ABSTRACT

OBJECTIVE@#To compare the clinical efficacy of combined application of glycine powder air-polishing and mechanical submucosal debridement in non-surgical treatment of peri-implant diseases.@*METHODS@#A randomized controlled clinical study was carried out on patients diagnosed with peri-implant diseases in the Department of Periodontology, Peking University School and Hospital of Stomatology, between May of 2020 and June of 2021.Twenty-eight patients with totally sixty-two implants were enrolled.The patients were randomly divided into the test group and control group. The patients in the test group (13 subjects/32 implants) received mechanical submucosal debridement using titanium curettes combined with application of glycine powder air-polishing, while the control group (15 subjects/30 implants) received mechanical submucosal debridement using titanium only. Clinical parameters, such as plaque index (PLI), pocket probing depth (PPD), bleeding index (BI) and the percentage of suppuration on probing on implants' level (SoP%) were measured at baseline and 8 weeks after non-surgical intervention. Changes and group differences of clinical parameters of the implants before and 8 weeks after non-surgical intervention were compared.@*RESULTS@#Mean PLI, PPD, BI of both the test group and control group significantly reduced 8 weeks after non-surgical intervention (P < 0.05). Compared with the control group, the test group achieved lower BI (2.7±0.8 vs. 2.2±0.7, P < 0.05), more reduction of BI (0.6±0.7 vs. 1.1±0.6, P < 0.01) and more reduction of SoP% (21.9% vs. 10%, P < 0.05) after non-surgical intervention. Both the control and test groups exhibited comparable PLI and PPD reductions (P>0.05). For the implants diagnosed with peri-implant mucositis, the test group revealed more signi-ficant reduction in BI and SoP% than the control group (1.0±0.7 vs. 0.4±0.7, P=0.02; 6.3% vs. 0, P=0.012). There was no significant difference existing in PLI and PD improvement between the control group and test group (P>0.05). For the implants diagnosed with peri-implantitis, there was no significant difference existing in PLI, PPD, BI and SoP% improvement values between the test and control groups (P>0.05). No complications or discomforts were reported during the study.@*CONCLUSION@#Both treatment procedures could relieve the inflammation of peri-implant soft tissue. Non-surgical mechanical submucosal debridement combined application of glycine powder air-polishing is associated with significant reduction of soft tissue bleeding and suppuration on probing especially in the implants diagnosed with peri-implant mucositis.

ABSTRACT

Syndrome is a nonlinear "internal-excess external-deficiency", "dynamic spatial-temporal" and "multi-dimensional" complex system and thus only by using a versatile method can the connotation be expounded. Metabonomics, which is dynamic, holistic, and systematic, is consistent with the overall mode of traditional Chinese medicine(TCM)(holistic view and syndrome differentiation and treatment). Therefore, metabonomics is very important for the research on the differentiation, material basis, and metabolic pathways of syndromes, and efficacy on syndromes. This study reviewed the application of metabonomics in the study of TCM syndromes in recent years, which is expected to objectify the research on TCM syndromes.

ABSTRACT

Chinese medicine processing is a procedure to process medicinal materials under the guidance of traditional Chinese medicine(TCM) theories by using unique methods in China. The medicinal materials can only be used clinically after proper processing. With the development of the modernization of TCM, it is difficult to solve the problems in the inheritance, development, and internationalization of Chinese medicine processing. Metabonomics, a new omics technology developed at the end of the last century, is used to infer the physiological or pathological conditions of the organism with the methods such as NMR and LC-MS via investigating the changes in endogenous small molecule metabolic network after the organism is stimulated by external environment. Metabonomics coincides with the holistic view of TCM because it displays the characteristics of integrity, comprehensiveness, and dynamics, and it has been widely applied in the field of Chinese medicine processing in recent years. This study summarized the application of metabonomics in the processing mechanism and quality control of Chinese medicine processing and prospected the development of this technology in the field of Chinese medicine processing.

ABSTRACT

Berberine is a naturally occurring benzylisoquinoline alkaloid with a wide range of pharmacological activities, such as antibacterial, anticancer, hypolipidemic, antidiabetic and antidiarrheal. Although berberine has a wide range of curative effects, the extremely low bioavailability (< 1%) limits its clinical application. Pure berberine preparations have not yet been approved for any specific disease. The low oral bioavailability of berberine is mainly due to poor solubility caused by self-aggregation under acidic conditions, low permeability, P-glycoprotein (P-gp)-mediated efflux, and liver and intestine metabolism. To improve the oral bioavailability of berberine, researchers have adopted a variety of strategies, including the application of various nano-delivery systems, penetration enhancers and P-gp inhibitors, structural modifications, and development of berberine derivatives. Improving the oral bioavailability of berberine can improve the pharmacological activity of berberine, reduce the dosage, and then reduce the toxic and side effects. This review summarized the various pharmacological activities, metabolism progress and pharmacokinetic characteristics of berberine, the newly discovered berberine target intestinal microbiota and focused on the strategies to improve the oral bioavailability of berberine by improving solubility and permeability, inhibiting P-gp efflux, and structural modification. The research on berberine was prospected, which provided guidance for the in-depth study of berberine.

ABSTRACT

Seborrheic alopecia is a chronic dermatological disease caused by multiple factors. It occurs frequently in young and middle-aged men aged 20-30 years. The main clinical manifestations are greasy hair, itching, excessive dandruff, receding hairline, sparse hair on the top of the head, and progressive hair loss in the frontotemporal area. Seborrheic alopecia is not fatal, but it affects the appearance of patients, seriously harming their self-esteem and bringing great psychological distress to them. The Wnt/β-catenin signaling pathway widely exists in multicellular eukaryotes and is a basic growth regulatory pathway which regulates cell proliferation and differentiation, maintains stem cells activity and organ homeostasis, and affects cell migration. At present, it has been reported in China and abroad that Wnt/β-catenin signaling pathway is closely related to the occurrence and development of seborrheic alopecia and the action mechanism of drugs. Traditional Chinese medicine (TCM) has multi-component, multi-target, and multi-pathway advantages, and it can promote the formation of hair follicle laminae, the proliferation and differentiation of hair follicle stem cells, and the periodic changes in hair follicles by regulating the Wnt/β-catenin signaling pathway, thereby alleviating seborrheic alopecia. This article reviewed the relationship of Wnt/β-catenin signaling pathway and its key target protein factors with seborrheic alopecia to clarify the important role of Wnt/β-catenin signaling pathway in seborrheic alopecia. At the same time, the TCM that targeted the Wnt/β-catenin signaling pathway to relieve seborrheic alopecia were summarized, so as to provide reference for the treatment of seborrheic alopecia and further development of new drugs.

ABSTRACT

ObjectiveTo explore the possible mechanism of total flavonoids of peony flower (TFPF) in protecting rats from gouty nephropathy and provide data support for the pharmaceutical research on the treatment of gouty nephropathy. MethodGouty nephropathy rat model was established by adenine combined with ethambutol. Rats were randomly assigned into blank control group, model group, allopurinol (42 mg·kg-1) group, Tongfengshu tablets (600 mg·kg-1, positive control) group, and TFPF (260, 130, and 65 mg·kg-1) groups. Enzyme-linked immunosorbent assay (ELISA) was employed to measure the levels of tumor necrosis factor-α (TNF-α), monocyte chemoattractant protein-1 (MCP-1), interleukin-1β (IL-1β), and interleukin-18 (IL-18) in rat serum and those of transforming growth factor-β1 (TGF-β1) and IL-1β in renal homogenate. Hematoxylin-eosin(HE) staining was carried out for observation of the morphological changes of renal cells. Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) was conducted for observation of the DNA damage in renal cells. The expression of NOD-like receptor protein 3 (NLRP3), cysteine aspartic acid protease(Caspase)-1 and IL-1β were observed by immunohistochemistry. The expression levels of NLRP3, Caspase-1 and nuclear transcription factor -κB (NF-κB) in renal tissues were detected by Western blot. ResultCompared with blank group, the contents of TNF-α, MCP-1, IL-1β, IL-18, and TGF-β1 in serum of model group were significantly increased (P<0.01), and the expressions of NLRP3, Caspase-1, NF-κB and IL-1β in kidney of model group were significantly increased (P<0.01). The renal tissue cells showed cytoplasmic swelling, cell membrane rupture, and the number of nuclear pyknotic fracture increased. The positive rate of TUNEL staining was significantly increased in model group (P<0.01), and the contents of IL-1β and TGF-β1 in renal tissue homogenate were significantly increased (P<0.01). Compared with model group, the contents of inflammatory factors TNF-α, IL-1β and IL-18 in serum of rats in TFPF high- and medium-dose groups could be decreased to different degrees (P<0.05, P<0.01), while the content of MCP-1 in TFPF high-dose group was significantly decreased (P<0.01). The content of TGF-β1 in renal tissue homogenate in TFPF high- and medium-dose groups was significantly decreased (P<0.05, P<0.01), and the content of IL-1β in renal tissue homogenate in TFPF medium-dose group was significantly decreased (P<0.01). HE staining showed that each dose group of TFPF could improve the status of renal tubular epithelial cells, reduce cytoplasmic swelling and the number of nuclear pyknosis to varying degrees. The positive rate of TUNEL staining was decreased (P<0.01) and DNA damage was decreased. The expression of NLRP3, Caspase-1, IL-1β and NF-κB protein in renal tissue cells was inhibited (P<0.05, P<0.01). ConclusionTFPF protects rats from gouty nephropathy by inhibiting the secretion of inflammatory cytokines. Specifically, it may inhibit the activation of NF-κB and NLRP3/Caspase-1 pathways to reduce the expression, maturation, and release of inflammatory cytokines such as IL-1β and IL-18 and further inhibit pyroptosis, thereby reversing the inflammatory injury of kidney in gouty nephropathy.

ABSTRACT

OBJECTIVE@#To compare the clinical efficacy between Wei's triple nine needling combined with esculin and digitalis glycosides eye drops and esculin and digitalis glycosides eye drops alone for presbyopia complicated with visual fatigue of liver depression and spleen deficiency.@*METHODS@#Forty-six cases (92 eyes) with presbyopia complicated with visual fatigue of liver depression and spleen deficiency were randomly divided into an observation group (23 cases) and a control group (23 cases, 2 cases dropped off). The cases in the observation group were treated with Wei's triple nine needling and esculin and digitalis glycosides eye drops. The acupoints included Shangming (Extra), Chengqi (ST 1), Cuanzhu (BL 2) to Jingming (BL 1), Sizhukong (TE 23) to Taiyang (EX-HN 5), etc; the needling was given once every other day, three times a week, and the eye drops were given one drop each time, three times a day. The cases in the control group were only treated with the eye drops. Both groups were treated for 7 days as one course of treatment, and 2 courses of treatment were given. The visual fatigue core symptoms score, adjustment amplitude, adjustment lag and best average corrected visual acuity were observed in the two groups before treatment, 1 week and 2 weeks into treatment, respectively.@*RESULTS@#Compared before treatment, the visual fatigue core symptoms scores in the two groups were decreased after 1-week and 2-week treatment (P<0.05); in the observation group, the adjustment amplitude was increased after 2-week treatment (P<0.05), while in the control group, the adjustment amplitude was increased after 1-week and 2-week treatment (P<0.05); in the observation group, the adjustment lag was decreased after 1-week and 2-week treatment (P<0.05). After 2-week treatment, the visual fatigue core symptoms score in the observation group was lower than that in the control group, and the adjustment amplitude was higher than that in the control group (P<0.05). There were no significant differences in adjustment lag and best average corrected visual acuity between the two groups after 1-week and 2-week treatment (P>0.05).@*CONCLUSION@#Wei's triple nine needling combined with esculin and digitalis glycosides eye drops could improve the visual fatigue and eye regulation ability in patients with presbyopia complicated with visual fatigue of liver depression and spleen deficiency, and the effect is better than esculin and digitalis glycosides eye drops alone.

ABSTRACT

Cambodia is rich in medicinal plant resources. One hundred and thirty-three medicinal material samples, including the hole herb, root, stem/branch, leaf, flower, fruit, seed, and resin, were collected from the Orussey Herbal Market in Phnom Penh, Cambodia, and then authenticated by ITS and psbA-trnH. A total of 46 samples were identified based on ITS sequences, belonging to 24 families, 40 genera, and 42 species. A total of 100 samples were identified by psbA-trnH sequences to belong to 42 families, 77 genera, and 84 species. A total of 103 samples were identified by two DNA barcodes. According to the morphological characteristics of the medicinal materials, 120 samples classified into 50 species, 86 genera, and 86 families were identified, and the majority of them were from Zingiberaceae, Fabaceae, and Acanthaceae. Such samples have been commonly used in traditional Cambodian medicine, Ayurvedic medicine, Unani medicine, traditional Chinese medicine, and ethnomedicine, but different medical systems focus on different functional aspects of the same medicinal material. The results of this study have demonstrated that DNA barcoding has a significant advantage in identifying herbal products, and this study has provided basic data for understanding the traditional medicinal materials used in Cambodia.

ABSTRACT

Dirigent(DIR) proteins are involved in the biosynthesis of lignin, lignans, and gossypol in plants and respond to biotic and abiotic stresses. Based on the full-length transcriptome of Schisandra chinensis, bioinformatics methods were used to preliminarily identify the DIR gene family and analyze the physico-chemical properties, subcellular localization, conserved motifs, phylogeny, and expression patterns of the proteins. The results showed that a total of 34 DIR genes were screened and the encoded proteins were 156-387 aa. The physico-chemical properties of the proteins were different and the secondary structure was mainly random coil. Half of the DIR proteins were located in chloroplast, while the others in extracellular region, endoplasmic reticulum, cytoplasm, etc. Phylogenetic analysis of DIR proteins from S. chinensis and the other 8 species such as Arabidopsis thaliana, Oryza sativa, and Glycine max demonstrated that all DIR proteins were clustered into 5 subfamilies and that DIR proteins from S. chinensis were in 4 subfamilies. DIR-a subfamily has the unique structure of 8 β-sheets, as verified by multiple sequence alignment. Finally, through the analysis of the transcriptome of S. chinensis fruit at different development stages, the expression pattern of DIR was clarified. Combined with the accumulation of lignans in fruits at different stages, DIR might be related to the synthesis of lignans in S. chinensis. This study lays a theoretical basis for exploring the biological functions of DIR genes and elucidating the biosynthesis pathway of lignans in S. chinensis.

ABSTRACT

In order to solve the problems of erratic drug absorption and low bioavailability after oral administration for poorly-water soluble drugs due to low solubility, a series of novel pharmaceutical dosage forms as solid dispersion, liposome, microemulsion, vesicle, cyclodextrin inclusion complexes and drug nanocrystal have been developed in recent years. Among which drug nanocrystal attracts more attentions for its simpler preparation method, higher drug loading and easier manufacturing technology in the design of dosage forms suitable for different administration routes. In this paper, the nanocrystals of the poorly-water soluble drugs prepared based on bottom-up and top-down technologies were introduced. The characteristics and applications of the nanocrystal-based dosage forms as suspension, tablet and capsule were also introduced and carefully evaluated with the focus on their pharmacokinetics, pharmacodynamics and tissue targeted drug distribution after delivery by oral administration, intravenous injection and pulmonary inhalation. The advantages of drug nanocrystals in their therapeutics effects over the bulk drugs were discussed together with the inherent mechanism. Finally, the problems existing in basic research and scaled-up manufacture of drug nanocrystal as well as the possible ways of solution were listed out so as to make the nanocrystal-based preparations exert their maximum therapeutic effect after clinical application.

ABSTRACT

Xiehuangsan, derived from QIAN Yi's Key to Therapeutics of Children's Diseases, consists of 5 medicines, namely Gypsum Fibrosum,Gardeniae Fructus,Saposhnikoviae Radix,Pogostemonis Herba and Glycyrrhizae Radix et Rhizoma. It is used to treat children with spleen heat and tongue scratching. With the clinical use of later generations of physicians,the scope of diseases and syndromes of this prescription was gradually expanded,including aphthous bad breath,dry lips,yellow eyes,and sweet mouth. Modern doctors used this prescription to treat children with anorexia,constipation,allergic purpura,tic disorder, and other diseases. At present,more and more attention has been paid to the research of classical famous prescriptions. At the same time,the application of classical famous prescriptions of traditional Chinese medicine(TCM) must be researched and verified in ancient literature. Therefore,it has become important contents in the study of classic prescriptions that researching the source of prescriptions from the ancient books,combing and analyzing literature,and studying the evolution rules of indications,preparations,methods of administration and taboos.The author searched a variety of ancient Chinese medicine databases and collected the relevant documents related to Xiehuangsan in ancient medical books. A total of 242 pieces of relevant ancient document data were obtained,involving 131 types of ancient Chinese medicine books. Through combing the relevant records of historical documents,this paper analyzes and researches the historical evolution of Xiehuangsan,the source and composition of the prescriptions,the indications,the dosage,the textual research of Chinese herbal medicine and the determination of the basis,and the method of prescription preparation and administration,etc. The historical changes of Xiehuangsan and its internal relations are expected to provide literature references and theoretical basis for the modern development and research of Xiehuangsan.

ABSTRACT

@#Objective    To summarize our experience of surgical resection of multiple ground-glass opacity (GGO) in recent years. Methods    Clinical data of patients who underwent one-stage resections of multiple GGO from November 2015 to May 2019 in our hospital were collected, including 13 males and 52 females at an average age of 56.0±9.4 years. The clinical effects and pathological types of GGO were evaluated. Results    Time interval from first discovery to surgery was 8-1 447 (236.5±362.4) days. There were 48 patients with unilateral surgery and 17 patients with bilateral surgery during the same period. Except for 2 patients who underwent open thoracotomy due to total thoracic adhesions, other patients underwent video-assisted thoracoscopic surgery (VATS). The mean postoperative hospital stay was 12.2±4.3 days. No severe perioperative complication or death occurred. A total of 156 GGO lesions were resected, 80 lesions were pure GGO, including 58 (72.5%) malignant lesions and 22 (27.5%) benign lesions, with an average diameter of 7.7±3.3 mm and 5.5±2.6 mm, respectively. Another 76 lesions were mixed GGO, including 69 (90.8%) malignant lesions and 7 (9.2%) benign lesions, with an average diameter of 13.6±6.6 mm and 7.7±3.5 mm, respectively. Conclusion    Patients with multiple GGO should be treated with anti-inflammatory therapy firstly. When conservative treatment is ineffective and no benign outcomes are observed, surgical treatment should be considered. And when lung function is sufficient for patients to underwent surgeries, the simultaneous unilateral or bilateral thoracoscopic resection is suggested, and the sublobar resection or lobectomy methods can be adopted flexibly according to the clinical features of the lesion and the rapid pathological results, which will not increase the risk of postoperative complications. Otherwise, surgical resection should be given priority for pure GGO lesions with a diameter > 7.7 mm and mixed GGO lesions.

ABSTRACT

Objective: Schisandra sphenanthera and S. chinensis are the two important medicinal plants that have long been used under the names of “Nan-Wuweizi” and “Wuweizi”, respectively. The misuse of “Nan-Wuweizi” and “Wuweizi” in herbal medical products calls for an accurate method to distinguish these herbs. Chloroplast (cp) genomes have been widely used in species delimitation and phylogeny due to their uniparental inheritance and lower substitution rates than that of the nuclear genomes. To develop more efficient DNA markers for distinguishing S. sphenanthera, S. chinensis, and the related species, we sequenced the cp genome of S. sphenanthera and compared it to that of S. chinensis. Methods: The cp genome of S. sphenanthera was sequenced at the Illumina HiSeq platform, and the reference-guided mapping of contigs was obtained with a de novo assembly procedure. Then, comparative analyses of the cp genomes of S. sphenanthera and S. chinensis were carried out. Results: The cp genome of S. sphenanthera was 146 853 bp in length and consisted of a large single copy (LSC) region of 95 627 bp, a small single copy (SSC) region of 18 292 bp, and a pair of inverted repeats (IR) of 16 467 bp. GC content was 39.6%. A total of 126 functional genes were predicted, of which 113 genes were unique, including 79 protein-coding genes, 30 transfer RNA (tRNA) genes, and four ribosomal RNA (rRNA) genes. Five tRNA, four protein-coding genes, and all rRNA were duplicated in the IR regions. There were 18 intron-containing genes, including six tRNA genes and 12 protein-coding genes. In addition, 45 SSRs were detected. The whole cp genome of S. sphenanthera was 123 bp longer than that of S. chinensis. A total of 474 SNPs and 97 InDels were identified. Five genetic regions with high levels of variation (Pi > 0.015), trnS-trnG, ccsA-ndhD, psbI-trnS, trnT-psbD and ndhF-rpl32 were revealed. Conclusion: We reported the cp genome of S. sphenanthera and revealed the SNPs and InDels between the cp genomes of S. sphenanthera and S. chinensis. This study shed light on the species identification and further phylogenetic study within the genus of Schisandra.

ABSTRACT

Objective:To investigate the effect of vagus nerve stimulation (VNS) on the autophagy in penumbra of rats after middle cerebral artery occlusion (MCAO). Methods:A total of 56 Sprague-Dawley rats were divided into control group (n = 14), sham group (n = 14), model group (n = 14) and VNS group (n = 14). The model group and VNS group accepted MCAO for one hour, then reperfusion, and VNS group accepted VNS in the left as MCAO for 0.5 hour. Their infarct volume was detected with TTC staining, neurological impairment was assessed with Longa's score, and the expression of Beclin-1, microtubule-associated protein 1 light chain 3 (LC3)-II/I, phosphorylated adenosine monophosphate activated protein kinase (P-AMPK) and silent mating type information regulation 2 homolog 1 (Sirt1) were detected with Western blotting 24 hours after reperfusion. Results:Compared with the sham group, the infarct volume and Longa's score increased in the model group, while the expression of Beclin-1, LC3-II/I, P-AMPK and Sirt1 decreased significantly (P < 0.001). Compared with the model group, the infarct volume and Longa's score reduced (P < 0.05) in VNS group, while the expression of Beclin-1, LC3-II/I, P-AMPK and Sirt1 increased significantly (P < 0.001). Conclusion:VNS may alleviate cerebral ischemic injury in rats through AMPK-Sirt1 pathway.

ABSTRACT

Pyrrosia petiolosa, Pyrrosia lingua and Pyrrosia sheareri are recorded as original plants of Pyrrosiae Folium (PF) and commonly used as Chinese herbal medicines. Due to the similar morphological features of PF and its adulterants, common DNA barcodes cannot accurately distinguish PF species. Knowledge of the chloroplast (cp) genome is widely used in species identification, molecular marker and phylogenetic analyses. Herein, we determined the complete cp genomes of three original species of PF via high-throughput sequencing technologies. The three cp genomes exhibited a typical quadripartite structure with sizes ranging from 158 165 to 163 026 bp. The cp genomes of P. petiolosa and P. lingua encoded 130 genes, whilst that of P. sheareri encoded 131 genes. The complete cp genomes were compared, and five highly divergent regions of petA-psbJ, matK-rps16, ndhC-trnM, psbM-petN and psaC-ndhE were screened as potential DNA barcodes for identification of Pyrrosia genus species. The phylogenetic tree we obtained indicated that P. petiolosa and P. lingua are clustered in a single clade and, thus, share a close relationship. This study provides invaluable information for further studies on the species identification, taxonomy and phylogeny of Pyrrosia genus species.

ABSTRACT

BACKGROUND@#Homozygous or compound heterozygous mutations in high temperature requirement serine peptidase A1 (HTRA1) gene are responsible for cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy (CARASIL). Recently, increasing evidence has shown that heterozygous HTRA1 mutations are also associated with cerebral small vessel disease (CSVD) with an autosomal dominant pattern of inheritance. This study was aimed to analyze the genetic and clinical characteristics of HTRA1-related autosomal dominant CSVD.@*METHODS@#We presented three new Chinese cases of familial CSVD with heterozygous HTRA1 mutations and reviewed all clinical case reports and articles on HTRA1-related autosomal dominant CSVD included in PUBMED by the end of March 1, 2020. CARASIL probands with genetic diagnosis reported to date were also reviewed. The genetic and clinical characteristics of HTRA1-related autosomal dominant CSVD were summarized and analyzed by comparing with CARASIL.@*RESULTS@#Forty-four HTRA1-related autosomal dominant CSVD probands and 22 CARASIL probands were included. Compared with typical CARASIL, HTRA1-related autosomal dominant probands has a higher proportion of vascular risk factors (P < 0.001), a later onset age (P < 0.001), and a relatively slower clinical progression. Alopecia and spondylosis can be observed, but less than those in the typical CARASIL. Thirty-five heterozygous mutations in HTRA1 were reported, most of which were missense mutations. Amino acids located close to amino acids 250-300 were most frequently affected, followed by these located near 150∼200. While amino acids 250∼300 were also the most frequently affected region in CARASIL patients, fewer mutations precede the 200th amino acids were detected, especially in the Kazal-type serine protease domain.@*CONCLUSIONS@#HTRA1-related autosomal dominant CSVD is present as a mild phenotype of CARASIL. The trend of regional concentration of mutation sites may be related to the concentration of key sites in these regions which are responsible for pathogenesis of HTRA1-related autosomal dominant CSVD.

ABSTRACT

@#Objective    By summarizing the clinical characteristics of perioperative patients with cross infection of novel coronavirus in thoracic surgery ward, to guide the prevention and treatment of nosocomial infection during the anti-epidemic period. Methods    The clinical data of 451 patients with chest diseases in the Department of Thoracic Surgery of Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology from January 1st to 24th, 2020 were analyzed and followed up. There were 245 surgical patients and 206 non-surgical patients. Results    In the department, 7 patients (7/451, 1.55%) were infected with the novel coronavirus and all of them were surgical patients, whose preoperative imaging data did not reveal the imaging changes of novel coronavirus. There were 5 males and 2 females, aged 56 to 68 years. The patients with old age, smoking, surgery, coronary heart disease, chronic liver disease and tumor history were more susceptible to infection. From the spatial distribution of patient beds, it was found that the distance among infected patients was greater than 1 m, and no cross infection was found in the other patients of the same ward. During follow-up, two family members of noninfected patients were found to be infected one week after discharge. However, there was no overlap of spatiotemporal distribution between the family members and the infected patients during the hospitalization period. Conclusion    The novel coronavirus pneumonia rate in the department of  thoracic surgery is low, which may be opportunistic infection. At the same time, a good control and prevention of epidemic disease can reduce the occurrence of cross infection in the department of thoracic surgery.

ABSTRACT

The blood brain barrier can selectively block the uptake of xenobiotics from peripheral blood into the brain. Although this is important for maintaining the stability of the brain environment and normal function of the central nervous system, it presents a challenge for delivery of therapeutic drugs to the brain. Passive brain-targeting drug carrier is able to increase the drug concentration in the brain by enhancing the affinity to blood-brain barrier and/or inhibiting the efflux absorbed drug via P-glycoprotein. The active brain-targeting drug carrier can be obtained by linking specific ligands or antibodies onto passive target carriers to achieve precise delivery of drugs to the brain. Dual targeting drug carriers obtained by combining tumor cell targeting with brain targeting have shown their advantages for treatment of brain tumors. The targeted drug delivery to brain will provide a unique manner for the treatment of brain diseases such as Alzheimer's, Parkinson's, brain tumors, and stroke. Among the drug delivery systems of passive brain-targeting, active brain-targeting and dual brain-targeting, we evaluated the strategies to improve brain drug delivery efficiency, such as by reducing carrier size, opening tight junctions between cells at the blood-brain barrier, incorporating hydrophilic groups on the surface of the carrier, and alternative intranasal drug administration.

ABSTRACT

" 's triple nine needling therapy" is the crucial acupuncture prescription in treatment of eye diseases in 's academic school of ophthalmology. " 's triple nine needling therapy" includes the three points near to the eyes, the three groups of points for penetrating acupuncture around the eyes and the acupoint selection based on the general differentiation of syndrome. In this paper, the acupoint selection and the thinking of acupoint combination were introduced in the treatment of optic nerve disease on the base of the theory of " 's triple nine needling" prescription. The specific needling manipulations at different regions involved in the triple needling procedure were explained in detail. It is proposed that the acupoints are combined and the correct needling manipulations selected rationally in compliance with the illness condition and the syndrome characteristics to ensure maximally the clinical effects of " 's triple nine needling therapy".
