Long-term indwelling gastric tube for prevention and treatment of esophageal stricture after endoscopic submucosal dissection for esophageal circumferential superficial cancer / 中华消化内镜杂志

To investigate the effect of long-term indwelling gastric tube on the prevention and treatment of esophageal stenosis after endoscopic submucosal dissection (ESD) for esophageal circumferential superficial cancer, data of patients with esophageal circumferential superficial cancer who underwent ESD in the First Affiliated Hospital of Nanjing Medical University from January 2018 to December 2021 were retrospectively analyzed. There were 15 patients with gastric tube placement (GTP) after ESD (the GTP group ), and 23 patients without GTP (the non-GTP group). The general information, lesion location, pathological stage, postoperative complications, degree of esophageal stenosis (water intake), pain conditions, number of hospitalizations and medical expenses were compared between the two groups. The results showed that there was no significant difference in age, gender, lesion location or postoperative pathological stage between the two groups ( P>0.05). Compared with the non-GTP group, the rate of water intake in the GTP group was significantly higher (11/15 VS 6/23, P<0.05), the frequency of pain was less in the GTP group (7.3±3.1 times VS 10.7±3.6 times, t=3.00, P<0.05), and the number of hospitalizations and the medical expenses after ESD to before and after stent placement were significantly lower in the GTP group than those in the non-GTP group ( P<0.05). There were no significant differences in the incidence of delayed bleeding and perforation, or time of the first stenosis after ESD between the two groups ( P>0.05). The results of the study initially showed that long-term indwelling gastric tube after ESD can reduce the degree of esophageal stenosis with good safety for esophageal circumferential superficial lesions.

Human leukocyte antigen analysis in a case of autoimmune polyendocrine syndrome type Ⅲ and complicated with myasthenia gravis / 中华内分泌代谢杂志

Type 1 diabetes mellitus and autoimmune thyroid disorders are the most common combination of autoimmune polyendocrine syndrome type Ⅲ(APS Ⅲ). However, APS Ⅲ combined with myasthenia gravis is rare. We described a male patient with myasthenia gravis, type 1 diabetes mellitus, and Hashimoto thyroiditis, who was diagnosed as APS Ⅲ. The human leukocyte antigen (HLA)type was analyzed in this patient. We subsequently reviewed 11 cases of APS Ⅲ combined with myasthenia gravis. This review revealed that HLA-DR9/DQ9 might be a specific HLA subtype associated with APS Ⅲ and complicated with myasthenia gravis .

Clinical Efficacy of Ditantang on Pediatric Epilepsy with Phlegm and Stasis-type Tonic-clonic Seizure and Its Effect on Immunoglobulin, Peripheral Blood Th17 Cells and Relevant Factors / 中国实验方剂学杂志

Objective:To observe the clinical efficacy of Ditantang on phlegm turbid-blocked obstruction type tetan-burst twins in children with epilepsy and its effect on immunoglobulin, Peripheral blood helper T cells 17（Th17）， interleukin-6 (IL-6) and interleukin-17A（IL-17A）in children with epilepsy. Method:The random distribution sequences of 100 children generated by the random number table method were placed in sealed envelopes, and the subjects were divided into the corresponding experimental group and treatment group. Control group was treated with sodium valproate oral solution, and treatment group was also treated with Ditantang in addition to the therapy of control group. The total course of treatment was 3 months. The changes of immunoglobulin M（IgM）， immunoglobulin A（IgA），immunoglobulin G（IgG）, peripheral blood Th17 cells，IL-6，IL-17A, C-reactive protein (hs-CRP), blood homocysteine (Hcy) and the adverse reactions were detected before and after treatment in two groups. The changes in the number of seizures, duration of seizures and EEG before treatment and 3 months after treatment were compared between the two groups. Result:Three months after the treatment of phlegm-blocking obstruction type tetan-burst twin epilepsy with Ditantang combined with sodium valproate, the results showed that the total effective rate of treatment group was superior to that of control group, with statistically significant differences (P<0.05). After treatment, treatment group was superior to control group in the reduction of epilepsy score (P<0.05). Compared with before treatment, the levels of IgG，IgA and IgM in treatment group were significantly increased (P<0.05), while the levels of Th17，IL-6，IL-17A，hs-CRP and Hcy in peripheral blood were significantly decreased. Compared with control group, the levels of Th17，IL-6，IL-17A，hs-CRP and Hcy in peripheral blood decreased significantly after treatment (P<0.05). The incidence of adverse reactions in control group was significantly higher than that in treatment group (P<0.05). Conclusion:Ditantang is effective and safe in treating phlegm turbidness and obstruction type epilepsy (tetan-episode twin), and can improve the clinical symptoms of children and electroencephalogram. Besides, it can improve the level of immunoglobulin in children, significantly reduce the levels of Th17，IL-6 and IL-17A in their peripheral blood, regulate the immune function of the body, and reduce the incidence of adverse reactions.

Two cases of autoimmune polyendocrine syndrome type Ⅰ caused by AIRE gene mutation / 中华内分泌代谢杂志

Objective@#Autoimmune polyendocrine syndrome type Ⅰ(APS-Ⅰ) is caused by mutations in the autoimmune regulator gene (AIRE) gene. In this study, phenotype and AIRE gene analysis were performed in two patients with APS-Ⅰ.@*Methods@#Peripheral blood samples were collected from two patients with APS-Ⅰ and their families. All exons of the AIRE gene and adjacent exon-intron sequences were amplified by PCR and subsequently sequenced. The silico analysis was performed to predict the possible impact of the mutations on the function of the AIRE protein. At the same time, 100 healthy controls were selected to confirm the mutation.@*Results@#Case 1 was a 31-year-old female who exhibited chronic mucocutaneous candidiasis, hypoparathyroidism, Addison′s disease, Hashimoto′s thyroiditis, and premature ovarian failure. A homozygous c. 483_484insC mutation in exon 4 of AIRE gene was identified in this patient. Her parents, siblings and son were heterozygous for this mutation, which is consistent with the autosomal recessive inheritance pattern. Case 2 was a 34-year-old male who had mucocutaneous candidiasis, Addison′s disease, primary hypoparathyroidism, and Hashimoto′s thyroiditis. A compound heterozygous AIRE mutation (c.179A>G/C.463+ 2T>C) were identified in this patient. His father was heterozygous for c. 179A>G mutation, and his mother was heterozygous for C. 463+ 2T>C, which is consistent with autosomal recessive inheritance mode. The c. 483_484insC and c. 463+ 2T>C have been reported to be pathogenic. The c. 179A>G mutation was predicted pathogenic by SIFT and PolyPhen2 software, which was not detected in 100 healthy controls. It has not been reported in the HGDM database and is a novel mutation.@*Conclusion@#We identified a novel AIRE gene mutation (c.179A>G), which contributed to further understanding of the pathogenesis of APS-Ⅰ. The clinical variation and rarity of APS-Ⅰ makes the syndrome hard to recognize. Early recognition of symptoms and screening for AIRE mutation in patients with APS-Ⅰ has important clinical implications for the diagnosis and treatment.

The Experimental Study of Cyasterone on the Treatment of Osteoporosis through the Bidirectional Effect of Inhibiting Osteoclast Differetiation and Promoting Osteoblast Differentiation / 昆明医科大学学报

Objective To explore the influence of cyasterone on the osteoclast and osteoblast differentiation and then to investigate its effect on the bone quality in the osteoporosis mice. Methods CCK8 assay was firstly used to detect the toxic effect of cyasterone on the mouse bone marrow derived mononuclear macrophages (BMMs) and anterior osteoblast lines MC3T3E1. Cell apoptosis was measured by flow cytometry. Then TRAP staining and ALP staining were employed to detect osteoclast differentiation and osteoblast differentiation, respectively. Realtime PCR was carried out to test the expression of osteoclast special gene TRAP and osteogenesis crucial gene ALP. In vivo, 15 mice were divided into three groups: sham-operated group, OVX group and OVX+cyasterone treatment group. In treatment group, cyasterone was used as 5mg/kg every day. Sham-operated group and OVX group were treat with saline solution. After 4 weeks, the tibia was collected for Micro-CT detection to observe the bone quality and microstructure changes. Results Cyasterone with the concentration of less than 10 mg/L had no significant cytotoxicity nor influence on the apoptosis (P＞0.05) . Cyasterone could significantly inhibit the osteoclast differentiation of BMMs (P＜0.05), simultaneously, it also had the effect to promote the osteoblast differetiation of MC3T3E1. Real-time PCR indicated that cyasterone could block the expression of TRAP and increase the expression of ALP (P＜0.05) . In vivo, cyasterone was able to obviously improve the osteoporosis status caused by estrogen deficiency without general toxicity. Conclusion cyasterone could provide a good treatment for osteoporosis through the bidirectional effect of inhibiting osteoclast differetiation and promoting osteoblast differentiation.

Clinical and pathological features in children with progressive muscular dystrophy / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To investigate the clinical and pathological features of progressive muscular dystrophy (PMD) in children and to provide help for the early and accurate diagnosis of PMD.</p><p><b>METHODS</b>Retrospective analysis was performed on the clinical data of 99 hospitalized children with PMD, including clinical manifestations, age of onset, family history, creatase, electromyogram (EMG) and pathological changes of muscles.</p><p><b>RESULTS</b>Of the 99 children with PMD, the age of onset was 0.5-14.5 (4.7 ± 3.1) years. Eleven cases (11%) had a family history of PMD. Twenty-six (26%) were misdiagnosed as other diseases. All patients presented with muscle weakness when seeing the doctor, and 66 (67%) of them had muscle atrophy and/or hypertrophy. All patients had elevated creatine kinase (CK) levels. The 2-7-year-old group (n=51) had a mean CK level of 9965 ± 8876 U/L, and the 7-15-year-old group (n=48) had a mean CK level of 5110 ± 4498 U/L, with a significant difference between the two groups (P<0.01). The EMG examination performed on 66 patients showed that 54 cases (82%) had myogenic damage and 10 cases (15%) had neurogenic damage. Light microscopy revealed coexistence of atrophy and hypertrophy of muscle fibers, hyaline degeneration and granular degeneration. Electron microscopy showed that muscle fibers were different in thickness, some atrophic or hypertrophic; muscle cell nuclei moved inwardly, myofilaments dissolved and disappeared mildly under the sarcolemma, there were scattered melting lesions within muscle fibers, the numbers of glycogen granules and mitochondria increased, mild hyperplasia and expansion of sarcoplasmic reticulum were seen, and a small number of muscle fibers had necrosis.</p><p><b>CONCLUSIONS</b>Weakness of both lower extremities remains the main reason for PMD patients seeing the doctor. CK is the main laboratory indicator for diagnosis of PMD. PMD is mainly manifested as myogenic damage in the early stage and may be accompanied by neurogenic damage in the late stage, according to the EMG examination. With a high misdiagnosis rate, PMD may be misdiagnosed as many other diseases. Pathological examination under light microscope and electron microscope is the main means for confirming a PMD diagnosis.</p>

BackgroundDry eye is a multi-factorial-induced tear film and ocular surface disorder.Immunoinflammation plays a key role in the pathogenesis of dry eye.As inhibitor of the cyclo-oxygenase pathway,nonsteroidal anti-inflammatory drugs play an anti-inflammatory and anti-hypersensitivity role,and it can be a potential treatment for dry eyes.ObjectiveThis study was to investigate the effectiveness of nonsteroidal anti-inflammatory drugs (0.1％topical pranoprofen) on moderate to severe dry eyes and its mechanism.MethodsThis was a small sample of randomized controlled clinical trial.Thirty right eyes of 30 patients with moderate to severe dry eyes were included in the study according to the diagnosis criteria and randomized into two groups.The patients of the trial group received topical administration of 0.1％ pranoprofen plus 0.1％ sodium hyaluronate,and those of the control group received the topical 0.1％ sodium hyaluronate only.Ocular surface inflammation index scores (OSDI) and ocular surface fluorescine staining (OSS) scores were measured under the slit lamp,and tear film break-up time (BUT),Schirmer Ⅰ test values were evaluated.The expression of human leucocyte antigen-DR (HLA-DR) and CD11b in conjunctiva epithelial cells were detected by impression cytology and flow cytometry (FCM).All the indexes were compared between the two groups before and after treatment.Informed consent was obtained from all patients.ResultsThere were no significant differences in terms of age and gender and their baseline values between the trial group and control group (t=0.412,P=0.684;x2=0.240,P=0.624),and so were all the indexes (P＞0.05).Compared with the control group,the OSDI,OSS scores and cells positive for HLA-DR were lowered but the BUT was delayed in the trial group on day 15 ( t=2.43,P=0.03;t=2.83,P=0.01;t=3.29,P=0.00;t=3.23,P=0.00 ).No significant differences were found in the Schirmer Ⅰ test value and CD11b expression between these two groups (t=0.17,P=0.87;t=0.28,P=0.79).The OSDI,OSS scores and BUT were significantly improved,and the number of cells positive for HLA-DR were reduced 15 days after administration of drugs in comparison with before treatment in the trial group ( t =12.30,10.70,6.10,7.92,P =0.00 ).However,there were no comparable alteration seen in these indexes before and after the usage of drugs in the control group ( P＞0.05).Positive correlations were found in HLADR expression with OSDI and OSS ( r =0.601,P =0.018 ; r =0.586,P =0.022 ) and a negative correlation in HLADR expression with BUT (r=-0.697,P=0.004) on day 15 in the trial group.ConclusionsTopical usage of 0.1％ pranoprofen is beneficial for remitting the ocular signs and symptoms in moderate to severe dry eyes.This study illustrates that topical usage of 0.1％ pranoprofen can down-regulate the expression of inflammatory markers in conjunctival epithelial cells.

Change of serum high sensitive C-reactive protein level in patients with pathologic myopia / 中华实验眼科杂志

Background Pathologic myopia is one of the common blinding eye diseases.Recent research suggests that immune response participates in the pathogenesis of pathologic myopia,and inflammation is an important factor that influent immune status.Objective Present study was to observe the change of high sensitive C-reactive protein(hs-CRP) in serum in the patients with pathologic myopia and explore the role of inflammation in the development of pathologic myopia. Methods Serum hs-CRP was measured from 30 patients with pathologic myopia,30 patients with simple myopia and 30 normal controls with Nephelometric Turbidity in the OLYMPUS AU5400 automatic biochemical analyzer.Written informed consent was obmined from each subject before medical examination.Results The mean age was(30+10) years in pathologic myopia group,and(32+8)years in simple myopia group and(32+9)years in normal control group.The range of preoperative spherical equivalent refraction was (-6.00--22.00) D in pathologic myopia group,(-1.00--6.00) D in simple myopia group and(-1.00-+1.00) D in normal control group.The level of hs-CRP in serum was(3.68±1.15)mmol/L in the patients with pathologic myopia and was significantly higher than that of simple myopia group(1.99±0.68 mmol/L)and normal controls (2.11±O.66 mmol/L)(q=10.69,P＜0.01;q=9.91,P＜0.01),respectively.No significant correlation was found between hs-CRP level and myopic degrees in pathologic myopia group(R2=0.037,P＞0.05). Conclusion Hs-CRP may play rule in the inflammatory reaction during the pathogenesis of pathologic myopia.

Influence of Shenfu Injection on the quality of life of lung cancer patients receiving chemotherapy / 南方医科大学学报

<p><b>OBJECTIVE</b>To evaluate the influence of Shenfu Injection (SHF) on the quality of life of patients with advanced non-small cell lung cancer (NSCLC) receiving chemotherapy.</p><p><b>METHODS</b>A total of 133 patients with NSCLC receiving at least two cycles of chemotherapy with taxol plus cisplatin (TP)/vinorelbine plus cisplatin (NP) or gemcitabine plus cisplatin (GP) were randomized into SHF pre-treatment group (with SHF given only in the first cycle) and SHF post-treatment group (with SHF given only in the second cycle). The Quality of Life Questionnaire-Core 30 (QLQ-C30) and the Functional Living Index-Cancer (FLIC) were used to evaluate the quality of life of the patients after the treatments.</p><p><b>RESULTS</b>Both of the groups showed improved quality of life after the treatments (P<0.01), but the improvements were more obvious in SHF pre-treatment group (P<0.05). SHF showed favorable effects in relieving such adverse effects as fatigue, nausea, vomiting and diarrhea associated with the chemotherapy.</p><p><b>CONCLUSION</b>SHF can improve the quality of life in NSCLC patients receiving chemotherapies.</p>
