BACKGROUND:Medical hydrogels are new functional polymer materials with three-dimensional structural networks and excellent biocompatibility,which have been widely studied in the field of tissue engineering and drug carriers,but the research on the combination of medical hydrogels and Chinese medicine for the treatment of diseases based on tissue engineering is still in the early exploration stage.Therefore,through the analysis of the mechanism of the role of medical hydrogels,the integration of medical hydrogels and Chinese medicine in the research of the joint application of the article,can better provide ideas for scientific researchers,and the joint application of Chinese medicine and medical hydrogels is of great significance. OBJECTIVE:To explore the strategy and significance of Chinese medicine combined with medical hydrogel for disease treatment based on tissue engineering research. METHODS:PubMed and CNKI were used to retrieve articles about the application of Chinese medicine combined with medical hydrogel in tissue engineering from January 2010 to November 2022,with the Chinese and English search terms"hydrogel,traditional Chinese medicine,drug carrier,tissue engineering".After the initial screening of all articles according to the inclusion and exclusion criteria,the 61 articles with high relevance were retained for review. RESULTS AND CONCLUSION:(1)Although the application of Chinese medicine combined with medical hydrogel is involved in intra-articular,intra-tissue organ,soft tissue wounds,tissue engineering,etc.,except for the clinical application of Chinese medicine combined with hydrogel dressing for soft tissue injury,other aspects are still in the experimental stage.(2)The development of Chinese medicine combined with medical hydrogel has great potential and development prospects,but there is a certain difficulty in the manufacture of the gel with high-performance requirements,and it is difficult to master the physical and chemical properties precisely.(3)At present,the comprehensive view of injectable hydrogel with the characteristics of easy to use,its joint use of Chinese medicine can be extended to a wider range,can be used for joint,organ,tissue engineering-related disease treatment.Smart hydrogel has high sensitivity and reversible transformation can also meet the use of the special environment.During the combined use of Chinese medicine,it also needs to understand the mechanism of action of Chinese medicine components.(4)The strategy of combining Chinese medicine with medical hydrogels for disease treatment should start with matching the therapeutic effects of Chinese medicine on organs,tissues and cells combined with appropriate types of medical hydrogels to make up for the shortcomings of traditional Chinese medicine delivery methods and frequent drug delivery.In tissue engineering,hydrogels can be loaded with stem cells after Chinese medicine intervention,or with both Chinese medicine and stem cells for disease treatment.(5)In future research of combined Chinese medicine and medical hydrogel application,we also need to consider:we should ensure that the biological properties of medical hydrogel can be quantified,and grasp the characteristics of hydrogel with different manufacturing processes of different materials to produce the required medical hydrogel that meets the application conditions.In Chinese medicine,we need to comprehensively understand and analyze the therapeutic effects and application mechanisms of known Chinese medicine monomer and Chinese medicine compound extracts,so as to achieve a more perfect combination between Chinese medicine and medical hydrogel under a more clear mechanism.With the continuous improvement of medical science and technology innovation,the medical hydrogel can be innovatively combined with other traditional treatment methods of Chinese medicine,such as acupuncture,massage,cupping and so on,to be used from multiple angles.

Objective:A subunit vaccine against SARS-CoV-2 BA.2 variant was prepared by prokaryotic expression system and its immunogenicity was evaluated.Methods:The recombinant plasmid of BA.2 variant RBD and the tandem of RBD and TT-P2 epitopes was constructed by molecular cloning technology, and recombinant proteins So and Sot were obtained by protein purification technology. Mice were immunized by intramuscular injection after mixing protein So/Sot as immunogens with Al(OH) 3 adjuvant to evaluate the effect of cellular and humoral immunity.

Objective To study the clinical and genetic characteristics of congenital hyperinsulinism (CHI).Method From November 2016 to November 2018,a cohort of 21 patients with CHI were retrospectively reviewed in our hospital.The second generation sequencing was performed on Ion torrent platform to identify the genetic etiology of this disease.Result The average birth weight was 3 748 g.Overall,11 of the 21 patients (52.4％) were large for gestational age (＞ Pg0),and 90.5％ (19/21) onset within 3 days after birth.Seizures occurred in 7 cases (33.3％).Diazine was effective in alleviation in 6 patients,octreotide was effective in 8 patients,and diazine and octreotide were ineffective in 7 patients.11 patients underwent 18-fluoro-l-dopa PET-CT scan,indicating focal islet cell proliferation in 8 patients and diffuse islet cell proliferation in 3 patients.8 focal cases accepted the partial pancreatectomy (7 cases who failed to respond to drug therapy,1 case who received octreotide had significant liver damage),and all of these 8 cases were confirmed with focal islet cell proliferation by postoperative pathology.7 cases had normal glucose level after surgery,while 1 case developed insulin-dependent diabetes.Patients of 3 cases with diffuse islet cell proliferation had no consent for surgery.Gene mutations were identified in 61.9％ (13/21) of patients (12 cases of ABCC8 gene and 1 case of KCNJ11 gene).15 sequence changes were identified (14 in ABCC8 and 1 in KCNJ11).3 new ABCC8 gene mutations (exon13:c.1822C ＞ T,p.Q608X;exon22:c.2691delC,p.W898Gfs*5;exon33:c.4039C ＞T,p.Q1347X),and 1 new KCNJJ11 gene mutation (exon1:c.629T ＞ A,p.H315Y) were firstly reported.Conclusion Partial pancreatectomy is an effective treatment for those CHI not responsive to drug,however,with an attendant risk of developing diabetes.Mutations of ABCC8 gene and KCNJJ11 gene are the main pathogenic genes of CHI.Patients with different gene mutations may have different responses to drug treatment.Therefore,it is necessary to improve gene testing in clinical practice to guide treatment and prognosis.3 new ABCC8 gene mutations and 1 new KCNJJ11 gene mutation were first reported,which expand the spectra of gene mutation.

Objective:To investigate the clinical significance of six serological methods for diagnosis of brucellosis.Methods:Totally 160 cases of brucellosis patients were selected as the case group and 235 cases of health medical examiners were selected as the control group from January to June 2018 in Heilongjiang Agricultural Reclamation Bureau General Hospital. Six methods were used for detection of brucellosis, including Rose Bengal plate agglutination test (RBPT), fluorescence polarization assay (FPA), indirect enzyme linked immunosorbent assay (iELISA), cysteine agglutination test, standard tube agglutination test (SAT), and anti-globulin test (Coomb's). The consistency of the 4 preliminary screening methods (RBPT vs FPA, iELISA, cysteine agglutination test), and 2 diagnosis methods (SAT vs Coomb's) was compared, and the sensitivity, specificity, rates of missed diagnosis and misdiagnosis were analyzed. Results:In the preliminary screening methods, the consistency of RBPT with FPA and iELISA was relatively consistent (Kappa = 0.872, 0.784), and the consistency with cysteine agglutination test was generally consistent (Kappa = 0.543). In the diagnosis methods, the consistency between SAT and Coomb's was relatively consistent (Kappa = 0.861). The sensitivity of FPA, iELISA, cysteine agglutination test and Coomb's was 91.03%, 75.00%, 56.41% and 80.14%, respectively. The specificity was 95.81%, 100.00%, 98.74% and 100.00%, respectively. The rates of missed diagnosis were 8.97%, 25.00%, 43.59% and 19.86%, respectively. The rates of misdiagnosis were 4.19%, 0, 1.26%, and 0, respectively.Conclusions:FPA and iELISA have high sensitivity and specificity, and are suitable for clinical promotion. The combined detection of multiple serological methods will reduce the probability of misdiagnosis and missed diagnosis of brucellosis, thereby improving the diagnostic level of brucellosis.
