Abstract
Objective: To explore the feasibility of endoscopic lymph node dissection(LND) with programmed breast approach for the treatment of papillary thyroid cancer. Methods: A case series study. The clinical data of 39 patients with papillary thyroid cancer who underwent endoscopic LND treatment with programmed breast approach in Shenzhen People's Hospital from January to November 2022 were retrospectively analyzed. There were 10 males and 29 females, aged (35.95±10.17) years. LND time, total surgical time, intraoperative bleeding volume, postoperative drainage volume, postoperative hospital stay and postoperative complications were analyzed. Results: Among 39 patients, there were 18 cases of unilateral thyroid cancer, 21 cases of bilateral thyroid cancer, 35 cases of unilateral LND, and 4 cases of bilateral LND. The maximum diameter of thyroid cancer lesions was (1.48±0.69) cm, and the maximum diameter of lymph node metastases was (1.63±0.58)cm. The operative time of unilateral neck dissection was (124.11±19.92) min (102-170 min), and the total operative time was (226.42±55.68) min (110-390 min). The number of lymph nodes cleaned was (32.40±10.44)(12-54), the number of metastasis and detection was 207/1 393. The postoperative drainage volume was (174.64±82.33) ml(41-350 ml). There were no neck hematomas, no skin burns or no shrugging disorders in the postoperative period. There were 7 cases of numbness and discomfort in neck skin sensation, which gradually relieved after half a year. Postoperative discharge time (4.77±1.94) d(3-15 d). Conclusion: It is safe and feasible to treat papillary thyroid cancer with endoscopic LND with programmed breast approach, which can improve surgical efficiency and clinical application value.

Abstract
OBJECTIVE To investigate the protective effect of Echinococcus granulosus hydatid cyst fluid protein (HCFP) on ovalbumin (OVA)-induced allergic rhinitis (AR) in mice. METHODS Twenty-four BALB/c mice at ages of 8 to 10 weeks, each weighing approximately 20 g, were randomly divided into four groups, including groups A (blank control group), B (blank intervention group), C (AR model group) and D (AR+HCFP intervention group), with 6 mice in each group. On days 0, 2, 4, 6, 8, 10 and 12, mice in groups A, B, C and D were injected with 200 μL sterile phosphate buffered saline (PBS), 200 μL sterile PBS containing 20 μg HCFP, 200 μL sterile PBS containing 50 μg OVA and 5 mg Al(OH)3 gel, and 200 μL sterile PBS containing 50 μg OVA, 5 mg Al(OH)3 gel and 20 μg HCFP, respectively. On days 14 to 20, mice in groups A, B, C and D were administered with 40 μL sterile PBS, 40 μL sterile PBS containing 20 μg HCFP, 40 μL sterile PBS containing 2 mg OVA and 40 μL sterile PBS containing 2 mg OVA and 20 μL HCFP by nasal drop, respectively. Mouse behavioral changes were observed and behavioral scores were estimated. The serum levels of interferon-γ (IFN-γ), interleukin-4 (IL-4), IL-5, IL-10, transforming growth factor-β (TGF-β) and OVA-specific IgE antibody (OVA-sIgE) were measured using enzyme-linked immunosorbent assay (ELISA), and the pathological changes of mouse nasal mucosa were observed by hematoxylin and eosin (HE) staining. RESULTS The mean behavioral score was significantly greater in Group C (6.83 ± 0.50) than in groups A (1.17 ± 0.52) and B (1.33 ± 0.52) (P < 0.05), while a lower mean behavioral score was estimated in Group D (3.50 ± 0.50) than in Group C (P < 0.05). There were significant differences among the groups in terms of serum IFN-γ (F = 4.08, P < 0.05), IL-4 (F = 275.90, P < 0.05), IL-5 (F = 96.82, P < 0.05), IL-10 (F = 77.67, P < 0.05), TGF-β (F = 9.98, P < 0.05) and OVA-sIgE levels (F = 44.69, P < 0.05). The serum IFN-γ level was significantly lower in Group C than in groups A, B and C (P < 0.05), and the serum levels of IL-4, IL-5 and OVA-sIgE were significantly higher in Group C than in groups A, B and C (P < 0.05), while the serum IL-10 and TGF-β levels were significantly greater in Group D than in Group C (P < 0.05). Microscopy showed apparent loss of nasal mucosa cilia, increased number and enlargement of goblet cells, interstitial edema and submucous vascular dilation in Group C, while the pathological changes of nasal mucosa were alleviated in Group D relative to Group C. CONCLUSIONS E. granulosus HCFP has a protective activity against OVA-induced allergic rhinitis in mice.

Abstract
OBJECTIVE To analyze the components of proteins from Echinococcus granulosus cyst fluid using the shotgun method, and to identify the active components with potential regulatory effects for immune dysregulation diseases. METHODS The E. granulosus cyst fluid was collected aseptically from the hepatic cysts of patients with cystic echinococcosis, and characterized by liquid chromatography (LC) tandem mass spectrometry (MS/MS) following digestion with trypsin. The protein data were searched using the software MaxQuant version 1.6.1.0 and the cellular components, molecular functions, and biological processes of the identified proteins were analyzed using the Gene Ontology (GO) method. RESULTS The E. granulosus cyst fluid separated by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) had a relative molecular mass of 25 to 70 kDa. LS-MS/MS analysis identified 37 proteins, including 32 known proteins and 5 unknown proteins. At least 4 proteins were preliminarily found to exhibit potential regulatory effects for immune dysregulation diseases, including antigen B, glutathione-S-transferase (GST), thioredoxin peroxidase (TPX) and malate dehydrogenase (MDH). GO enrichment analysis showed that the identified proteins had 149 molecular functions and were involved in 341 biological processes. CONCLUSIONS E. granulosus cyst fluid has a variety of protein components, and four known proteins are preliminarily identified to be associated with immune dysregulation diseases.

Abstract
Trichinellosis is a worldwide zoonotic parasitic disease, which may infect humans and a wide range of animals, including carnivores, herbivores and even birds. Humans get infections through ingestion of raw or semi-cooked meat or meat products containing live Trichinella larvae. Currently, this zoonosis is predominantly prevalent in southwestern, northeastern and central parts of China, which poses a great threat to human health and socioeconomic development. In addition, the emergent public health hazards caused by trichinellosis outbreaks greatly threaten human health and social stability. This review describes the current status, diagnosis, treatment and control measures of trichinellosis in China, so as to provide insights into trichinellosis control in the country.

Abstract
Objective: To investigate the systemic expression profile of S100A8 and S100A9 in healthy and inflamed periodontal tissues. Methods: Experimental periodontitis models were established by ligations around the mandibular second molars of six beagle dogs for 12 weeks (ligation group). The mandibular second molars on the opposite side were kept clean (healthy control group). The expressions of S100A8 and S100A9 in healthy and inflamed periodontal tissues of six beagle dogs were examined by immunohistochemistry. The expressions of S100A8 and S100A9 in primary human gingival fibroblasts (hGF) from 3 subjects and human periodontal ligament cells (hPDLC) from 3 other subjects were detected by immunocytochemistry. Results: After the ligation for 12 weeks, the mean probing depth of ligation group [(3.86±0.14) mm] was significantly higher than that of healthy control group [(2.11±0.28) mm] (P<0.01). Results of immunohistochemistry analysis indicated that S100A8 and S100A9 could be expressed in gingival epithelial cells and might infiltrated neutrophils in the healthy periodontium. Except for the gingival epithelial cells and neutrophils, both proteins were induced and expressed in gingival fibroblasts, periodontal ligament cells, microvascular endothelial cells and bone marrow fibroblasts under inflammatory conditions. The distribution of S100A8 and S100A9 differed in the healthy oral gingival epithelium (OGE), which becomes consistent in inflamed OGE. Additionally, the expressions of S100A8 and S100A9 were confirmed in primary hGF and hPDLC. Conclusions: Periodontal inflammation might enlarge the expression scope of S100A8 and S100A9 and enrich multiple cells with expressions of S100A8 and S100A9.

Abstract
This study aimed to explore the risk factors for severity of white matter lesions and its correlation with in the elderly with lacunar infarction.Patients (range, 70-85 years) with lacunar infarction treated in a hospital in China from 2016 to 2017were enrolled. Fazekas rating scale (0-6 points) was used to assess severity of white matter lesions. Risk factors for the severity of white matter lesions and correlation between cerebral microbleeds and white matter lesions in the elderly with lacunar infarction were studied.The elderly (81-85 years' old, odds ratio [OR]: 2.423, 95% confidence interval [CI]: 1.795-3.271, P = .018; 76∼80 years' old, OR: 3.113, 95% CI: 1.723-5.625, P = .043), carotid atherosclerosis (OR: 3.062, 95% CI:1.715-5.468, P < .001), history of hypertension (OR: 3.694, 95% CI: 2.031-6.717, P < .001) were risk factors for the severity of white matter lesions. The white matter lesions score increased corresponding to increase in the cerebral microbleeds grade (P < .001). The white matter lesions score was higher in the cerebral microbleeds combined with the white matter lesions group than in the white matter lesions group (P < .01). After correcting the effects of age, there was a correlation between white matter lesions and cerebral microbleeds (P < .001). Logistic analysis revealed that the patients' age (81-85 years' old, OR: 2.722, 95% CI: 1.985-3.734, P = .019; 76∼80 years' old, OR: 1.857, 95% CI: 1.075-3.207, P = .031), history of hypertension (OR: 2.931, 95% CI: 1.136-7.567, P = 0.0.036), systolic blood pressure (OR: 1.049, 95% CI: 1.015-1.084, P = .007), high-sensitivity C-reactive protein (OR: 1.504, 95% CI: 1.254-1.803, P < .001), homocysteine (OR: 1.076, 95% CI: 1.020-1.136, P = .009), and carotid atherosclerosis (OR: 1.389, 95% CI: 1.103-1.748, P = .010) were significant risk factors for combined cerebral microbleeds with white matter lesions in patients with lacunar infarction.The elderly, carotid atherosclerosis, history of hypertension were risk factors for the severity of white matter lesions. Cerebral microbleeds were positively correlated with the severity of white matter lesions.

Abstract
Objective: To study the changes of gonadotropin releasing hormone agonist (GnRH-a) in pinopodes during luteal phase and to explore the possible mechanism of GnRH-a in luteal phase support of assisted reproductive technology (ART). Methods: Totally 40 primary infertility women who were treated with ART due to male factors were enrolled, according to the order of the group they were randomly divided into experimental group and control group. On the 7th day after ovulation, the experimental group received a subcutaneous injection of 0.1 mg of GnRH-a, while the control group received a subcutaneous injection of placebo only (0.9% saline 2 ml), 3 days later they came to the clinic again. Serum estradiol and progesterone levels were measured before and after treatment in each group. Pinopodes were collected for electron microscopic examination. Levels of ER and PR were detected by western blot. Results: (1) There was no significant difference between the experimental group and the control group in the estrogen level before and after the treatment (all P>0.05). The level of progesterone in the experimental group after treatment [(66.8±14.9) nmol/L] was significantly higher than that before treatment(P<0.05); also significantly higher than the same period of the control group (P<0.05). (2) There was no significant difference in the expression of ER protein in the experimental group before and after treatment (P>0.05). The expression of PR in the experimental group after treatment was significantly lower than that before treatment (P<0.05); also lower than the same period of the control group (P<0.05). (3) Expression amount of pinopodes in the experimental group after treatment was significantly higher than that before treatment [65% (13/20) versus 25% (5/20), P<0.05], and the development trend was more mature [the percentage of maturation:75% (15/20) versus 35% (7/20), P<0.05]. Expression amount of pinopodes after treatment and the percentage of maturation in the experimental group were significantly higher than those in the same period of control group (P<0.05). Conclusion: GnRH-a in luteal phase support may play a role through the corpus luteum, which may promote the secretion of progesterone, downregulation of PR expression, promote the growth of pinopodes, and improve the endometrial receptivity.

Abstract
Diabetic peripheral neuropathy (DPN), a common complication of diabetes, has a high morbidity, and currently there is no effective therapy. To investigate the clinical effect of traditional Chinese medicine in combination with Western medicine, 88 patients with early DPN who were admitted to Binzhou City Center Hospital, Shandong, China, between November 2015 and November 2016, were selected as the research subjects and were randomly divided into a control group and an observation. Patients in the control group were treated by conventional Western medicine, while patients in the observation group were treated by traditional Chinese medicine in addition to conventional Western medicine. The clinical effect was compared between the two groups. The results demonstrated that the overall effective rate of the observation group was much higher than that of the control group, and the difference was statistically significant (P less than 0.05). The vibration perception threshold (VPT) of nervus peroneus communis, nervus suralis and posterior tibial nerve of the two groups significantly declined after treatment (P less than 0.05), however, the decreae in the observation group was more obvious (P less than 0.05). The improvement of glycosylated hemoglobin (HbAlc) and blood glucose of the observation group was superior to that of the control group, and the difference had statistical significance (P less than 0.05). In conclusion, traditional Chinese medicine in combination with Western medicine has a remarkable effect in the treatment of DPN and can effectively relieve vital signs and clinical symptoms of patients and significantly improve nerve conduction velocity. The therapy is worth clinical application and promotion.

Abstract
PURPOSE This study aimed to investigate the correlation between cerebral microbleeds and carotid atherosclerosis in patients with ischemic stroke. SUBJECTS AND METHODS Patients with ischemic stroke treated in a hospital in China from 2016 to 2017 were enrolled in the study. Based on the results from susceptibility-weighted imaging, the patients were divided into cerebral microbleed and noncerebral microbleed groups. The degree of carotid atherosclerosis was assessed with carotid intima-media thickness (CIMB) and Crouse score of carotid plaque. The details of patients' demographic information, cerebrovascular disease-related risk factors, carotid atherosclerosis indices, cerebral microbleed distribution, and grading were recorded, compared, and analyzed. RESULTS Logistic regression analysis of the 198 patients showed that CIMB and Crouse score were significantly correlated with the occurrence of cerebral microbleeds. The CIMB thickening group (P = .03) and the plaque group (P = .01) were more susceptible to cerebral microbleeds. In the distribution of cerebral microbleed sites, Crouse scores were the highest in the mixed group and showed a statistically significant difference (P < .01). As the degree of carotid atherosclerosis increased, the average number of cerebral microbleeds also increased (P < .01). The receiver operating characteristic curve analysis of the carotid atherosclerosis indices showed a statistically significant difference. The CIMB value combined with the Crouse score was the best indicator (P < .01). CONCLUSION In patients with ischemic stroke, cerebral microbleeds are closely related to carotid atherosclerosis. Active control of carotid atherosclerosis is important to prevent cerebral microbleeds in patients with ischemic stroke.

Abstract
Two combination chemotherapy protocols, CMF (cyclophosphamide, methotrexate, fluorouracil) and CMFH (CMF plus homoharringtonine), were tested in advanced breast cancer patients. The response rate of CMF was 50% in 44 cases, and that of CMFH was 54.16% in 48 cases; the difference was not significant. There was also no difference between the median duration of response and the median survival of the two protocols. It was concluded that the addition of homoharringtonine to the CMF protocol gave no additional benefit.

Abstract
We evaluated the application of three machine learning algorithms, including logistic regression, support vector machine and back-propagation neural network, for diagnosing congenital heart disease and colorectal cancer. By inspecting related serum tumor marker levels in colorectal cancer patients and healthy subjects, early diagnosis models for colorectal cancer were built using three machine learning algorithms to assess their corresponding diagnostic values. Except for serum alpha-fetoprotein, the levels of 11 other serum markers of patients in the colorectal cancer group were higher than those in the benign colorectal cancer group (P < 0.05). The results of logistic regression analysis indicted that individual detection of serum carcinoembryonic antigens, CA199, CA242, CA125, and CA153 and their combined detection was effective for diagnosing colorectal cancer. Combined detection had a better diagnostic effect with a sensitivity of 94.2% and specificity of 97.7%; combining serum carcinoembryonic antigens, CA199, CA242, CA125, and CA153, with the support vector machine diagnosis model and back-propagation, a neural network diagnosis model was built with diagnostic accuracies of 82 and 75%, sensitivities of 85 and 80%, and specificities of 80 and 70%, respectively. Colorectal cancer diagnosis models based on the three machine learning algorithms showed high diagnostic value and can help obtain evidence for the early diagnosis of colorectal cancer.

Abstract
BACKGROUND CA19-9, CA125, AFP, CEA, and CA153 are common cancer biomarkers. This study aimed to detect the expression and assess clinical significance of these biomarkers in ovarian mature cystic teratomas (OMCT). MATERIALS AND METHODS The clinical data of 312 resected patients with ovarian mature cystic teratoma referred to the third Hospital of Suzhou University from January 2008 to February 2014 were analyzed retrospectively. Levels of serum CA19-9, CA125, CA153, AFP, and CEA were detected. RESULTS Levels of serum CA19-9, CA125, AFP, and CEA were detected in all patients, but the level of serum CA153 was detected in 36 patients. The positive expression of these biomarkers above is 45.83%, 6.09%, 0.00%, 0.64%, and 2.78%, respectively. Ovarian tumor diameter in CA19-9 and CA 125 elevation is larger than that in negative group. The levels of serum CA19-9 and CA125 in multilocular ovarian tumor patients is higher than that in unilocular ovarian tumor patients. The level of serum CA19-9 in bilateral ovarian tumor patients is higher than that in unilateral patients. The level of CA19-9 in patients three months after operation decreased significantly compared with that before operation. CONCLUSIONS The present study suggests that elevated CA 19-9 is probably the most reliable marker among many tumor markers in the OMCT. It is valuable for diagnosis and recurrence of OMCT.

Abstract
Gossypium tomentosum is a wild allotetraploid species with the (AD)5 genome. It is characterized by many useful traits including finer fiber fineness, drought tolerance, and Fusarium and Verticillium resistance. We constructed the first bacterial artificial chromosome library for Gossypium tomentosum. With high quality and broad coverage, this library includes 200,832 clones, with an average insert size of about 122 kb and fewer than 3% empty clones. Our library is approximately 10-fold the size of the (AD)5-genome (2400 Mb) and provides a 99.7% probability of isolating genes of interest or their sequences. Seven of eight simple sequence repeats markers that are located on five different chromosomes and linked with resistance to Verticillium wilt could amplify the 50 superpools and obtained one to five hits. This high capacity library will be an important genomic resource for classifying and analyzing the evolution of allotetraploid cotton species as well as for isolating disease-resistance and drought-tolerance genes.

Immunomodulatory and clinical effects of the "tiaomian III decoction" in patients with blood blocking antibody deficiency and recurrent spontaneous abortion.

Abstract
We studied the immunomodulatory and clinical effects of the empirical formula "tiaomian III decoction" on maternal blood blocking antibody deficiency and recurrent spontaneous abortion. Sixty-one patients with blocking antibody deficiency were divided in the experimental group (N = 31), who took tiaomian III decoction, and the control group (N = 30), who received active immunotherapy with paternal lymphocytes; both treatments lasted 3 months. Blocking antibodies, anti-idiotypic antibodies, interleukin, T-lymphocyte subsets, and macrophage colony-stimulating factor (M-CSF) were tested. After treatment, the positive conversion rate reached 87.1 and 86.7% in the experimental and control groups, respectively. After treatment, CD4 levels decreased while CD8 levels increased in both groups. The CD4/CD8 ratio was higher than normal and increased significantly from pre-treatment (P < 0.05). IL-10 and M-CSF levels increased significantly in both groups (P < 0.05). The 1-year conception rates of the experimental and control groups were 58.1 and 46.7%, respectively (P < 0.05). The results show the tiaomian III decoction can increase the positive conversion rate of maternal blocking antibodies and promote the production of IL-10 and M-CSF. Thus, it strengthens the maternal body's protection of the fetus and maintenance of conception. The higher conception rate of the experimental group demonstrates the positive clinic efficacy of the tiaomian III decoction on maternal blood blocking antibody deficiency and recurrent spontaneous abortion.

Fabrication of silver tips for scanning tunneling microscope induced luminescence. THE REVIEW OF SCIENTIFIC INSTRUMENTS 2011; 82:083101.

Abstract
We describe a reliable fabrication procedure of silver tips for scanning tunneling microscope (STM) induced luminescence experiments. The tip was first etched electrochemically to yield a sharp cone shape using selected electrolyte solutions and then sputter cleaned in ultrahigh vacuum to remove surface oxidation. The tip status, in particular the tip induced plasmon mode and its emission intensity, can be further tuned through field emission and voltage pulse. The quality of silver tips thus fabricated not only offers atomically resolved STM imaging, but more importantly, also allows us to perform challenging "color" photon mapping with emission spectra taken at each pixel simultaneously during the STM scan under relatively small tunnel currents and relatively short exposure time.

Preliminary observations on the antifatigue effects of longan (Dimocarpus longan Lour.) seed polysaccharides. Phytother Res 2010; 24:622-4.

Abstract
The antifatigue effects of the hot-water extract of longan (Dimocarpus longan Lour.) seeds were studied in mice. Longan seed polysaccharides were administered at doses of 50, 100, 200 and 400 mg/kg and antifatigue activity was evaluated using a swimming test, along with the determination of serum urea nitrogen, hepatic glycogen and blood lactic acid content. The results show that longan seed polysaccharides, in doses ranging from 50 to 100 mg/kg, extended swimming time, increased hepatic glycogen (p < 0.01, n = 10), reduced blood urea nitrogen (p < 0.01, n = 10) and decreased blood lactic acid (p < 0.01, n = 10) in the mice. Therefore longan seed polysaccharides may have potential as an antifatigue agent.

Topical formulations of fluocinolone acetonide. Are creams, gels and ointments bioequivalent and does dilution affect activity? Eur J Clin Pharmacol 1994; 46:71-5.

Abstract
The study was done in healthy volunteers to investigate the vasoconstrictor activity of three commercially available formulations of fluocinolone acetonide (Synalar gel, cream and ointment) and to determine whether they were bioequivalent. The influence of dilution of the cream formulation on activity was also examined. Twenty mg of each topical formulation was applied, followed by occlusion for 6 h, and the potency was evaluated by measuring the vasoconstrictor effect using tristimulus colour analysis. The cream formulation was more potent than the ointment, with the gel having intermediate strength. Dilution did not significantly reduce activity. While choice of an appropriate topical corticosteroid formulation largely depends on the nature of the lesions, this study has shown that different formulations of nominally the same concentration have different potencies; dilution up to 1 in 10 produced no significant reduction in potency. The potency classification in the British National Formulary for formulations of Synalar may need revision.

Abstract
Oligodeoxynucleotides (Oligomers) including modified and unmodified, homo- and heterooligomers were tested for their ability to inhibit mouse SRS leukemia virus (SRSV)-induced proliferation of cells, colony formation, syncytium formation and reverse transcriptase (RT) activity in vitro. Phosphorothioate analogs complementary to Mo-MuLV sequences, as well as noncomplementary homooligomers, were found to be active. Unmodified homooligomer (dC14) also showed inhibition of growth of ascitic lymphoma carrying SRS virus. Our study suggests that different classes of oligonucleotides may inhibit SRSV replication with different mechanisms.
