ABSTRACT

ObjectiveTo explore the therapeutic effect of Huangliansan on atopic dermatitis (AD) model mice induced by 2, 4-dinitrochlorobenzene (DNCB). MethodA total of 42 male BALB/c mice were randomly divided into normal group, model group, hydrocortisone group, low, medium, and high-dose groups (0.3, 0.6, 1.2 g·kg-1) of Huangliansan oil, and water extract group (0.6 g·kg-1) of Huangliansan. In addition to the normal group, DNCB was applied on the back of mice in other groups to establish the AD model. On the 15th day after DNCB stimulation, each group was given the corresponding drug or solvent, and the changes in skin lesions, dermatitis score, and frequency of scratching were observed and recorded. Hematoxylin-eosin (HE) staining was used to observe the histopathological changes in the skin and spleen. Real-time fluorescent quantitative polymerase chain reaction (Real-time PCR) was used to detect mRNA levels of filaggrin (FLG), lorophane (LOR), and involucrin (IVL) in skin, as well as immunoglobulin E (lgE), interleukin-4 (IL-4), interleukin-6 (IL-6), interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), and interferon-γ (IFN-γ) in spleen. ResultCompared with the normal group, the model group showed symptoms of skin swelling and scab, and the score of dermatitis, the frequency of scratching, and the spleen index were increased (P<0.05). The expression levels of FLG, LOR, and IVL in skin tissue were significantly decreased (P<0.01), and the mRNA expressions of IgE, IL-4, IL-6, IL-1β, and TNF-α in the spleen were significantly increased, while the expression level of IFN-γ was significantly decreased (P<0.01). Compared with the model group, the symptoms of skin erythema, scaly, and scab of mice in each drug group were alleviated to varying degrees, and the score of dermatitis, the frequency of scratching, and the spleen index were decreased (P<0.05, P<0.01). In addition, the expression levels of FLG, LOR, and IVL in the skin of mice in the drug group were increased (P<0.05, P<0.01), and the mRNA expression of IgE, IL-4, IL-6, IL-1β, and TNF-α in spleen were decreased. IFN-γ was increased (P<0.05, P<0.01), and the lesions of the skin and spleen were improved to varying degrees. The medium-dose group of Huangliansan oil and hydrocortisone group had the most obvious manifestations (P<0.05, P<0.01). The indexes in the medium-dose group of Huangliansan oil were better than those in the water extract group of Huangliansan. ConclusionHuangliansan may improve the expression level of skin barrier protein, inhibit the expression of helper T cell 2 (Th2)-related inflammatory factors, increase the expression of helper T cell 1 (Th1) inflammatory factors, restore the skin barrier function and Th1/Th2 balance in the spleen, regulate the inflammatory response in the spleen of AD mice, and thus relieve AD. Huangliansan oil is more effective than water extract.

ABSTRACT

Objective: To investigate the misdiagnosis of area postrema syndrome (APS) manifesting as intractable nausea, vomiting and hiccups in neuromyelitis optic spectrum disease (NMOSD) and reduce the risk of misdiagnosis. Methods: We retrospectively analyzed data from NMOSD patients attending the Department of Neurology at the First Medical Center of PLA General Hospital between January 2019 and July 2021. SPSS25.0 was then used to analyze the manifestations, misdiagnosis, and mistreatment of APS. Results: A total of 207 patients with NMOSD were included, including 21 males and 186 females. The mean age of onset was 39±15 years (range: 5-72 years). The proportion of patients who were positive for serum aquaporin 4 antibody was 82.6% (171/207). In total, 35.7% (74/207) of the NMOSD patients experienced APS during the disease course; of these patients, 70.3% (52/74) had APS as the first symptom and 29.7% (22/74) had APS as a secondary symptom. The misdiagnosis rates for these conditions were 90.4% (47/52) and 50.0% (11/22), respectively. As the first symptom, 19.2% (10/52) of patients during APS presented only with intractable nausea, vomiting and hiccups; 80.8% (42/52) of patients experienced other neurological symptoms. The Departments of Gastroenterology and General Medicine were the departments that most frequently made the first diagnosis of APS, accounting for 54.1% and 17.6% of patients, respectively. The most common misdiagnoses related to diseases of the digestive system and the median duration of misdiagnosis was 37 days. Conclusions: APS is a common symptom of NMOSD and is associated with a high rate of misdiagnosis. Other concomitant symptoms often occur with APS. Gaining an increased awareness of this disease/syndrome, obtaining a detailed patient history, and performing physical examinations are essential if we are to reduce and avoid misdiagnosis.

ABSTRACT

To explore whether PPARA is involved in the process of ferroptosis in hepatoma cells, peroxisome proliferator activated receptor (PPARA) was comprehensively analyzed in hepatocellular carcinoma (HCC) through public database and experimental data, including the expression, the functions and the potential roles of tumor progression. The research design is experimental research,data analysis based on bioinformatics and cell experiment. From January 2022 to August 2022, relevant cell experiments were conducted in the Basic Medical Laboratory of the General Hospital of the Southern Theatre of the Chinese People's Liberation Army. The expression and the correlation with clinicopathologic features of PPARA in HCC were analyzed by The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases. To study the protein expression of PPARA in HCC and normal tissues through the Human Protein Atlas (HPA). The protein-protein interaction (PPI) network between PPARA and the core factor of ferroptosis was constructed based on Search Tool for the Retrival of Interacting Genes/Protein (STRING) database, then, the correlation between PPARA and the core gene Glutamate-cysteine Ligase Catalytic Subunit (GCLC) was analyzed by Gene Expression Profiling Interactive Analysis (GEPIA). Assessed the expression of PPARA in HCC cell lines SK-HEP-1, SMMC-7721, MHCC-97H, BEL-7402 and normal liver cell L02 by Western Blot (WB) and the changes of PPARA expression after 48h treatment with ferroptosis inducer Erastin were observed. Single factor analysis of variance was used to compare the expression of PPARA between groups in GEPIA database. The expression of PPARA in GSE25097 and GSE112790 data was compared by rank sum test. Survival analysis was performed using time series test method. The difference of PPARA expression between clinical and pathological features was compared using the Kruskal-Wallis test. The correlation between the expression of GCLC and PPARA was compared by the method of Spearman correlation. The expression of PPARA in cell lines was compared by paired T test. The results showed that the RNA and protein expression of PPARA in HCC was lower than that in normal tissues (P<0.05). PPARA alterations were correlated with patient clinicopathological features and prognosis (P<0.05). The PPI constructed by STRING database suggests that PPARA interact with the key factors of ferroptosis, such as NFE2 like bZIP transcription factor 2 (NFE2L2), Heme Oxygenase 1 (HMOX1), Tumor Protein P53 (TP53), GCLC, Dipeptidyl Peptidase 4 (DPP4), Citrate Synthase (CS), Arachidonate 15-Lipoxygenase (ALOX15) and Acyl-CoA Synthetase Long Chain Family Member 4 (ACSL4). Furthermore, the PPARA was significantly associated with GCLC validated via GEPIA database(R=0.6, P<0.05). The expression of PPARA increased after treatment with ferroptosis inducer Erastin for 48 h by WB. In conclusion, the expression of PPARA is lower in HCC with a poor prognosis. PPARA interacts with GCLC in regulating ferroptosis in HCC.

ABSTRACT

Objective: Analysis and investigation of pathogenic characteristics of polymyxin-and carbapenem-resistant Klebsiella pneumoniae (PR-CRKP). Methods: A total of 23 PR-CRKP strains isolated from clinical specimens from the General Hospital of Southern Theater Command from March 2019 to July 2021 were retrospectively collected, Whole-genome sequencing was performed on 23 PR-CRKP strains, resistance genes were identified by comparison of the CARD and the ResFinder database, high-resolution typing of PR-CRKP strains was analyzed by core genomic multilocus sequencing (cgMLST) and single nucleotide polymorphism (SNP); polymyxin resistance genes were determined by PCR and sequencing. Results: All PR-CRKP strains were KPC-2 producing ST11 types. cgMLST results showed that the evolutionary distance between the PR-CRKP strains and Klebsiella pneumoniae in mainland China was 66.44 on average, which is more closely related than foreign strains; the 23 PR-CRKP strains were divided into 3 main subclusters based on SNP phylogenetic trees, with some aggregation among Clade 2-1 in the isolation department and date. The two-component negative regulatory gene mgrB has seven mutation types including point mutations, different insertion fragments and different insertion positions. Conclusion: The close affinity of PR-CRKP strains indicate the possibility of nosocomial clonal transmission and the need to strengthen surveillance of PR-CRKP strains to prevent epidemic transmission of PR-CRKP.

ABSTRACT

Objective@#To explore the effectiveness of the comprehensive intervention on prevention of deciduous primary caries in 3-year-old children, so as so provide reference for the prevention, health care and treatment of oral caries.@*Methods@#Three-year-old children selected by drawing lots from 10 public kindergartens in 5 districts of Bengbu were examined in 2021, and were randomly divided into intervention group ( n =300) and control group ( n =300). During the initial examination, caries loss (dmf) including dental caries, missing teeth, filling teeth were assessed in the two groups. At the initial examination, the intervention group received caries intervention while no intervention was administered in the non-intervention group until half a year later. Intervention measures included education, diet, self-cleaning and fluoride application intervention. The number of cases and the mean of caries loss in the two groups were compared by χ 2 test.@*Results@#Before the intervention, 43 children in the control group suffered from caries, with 88 dmf, including 44 dmf for boys and 44 dmf for girls. There were 45 children in the intervention group, with 101 dmf, including 49 dmf for boys and 52 dmf for girls. There was no significant difference in the number of dmf between the intervention group and the control group ( χ 2=0.91, P >0.05), and there was no significant difference in the prevalence rate (15.0%, 14.3%, χ 2=0.05, P >0.05). After the intervention, there were 26 new dental caries and 43 dmf in intervention group, including 25 dmf for boys and 18 dmf for girls. In the control group, there were 83 new dental caries and 168 dmf, including 72 dmf for boys and 96 dmf for girls. Compared with the control group, the new dmf in the intervention group was significantly different ( χ 2=75.38, P < 0.05). The number of new dental caries patients in the intervention group was significantly different from that in the control group ( χ 2=36.42, P <0.05).@*Conclusion@#Comprehensive interventions to prevent dental caries can significantly reduce the incidence of primary teeth caries in children. It is suggested to intervene dental caries as early as possible to reduce the incidence of dental caries and other oral diseases.

ABSTRACT

OBJECTIVES@#To examine the reliability and accuracy of Walker's model for estimating the sex of Han adults in western China by using cranium three-dimensional (3D) CT reconstruction, and to study the suitable cranial sex estimation model for Han people in western China.@*METHODS@#A total of 576 cranial CT 3D reconstructed images from Hanzhong Hospital in Shaanxi Province from 2017 to 2021 were collected. These images were divided into the experimental group with 486 samples and the validation group with 90 samples. Walker's model was used by observer 1 to estimate the sex of experimental group samples. The logistic function applicable to Han people in western China was corrected by observer 1. The 90 samples in the validation group were scored and substituted into the modified logistic function to complete the back substitution test by observer 1, 2 and 3.@*RESULTS@#The accuracy of sex estimation of Han adults in western China was 63.2%-77.2% by applying Walker's model. The accuracy of modified logistic function was 82.9%. The accuracy of sex estimation through back substitution test by 3 observers was 75.6%-91.1%, with a Kappa value of 0.689 (P<0.05) for inter-observer consistency and 0.874 (P<0.05) for intra-observer consistency.@*CONCLUSIONS@#There are great differences in bone characteristics among people from different regions. The modified logistic function can achieve higher accuracy in Han adults in western China.

ABSTRACT

OBJECTIVE@#To investigate the effect and underlying mechanism of hispidulin on the proliferation and apoptosis of leukemia K562 cells.@*METHODS@#K562 cells were cultured in vitro and treated with 0, 5, 25 or 100 μmol/L hispidulin for 24 h. Cell proliferation and apoptosis were detected by CCK-8 and flow cytometry, respectively. Western blot was used to assess the expression of Bax, Bcl-2 and interleukin (IL)-37 proteins. Bone marrow mononuclear cells were extracted from 17 chronic myeloid leukemia patients and 21 healthy individuals by Ficoll-Hypaque density gradient method, and the expression of IL-37 protein was measured by Western blot. K562 cells with IL-37 overexpression or knockdown were constructed, and then treated with 0 or 100 μmol/L hispidulin for 24 h. Cell proliferation, apoptosis and protein expression of Bax and Bcl-2 were determined in the same way as above.@*RESULTS@#After K562 cells were treated with hispidulin, the cell inhibition rate, apoptosis rate, and the protein expression of Bax and IL-37 were significantly increased (P <0.05), but the cell proliferation and expression of Bcl-2 protein were decreased (P <0.05). The expression of IL-37 protein in bone marrow mononuclear cells of the leukemia patient was 0.24±0.03, which was significantly lower than 0.91±0.05 of healthy controls (P <0.05). Overexpression of IL-37 significantly promoted inhibition rate, apoptosis rate, and expression of Bax protein in K562 cells (P <0.05), but suppressed the expression of Bcl-2 protein (P <0.05). In addition, knockdown of IL-37 could reverse the effects of hispidulin on proliferation and apoptosis of K562 cells.@*CONCLUSION@#Hispidulin inhibits the proliferation and induces apoptosis of leukemia K562 cells, which may be related to the up-regulation of IL-37 protein in cells.

ABSTRACT

OBJECTIVE@#To detect the expression level of HK2 gene in the bone marrow of newly diagnosed patients with acute myeloid leukemia (AML) and investigate its influence on the clinical characteristics and prognosis.@*METHODS@#The expression level of HK2 gene in the bone marrow of 90 newly diagnosed patients with AML that accompanying clinical characteristics and survival status were detected by RT-qPCR, and compared with 18 allogeneic hematopoietic stem cell transplantation (allo-HSCT) donors. The Chi-square test, Kaplan-Meier survival analysis, and Cox proportional hazards regression model were used to analyze the correlation of HK2 expression level with clinical characteristics and prognosis.@*RESULTS@#Compared with allo-HSCT donors, the HK2 expression was significantly increased in newly diagnosed AML patients (P <0.01). Compared with patients with total response (OR, complete response + complete response with incomplete hematologic recovery) after 2 courses of induction chemotherapy, the expression of HK2 in patients without OR was significantly increased (P <0.05). There was a significant difference in the relative expression of HK2 between patients with and without OR after 2 courses of induction therapy (P <0.001). The median survival time of patients with high expression of HK2 was significantly shorter than that of patients with low expression of HK2 (P <0.05). The multivariate Cox proportional hazards regression analysis showed that prognostic stratification, the expression level of HK2, and whether two courses of induction therapy achieved OR were independent factors affecting the prognosis of AML patients (P <0.05).@*CONCLUSIONS@#Compared with allo-HSCT donors, the expression level of HK2 gene is increased in the bone marrow of newly diagnosed AML patients. The prognosis of patients with high expression of HK2 is poor. The expression level of HK2 is an independent factor affecting the prognosis of AML patients.

ABSTRACT

Dao-di herbs are the treasure of Chinese materia medica and one of the characteristic research objects of traditional Chinese medicine(TCM). Probing into the microevolution of Dao-di herbs can help to reveal their biological essence and quality formation mechanisms. The progress in molecular biology and omics provides the possibility to elucidate the phylogenetic and quality forming characteristics of Dao-di herbs at the molecular level. In particular, genomics serves as a powerful tool to decipher the genetic origins of Dao-di herbs, and molecular markers have been widely used in the research on the genetic diversity and population structure of Dao-di herbs. Focusing on the excellent traits and quality of Dao-di herbs, this paper reviews the studies about the microevolution process of quality formation mechanisms of Dao-di herbs with the application of molecular markers and omics, aiming to underpin the protection and utilization of TCM resources.

ABSTRACT

OBJECTIVE@#To investigate the treatment outcome of laparoscopic partial nephrectomy in the patients with renal tumors of moderate to high complexity (R.E.N.A.L. score 7-10).@*METHODS@#In the study, 186 patients with a renal score of 7-10 renal tumors who underwent laparoscopic partial nephrectomy in Peking University Third Hospital from February 2016 to April 2021 were selected. Laparoscopic partial nephrectomy was performed after examination. The patients were followed-up, and their postoperative hemoglobin, creatinine, complications, and length of hospital stay recorded. The data were represented by mean±standard deviation or median (range).@*RESULTS@#There were 128 males and 58 females in this group, aged (54.6±12.8) years, with body mass index of (25.4 ± 3.4) kg/m2; The tumors were located in 95 cases on the left and 91 cases on the right, with maximum diameter of (3.1±1.2) cm. The patient's preoperative hemoglobin was (142.9±15.8) g/L, and blood creatinine was 78 μmol/L (47-149 μmol/L). According to preoperative CT images, the R.E.N.A.L. score was 7 points for 43 cases, 8 points for 67 cases, 9 points for 53 cases, and 10 points for 23 cases. All the ope-rations were successfully completed, with 12 cases converted to open surgery. The operation time was 150 minutes (69-403 minutes), the warm ischemic time was 25 minutes (3-60 minutes), and the blood loss was 30 mL (5-1 500 mL). There were 9 cases of blood transfusions, with a transfusion volume of 800 mL (200-1 200 mL). Postoperative hemoglobin was (126.2±17.0) g/L. The preoperative crea-tinine was 78 μmol/L (47-149 μmol/L), the postoperative creatinine was 83.5 μmol/L (35-236 μmol/L), the hospital stay was 6 days (3-26 days), and surgical results achieved "the trifecta" in 87 cases (46.8%). In the study, 167 cases were followed up for 12 months (1-62 months), including 1 case with recurrence and metastasis, 4 cases with metastasis, and 2 cases with other tumors (1 case died).@*CONCLUSION@#Laparoscopic partial nephrectomy is safe and effective in the treatment of renal tumors with R.E.N.A.L. score of 7-10. Based on the complexity of the tumor, with the increase of difficulty, the warm ischemia time and operation time tend to increase gradually, while "the trifecta" rate gradually decreases. The complications of this operation are less, and the purpose of preserving renal function to the greatest extent is achieved.

ABSTRACT

OBJECTIVE@#To study the effectiveness and feasibility of cryogenic disinfectants in different cold scenarios and analyze the key points of on-site cryogenic disinfection.@*METHODS@#Qingdao and Suifenhe were selected as application sites for the manual or mechanical spraying of cryogenic disinfectants. The same amount of disinfectant (3,000 mg/L) was applied on cold chain food packaging, cold chain containers, transport vehicles, alpine environments, and article surfaces. The killing log value of the cryogenic disinfectant against the indicator microorganisms ( Staphylococcus aureus and Escherichia coli) was used to evaluate the on-site disinfection effect.@*RESULTS@#When using 3,000 mg/L with an action time of 10 min on the ground in alpine regions, the surface of frozen items, cold-chain containers, and cold chain food packaging in supermarkets, all external surfaces were successfully disinfected, with a pass rate of 100%. The disinfection pass rates for cold chain food packaging and cold chain transport vehicles of centralized supervised warehouses and food processing enterprises were 12.5% (15/120), 81.67% (49/60), and 93.33% (14/15), respectively; yet, the surfaces were not fully sprayed.@*CONCLUSION@#Cryogenic disinfectants are effective in disinfecting alpine environments and the outer packaging of frozen items. The application of cryogenic disinfectants should be regulated to ensure that they cover all surfaces of the disinfected object, thus ensuring effective cryogenic disinfection.

ABSTRACT

Objective: To examine the safety and effectiveness of inflatable video-assisted mediastinoscopic transhiatal esophagectomy (IVMTE). Methods: Totally 269 patients admitted to the Anhui Provincial Hospital of Anhui Medical University who underwent IVMTE (IVMTE group, n=47) or thoracoscopy combined with minimally invasive Mckeown esophageal cancer resection (MIME group, n=222) from September 2017 to December 2021 were analyzed retrospectively. There were 31 males and 16 females in IVMTE group, aged (68.6±7.5) years (range: 54 to 87 years). There were 159 males and 63 females in MIME group, aged (66.8±8.8) years (range: 42 to 93 years). A 1∶1 match was performed on both groups by propensity score matching, with 38 cases in each group. The intraoperative conditions and postoperative complication rates of the two groups were compared by t test, Wilcoxon rank, χ2 test, or Fisher exact probability method. Results: Patients in IVMTE group had less intraoperative bleeding ((96.0±39.2) ml vs. (123.8±49.3) ml, t=-2.627, P=0.011), shorter operation time ((239.1±47.3) minutes vs. (264.2±57.2) minutes, t=-2.086, P=0.040), and less drainage 3 days after surgery (85(89) ml vs. 675(573) ml, Z=-7.575, P<0.01) compared with that of MIME group. There were no statistically significant differences between the two groups in terms of drainage tube-belt time, postoperative hospital stay, and lymph node dissection stations and numbers (all P>0.05). The incidence of Clavien-Dindo grade 1 to 2 pulmonary infection (7.9%(3/38) vs. 31.6%(12/38), χ²=6.728, P=0.009), total complications (21.1%(8/38) vs. 47.4%(18/38), χ²=5.846, P=0.016) and total lung complications (13.2%(5/38) vs. 42.1%(16/38), χ²=7.962, P=0.005) in the IVMTE group were significantly lower. Conclusion: Inflatable video-assisted mediastinoscopic transhiatal esophagectomy combined with laparoscopic esophagectomy is safe and feasible, which can reach the same range of oncology as thoracoscopic surgery.

ABSTRACT

Objective:To observe any stimulatory effect of intermittent theta burst stimulation (iTBS) on the cerebral swallowing cortex and the cerebellar swallowing motor area and to explore the related mechanisms.Methods:Forty-four healthy right-handed subjects were divided at random into a dominant cerebellum group ( n=15), a non-dominant cerebellum group ( n=15) and a control group ( n=14). In the dominant cerebellum group, iTBS was administered to the cerebellum of the dominant hemisphere, and the other hemisphere was given sham stimulation. In the non-dominant cerebellum group, it was the opposite. The dominant cerebellum received the sham stimulation. In the control group both hemispheres received sham stimulation. Before and after the stimulation, single-pulse transcranial magnetic stimulation (TMS) was applied to the representative regions of suprahyoid muscles in bilateral brain and cerebellum to observe changes of the latency and amplitude of motor evoked potentials (MEPs). Results:After the intervention the MEP amplitude of the bilateral swallowing cortex and the stimulated cerebellum had increased in the non-dominant cerebellum group, with increased MEP amplitude only from the stimulated cerebellum of the dominant cerebellum group. Compared with the control group, the non-dominant cerebellum group showed the greatest improvement in MEP amplitude of the stimulated bilateral cerebral cortex and cerebellum. Improvement in the dominant cerebellum group was significantly smaller. However, there were no significant differences in MEP latency or the percentage change in MEP latency from baseline among the three groups.Conclusions:Applying iTBS to either the non-dominant or the dominant cerebellum excites the brain areas related to swallowing, but in different ways.

ABSTRACT

Objective:To learn about the cognition of iodine deficiency disorders (IDD) prevention knowledge among key population in the IDD area of Jilin Province, and to evaluate the effect of health education.Methods:From 2015 to 2019, 10 counties (cities, districts, hereinafter referred to as counties) in Jilin Province were selected as project counties every year. Public health education covered the entire project county. In each project county, 3 project townships were selected, and students of grades 4-6 were selected from the central primary schools of each project township for school health education. In each project township, 3 project villages were selected to carry out community health education. Before and after health education, 30 fifth-grade students were selected from the central primary school of each project township, and 15 housewives were selected from the vicinity of each primary school to conduct a questionnaire survey on IDD prevention knowledge.Results:After health education, the overall awareness rate of IDD prevention knowledge among primary school students and housewives in Jilin Province was 96.26% (13 324/13 842) and 96.40% (6 819/7 074), which was significantly higher than that before the intervention [65.36% (9 032/13 818) and 71.26% (5 039/7 071)], and the differences were statistically significant (χ 2 = 4 258.34, 1 647.92, P < 0.001), and the awareness rates of primary school students and housewives increased by 30.90% and 25.14%, respectively. Conclusion:Health education has significantly increased the awareness rate of IDD prevention knowledge among key populations in Jilin Province, and is an important measure to ensure the continuous elimination of IDD.

Thyroid cancer is the most common malignant tumor of the endocrine system, and its incidence is increasing year by year showing younger trend. The pathological types of thyroid cancer are papillary carcinoma, follicular carcinoma, medullary carcinoma and undifferentiated carcinoma. Medullary thyroid carcinoma (MTC) and papillary thyroid carcinoma (PTC) are the two common types of thyroid cancer. Since MTC and PTC have different biological origins, invasiveness and prognosis. Therefore, the occurrence of both medullary carcinoma and papillary carcinoma is very rare and rarely reported in China and abroad and the treatment is challenging. In this paper, we review the pathogenesis, ancillary tests, diagnosis and treatment of this disease, with the aim of providing reference for clinical treatment of patients with medullary thyroid carcinoma complicated by papillary carcinoma.

ABSTRACT

In recent years, clinical applications of robotic thyroid surgery have been gradually promoted with the continuous improvement of the da Vinci robotic surgical system. Unlike traditional open surgery, robotic thyroid surgery mainly adopts remote access, which has many advantages, such as magnified high-definition 3D view and hand vibration stabilization. The rates and causes of postoperative complications differ due to different approaches, view angles, and operation sequences. This paper presents the literature on both transoral and bilateral areolar axillary approaches in robotic thyroid surgery, focusing on five common complications under both approaches, including laryngeal recurrent nerve injury and hypoparathyroidism, to provide theoretical support for the standardization of robotic thyroid surgery.

ABSTRACT

Objective:To investigate the feasibility and advantages of unilateral primary hyperparathyroidism (PHPT) treated by transthyretal interosseous muscle approach surgery.Methods:Clinical data of 7 patients with unilateral PHPT treated by interstitial sternocleidomastoid muscle approach from Jan. 2021 to Feb. 2022 in the thyroid surgery of China-Japan Union Hospital of Jilin University were retrospectively analyzed, including preoperative blood calcium concentration, operation time, incision length, intraoperative parathyroid hormone (PTH) , blood calcium concentration and PTH value in the first month after surgery, abnormal sensation of the skin in the anterior cervical area, etc. The feasibility and advantages of interstitial sternocleidomastoid muscle approach surgery for unilateral PHPT were analyzed.Results:All 7 patients with unilateral PHPT were operated successfully. The PTH was 17.2-63.3 pg/ml on recheck 1 month after surgery, which were all within the normal range. The time from skin opening to resection of the diseased parathyroid gland was 20-35 min, and the length of the surgical incision was 3-4 cm. all patients were given intravenous and oral calcium therapy after surgery, and the blood calcium and PTH levels were within the normal range at 3-12 months of follow-up; the incision recovered well, and there was no significant sensory and functional abnormalities in the anterior neck area.Conclusion:The treatment of unilateral PHPT through the sternocleidomastoid interosseous approach can ensure the safety and efficacy of the operation while better protecting the sensory and motor functions of the anterior cervical region and improving the aesthetics of the surgical incision.

ABSTRACT

Objective To evaluate the immunoprotective effect of active immunization with recombinant peptidyl-prolyl cis-trans isomerase from Babesia microti against B. microti infection in mice. Methods Female BALB/c mice at 6 weeks of age, each weighing approximately 20 g, were divided into the recombinant protein immunization group, the infection control group and the normal control group, of 25, 18, 15 mice in each group, respectively. Mice in the recombinant protein immunization group were given active immunization with recombinant BmPPIase protein, and 18 mice with the highest antibody titers were intraperitoneally injected with 100 μL of B. microti-infected whole blood 2 weeks after the last immunization. Mice in the infection control group were intraperitoneally injected with 100 μL of B. microti-infected whole blood, while 15 mice in the normal control group received no treatment. Blood samples were collected from mice in the recombinant protein immunization group and the infection control group on days 0 to 30 post-immunization for detection of B. microti infection, and blood samples were collected on days 0, 7, 14, 21, and 28 post-immunization for routine blood tests with a blood cell analyzer and for detection of serum cytokines using cytometric bead array. Results Anti-BmPPIase antibodies were detected in 25 mice in the recombinant protein immunization group 2 weeks after the last immunization, with titers of 5 × 103 to 8 × 104. B. microti infection rate peaked in mice in both the recombinant protein immunization and the infection control group on day 7 post-immunization, with positive infection rates of 13.3% and 50.0%, and there were significant differences between the two groups in terms of B. microti infection rate on days 3 (χ2= 113.18, P < 0.01), 5 (χ2 = 475.22, P < 0.01), 7 (χ2 = 465.98, P < 0.01) and 9 post-infection (χ2= 18.71, P < 0.01), while the B. microti infection rate tended to be 0 in both groups on day 11 post-immunization. Routine blood tests showed higher red blood cell counts [(5.30 ± 0.50) × 1012 to (9.87 ± 0.24) × 1012 counts/L)] and hemoglobin levels [(89.67 ± 22.80) to (148.60 ± 3.05) g/L)] in the recombinant protein immunization group than in the infection control group on days 0 to 28 post-immunization. Cytometric bead array detected higher serum interferon-γ [(748.59 ± 17.56) to (3 858.28 ± 1 049.10) fg/mL], tumor necrosis factor-α [(6 687.34 ± 1 016.64) to (12 708.13 ± 1 629.79) fg/mL], interleukin (IL)-6 [(611.05 ± 75.60) to (6 852.68 ± 1 554.00) fg/mL] and IL-17a [(167.68 ± 185.00) to (10 849.27 ± 355.40) fg/mL] and lower IL-10 levels [(247.65 ± 138.00) to (18 787.20 ± 2 830.22) fg/mL] in the recombinant protein immunization group than in the infection control group during the study period. Conclusions Recombinant BmPPIase protein induces up-regulation of interferon-γ, tumor necrosis factor-α and presents a high immunoprotective activity against B. microti infection in mice, which is a potential vaccine candidate protein.

ABSTRACT

Aim To compare the effects of different time sequence interventions on virus infected mice by using oseltamivir (Tamiflu) as a "tool drug" in view of the current situation of the too early the administration time of antiviral in vivo experiment, so as to provide a basis for selecting a reasonable model intervention time point for antiviral drug research. Methods Balb/c mice were randomly divided into six groups. The virus infection model was established by intranasal infection with influenza virus (0.25 TCID50). Tamiflu-1 group and Tamiflu-2 group were administered orally on 1st and 4th day after exposure. The body mass, survival rate, organ index, viral load and inflammatory factor content were measured. Results Compared with the blank control group, the body weight of the mice in the model group decreased and the lung index increased significantly (P < 0.05). The expression levels of 13 inflammatory factors in model 2 group were significantly different ( P < 0.05). Compared with the model-1 group ,the lung index and spleen index of the Tamiflu-1 group decreased significantly (P < 0.05). Compared with the mode-2 group,the lung index in the Tamiflu-2 group was significantly lower (P <0.05) ,and the thy-mus index was significantly higher (P<0.05). The viral load was 0. 03 times that of the model-2 group. The expression levels of 13 inflammatory factors were significantly different (P < 0. 05). Conclusions The symptoms of the mice in Scheme 2 are more obvious and stable after exposure. After administration, the lung inflammation damage is alleviated. Considering the latency, drug intervention is in line with the drug indications when the model animals show symptoms. It will be more reasonable and accurate whether in the model evaluation or drug evaluation.
