Objective: To observe the clinical efficacy of tendon-regulating and bone-setting manipulation combined with endurance resistance exercises in treating female with chronic neck pain, and explore the mechanism. Methods: A total of 57 female patients with chronic neck pain who met the inclusion criteria were randomly divided into a manipulation group (29 cases) and a medium-frequency electrotherapy group (28 cases). Patients in both groups received the same endurance exercise therapy, while those in the manipulation group received additional tendon-regulating and bone-setting manipulation, and those in the medium-frequency electrotherapy group received additional medium-frequency electrotherapy. Both groups were treated for 5 weeks. Before and after treatment, the neck function of patients was evaluated by visual analog scale (VAS), Analgesy-Meter, Northwick Park questionnaire (NPQ), root mean square (RMS) and median frequency (MF) of surface electromyography of sternocleidomastoid muscle and posterior cervical extensor muscle, and the patients were followed up at a month after treatment. Results: All patients completed the treatment and were followed up. Compared with the same group before treatment, the VAS scores of both groups decreased, the tenderness values increased, the RMS and MF values increased, and the NPQ scores decreased after treatment (all P<0.05). The improvement of manipulation group was more notable than that of medium-frequency electrotherapy group (all P<0.05). At one-month follow-up, the VAS and NPQ scores of the manipulation group were lower than those before and after treatment, and the VAS and NPQ scores of the medium-frequency electrotherapy group were only lower than those before treatment; the two scores of the manipulation group were lower than those of the medium-frequency electrotherapy group (both P<0.05). Conclusion: Tendon-regulating and bone-setting manipulation combined with endurance resistance exercises can relieve neck pain and cervical dysfunction in female patients with chronic neck pain. The efficacy of this method is more durable and better than that of medium-frequency electrotherapy combined with endurance exercises.

Coronavirus disease 2019 (COVID-19) is a new infectious disease rapidly spreading around the world, raising global public health concerns. Radiological examinations play a crucial role in the early diagnosis and follow-up of COVID-19. Cross infection among patients and radiographers can occur in radiology departments due to the close and frequent contact of radiographers with confirmed or potentially infected patients in a relatively confined room during radiological workflow. This article outlines our experience in the emergency management procedure and infection control of the radiology department during the COVID-19 outbreak.

New Chemical Entities (NCEs) development is a systematic long-term project that involves multiple disciplines. The translation research will help to build an advanced R&D system from the basic laboratory research, preclinical studies and clinical evaluation to clinical application of drug, for the purpose of shortening the R&D cycle and accelerate the launch of new drugs. In new drug R&D and its clinical application, drug disposition (absorption, distribution, metabolism, excretion, ADME) properties are important criteria for assessing drug-likeness of candidates. ADME evaluation of NCEs plays an important role in the translation research throughout innovative drug R&D process. Therefore, ADME evaluation at the early stage of drug design and development will be helpful to improve the success rate and reduce costs, and further access to safe, effective drugs.

Objective To study the impact of splenectomy and esophagogastric devascularization on the nutritional status of patients with cirrhosis and portal hypertension.Methods Sixty consecutive patients with cirrhosis and portal hypertension who underwent splenectomy and esophagogastric devascularization at the Beijing YouAn Hospital from April 5,2015 to January 23,2017 were included in this study.The body mass index (BMI),albumin (Alb),prealbumin (PA) and lymphocyte counts were prospectively collected at the end of 1-week,1-month,3-month,6-month and 1-year after surgery.The postoperative results were compared with the preoperative results in these patients.Results The BMI results obtained at 1-week and 1-month after surgery were significantly lower than the preoperative level [(22.14 ± 3.08)kg/m2 vs.(22.85 ± 3.14) kg/m2,(21.72 ± 3.05) kg/m2 vs.(22.86 ± 3.16) kg/m2,P ＜ 0.05].The BMI result at the end of 1-year after surgery was significantly elevated when compared with the preoperative level [(23.24 ± 3.64) kg/m2 vs.(22.68 ± 3.47) kg/m2,P ＜ 0.05].The ALB levels at 1-month and 3-month after surgery were significantly higher than the preoperative level [(39.87 ± 4.22)g/L vs.(35.35 ±5.15) g/L,(39.35 ± 4.75) g/L vs.(34.82 ± 5.50) g/L,P ＜ 0.05].The PA obtained at 1-week after surgery was significantly lower than the preoperative levels [(79.59 26.52)mg/L vs.(121.77 ±39.96)mg/L,P ＜ 0.05].The lymphocyte counts at all the points after surgery were significantly higher than the preoperative level (P ＜ 0.05).Conclusion Short term and long term nutritional status improved in patients with cirrhosis and portal hypertension after splenectomy and esophagogastric devascularization.

OBJECTIVEGenetic factors are thought to be involved in the development of vitiligo. The aim of this study is to explore the possible genetic model of vitiligo by analyzing the genetic characteristics of 815 patients from Zhejiang province.

METHODSData for 815 patients with vitiligo together with their first- and second-degree relatives were obtained using a standardized questionnaire. All these information was requested to confirm the answers about family history in order to reduce the possibility of 'recall' bias. The 815 probands would include 411 (50.43%) males and 404 (49.57%) females with a varied age from 2 months to 71 years old. Since the information on general prevalence of vitiligo in this area was absent, a control group was set up to facilitate the calculations of heritability degree. 468 persons of the control group were from non-vitiligo population with a sex ratio of 241(male): 227(female) with varied age of 4 months to 80 years old. Both gender and age were comparable between the vitiligo and the control population. The inheritance pattern estimation, heritability calculation and complex segregation analysis were performed with Penrose method, Falconer regression method and SAGE-REGTL program.

RESULTSIn 815 vitiligo probands, 128 had and 687 had not family histories, with a heritability rate of 15.7%. The vitiligo prevalence in proband's first degree relatives was 2.580%, higher than the prevalence of 0.618% in second degree relatives, and both of them were higher than general prevalence: 0.192%. By Penrose method, the rates on different catagories were as follows: sibling prevalence rates s = 0.080 18; population prevalence rate q = 0.001 92; s/q = 41.76. The ratio of s/q did not approach 1/2q (260.42) or 1/4q (130.21), but approached 1/square root of q(22.82), suggesting vitiligo was consistent with a mode of polygenic inheritance. Using Falconer's method, heritabilities of vitiligo in first-and second degree relatives of probands were 59.61% (95% confidence interval 65.37-53.84) and 55.20% (95% confidence interval 43.88-66.52), respectively. The weighted average of heritability in all relatives was 58.7% (95% confidence interval 53.56-63.83). The results of complex segregation analysis suggested that major gene model including the Mendelian dominant, recessive and additive hypotheses were not rejected (P > 0.05). Purely environmental model and no transmission model were rejected at a 0. 001 significance level. According to AIC, Mendelian dominant inheritance was the best-fitted hypothesis.

CONCLUSIONGenetic factors played an important role in the occurrence of vitiligo, and the genetic model of vitiligo could serve as the polygenetic or multifactorial inheritance with major gene trait.

Coronavirus disease 2019 (COVID-19) is a transmissible respiratory disease that was initially reported in Wuhan, China in December 2019. With the alarming levels of COVID-19 spread worldwide, the World Health Organization characterized COVID-19 as a pandemic. Over the past several months, chest CT has played a vital role in early identification, disease severity assessment, and dynamic disease course monitoring of COVID-19. The published data has enriched our knowledge on the etiology, epidemiology, clinical manifestations, and pathologic findings of COVID-19. Additionally, as the imaging spectrum of the disease continues to be defined, extrapulmonary infections or other complications will require further attention. This review aims to provide an updated framework and essential knowledge with which radiologists can better understand COVID-19.

Objective To evaluate the effect of intensive electromyographic biofeedback ( EMGBF ) on swallowing and the velocity of hyolaryngeal excursion among stroke survivors with dysphagia. Methods Forty-two stroke survivors with dysphagia were randomly divided into a conventional rehabilitation group ( group A, n=15) , an EMGBF group (group B, n=14) and an intensive EMGBF group (group C, n=13).In addition to routine medica-tions and motor function rehabilitation training, all received 30 minutes of conventional swallowing training once a day, 5 days per week for 4 weeks. Group B additionally received 15 minutes of EMGBF once daily and group C twice daily. Videofluoroscopy was conducted to measure the superior and anterior excursion distances and the movement time of the hyoid bone when swallowing semi-liquid food, and the velocity was calculated. The swallowing dysfunction evaluation and a penetration-aspiration scale ( PAS) were also employed to evaluate the subjects'swallowing function before and after the treatment. Results There were no significant differences among the 3 groups in any of the measurements before the treatment. After the 4 weeks of treatment the average swallowing dysfunction evaluation and PAS scores of all three groups had improved significantly, as had the superior and anterior excursion velocity of the hyoid bone. Compared with group A, the average swallowing dysfunction evaluation and PAS scores of groups B and C had improved significantly more. The average swallowing dysfunction evaluation scores of groups B and C were not sig-nificantly different, but the average anterior and superior excursion velocity of the hyoid bone in group C was signifi-cantly higher than in group B. Conclusion EMGBF therapy has advantages over routine rehabilitation training in improving swallowing function after a stroke and speeding the velocity of the hyoid bone's excursions.
