Results Glaucoma occurred in 9 eyes(26%),in which silicone oil glaucoma(SOG)accounted for 77%(7/9).The changes of the superior part of anterior chamber angle were peripheral anterior synechiae in 11 eye(32%) and SO emulsification droplets in 22 eyes(64%) in 1～4.5 months after surgeries.Glaucoma occurred in 6 eyes of 7 eyes undergone peripheral iridectomy at the inferior part of the iris after the closure of iridectomy holes(P

Objective To explore the value of ultrasound elastography in the non-invasive monitoring of liver elasticity of stable recipients at different stages after liver transplantation. Methods Clinical data of 73 stable recipients after liver transplantation were collected. According to the time after liver transplantation, all patients were divided into the early group (n=25) and medium-to-long group (n=48). In addition, 38 healthy subjects were assigned into the control group. The ultrasound indexes and liver function indexes were statistically compared among each group. The ultrasound elastography indexes of liver and spleen were analyzed, and their correlation with liver function indexes was analyzed. Results Compared with the control group, the ultrasound indexes, alanine aminotransferase (ALT), γ-glutamyl transferase (GGT) and alkaline phosphatase (ALP) levels were significantly increased in the early group (all P < 0.05), and the ultrasound indexes in the medium-to-long group were significantly increased, whereas the GGT level was significantly decreased (all P < 0.05). Compared with the early group, the right oblique diameter of liver, ALT, GGT and ALP levels were significantly decreased in the medium-to-long group (all P < 0.05). Compared with the control group, the sound touch elastography (STE) and sound touch quantify (STQ) values of liver and STE value of spleen in the early group and medium-to-long group were significantly increased (all P < 0.05). Compared with the early group, the ultrasound elastography indexes of liver and spleen in the medium-to-long group were remarkably decreased (all P < 0.05). The ultrasound elastography indexes of liver were weakly correlated with the ALT, aspartate aminotransferase (AST) and GGT levels, significantly correlated with ALP level. The STE value of spleen was weakly correlated with the ALP level. The STE value of liver was significantly correlated with the STQ value of liver. The STE and STQ values of liver were weakly correlated with the STE value of spleen. Conclusions The characteristics of liver elasticity in stable recipients after liver transplantation are various among different stages. Persistent monitoring of liver elasticity may provide a novelnon-invasive monitoring method during follow-up after liver transplantation.

Objective:To analyze measurement results of serum allergen-specific immunoglobulin E (IgE) in patients with eczema/dermatitis.Methods:A retrospective analysis was conducted on serum allergen-specific immunoglobulin E (IgE) levels in 3 051 patients with eczema/dermatitis, who visited the allergy clinic of Huashan Hospital from April 1, 2021 to March 31, 2022. The serum allergen-specific IgE level was detected by using the Phadia allergen detection system, and positive rates of allergens were calculated to determine common inhaled allergens and food allergens in patients with eczema/dermatitis. Comparisons of enumeration data between groups were performed by chi-square test.Results:Among the 3 051 patients with eczema/dermatitis, there were 1 412 with atopic dermatitis and 1 639 were other eczema/dermatitis. Detection of serum allergen-specific IgE showed that 1 629 (53%) patients were positive for allergens, and the number of positive allergen-specific IgEs in each patient was 3.0 ± 1.6. The top 3 common inhaled allergens in patients with eczema/dermatitis were Dermatophagoides farinae (904/1 522, 59%) , Dermatophagoides pteronyssinus (891/1 513, 59%) and Alternaria alternata (206/1 068, 19%) , and the top 3 common food allergens were shrimps (251/1 432, 18%) , egg white (165/992, 17%) and cow milk (149/994, 15%) . Among the 3 051 patients, 25 (1%) were aged < 2 years, 571 (19%) aged 2 - 12 years, 285 (9%) aged 12 - 18 years, and 2 170 (71%) were aged > 18 years. The most common food allergens were both egg white in the age groups of < 2 years and 2 -12 years (77%, 37%, respectively) , and were both shrimps in the age groups of 12 - 18 years and > 18 years (31%, 17%, respectively) . Dermatophagoides pteronyssinus and Dermatophagoides farina were the top 2 common inhaled allergens in all age groups, with the positive rate ranging from 36% to 84%; in addition, the positive rate of molds was relatively high in the age group of 2 - 12 years (mold mixture: 37%; Alternaria alternata: 27%) . From April 2021 to March 2022, the positive rate of outdoor allergens ranged from 10% to 15% among outpatients in every month; the positive rates of tree pollen and grass pollen increased from April 2021, and peaked in October 2021. The patients with atopic dermatitis showed a significantly increased positive rate of allergens (73%) compared with those with other eczema/dermatitis (37%, χ2 = 389.36, P<0.001) , and the rank of common allergens in the patients with atopic dermatitis was basically the same as that in those with eczema/dermatitis. Conclusions:The common allergens were Dermatophagoides farina, Dermatophagoides pteronyssinus and Alternaria alternata in the patients with eczema/dermatitis. Food allergy was more common in infant patients, and inhalation allergy was more common in child, adolescent and adult patients. The positive rate of allergen-specific IgEs was markedly higher in the patients with atopic dermatitis than in those with other eczema/dermatitis.

ObjectiveTo explore the mechanism of Tibetan medicine Ershiwuwei Guijiuwan against osteoporosis in ovariectomized rats through the classical Wnt/β-catenin signaling pathway. MethodForty-eight 3-month-old SD female rats were randomized into model group （equivalent volume of normal saline）， sham operation group （equivalent volume of normal saline）， estradiol group （0.1 mg·kg^-1 estradiol valerate）， and high-， medium-， low-dose Ershiwuwei Guijiuwan groups （800， 400， 200 mg·kg^-1， respectively）. For the modeling， some adipose tissue near the ovaries was removed in the sham operation group， and ovaries were excised in other groups. Administration （ig， once a day） started two weeks after the operation and lasted 12 weeks. After sampling， based on hematoxylin and eosin （HE） staining， the morphological changes of the right femur and lumbar spine of the rats were observed. The enzyme-linked immunosorbent assay （ELISA） was performed to detect the serum levels of rat tartrate-resistant acid phosphatase 5b （TRAP5b）， collagen type Ⅰ C-terminal peptide （CTX-Ⅰ）， bone alkaline phosphatase （BALP）， amino-terminal propeptide of type Ⅰ procollagen （PINP）， and bone Gla-protein （BGP）. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was performed to examine the mRNA expression of β-catenin and Runt-related transcription factor 2 （Runx2） in femur， and Western blot to detect the protein expression of β-catenin， Runx2， and low-density lipoprotein receptor-related protein-5 （Lrp-5）. ResultCompared with the sham operation group， the model group showed disordered and sparse bone trabecula with fewer connections， decrease in serum levels of BALP， BGP， and PINP （P<0.01）， increase in levels of CTX-Ⅰ and TRAP5b （P<0.01）， reduction in mRNA expression of β-catenin and Runx2 in femoral tissue （P<0.01） and protein expression of Lrp-5， β-catenin， and Runx2 （P<0.01）. Compared with the model group， estradiol and each dose of Ershiwuwei Guijiuwan increased the volume of bone trabecula， made thebone trabecula closely arranged， reduced the loss of the trabecular meshwork， raised the serum levels of BALP and BGP （P<0.01）， and lowered TRAP5b level （P<0.01）. PINP level was significantly increased in the high-dose Ershiwuwei Guijiuwan group and estradiol group （P<0.01） and CTX-Ⅰ level was significantly decreased in the high-dose Erwenwuwei Guijiuwan group and the estradiol group （P<0.01） compared with those in the model group. The mRNA expression of β-catenin in femoral tissue and protein expression of Lrp-5 and β-catenin in estradiol group and three Ershiwuwei Guijiuwan groups were significantly increased （P<0.05， P<0.01）， and the levels of Runx2 mRNA and protein were significantly increased in the high-dose Ershiwuwei Guijiuwan group and the estradiol group （P<0.01） compared with those in the model group. ConclusionTibetan medicine Ershiwuwei Guijiuwan is effective for the osteoporosis in ovariectomized rats， which may be related to the classic Wnt/β-catenin signaling pathway. It affects bone metabolism by up-regulating the expression of osteogenesis-related genes in the signaling pathway.

Cell pyroptosis is a programmed death of inflammatory cells. Many members of the gasdermin family （the effector protein family that forms pores） participate in the pathological process of a variety of diseases， such as cancer， myocardial ischemia， renal injury， and osteoarthritis， mainly by activating cysteine aspartate-specific protease （Caspase） for polymerization and shear. Cell pyroptosis has bidirectional regulation. Induction of pyroptosis can promote cell clearance under pathological conditions （such as cancer and tumor cells）， but long-term induction of pyroptosis can lead to abnormal lipid and related vitamin metabolism in vivo. Regulating the balance between cell pyroptosis and proliferation is an important target for traditional Chinese medicine （TCM） treatment of diseases. The Yin-Yang theory runs through the whole process of TCM diagnosis and treatment， which is used to explain the physiological and pathological changes of human body and guide the theory， diagnosis and treatment of diseases and health care. The balance between cell proliferation and pyroptosis is essentially the embodiment of Yin-Yang balance at the cellular level， and the theory of Yin-Yang spontaneous harmonization dominates the balance. TCM intervention on cell pyroptosis is mainly reflected in promoting and inhibiting cell pyroptosis， which has the same significance as Yin-Yang regulation. Based on this theory， this paper revealed the relationship between TCM inhibiting and promoting cell pyroptosis through the Yin-Yang theory， to provide theoretical support for the modernization of the Yin-Yang theory and new goals for the diagnosis and treatment of diseases.

Objective:To investigate the clinical characteristics of children with invasive pneumococcal di-sease (IPD) and the sensitivity of Streptococcus pneumoniae (SP) isolates to antibacterial drugs, so as to provide the reference for diagnosis and treatment of IPD. Methods:The clinical data of IPD patients in the Children′s Hospital of Chongqing Medical University from January 2014 to December 2018 as well as the drug sensitivity results of SP isolates were retrospectively analyzed.Results:The male to female ratio of 139 patients enrolled was 1.5∶1.0.One hundred and sixteen (83.5%) patients were under 5 years old.Of the 31 patients (22.3%) with underlying diseases, 7 patients (5.1%) had hematological malignancy, 6 patients (4.3%) had congenital heart diseases, and 18 patients (12.9%) were immunosuppressed.The common sources of infection were the respiratory system (59.0%, 82/139 cases) and the central nervous system (28.8%, 40/139 cases). The in-hospital mortality rate among them was 15.8% (22/139 cases). More than 90.0% of the SP isolates were insusceptible to Erythromycin, Tetracycline and Clindamycin, and 74.8% (104/139 cases) of the isolates were insusceptible to Meropenem.The susceptibility rate of SP isolates to Amoxicillin was 69.1% (96/139 cases). The SP isolates were completely susceptible to Vancomycin, Linezolid, Moxifloxacin and Ofloxacin.Meningitis isolates had lower susceptibility rates to Penicillin (10.0% vs. 54.5%, P<0.001) and Cefotaxime (32.5% vs. 74.7%, P<0.001) than those in nonmeningitis isolates. Conclusions:Children under 5 years old with underlying diseases are susceptible to IPD and have a high mortality rate.The SP isolates in children with IPD are highly insusceptible to Erythromycin, Tetracycline, Clindamycin and Meropenem, and completely susceptible to Vancomycin, Linezolid, Moxifloxacin and Ofloxacin.Meningitis isolates are less susceptible to Penicillin and Cefotaxime than non-meningitis isolates.

Ischemic stroke is a severe disorder resulting from acute cerebral thrombosis. Here we demonstrated that post-ischemic treatment with ciclopirox olamine (CPX), a potent antifungal clinical drug, alleviated brain infarction, neurological deficits and brain edema in a classic rat model of ischemic stroke. Single dose post-ischemic administration of CPX provided a long-lasting neuroprotective effect, which can be further enhanced by multiple doses administration of CPX. CPX also effectively reversed ischemia-induced neuronal loss, glial activation as well as blood-brain barrier (BBB) damage. Employing quantitative phosphoproteomic analysis, 130 phosphosites in 122 proteins were identified to be significantly regulated by CPX treatment in oxygen glucose deprivation (OGD)-exposed SH-SY5Y cells, which revealed that phosphokinases and cell cycle-related phosphoproteins were largely influenced. Subsequently, we demonstrated that CPX markedly enhanced the AKT (protein kinase B, PKB/AKT) and GSK3 (glycogen synthase kinase 3) phosphorylation in OGD-exposed SH-SY5Y cells, and regulated the cell cycle progression and nitric oxide (NO) release in lipopolysaccharide (LPS)-induced BV-2 cells, which may contribute to its ameliorative effects against ischemia-associated neuronal death and microglial inflammation. Our study suggests that CPX could be a promising compound to reduce multiple ischemic injuries; however, further studies will be needed to clarify the molecular mechanisms involved.
