Objective To evaluate our experience in the diagnosis and surgical management of papillary thyroid microcarcinoma(PTMC). Methods Clinical data of 42 PTMC cases were retrospectively analyzed. Results Twenty-five clinically nonpalpable PTMC were detected by high resohition thyroid uhrasonography preoperatively.The diagnosis of PTMC was established intraoperatively by frozen biopsy in 14 out of 19 cases undergoing this procedure.Of the 42 patients,30 underwent a lobectomy,and in 11 out of 30 patients supplemented level Ⅵ lymph node dissection was performed.None of these patients had recurrence during follow-up.The recurrence in three patients with multffocal lesions and undergoing incomplete resection were observed at follow.up.The mulifocality of PTMC and ipsilateral residual volume of the thyroid were two predicting factors that significantly influence the postoperative recurrence(P＜0.05,P＜0.01 respectively)in patients with PTMC. Candus-ions PTMC is usually occult and eludes correct preoperative diagnosis.Most PTMC are clinically nonpalpable and may be detected by hish resolution thyroid ultrasonography and diagnosed by frozen section during the operation.Surgery is the most important treatment of PTMC.Lobectomy plus level Ⅵ lymph node dissection is the therapy of choice for PTMC patients at the stage of cN0.

Objective To analyze the etiology and treatment of autoimmune hemolytic anemia. Methods The clinical data of 29 children with autoimmune hemolytic anemia during January 2013 to December 2015 were retrospectively analyzed. Results In 29 children, 10 cases were idiopathic 19 cases were secondary and 11 cases occurred after infections. The main clinical manifestations were pallor, jaundice, dark urine, and hepatosplenomegaly. 21 cases were Coombs test positive. In 29 children, 22 cases had a good response to adrenocortical hormone therapy while in 7 cases which had not response to adrenocortical hormone, good efficacy was achived after combined with the gamma globulin treatment. Conclusions The first line drug for autoimmune hemolytic anemia treatment is adrenocortical hormone. The gamma globulin can improve the efficacy.

Objective: To observe the effects of acupoint sticking therapy of different dosages and durations on the subjective and objective sleep indicators in insomnia patients.Methods: Ninety-six patients with insomnia due to liver-Qi stagnation and spleen deficiency were divided into a high-dosage 7 d group (25 cases), a high-dosage 14 d group (22 cases), a low-dosage 7 d group (21 cases), and a low-dosage 14 d group (28 cases) using the random numbers generated in a stratified and stage-by-stage manner in combination with the visiting sequence. The four groups all received the same acupuncture treatment, but acupoint sticking therapy varied in dosage and duration. Before and after treatment, the actigraphic readings (total time in bed, total sleep time, sleep efficiency, number of wake bouts, length of wakes after asleep, and sleep latency), Pittsburgh sleep quality index (PSQI) score, and symptoms score of traditional Chinese medicine (TCM) were observed. A correlation analysis was conducted among the subjective and objective indicators. Results: The PSQI score was positively correlated with the total time in bed and total sleep time (P<0.05). After treatment, the sleep latency, PSQI scores, and TCM symptoms scores changed significantly in the four groups (P<0.05). The total sleep time and sleep efficiency gained improvements after treatment in the high-dosage 14 d and low-dosage 14 d groups (P<0.05). The high-dosage acupoint sticking groups had longer total sleep time compared with the low-dosage groups of the same treatment duration (P<0.05). After treatment, the length of wakes after asleep, PSQI scores, and TCM symptoms scores were better in the 14 d groups than in the 7 d groups of the same acupoint sticking dosage (P<0.05). Conclusion: Given the same acupuncture treatment, acupoint sticking therapy of different treatment durations produces different effects on the length of wakes after asleep, PSQI score, and TCM symptoms score in insomnia patients, and the 14-day acupoint sticking treatment is superior to the 7-day treatment.

Objective To investigate the effect of acupuncture combined with antidepressant on behavioral changes and 5-hydroxytryptamine 1A and 2A receptor ( 5-HT1AR and 5-HT2AR) mRNA expression in nucleus raphes dorsalis (NRD) of sleep deprivation depression (SDD) rats. Methods Eight normal Sprague Dawley (SD) rats were caged together without any stimulus or treatment, serving as the normal group. Thirty-two SD rats were given solitary raise for 21 days, together with chronic unpredictable mild stress ( CUMS) and rapid eye movement ( REM) sleep deprivation to establish the model. Twenty-eight rats completed the modeling successfully, and were divided into model group, acupuncture group, medicine group, and combination group, 7 rats in each group. Rats in the model group were given modeling treatment but without any intervention. Rats in the acupuncture group were given acupuncture on acupoint Yintang, Shenting and bilateral Taichong, acupuncture stimulation lasting 15 s every 10 min and acupuncture retention for 20 min in each day. Rats in the medicine group were given gastric gavage of Zoloft solution (0.83 mg·kg-1·d-1) and Alprazolam solution (0.067 mg· kg-1·d-1) , and rats in the combination group were given both acupuncture and medicine intervention. The intervention for the three intervention groups lasted for 7 days. Results Compared with the normal group, body weight, Open-field scores and sucrose preference of the model rats were significantly decreased on modeling day 7, 14, 21 (P<0.05). On modeling day 28, body weight and Open-field scores of each intervention group were significantly increased compared with those of the model group (P<0.05), and Open-field scores of combination group differed from those of acupuncture group and medicine group ( P<0.05). Only sucrose preference of combination group was improved significantly compared with the model group (P<0.05). Compared with the model group, NRD 5-HT1AR mRNA expression level was increased in the combination group (P<0.05), and NRD 5-HT2AR mRNA expression level was down-regulated in all of the three intervention groups ( P<0.05). Conclusion Acupuncture and antidepressant treatment covering 7 days can evoke rapid effect on SDD rats, which can improve the slow effect of antidepressant.

Objective:To observe the effects of kidney-tonifying and mind-calming acupuncture therapy on sleep,mood,sex hormone levels,and traditional Chinese medicine(TCM)symptoms in patients with perimenopausal insomnia(PMI). Methods:A total of 90 patients with PMI were randomly divided into a treatment group and a control group,with 45 cases in each group.Patients in the treatment group were treated with acupuncture at Shenshu(BL23),Taixi(KI3),Baihui(GV20),and Anmian(Extra).The control group was treated with sham acupuncture.Both groups were treated 3 times a week for 4 weeks.Pittsburgh sleep quality index(PSQI)and insomnia severity index(ISI)were used to evaluate the sleep quality of the subjects before treatment,after treatment,and 1 month after treatment(follow-up).Beck depression inventory(BDI)and Beck anxiety inventory(BAI)were used to evaluate the depression and anxiety of the subjects before treatment,after treatment,and at 1-month follow-up.The TCM symptom scale was used to evaluate the TCM symptoms of the subjects before treatment,after treatment,and 1 month after treatment.Serum levels of estradiol(E2),follicle-stimulating hormone(FSH),and luteinizing hormone(LH)were measured before and after treatment. Results:During the study,2 cases dropped out of the treatment group,and no cases dropped out of the control group.The PSQI scores of the treatment group were significantly lower after treatment and at 1-month follow-up compared with those before treatment(P<0.05),and the difference was statistically significant compared with that of the control group(P<0.05).In the control group,the PSQI score was significantly lower after treatment compared with before treatment(P<0.05),and the difference was not statistically significant at 1-month follow-up compared with before treatment(P>0.05).Compared with the pre-treatment,the ISI,BDI,BAI,and TCM symptom scale scores of the treatment group were lower after treatment and at 1-month follow-up(P<0.05),and the differences with the control group at the same time point were statistically significant(P<0.05).The differences in ISI,BDI,BAI,and TCM symptom scale scores of the control group before treatment,after treatment,and at 1-month follow-up were not statistically significant(P>0.05).After treatment,the serum E2 level in the treatment group was significantly higher than that before treatment(P<0.05),and the difference with the control group was statistically significant(P<0.05).The difference in the serum E2 level before and after treatment in the control group was not statistically significant(P>0.05).The differences in the serum FSH and LH levels between before and after treatment were not statistically significant in either group of subjects(P>0.05). Conclusion:Kidney-tonifying and mind-calming acupuncture therapy can improve sleep quality,relieve anxiety and depression,delay the decrease of serum E2 level,and improve related TCM symptoms in patients with PMI.

Background/Aims: Metabolic risk factors could accelerate hepatitis B virus (HBV)-related mortality; however, their impacts on disease severity in HBV-related acute on chronic liver failure (HBV-ACLF) patients remain unexplored. In this study, we assessed the effects of metabolic risk factors on the outcome of HBV-ACLF patients. Methods: This study retrospectively enrolled antiviral therapy naïve HBV-ACLF patients from a single center in China. Patients were evaluated according to Child-Turcotte-Pugh score, Model for End-Stage Liver Disease (MELD) score, 30-day, 90-day mortality and survival rate to estimate the prognosis of HBV-ACLF. The impacts of different metabolic risk factors were further analyzed. Results: A total of 233 patients, including 158 (67.8%) with metabolic risk factors and 75 (32.2%) without metabolic risk factors, were finally analyzed. Patients with metabolic risk factors had significantly higher MELD score (22.6±6.1 vs 19.8±3.8, p<0.001), 90-day mortality rate (56.3% vs 38.7%, p=0.017), and shorter median survival time (58 days vs 75 days: hazard ratio, 1.553; 95% confidence interval, 1.061 to 2.274; p=0.036) than patients without them. Moreover, metabolic risk factors were independently associated with patients’ 90-day mortality (hazard ratio, 1.621; 95% confidence interval, 1.016 to 2.585; p=0.043). Prediabetes/diabetes and hypertension were related to higher rates of infection and worse renal function in HBV-ACLF patients. Conclusions HBV-ACLF patients with metabolic risk factors, especially prediabetes/diabetes or hypertension, could have more severe disease and lower survival rates. In addition, the existence of metabolic disorder is an independent risk factor for HBV-ACLF patients’ 90-day mortality.

Objective To evaluate the effect of different kind of intravenous immunoglobulin (IVIG) therapy in treating Kawasaki disease (KD) and preventing cardiac consequences (coronary artery lesion, CAL). Methods A questionnaire form and guideline for KD diagnosis were sent to 50 hospitals providing pediatric medical care in Shanghai. The data from a total of 1 682 KD patients were collected. It included 1 064 males and 618 females from 1998 through 2008 in Shanghai. The average age of the KD patients was (2.57±2.33) years old (0.1-18.8 years).The patients had been divided into 6 groups for different IVIG therapy, which included 1 g/kg once, 2 g/kg once, 0.4-0.5 g/kg five times, 1 g/kg twice, 2 g/kg twice and others. SAS 6.12 software was used for statistical analysis. Results In all KD patients, the patients treated with IV1G in 5th-10th day of illness has the least cardiac complication and CAL incidence and the group with IVIG therapy of 1 g/kg twice also has the least cardiac complication and CAL incidence. Conclusions The best doses of IVIG in treating KD is 1 g/kg twice and the IVIG therapy should be used in 5th-10th day of KD illness.

OBJECTIVE: To explore the clinical characteristics and molecular genetic mechanism of a fetus with recombinant chromosome 8 (Rec8) syndrome. METHODS: A fetus who was diagnosed with Rec8 syndrome at the Provincial Hospital Affiliated to Shandong First Medical University on July 20, 2021 due to high risk for sex chromosomal aneuploidy indicated by non-invasive prenatal testing (NIPT) (at 21st gestational week) was selected as the study subject. Clinical data of the fetus was collected. G-banded karyotyping and chromosomal microarray analysis (CMA) were carried out on the amniotic fluid sample. Peripheral blood samples of the couple were also subjected to G banded karyotyping analysis. RESULTS: Prenatal ultrasonography at 23rd gestational week revealed hypertelorism, thick lips, renal pelvis separation, intrahepatic echogenic foci, and ventricular septal defect. The karyotype of amniotic fluid was 46,XX,rec(8)(qter→q22.3::p23.1→qter), and CMA was arr[GRCh37]8p23.3p23.1(158049_6793322)×1, 8q22.3q24.3(101712402_146295771)×3. The karyotype of the pregnant woman was 46,XX,inv(8)(p23.1q22.3), whilst that of her husband was normal. CONCLUSION The Rec8 syndrome in the fetus may be attributed to the pericentric inversion of chromosome 8 in its mother. Molecular testing revealed that the breakpoints of this Rec8 have differed from previously reported ones.

Pulmonary hypertension has a high mortality rate,and although targeted therapy is available,it is still incurable,and the long-term prognosis for patients is poor.As a tyrosine kinase inhibitor,imatinib was approved for marketing in China in 2002 for the treatment of chronic myelogenous leukemia and other tumor diseases.In addition to the antitumor effects,imatinib was found to improve hemodynamics and exercise tolerance in patients with severe pulmonary arterial hypertension,but the safety was suboptimal.With the emergence of new formulations of imatinib targeted at the lungs,it is expected to become a new targeted drug for pulmonary arterial hypertension.

To summarize the clinical manifestations of a case with 46, XY sex development disorder caused by myelin regulatory factor(MYRF) gene mutation and review the literature to deepen the specialists′ understanding of the clinical disease spectrum resulting from MYRF gene variations. The child had a female phenotype with mild masculinity, chromosome 46, XY, sex-determining region of Y gene(SRY gene) positive, laboratory tests were consistent with primary hypogonadism, ultrasound did not detect the gonads, but the residual reproductive tract was visible, and echocardiography suggested coarctation of the aorta, MYRF gene c. 2518C>T(p.R840*) heterozygous variant. The father did not carry this variant. The mother was untraceable, and genetic testing had not been completed. It was analyzed as pathogenic variation according to American College of Medical Genetics and Genomics(ACMG) guidelines. Sixteen cases of disorders of sex development caused by MYRF gene variation reported from 2018 to 2021 were reviewed, MYRF gene variants, 46, XY, and 46, XX individuals can be pathogenic, can affect the gonad and reproductive tract at the same time, and can also affect multiple systems. In this case, the patient presents with 46, XY sex development disorder due to MYRF gene mutation, accompanied by rare cardiovascular complications. When encountering 46, XY primary hypogonadism without well-developed Müllerian duct structures, this condition should be considered. Following confirmation, a comprehensive assessment of multi-organ function is necessary.
