Objective To study the early diagnostic predictors and key follow-up parameters for girls with rapidly progressive central precocious puberty (RP-CPP). Methods A total of 260 girls with CPP participated in a prospective, nonrandomized, multi-center, nested case control study. After follow-up six months without any therapy, 114 girls were divided into RP-CPP (n=70) and slowly progressive CPP (SP-CPP) (n=44) groups. Results The basal serum LH and insulin-like growth factor Ⅰstandard deviation score (IGF-ⅠSDS) were the important risk factors of RP-CPP (OR 4.04, 1.578), especially the former. The receiver operating characteristic (ROC) curve revealed that the areas under the ROC curve of basal LH and IGF-ⅠSDS were 0.83 and 0.807, respectively. The levels of basal LH and IGF-ⅠSDS were at 0.52 mIU/ml and 0.35 respectively for the accuracy diagnosis of RP-CPP with the maximum Youden indexs. After follow-up for six months, the change levels of height, breast stages, bone age/chronological age ratio, serum LH, uterine and ovarian volume in RP-CPP group were significantly higher than those in SP-CPP group (all P<0.05). Conclusions The level of basal serum LH and IGF-ⅠSDS may be used as the risk predictors for early diagnosis for girls with RP-CPP. The change levels of basal LH, progress rates of gonad and sex character, height, and impaired growth potential seem to be the key follow-up parameters for CPP progress.

Objective To study the impact of maternal and infant bedside nursing on promoting the parenting skills of puerperae and their families. Methods A total of 421 pairs of mothers and infants hospitalized in our department from June to July 2013 were selected as the observation group and received maternal and infant bedside nursing; all the nursing procedures and health education were conducted at the bedside for the mothers and neonates by responsible nurses and relevant publicity materials were given out. 410 pairs of mothers and infants hospitalized in our department from June to July 2011 were selected as the control group and received traditional nursing. Results The satisfaction de-gree of the observation of was 96.43% and that of the control group was 89.76%, with statistically significant difference (P<0.01); the puerperae and their families of the observation group had significantly better parenting skills than the control group. Conclusion Maternal and infant bedside nursing can increase the nursing satisfaction and promote the parenting skills of puerperae and their families, thereby worthy of clinical promotion and application.

Objective:To analyze the gene mutation types and haematological characteristics of αβ compound thalassemia, non-delectable α-thalassemia and Hemoglobin H Disease (HbH disease) in Foshan.Methods:Using the method of retrospective analysis, we selected the population who had been tested for thalassemia gene in Foshan Second People's Hospital Affiliated to Southern Medical University from January 2011 to November 2019. Sysmex XT-5000 automatic hematology analyzer was used for routine blood analysis. α-, β- thalassemia genes were detected by PCR + diversion hybridization method.Results:A total of 4 563 people were tested, of which 1 829 were diagnosed as thalassaemia through genetic diagnosis. αβ compound thalassaemia was detected in 81 cases with a positive rate of 1.8%; non-delectable α-thalassemia was detected in 18 cases with a positive rate of 0.4%; HbH disease was detected in 23 cases with a positive rate of 0.5%. The most common genotypes of αβ compound thalassemia were -- SEA/αα\β41-42/βN (17.3%, 14/81), -α 3.7/αα\β41-42/βN (14.8%, 12/81), -- SEA/αα\β654/βN (11.1%, 9/81). The main manifestations of hematology were normal to mild anemia (93.8%, 76/81). Only β-thalassemia with double heterozygotes and α-thalassemia showed severe anemia. αα CS/αα\βN/βN genotypes were common in the local non delectable α-thalassemia (50.0%, 9/18), and the non delectable α-thalassemia was characterized by non-positive phenotype or typical small-cell hypochromatosis in hematology. The genotypes of local HbH patients were -α 3.7/-- SEA\βN/βN (65.2%, 15/23), and simple HbH manifested as moderate anemia (87.0%, 20/23). Patients with HbH disease and β-thalassemia had normal or mild anemia (13.0%, 3/23). Conclusions:The genotypes of αβ compound thalassemia in Foshan area are diverse and complex, and hematology mainly manifests as mild anemia or normal. Non-delectable α-thalassaemia is common in the genotype of αα CS/αα\βN/βN, and clinical manifestations are asymptomatic gene carriers. The genotype of local HbH patients is mainly -α 3.7/-- SEA\βN/βN, and the hematology mainly shows moderate anemia.

Objective:To investigate the clinical features, diagnosis and treatment of lymphoplasmacytic lymphoma (LPL) with biclonal M protein.Methods:The clinical data of one LPL patient with biclonal M protein at Yancheng First People's Hospital in January 2018 was retrospectively analyzed, and relevant literature was reviewed.Results:The patient was an elderly woman with clinical manifestations of lymphadenopathy, kidney damage, anemia, and bone destruction. The diagnosis was confirmed based on lymph node biopsy, immunofixation electrophoresis, bone marrow cytology, and genetic mutation testing (MYD88 L265P mutation-positive). Partial remission was achieved after 4 courses of treatment with bortezomib-based regimen.Conclusions:Clinically, LPL with biclonal M protein shows one characteristic of M protein, and the immunoglobulin IgM and IgA biclonal LPL is even rarer. The treatment scheme based on bortezomib has a certain therapeutic effect.

Objective To cultivate and breed laboratory cats in conventional laboratory animal facilities, collect background data on laboratory cats, and compare them with purchased domestic cats to assess the feasibility of breeding laboratory cats. Methods Indigenous cat breeds were introduced for reproduction and population expansion under conventional laboratory environment, with recording of kitten survival rates and growth curves. Indicators of 20 laboratory cats of F1 generation (half male and half female), including complete blood count, blood biochemistry, organ mass, organ coefficient, heart rate, and blood pressure, were detected and comparisons between sexes were made. Blood pressure values and sensitivity to histamine of these cats were measured using depressor substance detection method in the Pharmacopoeia of the People's Republic of China-Four Parts: 2020, and were compared with the data from 173 concurrently purchased domestic cats. Results Laboratory cats adapted well to the environment of conventional laboratory facilities, with a survival rate of 77.08% of kittens at 8 weeks of age. Red blood cell count, hemoglobin content, mean corpuscular hemoglobin concentration, and hematocrit in male laboratory cats were significantly higher than those in females (P<0.01), while the mean corpuscular volume in males was significantly lower than that in females (P<0.01). The levels of serum alanine aminotransferase, total bilirubin, creatinine, triacylglycerol, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol in male laboratory cats were significantly higher than those in females (P<0.05 or P<0.01), while cholesterol, globulin, total protein, and the albumin-globulin ratio were significantly lower in males (P<0.01). The liver coefficient in male laboratory cats was significantly lower than that in female cats (P<0.05), while the kidney coefficient was significantly higher (P<0.05). The spleen-brain and kidney-brain ratios were significantly higher in males compared to females(P<0.05 or P<0.01). No significant differences were found in heart rate, systolic pressure, diastolic pressure, mean blood pressure, or sensitivity to histamine between male and female laboratory cats (P>0.05). Compared to laboratory cats, purchased domestic cats had significantly higher heart rate, systolic pressure, and mean blood pressure (P<0.01), and the magnitude of blood pressure changes induced by medium and high doses of histamine was significantly reduced (P<0.05 or P<0.01). Conclusion It is feasible to breed laboratory cats in conventional laboratory animal facilities. The accuracy of experimental results can be improved by using laboratory cats with clear and standardized background data.

Objective: To study the clinicopathological features and therapeutic regimens of primary testicular lymphoma (PTL). Methods: The clinical data of 16 patients diagnosed with PTL from January 2005 to December 2015 in Jiangsu Province Hospital were collected, and the clinicopathological characteristics were retrospectively analyzed. Kaplan-Meier method was used to make the survival analysis. Results: The median onset age of 16 patients was 63 years old (33-81 years old). According to Ann Arbor stage, there were 8 cases of stage Ⅰ_E, 2 cases of stage Ⅱ_E, 6 cases of stage Ⅲ-Ⅳ. The initial symptoms included painless solid enlargement of the testis (9 cases), painful testis (3 cases), distending pain of testis (1 case), and the patients had no other systemic symptoms. The pathological type was diffuse large B-cell lymphoma (DLBCL), of which 2 patients were germinal center B-cell (GCB) type and the other 14 patients were non-GCB type. All the patients received the orchiectomy, of which 14 received chemotherapy alone after the operation, 2 received chemotherapy and radiotherapy. Complete follow-up data were available for 14 patients, and the median follow-up time was 23.5 months (1.0-97.0 months). Among 14 patients, complete remission was achieved in 11 patients, partial remission in 1 patient, no response in 1 patient, and 1 patient was undergoing treatment. Among 11 patients with complete remission, 5 patients relapsed, and the recurrence occurred at the central nervous system (3 cases), skin of right lower extremity (1 case), and contralateral testis (1 case). The mean progression-free survival (PFS) time was 19.0 months (14.0-95.0 months). Conclusions Most PTL is primary testis DLBCL, and the comprehensive treatment based on surgery is the main therapy of PTL. Postoperative chemotherapy with or without radiotherapy is recommended to prevent relapse.
