anova.Results At 1 and 3 days after modeling,the optic disc edema was observed in the rats of rNAION model group.At 7 days after modeling,the optic disc edema decreased and the boundary was blurred compared with 3 days after modeling.After 4 weeks,the RGCs density in the PBS group was 308± 194/mm2 and the survival rate was 13.7％.The density of RGCs in the Benztropine group was 1173+868/mm2 and the survival rate was 47.6％.The differences of RGCs density and survival rate were significant between the two groups (F=7.552,8.184;P=0.015,0.012).Myelin disintegration,axon degeneration,onion-like body and gliosis were observed in the optic nerve sections of rNIAON in the PBS group,while the damage ofaxon and myelin structure in the Benztropine group was significantly less than that in the PBS group.Conclusions Benztropine group showed higher RGC survival rate,less damage ofaxon and myelin structure on rNAION model.This study explored the potential neuroprotective effect of Benztropine.

Objective To evaluate the value of nested polymerase chain reaction (PCR) for the rap-id detection of pathogens in children with severe pneumonia. Methods We prospectively enrolled the pa-tients with severe community-acquired pneumonia admitted to pediatric intensive care unit (PICU) in Shang-hai Children′s Hospital from January 2017 to June 2018. The sputum for PCR were collected within 24 h after PICU admission. Both nested PCR and routine microbiological methods were performed. Respiratory Panel (R-Panel) based on nested PCR could detect 17 kinds of respiratory pathogen at the same time. Results A total of 65 patients were enrolled in this study and the samples were detected using both R-Panel and routine microbiological method. (1) A total of 15 patients (23. 08 %) showed positive routine microbiological de-tection including 13 cases with virus-positive and 2 cases with mycoplasma-positive; (2) A total of 38 pa-tients (58. 46%) showed positive results using R-Panel within 2 h including 46 cases with virus-positive and 5 cases with mycoplasma-positive. The mainly primary infection was human rhinovirus and enterovirus in 15 cases (23. 08%),followed by adenovirus in 10 cases (15. 38%); and the positive rate of 2 or more patho-gens was 18. 46% (12/65);(3) The rate of adenovirus-positive using R-Panel was significantly higher than that using routine microbiological methods (15. 38 % vs. 4. 62%,χ2 ＝4. 188,P＝0. 041); the sensitivity of R-Panel for detection of adenovirus,respiratory syncytial virus,and parainfluenza virus was significantly high-er than those of routine microbiological methods (100% vs. 30%,χ2 ＝107. 692;50. 00% vs. 16. 67%,χ2 ＝ 24. 442;100% vs. 80%,χ2 ＝22. 222;100% vs. 40%,χ2 ＝85. 714; all P <0. 001). Conclusion R-Panel using nested PCR is a rapid,sensitive,and specific method for the detection of pathogens in children with severe community acquired pneumonia,which is valuable for targeted therapy in time.

Objective To explore the normal reference range of fetal gallbladder in 28 to 35 weeks of pregnancy under magnetic resonance imaging characteristics, observe and explore the growth and development of fetal gallbladder, and provide a new detection method for evaluating fetal growth and development for prenatal examination. Methods One hundred single pregnant women who had underwent fetal abdominal magnetic resonance imaging from June 2017 to May 2018 in Dalian Municipal Women and Children′s Medical Center were selected. The pregnant women were divided into 2 groups according to the gestational weeks: group A (pregnancy 28 to 31 weeks, 64 cases) and group B (pregnancy 32 to 35 weeks, 36 cases). The length, width and transverse diameter of fetal gallbladder were measured by magnetic resonance, and the gallbladder volume was calculated. Results In group A, magnetic resonance result showed that 1 case had no gallbladder and 1 case had double gallbladder, but the fetal gallbladders of these 2 cases were normal after birth. The display rate of fetal gallbladder in group A was 98.4% (63/64), and that in group B was 100.0% (36/36); the abnormal rate in group A was 3.1% (2/64), and that in group B was 0. The length, width, transverse diameter and volume of gallbladder in group B were significantly higher than those in group A: (16.5 ± 6.0) mm vs. (13.2 ± 4.2) mm, (6.5 ± 3.5) mm vs. (5.2 ± 1.1) mm, (6.8 ± 2.6) mm vs. (6.4 ± 3.4) mm and (373.3 ± 284.1) mm3 vs. (258.5 ± 232.4) mm3, and there were statistical differences (P＜0.05). Conclusions Fetal magnetic resonance during lategestation has the new means of prenatal evaluation of fetal growth and development, which has clinical application value.

As known,simultaneous determination of various chemical indicators is one of the future trends in quality control of traditional Chinese medicines because of the extremely complex chemical compositions. This project is to screen the quality markers that can accurately control the quality of the Bufonis Venenum by exploring the intrinsic correlation of components. In this study,venom of Bufo bufo gargarizans from 17 different sources were used as research samples,and the contents of 7 bufogenin were determined by HPLC-DAD. Then,the data obtained were analyzed by Spearman correlation analysis and principal component analysis( PCA). In addition,a stepwise regression analysis was used to establish a predictive model for the contents of the seven bufogenin components( independent variable) and the total contents of the bufogenin( dependent variable). The results indicated that there is a significant positive correlation between the contents of telocinobufagin and cinobufotalin,and there is a significant positive correlation between the contents of bufalin,cinobufagin and resibufogenin. In contrast,the contents of telocinobufagin and cinobufotalin are negatively correlated with the contents of bufalin,cinobufagin and resibufogenin. However,the correlation between gamabufotalin and bufotalin and other components are not obvious. Furthermore,further study found that there is a correlation between the sum of the contents of bufalin,cinobufagin and telocinobufagin and the total contents of the bufogenin. In fact,the application of bufalin,cinobufagin and telocinobufagin as the quality control indicators of the Bufonis Venenum can better reflect the quality characteristics of the Bufonis Venenum compared with the previous quality control indicators. The conclusions will provide a reference for the revision of the quality standards of the Bufonis Venenum.
