Objective To observe the effect of Tangbi Capsules(TC)on ultrastructure of sciatic nerve in diabetic rats.Methods SD diabetic rat models were induced by one-dose intraperitoneal injection of streptozotocin(50 mg/kg).Then the diabetic rats were randomized into 5 groups: model group,high-and low-dose TC groups(in the dose of 1 and 0.5 g?kg-1?d-1 respectively),mecobalamin(250 ?g?kg-1?d-1)group,and the combination group(receiving TC 0.5 g?kg-1?d-1 and mecobalamin 250 ?g?kg-1?d-1).Meanwhile,the normal control group was also set up.After treatment for 4 weeks,the changes of utrastructure of sciatic nerve in different groups were observed under electron microscope.Results The pathological changes of sciatic nerve in diabetic rats were similar with the clinical peripheral neuropathy.The protective effect on sciatic nerve in high-dose TC group was superior to that in low-dose TC group and mecobalamin group,and the combination group had the best protective effect.Conclusion TC exerts certain protective effect on diabetic peripheral neuropathy.

Objective To investigate the clinical efficacy of Xinmailong on heart failure in coronary heart disease and on the levels of hs-C-reactive protein (hs-CRP)and N-terminal B-type natriuretic peptide (NT-proBNP).Methods 84 elderly patients diagnosed with heart failure in coronary heart disease were enrolled in this study at our hospital from October 2014 to October 2015.All patients were randomly divided into the control group with conventional treatment(n=42) and observation group with conventional plus Xinmailong treatment(n =42).The Lee's heart failure score,cardiac function grade,quality of life score and the changes of plasma hs-CRP and NT-proBNP after one week of therapy were compared between the two groups before versus after treatment.The adverse reactions were observed during the treatment.Results The clinical efficacy rate of heart failure after treatment was significantly higher in the observation group (83.3％,35 cases)than in control group(54.7 ％,23 cases) (x2 =8.016,P =0.033).The clinical efficacy of heart function after treatment was significantly higher in the observation group(80.9 ％,34 cases)than in the control group (59.5 ％,25 cases) (x2 =6.219,P =0.019).After treatment,the quality of life score was significantly lower in observation group (15.89 ± 3.39) than in the control group (23.80 ± 5.66) (t =7.266,P =0.026).The plasma levels of NT-proBNP and hs-CRP were significantly lower after than before treatment in NT-proBNP[(1 136.6±236.8)ng/L and (2 266.9±260.9)ng/L],and in hs-CRP[(3.06 ±0.26)mg/L and (3.56±0.29)mg/L] (t=6.608、5.106,P=0.019、0.009).There were no serious adverse reactions in both groups during the treatment.Conclusions Xinmailong can not only improve safely and effectively the quality of life of patients,but also block the atherosclerosis of the inflammatory response.

Objective With the same times of injection to compare low-dose intradermal regimen with routine-dose intramuscular inoculation in revaccination of non-responders to hepatitis B vaccine. Methods 40 healthy non-responder children collected by screening were administrated a three-dose revaccination randomly by intramuscular or intradermal route (10 vs 2 g per dose), and regularly tested for serologic markers up to five years. By the end of follow-up, a booster dose (5 μg) was given to those who had lost anti-HBs of ≥10 mIU/mL (seroprotection) and anamnestic response was estimated thereafter. Results All 17 intramuscular and 22 of 23 intradermal children effected seroprotection after revaccination. Intradermal children lost seroprotection over time significantly rapider compared with intramuscular children (Log Rank test, P= 0.029). In year 5, 50% of intramuscular but only 18.2% of intradermal children still maintained seroprotection (P=0.075). 12-14 days after the booster dose, all the eight intramuscular children developed an anamnestic response with anti-HBs titer increasing greater, but two of the 18 intradermal children failed to mount seroprotective level. Conclusion Three-routine-dose intramuscular revaccination was significantly effective than low-dose intradermal one with the same times of injection, especially in long-term immunity. We recommend routine-dose intramuscular protocol in revaccination of non-responders.

Objective:To explore the clinical effect and application value of simultaneous modulated accelerated radiotherapy (SMART) in the suspicious positive lymph nodes of head and neck.Methods:From January 2017 to February 2019, 60 patients with suspected positive lymph nodes in the head and neck in the Hanzhong Central Hospital of Shaanxi Province were divided into experimental group and control group according to different treatment plans, and 30 patients in each group were included. In the experimental group, 63.36 to 66.66 Gy patients were treated with SMART, while in the control group, 54.12 to 60.06 Gy patients were treated with conventional neck prophylactic radiation. In order to evaluate the feasibility of the method, the change of the short diameter of the largest cross section of the suspicious positive lymph nodes in the two groups were observed, and the adverse reactions in the treatment of the two groups were analyzed.Results:There was no significant difference between the two groups before treatment ( P>0.05). After treatment, the size of short diameter of lymph nodes in the two groups was smaller than that before treatment. The maximum short diameter of the largest cross section of lymph nodes in the experimental group was smaller than that before treatment: (0.43 ± 0.07) cm vs. (0.72 ± 0.10) cm, and the difference was statistically significant ( P<0.05). In the control group, the maximum short diameter of the largest cross section of lymph node decreased after treatment, and the difference was not statistically significant ( P>0.05). After treatment, the reduction of the short diameter in the experimental group was more obvious than that in the control group. The maximum short diameter of the largest cross section between the two groups: (0.43±0.07) cm vs. (0.66±0.08)cm was statistically significant ( t = 11.523, P<0.05). Before treatment, hemoglobin (HGB) levels of the two groups were in the normal physiological range, and there was no significant difference between the two groups ( P>0.05); the white blood cell (WBC) levels of the two groups at different time after treatment were compared: in the first week (7.83 ± 2.53) × 10 9/L vs. (8.26 ± 3.16) × 10 9/L, in the third week (7.14 ± 3.65) × 10 9/L vs. (7.08 ± 2.53) × 10 9/L, in the fifth week (5.47 ± 2.81) × 10 9/L vs. (6.41 ± 2.57) × 10 9/L, and in the seventh week (4.36 ± 2.59) × 10 9/L vs. (4.98 ± 1.64) × 10 9/L, and there were statistical differences ( P<0.05), which indicated that the WBC index levels of the two groups were gradually decreased during the treatment, and the decreased degree of the experimental group was higher than that of the control group. The levels of HGB and PLT were maintained in the normal physiological range before and after treatment, and there was no significant difference between the two groups ( P>0.05). The main complications in the treatment of the experimental group were xerostomia and stomatitis. The adverse reactions in the control group were pain in the target area of radiotherapy. There was no significant difference between the two groups ( P>0.05). Conclusions:The application of IMRT is an effective method for the treatment of occult lymph node metastasis, and it is also a therapeutic diagnostic method, which can provide evidence for the study of the law of lymph node metastasis in the head and neck. The safety and tissue tolerance of IMRT in the treatment of suspicious positive lymph nodes in the head and neck are good, which can be used for the suspicious lymph nodes in the head and neck. The treatment of positive lymph nodes and the evaluation of patients′ prognosis provide an effective way of clinical treatment.

Objective To evaluate the clinical value of acetic acid with narrow-band imaging ( NBI ) and magnifying endoscopy ( ME ) on diagnosis of small colorectal polyps. Methods In this prospective study, 261 small colorectal polyps from 122 patients were observed by ME, NBI-ME, and acetic acid with NBI-ME, and then received endoscopic treatment. Endoscopic images were stored electronically and randomly allocated to 3 experts and 3 non-experts for diagnosis using Kudo pit pattern. The postoperative pathologic results acted as gold standard to evaluate the diagnostic accuracy of different endoscopic modes for small colorectal polyps. The image definition and interobserver agreement were compared among different endoscopic modes. Results The diagnostic accuracy of ME, NBI-ME, and acetic acid with NBI-ME for small colorectal polyps was 65. 5％ ( 171/261) , 90. 0％ ( 235/261) , and 94. 6％ ( 247/261) , respectively, in the experts group, and 57. 1％ ( 149/261) , 83. 1％ ( 217/261) , and 89. 3％ ( 233/261) , respectively, in the non-experts group. All experts and non-experts diagnosed small colorectal polyps more accurately by acetic acid with NBI-ME than by NBI-ME ( all P<0. 05 ) and ME ( all P<0. 001 ) . The image definition scores of acetic acid with NBI-ME in the experts group and non-experts group were significantly higher than those of NBI-ME and ME ( all P<0. 001) . The results of interobserver agreement showed that Kappa values (95％CI) of ME, NBI-ME, and acetic acid with NBI-ME diagnosis were 0. 578 (0. 508-0. 648), 0. 669 (0. 599-0. 739), and 0. 940 (0. 870-1. 010), respectively, for experts and 0. 476 (0. 406-0. 546), 0. 534 ( 0. 464-0. 604) , and 0. 830 ( 0. 760-0. 900 ) , respectively, for non-experts. Acetic acid with NBI-ME showed good interobserver agreement. Conclusion Acetic acid with NBI-ME has a higher diagnostic accuracy and good reproducibility for colorectal small polyps compared with ME and NBI-ME.

Objective:To explore the clinic effects of the head of second metatarsal bone and flap for bone and skin defect at lateral malleolus in children.Methods:Between July 2009 and May 2018, 4 children with ankle bone and skin and soft tissue defects in the Jizhong Energy Xingtai Mig General Hospital were selected, including 3 boys and 1 girl aged 4-13 years old. All cases were lateral malleolus defect with adjacent skin defect, the range of skin defect was 2.0 cm×2.0 cm -4.0 cm×5.0 cm, and the range of bone defect was 1.0-3.0 cm. The area of the flap was 2.5 cm×2.5 cm-4.5 cm × 5.5 cm, and the length of the second metatarsal head was 1.0-3.0 cm. The donor site was closed directly. After the operation, X-rays was performed to evaluate whether the ankle space and lateral malleolus longitudinal development was synchronized with the uninjured limb. Ankle joint function recovery was evaluated according to the American Orthopaedic Foot and Ankle Society (AOFAS). The outcomes of donor foot range of motion, weight-bearing, and walking were observed.Results:All the composite tissue flap survived with good blood circulation, and all the donor sites healed well. All the child patients were followed up for 0.5-2.0 years. The color and elasticity of the flaps were good, without cicatricial contracture. The patients had no inversion of ankle joint, with satisfying loading and walking function. Imaging evaluation showed that the space between ankle points and the longitudinal development of lateral malleolus were roughly synchronous with the healthy side. Two cases were graded as excellent and 2 as good according to the standard of the AOFAS.The donor's foot had normal flexion and extension function, without instability.Conclusions:The head of second metatarsal bone and flap can repair the epiphysis and soft tissue defect of lateral malleolus in children at one stage, and the reconstructed lateral malleolus can develop with the growth of children. It is a satisfactory method of reconstructing the traumatic defect of lateral malleolus in children.
