OBJECTIVE: To investigate the risk factors for cow's milk protein allergy (CMPA) among infants through a multicenter clinical study. METHODS: A total of 1 829 infants, aged 1-12 months, who attended the outpatient service of the pediatric department in six hospitals in Shenzhen, China from June 2016 to May 2017 were enrolled as subjects. A questionnaire survey was performed to screen out suspected cases of CMPA. Food avoidance and oral food challenge tests were used to make a confirmed diagnosis of CMPA CMPA. A multivariate logistic regression analysis was used to investigate the risk factors for CMPA. RESULTS: Among the 1 829 infants, 82 (4.48%) were diagnosed with CMPA. The multivariate logistic regression analysis showed that maternal food allergy (OR=4.91, 95%CI: 2.24-10.76, P<0.05), antibiotic exposure during pregnancy (OR=3.18, 95%CI: 1.32-7.65, P<0.05), and the introduction of complementary food at an age of <4 months (OR=3.55, 95%CI: 1.52-8.27, P<0.05) were risk factors for CMPA, while exclusive breastfeeding (OR=0.21, 95%CI: 0.08-0.58, P<0.05) and the introduction of complementary food at an age of >6 months (OR=0.38, 95%CI: 0.17-0.86, P<0.05) were protective factors. CONCLUSIONS The introduction of complementary food at an age of <4 months, maternal food allergy, and antibiotic exposure during pregnancy are risk factors for CMPA in infants.

OBJECTIVE: To compare the therapeutic effect of thunder-fire moxibustion combined with vibration training and simple vibration training on low back pain of primary osteoporosis by 's modulus of ultrasonic wave, and seek an objective evaluating method. METHODS: A total of 60 patients were randomized into an observation group and a control group, 30 cases in each one. The patients in the two groups were treated with vibration training using whole body vibration treatment bed. In the observation group, thunder-fire moxibustion was applied at Yaoyangguan (GV 3), Mingmen (GV 4), Ganshu (BL 18), Shenshu (BL 23) and Dachangshu (BL 25). The treatment was given once every other day, 3 times a week for 4 weeks. The visual analogue score (VAS), real-time shear wave elastography (RTSWE) and medical outcomes study 36-item short-form hearth survey (SF-36) were used to evaluate pain intensity, multifidus muscle tone ('s modulus) and quality of life before treatment, after 4-week treatment and 1 month after treatment. RESULTS: Compared before treatment, the VAS scores, 's modulus of multifidus muscle and 5 dimensions of SF-36 (physical condition, body pain, general health, social function and mental health) after 4-week treatment and 1 month after treatment were significantly improved in the two groups (all <0.05), the physiological role in the observation group after 4-week treatment and 1 month after treatment were improved (both <0.05). In the observation group, the VAS scores, 's modulus of multifidus muscle and 3 dimensions of SF-36 (physiological role, body pain and general health) after 4-week treatment and 1 month after treatment were superior to the control group (all <0.05). CONCLUSION The therapeutic effect of thunder-fire moxibustion combined with vibration training is superior to simple vibration training in relieving low back pain intensity and multifidus muscle tone, and improving quality of life for primary osteoporosis. RTSWE technique can be an objective examination method to evaluate pain.

Objective: To investigate the histopathologic, immunohistochemical, molecular genetic characteristics of dedifferentiated liposarcomas with meningothelial-like whorls(DDLMW). Methods: Six cases of DDLMW diagnosed at Jiangsu Province Hospital(the First Affiliated Hospital of Nanjing Medical University) from March 2012 to August 2018 were enrolled. The cases were analyzed by routine HE staining, immunohistochemistry(MDM2, CDK4 and p16) and fluorescent in-situ hybridization(FISH) on MDM2 gene. Related literatures were also reviewed. Results: Three of the 6 patients were male.The patient ages ranged from 40 to 77 years (mean, 58 years). Four tumors occurred in the retroperitoneum and two in the mediastinum. Histologically, the tumors showed, in addition to foci of well-differentied liposarcoma, characteristic, scattered meningothelial-like concentrical whorls. The whorls were composed of tightly, concentrically arranged, spindle to ovoid cells with mild to mederate cytological atypia. Metaplastic bone was present within or in their immediate vicinity in four case. The tumors cell also showed strong and diffuse immunoreactivity to MDM2, CDK4 and p16, but no immunoreactivity to S-100 protein, SMA, SOX10, EMA, CD21, CD23 or CD35. The Ki-67 labeling indexes were low, while FISH showed high levels of MDM2 amplification in all cases. Conclusions DDLMW is a rare morphologic variant of dedifferentiated liposarcoma. The whorls in DDLMW do not represent perineurial or follicular dendritic differentiation. Recognition and familiarity with its existence, as well as combined application of immunohistochemical staining and MDM FISH, are important to avoid confusion with other lesions.

Objective To evaluate the clinical effect of electromagnetic navigation system to locate the distal locking screw of tibia intramedullary nail. Methods From February 2010 to December 2016, 79 cases of tibia shaft fractures requiring treatment with intramedullary nailing were selected and divided into the navigation group and free hand locking group according to intramedullary nail locking methods. Forty-four cases in navigation group used an electromagnetic navigation system to lock the distal end of the intramedullary nail,while 35 cases in free hand locking group used a free-hand technique. The intraoperative X-ray exposure time,distal locking time,healing time, and the success rate of one-time distal locking were recorded compared between two groups. Results The average time of diatal locking using electromagnetic navigation technology was less than that of the free hand locking group,and the exposure time of fluoroscopy was also reduced, the differences were significant(P ＜ 0. 05). There was no difference in fracture healing time between the two groups(P ＞ 0. 05), one-time success rate of navigation group was 100％,which was higher than 37. 34％ of the free hand locking group, the difference was significant(P ＜ 0. 05). Conclusion Compared with free hand technology, the advantage of using electromagnetic navigation system to lock the distal nail of tibia intramedullary nail is high efficiency, short locking time and no radiation.

Objective To investigate the activities of infraspinatus (IS) and posterior deltoid (PD) under shoulder external rotation at open kinetic chain (OKC) and closed kinetic chain (CKC) exercise with shoulder abduction 0° and 90° to determine the optimal external rotation rehabilitation exercise.Methods From April to June, 2018, 19 healthy adults finished the movement of 0° OKC, 0° CKC, 90° OKC and 90°CKC. The root mean square (RMS) of IS and PD was recorded with surface electromyography (sEMG), then the standardized RMS (RMS％), ratio of IS/PD and onset time of activation were calculated.Results RMS％ of PD was the minimal at 90° CKC, and was less than that of 0° CKC (P ＜ 0.05). IS/PD was the most at90° CKC, and was more than that of 90° OKC (P ＜ 0.05). The onset time of IS was the earliest in 90° CKC, and earlier than that of 90° OKC (P ＜ 0.05) and 0°OKC (P ＜ 0.05). The onset time of PD was the latest in 0° CKC, and latter than that of 90° OKC (P ＜ 0.05).Conclusion 90°CKC activates IS mostly and earliest, which can be used in early rehabilitation for rotator cuff injury.

Objective:To observe whether the effect of electroacupuncture (EA) on improving sex hormone disorders and follicle development is by decreasing the expression of anti-Mullerian hormone (AMH) in rats with experimental polycystic ovarian syndrome (PCOS).Methods:Forty rats were randomly divided into four groups,a normal group (NG),a model group (MG),an EA at acupoints group (EAAG),and an EA at non-acupoints group (EANAG),with 10 rats in each group.The rats in the EAAG and EANAG were intervened by EA treatment for consecutive 14 d.Zhongji (CV 3) and Guanyuan (CV 4) were selected as the acupoints in the EAAG,and the tip of the tail and 1 cm up from the tail tip were selected as the non-acupoints in the EANAG.After treatment,the histomorphological changes of the ovary,the levels of aromatase P450 (P450arom),testosterone and estradiol in the ovarian tissues,and the expressions of follicle stimulating hormone (FSH) and AMH were observed.Results:After treatment,compared with the MG and EANAG,the expression of AMH decreased (P＜0.05),the levels of P450arom and estradiol increased significantly,and the level of testosterone decreased significantly (all P＜0.01) in the EAAG.Additionally,several normal follicles were present and the number of cystically dilated follicles decreased in the EAAG.Compared with the MG and EANAG,the EAAG obviously had more follicular granulosa cells.Conclusion:EA can down-regulate the abnormally increased expression of AMH to improve sex hormone disorders and follicle development in PCOS rats.

Objective    To describe the effect of sequential pulmonary balloon angioplasty for patients with chronic thromboembolic pulmonary hypertension, who was accompanied with progressed pulmonary hypertension after pulmonary endarterectomy surgeries. Methods    From 2014 to December 2017, 7 patients were treated with a combination therapy of pulmonary endarterectomy and sequential pulmonary balloon angioplasty. There were 1 male and 6 females at age of 58 (43–59) years. A follow-up period of more than 1 year was accomplished. The result of right sided heart catheterization and ultrasonic cardiogram between and after the pulmonary endarterectomy or balloon angioplasty was collected. Results    Seven patients were treated with a combination of pulmonary endarterectomy and sequential pulmonary balloon angioplasty, which included 1 patient of single pulmonary balloon angioplasty and 6 patients of multiple pulmonary balloon angioplasties. The balloon dilation times was 2 (2–6), and the number of segments during each single balloon dilatation was 3–5, compared with the first clinical results before  the first balloon dilation, systolic pulmonary artery pressure [53 (47–75) mm Hg vs. 45 (40–54) mm Hg, P=0.042), mean pulmonaryartery pressure [38 (29–47) mm Hg vs. 29 (25–39) mm Hg, P=0.043], N terminal-B type natriuretic peptide [1 872 (1 598–2 898) pg/ml vs. 164 (72–334) pg/ml, P=0.018] improved significantly after the last balloon angioplasty. Heart function classification (NYHA) of all the 7 patients were recovered to Ⅰ-Ⅱclasses (P<0.05). Conclusion    Sequential pulmonary balloon angioplasty after pulmonary endarterectomy can further reduce the patient's right heart after load, improve the heart function for patients with progressed pulmonary hypertension after pulmonary endarterectomy surgeries.

OBJECTIVE: To observe the correlation between referred pain distribution and acupoint sensitization in patients with intestinal diseases. METHODS: In clinical research, 443 patients from 8 hospitals were recruited, including the outpatients and inpatients of Crohn's disease (=143), ulcerative colitis (=108), chronic appendicitis (=87) and other intestinal diseases (=105). The site with tenderness on the body surface and the morphological changes of local skin were observed and recorded in the patients. Using a sensory tenderness instrument, the pain threshold at the sensitization point was measured in 60 patients with ulcerative colitis. In animal experiment, SD rats were used and divided into a enteritis group (=8), in which the enteritis model were established, and a control group (=3), in which no any intervention was given. After the injection of Evans blue (EB) at caudal vein, the blue exudation points on the body surface were observed and the distribution rule was analyzed statistically. RESULTS: The referred pain on the body surface in the patients with intestinal diseases was mainly located in the lower abdomen (93.9%, 416/443), the lumbar region (70.9%, 314/443) and the lower legs (33.0%, 146/443). The diameter of tenderness region was 1.5 to 2.5 cm. Compared with the region without sensitization, the pain threshold of the sensitization point in the patients with ulcerative colitis was reduced significantly (<0.001). The referred pain on the body surface in the patients with appendicitis was located in the right lower abdomen (97.7%, 85/87), the waist and back (54.0%, 47/87) and the right lower limbs on the medial side (71.3%, 62/87). The tenderness region was 1 to 2 cm in diameter and was irregular in form. After modeling of enteritis in the rats, the EB exudation points were visible from T to L. CONCLUSION Intestinal diseases induce referred pain on the body surface where is the same as or adjacent to the location of the spinal segment corresponding to the affected intestinal section. These sensitization regions are related to the locations of acupoints.

OBJECTIVE: To explore the clinical therapeutic effect and mechanism of acupuncture on headache in the recovery phase of ischemic stroke. METHODS: A total of 97 patients with headache in the recovery phase of ischemic stroke were randomized into an acupuncture group (57 cases) and a western medication group (40 cases). In the western medication group, flunarizine hydrochloride capsule was taken orally 5 mg each time, once a day. In the acupuncture group, acupuncture was applied at Qiuxu (GB 40), Zulinqi (GB 41), Xuanli (GB 6), Shuaigu (GB 8), Fengchi (GB 20) and Baihui (GV 20) for migraine; Chongyang (ST 42), Neiting (ST 44), Jiexi (ST 41), Zusanli (ST 36), Hegu (LI 4), Cuanzhu (BL 2) and Baihui (GV 20) for forehead pain; Jinggu (BL 64), Kunlun (BL 60), Tianzhu (BL 10), Fengchi (GB 20), Baihui (GV 20) and Sishencong (EX-HN 1) for occipital headache; Taichong (LR 3), Yongquan (KI 1), Sanyinjiao (SP 6), Fengchi (GB 20), Baihui (GV 20) and Sishencong (EX-HN 1) for parietal headache. The needles were retained for 30 min each time, once a day and 5 times a week. Both of the two groups were given consecutive treatment for 14 days. The visual analogue scale (VAS) and the headache scores before and after treatment and the recurrence rate 1 month after treatment were observed to evaluate the therapeutic effect, before and after treatment, the contents of substance P (SP), dopamine (DA), serotonin (5-HT), alpha-endorphin (α-EP) and beta-endorphin (β-EP) in plasma were determined by ELISA in the two groups. RESULTS: Compared before treatment, the VAS scores, the headache scores and the contents of SP, DA and 5-HT in plasma were reduced and the contents ofα-EP andβ-EP in plasma were increased in the two groups (all <0.01). After treatment, the changes of the VAS score, the headache score and the contents of pain-related factors and endogenous opioid peptides in plasma in the acupuncture group were larger than the western medication group (all <0.05). The total effective rate in the acupuncture group was 84.2% (48/57), which was superior to 62.5% (25/40) in the western medication group, and the recurrence rate in the acupuncture group was lower than the western medication group (both <0.01). CONCLUSION The therapeutic effect of acupuncture on headache in the recovery phase of ischemic stroke is superior to flunarizine hydrochloride capsule, and the mechanism may relate to down-regulate the pain-related factors and up-regulate endogenous opioid peptides in plasma.
