Abstract
We report a fatal case of disseminated herpes zoster in a patient with multiple myeloma, illustrating the severe risks immunocompromised individuals face from viral infections. By combining a detailed case report with an extensive literature review, the paper seeks to shed light on the underlying susceptibility factors for varicella-zoster virus infection in multiple myeloma patients. We further evaluate effective prophylactic protocols for herpes zoster, aiming to equip clinicians with improved therapeutic strategies. The case underscores the critical need for vigilant clinical assessments and tailored patient management to mitigate infection risks and enhance patient outcomes.

Abstract
Adult-onset Still's disease (AOSD) is considered a rare autoimmune inflammatory disorder with an unclear etiology and pathogenesis.The main clinical manifestations of this disease are high fever, joint pain, and transient skin lesions. Physical examination may reveal hepatomegaly, splenomegaly, and lymphadenopathy, while laboratory tests show abnormalities such as elevated white blood cell count (WBC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and serum ferritin (SF). The lack of specific diagnostic markers contributes to a relatively high rate of clinical misdiagnosis and missed diagnoses.In terms of treatment, glucocorticoids have always been the cornerstone medication, but some patients exhibit suboptimal responses to conventional drug therapy, making disease control challenging. However, as our understanding of the pathogenesis continues to grow, novel therapeutic approaches targeting various cytokines have been gradually identified. In this report, we present a case of successful treatment of recurrent AOSD with tocilizumab (TCZ), along with a concise review of innovative treatment strategies for AOSD based on literature retrieval.

Abstract
BACKGROUND Melasma is a prevalent, persistent hyperpigmentation disorder that negatively affects the psychological health of patients. However, the treatment outcome remains unsatisfactory due to the complexity of pathogenesis, recurrence characteristics, and relatively high morbidity. OBJECTIVES To compare the performance of laser-related therapies in improving the melasma area severity index (MASI) score of melasma and the occurrence of adverse effects by network meta-analysis (NMA). METHODS From the inception to November 2022, eligible randomized controlled trials were identified. Two investigators independently searched relevant studies from PUBMED, EMBASE, and the Cochrane Library database. RESULTS A total of 39 clinical studies with 1394 participants were eligible for enrollment. For efficacy, the NMA demonstrated that Q-switched Nd: YAG laser + topical medications (QSND+TM) was superior to Q-switched Nd:YAG laser (QSND) [MD = -4.21 (-6.80, -1.63)], Er: YAG laser + topical medications (ERYL+TM) [MD = -3.52 (-6.84, -0.19)], and picosecond laser + topical medications (PICO+TM) [MD = -4.80 (-9.33, -0.27)]. The microneedling + topical medications (MN+TM) was superior to picosecond laser (PICO) [MD = -5.26 (-10.44, -0.08)] and topical medications (TM) [MD = -5.22 (-9.20, -1.23)]. The top five of the surface under the cumulative ranking curve value (SUCRA) are Q-switched Nd:YAG laser + topical medications (QSND+TM 85.9%), oral tranexamic acid (oTA 80.1%), microneedling + topical medications (MN+TM 79.7%), Q-switched Nd:YAG laser + intense pulse light (QSND+IPL 78.9%), and fractional carbon dioxide laser + topical medications (FCDL+TM 70.5%). CONCLUSIONS In conclusion, the Qs-Nd:YAG laser with topical medications is the first choice for treating melasma according to the SUCRA value. Among the three treatment modalities, namely MN + TM, PICO, and TM, our recommendation favors MN+TM as the superior choice for enhancing the curative efficacy in melasma. However, the actual clinical choice should also take into account the adverse effects, the skin type of the patient, the duration of the disease, and other relevant factors.

Abstract
Artificial Intelligence (AI) is progressively permeating medicine, notably in the realm of assisted diagnosis. However, the traditional unimodal AI models, reliant on large volumes of accurately labeled data and single data type usage, prove insufficient to assist dermatological diagnosis. Augmenting these models with text data from patient narratives, laboratory reports, and image data from skin lesions, dermoscopy, and pathologies could significantly enhance their diagnostic capacity. Large-scale pre-training multimodal models offer a promising solution, exploiting the burgeoning reservoir of clinical data and amalgamating various data types. This paper delves into unimodal models' methodologies, applications, and shortcomings while exploring how multimodal models can enhance accuracy and reliability. Furthermore, integrating cutting-edge technologies like federated learning and multi-party privacy computing with AI can substantially mitigate patient privacy concerns in dermatological datasets and further fosters a move towards high-precision self-diagnosis. Diagnostic systems underpinned by large-scale pre-training multimodal models can facilitate dermatology physicians in formulating effective diagnostic and treatment strategies and herald a transformative era in healthcare.

Abstract
Pressure ulcers often become chronic wounds that are difficult to treat and that tend to recur after healing. In China, convincing data from randomised trials have demonstrated that the pharmaceutical preparations of Periplaneta americana (KangFuXin Liquid, KFX) have a significant efficacy for pressure ulcers. To provide more reference to the clinicians and experts, we conducted a meta-analysis based on the existing randomised controlled trials (RCTs). We searched the RCTs about KFX for the treatment of pressure ulcers published up to July 2022 in major English and Chinese databases with no language restriction, including PubMed, EMBASE, Web of Science (WOS), Cochrane Central Register of Controlled Trials (CENTRAL), China Network Knowledge Infrastructure (CNKI), Chinese Biomedicine (CBM), Chinese Scientific Journals Database (VIP), and WanFang database. Cochrane Handbook guidelines were used to assess the risk of bias and to evaluate the methodological quality of included RCTs. Estimates of the intervention's effects are expressed as the risk ratio (RR) (95% CI) for binary outcomes and mean difference or standardised mean difference (95% CI) for continuous outcomes. We applied fixed or random effects models, and all analyses were performed using Review Manager version 5.4 and Stata/SE version 12.0. We included 22 studies with a total of 1575 participants. Compared with controls, KFX combined with basic wound care or KFX combined with basic wound care and another topical drug or physical treatment significantly increase clinical efficacy (RR: 1.17; 95% CI, 1.06-1.28; P = 0.001; I2 = 81%) and shorten the complete healing time (MD = -5.11; 95% CI [-8.19, -2.02]; P = 0.001) for pressure ulcers. Subgroup analysis showed a significant difference in the total clinical effect rate between KFX combined with basic wound care and controls. (n = 1018, RR 1.21, 95% CI [1.07, 1.36], I2 = 82%, P = 0.003). No difference was found in the total clinical effective rate between patients using KFX combined with basic wound care and another topical drug or physical treatment with controls (KFX combined with basic wound care and topical physical treatment: n = 267, RR 1.15, 95% CI [0.86, 1.52], I2 = 87%, P = 0.34; KFX combined with basic wound care and topical drug: n = 290, RR 1.05, 95% CI [0.80, 1.37], I2 = 86%, P = 0.71). Based on treatment duration, subgroup analysis indicated that increasing treatment duration increased the total clinical effective rate when treatment duration was not long. (treatment duration: 14 days: n = 158, OR 5.48, 95% CI [1.47, 20.43], I2 = 0%, P = 0.01; 21 days: n = 132, OR 5.93, 95% CI [1.86, 18.91], I2 = 65%, P = 0.003). When treatment duration was 28 days or 30 days, the results showed that there was no significant difference in total clinical effective rate between interventions and controls (treatment duration: 28 days: n = 107, OR 3.04, 95% CI [0.25, 37.32], I2 = 50%, P = 0.38; 30 days: n = 256, OR 0.58, 95% CI [0.11, 3.15], I2 = 65%, P = 0.53). No data on side effects were reported in any of the 22 studies. The conclusion is that the combination of KFX and basic wound care is effective in increasing the total clinical effectiveness and shortening the complete healing time of pressure ulcers.

Abstract
Psoriasis is a recurring systemic disease that can be treated with biologics to some effect. However, precisely targeting inflammatory mediators may disrupt immune system homeostasis and lead to new conditions. Here, we report a case of psoriasiform dermatitis (PsoD) caused by IL-17 inhibitors (IL-17i) namely secukinumab treatment for psoriasis. This case proposes an effective use of Janus kinase inhibitor (JAKi) tofacitinib to confront lesions induced by IL-17i. This is the first case report of PsoD caused by secukinumab treated with tofacitinib.

Abstract
Pruritus of chronic spontaneous urticaria (CSU) is one of the most common and irritating sensations that severely affects the quality of life. However, the changes in the functional connectivity (FC) between thalamic subregions and other brain regions have not been fully elucidated. This study aimed to explore the potential changes in brain neural circuits by focusing on various subregions of the thalamus in patients with CSU pruritus to contribute to the understanding of chronic pruritus from the perspective of central mechanisms. A total of 56 patients with CSU and 30 healthy controls (HCs) completed the data analysis. Urticaria Activity Score 7 (UAS7), pruritus visual analog score (VAS-P), Dermatological Life Quality Index (DLQI), and immunoglobulin E (IgE) values were collected to assess clinical symptoms. Seed-based resting-state functional connectivity (rs-FC) analysis was used to assess relevant changes in the neural circuits of the brain. Compared to HCs, seeds within the caudal temporal thalamus (cTtha) on the right side of patients with CSU showed increased rs-FC with the cerebellum anterior lobe (CAL). Seeds within the lateral prefrontal thalamus (lPFtha) on the right side showed increased rs-FC with both CAL and pons, while those within the medial prefrontal thalamus (mPFtha) on the right side showed increased rs-FC with both CAL and the dorsal lateral prefrontal cortex (dlPFC) on the right side. Seeds within the posterior parietal thalamus (PPtha) on the right side showed increased rs-FC with the cerebellum posterior lobe (CPL) on the left side. The UAS7 values and IgE levels were positively correlated with the rs-FC of the right dlPFC. Our results suggest that patients with CSU may exhibit stronger rs-FC alterations between certain thalamic subregions and other brain regions. These changes affect areas of the brain involved in sensorimotor and scratching. Trial registration number [http://www.chictr.org.cn], identifier [ChiCTR1900022994].

Abstract
Chronic prurigo (CPG) is a chronic inflammatory disease characterized by intense pruritus, and therapy is often challenging due to its unclear pathogenesis. Here, we report four patients with refractory CPG from different backgrounds who experienced failure of conventional therapy and were controlled with dupilumab, accompanied by a significant decrease in pruritus numerical rating scale, dermatology life quality index, and investigator global assessment, without adverse effects. Furthermore, dupilumab improved the condition of asthma in CPG patients along with an increase in asthma control test scores.

Abstract
Objective: To investigate the individual external dose level of some interventional radiology staffs from 2016 to 2020 in Tianjin City. Methods: All 2068 interventional radiology staffs who were included in the work of the Radiation Monitoring Project from 2016 to 2020 were selected as study subjects in March 2021. The individual dose monitoring results of interventional radiology staffs of different ages, working years, time and medical institutions were analyzed. Results: Among 2068 interventional radiology workers, 1406 (67.99%) were male and 662 (32.01%) were female. The age was 44.6 (39.2, 50.3) years, and the working years was 10.5 (4.3, 14.6) years. The annual effective doses per capita of 40-49 age group and ≥50 age group were higher than that of 30-39 age group (P<0.05) . The annual effective dose per capita of 5-9 working years was higher than that of <5 working years, and the annual effective dose per capita of 10-29 working years was higher than that of 5-9 working years (P<0.05) . The median per capita annual effective dose of the interventional radiology staffs was 0.164 mSv. There were 1976 interventional radiology staffs with an annual effective dose of <0.50 mSv/a (95.6%) . The collective dose distribution ration SR(0.5) was 41.1%. The difference of effective dose per capita in each year was statistically significant (H=19.23, P<0.05) . The per capita annual effective dose of interventional radiology staffs in tertiary medical institutions was higher than that in secondary medical institutions, and the difference was statistically significant (P<0.05) . Conclusion: The personal dose of interventional radiology staffs in Tianjin City is at a low level. It is necessary to emphasize the radiation hazard protection of interventional radiology staffs in tertiary medical institutions, 40-49 years old, ≥50 years old age groups and 5-9, 10-29 working years groups.

Abstract
Case Report We present the case of a 51-year-old male who experienced temporary desquamation and recurrent burning sensation in primary skin lesions after the injection of dupilumab. The scaling lasted for 1 week and subsided, while the burning became aggravated with each injection of dupilumab, which gradually subsides after 8 weeks, and there was no recurrence since then. Conclusion Dupilumab is an emerging and efficacious biologics medication for AD. The burning sensation and scaling we report may be the adverse events of dupilumab. Rare adverse reactions to biologics deserve the attention of physicians.

Abstract
Contact dermatitis and facial contact dermatitis caused by pesticides are not uncommon in China. However, clinically, due to the wide variety of pesticides, they mainly appear in the form of case reports. We reported a 70-year-old male patient developed facial irritant contact dermatitis (ICD) due to pyraclostrobin which was sprayed on his face. Initially, he felt facial burning and tingling, and localized erythematous-edematous and scaly rash appeared on his face as well as front hairline scalp. During the outpatient visit, the main symptoms were a facial burning sensation, itching, and tingling. The patient’s facial lesions improved after treatment. To better protect the skin of agricultural workers, preventive measures should be undertaken, such as personal protective equipment, gas masks, protective clothing and goggles, which are indispensable for manual pesticide spraying. Pyraclostrobin diluted according to the instructions is a potential source of ICD. Agricultural workers should undertake preventive measures during manual pesticide spraying. Safety education and publicity are particularly important. We need dermatologists to spread knowledge and agricultural workers to develop the right protective habits.

Abstract
Grover’s disease (GD), also known as Transient acantholytic dermatosis, has no typical clinical rash features. It usually occurs in elderly white men but very rarely in China. This is a disease of acantholysis and dyskeratosis, which is usually considered to be spontaneous remission. The skin lesions of the disease are diverse, and the main symptom is severe itching. We have reported a case of GD in a 14-year-old Chinese Tibetan male whose clinical manifestations were pruritic red papule, generalized red papules, papulo vesicles and blisters ranging from millet rice to soybean size. Skin lesions change rapidly and variously. In order to confirm the diagnosis, we have done skin biopsies, immunofluorescence, dermoscopy, microscopy and other examinations. Pathological skin biopsy showed acantholysis. Intraepidermal blisters and the presence of blisters on the basal cells as well as under the stratum corneum can be observed on the same pathological section. Type IV collagen immunohistochemistry showed blisters in the epidermis. The diagnosis of GD depended on the exclusion of other diseases. After we performed whole exon sequencing (WES) on DNA from the patient’s blood, pathogenic gene mutations were not found. Pustular psoriasis, Subcorneal pustular dermatosis, Herpesvirus infections, Dermatitis herpetiformis, Pemphigus vulgaris, Norwegian scabies, Darier’s disease, and Hailey-Hailey disease were all excluded. We successfully treated adolescent GD with minocycline combined with methotrexate. The patient was followed up for 19 months without recurrence.

Abstract
Purpose Despite recent advances in the treatment of prurigo nodularis, conventional treatment suffers from a dilemma of poor efficacy. The clinical use of Janus kinase (JAK) inhibitors in the treatment of Prurigo nodularis has rarely been explored. Patients and Methods We present a case of prurigo nodularis successfully treated with, JAK inhibitor tofacitinib with no adverse effects. Results This case report of successful treatment shows a good clinical efficacy of using JAK inhibitor tofacitinib in the treatment of prurigo nodularis. Cytokines may be an important cause of prurigo nodularis. Conclusion JAK inhibitor tofacitinib may be a new option for the treatment of prurigo nodularis, especially for patients who have failed conventional treatment.

Abstract
BACKGROUND Lichen simplex chronicus (LSC) is characterized by localized lichenification and intense itching. It has been reported that the added use of liquid nitrogen cryotherapy (LNC) for LSC has significant efficacy and notable safety. Therefore, we conducted a meta-analysis based on existing randomized controlled trials (RCTs). METHOD We searched RCTs on LNC for LSC published up to August 2020 using various databases, including PubMed, EMBASE, Web of Science, Cochrane Central Register of Controlled Trials, China Network Knowledge Infrastructure (CNKI), Chinese Biomedicine (CBM), Chinese Scientific Journals Database (VIP), and WanFang Database. Other studies were manually identified using the references cited in reviews. We applied fixed- or random-effects models, and all analyses were performed using Review Manager 5.4 software. RESULTS Twelve RCTs involving 1,066 participants provided eligible data for the meta-analysis. Based on the clinical effective rate, LNC treatment of LSC (risk ratio, RR 1.25, p = 0.005, I2 = 82%) was superior to controls. Subgroup analysis showed that the use of LNC alone (RR 1.04, I2 = 95%, p > 0.05) is not more effective than other therapies in the treatment of LSC, but the addition of LNC to the existing treatment increases the total clinical efficacy. Furthermore, the combined effect of LNC and topical medication (RR 1.39, I2 = 0%, p < 0.0001) was better than that of LNC and oral medication (RR 1.30, I2 = 0%, p < 0.00001). Greater frequency of LNC treatment did not improve the efficacy (thrice a week: RR 1.39 [1.21, 1.60]; twice a week: RR 1.27; once every 2 weeks: RR 1.32). Data from 6 RCTs with 508 participants showed no significant difference in AEs (p = 0.31) associated with added LNC treatment. CONCLUSION The addition of LNC (applying a cotton swab soaked with liquid nitrogen to wipe the lesion for approximately 10 s each time) to topical ointments, is effective and safe in the treatment of LSC. Increasing the treatment frequency of LNC did not necessarily improve the efficacy.

Abstract
AIMS In China, apple production areas are largely from the coastal to inland areas and across varied climate zones. However, the relationship among soil micro-organisms, environmental factors and fruit quality has not been clearly confirmed in orchards. Here we attempted to identify the variation of soil bacteria in the main apple producing regions and reveal the relationship among climatic factor, soil properties, soil bacterial community and fruit quality. METHODS AND RESULTS Sixty soil samples were collected from six main apple producing areas in China. We examined the soil bacteria using bacterial 16S rRNA gene amplicon profiling. The results show that the soil bacterial diversity of apple orchards varied from the Bohai Bay Region to the Loess Plateau Region. Proteobacteria, Acidobacteria and Actinobacteria were the predominant taxa at the phylum level for all six areas. In the Bohai Bay and the Loess Plateau region, which are the two largest apple producing areas, Proteobacteria and Actinobacteria had the highest relative abundance, respectively. Furthermore, soil bacterial diversity showed positive correlation with the mean annual temperature (MAT), soil organic matter (SOM) and pH. Excluding a direct effect on the apple fruit quality, MAT exerted an indirect influence through soil SOM and pH to alter the relative abundance of dominant taxa and shift the bacterial diversity, which affects the apple fruit titratable acids and soluble solids. CONCLUSIONS Geographic variables underlie apple orchard soil bacterial communities vary according to spatial scale. Environmental factors exert an indirect effect on apple fruit quality via shaping soil bacterial community. SIGNIFICANCE AND IMPACT OF THE STUDY This study provides a list of bacteria associated with environmental factors and the ecological attributes of their interactions in apple orchards, which will improve our ability to promote soil bacterial functional capabilities in order to reduce the fertilizer input and enhance the fruit quality.

Abstract
Although various factors were reported to be related to post-herpetic neuralgia (PHN), studies based on adequate and comprehensive data were absent. Data was extracted from cases of hospitalized patients with herpes zoster in dermatology department, Sichuan hospital of traditional Chinese medicine range from December, 2011 to February, 2018, and then cleaned to build prediction model with TREENET algorithms. Following evaluated the prediction model by ROC and confusion matrix, variables importance ranking and variables dependency analysis were performed, resulting in the importance ranking of factors for PHN and the dependency between factors and PHN. Based on strict inclusion and exclusion criteria, 1303 (571 PHN and 732 normal controls) cases and 2958 indicators were selected. Model evaluation showed high ROC value (training sample = 0.985, test samples = 0.752) and high accuracy value (70.27%), which indicated that the model was predictive. After variables importance ranking and variables dependency analysis, 62 variables in the model were associated with the occurrence of PHN. Our study identified 62 variables related to PHN and revealed that various variables were the important risk factors for PHN, including age, MCHC, sodium and UA.

Abstract
Accurate control of the polarization states of laser light is important in precision measurement experiments. In experiments involving the use of a vacuum environment, the stress-induced birefringence effect of the vacuum windows will affect the polarization states of laser light inside the vacuum system, and it is very difficult to measure and optimize the polarization states of the laser light in situ. The purpose of this protocol is to demonstrate how to optimize the polarization states of the laser light based on the fluorescence of ions in the vacuum system, and how to calculate the birefringence of vacuum windows based on azimuthal angles of external wave plates with Mueller matrix. The fluorescence of 25Mg+ ions induced by laser light that is resonant with the transition of |32P3/2,F = 4, mF = 4 → |32S1/2,F = 3, mF = 3 is sensitive to the polarization state of the laser light, and maximum fluorescence will be observed with pure circularly polarized light. A combination of half-wave plate (HWP) and quarter-wave plate (QWP) can achieve arbitrary phase retardation and is used for compensating the birefringence of the vacuum window. In this experiment, the polarization state of the laser light is optimized based on the fluorescence of 25Mg+ ion with a pair of HWP and QWP outside the vacuum chamber. By adjusting the azimuthal angles of the HWP and QWP to obtain maximum ion fluorescence, one can obtain a pure circularly polarized light inside the vacuum chamber. With the information on the azimuthal angles of the external HWP and QWP, the birefringence of the vacuum window can be determined.

Abstract
We present a simple method to measure the degrees of circular polarization (DoCP) of laser light inside a vacuum chamber and the birefringence of a vacuum window by detecting the fluorescence emitted by Doppler cooled ions in an ion trap. Imperfect laser polarization will cause ions to be pumped to the dark state which will decrease the fluorescence rates of the ions. With a simulation based on the rate equations of the relevant energy levels of 25Mg+ ions, we find that the fluorescence rate is sensitive to the DoCP of the laser. Based on the simulation result, we present a new method to optimize the DoCP of the laser inside the vacuum chamber by adjusting fast axis azimuthal angles of a half-wave plate and a quarter-wave plate outside the vacuum chamber. The laser light is optimized to be circularly polarized with an uncertainty of the DoCP of 7.8 × 10-5. With the obtained polarization information on both sides of the vacuum window and treating the vacuum window as an unknown wave plate, the phase delay and the fast axis azimuthal angle of the vacuum window can be determined in the form of Mueller matrix. The phase delay is determined to be 197.60(39)°, and the fast axis azimuthal angle is determined to be 104.00(5)°.

Abstract
A wide range of pharmacological and nonpharmacological interventions for chronic urticaria (CU) have been evaluated in systematic reviews (SRs). We conducted an umbrella review of SRs of the effectiveness and safety of pharmacological and nonpharmacological interventions for CU, which allow the findings of separate reviews to be compared and contrasted and thereby provide decision makers in healthcare with the evidence they need.We included SRs evaluating pharmacological and nonpharmacological interventions for CU. Comprehensive searches were conducted in 7 bibliographic databases, relevant journals up to July 2018. Two reviewers independently assessed the studies' relevance and quality. The assessment of multiple systematic reviews tool and grading of recommendations assessment, development and evaluation method was used to assess the methodological quality of the SRs and classify the quality of the outcomes.In total, 41 SRs were included. Thirty-seven reviews performed quantitative research syntheses, and 4 reviews performed qualitative research syntheses. The majority of SRs evaluated interventions based on combination therapies, antihistamines, traditional Chinese medicines, autohemotherapy, omalizumab, acupuncture, cyclosporine, and leukotriene receptor antagonist. Positive intervention outcomes were reported in the majority (75.32%) of the reviews. However, the methodological quality and evidence quality of the reviews were generally poor.There is some evidence to support a variety of interventions for CU. However, there was much heterogeneity in evidence quality among SRs. Many of the SRs had methodological weaknesses that make them vulnerable to bias. Moreover, there remained little information on the relative effectiveness of one intervention compared with another. Therefore, further SRs that adherence to strict scientific methods are necessary, and primary studies make comparisons between the different treatment options directly.

Abstract
OBJECTIVE To analyze the expression of profilin-1 in endothelial cells of rats with acute myocardial infarction. MATERIALS AND METHODS Twenty adult male Wistar rats were randomly divided into the myocardial infarction (model) group (n=10) and sham-operation (control) group (n=10). The expression of profilin-1 and phosphorylated extracellular signal kinase (pERK1/2) in aortic endothelial cells, indexes of endothelial injury [levels of endothelial microparticles (EMPs) and nitric oxide (NO)], indexes of myocardial injury [cardiac troponin T (cTnT) and creatine kinase-MB (CK-MB)], and mRNA levels of myocardial apoptotic factors (P53, Fas, Bax, and Bcl-2) in rats between the two groups were compared. RESULTS The expression of profilin-1 and pERK1/2 in aortic endothelial cells of rats in the model group was higher than in the control group (p<0.05), the levels of EMPs were increased, and NO levels were lower (p<0.05); cTnT and CK-MB in myocardial tissue, and mRNA of pro-apoptotic factors (P53, Fas, and Bax) were increased, whereas Bcl-2 mRNA was decreased (p<0.05). The protein expression of profilin-1 and pERK1 was positively correlated with the levels of cTnT, CK-MB, EMP, P53, Fas, and Bax, and negatively correlated with the levels of NO and Bcl-2 (p<0.05). CONCLUSIONS The high expression of profilin-1 is an important mechanism of acute myocardial infarction, and is expected to become a new target for the treatment of myocardial infarction.

Abstract
Single-molecule FRET measurements have a unique sensitivity to protein conformational dynamics. The FRET signals can either be interpreted quantitatively to provide estimates of absolute distance in a molecule configuration or can be qualitatively interpreted as distinct states, from which quantitative kinetic schemes for conformational transitions can be deduced. Here we describe methods utilizing single-molecule FRET to reveal the conformational dynamics of the proteins responsible for DNA mismatch repair. Experimental details about the proteins, DNA substrates, fluorescent labeling, and data analysis are included. The complementarity of single molecule and ensemble kinetic methods is discussed as well.

Abstract
OBJECTIVE To design a new Arg-Gly-Asp (RGD) peptide that can specifically bind integrin αvβ3 and evaluate the possibility of using 131I-labeled peptide for imaging αvβ3-positive tumors. MATERIALS AND METHODS The structure of the RGD monomer was selected using V-life software. Based on the RGD monomer, a dimer of cyclic RGD [c(RGD)2] linked by Tyr-(D)Ser-Lys-(D)Ser-Ser with a Gly-Gly-(D)Ala-Gly side chain on the lysine residue was synthesized. 131I-c(RGD)2 was synthesized using the chloramine-T (ChT) method, and the octanol-water partition coefficient was experimentally measured. To evaluate its binding affinity and selectivity, its equilibrium dissociation constant (Kd) with U87 MG glioma cells was measured in vitro, while whole body imaging and biodistribution were assessed in vivo in mice bearing U87 MG xenografts. RESULTS The optimal structure of the monomer was cyclic [-Cys-Arg-Gly-Asp-(D)Ser-Cys-]. The 131I-c(RGD)2 molecule exhibited good stability and was highly hydrophilic. The Kd value was (3.87 ± 0.05) × 10(-9) M, suggesting a high αvβ3-binding affinity and specificity. The tumors were clearly visualized at 3 and 6 h post-injection. Biodistribution data of the 131I-c(RGD)2 molecule showed rapid clearance from the blood and predominant accumulation in the tumor and kidney. The tumor-to-normal tissue (T/NT) ratio increased over time. At 24 h post-injection, the tumor-to-liver, tumor-to-muscle, and tumor-to-blood ratios were 4.92, 4.29, and 5.00, respectively. CONCLUSIONS These results suggest that the 131I-c(RGD)2 molecule may serve as a promising tracer for the detection of αvβ3-positive tumors.

Abstract
Prediction of antiviral efficacy prior to treatment remains largely unavailable. We have previously demonstrated the clinical value of on-treatment hepatitis B virus (HBV) reverse transcriptase (RT) quasispecies (QS) evolution patterns. In this study, we aimed to elucidate the relevance for prediction of pretreatment HBV RT QS characteristics by comparing the performance of next-generation sequencing (NGS) and clone-based Sanger sequencing (CBS). Thirty-six lamivudine-treated patients were retrospectively studied, including 18 responders and 18 non-responders. CBS and NGS data of pretreatment serum HBV were used to generate RT QS genetic complexity and diversity scores, according to our previous studies. The ability of both methods to predict responsiveness was evaluated with receiver operating characteristic (ROC) curves. A cut-off value was generated on the basis of prediction ability. Responders had significantly higher pretreatment RT QS genetic complexity and diversity (in the first two parts, which overlapped with the S gene, at both the nucleotide and amino acid levels) than non-responders by NGS-based testing. NGS-based algorithms predicted response better than CBS in the ROC curve analysis. The mean distance of the second contig had the highest area under the curve (AUC) value. When the cut-off value was set to 0.007186, the difference between survival curves was significant (p 0.0090). Pretreatment HBV RT QS heterogeneity in the overlapping region of the RT and S genes could be a predictor of antiviral efficacy. NGS improves the predictions of virological outcomes relative to CBS algorithms. This may have important implications for the clinical management of subjects chronically infected with HBV.

Abstract
OBJECTIVE Heat shock protein (Hsp90) resides exclusively in the cytosol in normal cells, but is activated and then removes to the cell surface in tumor cells. The detecting upregulation or activation of Hsp90 is an early indicator of malignant behavior of cancer cells. Hsp90 has emerged as an important target for diagnosis or therapy of prostate cancer. In this study, we labeled Hsp90α specific monoclonal antibody (Hsp90α-mAb) with radioiodine Na131I and investigated its potential usage in diagnostic imaging of prostate tumor in xenograft mice model. METHODS Hsp90α-mAb was radioiodinated by using chloramine-T. The radiolabeling efficiency and radiochemical purity were assessed in vitro. 131I-Hsp90α-mAb was then injected into the nude mice bearing human prostate carcinoma. The planar gamma Imaging was performed at 3, 6, 9 and 12 h after injection. RESULTS The radiochemical purity of 131I-Hsp90α-mAb exceeded 95% after purification. This radiolabeled mAb was stable in human blood serum. In planar gamma imaging study, the prostate tumors in mice model were imaged clearly at 3h after injection of 131I-Hsp90α-mAb. CONCLUSIONS The results suggest that 131I-HSP90α-mAb could be a new promising molecular probe for diagnostic imaging of prostate tumors.

Abstract
AIM Observed associations of alcohol with colorectal cancer are prone to distortion by confounding and reverse causation. A Mendelian randomization approach provides an unbiased estimate of the association using the aldehyde dehydrogenase 2 (ALDH2) variant as a surrogate of alcohol exposure. METHOD A meta-analysis was performed to assess the association between the ALDH2 genotype and colorectal neoplasia, using the ALDH2 genotype as a marker of alcohol intake. RESULTS The pooled odds ratio (OR) of colorectal neoplasia was 1.31 (95%CI, 1.01-1.70) for the Glu/Glu vs the Lys/Lys genotype. There was no evidence of interstudy heterogeneity (P = 0.12, I² = 42.7). The overall risk for Glu/Lys heterozygotes relative to Lys/Lys homozygotes (under a fixed-effects model) was 1.13 (95%CI, 0.86-1.48). There was no evidence of publication bias for Glu/Glu or Glu/Lys analysis. CONCLUSION The result supports the role of alcohol in colorectal carcinogenesis based on a Mendelian randomization approach.

Abstract
BACKGROUND Recent studies suggest that the appearance of anti-HLA antibodies in the early posttransplant period is associated with an increased incidence of acute and chronic rejection months later. However, very little is known about the prevalence of anti-HLA antibodies at the time that the rejection episodes are diagnosed. The purpose of this study was to analyze retrospectively 420 sera from 263 renal allograft recipients who were readmitted to the hospital for any reason between 1989 and 1998 in order to determine if a correlation existed between the presence of donor-specific anti-HLA antibodies and graft rejection. METHODS Sera were assayed for IgG HLA class I and II antibodies by ELISA. The ELISA results were analyzed using contingency tables with Fisher's exact test and compared with mismatched antigens in the donor. RESULTS Antibodies to donor HLA class I molecules in the posttransplant sera were extremely rare, occurring in only 6 of the 420 sera (1.4%) analyzed. Antibodies to donor class II antigens were slightly more common, occurring in 25 of the 420 sera (6%). In 21 of these 25 cases (84%), the presence of donor-specific HLA class II antibodies was associated with episodes of either acute (n=14) or chronic rejection (n=7). Five patients had antibodies to both class I and class II donor antigens, and all five of them lost their grafts to rejection. CONCLUSION Although the presence of donor-specific HLA antibodies presented a significant risk for acute or chronic rejection, 77% of all acute and chronic rejections occurred in patients without detectable HLA antibodies.

Abstract
BACKGROUND Although cigarette smoking is known to have detrimental effects on the immune system, the nature of the immunosuppressive agent or agents is poorly understood. OBJECTIVE The purpose of the current study was to evaluate the effects of cigarette smoke extracts from high-tar (unfiltered Camel), medium-tar (Marlboro), and low-tar (Carlton) cigarettes on the in vitro production of IL-1beta, IL-2, IFN-gamma, and TNF-alpha. METHODS The concentrations of hydroquinone and catechol in cigarette smoke extracts were determined by using HPLC. Human PBMCs were treated with cigarette smoke extracts, hydroquinone, or catechol, and stimulated with anti-CD3 and phorbol-12-myristate-13-acetate. Cytokine levels in the supernatants were quantified by ELISA. RESULTS Pretreatment of PBMCs with cigarette smoke extracts derived from a single high- or low-tar cigarette suppressed the production of IL-1beta, IL-2, IFN-gamma, and TNF-alpha by greater than 90% without significant loss of cell viability. Nicotine, at a concentration comparable with that found in the highest-tar cigarettes (200 microg/mL), suppressed the production of IL-2, IFN-gamma, and TNF-alpha by only 21% to 38%. Catechol (50 micromol/L) inhibited production of IL-2 and IL-1beta by 62% to 73% but had little effect on TNF-alpha or IFN-gamma production. In contrast, hydroquinone inhibited the production of all 4 cytokines with IC(50) values ranging from 3 micromol/L(IL-1beta) to 29 micromol/L (IFN-gamma). However, HPLC determination of the hydroquinone concentrations in cigarette smoke extracts from single Camel (33+/-4 micromol/L), Marlboro (13+/-2 micromol/L), and Carlton (<1 micromol/L) cigarettes clearly demonstrated that the potent inhibitory effects of the low-tar cigarettes could not be accounted for by either hydroquinone or catechol. CONCLUSION These studies indicate that cigarette smoke contains potent inhibitors of cytokine production, at least one of which is present even in low-tar cigarettes.

Abstract
A critical requirement for cancer vaccines is that they stimulate CD8+ T cell responses. In this study, we tested the ability of a polyvalent melanoma vaccine to induce CD8+ T cell responses to the melanoma associated antigens MAGE-3 and Melan A/MART-1. Fifteen HLA-A2+ patients with resected malignant melanoma were immunized with the vaccine s.c. every 2-3 weeks. CD8+ T cells in peripheral blood reacting to HLA-A2 restricted epitopes on MAGE-3 (FLWGPRALV) and Melan A/MART-1/(AAGIGILTV) were quantitated using a filter spot assay at baseline and following 4 immunizations. Vaccine immunization induced CD8+ T cells reacting to one or both of these peptides in 9 of the 15 (60%) patients. These cells were CD8+ and HLA-A2 restricted, as reactivity was abrogated by monoclonal antibodies (MAbs) to CD8 and class I HLA, but not by anti-CD4. All responding patients remained recurrence-free for at least 12 months (median 15 months, range 12 to >21 months), whereas melanoma recurred within 3-5 months in non-responders. The differences in outcome were unrelated to differences in disease severity or overall immunological competence between responders and non-responders. Our results demonstrate directly that MAGE-3 and Melan A/MART-1 can stimulate CD8+ T cell responses in humans, and suggest that these responses are protective and surrogate markers of vaccine efficacy.

Abstract
The deformity of the bilateral cleft lip is complicated. The routine procedure often results in secondary deformities, such as over-tight lip, and over-thin vermilion. The paper introduces a modified straight-line procedure that has been used in 16 patients with satisfactory results. This one-stage procedure employed a nasolabial flap and two small triangular flaps to lessen the tension of sutrue and lengthen the anterior lip as well as create a natural feature of the vermillion border. The method overcame imperfection of routine ones and achieved functional repair of the lip that would facilitate the development of the columella and anterior lip.

Abstract
We have constructed antigen-specific chimeric human T cell receptor (TCR) molecules deleted of the transmembrane domain and containing the signal sequence for the biosynthesis of the phosphatidyl inositol glycan (GPI) linkage. These membrane-anchored forms of the TCR alpha and beta chains have been expressed in non-T cells, and they are recognized by alpha or beta TCR specific monoclonal antibodies. We have utilized both immunochemical methods and flow cytometry to prove that the enzyme phosphatidylinositol phospholipase C (PI/PLC) is able to cleave the GPI anchored TCR as a heterodimer from the CHO cell surface. We have demonstrated that the alpha/beta TCR heterodimer on the surface of CHO cells will recognize and bind polymers containing fluorescein (FL-polymer), and the binding activity is completely eliminated by the enzyme, PI/PLC. Moreover, soluble forms of the alpha/beta heterodimer will bind tightly to FL substituted sepharose, which demonstrates the retention of biological activity by the TCR after solubilization. Molecular modelling of the putative antigen binding site of the alpha FL beta FL TCR was derived from the known atomic coordinates of eight different hapten or peptide specific antibodies. Mutagenesis of several residues predicted from the model to be important in FL binding gave results consistent with involvement of Ig equivalent CDR2 and CDR3 domains in the antigen binding pocket. Therefore, using a model hapten system in studying recognition of the TCR independent of MHC interactions, we conclude that amino acid residues located in similar positions within CDR domains as compared to the case of MHC restricted TCR recognition are used in the binding of either hapten or peptide antigens.

Abstract
We have isolated T cell receptor (TCR) cDNAs from fluorescein (FL)-specific human T cell clones (alpha FL beta FL), and transferred them to TCR beta- Jurkat cells in order to study direct FL-binding to the TCR. Using either FL-conjugated polymers (FL-polymer) or FL-substituted Sepharose beads, we are able to demonstrate the direct binding of antigen to the T cell surface, and the functional activation of the T cell transfectants. We present evidence against the involvement of major histocompatibility complex (MHC) molecules or antigen presentation in the interaction of FL with the alpha FL beta FL transfectants. Additionally, we have examined the effect of ring substitutions on the FL molecule as well as specific alterations of substituents attached to the 5' position, and we have found that all of them interfere with the functional recognition of the alpha FL beta FL TCR. These experiments demonstrate that TCRs like antibodies have intrinsic affinities for antigen, even without the involvement of MHC molecules.
