This paper summarizes Professor Gao Jiansheng's clinical experience in treating herpes simplex keratitis （HSK） based on the theory of hidden pathogens. It is believed that the core pathogenesis of HSK involves deficiency of vital qi and the internal presence of pathogenic factors. In the early stage， the pathogenesis is characterized by lung and spleen qi deficiency and invasion of external pathogens. In the middle stage， pathogenesis worsens due to latent pathogens damaging the vital qi and spleen deficiency with dampness. In the late stage， kidney yang deficiency and lingering pathogenic toxins are the root cause of recurrent attacks. In clinical practice， it is recommended to strengthen and protect the vital qi. In the early stage， the Modified Yupingfeng Powder （玉屏风散） is used. In the middle stage， the Modified Linggui Zhugan Decoction （苓桂术甘汤） is used. In the late stage， a self-formulated Modified Bushen Tuodu Fomulation （补肾托毒方） is applied. Additionally， herbs of tonifying qi and strengthening the exterior are used throughout the treatment to reduce recurrence.

Benign essential blepharospasm(BEB)is a neurological disorder characterized by involuntary contractions of periocular muscles, which can lead to functional blindness and significantly impair patients' quality of life. This article systematically reviews the epidemiology, clinical manifestations, pathogenesis, and therapeutic advances in BEB. Epidemiological data indicate that the global prevalence of BEB is approximately 1 in 200000, with a predilection for individuals over 50 years of age and a significantly higher incidence in female than in male. The exact pathogenesis of BEB remains incompletely understood, though current evidence suggests close associations with neurotransmitter dysfunction, reduced cortical inhibition, and genetic susceptibility. Therapeutic strategies primarily focus on symptomatic management. Botulinum toxin type A(BTX-A)injection remains the first-line treatment but requires repeated administrations due to transient efficacy. Other treatments, including oral drugs, surgery, and repetitive transcranial magnetic stimulation, also have major limitations. By synthesizing recent research progress from domestic and international studies, this review aims to provide novel insights for the clinical management of BEB, ultimately improving patient outcomes.

Objective To observe the value of ultrasound assessment of diaphragm function combined with the Medical Research Council(MRC)muscle strength score and acute physiology and chronic health Ⅱ(APACHE Ⅱ)score for predicting weaning outcome in severe pneumonia patients after mechanical ventilation.Methods Totally 102 patients with severe pneumonia who underwent mechanical ventilation were retrospectively enrolled.Spontaneous breathing trial(SBT)was performed,and diaphragmatic mobility and contraction velocity were measured before and after SBT to evaluate diaphragm function.All patients were divided into successful weaning(successful group,n=76)and failed weaning group(failure group,n=26)according to breathing condition after weaning.Univariate analysis and multivariate logistic regression were used to analyze clinical data,MRC and APACHE Ⅱ scores before SBT,as well as diaphragm function parameters before and after SBT,and the independent risk factors for weaning failure were screened,based which a combined regression model was established.The diagnostic efficacy of each independent risk factor and combined regression model was evaluated by receiver operating characteristic curve and the area under the curve(AUC).Results MRC and APACHE Ⅱ scores,diaphragmatic mobility and contraction velocity before SBT were all independent risk factors for weaning failure in severe pneumonia patients after mechanical ventilation(all P＜0.05),with AUC of 0.682,0.667,0.785 and 0.685,respectively.The AUC of combined regression model established with the above independent risk factors was 0.898,higher than that of each independent risk factor(all P＜0.05).Conclusion Ultrasound assessment of diaphragm function combined with MRC muscle strength and APACHE Ⅱ scores could effectively predict weaning outcome in severe pneumonia patients who underwent mechanical ventilation.

Objective:To investigate the value of a 5-point predictive score based on unenhanced CT combined with blood glucose detection for predicting short-term prognosis in patients with spontaneous cerebral hemorrhage.Methods:A total of 102 patients with spontaneous intracerebral hemorrhage who received treatment in Zhejiang Provincial People's Hospital from March 2020 to March 2022 were included in this study and analyzed retrospectively. Blood glucose level was measured and BAT score was used to evaluate hematoma enlargement. After 30 days, Glasgow Outcome Scale was used to evaluate the prognosis of patients. The relationships between blood glucose and BAT score, and between blood glucose and BAT score and prognosis were analyzed. The value of blood glucose and BAT score for predicting short-term prognosis was analyzed.Results:The Glasgow Outcome Scale results showed that among the 102 patients, 24 patients (23.53%) had poor prognosis. The BAT score and blood glucose level in patients with poor prognosis were (3.13 ± 0.68) points and (11.58 ± 2.30) mmol/L, respectively, which were significantly higher than (2.40 ± 0.59) points and (8.88 ± 1.71) mmol/L in patients with good prognosis ( t = 5.10, 5.30, both P < 0.05). Pearson correlation analysis showed that in patients with spontaneous intracerebral hemorrhage, blood glucose level was positively correlated with BAT score ( r = 0.43, P < 0.05). Spearman correlation analysis showed that in patients with spontaneous intracerebral hemorrhage, blood glucose level and BAT level were positively correlated with prognosis ( r = 0.42, 0.47, both P < 0.05). The receiver operating characteristic curve showed that the area under the curve plotted for BAT score combined with blood glucose level for predicting short-term prognosis was 0.874, which was significantly greater than the area under the curve plotted for BAT score alone for predicting short-term prognosis ( Z = 2.54, P < 0.05). Conclusion:A large proportion of patients with spontaneous intracerebral hemorrhage have a poor prognosis. The patients with a poor prognosis have higher blood glucose levels and BAT scores than those with good prognosis. Blood glucose and BAT score have a high value for predicting the prognosis of patients with spontaneous intracerebral hemorrhage.

【Objective】 To clone the full-length of human kidney and brain protein (KIBRA) coding sequence in eukaryotic expression vector and provide a model for studying the biological function of KIBRA in breast cancer cells. 【Methods】 Total RNA of human breast cancer cell line MCF7 was extracted. After reverse transcription, the full length of KIBRA (NM_001161661.2) coding region was amplified by PCR, and cloned into eukaryotic expression vector pCMV-Blank. After identification, it was defined officially as pCMV-KIBRA. Then it was transfected into MCF7 cells, and the expression of KIBRA was detected by real-time PCR and Western blotting after 48 hours. The primary, secondary and tertiary structures and post-transcriptional modification sites of KIBRA were analyzed with bioinformatics software. 【Results】 Bacterial PCR, double enzyme digestion and DNA sequencing results showed that the correct sequence of KIBRA was inserted into the vector pCMV-KIBRA. The mRNA and protein expressions of KIBRA were significantly increased in MCF7 cells transfected with pCMV-KIBRA. Bioinformatics analysis showed that KIBRA was composed of 1119 amino acids. There were 52 phosphorylation sites, 1 acetylation site and 5 ubiquitination sites, and the protein structure was mainly α-helix and random coil. 【Conclusion】 The eukaryotic expression vector of full-length of human KIBRA coding sequence was successfully constructed and overexpressed in breast cancer cell line MCF7, which can lay a foundation for studying the biological function of KIBRA in breast cancer.

ObjectiveTo investigate the association of the expression of the NK cell-activating receptor NKG2D, its ligand major histocompatibility complex class I chain-related gene A (MICA), and related cytokines ［interferon-γ (IFN-γ), interleukin-10 (IL-10), and interleukin-15 (IL-15)］ with intrahepatic inflammation in primary biliary cholangitis (PBC). MethodsLiver biopsy specimens were collected from 30 patients with PBC (PBC group), 15 patients with chronic hepatitis B (CHB group), and 10 patients with nonalcoholic fatty liver disease (NAFLD group), who were hospitalized in The Second Affiliated Hospital of Kunming Medical University from August 2014 to June 2015. The degree of liver inflammation (G) and fibrosis degree (S) of the liver specimens were determined, and immunohistochemistry was used to measure the expression of NKG2D, MICA, IFN-γ, IL-10, and IL-15 in liver tissue (the scores were determined based on the number of cells stained and the degree of staining to evaluate the expression of each marker). A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the t-test was used for comparison between two groups; a Spearman correlation analysis was used to investigate correlation. ResultsIn the PBC group, the expression of NKG2D increased with the degree of inflammation, and the patients with G3-4 inflammation had significantly higher expression than those with G1-2 inflammation (G1 vs G2 vs G3 vs G4: 1.4±0.05 vs 1.56±0.05 vs 1.86±0.11 vs 2.60±0.17, F=150.8, P＜0.05); the expression of NKG2D decreased with fibrosis degree (S3 vs S4: 2.30±0.17 vs 1.56±0.05, t=-1.52, P＜0.05). In the PBC group, there was no significant difference in MICA between G3 and G4 (0.11±0.01 vs 0.20±0.03, t=-2.20, P＞0.05) and between S3 and S4 (0.12±0.02 vs 0.18±0.03, t=-2.64, P＞0.05). In the PBC group, there was a significant difference in the expression of IL-15 between the patients with different degrees of inflammation (G1 vs G2 vs G3 vs G4: 0.70±0.10 vs 1.50±0.10 vs 1.93±0.11 vs 2.60±0.17, F=251.3, P＜0.05), while there was no significant difference between the patients with different fibrosis degrees (S3 vs S4: 2.00±0.05 vs 2.40±0.30, t=-1.62, P＞0.05). In the CHB group, there was a significant difference in the expression of IL-15 between the patients with different degrees of inflammation (G1 vs G2 vs G3: 0.73±0.15 vs 1.96±0.15 vs 2.50±0.17, F=150, P＜0.05) and between the patients with different fibrosis degrees (S1 vs S2 vs S3: 0.70±0.10 vs 21.96±0.15 vs 2.50±0.17, F=158.7, P＜0.05). In the PBC group, the expression of IL-10 was only observed in the patients with G1 inflammation (0.16±0.01), and in the CHB group, the expression of IL-10 was observed in the patients with G1 and G2 inflammation, with no significant difference (G1 vs G2: 0.19±0.01 vs 0.13±0.01, t=-1.522, P＞0.05). In the patients with PBC, the expression of IL-15 in liver tissue was positively correlated with the levels of alkaline phosphatase (ALP) and gamma-glutamyl transpeptidase (GGT) (r=0.241 and 0.407, P=0.014 and 0.045). ConclusionThe NK cell-activating receptor NKG2D affects the degree of intrahepatic inflammation in PBC, and the NKG2D ligand MICA is expressed in the advanced stage of PBC and can downregulate NKG2D. The expression of IL-15 increases with the degree of inflammation in PBC and is positively correlated with the levels of ALP and GGT, suggesting that the activation of NK cells and abnormal secretion of cytokines are involved in the development and progression of PBC and IL-15 may be used as an auxiliary index for the diagnosis of PBC.

Objective To evaluate the immunogenicity and safety of inactivated poliovirus vaccine derived from Sabin strain (sIPV) in Banna mini pigs, and to provide experimental evidence for the new animal model. Methods sIPV vaccines which are listed at Institute of Medical Biology at Chinese Academy of Medical Sciences were used in this study. The groups of intramuscular sIPV and the wild strain IPV injections (IPV derived from wild strain, wIPV) were designed, and the saline group was used as a negative control group. The Banna mini pigs in various groups were immunized at 0, 1 and 2 months. Blood samples were collected before immunization and on days 30 after each immunization. Levels of neutralizing antibodies were tested for evaluating immunogenicity. The safety was evaluated by observation of the status and weight of mini pigs. Results After the three dose immunization schedules in the Banna mini pigs, the seroconversion rates of type Ⅰ,Ⅱ and Ⅲ sIPV experimental groups and wIPV group were all up to 100%. The neutralizing antibody levels in all the three types were much higher than the protective titer 1: 8. The weight of mini pigs increased after vaccination. Conclusions The sIPV vaccine has good immunogenicity and safety in Banna mini pigs. Banna mini pigs could be a new animal model for evaluation of sIPV vaccine.

ObjectiveTo investigate the effects of maternal thyroid dysfunction during pregnancy caused by iodine deficiency of different degrees on doublecortin ( DCX ) and synaptophysin ( p38 ) expressions in fetal brain.Methods Wistar female rats were randomly divided into four groups:adequate iodine ( AI),mild iodine deficiency ( MiID ),moderate iodine deficiency ( MoID ),and severe iodine deficiency ( SID ),according to the total daily iodine supply( fed on an iodine deficient diet with different dosages of KI added in drinking water).Three months later the rats were mated.Serum TSH and thyroid hormones were determined in maternal rats on gestational day 20 using chemiluminescent immunoassay.The iodine contents in urine and histological changes of thyroid gland were observed in pregnant rats.The mRNA and protein levels of DCX and synaptophysin ( p38 ) were analyzed in fetal brain by using real time quantitative RT-PCR and western blotting respectively.Results( 1 ) Iodine contents in urine of pregnant rats were reduced with the decrease of their iodine supply.Compared with group AI,serum TSH was significantly increased [ ( 2.95 ± 1.70 vs 1.31 ± 0.55 ) mU/L,P ＜ 0.05 ],and both TT4 and FT4 were significantly decreased [ ( 14.3±4.1 vs 28.4±19.3 ) nmol/L,P＜0.05 ] and [ ( 10.8±3.6 vs 20.2±8.0) pmol/L,P＜0.01 ] in pregnant rats of SID group.Whereas,a slight rise in TSH,and a mild decline in both TT4and FT4 were found in MoID and MiID groups.However,there were no significant changes in TT3 and FT3 levels among these four groups.( 2 )Histological characteristics of thyroid gland in pregnant rats showed a typical goiter with small follicular hyperplasia and lack of colloid in SID group,moderate follicular hyperplasia with decreased colloid in MoID group; but mild cellular hyperplasia without decrease in follicular size and colloid in MiID group.( 3 ) The mRNA levels of DCX were increased in fetal brains of three iodine deficiency groups compared with AI group,but a statistical significance was found in MoID group.The protein levels of DCX in all experiment groups were significantly increased.Both mRNA and protein expressions of synaptophysin ( p38 )were significantly down-regulated in three iodine deficiency groups.Conclusions Maternal thyroid dysfunction caused by iodine deficiency,even by mild or moderate iodine deficiency,may lead to retardation of fetal neuronal and synaptic growth.
