Objective To explore the differential diagnosis of hydrops fetalis and the rare presentations of neonatal congenital hypothyroidism. Methods The data of one congenital hypothyroidism diagnosed neonate with hydrops fetalis leading to birth asphyxia and respiratory failure were retrospectively analyzed. The relevant literatures were reviewed. Results A Uyghur female infant by cesarean delivery at gestational age of 38+5 week for intrauterine distress, presented general edema with cyanosis and dyspnea after birth. Trachea cannula was used to assist ventilation. At one-day old, the thyroid function examination showed that the serum thyroid stimulating hormone was>100 mU/L and the free thyroid was 6 . 56 pmol/L. Moreover, ultrasonographic examination indicated the thyroid aplasia. The clinical symptoms were improved after the treatment with the levothyroxine tablets replacement, and breathing machine was removed at 8-day old. The dosage of drug was adjusted by clinical manifestation and laboratory monitoring. The patient was discharged at 18-day old with the medicine and was followed-up. Conclusions Congenital hypothyroidism can be the pathogenesis of hydrops fetalis and its differential diagnosis should be paid attention.

Objective : To investigate the epidemiological characteristics of influenza among the elderly in Heilongjiang Province from 2017 to 2021 (April 2017 to March 2022), so as to provide insights into influenza control among the elderly. Methods : The data pertaining to surveillance of patients with influenza-like illness (ILI) at ages of 60 years and older in Heilongjiang Province from 2017 to 2021 were retrieved from Chinese Influenza Surveillance Information Management, and the temporal distribution of ILI cases and the results of influenza virus tests were descriptively analyzed. Results : Totally 26 908 ILI cases at ages of 60 years and older were reported in Heilongjiang Province from 2017 to 2021, with an ILI prevalence rate of 0.17%. The prevalence of ILI appeared a tendency towards a rise in Heilongjiang Province from 2017 to 2021 (χ2trend=268.554, P<0.001), and the epidemic peaked in the 3rd to 7th weeks of 2019 and 2020. The overall positive rate of influenza virus was 6.80%, and the positive rate of influenza virus showed a tendency towards a decline from 2017 to 2021 (χ2trend=425.268, P<0.001). Influenza A (H1N1) pdm09 (46.82%) and A (H3N2) (22.79%), as well as influenza B virus lineages B/Victoria (12.11%) and B/Yamagata (18.28%) were predominant types, which changes among the study period. The detection of influenza virus-positive samples peaked from December to March of the next year, and a high positive rate of influenza virus was detected in Hegang (12.35%), Heihe (11.47%) and Daqing cities (11.07%). There was no significant correlation between the prevalence of ILI and the positive rate of influenza virus in Heilongjiang Province from 2017 to 2021 (rs=-0.800, P=0.104). Conclusions The prevalence of ILI appeared a tendency towards a rise among the elderly at ages of 60 years and older in Heilongjiang Province from 2017 to 2021, and the epidemic peaked in winter and spring. Influenza A (H1N1) pdm09, A (H3N2), B/Victoria, B/Yamagata were alternately prevalent and there was no obvious correlation between ILI prevalence and the positive rate of influenza virus.

Objective To study the clinicopathologic features of brain tumors in patients with medically intractable epilepsy. Methods The clinical, radiologic and pathologic features of brain tumors in thirty-six patients with intractable epilepsy encountered during the period from 2008 to 2014 in the Epilepsy Center of Haidian Hospital were retrospectively reviewed. Results There were 18 males and 18 females in thirty-six patients. The mean age of seizure onset and disease duration were (14.05 ± 1.67) years and (10.04 ± 1.19) years respectively. The histological types of brain tumors included ganglioglioma (12/36, WHO gradeⅠ,1/36, WHO gradeⅡ), dysembryeplastic neuroepithelial tumor (2/36, WHO gradeⅠ), pleomorphic xanthoastrocytoma (1/36, WHO gradeⅡ), angiocentric glioma (1/36, WHO gradeⅠ), astrocytoma (4/36, WHO gradeⅡ), oligoastrocytoma (1/36, WHO gradeⅡ, 2/36, WHO gradeⅠ-Ⅱ), oligodendroglioma (1/36, WHO gradeⅠ-Ⅱ,1/36, WHO grade Ⅱ), cavernous hemangioma (4/36) and Sturge-Weber syndrome (1/36). Most of these tumors were located in temporal lobe (25/36, 69.4%). Patients were followed up for 0.5-7 years after operation. One patient was lost for follow up. Seizure outcome after the epilepsy operation revealed that 28 patients (77.8%) had Engel gradeⅠ, 4 patients (11.1%) had Engel gradeⅡ,2 patients (5.6%) had Engel gradeⅢ,1 patient (2.8%) had Engel gradeⅣ. Conclusion Brain tumors in patients with medically intractable epilepsy are almost low grade tumors of the nervous system. Focal cortical dysplasia is existed in most brain tissues from the epilepsy operation. Low grade tumors of the nervous system have close relation with focal cortical dysplasia in patients with medically intractable epilepsy. It is possible that the classifications of pathology diagnosis has connection with prognosis.

Objective To study the relationship between pain symptoms and the clinico-pathological features of pelvic endometriosis (EM).Methods One hundred thirty patients with laparoseopic diagnosis of EM were studied retrospectively and the relationship between pain symptoms including dysmenorrhea, chronic pelvic pain(CPP),dyspareunia and dysehezia and the anatomical features of pelvic endometriosis were evaluated.Results One hundred (76.9%)patients with pain symptoms and 30 (23.1%)without were included in this study.The number of patients with mild,moderate and severe dysmenorrhoea was 27 (20.8%),41(31.5%),and 32 (24.6%),respectively.Patients with dyspareunia,CPP and dyschezia were 46(35.4%),45(34.6%) and 67(51.5%),respectively.Compared with patients without dysmenorrhea,the proportion of deep utero-sacral nodules (45.0% vs 13.3%,P=0.00),recto-vaginal nodules (16.0% vs 0,P=0.01),complete obliteration of eul-de sac (41.0% vs 10.0%,P=0.00),and lesions of DIE (51.0% vs 16.7%,P=0.00) was significantly increased in patients with dysmenorrhea. The severity of dysmenorrhea was positively correlated with nodules in uterosacral ligaments (P=0.005,r= 0.302),and invasive depth of uterosacral ligaments (P=0.016,OR=5.085).Among patients with endometrioma,significantly more moderate to severe adhesions were found in patients with dysmenorrhea , compared with those patients without dysmenorrhea(29.1% vs 8.3%,P=0.029).Patients with CPP had more nodules in the utero-sacral ligaments(51.1% vs 30.6%,P=0.018)and DIE lesions(57.8% vs 35.3%,P=0.011),compared with those without.More nodules in the utero-saeral ligaments(46,3% vs 28.6%,P=0.028),recto-vaginal nodules(19.4% vs 4.8%,P=0.01),complete obliteration of cul-de sac(44.8% vs 22.2%,P=0.005)and DIE lesions(53.7% vs 31.7%,P=0.01)were found in patients with dyschezia,compared with those without.Nodules in the recto-vaginal pouch were an independent risk factor of dyspareunia.Conclusion Pain symptoms including dysmenorrhea,dyspareunia, chronic pelvic pain,and dysehezia are remarkedly related to endometriotic nodules at the posterior part of the pelvis or those with deep invasions.

OBJECTIVETo explore the intervention of Huayu Qutan Recipe (HQR) on liver SREBP-2 signal pathway of hyperlipidemia rats of Pi deficiency syndrome (PDS).

METHODSTotally 100 SPF grade SD rats were randomly divided into the blank control group, the hyperlipidemia group, the hyperlipidemia treatment group, the PDS hyperlipidemia group, and the PDS hyperlipidemia treatment group, 20 in each group. Common granular forage was fed to rats in the blank control group. High fat forage was fed to rats in the hyperlipidemia group and the hyperlipidemia treatment group. Rats in the PDS hyperlipidemia group and the PDS hyperlipidemia treatment group were treated with excessive labor and improper diet for modeling. They were administered refined lard by gastrogavage (3 mL each time, twice per day) and fed with high fat forage on the odd days, and fed with wild cabbage freely on even days. The modeling lasted for 30 days. Rats in the hyperlipidemia treatment group and PDS hyperlipidemia treatment group were administered with Huayu Qutan Recipe (20 mL/kg) by gastrogavage, once a day, for 30 successive days. Levels of serum cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), and serum amylase (AMY) were detected by automatic biochemical analyzer. D-xylose excretion rate was determined using phloroglucinol method. Morphological changes of liver and the lipid deposition in liver were observed using HE stain and oil red O stain respectively, mRNA and protein expression levels of 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR), cholesterol 7α-hydroxylase 1 (CYP7A1), LDL-R, and sterol regulatory element binding protein-2 (SREBP-2) were detected using real time RT-PCR and Western blotting.

RESULTSCompared with the blank control group, serum levels of TC (1.84 ± 0.19 mmol/L, 2.23 ± 0.43 mmol/L) and LDL-C (0.99 ± 0.24 mmol/L, 1.13 ± 0.56 mmol/L) were higher in the hyperlipidemia group and the PDS hyperlipidemia group, serum levels of HDL-C (0.41 ± 0.66 mmol/L, 0.41 ± 0.11 mmol/L) and AMY activities (351 ± 45 mmol/L, 153 ± 30 mmol/L) were lower, and urinary D-xylose excretion rates were lower (26.9 ± 2.1 ng/mL, 15.0 ± 1.7 ng/mL) (all P < 0.05). Lipid deposition occurred in liver cells. Much fat vacuoles occurred in the cytoplasm. Expression levels of HMGCR, CYP7A1, LDL-R, and SREBP-2 mRNA and proteins in liver significantly decreased (P < 0.01). Compared with the hyperlipidemia group, serum levels of TC and LDL-C significantly increased (P < 0. 05), AMY activities and urinary D-xylose excre- tion rates significantly decreased in the PDS hyperlipidemia group (P < 0.01). A large amount of lipid deposition occurred in liver. The atrophy of liver cells was obviously seen. Expression levels of CYP7A1, LDL-R, and SREBP-2 mRNA and proteins in liver were significantly lower (P < 0.01, P < 0.05). Serum levels of TC and LDL-C significantly decreased (P < 0.05), AMY activities and urinary D-xylose excretion rates significantly increased in the hyperlipidemia treatment group (P < 0.01). Expression levels of CYP7A1, LDL-R, and SREBP-2 mRNA and proteins in liver were significantly increased (P < 0.01, P < 0.05). Compared with the PDS hyperlipidemia group, serum level of TC significantly decreased (P < 0.05), HDL-C levels, AMY activities and urinary D-xylose excretion rates significantly increased in the PDS hyperlipidemia treatment group (P < 0.01),expression levels of CYP7A1, LDL-R, and SREBP-2 mRNA and proteins in liver were significantly increased (P < 0.01). Similar changes occurred in the two treatment groups.

CONCLUSIONSPi deficiency exacerbates abnormal serum TC level and the lipid deposition in liver. These might be related to regulating expression levels of LDL-R, HMGCR, and CYP7A1 genes in the SREBP-2 signal pathway. HQR could regulate this pathway to intervene abnormal metabolism of TC.

OBJECTIVETo investigate the effects of Huanglian Jiedu (HLJD) decoction on vascular endothelial function in type 2 diabetic rats and explore the prophylactic and therapeutic significance and pharmacological mechanism of HLJD decoction in type 2 diabetic angiopathic complication.

METHODThe murine type 2 diabetes models were induced by the intravenous injection of a small dose of streptozotocin plus high fat and high caloric laboratory chow. Then modeled diabetic animals were divided into model group, HLJD group, and aspirin group. Normal ratsfed with routine chow were designated as normal group. The oral glucose tolerance test (OGTT) were performed in all animals, 9 weeks after treatment, the changes of murine body weights and levels of fasting blood glucose (FBG), serum total cholesterol (TC), triglycerides (TG), high density lipoprotein-cholesterol(HDL-C), fasting serum insulin (FINS), serum nitric oxide, plasma endothelin, angiotensin II and von Willebrand Factor (vWF) were determined 10 weeks after treatment.

RESULTCompared with model group, the result of OGTT of HLJD group was improved. The levels of the body weights, TC, TG and ET in HLJD group weredecreased (P < 0.05). The levels of FBG,INS, AngII and vWFwere significantly decreased (P < 0.01), and the levels of HDL-C and NO were obviously increased (P < 0.05), as compared with those in model group. Furthermore. The levels of FBG was lower in HLJD group than in aspirin group (P < 0.05), and the improvement of TG, HDL-C,NO, AngII, vWF levels in HLJD group was more greatly than that in aspirin group, but there was not significant difference between two groups (P > 0.05).

CONCLUSIONIt is suggested by the present results that HLJD decoction could protect vascular endothelium from early damage in type 2 diabetes. The protective effects of HLJD on endothelium might be related to its ability of reducing the blood glucose, adjusting plasma lipids profiles, improving insulin resistance, antagonizing inflammatory mediators and inducing endothelium-dependent vascular relaxation.

BACKGROUNDEndometriosis (EM) is a benign gynecologic disease predominantly found in women of reproductive age. However, its pathogenesis is still poorly understood. Our experiment was designed to establish a stable and reliable cultural environment for coculture of endometrium and peritoneum, so as to observe the adhesion/invasion ability of endometrium from patients with or without EM.

METHODSEndometria of secretory phase and peritoneum were sampled from 6 women with endometriois during laparoscopy. Six with ovarian teratoma or simple ovarian cyst were taken as control. We cocultured endometrium and peritoneum into four groups (endometrium from EM cultured with peritoneum from EM, endometrium from control cultured with peritoneum from control, endometrium from EM cultured with peritoneum from non-EM and the endometrium from control cultured with peritoneum from EM) to observe the adhesion/invasion process in gas-liquid surface culture and in-medium culture. Specimens were collected at 1 hour, 6 hours, 12 hours, 24 hours, 2 days, 3 days, 4 days, 5 days, 6 days and 7 days for histology, immunofluorescence and immunohistochemical analysis on cytokeratin 8 (CK8) and CD10.

RESULTSThe gas-liquid surface culture was superior to in-medium culture for the maintenance of tissue morphology and survival of endometrium. CK8 immunoflurescence demonstrated no remarkable difference in adhesion process between patients with and without EM. CD10 immunochemistry manifested frequent invasion of endometrial stromal cells from EM patients into peritoneum of up to 3 days culture, while the endometriotic cells from non-EM patients did not invade into peritoneum.

CONCLUSIONSGas-liquid surface culture is a suitable model for observing the early events in EM lesion formation. Endometrium from patients with EM showed increased invasion capacity during coculture, which might help to explain the etiology of endometriosis.

BACKGROUNDEndometriosis is a controversial and enigmatic disease. Deep infiltrating endometriosis (DIE) is responsible for painful symptoms and is the least understood type of endometriosis. Little work has been devoted to define the location of DIE lesions and its relationships with pain. The aim of the study was to investigate the relationship between the anatomical distribution of DIE lesions and pain symptoms.

METHODSClinical data from 354 patients between May 2003 and December 2007 with laparoscopically diagnosed endometriosis were collected including 177 DIE patients and 177 non-DIE patients. The pain symptoms, including dysmenorrhea (DM), chronic pelvic pain (CPP, defined as intermittent or permanent pelvic pain, not related to the menstruation and longer than 6 months), deep dyspareunia (pelvic pain at intercourse) and dyschezia (pelvic pain with defecation), were recorded for every patient before operation. Endometriotic lesions were recorded by their anatomical distributions, the depth of infiltration and lesion colors. And the relationship between the anatomical distribution of DIE lesions and pain symptoms was analyzed. Pearson's chi-square test or Fisher's exact test, one-way analysis of variance (ANOVA) and linear regression and binary Logistic regression were used for statistical analysis.

RESULTSThe duration ((13.79 ± 3.94) years) of pain suffering in DIE patients was much longer than that of non-DIE patients (P < 0.01). In DIE patients, 60.7% of the uterosacral ligament (USL) nodules were bilateral (P < 0.01); 44.6% of the cul-de-sacs were completely blocked. Rectum invasion was observed in 19.9% of DIE patients (P = 0.03); pelvic adhesion was also more common. Up to 98.41% of the deep infiltrative lesions were located in the posterior pelvic compartment. DIE lesions were also found in bladder (1.58%), USL (67.08%), cul-de-sac (12.02%), recto-vaginal septum (12.66%), rectum and rectosigmoid junction (2.85%) and ureter (3.80%). The odds ratio of USL-DIE for CPP, deep dyspareunia, dyschezia were 2.52, 1.29 and 2.24 respectively. And the depth of infiltration correlated with the severity of dysmenorrhea.

CONCLUSIONSDIE lesions were associated with severe pain symptoms. The main distribution of DIE lesions was in the posterior pelvic compartment, and was more widespread and severe in DIE patients. Moreover, resection of these DIE lesions are very important to treat the pain symptoms.

BACKGROUND:The outcome of cardiopulmonary resuscitation (CPR) may depend on a variety of factors related to patient status or resuscitation management. To evaluate the factors influencing the outcome of CPR after cardiac arrest (CA) will be conducive to improve the effectiveness of resuscitation. Therefore, a study was designed to assess these factors in the emergency department (ED) of a city hospital.METHODS:A CPR registry conforming to the Utstein-style template was conducted in the ED of the First Affiliated Hospital of Wenzhou Medical College from January 2005 to December 2011. The outcomes of CPR were compared in various factors groups. The primary outcomes were rated to return of spontaneous circulation (ROSC), 24-hour survival, survival to discharge and discharge with favorable neurological outcomes. Univariate analysis and multivariable logistic regression analysis were performed to evaluate factors associated with survival.RESULTS:A total of 725 patients were analyzed in the study. Of these patients, 187 (25.8％) had ROSC, 100 (13.8％) survived for 24 hours, 48 (6.6％) survived to discharge, and 23 (3.2％) survived to discharge with favorable neurologic outcomes. A logistic regression analysis demonstrated that the independent predictors of ROSC included traumatic etiology, first monitored rhythms, CPR duration, and total adrenaline dose. The independent predictors of 24-hour survival included traumatic etiology, cardiac etiology, first monitored rhythm and CPR duration. Previous status, cardiac etiology, first monitored rhythms and CPR duration were included in independent predictors of survival to discharge and neurologically favorable survival to discharge.CONCLUSIONS:Shockable rhythms, CPR duration ≤15 minutes and total adrenaline dose ≤5 mg were favorable predictors of ROSC, whereas traumatic etiology was unfavorable. Cardiac etiology, shockable rhythms and CPR duration ≤15 minutes were favorable predictors of 24-hour survival, whereas traumatic etiology was unfavorable. Cardiac etiology, shockable rhythms, CPR duration ≤15 minutes were favorable predictors of survival to discharge and neurologically favorable survival to discharge, but previous terminal illness or multiple organ failure (MOF) was unfavorable.

OBJECTIVETo study the surgical management of solid-pseudopapillary tumor of the pancreas (SPTP) and its characteristics of outcome.

METHODSFifty-eight patients with SPTP of the pancreas admitted from January 2001 to December 2010 were retrospectively analyzed. There were 7 male and 51 female patients, with an average age of 30 years (ranging 9 to 70 years). Most patients were symptomatic before admission; the most common symptom was abdominal pain. Of the 58 patients, 21 patients underwent pancreaticoduodenectomy, 30 patients underwent distal pancreatectomy, 6 patients underwent central pancreatectomy, 1 patient underwent simple tumor enucleation, and 1 patients underwent duodenum-preserving pancreatic head resection.

RESULTSThe average length of stay in hospital was 23.8 days (ranging 12 to 64 days). Thirteen patients (22.4%) developed postoperative complications, including grade A postoperative pancreatic fistula of 8 cases, gastrointestinal tract bleeding of 1 case, pleural effusion of 2 cases, wound infection and fat liquefaction of 2 cases. Two patients underwent reoperation due to gastrointestinal tract bleeding or wound infection. There was no hospital death. Forty-four patients were followed-up for 7 to 136 months with an average of 41 months. All the 44 patients were alive, while 8 patients developed dyspepsia and 4 patients developed diabetes mellitus. There were no tumor recurrences or metastasis.

CONCLUSIONSSPTP is found primarily in young women. Excellent prognosis would be achieved with surgical resection.
