OBJECTIVETo investigate the hypoglycemic characteristics of hospitalized elderly patients with type 2 diabetes mellitus (T2DM).
METHODSFrom January, 2014 to December, 2015, the data of 58 565 blood measurements using a standard blood glucose monitoring system (BGMS) were collected from 1187 cases of patients with type 2 diabetes during hospitalization in the Department of Endocrinology, Guangdong General Hospital (Guangzhou, China). Stratified analyses were conducted by dividing the patients into 3 age groups, namely <45 years group (128 cases), 45-64 years group (594 cases), and ≥65 years group (465 cases). The incidence and time distribution of hypoglycemia in these patients were compared among the 3 age groups.
RESULTSThe risk of hypoglycemia increased with age. Compared with those below 45 years of age, the patients beyond or equal to 65 years had a significantly increased hypoglycemic density (0.95% vs 0.40%, P<0.001), a higher proportion of patients with hypoglycemia (28.17% vs 10.94%, P<0.001), and greater patient-days with hypoglycemia (4.48% vs 1.76%, P<0.001). In the elderly patients, hypoglycemia occurred most frequently before dawn, at which time the hypoglycemic density was 2.66% in patients ≥65 years of age, significantly higher than that in patients below 45 years (1.09%, P<0.05) and between 45 and 64 years (1.90%, P<0.05); the proportion of patients with hypoglycemia was also significantly higher in the elderly patients (14.57%) than in those below 45 years (3.77%, P<0.02) and between 45 and 64 years (9.42%, P<0.02). The proportion of patients with recurrent hypoglycemia (≥2 times) was significantly higher in patients ≥65 years (13.33%) than in younger patients (2.34% in <45 years group and 9.43% in 45-64 years group, P<0.05).
CONCLUSIONThe hypoglycemic risk in hospitalized elderly patients with T2DM is significantly higher than that in younger patients, especially before dawn and in terms of recurrent hypoglycemia. Clinicians should develop differential blood glucose monitoring and management strategies for these elderly patients to improve the clinical safety.

Objective The active ingredient was used as index to optimize the extraction and enrichment process of anti-in-flammatory and analgesic active-fraction(ARF)of Dianbaizhu. Methods Methyl salicylate triglycoside-B was chosen as index com-ponent to extract and enrich methyl salicylate glycosides. Extraction and elution solvents were optimized. The HPLC fingerprint was ob-tained with Thermo Hypersil Gold C18(250 mm×4.6 mm,5μm)column and a gradient elution with the mobile phase consisting of ace-tonitrile(A)-0.2%acetic acid(B)at a flow rate of 1.0 ml/min. And the detection wavelength was set at 294 nm. Results The opti-mized extraction solvent of Dianbaizhu was the 30%ethanol and the optimized elution solvent of ARF enriched by AB-8 macroporous resins was the 35%ethanol. The methodological study on similarity and RSD in ARF HPLC fingerprint of three batches of samples cor-responded to related regulations. Conclusion The extraction and enrichment process of ARF is stable and repeatable.

OBJECTIVE:
To investigate the risk factors for cow's milk protein allergy (CMPA) among infants through a multicenter clinical study.
METHODS:
A total of 1 829 infants, aged 1-12 months, who attended the outpatient service of the pediatric department in six hospitals in Shenzhen, China from June 2016 to May 2017 were enrolled as subjects. A questionnaire survey was performed to screen out suspected cases of CMPA. Food avoidance and oral food challenge tests were used to make a confirmed diagnosis of CMPA CMPA. A multivariate logistic regression analysis was used to investigate the risk factors for CMPA.
RESULTS:
Among the 1 829 infants, 82 (4.48%) were diagnosed with CMPA. The multivariate logistic regression analysis showed that maternal food allergy (OR=4.91, 95%CI: 2.24-10.76, P<0.05), antibiotic exposure during pregnancy (OR=3.18, 95%CI: 1.32-7.65, P<0.05), and the introduction of complementary food at an age of <4 months (OR=3.55, 95%CI: 1.52-8.27, P<0.05) were risk factors for CMPA, while exclusive breastfeeding (OR=0.21, 95%CI: 0.08-0.58, P<0.05) and the introduction of complementary food at an age of >6 months (OR=0.38, 95%CI: 0.17-0.86, P<0.05) were protective factors.
CONCLUSIONS
The introduction of complementary food at an age of <4 months, maternal food allergy, and antibiotic exposure during pregnancy are risk factors for CMPA in infants.

OBJECTIVE:
To observe the tubulointerstitial damage (TID) in lupus nephritis (LN) and investigate the relationship between autoantibodies and TID in lupus nephritis.
METHODS:
This cross-sectional study was conducted in a comprehensive tertiary hospital in Peking University Shenzhen Hospital. From March 2012 to July 2021, LN patients who performed renal biopsy were enrolled in the study. Clinical, laboratory and pathology data were collected. We classified the patients into none-or-mild group and moderate-to-severe groups according to the severity of interstitial fibrosis (IF) /tubular atrophy (TA) or tubulointerstitial inflammation (TII). The t test, U test and Chi-square test were used for statistical analysis as appropriate.
RESULTS:
A total of 226 patients were included, of who 190 (84%) were female with a median age of 32 (26, 39) years. 89% (201/226) of the patients who pathologically proved to be proliferative LN by renal biopsy. The frequency of moderate-to-severe TII and moderate-to-severe IF/TA was 30% (67/226) and 34% (76/226) respectively. For autoantibodies, the patients with moderate-to-severe TII had a lower rate of positive serum anti-ribonucleoprotein (anti-RNP) antibodies than the patients with none-or-mild TII (34% vs. 51%), and moderate-to-severe IF/TA had a lower rate of positive anti-ribosomal P protein (anti-P) antibodies than patients with none-or-mild IF/TA (19% vs. 33%). For other clinical indicators, the patients with moderate-to-severe TII and moderate-to-severe IF/TA were more often combined with proliferative LN, hypertension and anemia than the patients with none-or-mild TII and none-or-mild IF/TA, respectively. The patients with moderate-to-severe TII had higher serum creatinine values and lower glomerular filtration rates than the patients with none-or-mild TII. The patients with moderate-to-severe IF/TA had higher serum creatinine values, and lower glomerular filtration rates than the patients with none-or-mild IF/TA.
CONCLUSION
In patients with LN in Southern China, anti-RNP antibodies and anti-P antibodies may be potential protective factors for TII and IF/TA, respectively. More studies are needed to identify the risk factors of lupus patients with TID and investigate the correlation between autoantibodies and TID, which are critical for developing better preventive and therapeutic strategies to improve the survival rate of LN.

Objective: To analyze the clinical characteristics of children with multisystem inflammatory syndrome (MIS-C) associated with SARS-CoV-2 in China, and to improve the understanding of MIS-C among pediatricians. Methods: Case series study.Collect the clinical characteristics, auxiliary examinations, treatment decisions, and prognosis of 64 patients with MIS-C from 9 hospitals in China from December 2022 to June 2023. Results: Among the 64 MIS-C patients, 36 were boys and 28 were girls, with an onset age being 2.8 (0.3, 14.0) years. All patients suffered from fever, elevated inflammatory indicators, and multiple system involvement. Forty-three patients (67%) were involved in more than 3 systems simultaneously, including skin mucosa 60 cases (94%), blood system 52 cases (89%), circulatory system 54 cases (84%), digestive system 48 cases (75%), and nervous system 24 cases (37%). Common mucocutaneous lesions included rash 54 cases (84%) and conjunctival congestion and (or) lip flushing 45 cases (70%). Hematological abnormalities consisted of coagulation dysfunction 48 cases (75%), thrombocytopenia 9 cases (14%), and lymphopenia 8 cases (13%). Cardiovascular lesions mainly affected cardiac function, of which 11 patients (17%) were accompanied by hypotension or shock, and 7 patients (12%) had coronary artery dilatation.Thirty-six patients (56%) had gastrointestinal symptoms, 23 patients (36%) had neurological symptoms. Forty-five patients (70%) received the initial treatment of intravenous immunoglobulin in combination with glucocorticoids, 5 patients (8%) received the methylprednisolone pulse therapy and 2 patients (3%) treated with biological agents, 7 patients with coronary artery dilation all returned to normal within 6 months. Conclusions: MIS-C patients are mainly characterized by fever, high inflammatory response, and multiple organ damage. The preferred initial treatment is intravenous immunoglobulin combined with glucocorticoids. All patients have a good prognosis.
