Objective:To seek specific response points on the body surface of patients with primary dysmenorrhea(PD)by observing blood perfusion unit(PU)at different points of the three Yin meridians of foot using laser speckle contrast imaging(LSCI). Methods:Eighty PD patients were recruited as a PD group,and 80 healthy female undergraduates were taken as a normal group.During one menstrual cycle(before menstruation,during menstruation,and 3 d after menstruation),each participant was examined using the LSCI system to determine PU at bilateral Taixi(KI3),Taibai(SP3),Taichong(LR3),Shuiquan(KI5),Diji(SP8),Zhongdu(LR6),Sanyinjiao(SP6),and Xuehai(SP10)and non-acupuncture points.The researchers in charge of point location,operation,and statistical analysis were not aware of grouping.PU at the detection spots was taken as the outcome measure. Results:Compared with the normal group,the PD group showed increases in PU at right Taixi(KI3)before menstruation(P<0.05)and at bilateral Zhongdu(LR6)and right Diji(SP8)during menstruation(P<0.05).At the other time points,significance was not found between the two groups in comparing PU at the detected spots. Conclusion:Compared with healthy participants,PD patients present specific changes in PU at Taixi(KI3),Diji(SP8),and Zhongdu(LR6)at specific time points during the menstrual cycle,which provides a reference for acupuncture-moxibustion treatment of PD in clinical settings.

Experience of Thoracotomy and Robot-assisted Bronchial Sleeve Resection after Neoadjuvant Chemoimmunotherapy for Local Advanced Central Lung Cancer / 中国肺癌杂志

BACKGROUND@#Immunoneoadjuvant therapy opens a new prospect for local advanced lung cancer. The aim of our study was to explore the safety and feasibility of robotic-assisted bronchial sleeve resection in patients with locally advanced non-small cell lung cancer (NSCLC) after neoadjuvant chemoimmunotherapy.@*METHODS@#Data of 13 patients with locally advanced NSCLC that underwent bronchial sleeve resection after neoadjuvant chemoimmunotherapy during August 2020 and February 2021 were retrospectively included. According to the surgical methods, patients were divided into thoracotomy bronchial sleeve resection (TBSR) group and robot-assisted bronchial sleeve resection (RABSR) group. Oncology, intraoperative, and postoperative data in the two groups were compared.@*RESULTS@#The two groups of patients operated smoothly, the postoperative pathology confirmed that all the tumor lesions achieved R0 resection, and RABSR group no patient was transferred to thoracotomy during surgery. Partial remission (PR) rate and major pathological remissions (MPR) rate of patients in the TBSR group were 71.43% and 42.86%, respectively. Complete pathological response (pCR) was 28.57%. They were 66.67%, 50.00% and 33.33% in RABSR group, respectively. There were no significant differences in operative duration, number of lymph nodes dissected, intraoperative blood loss, postoperative drainage time and postoperative hospital stay between the two groups, but the bronchial anastomosis time of RABSR group was relatively short. Both groups of patients had a good prognosis. Successfully discharged from the hospital and post-operative 90-d mortality rate was 0.@*CONCLUSIONS@#In patients with locally advanced central NSCLC after neoadjuvant chemoimmunotherapy can achieve the tumor reduction, tumor stage decline and increase the R0 resection rate, bronchial sleeve resection is safe and feasible. Under the premise of following the two principles of surgical safety and realizing the tumor R0 resection, robot-assisted bronchial sleeve resection can be preferred.

Objective:To compare the clinical efficacy and cost of robot-assisted laparoscopic adrenalectomy with da Vinci Xi and Si surgical system in the treatment of adrenal tumors.Methods:The clinical data of 99 patients performing robotic-assisted laparoscopic adrenalectomy in our hospital between June 2019 and December 2020 were retrospective analyzed. Among them, 57 cases were Si system robot assisted laparoscopic adrenalectomy (group Si), 35 male, 22 female; age (45.6±14.0)years; BMI(21.0±1.2); 6 with diabetes, 10 hypertension, 14 with abdominal surgery; 28 left, 29 right; 9 ASA score ≥3; tumor diameter (3.9±1.2)cm. There were 42 cases of Xi system robot-assisted laparoscopic adrenalectomy (group Xi), 21 male, 21 female; age(44.8±14.5)years; BMI(21.4±1.8); 2 with diabetes, 12 hypertension, 11 with abdominal surgery; 15 left, 27 right; 7 with ASA score ≥3; tumor diameter (3.7±1.1) cm. Sex, age, BMI, comorbidities, history of abdominal surgery, lateral division, ASA score, and tumor diameter were not significantly different between the two groups ( P>0.05). Operation method: except for the different docking procedures, the same surgical procedures were roughly performed in the two groups. The docking method of the Si group was the doctor holding the attractor as the guide. The operating room nurse introduced the robot cart under the guidance of the attractor, and then completed the docking.Group Xi docking adoptd the own laser positioning system of the robot system, without manual positioning and guidance; the mechanical arm of the Xi system was also more flexible. Complications were graded according to the Clavien-Dindo grading system. Comparing the treatment effect, safety, and cost of the two groups were compared. Results:The anesthesia times in the Si and Xi groups were (140.0±24.3) min and (125.6±26.4) min ( P=0.006), respectively. The surgical times in the Si and Xi groups were (109.0±18.8) min and (98.8±20.7) min (P=0.013), respectively. The docking times between the Si and Xi groups were (7.8±1.4) min and (5.0±0.9) min ( P<0.001), respectively. The estimated intraoperative blood loss in the Si and Xi groups was (121.5±70.8) ml and (124.7±68.9) ml ( P=0.824), respectively. The postoperative indwelling times of the drainage tube in the Si and Xi groups were (3.4±1.2) d and (3.4±1.3) d ( P=0.892), respectively. Postoperative bed times in the Si and Xi groups were (2.3±1.0) d and (2.5±1.2) d ( P=0.419), respectively. Postoperative hospitalization times in the Si and Xi groups were (6.4±1.5) d and (6.2±1.5) d ( P=0.484), respectively. Post Clavien ≥ grade 3 complications were four and two in groups Si and Xi, respectively ( P=0.642). The total cost during hospitalization in the Si and Xi groups was (51 975.2±7 320.8) Yuan and (56 830.9±8 392.5) Yuan, respectively ( P=0.003). The surgery and consumables costs for the Si and Xi groups were (23 785.3±4 063.1) Yuan and (28 021.2±6 066.8) Yuan ( P<0.001), respectively. Conclusions:Compared with the Si system, the Xi system robot-assisted laparoscopic adrenalectomy can provide similar perioperative results and safety, and shorten the time of anesthesia and surgery, but the total cost of hospitalization is increased.

Impacto de la anestesia intravenosa en cirugía robótica para paciente de alto riesgo sometido a cirugía oncológica de larga duración en el Centro Médico Naval / Impact of intravenous anesthesia in robotic surgery for high-risk patient undergoing long-term oncologic surgery at the Naval Medical Center

Resumen: La práctica de cirugía robótica es un proceso complejo que implica desarrollo y tecnología no sólo en el campo de la cirugía, sino también en el campo de la anestesiología. Implica un proceso multifactorial, ya que ha generado un cambio drástico multidisciplinario basado en tecnología de punta que pretende ofrecer mejores condiciones durante el manejo perioperatorio en cirugía robótica. La anestesia total intravenosa cumple objetivos específicos en relación a la posición del paciente, relajación cerebral, neuroprotección, hemodinamia, pérdida y recuperación de la conciencia, parálisis neuromuscular, parámetros ventilatorios, etc. Ofrece seguridad y calidad al paciente durante el procedimiento con una mínima interferencia con el monitoreo electrofisiológico y permite modular la profundidad anestésica desde una neurosedación hasta una anestesia general, de acuerdo a las diferentes etapas de la cirugía. Un factor atribuible a la anestesia moderna para el éxito de la cirugía robótica es usar diferentes agentes anestésicos que promuevan inducción, mantenimiento y emersión anestésica más rápida y suave, a fin de reducir el tiempo de recuperación del estado de conciencia, funciones básicas y psicomotoras como la anestesia general multimodal.

Abstract: The practice of robotic surgery is a complex process, involving development and technology; not only in the surgery field but also in the anesthesiology field. It implies a multifactorial process since it has generated a drastic multidisciplinary change based on state-of-the-art technology; which aims to offer better conditions during perioperative management in robotic surgery. Intravenous Total Anesthesia accomplishes specific objectives in relation to patient position, brain relaxation, neuroprotection, hemodynamics, loss and recovery of consciousness, neuromuscular paralysis, ventilatory parameters, providing safety and quality during the procedure; with minimal intervention during electrophysiological monitoring and enabling anesthetic depth to be modulated from neurosedation to general anesthesia, according to the different stages of the surgery. A factor attributable to modern anesthesia for robotic surgery success is to employ different anesthetic agents promoting induction, maintenance of general anesthesia, smother and faster anesthetic emersion, for the purpose of reducing recovery time of the state of consciousness), basic and psychomotor functions; as is the general multimodal anesthesia.

Acupuncture combined with medication for postherpetic neuralgia affecting the head and face: a randomized controlled trial / 针灸推拿医学（英文版）

Objective: To observe the efficacy of needling the Xi-Cleft points of yang meridians plus topical surrounding needling and pregabalin in treating postherpetic neuralgia (PHN) affecting the head and face and its influence on quality of life (QOL). Methods: Eighty patients with PHN affecting the head and face were randomized into an acupuncture-medication group and a Western medication group by their visiting sequence, with 40 cases in each group. The Western medication group took pregabalin capsules orally, 75 mg each time, twice a day. The dosage could increase to 150 mg each time and twice a day within 1 week based on the efficacy and tolerance. The treatment lasted for 5 weeks. The acupuncture-medication group was given additional surrounding needling at the herpes zoster on the head and face, and Xi-Cleft points of yang meridians were chosen according to the affected area for acupuncture, once every other day, for 5 weeks in total. Results: Prior to treatment, there were no significant differences in the visual analog scale (VAS) and QOL scores between the two groups (both P>0.05). After treatment, VAS and QOL scores dropped significantly in both groups (all P<0.01), and were significantly lower in the acupuncture-medication group than in the Western medication group (both P<0.01). The total effective rate was 67.5％ in the Western medication group, versus 92.5％ in the acupuncture-medication group, and the between-group difference was statistically significant (P<0.05). Conclusion: Based on oral administration of pregabalin, needling the Xi-Cleft points of yang meridians and topical surrounding needling can reduce PHN, notably improve patients' QOL, and produce more significant efficacy than oral administration of pregabalin alone.

Objective: To observe the blood perfusion volume variation pattern in the body surface microcirculation at the Yuan-Primary and the Xi-Cleft points during the menstrual cycle in female college students with moderate constitution under normal physiological state of the uterus; to explore the specific laws of the body surface microcirculation at the Yuan-Primary and Xi-Cleft points in response to the uterine qi and blood changes under normal physiological conditions, and to provide the experimental basis for the specificity of acupoints reflecting the uterine function. Methods: Forty-three healthy and moderate constitution female college students with regular menstrual cycles, without dysmenorrhea and not yet giving birth were recruited. Bilateral Yuan-Primary points [Taichong (LR 3), Taibai (SP 3) and Taixi (KI 3)] and Xi-Cleft points [Zhongdu (LR 6), Diji (SP 8) and Shuiquan (KI 5)], belonging to the three yin meridians of foot and adjacent to the spinal cord segment of the uterus, were selected as the detection acupoints; the crossing point of the three yin meridians of foot [Sanyinjiao (SP 6)], the uterus-related meridian acupoint [Xuehai (SP 10)], the uterus-non-related meridian acupoint [Xuanzhong (GB 39)], and the non-meridian non-acupoint point were selected as the control points. The laser speckle blood flow imaging technique was used to monitor the blood perfusion volume in skin microcirculation at the above points at the menstrual, follicular, ovulatory, and luteal phases of the subjects. Results: The blood perfusion volume in the body surface microcirculation at the right Zhongdu (LR 6) at the ovulatory phase was higher than that at the menstrual, follicular and luteal phases (all P<0.05); there was no significant difference in the microcirculation blood perfusion volume at the other points among different phases (all P>0.05). Conclusion: The blood perfusion volume in the body surface microcirculation at Zhongdu (LR 6), the Xi-Cleft point of the Liver Meridian, shows a specific response to qi and blood changes in the uterus of women with moderate constitution.

The occurrence of premature delivery in Xi'an and its influencing factors / 西安交通大学学报(医学版)

Objective: To analyze the factors influencing the occurrence of preterm birth among single live birth neonates in Xi'an so as to provide theoretical basis for the prevention of premature infants. Methods: From July to December 2013, a questionnaire survey was conducted among the childbearing aged women, selected through multistage stratified random sampling method in Xi'an from 2010 to 2013. All of the childbearing aged women under study had definite pregnancy outcomes. The Logistic regression model was adopted to analyze the influencing factors of premature infants. Results: The incidence of preterm birth among single live birth neonates in the last pregnancy in Xi'an was 2.81%. From 2010 to 2013, the incidence of preterm birth was 3.51%, 3.13%, 3.18% and 2.21%, respectively, without significant difference (P=0.248). The incidence of premature delivery in Baqiao District, Beilin District, Lianhu District, Xincheng District, and Yanta District was 3.10%, 2.41%, 2.14%, 3.70% and 2.64%, respectively. There was no significant difference (P=0.259). The incidence of premature delivery in urban residents and rural residents was 2.96% and 2.69%, respectively, with no significant difference (P=0.581). Logistic regression results showed that the occupation as workers [OR=4.06, 95% CI (1.69,9.75)], the history of abnormal pregnancy and delivery [OR=10.68, 95% CI (6.92,16.48)], occupational exposure to risk factors [OR=1.96, 95% CI (1.08,3.57)], drinking [OR=6.31, 95% CI(1.21, 32.99)], radiological examination [OR=6.13, 95% CI (1.64,22.85)], PIH [OR=4.80, 95% CI(2.17, 10.61)], and having disease[OR=0.64, 95% CI (0.43,0.95)] during periconception were the influencing factors of premature infants. Conclusion: The incidence of premature infants in Xi'an from 2010 to 2013 was lower than the national average. Factors such as occupation as workers, the history of abnormal pregnancy and delivery, occupational exposure to risk factors, drinking, radiological examination and PIH during periconception can increase the risk of preterm birth.

Interventional effect of Chinese herbal preparation Xi Fu Pai Chen in rats with silicosis / 中国职业医学

OBJECTIVE: To investigate the interventional effect of the Chinese herbal preparation Xi Fu Pai Chen(XFPC) on pulmonary inflammation and fibrosis in rats with silicosis. METHODS: A total of 144 adult specific pathogen free male SD rats were randomly divided into 6 groups: blank control group, silicosis model group, drug administration control group and groups of low-dose,medium-dose and high-dose XFPC, with 24 rats in each group. Lung silicosis model was established by single inhalation tracheal instillation method, which was treated with 50.0 g/L silica suspension, in groups except in the blank control group. On the 7 th day of modeling, the rats in the drug administration control group were orally given tetrandrine(5 mg/kg body weight), while those in the low-, medium-and high-dose groups were given 43, 86 and 192 g/L of XFPC by atomization inhalation once a day for 20 minutes, 5 days a week for 4 weeks. At the end of drug administration, the histopathological changes of the lung were observed. The number and classification of cells in bronchoalveolar lavage fluid(BALF)were examined, and the levels of malondialdehyde(MDA) and interferon-gamma(IFN-γ) in BALF were measured by enzyme-linked immunosorbent assay. RESULTS: On the 7 th day after modeling, the body weight in the drug administration control group and XFPC high-dose group decreased compared with the blank control group(P<0.05). On the 35 th day after modeling, the body weights of rats in the other 5 groups were lower than that in the blank control group(P<0.05). The pathological changes of lung tissue(infiltration of inflammatory cells, fibrosis and size of silicon nodule) in drug administration control group and XFPC low-dose group were better than those in silicosis model group by naked eyes and under light microscope. The lung coefficient, the proportion of neutrophils and the level of MDA and IFN-γ in BALF of the drug administration control group and XFPC low-dose group decreased(P<0.05), and the proportion of macrophages in BALF increased(P<0.05) compared with the silicosis model group. There was no significant difference in lung coefficients and the relevant indices of BALF between XFPC medium-, high-dose groups and silicosis model group(P>0.05). CONCLUSION: Low dosage XFPC can improve pulmonary fibrosis and inflammation in rats with silicosis, and its mechanism of action may be related to reducing the levels of IFN-γ and MDA in BALF.

Life-threatening hemorrhage secondary to acquired deficiency of coagulation factors VIII and XI related to systemic lupus erythematosus: case report / Hemorragia severa secundaria a deficiencia adquirida de factores VIII y XI de la coagulación relacionada con lupus eritematoso sistémico: reporte de caso

ABSTRACT In patients with autoimmune diseases, the simultaneous occurrence of lupus anticoagulant and blood coagulation factors inhibitors is infrequent and is associated with hemorrhagic events. In these cases, the initial approach requires a thorough interpretation of coagulation laboratory tests and mixing studies to reach a definitive diagnosis. We report the case of a patient with systemic lupus erythematosus and Sjögren's syndrome who presented with hemorrhagic diathesis caused by circulating inhibitors against factors VIII and XI coexisting with lupus anticoagulant. The inhibitors eradication was made with rituximab, achieving good results.

RESUMEN La ocurrencia simultánea de anticoagulante lúpico e inhibidores circulantes contra los factores de la coagulación es infrecuente en los pacientes con enfermedad autoinmune, y está relacionada con eventos hemorrágicos. El abordaje inicial requiere una adecuada interpretación de los tiempos de coagulación y prueba de mezcla con plasma para alcanzar el diagnóstico definitivo. Se reporta el caso de una paciente con lupus eritematoso sistémico y síndrome de Sjögren, quien se presentó con trastorno hemorrágico amenazante de la vida ocasionado por inhibidores circulantes contra los factores VIII y XI de la coagulación en coexistencia con anticoagulante lúpico. El tratamiento de erradicación de los inhibidores se realizó con rituximab, con buenos resultados.

Carrier frequency of autosomal recessive disorders (BC, BLAD, FXID and CVM) in Holstein cows in Jalisco, Mexico

The hereditary autosomal recessive disorders bovine citrullinemia (BC), bovine leukocyte adhesion deficiency (BLAD), factor XI deficiency (FXID), and complex vertebral malformation (CVM) have affected dairy cattle breeding significantly around the world. This study examined the carrier frequency of BC, BLAD, FXID, and CVM autosomal recessive disorders in Bos taurus Holstein cows bred in the Altos Norte region of the state of Jalisco, Mexico. We extracted DNA from 408 random samples of peripheral blood, and then used polymerase chain reaction (PCR) to identify insertion mutations for FXID, and PCR with restriction fragment length polymorphism (PCR-RFLP) for CVM, BC and BLAD. We visualized the PCR products using agarose gel electrophoresis stained with GelRed®. We found that 100% of wild-type (N/N) allele homozygous animals for genes CD18, ASS, and FXI were free of the mutations for BLAD, BC and FXID respectively.

Objective To investigate the effects of deer play of Wu Qin Xi on cervical mobility, TCM symptoms and anxiety in elderly patients with cervical spondylotic radiculopathy. Methods Sixty patients with orthopaedic inpatients from June 2017 to June 2018 were enrolled. In the 6 to December 2017, 30 inpatients who met the criteria were selected as the control group, and 30 patients who met the criteria from January to June 20 were the intervention group. Two groups of patients were treated with conventional nursing, and the intervention group was treated with deer play on the basis of the control group. Cervical dysfunction index (NDI) was compared before intervention, 2 weeks and 4 weeks after intervention; clinical symptoms and signs and neck activity were compared before intervention and 2 weeks after intervention; anxiety scores were compared before intervention and after 4 weeks of intervention ( GAD-7). Results The NDI scores of the intervention group were 19.23±2.19 and 9.23± 1.85 at 2 and 4 weeks respectively. The scores of the control group were 21.37 ± 1.40 and 11.63 ± 2.95, respectively. The difference was statistically significant (t=3.77-4.49, P<0.05). After 2 weeks of intervention, the clinical symptoms and signs and neck activity of the intervention group were 5.47±1.78, 19.17±1.26, 4.87±0.78, 11.50±1.46, the control group were 7.40±2.53, 16.23±1.87, 6.17±1.26, 13.17± 1.56, and the difference between the two groups was statistically significant (t=-7.12-4.81, P<0.05). After 4 weeks of intervention, the GAD-7 score of the intervention group was 1.07±0.20, and the control group was 1.56 ± 0.29. The difference between the two groups was statistically significant (t=6.55, P<0.05).

Recurrence of Helicobacter pylori infection and its influencing factors / 西安交通大学学报(医学版)

Objective: The recurrence of Helicobacter pylori (Hp) infection directly affects the prevention and treatment of Hp-related diseases, and the recurrence rate varies greatly in different countries and regions. We conducted this study to determine the recurrence rate of Hp infection and its influencing factors in Xi'an. Methods: We enrolled 497 patients receiving successful Hp eradication in the follow-up study. One year after the eradication therapy, 13C-urea breath test (UBT) was performed to calculate its recurrence rate. Meanwhile, a questionnaire survey was performed to analyze the factors affecting the recurrence. Results: ① A total of 422 patients completed 13C-UBT. Among them, 12 patients had recurrence of Hp infection, with an annual recurrence rate of 2.84% (95% CI 1.25%-4.42%). ② Univariate analysis showed that the type of disease, income, hygienic conditions of restaurants, contact with individuals having Hp infection and hospitalization were related to Hp recurrence (P<0.05). ③ Multivariate analysis revealed that low income (OR=3.06, 95% CI 1.24-12.76, P=0.028), poor hygienic conditions of restaurants (OR=9.16, 95% CI 2.65-32.64, P=0.039), contact with individuals having Hp infection (OR=4.27, 95% CI 1.96-13.92, P=0.034) were independent risk factors of Hp recurrence. Conclusion: The recurrence rate of Hp infection in Xi'an is low. Low income, poor hygienic conditions of restaurants and contact with individuals infected with Hp are risk factors for the recurrence.
