ABSTRACT
Objective:To evaluate the clinical efficacy of kidney-invigorating and asthma-relieving granules in treating kidney deficiency type of bronchial asthma patients in persistent.Methods:A total of 100 patients with bronchial asthma admitted to Shanghai Municipal Hospital of TCM from March 2020 to August 2020 were selected as the research subjects. The patients were divided into control group and treatment group by random and double blind method, 50 in each group. Both groups were treated by routine basic treatment. The control group was treated with Kidney-invigorating and asthma-relieving Placebo, while the observation group was treated with kidney-invigorating and asthma-relieving granules. All the treatment lasted for 6 weeks. The TCM syndromes scores, Asthma Control Test (ACT) scores, Peak expiratory flow/predicted value (PEF%) and eosinophil in peripheral blood before and after treatment were observed.Results:A total of 91 patients completed the clinical study. There were 45 patients in the control group and 46 in the treatment group. The total effective rate in the treatment group was 93.5% (43/46), while that in the control group was 77.8% (35/45), and the difference was statistically significant ( χ2=4.579, P=0.032). After the treatment, the scores of integral efficacy on syndromes in Chinese medicine, ACT and PEF% in the treatment group were significantly higher than those in the control group ( t values were 2.802, 3.420 and 8.938, respectively, all Ps<0.01). The eosinophil in peripheral blood of patients in the treatment group was significantly lower than that of the control group ( t=3.481, P=0.001). Conclusion:On the basis of conventional treatment of western medicine, kidney-invigorating and asthma-relieving granules can relieve the clinical symptoms of asthma, improve the control level of asthma, enhance the level of PEF, reduce airway inflammation.
ABSTRACT
Objective:To explore the medication regularity of Traditional Chinese Medicine (TCM) for diabetic lower extremity arterial disease (DLEAD) based on data mining.Methods:Search for the clinical literature of treating DLEAD in recent 20 years from China Academic Journal Database (Wanfang Data), China National Knowledge Resources Database (CNKI), China Biomedical Literature Service System (SinoMed) and Chinese Science and Technology Journal Database (Chongqing VIP) dated. The frequency analysis, cluster analysis and association analysis for TCM were carried out respectively through Excel 2019, SPSS 25 and SPSS Modeler 18.Results:There are altogher 175 papers mentioning 201 prescriptions and 186 herbs, among which the top 5 herbs that are used frequently are Astragali Radix, Angelicae Sinensis Radix, Chuanxiong Rhizoma, Achyranthis Bidentatae Radix, Carthami Flos. The taste are mainly sweet and the nature is warm, with liver meridian as the most important maridian. The herbs for activating blood circulation and removing blood stasis are frequently used, followed by Qi tonic and blood tonic herbs. Association Rule Analysis suggested that Astragali Radix, Angelicae Sinensis Radix, Chuanxiong Rhizoma are the herbs that are frequently combined together. Conclusions:The medication for treating DLEAD mainly focuses on promoting blood circulation and removing blood stasis and tonifing Qi and blood. At the same time, the treatment should focus on dispelling wind and dispersing cold, warming yang and unblocking collaterals, resolving phlegm and removing dampness, nourishing yin and clearing heat based on different syndromes. Astragali Radix, Angelicae Sinensis Radix, Chuanxiong Rhizoma were the core herbs. It can be combined with Achyranthis Bidentatae Radix, Pheretma, Paeoniae Radix Rubra, Salviae miltiorrhizae Radix et Rhizoma, Peach Kernel, Carthami Flos to improve the curative effect.
ABSTRACT
Objective:To propose a Chinese diagnostic criterion for rosacea on the basis of clinical feature analysis of rosacea, and to assess its sensitivity and specificity.Methods:A total of 3 350 Chinese patients with newly diagnosed rosacea were collected from Department of Dermatology, Xiangya Hospital, Central South University between December 2017 and July 2018, their phenotypes and clinical features were retrospectively analyzed, and a Chinese modified diagnostic criterion for rosacea was put forward. A national multi-center clinical observational trial, which included 2 269 patients with rosacea and 2 408 patients with other facial skin diseases from 28 centers, was conducted to verify this diagnostic criterion. Then, the sensitivity and specificity of the modified diagnostic criterion were evaluated by comparing with the 2017 standard classification of rosacea developed by the National Rosacea Society Expert Committee (NRSEC) .Results:Fixed centrofacial erythema occurred in 3 350 (100%) patients with rosacea. Flushing occurred before or simultaneously with fixed erythema in 1 850 (99.4%) of the 1 861 patients with erythema on the cheeks; among the 1 489 patients with erythema on the nose or perioral area, only 52 (3.5%) had flushing; all the 342 patients presenting with phymatous changes had fixed erythema before phymatous changes. Based on the above clinical findings, it was proposed that patients with periodically aggravated fixed erythema on the cheeks accompanied with flushing could be diagnosed with rosacea; patients with fixed erythema on the nose and perioral area accompanied with at least one of selective phenotypes (flushing, telangiectasia, papules and pustules, phymatous changes, or ocular manifestations) could be diagnosed with rosacea. The national multi-center clinical observational trial revealed that the sensitivity of the Chinese modified diagnostic criterion for rosacea was 99.6%, which was close to the sensitivity (100%) of the NRSEC standard, and its specificity was 91.9%, higher than the specificity (73.3%) of the NRSEC standard.Conclusion:The Chinese modified diagnostic criterion for rosacea has good sensitivity and specificity, and can facilitate the early diagnosis of phymatous rosacea.
ABSTRACT
Objective:To investigate clinical features of intermittent flushing in patients with rosacea, and to evaluate its impact on the quality of life of patients.Methods:A prospective study was conducted, a total of 728 patients with rosacea were enrolled from Department of Dermatology, Xiangya Hospital from August 2017 to August 2019. Data were collected by using flushing symptom questionnaire (FSQ) , clinician erythema assessment scale (CEA) , patient′s self-assessment (PSA) and visual analogue scale (VAS) . Clinical features and severity of intermittent flushing episodes, degree of bother and impact on life, and correlation of flushing scores with persistent erythema scores were analyzed. Statistical analysis was carried out by using chi-square test and Spearman correlation analysis.Results:Among the 728 patients with rosacea, intermittent flushing most frequently occurred on the cheek (682 cases, 93.7%) and zygomatic region (617 cases, 84.8%) ; the proportion of patients with a flushing duration of 5 minutes to 2 hours was the highest (484 cases, 66.5%) ; 317 (43.6%) had flushing episodes after stimulation, and 233 (32.0%) had multiple flushing episodes every day. Moreover, 503 patients (69.1%) had an overall flushing score above the moderate level; 412 (56.6%) considered that flushing could affect sleep to varying degrees, of which 59 (8.1%) considered that the impact was severe or very severe; 662 (90.9%) considered that flushing had impact on life to different degrees, of which 304 (41.8%) thought that the impact was severe. Both the overall flushing score and life bother score were positively but lowly correlated with the CEA scores ( rs = 0.166, 0.151 respectively, both P < 0.05) , and were positively correlated with the PSA scores ( rs = 0.518, 0.500 respectively, both P < 0.05) . Conclusion:Intermittent flushing occurs at typical sites of patients with rosacea, with long duration of episodes and high frequency, and affects quality of life of patients, so attention needs to be paid by clinicians.
ABSTRACT
Objective To investigate the efficacy and influence factors of uterine artery embolization (UAE)in treatment of intractable postpartum hemorrhage (PPH).Methods 126 patients with intractable PPH were treated by UAE in our hospital.We analyzed the influence factors of failed UAE treatments according to the amount of bleeding,the stability of hemodynamics,with disseminated intravascular coagulation(DIC)or not and active extravasation detected in angiography.Results In 126 intractable PPH patients,13 cases (10.3%) failed to stop bleeding after UAE and the other 113 cases (89.7%)successfully got hemostasis.Logistic regression analysis showed that DIC was a significant factor in failed UAE group (P=0.033,OR 0.107,95%CI 0.014-0.835).Conclusion UAE is an effective method of treating intractable PPH.DIC may be the main cause of the failure of UAE in treatment of intractable PPH.
ABSTRACT
BACKGROUND:It is difficult to perform superselective catheterization of the internal carotid artery in dogs because of the large bending and spiral shape of the interal carotid artery before entering into the skul. At present, the dog models of cerebral infarction established by injecting autologous blood clots and gelatin spongevia the internal carotid artery are far from the perspective of pathological mechanism of human patients with cerebral infarction. Aortography can visualize the structure of cerebral vessels and is likely to provide a new condition for the establishment of dog models of acute cerebral infarction. OBJECTIVE:To explore the feasibility of establishing cerebral infarction models in beagle dogs by superselective catheterizationvia the vertebral basilar artery. METHODS: Five beagle dogs were divided into thrombus group (n=3) and control group (n=2). The beagle dogs in the thrombus group were subjected to digital subtraction angiography of the aortic arch, bilateral common carotid arteries and vertebral arteries in addition to femoral arterial catheterization. The 2.7F micro-catheter was inserted into the convergence zone of the left posterior communicating artery and the internal carotid artery through the vertebrobasilar artery. An autologous blood clot was injected into the convergence zone. The dogs in the control group were injected with appropriate amount of contrast medium. RESULTS AND CONCLUSIONS:Through angiography of the left and right common carotid artery of five dogs, thick external carotid arteries (10/10) and their branches were clearly displayed, however, only five (5/10) internal carotid arteries were dimly present. A spiral vascular loop formed in the internal carotid artery with a smal-sized diameter. Through antiography of the left and right vertebral arteries (10/10) angiography, vertebral basilar artery, the circle of “Wilis”, bilateral posterior cerebral arteries, bilateral middle cerebral arteries and bilateral anterior cerebral arteries were clearly displayed, al these contribute to insertion of microcatheter into the convergence zone of the left posterior communicating artery and the internal carotid artery through the vertebrobasilar artery. High signal intensity of the left temporal lobe was shown on 3-hour and 6-hour diffusion weighted images.The results demonstrate that the beagle dog models of acute cerebral infarction can be successfuly established by injecting autologous blood clots into the left middle cerebral artery through a microcathter insertedvia the vertebrobasilar artery, which provides a new method of precisely occluding the middle cerebral artery of beagle dogs by catheterization.
ABSTRACT
OBJECTIVE@#To investigate the expression profile and the clinical significance of CDK3 in the tissues of nasopharyngeal carcinoma.@*METHOD@#Immunohistochemistry was utilized to detect the expression of CDK3 in 94 cases of NPC and 40 cases of nasopharyngeal inflammation.@*RESULT@#CDK3 was highly expressed in NPC cell lines. Immunohistochemistry showed that CDK3 was mostly expressed in the cytoplasm. The positive expression rate of NPC was 67% and that of nasopharyngeal inflammation was only 12. 5%. The difference between these two groups was highly statistically significant. The CDK3 expression in NPC was related to the TNM clinical staging of NPC (P < 0.01).@*CONCLUSION@#The expression levels of CDK3 were obviously higher in NPC tissues. The CDK3 expression in NPC was related to the TNM clinical staging of NPC. It suggests that CDK3 expression may play an important role in the occurrence and development of nasopharyngeal carcinoma.

Soil archaea and fungi play important roles in the greenhouse soil ecosystem. To develop and apply rich microbial resources in greenhouse ecological environment, and to understand the interaction between microbes and plants, we constructed archaeal 16S rRNA and fungal 18S rRNA gene libraries to analyze the compositions of archaeal and fungal communities. Total greenhouse soil DNA was directly extracted and purified by skiving-thawing-lysozyme-proteinase K-SDS hot treatment and treatment of cetyltriethylammnonium bromide (CTAB). After PCR amplification, retrieving, ligating, transforming, screening of white clones, archaeal 16S rRNA and fungal 18S rRNA gene libraries were constructed. The sequences of archaea and fungi were defined into operational taxonomic units (OTUs) when 97% similarity threshold for OTU assignment was performed by using the software DOTUR. Phylogenetic analysis showed that crenarchaeota and unidentified-archaea were the two major sub-groups and only a few of euryarchaeota existed in the archaeal clone library, total 45 OTUs. All the crenarchaeota belonged to thermoprotei; except for Basidiomycotina, the other four sub-group fungi were discovered in the fungal library, total 24 OTUs. The diversities of archaea were very abundant and a few euryarchaeota (methanebacteria) existed in the archaeal clone library, it might be directly related to the long-term high temperature, high humidity, and high content of organic matter. The limitation of oxygen was the other reason for causing this phenomenon; Ascomycotina (over 80%) was the dominant sub-groups in fungal library. It was because most of the plant fungal diseases belonged to soil-borne diseases which gone through the winter by the ways of scierotium or perithecium and became the sources of primary infection.

Objective To explore the relationship between levels of plasma homocysteine (Hcy) and adrenomedullin (ADM) and sudden sensorineural hearing loss (SSHL) in elderly patients. Methods The 80 patients with SSHL but without any treatment were selected as SSHL group, while 80 age-and sex-matched subjects without SSHL were collected as the control group. The levels of plasma Hcy and ADM were measured by fluorescence method and radioimmunoassay, respectively. And the levels of plasma Hey, ADM, total cholesterol (TC) and triglyceride (TG) were compared between the two groups. Results The levels of plasma Hcy, ADM, TC and TG were significantly higher in SSHL group than in control group [(13. 81±2.88) μmol/L vs. (11. 58±2. 80)/xmol/L, (26. 40±3. 20)ng/L vs. (22. 45±2. 80)ng/L, (5.22±0. 87)mmol/L vs. (4. 52±0. 81)mmol/L, (1.80 ±0. 12)mmol/L vs. (1.52±0. 13)mmol/L;t=5. 03, 8. 22, 7.48, 3. 85, all P<0. 01). When the two groups with hypertension were compared, the levels of plasma Hey, ADM, TC and TG were (15.30±2. 77)μmol/L, (29.40±2. 80) ng/L, (5. 48±0. 98) mmol/L and (1.92±0. 18) mmol/L in SSHL group, which were higher than those in control group[(12. 80±2. 62) μmol/L, (25.20± 2. 60) ng/L, (5.01±1.03) retool/L, (1.62±0. 15) mmol/L3 (t=4.03, 7.01, 3.25, 7. 80, all P< 0. 01). There were no differences in systolic and diastolic blood pressure between the two groups(t= 0. 87, 0. 64;P=0. 38, 0. 55).Conclusions The changes of plasma levels of Hey and ADM in the elderly suggest that they could involve in the pathogenic process of SSHL, which may provide referential value for understanding the state of the disease and judging the prognosis
