OBJECTIVETo retrospectively explore the effectiveness of surgical intervention model for repairing the tuberculosis wound with sinus tract.
METHODSForty-three patients with tuberculosis wound with sinus tract who met the inclusion criteria were admitted to the 309th Hospital of PLA from January 2010 to October 2015. These patients were divided into test group (n=38) and control group (n=5) according to the different treatment and patient's consent. Patients in test group were treated as follows. Firstly, antituberculosis drugs were taken orally for at least 3 weeks, and the wounds were accurately assessed using magnetic resonance imaging combined with 3-dimensional reconstruction software. Then sinus tract and its surrounding devitalized tissue were completely excised, and vacuum sealing drainage (VSD) treatment with negative pressure value of -26.6 kPa was performed for 1 to 2 weeks (dressing change was performed per 7 days). Lastly, the wounds were covered through direct suture or grafting skin or flap. Patients in control group were firstly given antituberculosis drugs orally for at least 3 weeks, and then they were treated with routine dressing change in outpatient service every 3 days. After the former therapy, patients in both groups were given antituberculosis drugs by oral administration for at least 6 months and were followed up for 6 to 36 months. Detection of Bacillus tuberculosis, Acid-fast bacilli, and tuberculosis granuloma, wound healing time, and relapse of tuberculosis wound in patients of both groups were recorded. The rates of single sinus tract, two sinus tracts, and more than or equal to 3 sinus tracts of patients in test group were recorded. Data were processed with Fisher's exact test and Wilcoxon rank-sum test.
RESULTSBacillus tuberculosis was respectively detected in wounds of 5 patients in test group and 2 patients in control group. Acid-fast bacilli were positively expressed in wounds of 8 patients in test group and 3 patients in control group. A typical tuberculosis granuloma phenomenon was observed in the wounds of 27 patients in test group and 4 patients in control group. These differences in above-mentioned 3 indexes between two groups were not statistically significant (with P values respectively 0.238 4, 0.154 4, 1.000 0). The median of wound healing time of patients in test group was 19.6 d, which was significantly shorter than that in control group (94.4 d, χ(2)=12.986 0, P=0.000 3). There were 2 and 1 patients with recurrent tuberculosis wound in test group and control group respectively, without statistically significant difference (P=0.363 0). Among patients in test group, the rate of single sinus tract was 23.7%(9/38), the rate of two sinus tracts was 28.9%(11/38), and the rate of more than or equal to 3 sinus tracts was 47.4% (18/38).
CONCLUSIONSRepairing the tuberculosis wound with sinus tract in surgical intervention model of antituberculosis therapy+ accurate wound assessment+ debridement+ VSD treatment+ surgical repair is beneficial to making the optimal operation plan under the premise of knowing location of sinus tract, which can reduce surgical risk.

ObjectiveBased on the integrated strategy of "empirical prescriptions in ancient books-medical cases by prestigious doctors-computational analysis", this study aims to explore and analyze the prescriptions and medical cases for treating tremors in traditional Chinese medicine (TCM), predict their efficacy, and obtain the core prescriptions for treating tremors in TCM, providing references for clinical application and new drug development. MethodThe Chinese Medicine Prescription Database and the China National Knowledge Infrastructure (CNKI) were searched for relevant prescriptions and medical cases for treating tremors in TCM to establish a database of prescriptions for tremors. The Traditional Chinese Medicine Inheritance Computer System (V3.0) was used to analyze and explore the medication rules including drug frequency, properties, flavor, meridian tropism, and pharmacological effects, as well as core drugs and formula associations. A multi-target drug efficacy prediction platform based on network robustness was used to evaluate the predicted efficacy of the core prescriptions obtained. Based on the integration of ancient prescriptions, prestigious doctors' medical cases, and network analysis results, the priority level of the developed prescriptions was determined through comprehensive evaluation. ResultA total of 81 ancient prescriptions were screened, involving 246 drugs, and 171 prescriptions were screened from prestigious doctors' medical cases, involving 278 drugs. The frequently used TCM drugs were mostly warm in nature and sweet in flavor, mainly acting on the liver, spleen, and kidney meridians. In terms of efficacy, they were mainly effective in tonifying deficiency, soothing liver and extinguishing wind, activating blood and resolving blood stasis, clearing heat, and resolving exterior. Through association rules and K-means clustering, the core prescriptions were composed of high-frequency drugs such as Glycyrrhizae Radix et Rhizoma, Ginseng Radix et Rhizoma, Astragali Radix, Atractylodis Macrocephalae Rhizoma, Angelicae Sinensis Radix, Poria, Gastrodiae Rhizoma, and Uncariae Ramulus Cum Uncis. Drug combinations mainly focused on tonifying Qi and nourishing blood, with the additional functions of calming wind and dredging collaterals. Clustering analysis of core prescriptions from ancient prescriptions and prestigious doctors' medical cases, as well as multi-target drug efficacy prediction, showed that Combination 1 had the highest disturbance score on the disease network. Furthermore, comparative analysis revealed consistent results with both the analysis of ancient prescriptions and prestigious doctors' medical cases, indicating its optimal development potential based on theoretical inheritance and empirical practice. In comparison, Combinations 3, 2, and 4 were less utilized in contemporary clinical practice, with lower rankings in network disturbance scores, suggesting that their development value still warranted further exploration. ConclusionTCM clinical treatment of tremors emphasizes the regulation of the liver, spleen, and kidney. In line of syndrome differentiation, drugs potent in soothing liver, extinguishing wind, activating blood, and resolving blood stasis are added based on deficiency-tonifying drugs. The core prescriptions based on Glycyrrhizae Radix et Rhizoma, Angelicae Sinensis Radix, Paeoniae Radix Alba, Astragali Radix, Poria, and Atractylodis Macrocephalae Rhizoma (combination 1) have the highest potential development value. The integrated strategy "empirical prescriptions in ancient books-medical cases by prestigious doctors-computational analysis" can be used for the screening of candidate prescriptions for new TCM drugs.

ObjectiveAfter the brain and heart injuries were simulated by myocardial injury caused by acute cerebral ischemia, this study explored the mechanism of Naoxintong capsules in treating brain and heart injuries under cerebral ischemia state with Toll-like receptor (TLR) 2/TLR4 as the breakthrough point. MethodC57BL/6 male mice were randomly assigned into the sham operation, model, Naoxintong, and Ginaton groups. The middle cerebral artery occlusion (MCAO) method was used to establish a mouse model of cerebral ischemia. The neuroethological score, cerebral infarction area, cell apoptosis, ionized calcium-binding adaptor molecule 1 (IBA-1)-positive microglia proportion, and serum levels of N-terminal pro-brain natriuretic peptide (NT-proBNP), creatine kinase-MB (CK-MB), and lactic dehydrogenase (LDH) were determined to evaluate the pharmacodynamic effects of Naoxintong capsules on heart and brain injuries after cerebral ischemia in mice. Western blotting was employed to determine the expression of TLR2/TLR4 protein in the brain and heart of mice. ResultCompared with the sham operation group, the model group showed increased cerebral infarction area, neuroethological score, apoptosis rate, IBA-1-positive microglia proportion, and serum levels of NT-proBNP, CK-MB, and LDH (P<0.01). Naoxintong capsules reduced the cerebral infarction area, neuroethological score, apoptosis rate, IBA-1-positive microglia proportion (P<0.01), and serum NT-proBNP and CK-MB levels (P<0.05) in mice compared with the model group. Western blotting results showed that Naoxintong Capsules down-regulated the expression levels of TLR2 (P<0.05) in the brain and TLR2 (P<0.01) and TLR4 (P<0.05) in the heart. ConclusionCerebral ischemia can cause myocardial damage, reflecting the pathological process of cardiac injury after cerebral ischemia. Naoxintong capsules can mitigate brain and heart injuries after cerebral ischemia and achieve the simultaneous treatment of the brain and the heart, in which TLR2/TLR4 plays a role.

ObjectiveTo explore the mechanism of Naoxintong capsules' intervention in cerebral ischemia-reperfusion by building a mouse cerebral ischemia-reperfusion model based on short-chain fatty acids. MethodC57BL/6J male mice were randomly divided into the sham group, model group, Naoxintong group (158.9 mg∙kg-1), and Ginaton group (12.1 mg∙kg-1) according to the random number table method. The model of cerebral ischemia-reperfusion (MCAO/R) was prepared via the filament occlusion method. The effect of Naoxintong capsules on brain injury in MCAO/R mice was evaluated by the neuroethological score, cerebral infarction area determination, Nissl staining, and immunofluorescence staining. Hematoxylin-eosin (HE) staining and Western blot were employed to evaluate the effect of Naoxintong capsules on the intestinal barrier in MCAO/R mice. The content of short-chain fatty acids in mouse feces was detected by LC-MS/MS. ResultCompared to the sham group, the model group exhibited significant increases in the cerebral infarction area, neuroethological score, and cell apoptosis rate (P<0.01), with a notable decrease in the number of Nissl bodies (P<0.01). The protein expression levels of Claudin-1 and Occludin were significantly reduced (P<0.05). Compared with the model group, the intervention of Naoxintong capsules significantly decreased the cerebral infarction area (P<0.05) and improved the neuroethological score (P<0.01) and cell apoptosis rate (P<0.01), with the number of Nissl bodies (P<0.01) and expression levels of Claudin-1 and Occludin proteins (P<0.01) increased. LC-MS/MS results showed that compared to the sham group, the model group featured a significantly reduced content of acetic acid, propionic acid, and butyric acid in feces (P<0.01), while valeric acid, isovaleric acid, and isobutyric acid levels were increased (P<0.01). The intervention of Naoxintong capsules notably lowered the content of valeric acid, isovaleric acid, and isobutyric acid (P<0.01). ConclusionNaoxintong capsules can improve brain and intestinal barrier damage and play a protective role in cerebral ischemia-reperfusion by regulating the content of short-chain fatty acids.

Stem cell research has become a frontier in the field of life sciences, and provides an ideal model for exploring developmental biology problems such as embryogenesis, histiocytosis, and gene expression regulation, as well as opens up new doors for clinical tissue defective and inheritance diseases. Among them, menstrual blood-derived stem cells (MenSCs) are characterized by wide source, multi-directional differentiation potential, low immune rejection characteristics. Thus, MenSCs can achieve individual treatment and have the most advantage of the clinical application. The central nervous system, including brain and spinal cord, is susceptible to injury. And lethality and morbidity of them tops the list of all types of trauma. Compared to peripheral nervous system, recovery of central nervous system after damage remains extremely hard. However, the treatment of stem cells, especially MenSCs, is expected to solve this problem. Therefore, biological characteristics of MenSCs and their treatment in the respect of central nervous system diseases have been reviewed at home and abroad in recent years, so as to provide reference for the treatment of central nervous system diseases.
