RESUMEN
BACKGROUND: Neisseria gonorrhoeae antimicrobial resistance (AMR) is an urgent public health threat. With dissemination of FC428-related clones, the efficacy of ceftriaxone has become controversial. METHODS: Agar dilution and whole genome sequencing were used to analyze AMR. RESULTS: High resistance to penicillin (75.2%), tetracycline (87.9%), ciprofloxacin (98.3%), ceftriaxone (8.9%), cefixime (14.3%), and azithromycin (8.6%) was observed among 463 isolates first collected in China in 2021. All penA-60.001 clones exhibited resistance to ceftriaxone or cefixime, and 1 of the 12 cases was resistant to azithromycin. ngMAST and ngSTAR of penA-60.001 isolates showed that single-nucleotide polymorphisms in the porB, tbpB, ponA, gyrA, and parC genes were the major causes of different sequence types. MLST-7365 (n = 5) and MLST-1903 (n = 3) were main genotypes, and the other 4 strains featured MLST-10314, MLST-13871, MLST-7827 and MLST-1600. Furthermore, resistance markers (eg, penA, blaTEM-1, blaTEM-135) and virus factors were detected. Most penA-60.001 strains were fully mixed with global FC428-related clones; 2021-A2 and F89 had the same origin; and 2021-A1 exhibited a unique evolutionary trajectory. CONCLUSIONS: Results provide the first demonstration of extremely severe AMR rates of N gonorrhoeae in China in 2021, particularly strains with ceftriaxone decreased susceptibility. The sustained transmission of penA-60.001 subclones might further threaten treatment effectiveness.

OBJECTIVES: To explore the risk factors for hemorrhagic cystitis (HC) in children with ß-thalassemia major (TM) undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT). METHODS: A retrospective analysis was conducted on clinical data of 247 children with TM who underwent allo-HSCT at Shenzhen Children's Hospital from January 2021 to November 2022. The children were divided into an HC group (91 cases) and a non-HC group (156 cases) based on whether HC occurred after operation. Multivariable logistic regression analysis was used to explore the risk factors for HC, and the receiver operating characteristic curve was used to analyze the predictive efficacy of related factors for HC. RESULTS: Among the 247 TM patients who underwent allo-HSCT, the incidence of HC was 36.8% (91/247). Univariate analysis showed age, incompatible blood types between donors and recipients, occurrence of acute graft-versus-host disease (aGVHD), positive urine BK virus deoxyribonucleic acid (BKV-DNA), and ≥2 viral infections were associated with the development of HC after allo-HSCT (P<0.05). Multivariable analysis revealed that incompatible blood types between donors and recipients (OR=3.171, 95%CI: 1.538-6.539), occurrence of aGVHD (OR=2.581, 95%CI: 1.125-5.918), and positive urine BKV-DNA (OR=21.878, 95%CI: 9.633-49.687) were independent risk factors for HC in children with TM who underwent allo-HSCT. The receiver operating characteristic curve analysis showed that positive urine BKV-DNA alone or in combination with two other risk factors (occurrence of aGVHD, incompatible blood types between donors and recipients) had a certain accuracy in predicting the development of HC after allo-HSCT (area under the curve >0.8, P<0.05). CONCLUSIONS: Incompatible blood types between donors and recipients, occurrence of aGVHD, and positive urine BKV-DNA are risk factors for HC after allo-HSCT in children with TM. Regular monitoring of urine BKV-DNA has a positive significance for early diagnosis and treatment of HC.

BACKGROUND: Myiasis is caused by dipterous larvae, and rarely affects the mouth. Diagnosis by traditional means is easy to be confused with other similar species. Here, we report a case of oral myiasis, in a 5-month-old infant who was diagnosed by morphological examination and molecular biological methods. CASE PRESENTATION: A 5-month old infant with acute myeloid leukemia was admitted due to recurrent skin masses for more than 4 months. The infant had lip swelling, which prevented him from closing the mouth and membranes were present in his mouth and there were also oral ulcers and erosions. Ten maggots were found in the mouth and one in the ear canal with pus flowing out and were confirmed as the third stage larvae of Sarcophaga ruficornis by morphological examination and a comparison of sequence of cytochrome oxidase subunit 1 (COX1) gene. After removal of the maggots and chemotherapy, the infant 's condition was gradually improved. CONCLUSIONS: To the best of our our knowledge, this is the first neonatal oral myiasis case reported in China and its diagnosis requires a high index of suspicion. Microscopy combined with specific DNA sequence analysis is an effective technological tool to provide rapid diagnoses of the larva specimen and cases of rare diseases, as illustrated in the current case.

Staphylococcus aureus is a common foodborne pathogen that is ubiquitous in nature. Consumption of contaminated foods, such as dairy products, can lead to food poisoning caused by heat-stable staphylococcal toxins that are not easily destroyed during pasteurization. The objective of this study was to investigate the growth kinetics of S. aureus and background microorganisms in camel milk stored at different temperatures between 8 and 43°C using one-step kinetic analysis to estimate the kinetic parameters from the observed growth curves. The growth of S. aureus showed apparent lag, exponential, and stationary phases, whereas no or negligible lag phase was observed for background microorganisms. Data analysis showed that the estimated minimum, optimum, and maximum growth temperatures were 5.9, 42.0, and 49.2°C for S. aureus, and 3.0, 38.6, and 49.2°C for the background microorganisms, respectively. The estimated optimum specific growth rate was higher for S. aureus (1.24 h-1) than for background microorganisms (0.995 h-1). This study found that camel milk may inhibit the growth of S. aureus, as it exhibits a lower specific growth rate than that in cow milk or cooked potato. It also has a longer lag phase than that in cow milk at comparable temperature ranges. This unique property is probably related to the presence of some antimicrobial compounds naturally occurring in camel milk. Validation of kinetic parameters and models showed that the root mean square error of prediction was only 0.5 log cfu/mL for S. aureus and background microorganisms, suggesting that the models are reasonably accurate. These models can be used for conducting risk assessments of S. aureus and predicting the general microbiological shelf life of camel milk to prevent foodborne staphylococcal poisoning.

Objective: This study aims to comprehensively evaluate embolization coils in treating postoperative bronchopleural fistula (BPF). Methods: A systematic review based on PubMed, Embase, and The Cochrane Library studies was conducted. All cases receiving embolization coils in treating postoperative BPF were included. The primary outcome was the efficacy of embolization coils in achieving closure of postoperative BPF. Results: 20 patients from 9 studies were included in this systematic review. A median number of 3 (range: 1-10) embolization coils with sealants obtained a complete closure rate of 80% in patients with postoperative BPF with sizes ranging from 2 to 3.1 mm. Three patients with BPF over 3 mm and one with multiple organ failure failed this treatment. Two cases of coil migration were reported without causing respiratory failure or fistula recurrence. Conclusion: Embolization coils might be considered a safe and effective bronchoscopic treatment for small postoperative BPF of less than 3 mm in size. More extensive and rigorous studies are needed to further evaluate and confirm the optimal use of embolization coils in the context of an alternative to surgical repair.
RESUMEN
OBJECTIVE: We aimed to explore the prognostic significance of preoperative magnetic resonance imaging (MRI) variables and novel inflammatory indicators in predicting neurological recovery post-cervical traumatic spinal cord injury (TSCI) in the study. METHODS: We enrolled a total of 244 patients diagnosed with acute cervical TSCI from 2 hospitals and evaluated the prognostic value of MRI variables (intramedullary hemorrhage, intramedullary lesion length [IMLL], maximum spinal cord compression, and maximum canal compromise [MCC]) and novel inflammatory indicators (neutrophil-to-lymphocyte ratio [NLR], platelet-to-lymphocyte ratio, lymphocyte-to-monocyte ratio, and systemic immune-inflammatory index) in patients with acute cervical TSCI. RESULTS: Among the 244 patients, 140 (57.38%) exhibited improved AIS grade conversion at 1-year follow-up. The results revealed intramedullary hemorrhage, IMLL, MCC, neutrophils, and NLR were significantly different compared with follow-up AIS grade. Furthermore, IMLL, MCC, white blood cells, neutrophils, NLR, and lymphocyte-to-monocyte ratio correlated with the follow-up AIS grade by Spearman's correlation analysis. Multivariate analysis showed IMLL, intramedullary hemorrhage, NLR, and admission AIS grade emerged as independent predictors of AIS grade conversion. The receiver operating characteristic curve analysis showed that the novel model (combination of MRI variables, NLR, and admission AIS grade) produced a larger area under the curve compared with using only intramedullary hemorrhage, IMLL, NLR, or admission AIS grade individually. CONCLUSION: Intramedullary hemorrhage and IMLL and NLR are predictors of AIS grade conversion after cervical TSCI. Therefore, we suggest the combination of MRI variables and NLR for the prognostic prediction of AIS grade conversion in patients with cervical TSCI.
RESUMEN
Alpine wetlands are critical ecosystems for global carbon (C) cycling and climate change mitigation. Ecological restoration projects for alpine grazing wetlands are urgently needed, especially due to their critical role as carbon (C) sinks. However, the fate of the C pool in alpine wetlands after restoration from grazing remains unclear. In this study, soil samples from both grazed and restored wetlands in Zoige (near Hongyuan County, Sichuan Province, China) were collected to analyze soil organic carbon (SOC) fractions, arbuscular mycorrhizal fungi (AMF), soil properties, and plant biomass. Moreover, the Tea Bag Index (TBI) was applied to assess the initial decomposition rate (k) and stabilization factor (S), providing a novel perspective on SOC dynamics. The results of this research revealed that the mineral-associated organic carbon (MAOC) was 1.40 times higher in restored sites compared to grazed sites, although no significant difference in particulate organic carbon (POC) was detected between the two site types. Furthermore, the increased MAOC after restoration exhibited a significant positive correlation with various parameters including S, C and N content, aboveground biomass, WSOC, AMF diversity, and NH4+. This indicates that restoration significantly increases plant primary production, litter turnover, soil characteristics, and AMF diversity, thereby enhancing the C stabilization capacity of alpine wetland soils.
RESUMEN
BACKGROUND: This study aimed to evaluate the safety of enhanced recovery after surgery (ERAS) in elderly patients with gastric cancer (GC). AIM: To evaluate the safety of ERAS in elderly patients with GC. METHODS: The PubMed, EMBASE, and Cochrane Library databases were used to search for eligible studies from inception to April 1, 2023. The mean difference (MD), odds ratio (OR) and 95% confidence interval (95%CI) were pooled for analysis. The quality of the included studies was evaluated using the Newcastle-Ottawa Scale scores. We used Stata (V.16.0) software for data analysis. RESULTS: This study consists of six studies involving 878 elderly patients. By analyzing the clinical outcomes, we found that the ERAS group had shorter postoperative hospital stays (MD = -0.51, I2 = 0.00%, 95%CI = -0.72 to -0.30, P = 0.00); earlier times to first flatus (defecation; MD = -0.30, I² = 0.00%, 95%CI = -0.55 to -0.06, P = 0.02); less intestinal obstruction (OR = 3.24, I2 = 0.00%, 95%CI = 1.07 to 9.78, P = 0.04); less nausea and vomiting (OR = 4.07, I2 = 0.00%, 95%CI = 1.29 to 12.84, P = 0.02); and less gastric retention (OR = 5.69, I2 = 2.46%, 95%CI = 2.00 to 16.20, P = 0.00). Our results showed that the conventional group had a greater mortality rate than the ERAS group (OR = 0.24, I2 = 0.00%, 95%CI = 0.07 to 0.84, P = 0.03). However, there was no statistically significant difference in major complications between the ERAS group and the conventional group (OR = 0.67, I2 = 0.00%, 95%CI = 0.38 to 1.18, P = 0.16). CONCLUSION: Compared to those with conventional recovery, elderly GC patients who received the ERAS protocol after surgery had a lower risk of mortality.
RESUMEN
BACKGROUND: Ostomy is a common surgery usually performed to protect patients from clinical symptoms caused by distal anastomotic leakage after colorectal cancer (CRC) surgery and perforation or to relieve intestinal obstruction. AIM: To analyze the complications after transverse colostomy closure. METHODS: Patients who underwent transverse colostomy closure from Jan 2015 to Jan 2022 were retrospectively enrolled in a single clinical center. The differences between the complication group and the no complication group were compared. Logistic regression analyses were conducted to find independent factors for overall complications or incision infection. RESULTS: A total of 102 patients who underwent transverse colostomy closure were enrolled in the current study. Seventy (68.6%) patients underwent transverse colostomy because of CRC related causes. Postoperative complications occurred in 30 (29.4%) patients and the most frequent complication occurring after transverse colostomy closure was incision infection (46.7%). The complication group had longer hospital stays (P < 0.01). However, no potential risk factors were identified for overall complications and incision infection. CONCLUSION: The most frequent complication occurring after transverse colostomy closure surgery in our center was incision infection. The operation time, interval from transverse colostomy to reversal, and method of anastomosis might have no impact on the postoperative complications. Surgeons should pay more attention to aseptic techniques.
RESUMEN
Background and Aim: The aim of this study was to assess the quality and content of videos on Douyin and TikTok for their educational role on early screening of rectal cancer (RC). Methods: We conducted a search for videos related to RC on the Douyin and TikTok applications on 20 April 2023. The search was conducted in Chinese on Douyin and in English and Japanese on TikTok. A sample of the first 100 videos recommended by the software was selected for each language group. The content of the videos was evaluated using a content scorecard, while the quality of the videos was assessed using DISCERN. Subsequently, we conducted two partial correlations: one between the DISCERN score and the number of likes, and another between the video content score and the number of likes. Results: This study encompassed a total of 89 Chinese, 54 English, and 51 Japanese videos. After selection, 78 Chinese, 38 English, and 25 Japanese videos were identified to contain content related to early screening for RC, prompting further quality assessment. Notably, videos in the Chinese language showed the highest DISCERN score (P < 0.05). In terms of partial correlation analysis, it was observed that both the content score and DISCERN score did not show a significant correlation with the number of likes (P > 0.05). Conclusion: In terms of quality score and content score, the Chinese videos on Douyin show superiority over the English and Japanese videos on TikTok. However, there is potential for improving the overall appeal of the Chinese videos.
RESUMEN
With the day-night temperature and moisture levels changing every day, expansion and shrinkage of concrete slabs is always occurring; therefore, joints provide extra room for concrete slab deformation. The joint spacing in jointed plain concrete pavement (JPCP) is continuously affecting long-term pavement behaviors. In this study, data from the Long-Term Pavement Performance (LTPP) program were analyzed, and the behaviors of JPCP with different joint spacings were compared to discover the joint spacing effects. Since LTPP has an enormous database, three representative sections located in different states were selected for analysis, where the variable factors such as temperature, moisture, and average annual daily truck traffic (AADTT) were almost the same between the three sections. Three different joint spacings, including 15 ft (4.5 m), 20 ft (6 m), and 25 ft (7.5 m), were compared based on the collected LTPP data. The involved long-term pavement performances, such as average transverse cracking (count), average JPCP faulting, international roughness index (IRI), and falling weight deflectometer (FWD) deflections were compared between JPCP with different joint spacings. Based on the comparative analysis, the JPCP constructed with a 15 ft joint spacing demonstrated the best long-term performance. It showed no transverse cracking, the lowest average JPCP faulting, the best IRI value, and the smallest FWD deflection during the entire in-service period. With proper joint spacing, the cost of road maintenance throughout the life cycle could be significantly reduced due to there being less distress. Therefore, it is recommended to optimize the joint spacing to about 15 ft in JPCP in future applications.
RESUMEN
Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening immune-mediated disease that affects patients with known genetic defects and is increasingly found among those with autoimmune diseases and persistent infections. Talaromyces marneffei (TM) is a human opportunistic fungus that commonly infects immunodeficient or immunosuppressed individuals. Few TM-associated secondary HLH cases resulting from autoimmune deficiency have been reported previously. The current case study describes a pediatric patient hospitalized with recurrent fever and lymphadenopathy. The child had abnormal blood cell classification, and microscopy revealed mature granulocytes that phagocytized fungal spores. It was speculated that the patient was infected with TM. The pathogen was detected earlier than the blood culture and confirmed by metagenomic next-generation sequencing. Whole-exome sequencing revealed that the patient had complex mutations associated with immunodeficiency. This included a mutation in exon 3 of the CD40LG gene, c.346G>A, which may be linked to hyper-IgM syndrome, a primary immunodeficiency disease with immunoglobulin conversion recombination defects that could explain the patient's increased susceptibility to serious opportunistic infections. In addition, a heterozygous frameshift variant, c.820dup (p.Asp274GlyfsTer61), was detected in exon 6 of CARD9, a key gene associated with fungal immune surveillance. After 4 days of fungal treatment, the abnormal blood cell clusters disappeared, but other infections occurred in succession for 6 months after rehabilitation. The patient was followed with the aim of providing subsequent immunotherapy. This study found that infection can trigger HLH in HIV-negative individuals, highlighting the importance of early definitive identification of the causative agent and investigation of potential immunodeficiency.

Leukocyte esterase test (LET) detection is a simple and inexpensive test performed by urinalysis. This study investigated the predictive value of LET for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infection among men attending HIV and sexually transmitted infection (HIV/STI) clinics in Guangdong Province, China. A total of 5,509 urine samples were collected from HIV and sexually transmitted infection clinics in Guangdong Province between 2017 and 2019. Specimens from 5,464 males were tested by both LET and nucleic acid amplification test (NAAT). Of 5,464 males, 497 (9.1%) tested positive for CT or NG by NAAT, with respective prevalence rates of 6.4% (95% confidence interval [95% CI]: 5.8-7.1%) and 3.8% (95% CI: 3.3-4.3%), including 1.2% (95% CI: 0.9-1.4%) co-infected. Compared to the HIV-negative individuals, individuals living with HIV tend to have a higher prevalence of CT, NG and co-infection with CT and NG. The LET sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for CT were 46.4% (95% CI: 41.2-51.7%), 92.0% (95% CI: 91.2-92.7%), 28.4% (95% CI: 24.8-32.1%), and 96.1% (95% CI: 95.6-96.7%), respectively. The LET sensitivity, specificity, PPV, and NPV for NG were 68.4% (95% CI: 62.1-74.7%), 91.8% (95% CI: 91.1-92.6%), 25.0% (95% CI: 21.4-28.5%), and 98.7% (95% CI: 98.3-99%), respectively. Compared to the HIV-negative individuals, higher sensitivity and specificity were observed for HIV-positive individuals, but there was no statistical difference. The incremental cost-effectiveness ratio (ICER) using economic costs per additional person CT positive and NG positive was -$238.74 and -$145.60 compared with LET positive, respectively. LET is a cost-effective test and will be valuable for predicting CT and NG infection, which is highly prevalent in low- and middle-income countries.
RESUMEN
We herein report a rare case of co-infection of Pneumocystis jirovecii pneumonia and pulmonary CMV in a 3-month-old infant with X-linked severe combined immunodeficiency, in which diagnostic clues were obtained from the bronchoalveolar lavage fluid. We focus on the value of cytological diagnosis of P. jirovecii pneumonia and pulmonary CMV in the bronchoalveolar lavage fluid. Recognizing morphological characteristics of these pathogenic microorganisms is important to get timely diagnosis and treatment for the patients. Furthermore, repeated severe infections in infants should remind us to screen for immunosuppressed states.

Bone and teeth are derived from intrafibrillarly mineralized collagen fibrils as the second level of hierarchy. According to polymer-induced liquid-precursor process, using amorphous calcium phosphate precursor (ACP) is able to achieve intrafibrillar mineralization in the case of bone biomineral in vitro. Therefore, ACP precursors might be blended with any osteoconductive scaffold as a promising bone formation supplement for in-situ remineralization of collagens in bone. In this study, mesoporous silica nanoparticles with carboxyl-functionalized groups and ultra large-pores have been synthesized and used for the delivery of liquid like biomimetic precursors (ACP). The precursor delivery capacity of the nanoparticles was verified by the precursor release profile and successful mineralization of 2D and 3D collagen models. The nanoparticles could be completely degraded in 60 days and exhibited good biocompatibility as well. The successful translational strategy for biomineralization precursors showed that biomineralization precursor laden ultra large pore mesoporous silica possessed the potential as a versatile supplement in demineralized bone formation through the induction of intrafibrillar collagen mineralization.

BACKGROUND: In rare cases, odontogenic keratocysts (ODs) transform into squamous cell carcinoma. Intervals between the first attendance of a patient and the diagnosis of OD with malignant transformation vary from weeks to years. In this article, we report a case of malignancy derived from OD with a five-day delay in diagnosis. CASE SUMMARY: A 54-year-old woman was referred to Tongji Hospital in Wuhan, China with complaints of moderate pain, recurrent swelling, and pus discharge around her left maxillary lateral incisor for over 10 years. Physical examination revealed a fistula at the palatine-side mucoperiosteum of the left maxillary lateral incisor and enlarged lymph node in the left neck. Cone beam computed tomography revealed a cystic lesion with massive bone destruction from the left maxillary central incisor to the left secondary maxillary premolar and local bony destruction in the left first mandibular molar. The patient was clinically diagnosed with OD. Enucleation rather than marsupialization was performed given the risk factors of long history, recent aggravated pain, and massive bony destruction. Malignant transformation of OD was confirmed by pathologists 3 d after the operation. Radical surgery was performed, and lymph node metastasis was observed. The patient was subjected to postoperative radiotherapy and synchronous chemotherapy, and no local recurrence or distant metastasis was noted at one-year follow-up. CONCLUSION: Our case suggests that clinicians should be aware of the malignant transformation of OD, especially when patients present with a long history, massive cyst, chronic inflammation, recent persistent infections, aggravated pain, numbness around the cystic lesion, and lymph node enlargement.
RESUMEN
OBJECTIVE: To evaluate the effectiveness and safety of internal heat-type acupuncture needle (IHTAN) the-rapy in the treatment of post-stroke shoulder pain in apopletic patients. METHODS: According to the random number table, 96 patients with post-stroke shoulder pain were divided into IHTAN group and warm needle moxibustion group (nï¼48 in each one). Jianyu (LI15), Jianliao (TE14), Jianzhen (SI9), Binao (LI14) and Ashi points (Extra) on the affected side were selected in the two groups. For patients of the IHTAN group, internal warmth controllable acupuncture needles were inserted into the above-mentioned acupoints, and then connected to an internal heat acupuncture apparatus for stimulating the acupoints at 42 âï¼ 20 min every time, once a week, for 4 weeks. For patients of the warm needle moxibustion group, the above mentioned acupoints were stimulated with filiform needles attached with an ignited moxa-stick, once every other day, for 4 weeks. If the shoulder pain disappeared or basically disappeared, it was considered to be healed, if the pain was relieved, it was considered to be effective, ot-herwise, it was considered to be ineffective. The incidence of local skin injury including burn, empyrosis, silt blue, hematoma and infection, the heart rate, respiration, blood pressure, oxyhemoglobin saturation, blood routine (hemoglobin level, white blood cell [WBC] count, platelet count), creatase and dipolymer levels were recorded or detected. Additionally, the patients' satisfaction rate about the treatment environment was recorded. RESULTS: Following the treatment, of the 45 and 47 cases in the warm needle moxibustion and IHTAN groups, 5 (11.11%) and 20 (42.55%) were cured, 26(57.78%) and 21(44.68%) experienced marked improvement, and 14 (31.11%) and 6 (12.77%) had no apparent changes in their shoulder pain severity, with the total effective rates being 68.89% and 87.23%, respectively. The curative rate and total effective rate of the IHTAN group were significantly higher than those of the warm needle moxibustion group (P<0.01ï¼P<0.05). The incidence of skin injury of the IHTAN group was evidently lower than that of the warm needle moxibustion group (P<0.01), and the patients' therapeutic environment satisfaction rate was remarkably higher in the IHTNA group than in the warm needle moxibustion group (P<0.05). No significant differences were found between the two groups and between pre- and post-treatment in each group in the heart rate, respiration frequency, systolic and diastolic pressures, oxyhemoglobin saturation, hemoglobin content, WBC count, platelet count, and plasma dipolymer, creatine kinase, lactic dehydrogenase, and beta-hydroxybutyrate dehydrogenase levels (P>0.05). CONCLUSION: The IHTAN therapy is effective, safe and reliable in the treatment of post-stroke shoulder pain. In terms of the incidence of skin injury and the satisfaction degree of therapeutic environment, the internal heat-type acupuncture needle therapy is obviously superior to the warm needle moxibustion therapy.

OBJECTIVE: To observe the short-term and long-term therapeutic effects of internal heat-type acupuncture needle (IHTAN) therapy combined with acupoint injection of O3for post-stroke shoulder pain in apopletic patients. METHODS: Patients with post-stroke shoulder pain were divided into warm needle moxibustion ï¼ acupoint injection group (29 cases), acupoint injection group (30 cases) and IHTANï¼acupoint injection group (29 cases) according to the random number table. For acupoint injection, O3 solution (3 mL, 30 µg/mL) was injected into Jianyu (LI15), Jianliao (SJ14), Jianzhen (LI9), Binao (LI14) and Ashi points (4-6 acupoints every time) on the affected side, once every other day for 4 weeks. For warm needle moxibustion, the above mentioned acupoints were stimulated with filiform needles attached with an ignited moxa-stick, once every other day for 4 weeks. For IHTAN, the internal warmth controllable acupuncture needles were inserted into the above mentioned acupoints on the affected side, and then connected to an internal heat acupuncture apparatus for stimulating the acupoints at 42 âï¼ 20 min every time, once a week, for 4 weeks. The severity of shoulder pain was assessed by using visual analogue scale (VAS, 0-10 points), the upper limb joint motion function evaluated using Fugl-Meyer assessment scale (FMA, 0ï¼66 points), and the ability of daily living activities (ADL) evaluated using Barthel index (0ï¼100 points) at the ends of the 2nd and 4th week as well as the 6th month after the treatment. If the shoulder pain disappeared or basically disappeared, it was considered to be healed. If the pain was relieved, it was considered to be effective. Otherwise, it was considered to be ineffective. RESULTS: At the ends of the 2nd and 4th week as well as the 6th month after the treatment, the VAS scores of the IHTANï¼acupoint injection group were significantly lower than those of the warm needle moxibustionï¼acupoint injection and acupoint injection groups (P<0.05), and the FMA and ADL scores were significantly higher in the IHTANï¼acupoint injection group than in the other two groups (P<0.05). No significant differences were found between the warm needle moxibustionï¼acupoint injection and the acupoint injection groups in the scores of VAS, FMA and ADL (P>0.05). Of the 29, 30 and 29 cases in the warm needle moxibustionï¼acupoint injection, acupoint injection and IHTNAï¼acupoint injection groups, 1, 0 and 7 cases at the 2nd week, 3, 2 and 12 cases at the 4th week, 4, 2 and 15 cases at the 6th month were cured; 15, 14 and 16 cases at the 2nd week, 17, 17 and 13 cases at the 4th week, and 18, 18 and 12 cases at the 6th month experienced marked improvement; 13, 16 and 6 cases at the 2nd week, 9, 11 and 4 cases at the 4th week, 7, 10 and 2 cases at the 6th month had no apparent changes in their shoulder pain severity, with the total effective rates at the 4th week and 6th month being 68.97% and 75.86%, 63.33% and 66.60%, and 86.21% and 93.10%, respectively. CONCLUSION: The internal heat-type acupuncture needle therapy combined with O3 acupoint injection has obvious short-term and long-term therapeutic effects for post-stroke shoulder pain and is obviously superior to warm needle moxibustionï¼ acupoint injection and simple acupoint injection in relieving shoulder pain and improving upper limb motion function.

BACKGROUND: Human epidermal growth factor receptor 2 (HER2) initiates a variety of signals that lead to the invasion and metastasis of gastric cancer. Though drugs targeting HER2 have been applied in clinical practice, drug resistance remains a big challenge. This study aimed to propose a new therapeutic target by exploring the regulating pathway of HER2. METHODS: Reverse transcription polymerase chain reaction (RT-PCR), western blot and immunohistochemistry staining were used respectively to detect the expression of HER2, Twist, E-cadherin and Fascin1 in both HER2 knockdown and overexpressed cell lines. Trans-well chamber assay and wound healing assay were used to detect the invasive ability of gastric cancer cells. The correlation between HER2 and Twist was analyzed based on specimens obtained from 118 patients with gastric cancer. RESULTS: HER2 silencing decreased the expression of Twist (P<0.05) and increased the expression of E-cadherin (P<0.05), while the expression of Fascin1 remained unchanged (P>0.05) and the migration and invasion abilities of cancer cells were weakened (P<0.01). On the contrary overexpression of HER2 increased the expression of Twist (P<0.05) and decreased the expression of E-cadherin (P<0.05), while the expression of Fascin1 still remained unchanged (P>0.05), and the migration and invasion abilities of cancer cells were enhanced (P<0.01). Our data indicated that the HER2 kinase domain was not involved in the regulation of Twist or E-cadherin. In addition, the expression of HER2 was positively correlated with the EMT-related transcription factor Twist in gastric cancer tissues. CONCLUSION: HER2 could promote the invasion and migration of gastric cancer cells by down-regulating E-cadherin and up-regulating Twist, which indicated that E-cadherin and Twist were both promising therapeutic targets.
