ObjectiveTo explore the main mechanism of self-precipitation formed during the decoction of Sinitang（SNT）， and to provide a research basis for exploring the differences in the toxic and effective components of this compound. MethodsThe average precipitation yields of SNT， Glycyrrhizae Radix et Rhizoma（GRR）-Aconiti Lateralis Radix Praeparata（ALRP） decoction（GF）， ALRP-Zingiberis Rhizoma（ZR） decoction（FJ）， GRR-ZR decoction（GJD）， ALRP decoction（FZ）， ZR decoction（GJ） and GRR decoction（GC） were determined. The four main self-precipitation samples of SNT， GF， FZ and GC were physically characterized by particle size， scanning electron microscopy（SEM）， pH， total dissolved solids（TDS）， conductivity， and Fourier transform infrared spectroscopy（FT-IR） analysis. The chemical compositions of SNT decoction and its different phases was identified by ultra-performance liquid chromatography-quadrupole-electrostatic field orbitrap high-resolution mass spectrometry（UPLC-Q-Exactive Orbitrap-MS） for SNT， SNT self-precipitation and SNT supernatant， and the contents of its main toxic and effective components were determined by high performance liquid chromatography（HPLC）. ResultsPrecipitation yield results of the 7 samples of SNT decoction and single decoction showed that SNT had the highest self-precipitation yield. The formation of SNT self-precipitation was mainly related to the reaction between ALRP and GRR components to form complexes， and FT-IR showed that GRR had the greatest influence on the formation of self-precipitation. A total of 110 components were identified in the SNT decoction， including 100 components in the SNT self-precipitation and 106 components in the SNT supernatant. And quantitative results of the main toxic and effective components revealed that the reaction between ALRP and GRR components formed complexes， resulting in the following content hierarchy for free components：SNT decoctionsupernatantself-precipitation， these components included free liquiritin， benzoylmesaconine， benzoylaconitine， benzoylhypacoitine， liquiritigenin， aconitine， hypoaconitine， isoliquiritigenin and ammonium glycyrrhizinate. ConclusionSNT exhibits spontaneous precipitation during compound decoction， with GRR exerting the greatest influence on its formation. This suggests GRR plays a significant role in the detoxification of SNT. The differences in the self-precipitated toxic-effective components of SNT compound decoction primarily manifest as changes in component content， reflecting the characteristics of SNT "deposition in vitro and sustained release in vivo" and the importance of "administered at draught" in the clinical application of SNT.

Objective:To analyze the evaluation of the application effect and deficiency of nurses acting as standardized parents in the graduation examination of standardized residency training of pediatrics and further improve and promote the level of standardized parents.Methods:A questionnaire survey was used to collect the scores of nurse standardized parents by students and examiners who took part in the graduation examination of standardized residency training of pediatrics in 2021. And the self-evaluation scores of standardized parents were collected. Counting data were represented by the number of cases and composition ratio. A Chi-square test was used to compare the rates.Results:A total of 125 questionnaires from students and 37 questionnaires from nurse standardized parents were collected, and the overall satisfaction (very satisfied + satisfied) of standardized parents reached 121 (96.80%). In the three dimensions of simulation ability, compliance with question-and-answer rules, and simulated attitude, students believed that the consistency between standardized parents and actual parents in simulated altitude was lower than that in the simulation ability and compliance with question-and-answer rules ( P=0.007, P=0.001). The overall satisfaction of standardized parents (very satisfied + satisfied) reached 87.38% (388/444). There were 26 (70.27%) nurse standardized parents who had the lowest satisfaction with their own performance ability, followed by 28 (75.68%) cases of imitation ability and 30 (81.08%) cases of adaptability. Conclusions:It is feasible to adopt nurse standardized parents in the assessment of standardized residency training of pediatrics, and both students and examiners have higher satisfaction. The next step is to improve the training of nurses standardized parents in the attitude of simulation and, at the same time, enhance the training of imitation ability and adaptability, so as to further expand the construction of standardized parents.

Endo-periodontal lesions(EPLs)involve both the periodontium and pulp tissue and have complicated etiologies and pathogenic mechanisms,including unique anatomical and microbiological characteristics and multiple contributing factors.This etiological complexity leads to difficulties in determining patient prognosis,posing great challenges in clinical practice.Furthermore,EPL-affected teeth require multidisciplinary therapy,including periodontal therapy,endodontic therapy and others,but there is still much debate about the appropriate timing of periodontal therapy and root canal therapy.By compiling the most recent findings on the etiology,pathogenesis,clinical characteristics,diagnosis,therapy,and prognosis of EPL-affected teeth,this consensus sought to support clinicians in making the best possible treatment decisions based on both biological and clinical evidence.

The development of information technology in the medical industry is accelerating the construction of 3-level rehabilitation networks centering on community-based rehabilitation, which is based on the Internet and in combination with the Internet of things(IOT). A municipal rehabilitation hospital cooperated with the health centers of sub-district communities in the city to build a remote rehabilitation network based on IOT technology, for rehabilitation training of community stroke patients. The two sides worked out a cooperation scheme on project management, designed and built a remote community rehabilitation management model. Under the remote monitoring and equipment data IOT, the medical team of the municipal rehabilitation hospital could formulate the therapeutic plan according to the immediately obtained relevant functional evaluation data, and the medical team of the community health service center was responsible for the implementation of the plan. Fifty-three patients in the experimental group received the training of remote lower limb intelligent feedback system based on IOT together with routine rehabilitation training. After 8 weeks of treatment, the functional evaluation data of the two groups were improved in varying degrees( P< 0.05), but the improvement of the experimental group was significantly better than that of the control group( P < 0.05). Remote rehabilitation under the construction path of remote rehabilitation network based on IOT technology could significantly promote the improvement of post-functional rehabilitation of community stroke patients. This study can provide reference for the construction of three-level remote rehabilitation networks based on IOT and the implementation of home-based remote rehabilitation therapy in the future.

OBJECTIVETo explore the primary site and pathological feature of neuroendocrine neoplasm (NEN), especially the NEN of digestive system.

METHODSClinicopathological data of NEN patients at China-Japan Friendship Hospital from January 2012 to December 2016 were retrospectively analyzed. Tumor primary sites were summarized. Association between tumor site and pathological grading in gastroenteropancreatic neuroendocrine neoplasm(GEP-NEN) was examined.

RESULTSThere were a total of 903 cases of NEN. Sites of primary tumor included the digestive system in 699 cases(77.4%), the thorax(including lung, thymus and mediastinum) in 87 cases(9.6%), other sites in 60 cases (6.6%), unknown in 57 cases(6.3%). Among 699 GEP-NEN cases, the primary sites included the stomachin in 207 cases (29.6%), pancreas in 201 (28.8%), rectumin in 185 (26.5%), duodenum in 43(6.2%), jejunum and ileum in 18(2.6%), appendix in 15 (2.1%), gallbladder in 11(1.6%), esophagus in 10(1.4%), and the colon in 9 cases (1.3%). Pathologically, the tumor grading was neuroendocrine tumor (NET) G1 in 336 cases(48.1%), NET G2 in 203 cases (29.0%), neuroendocrine carcinoma (NEC) G3 in 139 cases (19.9%). All the esophagus NEN(10/10), most gallbladder NEN(9/11) and colon NEN(6/9) were poorly-differentiated NEC (G3), while all appendix NEN(15/15), most stomach NEN(147/207, 71.0%), pancreas NEN (156/201, 77.6%), rectum NEN (169/185, 91.4%), duodenum NEN (31/43, 72.1%), jejunum and ileum NEN(16/18, 88.9%) were well-differentiated NET G1 or G2.

CONCLUSIONSThe most common primary site of NEN is the digestive system. The stomach, pancreas and rectum are most common primary sitesof GEP-NEN. Difference in pathological grading is quite greatin different primary sites of GEP-NEN. Most NENs fromesophagus, colon and gallbladder are poorly-differentiated NEC.

AIM: To investigate the expression and significance of MAPK-interacting kinase-2 ( Mnk2 ) and eukaryotic initiation factor 4E ( eIF4E) in the patients with resected esophageal squamous cell carcinoma ( ESCC ). METHODS:The protein expression of Mnk2 and eIF4E in ESCC tissues (98 cases) and normal esophageal tissues (20 cases) were assessed by immunohistochemistry (IHC), and their correlations with clinicopathological features were statisti-cally analyzed.RESULTS:The over-expression rate of Mnk2 and eIF4E was 68.4%(67/98) and 61.2%(60/98), re-spectively.The expression of Mnk2 had a positive correlation with eIF4E (P<0.05).Clinicopathologic analysis showed that Mnk2 expression was significantly correlated with T classification ( P<0.05 ) and clinical stage ( P<0.05 ) .CON-CLUSION:The over-expression of Mnk2 was significantly related to the tumor invasive depth , TNM stages and expression of eIF4E in ESCC.Expression of Mnk2 and eIF4E may have a cooperative formation mechanism in the development of ESCC.
