Heart failure （HF） is the end stage of various cardiovascular diseases， manifested as ventricular filling or impaired left ventricular ejection fraction （LVEF）. Type 2 diabetes mellitus （T2DM） is a metabolic disorder， mainly caused by insufficient insulin secretion and insulin resistance. The incidence rates of the two common clinical diseases are increasing year by year. HF and T2DM are mutually causal chronic diseases， and their mutual deterioration can form a HF-T2DM comorbidity. The comorbidity status significantly increases the mortality and readmission risk of patients， and seriously affects the quality of life of patients. At present， western medicine treatment mainly involves the use of anti HF drugs and hypoglycemic drugs， which can significantly alleviate the clinical symptoms of patients. However， these two categories of drugs are numerous in variety and differ in their mechanisms， and blind combination may produce adverse reactions. With its unique theoretical system， traditional Chinese medicine exhibits the advantages of multiple components， multiple targets， and high safety through traditional Chinese medicine monomers， Chinese patent medicine， traditional Chinese medicine compounds， and acupuncture， which significantly delays the development of HF-T2DM and shows great potential in clinical treatment. A large number of clinical studies have shown that the integrated traditional Chinese and western medicine in the treatment of HF-T2DM has a significant effect in improving cardiac function， controlling blood glucose levels， and improving the quality of life of patients. Based on relevant research at home and abroad， this paper reviewed the HF-T2DM pathogenesis， pharmacological effects， research status of traditional Chinese and western medicine， and early prevention strategies， and discussed current problems and future research directions， in order to provide new ideas and useful references for clinical prevention and treatment of HF-T2DM.

ObjectiveTo explore the target of Erzhiwan in reducing myocardial injury in ovariectomized mice through non-targeted myocardial metabolomics combined with experimental verification. MethodsOvariectomized mouse model was selected， 40 female C57BL/6 mice were randomly divided into sham operation group， model group， estrogen group（estradiol valerate， 1.3×10^-4 g·kg^-1）， Erzhiwan low and high dose groups（3.12， 9.36 g·kg^-1）， with 8 mice in each group. Each administration group was given the corresponding dose of Erzhiwan by gavage， and the sham operation group and model group were given equal volume of distilled water by gavage for 12 weeks. Echocardiography was used to detect cardiac function， hematoxylin-eosin（HE） staining was used to observe myocardial morphological changes， and enzyme-linked immunosorbent assay（ELISA） was used to detect the levels of estrogen， N-terminal pro-brain natriuretic peptide（NT-proBNP）， hypersensitive troponin T（hs-TnT）， total cholesterol（TC）， triglyceride（TG）， low density lipoprotein cholesterol（LDL-C）， high density lipoprotein cholesterol（HDL-C）， interleukin（IL）-1β， IL-18 and tumor necrosis factor-α（TNF-α）. The non-targeted metabolomics of mouse myocardium were analyzed by ultra performance liquid chromatography-quadrupole-electrostatic field orbital trap high-resolution mass spectrometry（UPLC-Q-Exactive Orbitrap MS）， and the differential metabolites and corresponding metabolic pathways were obtained. The mRNA expression levels of phosphatidylinositol 3-kinase（PI3K） and protein kinase B（Akt） in mouse myocardial tissues were detected by real-time fluorescence quantitative polymerase chain reaction（Real-time PCR）， and the protein expression levels of PI3K， Akt， phosphorylated（p）-Akt were detected by Western blot. ResultsCompared with the sham operation group， the model group showed abnormal cardiac function， increased myocardial fiber space， cardiomyocyte atrophy， sarcoplasmic aggregation， and occasional dissolution or rupture of muscle fiber， the level of estrogen in the serum was decreased， the levels of NT-proBNP， hs-TnT， IL-1β， IL-18， TNF-α， TG， TC and LDL-C were increased， and the level of HDL-C was decreased（P<0.01）. Compared with the model group， Erzhiwan could increase the level of estrogen， improve the abnormal cardiac function， reduce the pathological injury of myocardial tissue， decrease the levels of myocardial injury markers（NT-proBNP， hs-TnT） and inflammatory factors（IL-1β， IL-18， TNF-α）， decrease the levels of TG， TC， LDL-C， and increased the level of HDL-C（P<0.01）. The results of non-targeted myocardial metabolomics showed that 31 of the 162 differential metabolites between the model group and sham operation group were significantly adjusted after administration of Erzhiwan， which were mainly glycerol phospholipid metabolites. Pathway enrichment results showed that Erzhiwan mainly affected glycerophospholipid metabolic pathway， PI3K-Akt pathway， cyclic guanosine monophosphate（cGMP）-protein kinase G（PKG） pathway and other metabolic pathways. Compared with the sham operation group， the levels of phosphatidylcholine（PC， 11 types） and phosphatidylethanolamine（PE， 5 types） in mouse myocardial tissue of the model group were increased（P<0.05， P<0.01）， and the mRNA and protein expressions of PI3K and p-Akt were decreased（P<0.05， P<0.01）. Compared with the model group， the levels of PC（11 types） and PE（5 types） were decreased（P<0.05， P<0.01） in myocardial tissue of Erzhiwan group， the mRNA and protein expressions of PI3K and p-Akt were elevated（P<0.01）. ConclusionErzhiwan can alleviate the pathological injury of myocardium in ovariectomized mice， improve the abnormal cardiac function， improve lipid metabolism disorder， and reduce the levels of myocardial injury markers and inflammatory factors， which involves a number of signaling and metabolic pathways in the heart， among which glycerophospholipid metabolism pathway and PI3K/Akt pathway may have key roles.

Objective To investigate the ocular biological parameters of children with idiopathic short stature(ISS)and compare them with those of children with growth hormone deficiency(GHD)and normal children,and to explore the characteristics of ocular biological parameters in this group,so as to provide a reference for the screening of visual acuity and the safety of growth hormone therapy in children with ISS.Methods A total of 15 children aged 5-14 years old with ISS were selected as the observation group,32 children with GHD were selected as the control group,and 47 children of normal height who underwent routine visual acuity screening were selected as normal controls.The ocular biological parameters of children with ISS were studied.The differences of vision-re-lated parameters between the above three groups were compared.The influencing factors affecting the visual devel-opment of children with ISS were analyzed.Results The axial ratio of ISS was significantly higher than that of the GHD group and normal children,and the intraocular pressure of the ISS group was significantly higher than that of the GHD group and normal children.There was no significant difference in axial length between the ISS group and the GHD group,as well as normal children(P＞0.05),but the axial length of the GHD group was significantly shorter than that of normal children.The corneal curvature of ISS was significantly greater than that of normal chil-dren.The axial rate ratio of the ISS group was positively correlated with the peak value and corneal curvature of growth hormone provocation test(β=1.052,P＜0.05;β=0.004,P＜0.05).Conclusion Children with ISS may have high intraocular pressure and high risk of myopia.Higher peak results of growth hormone provocation test and large corneal curvature may be the risk factors for myopia.

Objective: To evaluate the effect of inactivated SARS-CoV-2 vaccine on the clinical outcomes of patients infected with the Omicron variant. Methods: A total of 1 403 Omicron-infected patients admitted to 20 designated hospitals in Guangdong Province from January 1 to May 31, 2022, were selected as subjects in this study. A case-control study was conducted to collect the demographic data, underlying disease, vaccination status, last exposure date, gene sequencing of infected strains and clinical outcomes from the China Disease Prevention and Control Information System and Guangdong telemedicine platform. Pneumonia (common, severe and critical) and non-pneumonia (asymptomatic and mild) were selected as the case group and control group. The effect of inactivated SARS-CoV-2 vaccine on the clinical outcomes of patients infected with the Omicron variant was analyzed. Results: The median age [M (Q₁, Q₃)] of the subjects was 36 (27-47) years old, with males accounting for 52.25% (733 cases). The main outcome of the infection was non-pneumonia, accounting for 92.09% (1 292 cases), and the duration [M (Q₁, Q₃)] of the disease was 18 (14-22) days. There were 134 (9.55%), 39 (2.78%), 403 (28.72%), 437 (31.15%) and 390 (27.80%) cases with no or partial vaccination, within 90 days of primary vaccination, over 90 days of primary vaccination, within 90 days of booster vaccination and over 90 days of booster vaccination, respectively. Multivariate logistic regression analysis showed that after adjusting for gender, age, underlying disease, and location of the report, compared with those with no or partial vaccination, the risk of developing pneumonia was lower in those with over 90 days of primary vaccination, within 90 days of booster vaccination and over 90 days of booster vaccination [OR (95%CI) values were 0.52 (0.28-0.98), 0.39 (0.21-0.73) and 0.40 (0.21-0.77), respectively]. Cox proportional hazard regression model analysis showed that after adjusting for gender, age, underlying disease and location of the report, the duration of the disease was shorter in those who received booster vaccinated for more than 90 days compared with that in those who had no or partial vaccination [HR (95%CI): 1.26 (1.03-1.55)]. Conclusion: The inactivated SARS-CoV-2 vaccine affects the clinical outcomes of patients infected with the Omicron variant.

Objective : To study the correlation between short stature and ocular biological parameters in children. Methods : This study adopted a cross⁃sectional study. Eighty⁃two children (82 eyes) with height lower than the tenth percentage and normal vision were selected as the short group. One hundred and thirty healthy children ( 130 eyes) with age and sex matching were served as the control group. Ocular biological parameters were measured for all subjects , including visual acuity , axial length , corneal curvature , astigmatism , intraocular pressure , central corneal thickness , anterior chamber depth , lens thickness and the distance of whiteness to whiteness. Then axial length/corneal radius ratio was calculated. The differences in ocular biological parameters between the two groups and the correlation between height and parameters were analyzed. Results: The measurement of ocular biological parameters showed that the axial length of the short group was lower than that of the control group , and the difference was statistically significant( t = - 3. 161 ,P = 0. 002) . Also there were significant differences in corneal curvature , anterior chamber depth between the two groups ( t = 2. 996 , - 2. 449, P < 0. 05) . The corneal curvature of the short group was greater than that of the control group , and the anterior chamber depth of the short group was smaller than that of the control group. There were no significant differences in other ocular biological parameters ( P >0. 05) . Conclusion There are differences between ocular biological parameters in short children and healthy children ,which suggests that on the one hand , parents should pay attention to the development of the eyes of their children as soon as possible ; On the other hand , there should be different screening standards for short children in eye screening. Moreover, more comprehensive studies need to be included to supplement this data in the future.

Objective To investigate the indications of optic canal decompression in the patients with front-orbital fibrous dysplasia and the methods of intraoperative optic canal localization and decompression. Methods We collected 30 cases of fibrous dysplasia. All patients had sufficient images assessment. Patients with symptoms underwent surgery, including front-orbital cranioplasty and optic canal decompression. The frontotemporal epidural approaches were used. If there was a proptosis, the approach was extended with the removal of superior orbital ridge. Six patients undertook intraoperative CT and MRI fusion navigation, assisting in confirming the trunk, orbital and cranial orifice of optic nerve. During the operation, the optic canals were decompressed by three-bits method, to confirm the position of optic nerve. Results There were 30 cases of optic canal decompression and one case of vision loss. The visual acuity and vision field of the remaining patients improved to varying degrees. The proptosis disappeared or alleviated after the operation. Thirteen cases were reconstructed with normal internal plate, five cases with titanium plate, nine cases without reconstruction, and two cases were paved with proliferative broken bone on the orbital top; one case recurred with exophthalmos again after five years, but the visual acuity did not decline. Conclusion For the patients with front-orbital fibrous dysplasia, active surgical treatment should be taken, optic canal decompression should be chosen for diminution of vision, craniofacial anaplasty and orbital decompression should be performed in patients with facial deformity. The epidural approach is a good option to locate the optic nerve from the orbital orifice or cranial orifice. Combined with the three-bits method, we can achieve safe and meticulous optic nerve decompression.

Aim To investigate the effect of curcumin against high-fat-diet induced C57BL/6J mice bone changes and the correlation between the expression of cathepsin K and curcumin.Methods Curcumin treated C57BL/6J mice had been on high fat diet for 12 weeks.The HE, Alizarin red S staining and Safranin O/fast green staining of femur were employed to evaluate bone microstructure, bone metabolism and bone development.The expressions of cathepsin K were assessed by Western blot and immunohistochemical staining.Results Histopathological results showed that curcumin could improve the destruction of trabecular bone structure, cartilage development and bone calcification.Biomechanical results proved that curcumin could improve the bone strength of the type 2 diabetic mice induced by high fat.The results of immunohistochemistry and Western blot assay indicated that curcumin could significantly inhibit the expression of cathepsin K in bone tissues of mice.Conclusion Curcumin can increase bone strength, improve bone microstructure, and enhance the degree of bone calcification, which may be achieved by inhibiting the expression of cathepsin K.

Objective To study the CT and MRI imaging features of central nervous system Rosai-Dorfman disease and to enhance knowledge and differential diagnostic ability for central nervous system Rosai-Dorfman disease.Methods The CT and MRI imaging appearances in 4 cases of pathologically proven Rosai-Dorfman disease were retrospectively evaluated and the literature of central nervous system Rosai-Dorfman disease were reviewed.Results Two cases had cranial CT scans,4 cases had cranial MRI scans,On CT scans,cerebral edema was demonstrated in one case and the other case was normaL MRI scans showed the lesions were solitary in saddle area in 3 cases,and multiple in anterior cranial fossa in 1 case.The lesions exhibited iso- to hypointensity on both T1WI and T2WI images.Following intravenous injection of contrast medium,ring-like enhancement was seen in 2 cases and homogeneous enhancement in 1 case.Nodular enhancement was seen in the case of multiple lesions in the anterior cranial fosse.All lesions were dural-based.Conclusions In patients with fever,headache,elevation of the erythrocyte sedimentation rate (ESR) and a polyclonal increase in .γ-globulins,the possibility of central nervous system Rosai-Dorfman disease should be considered when single or multiple dural-based mass lesions,especially in sellar region,were identified by CT and MRI.
