Objective To investigate the effect of Shenfuhuang injection (SFH Injection) on function of organs and mortality of septic rats, using a sepsis mode by cecal ligation puncture(CLP). Methods 140 male Wistar rats were randomly divided into four groups: normal control group, sham operation group, CLP group (being further divided into 2, 8, 24, 48 h subgroups), SFH injection treatment group (being further divided into 2, 8, 24, 48 h subgroups, drug were inraveous injected just after operation and per 12 h). The mortality of animals and altering organ’s function were observed within 7 days. Results Compared to CLP model, mortality of Septic rats in SFH injection group was significant lower, and the treatment prolonged survival duration. SFH Injection group owned lower numerical values of ALT, AST, BUN and Cr in serum. Conclusion SFH Injection can obviously decline the mortality of septic rats and play an important role in protecting organ function.

Objective To evaluate the effect of Shenfuhuang injection (SFH) on tissue and plasma TNF-? level and multiple organ dysfunction in septic rats. Method Wistar rats were subjected to sepsis by ceral ligation and puncture, then they were randomly divided into four groups, normal control, sham operation grop, septic group, SFH group. Animals were sacrificed at 2, 8, 24, 48 h. TNF-? level of lung, liver and plasma were measured. DAO activity was determined. Result TNF-? level of liver, lung and plasma were markedly increased at 2～8 h post-CLP compared with sham operation group. In SFH group, TNF-? level decreased in different degrees. DAO activity was much lower in SFH group than in CLP group at 2, 8 h. Conclusion Early applying of SFH could markedly inhibit TNF-? level of vital organs and injury of intestine, thereby preventing the development of excessive inflammation response and subsequent multiple organ dysfunction syndrome associated with CLP-induced sepsis.

OBJECTIVEThis study aimed to evaluate the vascular endothelial growth factor (VEGF) expression and permeability of vascular endothelial cell under microvibration.

METHODSHuman umbilical vein endothelial cell (HUVEC) were cultured, randomly vibrated under low frequency of 0.2, 0.5, 2, 5 Hz, 30 min per day. The VEGF mRNA level was detected by Tagman probe real-time fluorescence quantitative polymerase chain reaction (PCR), and the VEGF protein expression level was detected by Western blot.

Objective:To explore the relationship between hematocrit, early fluid therapy, and clinical outcomes in patients with septic shock, and to provide evidence for fluid resuscitation therapy and prognosis assessment in these patients.Methods:The clinical information of patients with septic shock who were diagnosed and treated in the Emergency Intensive Care Unit (EICU) of the First Affiliated Hospital of Wenzhou Medical University from January 1, 2018 to December 31, 2020 were collected. Taking the survival or death of patients 28 days after admission as the end point of clinical research, the patients were divided into the survival and death groups. After analyzing the basic data of the two groups, the univariate and multivariate COX regression analyses were used to analyze the evaluation value of Δ Hematocrit (HCT) d2-d1 and ΔHCT d3-d1 on the prognosis of patients with septic shock. At the same time, the Kaplan-Meier survival curve was used to analyze the overall survival rate of patients with septic shock, and the smooth curve fitting graph was used to verify its relationship with net fluid intake and death. Results:There were 241 cases in the survival group and 67 cases in the death group. Univariate COX analysis showed statistically significant differences between the survival and death groups in acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) ( P=0.0006), red cell volume distribution width (RDW) ( P=0.0043), age ( P=0.0184), ΔHCT d2-d1 ( P=0.0136), ΔHCT d3-d1 ( P=0.0204), and white blood cell (WBC) ( P=0.0444). Multivariate COX analysis showed that ΔHCT d2-d1 ( P=0.0115) and ΔHCT d3-d1 ( P=0.0029) were independent risk factors for death in EICU patients with septic shock. ΔHCT d2-d1 and ΔHCT d3-d1 were divided into three groups according to the three-digit method. The Kaplan-Meier survival curve showed no significant difference among the three groups in the overall survival rate related to ΔHCT d2-d1 ( P=0.16), but there was a statistically significant difference in the overall survival rate among the three groups related to ΔHCT d3-d1 ( P=0.025). The smooth fitting curve of ΔHCT d3-d1, net fluid intake, and prognosis showed that ΔHCT d3-d1 was negatively correlated with net fluid intake, and the middle ΔHCT d3-d1 group had the best prognosis. Conclusions:The value of ΔHCT d3-d1 is related to the net fluid intake of patients with septic shock. An appropriate decrease in HCT on the third day can improve the prognosis of patients with septic shock. The dynamic changes of hematocrit can provide a certain basis for fluid resuscitation and prognosis evaluation in patients with septic shock.

Objective: To investigate the adverse reactions of resin cement used for dentin bonding and its influencing factors. Methods: Patients with dental defects treated with resin cement dentin adhesive for direct composite resin repair or full crown indirect repair were selected as the research objects. The occurrence and causes of adverse reactions, such as dental pulp lesions, soft tissue adverse reactions, and restoration loosening and falling off 7 days, 1 month, 3 months, 6 months, and 1 year after treatment, were analyzed retrospectively. Results : Among the 14 776 teeth of 5 971 patients who used resin cement dentin adhesive, 580 cases (3.93%) had adverse reactions. Univariate analysis showed that the incidence of adverse events was highest in teeth with the "full crowns (fixed partial dentures)" restoration type at 7 days, 1 month, and 12 months after treatment. At 7 days after treatment, the incidence of adverse events was the highest in teeth with a preparation depth of "near pulp after preparation". At 7 days and 3 months after treatment, the incidence of adverse events was the highest in teeth with " dentin conditioner-adhesive-resin" treatment of the bonding surface. Multivariate analysis indicated that pulp perforation and pulp capping after tooth preparation were risk factors for adverse events 7 days after treatment (OR=2.610), and the “dentin primer-adhesive-resin” bonding surface treatment method was a protective factor for adverse events 7 days and 3 months after treatment (OR<1). Conclusion affect the occurrence of adverse events. pulp perforation, and pulp capping after tooth preparation, and self-etching bonding may contribute to adverse reactions.

Objective: To investigate the effect of the socket-shield technique (SST) concurrent with immediate implant placement and provisionalization (IIPP) in the aesthetic restoration of anterior teeth. Methods: A case of maxillary anterior tooth stumps with a thin labial bone wall was treated with SST for preservation of labial soft and hard tissue fullness, combined with an immediate implant placement and immediate provisional crown for restoring the shape of the tooth and gingival molding Results: Immediate implant placement and provisionalization restored the morphology and function of the affected tooth in the shortest possible time. The patient's labial soft and hard tissue contours in the affected tooth area were well preserved in the 18-month follow-up after the application of the SST, which presented a better aesthetic result. The literature review indicates that the indications for SST are unrestorable maxillary anterior teeth, whose dental, periodontal and periapical tissues are healthy and intact. In the esthetic zone, root shielding is effective in maintaining the soft and hard tissue contour on the labial side of the implant. However, there is no consensus on the technical details of SST, such as the ideal coronal height and thickness of the shield, and the management of the gap between the shield and the implant. Thus, more clinical studies and histologic evidence are needed to provide a reference for clinical decision-making. In addition, digital technology can improve the accuracy of implant placement and shield preparation. Conclusion The correct application of SST combined with IIPP in the esthetic zone can ensure esthetic results. However, more high-quality evidence-based medical evidence is needed for its long-term efficacy, and indications should be strictly controlled during clinical application.

Objective: To explore an accurate method to obtain an intraoral model of patients with specific limited mouth opening (microstomia) due to systemic scleroderma. Methods: This study followed medical ethics, and informed consent has been obtained from patients. A case of Ken's Type I mandibular dentition defect scleroderma with limited mouth opening was addressed with digital technology as the leading method combined with the traditional impression method of segmental impression. Individual trays were made based on the patient's left and right mandibular dentition, and segmented molds were obtained. Simultaneously, intraoral scanning was performed to obtain the morphological data of both the soft and hard tissues of the upper and lower mandibles. After each part of the model was obtained, the mandibular model was scanned and digitally aligned to form the final denture model, and the final removable partial denture was designed and made by computer aided design/computer aided manufacturing (CAD/CAM) technology. At the same time, combined with the literature, the diagnosis and treatment of removable partial denture in patients with limited mouth opening were retrospectively analyzed. Results: The denture was well retained and achieved a good repair effect. The patients expressed satisfaction with the mastication efficiency and other functions of the denture. The findings of the literature review show that the integration of digital technology with the traditional impression method, along with computer fitting, can accurately obtain the patient's oral model and facilitate successful follow-up repairs. However, when the anterior mandibular dentition of the patient is absent, the margin of error is increased in this procedure, which deserves further exploration. Conclusion Utilizing digital technology as the leading method, combined with the traditional impression method of segmental impression, for the repair of dental defects in patients with limited mouth opening, has proven to be effective. Thus, patients report a positive medical experience with high satisfaction, indicating that this approach is worthy of clinical promotion.
