Objective: To investigate the spontaneous nystagmus (SN) and the frequency characteristics of affected semicircular canals in patients with vestibular neuritis (VN). Methods: This is a cross-sectional study. A total of 61 patients with VN admitted to the Department of Neurology of Shanxi Bethune Hospital from June 2020 to October 2021, 39 were male and 22 were female, with a mean age of (46±13) years old and male to female ratio of 1.77∶1. According to SN characteristics, 61 patients were divided into non-nystagmus group(nSN), horizontal nystagmus group(hSN) and horizontal-torsional nystagmus group (htSN). Clinical data were collected, and SN, unilateral weakness (UW), directional preponderance (DP), and video head impulse test (vHIT) gain were used as observation indicators. Statistical analysis by SPSS23.0 software. Normal distributed quantitative data (age, semicircular canal gain, SN intensity) were expressed by x¯±s, non-normal distributed quantitative data (disease course, UW, DP) were expressed by M(Q1,Q3), qualitative data were expressed by rate and composition ratio, difference analysis by one-way ANOVA, rank sum test, Chi-square test or Fisher's exact probability method, considered by P value<0.05. Results: (1)The disease course of nSN, hSN and htSN was 7.0 (4.0, 12.5), 6.0 (3.5, 11.5), and 3.0 (2.0, 6.5) days respectively, and there were statistical differences (χ2=7.31,P=0.026).(2)The horizontal nystagmus intensity of htSN was (16.8±8.6)°/s, which was significantly higher than that of (9.8±4.7)°/s in hSN (t=3.71, P<0.001). There was no significant difference in the positive rate of UW between the three groups (P=0.690), and there was a significant difference in the positive rate of DP in the three groups (χ2=12.23, P=0.002). The horizontal nystagmor intensity in the htSN was positively correlated with the vertical nystagmus intensity (r=0.59, P=0.001).(3)The gain of the affected horizontal canal of the three groups was statistically different (F=8.28, P=0.001), and the gain of the horizontal canal of hSN and htSN was significantly lower than that of nSN (t=2.74, P=0.008; t=4.05, P<0.001); The gain of the affected anterior canal in the three groups was statistically different (F=5.32, P=0.008). The gain of the anterior canal in both nSN and hSN was significantly higher than that in htSN (t=3.09, P=0.003; t=2.15, P=0.036). The horizontal canal gain of htSN is positively correlated with the anterior canal gain (r=0.74, P<0.001).(4)The affected semicircular canals in the two groups with no-vertical-component nystagmus (nSN and hSN) and the htSN were counted. The composition ratio of the affected semicircular canals in the two groups was different (χ2=8.34, P=0.015). Conclusion: The occurrence of SN in patients with VN is related to many factors, such as the disease course, low and high frequencies, and the severity of the condition in the affected semicircular canal.

The present study collected data on traditional Chinese medicine(TCM) compounds effective in relieving pain from the patent database of the State Intellectual Property Office(SIPO), sorted out the TCM compounds against pain in patents, and analyzed the medication rules to provide references for the research and development of new TCM drugs against pain. The data were subjected to frequency statistics, association rules, cluster analysis, and complex network analysis by IBM SPSS Modeler 18.3 and SPSS Statistical 26.0. The results showed that among the 101 oral prescriptions included in the statistics, the top 5 drugs were Glycyrrhizae Radix et Rhizoma, Angelicae Sinensis Radix, Paeoniae Radix Alba, Chuanxiong Rhizoma, and Salviae Miltiorrhizae Radix et Rhizoma, and among the 49 external prescriptions included in the statistics, the top 5 drugs were Myrrha, Olibanum, Angelicae Dahuricae Radix, Borneolum Syntheticum, and Chuanxiong Rhizoma. Whether oral or external prescriptions, the drugs were mainly warm in nature, and bitter, pungent, and sweet in flavor. According to TCM complex network analysis, the core drugs were Glycyrrhizae Radix et Rhizoma, Angelicae Sinensis Radix, Paeoniae Radix Alba, and Chuanxiong Rhizoma in oral prescriptions, and Olibanum, Myrrha, Glycyrrhizae Radix et Rhizoma, Chuanxiong Rhizoma, and Angelicae Sinensis Radix in external prescriptions. Overall, the therapeutic principles of oral prescriptions were mainly replenishing Qi, nourishing blood, and promoting Qi and blood circulation, while those of external prescriptions were activating blood, resolving stasis, promoting Qi flow, and relieving pain on the basis of the oral prescriptions. In the future research and development of TCM compounds against pain, the prescriptions should be modified with mind-tranquilizing and depression-relieving drugs. With the modernization of TCM, the development of new pain-relieving TCM compound patents based on ancient methods and clinical experience adhering to the guidance of TCM treatment based on syndrome differentiation can meet the new demand for pain treatment in the current society and give full play to the advantages of TCM in pain treatment.

Objective: This study aims to investigate the sleep quality of pregnant women in Xuhui District, Shanghai, and the related factors of sleep disturbances during pregnancy. Methods: From February 2019 to February 2021, we used online integrated sleep questionnaire (including PSQI, BQ, ESS, AIS) in Shanghai Jiao Tong University School of Medicine Affiliated Sixth People's Hospital, The International Peace Maternity and Child Health Hospitals of China Welfare Institution, and Shanghai Eighth People's Hospital, to investigate the sleep quality across pregnancy. We also collected maternal physical examination results, childbearing history, sociodemographic, and other clinical data. The prevalences and related factors of various sleep disturbances in pregnant women were analyzed, including insufficient/excessive nighttime sleep, low sleep efficiency, difficulty falling asleep, poor sleep quality, insomnia, daytime sleepiness, and high risk of sleep-disordered breathing (SDB). Results: This study includes 1 898 cases in the first trimester (T1), 3 099 cases in the second trimester (T2), and 1 539 cases in the third trimester (T3). Poor sleep quality (38.6%), daytime sleepiness (mild 41.9%, moderate 17.7%, severe 2.1%), and suspicious insomnia (32.3%) are most prevalent among women in T1 (P<0.01). In comparison, short sleep time (2.7%), long sleep time (8.6%), difficulty falling asleep (12.2%), poor sleep efficiency (35.4%), very poor sleep quality (6.7%), clinical insomnia (21.8%), and high-risk SDB (6.4%) are most prevalent among women in T3 (P<0.05). During pregnancy, late gestation (OR=1.016, 95%CI: 1.006-1.025) and multiple induced/drug abortions (OR=1.329, 95%CI: 1.043-1.692) are risk factors for poor sleep quality (PSQI>5), while multiple full-term deliveries (OR=0.800, 95%CI: 0.675-0.949) is its protective factor. Advanced maternal age (OR=0.976, 95%CI: 0.956-0.997), multiple full-term deliveries (OR=0.808, 95%CI: 0.680-0.959), late gestation (OR=0.983, 95%CI: 0.974-0.992) and hypertension (OR=0.572, 95%CI: 0.401-0.814) are protective factors for daytime sleepiness (ESS>6). The high-risk pregnancy category (OR=9.312, 95%CI: 1.156-74.978) is a risk factor for insomnia (AIS≥4), while multiple full-term deliveries (OR=0.815, 95%CI: 0.691-0.961) is its protective factor. High BMI (OR=1.334, 95%CI: 1.270-1.402) and hypertension (OR=4.427, 95%CI: 2.539-7.719) are risk factors for high-risk SDB in pregnant women. Conclusions: The prevalences of various sleep disturbances are high throughout pregnancy. Noticeably, symptoms of maternal SDB develop along with pregnancy. Different types of sleep disturbances are associated with different factors. Women of high-risk pregnancy category, in late gestation, with high BMI, hypertension, a history of induced/drug abortion, or without a history of full-term delivery can be at high risk of sleep disturbances during pregnancy.

Objective: To compare the therapeutic efficacy of Han-uvulopalatopharyngoplasty (HUPPP) combined with radiofrequency ablation of tongue base or HUPPP with traction of tongue base on moderate to severe patients with obstructive sleep apnea hypopnea syndrome (OSAHS). Methods: This is a multicenter randomized controlled trial. From March 2017 to July 2019, moderate to severe OSAHS patients from three clinical center in Shanghai who were intolerant to continuous positive airway pressure (CPAP) and with velopharyngeal and glossopharyngeal plane obstruction were enrolled in this study. According to the surgical type, they were 1∶1 randomized to HUPPP plus radiofrequency ablation of tongue base group (Ablation group) or HUPPP plus traction of tongue base group (Traction group). All patients completed over-night standard Polysomnography (PSG), upper-airway assessment (Friedman classification, Müller test, CT and cephalometric examination), preoperative routine examination, Epworth Sleepiness Scale (ESS) and Quebec sleep questionnaire (QSQ). Six to 12 months after operation, all the above-mentioned examinations were repeatedly performed. Changes of aforementioned variables before and after operation were assessed. Results: A total of 43 patients with moderate to severe OSAHS were enrolled in this study. One patient lost to follow-up, the remaining 21 were allocated to Ablation group and 21 were allocated to Traction group. The total therapeutic efficacy of all patients was 69.05% (61.90% in Ablation group and 76.19% in Traction group), but there was no statistical significance between the two groups (P= 0.317). The value of sleep scale score (ESS and QSQ), objective sleep variables (apnea-hypopnea index, oxygen saturation, percentage of time with blood oxygen less than 90% in total sleep time, oxygen desaturation index and micro-arousals) and upper airway cross-sectional area (palatopharyngeal and retrolingual area) of the two groups were improved (P<0.05), but the differences between the two groups were not statistically significant (P>0.05). Conclusion: For moderate to severe OSAHS who had glossopharyngeal plane obstruction, both HUPPP plus radiofrequency ablation of tongue base or HUPPP plus traction of tongue base are effective treatment for OSAHS, and the curative effect is similar. The choice of surgical type could be selected according to patient's or surgical conditions.

Objective::To investigate the effects of modified Buwangsan on the learning and memory ability of Alzheimer's disease (AD) model rats and the expression of NOD-like receptor 3 (NLRP3), cysteine-containing aspartate-specific proteases 1 (Caspase-1) and interleukin-1 beta (IL-1β) in NLRP3 inflammatory pathway in hippocampus of AD model rats, and exploring the underlying mechanism of modified Buwangsan. Method::The 52 eligible rats were randomly divided into sham control group, AD model group, low-dose modified Buwangsan group (1.5 g·kg-1) and high-dose modified Buwangsan group (3 g·kg-1). AD mouse model was established by bilateral hippocampus injection of Aβ1-425 μL (2 g·L-1). The rats in low-dose and high-dose modified Buwangsan group received low and high dose modified Buwangsan respectively within the next 4 weeks, once daily. The learning and memory ability was tested by Morris water maze. The expression of NLRP3, Caspase-1 and IL-1β mRNA was tested by quantitative PCR(Real-time PCR) and Western blot. Result::As compared with the sham group, the learning and memory ability of the rats were significantly impaired (P<0.05). Compared with AD model group, the learning and memory ability and the expression levels of NLRP3, Caspase-1, and IL-1β mRNA and protein were all no statistical differences in low-dose modified Buwangsan group, while the learning and memory ability of the rats were significantly improved and the expression of NLRP3, Caspase-1 and IL-1β mRNA in hippocampus of rats was significantly decreased in high-dose modified Buwangsan group (P<0.05). Conclusion::High-dose modified Buwangsan could attenuate neuroinflammation in the hippocampus of AD mouse model via inhibiting the expression of NLRP3, Caspase-1 and IL-1β, which may be the mechanisms of modified Buwangsan could be used to ameliorate the learning and memory ability of AD mouse model.
摘要
The classification of chronic pain is complex and its pathogenesis is not clear, which led to the limited progress of treatment measures.Traditional Chinese medicine(TCM) has certain advantages in the treatment of chronic pain, and its mechanism needs further exploration. The ideal animal model is helpful to elucidate the key mechanism of the occurrence and development of chronic pain and play an important role in the discovery of new drug targets, the development of new therapies and the research on the analgesic mechanism of TCM.In recent years, many scholars at home and abroad have done a lot of research to explore the pathogenesis of chronic pain and the mechanism of TCM, which have achieved some results. On this basis, this study summarizes the selection of experimental animals for chronic pain and the commonly evaluation methods of animal models. According to the latest international classification of diseases, this review organizes the induced methods, evaluation indicators, advantages and disadvantages of seven kinds of chronic pain animal models, such as chronic primary pain, chronic cancer-related pain and so on. Next, this review introduces the chronic pain animal models commonly used in TCM research, in order to provide guidance for the targeted selection of animal models when carrying out relevant experiments in the future.

BACKGROUND@#B-cell activating factor (BAFF) is vital for B cell survival. Serum BAFF levels are elevated in thrombotic antiphospholipid syndrome, but little is known about levels in patients with positive antiphospholipid antibodies (aPLs) and previous adverse pregnancy outcomes (APOs). We aimed to analyze serum BAFF concentrations of these patients in early pregnancy along with different pregnancy outcomes.@*METHODS@#Thirty-six pregnant patients positive for aPLs and previous APOs (patient group), 25 healthy pregnant females (HP group) and 35 healthy non-pregnant females (HNP group) from the Peking University Third Hospital, between October 2018 and March 2019, were enrolled in this study. Serum of HNP and serum of patients as well as HP in the first gestational trimester were collected. Enzyme-linked immunosorbent assay kits were used to measure serum BAFF and interferon-alpha (IFN-α) concentrations. Cytometric bead array analysis was used to measure serum concentrations of cytokines. The patient group was further divided into APOs and non-APOs (NAPOs) group, fetal loss and live birth group according to pregnancy outcomes. The Mann-Whitney U-test was used to assess significance between and within groups. Spearman rank-order was used to evaluate correlation coefficients between BAFF and related cytokines.@*RESULTS@#The serum BAFF level in HP group was significantly lower than HNP group (245.24 [218.80, 265.90] vs. 326.94 [267.31, 414.80] pg/mL, Z = -3.966, P < 0.001). The BAFF level was obviously elevated in patient group compared to that in HP group (307.77 [219.86, 415.65] vs. 245.24 [218.80, 265.90] pg/mL, Z = -2.464, P = 0.013). BAFF levels in APOs group tended to be higher than that in NAPOs group (416.52 [307.07, 511.12] vs. 259.37 [203.59, 375.81] pg/mL, Z = -2.718, P = 0.006). Compared to HP group, concentrations of IFN-α, interleukin (IL-6) and tumor necrosis factor were higher in patient group (33.37 [18.85, 48.12] vs. 13.10 [6.85, 25.47] pg/mL, Z = -2.023, P = 0.043; 39.16 [4.41, 195.87] vs. 3.37 [2.92, 3.90] pg/mL, Z = -3.650, P < 0.001; 8.23 [2.27, 64.46] vs. 1.53 [1.25, 2.31] pg/mL, Z = -3.604, P < 0.001, respectively). Serum BAFF levels had a positive correlation with the concentrations of both IL-6 and IL-10 (IL-6: r = 0.525, P = 0.002; IL-10: r = 0.438, P = 0.012).@*CONCLUSIONS@#Serum BAFF levels are increased in patients with positive aPLs and previous APOs as compared to healthy pregnant females and tend to be higher in individuals with current APOs. The BAFF levels have a positive correlation with serum IL-6 and IL-10.
摘要
The chemokine-like factor (CKLF)-like MARVEL transmembrane domain-containing family (CMTM) is widely expressed in the immune system. Abnormal expression of CMTM is associated with the development of various diseases. This article summarizes the relevant research on the role of the CMTM family in immune disorders. This information will increase our understanding of pathogenesis and identify promising targets for the diagnosis and treatment of autoimmune diseases. The CMTM family is highly expressed in peripheral blood mononuclear cells. CKLF1 may be involved in the development of arthritis through its interaction with C-C chemokine receptor 4. CKLF1 is associated with the pathogenesis of lupus nephritis and psoriasis. Both CMTM4 and CMTM5 are associated with the pathogenesis of systemic lupus erythematosus. CMTM1, CMTM2, CMTM3, and CMTM6 play a role in rheumatoid arthritis, systemic sclerosis, Sjögren syndrome, and anti-phospholipid syndrome, respectively. The CMTM family has been implicated in various autoimmune diseases. Further research on the mechanism of the action of CMTM family members may lead to the development of new treatment strategies for autoimmune diseases.

The aim of the present study was to investigate the effect of lipoxin A4 (LXA4)pretreatment on cognitive function of aged rats after global cerebral ischemia reperfusion,and to explore its possible mechanism.Thirty-six aged male Sprague-Dawley rats were randomly divided into three groups (n=12 each):sham-operation group (S group),global cerebral ischemia reperfusion group (I/R group) and LXA4-pretreatment group (L group).The rat model of global cerebral ischemia reperfusion was established by occlusion of the bilateral common carotid artery with hypotension.The cognitive function of rats was determined by a step-down type passive avoidance test and Morris Water Maze test on the third day after reperfusion.Rats were sacrificed after Water Maze test and the pathological changes ofhippocampal CA1 region were observed and the related inflammatory mediators were determined.As compared with S group,the escape latency in I/R group was prolonged from the first day to the fifth day,while that in L group was prolonged from the first day to the third day.The retention time in I/R group and L group in the first quadrant was shortened.The reaction time,frequency of reaction mistake and frequency of escape mistake in I/R group increased,and the latent period shortened.The frequency of escape mistake in L group increased,and the damage in the hippocampal CA1 region of I/R group and L group was obvious.The levels of S-100β,TNF-α,IL-lβ,IL-10 and NF-κB in I/R group and L group increased.As compared with I/R group,the escape latency in L group was shortened from the first day to the fifth day,and the retention time in the first quadrant prolonged.The reaction time,frequency of reaction mistake and frequency of escape mistake in L group decreased,and the latent period prolonged.The damage in the hippocampal CA1 region of L group was alleviated as well.The levels of S-100β,TNF-α,IL-1β and NF-κB in L group decreased,and those of IL-10 increased.It can be concluded that LXA4 pretreatment can improve the cognitive function in aged rats after global cerebral ischemia reperfusion probably by inhibiting the inflammatory reaction.

摘要
Recurrent spontaneous abortion is one of the common complications in women of childbearing age during pregnancy. The immune factor accounts for a large proportion of many causes. Antiphospholipid antibody syndrome is the most common type of acquired thrombophilia disease. Autoimmune diseases that cause thrombosis and obstetric complications under the action of antibodies are also the most common type of immune-related recurrent abortion. At present, there is no unified opinion on the treatment of this disease, especially the treatment of immunoglobulins and other drugs like glucocorticoid. Here we reviewed the progress of diagnosis and treatment of antiphospholipid antibody-related recurrent abortions and retrospectively analyzed and summarized the drug regimens and pregnancy outcomes of this disease with pregnancy patients in our hospital. A total of 75 patients were included. According to their clinical manifestations and laboratory results, these patients were basically divided into two categories: classical antiphospholipid syndrome and non-classical antiphospholipid syndrome. The latter was further divided into serum-negative antiphospholipid syndrome and antiphospholipid antibody-related recurrent abortion patients based on their clinical manifestations and antiphospholipid antibody results. The patients were divided into four categories: aspirin + hydroxychloroquine, aspirin + low molecular weight heparin, aspirin + low molecular weight heparin + hydroxychloroquine, aspirin + hydroxychloroquine + low molecular weight heparin + low dose glucocorticoids. Among them, aspirin + hydroxychloroquine + low molecular weight heparin + low dose glucocorticoid treatment regimen was most commonly used. Most of the patients who received the above different treatment regimens achieved full-term infants, and a small number of patients had adverse pregnancy outcomes, such as premature delivery, placental abruption, eclampsia, and fetal malformation. And adverse pregnancy outcomes also occurred in this group. It might be related to the severity of the disease and the potential adverse effects of maternal fetal. However, further statistical analysis is needed for the risk factors affecting the pregnancy outcome of this part of patients.

To study the variation of six ester-type alkaloids and characteristic fingerprints in the process from Radix Aconite Lateralis to Heishunpian and lay a foundation for the study of the processing principle of Heishunpian, HPLC. analysis was performed on a Phenomenex Gemini C18 (4.6 mm x 250 mm, 5 microm) with acetonitrile and 40 mmol x L(-1) ammonium acetate (adjusted to pH 10 with concentrated ammonia water) as mobile phase. The detection wavelength was set at 235 nm. The flow rate was set at 0.8 mL x min(-1) and the injection volume was 10-20 microL. Six ester-type alkaloids were determined and characteristic fingerprints of the process were established. As the process continues, the contents of diester diterpene alkaloids were decreased step by step, while the contents varia tion of monoester diterpene alkaloids were not obvious. Each sample showed significant difference in characteristic fingerprints. With the exception of 6 known monoester diterpene alkaloids and diester diterpene alkaloids, 13 peaks were marked in the characteristic fingerprints, of which the total change rule of the other 7 unknown peaks were similar with 3 diester diterpene alkaloids. The established method is accurate, reliable and repeatable, and can provide reference for revealing change rule of index components and illuminating processing principle in the process of Heishunpian.

Different processed products of Coptidis Rhizoma have its unique odor, which is an important assessment index for pro- cessed products identification of Coptidis Rhizoma. Objectify odor as an entry point in this study, an electronic nose technology was used, and a suitable method for Coptidis Rhizoma measurement was built firstly. Then different processed products of Coptidis Rhizoma were detected by the method built. Finally, different processed products were identified by combining with chemometrics based on the objective odor information obtained. Electronic nose detection indicated that a significant difference in odor between different processed products was performed. Coptidis Rhizoma processed or not can be distinguished based on statistical quality control (SQC) and soft independent modeling of class analogy (SIMCA). Principle component analysis (PCA) model showed that Coptidis Rhizoma and its various processed products discriminated obviously. In addition, in order to identify the processed products of Coptidis Rhizoma, a correct recognition rate of 100% was acquired by discriminant factor analysis (DFA) , and the initial identification rate and cross-validation recognition rate of linear discriminant analysis (LDA) is 100%, 94.4% respectively. In conclusion, differentiationin odor of different processed Coptidis Rhizoma was performed by the electronic nose technology used, and different products Coptidis Rhizoma were dis- criminated by combining with chemometrics. This research can be a reference for objective identification in odor of traditional Chinese medicine, and is good for the inheritance and development of traditional experience in odor identification.
