Methods Interference primary screening test and interference test were conducted in BET of Shenmai Freeze-dried Powder Injection to detect whether the interference existed or not and to explore the method of removing the interference. Results There was inhibition on BET with 0.5 EU/mL tachypleus amebocyte lysate (TAL). Interference could be excluded by using 0.25 EU/mL TAL and diluting the samples. Conclusion It is feasible to use 0.25 EU/mL TAL or TAL with more sensitivity in BET of Shenmai Freeze-dried Powder Injection.

Hypoxic ischemic encephalopathy (HIE) is one of the leading causes of neonatal morbidity and mortality worldwide, and it has a series of clinical manifestations of encephalopathy.Survivors often have different degrees of neurodevelopmental impairment.In addition to supporting symptomatic treatment, hypothermia is the safest and most effective treatment for the neuroprotection and the improvement of the prognosis of neonatal HIE.However, hypothermia cannot provide complete neuroprotection and is limited by gestational age, time, and facilities and so on.Therefore, clinicians and researchers actively seek for supplements and/or alternative therapies for neonatal HIE.It was reported that stem cell transplantation has a good application prospect in the treatment of HIE.Erythropoietin and xenon and melatonin may also play neuroprotective roles in HIE.In order to provide a better theoretical basis for clinical practices, this paper reviewed the research progress of neonatal HIE treatment.

Objective To study how to reduce the incidence rate of skin flap necrosis after the eradicative resection of breast cancer. Methods 45 patients with breast cancer underwent eradicative operation with new methods to prevent the necrosis of skin flap,and they were studied and compared with 1210 cases treated by traditional ways. Results With the new methods adopted, the necrosis rate of skin flap following eradicative operation of breast cancer was reduced from 45%(original)to 2%(present).Statistic analysis showed that there was outstanding difference between them. Conclusion In the eradicative operation of breast cancer,the key to prevent the necrosis rate of skin flap is:prevention of subaxillary lymphatic fistula, two tubular drainage set individually in subcostalis and subaxillaris, appropriate force of chest bandaging, proper thickness of skin flap and perfect suture without tension.

Objective: To observe the clinical effect of moxibustion combined with Duhuo Jisheng decoction for middle-aged and elderly patients with knee osteoarthritis (KOA) and its impact on serum high sensitive C-reactive protein (hs-CRP), interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) levels. Methods: A total of 90 eligible KOA patients were randomized into an observation group (n=45) and a control group (n=45). Cases in the observation group received moxibustion plus oral administration Duhuo Jisheng decoction, while cases in the control group received Duhuo Jisheng decoction. Then the hs-CRP, IL-1β and TNF-α levels were examined and the clinical effect was evaluated. Results: Before treatment, the hs-CRP, IL-1β and TNF-α levels showed no between-group statistical differences (all P>0.05). After 8 weeks of treatment, the hs-CRP, IL-1β and TNF-α levels all dropped significantly in both groups (P<0.01 or P<0.05), and the treatment group showed more substantial changes than the control group (all P<0.05). The total effective rate was 97.8% in the treatment group, versus 86.7% in the control group, showing a statistical difference (P<0.05). Conclusion: Moxibustion plus Duhuo Jisheng decoction has a good clinical effect for middle-aged and elderly KOA patients, and the effect may relate to the decreased hs-CRP, IL-1β and TNF-α levels.

Objective To explore the cognitive status of amyotrophic lateral sclerosis (ALS) patients, and to explore the involved cognitive domains, subtypes and risk factors of mild cognitive impairment in ALS ( ALS-MCI).Methods Twenty-nine cases of ALS and 58 healthy volunteers were included.The severity of the bulbar and spinal functions of the patients was evaluated by the Improved Norris Scale.According to the Diagnostic and Statistical Manual of Mental Disorders 4th Edition-Revised( DSM-Ⅳ-R) criteria of dementia, ALS cases were classified as demented and non-demented.For non-demented ALS cases, the common cognitive batteries evaluating mental state, verbal memory, executive, attentional and visuospatial abilities were performed.Hamilton Anxiety Scale ( HAMA) and Hamilton Depression Scale (HAMD) were evaluated too.They were further classified into ALS-cognitively normal (ALS-CogNL) and ALS-MCI groups according to Petersen criteria of MCI.Risk factors possibly correlated with ALS-MCI were analyzed by comparing the differences in age, age of onset, duration of the disease, sites of onset, symptoms of bulbar and limb function between ALS-CogNL and ALS-MCI groups.Results Among 29 ALS cases, 14 (48.3% ) cases with cognitively normal( ALS-CogNL), 15 cases (51.7% ) with ALS-MCI,and none with dementia were identified.Among 15 ALS-MCI cases, 12 cases with executive dysfunction, 8 cases with memory deficits,9 cases with attention impairment and none with visuospatial impairment were found.ALSMCI cases could be further classified into three subtypes; 1 case with amnestic MCI (aMCI) ,6 cases with single domain non-memory MCI ( sdMCI), and 8 cases with multiple domains slightly impaired MCI (mdMCI).Between ALS-MCI and ALS-CogNL groups, there were significant differences (t = -2.435,- 2.576, both P ＜ 0.05) in education ((8.7 ± 2.8) years vs (11.3 ± 3.0) years) and Improved Norrisscale (bulbar score: (28.4 ± 7.7) scores vs ( 34.0 ± 3.4) scores) , however, no significant differences in sex, age, age of onset, duration,site of onset,HAMA or HAMD scores,and Improved Norris scale( spinal score) were found.Conclusions Cognitive deficits commonly exist in ALS patients.For the involved domains, executive dysfunction is the most common, deficits of attention and memory are also common, and deficit in visuospatial function is not found.The most common subtype of ALS-MCI is mdMCI.Severe bulbar symptoms and lower education may be the risk factors of ALS-MCI.

Objective:Aimed to investigate the value of adrenocorticotropic hormone (ACTH) stimulation in adrenal venous blood sampling (AVS).Methods:Patients who diagnosed as primary aldosteronism (PA) and completed successful bilateral cannulation judged by selection index (SI) for routine and(or) ACTH stimulation AVS were enrolled. The lateralization index(LI) was calculated to compare the effect of ACTH stimulation on AVS cannulation success rate and lateralization judgment.Results:A total of 73 patients with PA were enrolled in the study, of whom 28 were confirmed as aldosterone producing adenoma (APA) after unilateral adrenalectomy. Cortisol and aldosterone in peripheral and adrenal veins were significantly increased after ACTH stimulation. The left SI was increased from 6.5(3.0-13.6) to 26.8 (16.9-40.3) ( P<0.01) and the right SI from 20.8(4.8-34.8) to 57.6(35.7-80.9) ( P<0.01) after ACTH stimulation. There was no significant difference on LI before and after ACTH stimulation [7.7(2.3-19.6) vs 5.6(1.9-14.6), P=0.14]. The success rates of left and right adrenal cannulation were increased by 15% and 10% respectively after ACTH stimulation. For 57 patients who were determined in successful cannulation by both routine and ACTH stimulation AVS, 27 patients were determined to have lateralization by both AVS methods, 21 patients were determined to have bilateralization, and the consistency of lateralization by both AVS methods was 84%(48/57). Among the 28 patients who were confirmed to be APA after unilateral adrenalectomy, the correct rate of lateralization by both AVS methods was 89% (25/28). Conclusion:ACTH stimulation is able to improve the success rate of bilateral adrenal vein cannulation, and is helpful to judge AVS results. For patients with successful cannulation, there is no significant difference in lateralization judgment for routine and ACTH stimulation AVS.

OBJECTIVETo evaluate the clinical efficacy and mechanism of Feiyangqin Rectum Condensed Liquid (FRCL) in treating children syncytial viral pneumonia. Methods Seventy-two patients were randomly divided into two groups, the 36 patients in the treated group were treated with FRCL, and the other 36 patients in the control group simply treated with Western medicine. Efficacy of treatment on clinical condition and some immune function (IgA, IgG, CD3, CD4) were observed.

RESULTSIn the treated group, 28 patients were cured (77.8%), treatment was markedly effective in 4 patients (11.1%), effective in 2 (5.5%) and ineffective in 2 (5.6%), with the total effective rate of 94.4%. The corresponding number in the control group was 20 (55.6%), 7 (19.4%), 6 (16.7%), 3 (8.3%) and 91.7%, respectively. The cure rate in the treated group was obviously superior to that in the control group (P < 0.05). FRCL could improve serum IgA, IgG, CD3, CD4, and CD4/CD8, lower serum IgE, these indexes in the treated group were significantly different to those in the control group (P < 0.05).

CONCLUSIONFRCL had the action in treating children syncytial viral pneumonia without any adverse reaction, one of its mechanisms might be related to its regulation on immune function.

OBJECTIVE To investigate the clinical significance of microcalcification under high resolution ultrasonography in predicting thyroid micropapillary carcinoma(PTMC) and cervical lymph node metastasis. METHODS The clinical data of 388 patients with papi l lar y thyroid microcarcinoma were analyzed retrospectively in Beijing Tongren Hospital from Jan 2013 to Jun 2017, which included patients' clinical ultrasonographic features and pathological results in this study. Pearson correlation analysis and data fitting modeling were used to analyze the microcalcification, the maximum diameter of the tumor and the cervical lymph node metastasis in the central region. RESULTS The incidence of microcalcification in PTMC patients was closely related to the maximal diameter of the tumor. The tumor diameter of PTMC was related to the lymph node metastasis rate in the central region of the neck, and it was not found that microcalcification was associated with lymph node metastasis in the central region of the neck. CONCLUSION The weight of microcalcification in the diagnosis of PTMC is related to the maximum diameter of the nodule. Furthermore, patients with thyroid nodules having a tumor diameter of less than 1 cm, with the larger diameter of tumor nodules, the greater the risk of PTMC, the more recommended fine needle biopsy.
