To discuss the effect of varicella vaccination on the clinical characteristics of herpes zoster (shingles) cases aged 20 years and under, and analyze its clinical features. Based on the Yichang Health Big Data Platform, a descriptive study was conducted to collect the information of cases aged 20 years and under in three medical institutions of Yichang Central People's Hospital, Yichang First People's Hospital and Yichang Second People's Hospital from March 2019 to September 2020. According to the history of varicella vaccine, cases were divided into vaccination group and non-vaccination group, and their clinical features and outcomes were compared. The results showed that 46 shingles cases, aged from 7 to 20 years old, were included in this study. 26 males (56.5%), 20 females (43.5%), 15 cases in vaccination group (32.6%) and 31 cases in non-vaccination group (67.4%). 28 cases had thoracic involvement, followed by lumbar (n=8), cranial (n=7) involvements and extremities (n=7). The spread of herpes skin area: 2 cases involved too large area, 21 cases of 10 cm×10 cm, 14 cases of 5 cm×5 cm, 9 cases of 1 cm×1 cm. Herpes number: 26 cases had 10-49 herpes, followed by <10 herpes (n=9), uncountable herpes (n=7) and 50-99 herpes (n=4). The clinical course[M(Q₁,Q₃)] lasted 20.5 (13.5,24.8) d averagely, 5 cases had postherpetic neuralgia (PHN) and 1 case had respiratory complications. Shingles decrustation time was significantly shorter in vaccination group (Z=-2.01, P<0.05), and there was no significant difference in other characteristics by vaccination. In conclusion, the number and spread of shingles in most children and adolescents are less, and the complications such as PHN are less. Varicella vaccination can reduce the decrustation time and relieve shingles cases with some clinical symptoms.

ObjectiveTo investigate the protective effect of Danggui Shaoyaosan （DSS）-contained serum on β-amyloid （Aβ）_1-40-injured rat adrenal pheochromocytoma PC12 cells and its mechanism in regulating ubiquitin-proteasome pathway （UPP）. MethodAβ_1-40 was used to intervene PC12 cells to prepare the cell models of Alzheimer's disease （AD）， and the experiment was divided into the blank， model， and DSS-contained serum high， medium， and low-dose groups （10%， 5%， and 2.5%）. Cell viability and apoptosis were detected using cell counting kit-8 （CCK-8） method and flow cytometry， respectively. The content of Aβ and p-Tau protein was determined by enzyme-linked immunosorbent assay （ELISA）. The ubiquitin （Ub）， ubiquitin ligase E3 （E3）， 26S proteasome， ubiquitin carboxyl terminal hydrolase1 （UCHL1）， and UCHL3 protein expressions of UPP were displayed using immunofluorescence cytochemistry （ICC）， and the mRNA and protein expression levels of Ub， E3-parkin， 26S， UCHL1， and UCHL3 were determined by real-time fluorescent quantitative polymerase chain reaction （Real-time PCR） and Western blot， respectively. ResultThe data of the CCK8 experiment verified that 5 μmol·L^-1 and 48 hours were the optimal conditions for modeling Aβ_1-40-injured PC12 cells. As compared with the blank group， the cell viability rate in the model group decreased （P<0.05） with an increased apoptosis rate （P<0.05）， the content of Aβ and p-Tau contents was elevated （P<0.05）， the mRNA and protein expression levels of Ub increased， and the mRNA and protein expression levels of 26S， E3， and UCHL1+3 decreased （P<0.05）. As compared with the model group， the cell viability rate in the DSS-contained medium-dose group increased （P<0.05）， whereas the apoptosis rate in each DSS-contained group decreased （P<0.05）. The content of Aβ in each DDS-contained group decreased （P<0.05）， and the content of p-Tau in the DDS-contained high and medium-dose groups decreased （P<0.05）. The mRNA expression level of Ub decreased， and that of 26S increased in each DDS-contained group （P<0.05）. The mRNA expression level of UCHL1 in the DDS-contained medium-dose group increased （P<0.05）， and the mRNA expression levels of E3 and UCHL 3 in the DDS-contained high and medium-dose groups increased （P<0.05）. The protein expression level of Ub in each DDS-contained group decreased， and the protein expression levels of 26S， E3， and UCHL1+3 in the DDS high and medium-dose groups increased. The DSS-contained serum medium-dose group exerted the optimal effect. ConclusionDSS-contained serum can increase cell viability rate， reduce cell apoptosis rate， eliminate Aβ and p-Tau protein deposits， and exert protective effects on Aβ_1-40-injured PC12 cells. Its mechanism may involve UPP via decreasing the expression of Ub and increasing that of 26S， E3， UCHL1， and UCHL3.

OBJECTIVE: To evaluate the effect of two barrier membranes [multilaminated small intestinal submucosa (mSIS) and bioresorable collagen membrane (Bio-Gide)] combined with deproteinized bovine bone mineral Bio-Oss on guided bone regeneration through a canine extraction sockets model. METHODS: The distal roots of 18 premolars of the Beagle' s bilateral maxillary and mandibular were removed, and 18 extraction sockets were obtained. They were randomly divided into 3 groups, and the following procedures were performed on the sockets: (1) filled with Bio-Oss and covered by mSIS (mSIS group), (2) filled with Bio-Oss and covered by Bio-Gide (BG group), (3) natural healing (blank control group). Micro-computed tomograph (Micro-CT) was performed 4 and 12 weeks after surgery to eva-luate the new bone regeneration in the sockets of each group. RESULTS: The postoperative healing was uneventful in all the animals, and no complications were observed through the whole study period. Micro-CT analysis showed that the new bone fraction in the mSIS group and the BG group was significantly higher than that in the blank control group at the end of 4 weeks and 12 weeks (P < 0.05), and more new bone fraction was observed in the mSIS group than in the BG group, but the difference was not statistically significant (P>0.05). The new bone fraction of coronal third part of the socket in the mSIS group and BG group at the end of 4 weeks were significantly higher than that of the middle and apical third part of each group (P < 0.05). The values of bone mineral density were similar at 4 weeks in all the groups (P>0.05), but were significantly higher than that in the control group at the end of 12 weeks (P < 0.05). The bone morphometric analysis showed that the trabecular number and trabecular spacing were significantly better in the mSIS group and the BG group than in the control group at the end of 4 weeks and 12 weeks (P < 0.05), while the value in the mSIS group was slightly higher than in the BG group, but the difference was not statistically significant (P>0.05). The difference in trabecular thickness between all the groups was not statistically significant (P>0.05). CONCLUSION mSIS membrane as a barrier membrane combined with deproteinized bovine bone mineral can enhance new bone formation in canine extraction sockets, similar to Bio-Gide collagen membrane.

OBJECTIVE: To examine the morphology and biocompatibility of a native acellular porcine pericardium (APP) in vitro and to evaluate its barrier function and effects on osteogenesis when used in guided bone regeneration (GBR) in vivo. METHODS: First, the morphology of APP (BonanGen^Ⓡ) was detected using a scanning electron microscope (SEM). Next, for biocompatibility test, proliferation of human bone marrow mesenchymal stem cells (hBMSCs) were determined using cell counting kit-8 (CCK-8) after being seeded 1, 3 and 7 days. Meanwhile, the cells stained with phalloidine and 4, 6-diamidino-2-phenylindole (DAPI) were observed using a confocal laser scanning microscopy (CLSM) to view the morphology of cell adhesion and pattern of cell proliferation on day 5. A 3-Beagle dog model with 18 teeth extraction sockets was used for the further research in vivo. These sites were randomly treated by 3 patterns below: filled with Bio-Oss^Ⓡand coverd by APP membrane (APP group), filled with Bio-Oss^Ⓡand covered by Bio-Gide^Ⓡmembrane (BG group) and natural healing (blank group). Micro-CT and hematoxylin-eosin (HE) were performed after 4 and 12 weeks. RESULTS: A bilayer and three-dimensional porous ultrastructure was identified for APP through SEM. In vitro, APP facilitated proliferation and adhesion of hBMSCs, especially after 7 days (P < 0.05). In vivo, for the analysis of the whole socket healing, no distinct difference of new bone ratio was found between all the three groups after 4 weeks (P>0.05), however significantly more new bone regeneration was detected in APP group and BG group in comparison to blank group after 12 weeks (P < 0.05). The radio of bone formation below the membrane was significantly higher in APP group and BG group than blank group after 4 and 12 weeks (P < 0.05), however, the difference between APP group and BG group was merely significant in 12 weeks (P < 0.05). Besides, less resorption of buccal crest after 4 weeks and 12 weeks was observed in APP group of a significant difference compared in blank group (P < 0.05). The resorption in BG group was slightly lower than blank group (P>0.05). CONCLUSION APP showed considerable biocompatibility and three-dimentional structure. Performing well as a barrier membrane in the dog alveolar ridge preservation model, APP significantly promoted bone regeneration below it and reduced buccal crest resorption. On the basis of this study, APP is a potential osteoconductive and osteoinductive biomaterial.

OBJECTIVE: To study the effect of early continuous blood purification (CBP) on the prognosis of children with septic shock. METHODS: A prospective analysis was performed for the children with septic shock who did not reach the 6-hour initial recovery target and/or had a fluid overload of >10%. According to the treatment time of CBP, they were divided into an early group with 30 children and a conventional group with 28 children. The two groups were compared in terms of the start time of CBP and 28-day mortality rate, as well as the related indexes in the children who were cured. RESULTS: The early group had a significantly earlier start time of CBP than the conventional group (P<0.05). There were 25 children cured in the early group and 22 cured in the conventional group, and there was no significant difference in 28-day mortality rate between the two groups (P>0.05). The children who were cured in the early group had significantly shorter correction time of lactic acid, urine volume, and fluid overload than those in the conventional group (P<0.05). The children who were cured in both groups had significant reductions in the percentages of T-lymphocyte subsets at the beginning (P<0.05); on reexamination on day 7, the percentages of T-lymphocyte subsets were increased and were higher in the early group than in the conventional group (P<0.05). The children who were cured in the early group had significantly shorter duration of CBP treatment, duration of mechanical ventilation, and length of stay in the PICU than those in the conventional group (P<0.05). CONCLUSIONS For children with septic shock who do not reach the 6-hour initial recovery target and/or have a fluid overload of >10%, early CBP treatment can quickly control the disease, shorten the course of disease, and accelerate immune reconstruction.

BACKGROUND: Renal artery stenosis (RAS) is always associated with abnormalities in renal microvascular perfusion (RMP). However, few imaging methods can simultaneously evaluate the degree of luminal stenosis and RMP. Thus, this study will aim to evaluate the feasibility of using contrast-enhanced ultrasound (CEUS) for assessing both RAS and RMP to achieve a one-stop assessment of patients with suspected renovascular hypertension. METHODS: This will be a single-center diagnostic study with a sample size of 440. Patients with chronic kidney disease (CKD) and suspected of having resistant hypertension will be eligible. Patients with Stages 1-3 CKD will undergo CEUS and computed tomography (CT) angiography (CTA). Values obtained by CEUS and CTA for diagnosing low-grade (lumen reduced by <60%) and high-grade (lumen reduced by ≥60%) RAS will be compared. Moreover, all patients will also undergo radionuclide imaging. The diagnostic value for RAS will be assessed by the receiver operating characteristic curve, including the accuracy, sensitivity, specificity, positive predictive values, negative predictive values, and area under the ROC. Pearson correlation analysis will be performed to assess the association between CEUS findings for RMP and glomerular filtration rate measured by a radionuclide imaging method. CONCLUSION: The data gathered from this study will be used to evaluate the feasibility of expanding clinical applications of CEUS for evaluation of patients with suspected renovascular hypertension.
