Effectiveness and Safety of Moxibustion Robots on Primary Dysmenorrhea: A Randomized Controlled Pilot Trial / 中国结合医学杂志

OBJECTIVE@#To conduct a pilot trial to explore the effectiveness and safety of moxibustion robots in treating primary dysmenorrhea (PD) and evaluate its feasibility in clinic.@*METHODS@#A total of 70 participants with PD were allocated to either moxibustion robot (MR) group (35 cases) or manual moxibustion (MM) group (35 cases) using computer-generated randomization. One acupoint Guanyuan (CV 4) was selected to receive moxa heat stimulation. Two groups of participants were given 3 menstrual cycles of MM and MR treatment respectively (once a day, 5 days a session) and received another 3 menstrual cycles follow-up. The degree of pain was evaluated by short-form McGill pain questionnaire (SF-MPQ) and the symptoms of dysmenorrhea were evaluated by Cox Menstrual Symptom Scale (CMSS). The safety was measured by the occurrence rate of adverse events (AEs), including burns (blisters, red and swollen), itching, bowel changes, menstrual cycle disorder, menorrhagia and fatigue, etc. RESULTS: A total of 62 patients completed the trial, 32 in MR group and 30 in MM group. Compared with baseline, scores of SF-MPQ and CMSS significantly decreased in both groups (P0.05). The total occurrence rate of AEs in MR group was 2.1%, which was significantly lower than MM group (7.2%, P<0.05).@*CONCLUSIONS@#MR has the same effect as MM at SF-MPQ and CMSS in patients with PD. However, MR is safer than MM (Trial registration No. ChiCTR1800018236).

Development and application of a moxibustion instrument with multi-jointed manipulator / 中国针灸

In view of the limitations of the existing moxibustion instruments, i.e. possible accidental injury when using moxibustion instruments, the negative effects of products from moxibustion instruments on treatment efficacy and health of medical staff and patients, a moxibustion instrument with multi-jointed manipulator is designed. This moxibustion instrument could accurately control the temperature, maintain a safe moxibustion distance, automatically process the burning ashes of moxa and selectively handle moxa smoke. The experimental results shows that this instrument could maintain the constant temperature of target acupoint, reduce the risk of empyrosis, and reasonably deal with the products of moxibustion. The purification rate of moxa smoke is 44.9%, which not only ensures the therapeutic effect of moxa smoke, but also reduces the negative effects of high-concentration moxa smoke on the health of medical staff and patients.

Expression of Bex1 and NF-kBp65 in tongue squamous cell carcinoma and its significance / 口腔疾病防治

Objective @#To investigate the expression of brain expressed X-linked gene 1(Bex1) and nuclear factor-kBp65 (NF-kBp65) in tongue squamous cell carcinoma, and its significance.@*Methods@# Immunohistochemistry was used to detect the expression of Bex1 and NF-kBp65 in 60 tongue squamous cell carcinoma (TSCC) tissues and adjacent normal tissues, and the relationships between Bex1, NF-kBp65 and the clinicopathological features and prognosis of patients were analyzed.@*Results @#The positive expression rate of Bex1 in TSCC was 48.3% (29/60), which was significantly lower than that in adjacent normal tissues 88.3% (53/60) (x2=22.18, P < 0.01). The positive rate of Bex1 was negatively correlated with TNM stage, and the difference was statistically significant (P < 0.05). The positive rate of 63.3% (38/60) in TSCC was significantly higher than 20% (12/60) in adjacent normal tissues (x2=23.18, P < 0.01), the positive rate of NF-kBp65 was positively correlated with TNM stage, and the difference was statistically significant (P < 0.05). According to the Pearson correlation analysis results, the expression of Bex1 and NF-kBp65 in TSCC tissues was negatively correlated (r=-0.302, P=0.019). Kaplan-Meier survival curves showed that the survival rate of Bex1 positive patients was significantly higher than that of Bex1 negative patients.@*Conclusion @#In TSCC tissues, the low positive expression rate of Bex1 and the high positive expression rate of NF-kBp65 may promote tumor invasion and metastasis, and the negative expression of Bex1 may be related to the poor prognosis of patients.

Analysis of prescription regularity of traditional Chinese medicine for colorectal cancer based on data mining / 中国中药杂志

The tumor prescriptions contained in Dictionary of Tumor Formulas, Compendium of Good Tumor Formulas, Chinese Pharmacopoeia, Ministry of Health Drug Standards for Chinese Medicine Formulas and National Compilation of Standards for Proprietary Chinese Medicines were selected and organized to construct a database for tumor prescriptions, and the data mining techniques were applied to investigate the prescription regularity of colorectal cancer prescriptions. The formula data were extracted after screening in strict accordance with the inclusion and exclusion criteria, and were then analyzed with Microsoft Excel 2010 for frequency statistics, Apriori block provided by SPSS Clementine 12.0 software for correlation rule analysis, and arules and arulesViz packages in R 4.0.2 software for correlation rule visualization. In addition, SPSS 18.0 software was used for cluster analysis and factor analysis, in which cluster analysis was performed by Ochiai algorithm with bicategorical variables in systematic clustering method and factor analysis was performed mainly with principal component analysis. A total of 285 prescriptions were included in the statistical analysis, and the frequency statistics showed that 43 herbs had been used more than 16 times. The association rules analysis showed that 26 high-frequency me-dicine pair rules were obtained, and the association rules for those dispelling evil spirits, strengthening the body, resolving stasis, dispelling dampness, etc. were visualized. In the cluster analysis, we generated a dendrogram from which 7 groups of traditional Chinese medicines with homogeneity were extracted. 10 common factors were obtained in the factor analysis. The types of herbal medicines involved in the colorectal cancer prescription included anti-cancer antidotes, strengthening and tonifying medicines, blood-regulating medicines, and expectorant medicines, corresponding to the treatment for eliminating evil spirits, strengthening, resolving stasis, and expectorating dampness. The prescriptions for anti-cancer detoxification were normally based on the pairs composed of Scutellaria barbata-Hedyotis diffusa and Sophora flavescens, Sargentodoxa cuneata, S. barbata, often combined with stasis relieving drug and dampness eliminating drug, reflecting the characteristics of treatment for both toxicity and stasis, dampness and toxicity simultaneously. The prescriptions for strengthening the righteousness and tonifying the deficiency were composed of Astragalus membranaceus and Atractylodes macrocephala mainly, exerting the effect of benefiting Qi, strengthening the spleen and drying dampness, tonifying kidney and essence, tonifying blood and invigorating blood. Meanwhile, anti-cancer detoxification medicines shall be reduced as much as possible. The compatibility of the medicines for the intestinal tract reflected the principle of using the right medicine for the right condition and eliminating evil spirits or strengthening the body, as appropriate.

Morphological changes in the midface of Beagle dogs treated by trans-sutural distraction / Cambios morfológicos en la cara media de perros Beagle tratados por distracción trans-sutural

Trans-sutural distraction is a biological process that induces the formation of new bone and changes the position of bone by pulling on growing suture under the action of external forces. Currently, therapy to midfacial hypoplasia treated by trans-sutural distraction has been applied. In this study, Beagle dogs were selected as experimental animals, and a traction device designed by ourselves was applied to Beagle dogs to simulate the treatment process of trans-sutural distraction in human face, so as to provide a basis for the subsequent research on the related mechanism of trans-sutural distraction. The objective is that the animal model can provide the basis for the follow-up study of transsutural distraction. 45 month beagle dogs were randomly divided into two groups 3 in experiment group and 3 in control group. Implant nails were implanted as the bone marker in the bilateral zygomatic temporal suture, zygomandibular maxillary suture and palatine transverse suture in experimental group. The traction of the maxilla was carried out by the external cranial traction frame with canine fossa as bearing point, 800g force each side, elastic traction for 15 days. The control group only implanted the implant nail as the bone marker on both sides of the bone suture. The distance between two implant nails was measured by vernier calipers and X-ray examination, compared with preoperative and postoperative changes. X-ray and cephalometric measurements were used to measure change in the cranial basal angle. HE staining was used to observe the width of the bone seams, the morphology and structure of the cells and the tissue of the new bone under the phase contrast microscope. Then descriptive statistical analysis and t-test between two independent samples are carried out for the measurement data. The experimental group had a good retention of the beagle traction frame. In the experimental group, the maxillaries of dogs were protrudent in the process of traction gradually and the occlusal relationship changed to type II malocclusion. When the traction is 15 days, the coverage distance is about 8~9 mm. Before and after the traction, the distance between landmark points indicated that the spacing between the transverse palatine suture was the largest (experimental group: 5.52±0.19 mm control group 1.31±0.06 mm P<0.05), and zygomaticotemporal suture was the second (experimental group: 3.12±0.15 mm, control group 0.73±0.04 mm, P<0.05), and zygomaticomaxillary suture was less (experimental group: 2.60±0.34 mm, control group 0.53±0.05 mm, P<0.05). The cranial basal angle was no change before and after operation (controlgroup: 32.3±1.3°, experimental group: 33.2±1.1° P>0.05. Histology showed that the collagenous fibers in the suture of the control group were denser and the osteoblasts were visible on the edge of the suture, showing osteogenic activity. The experimental group significantly widened suture (experimental group: 1209.388±42.714 µm, control group 248.276±22.864 µm, P<0.05), the number of fibroblasts increased significantly with loose collagen fiber. The direction of cell and fiber arrangement were parallel to the traction force. There were many small blood vessels and marrow cavities, and the bone trabecula around the bone suture was thin (experimental group: 23.684±3.774 mm, control group: 86.810±9.219 mm, P < 0.05), showing active osteogenic activity. The growing beagle dog can be used to establish a suture traction animal model for experimental study. In the experiment, Kirschner wire was used to penetrate the bottom plane of the piriform hole of the maxilla (about the position of the canine fossa at the back) and the traction direction was basically the same as the growth direction, and the maxilla was basically parallel and moved forward.

La distracción trans-sutural es un proceso biológico que induce la formación de hueso nuevo y cambia la posición del éste al tirar de la sutura en crecimiento bajo la acción de fuerzas externas. Actualmente, se ha aplicado la terapia para la hipoplasia de la cara media tratada por distracción trans-sutural. En este estudio, fueron seleccionados perros Beagle como animales experimentales, y un dispositivo de tracción fue instalado a los perros para simular el proceso de tratamiento de la distracción trans-sutural en el rostro humano. El objetivo fue proporcionar una base para la investigación posterior sobre mecanismos relacionados con la distracción trans-sutural. El modelo animal puede proporcionar la base para este tipo de estudio de seguimiento de la distracción trans-sutural. Perros Beagle de 45 meses de edad se dividieron aleatoriamente en dos grupos: 3 en el grupo experimental y 3 en el grupo control. Los clavos de implante se usaron como marcadores óseos en la sutura temporal cigomática bilateral, la sutura maxilar cigomandibular y en la sutura transversal palatina en el grupo experimental. La tracción del maxilar se realizó mediante el marco de tracción craneal externo con fosa canina como punto de apoyo, 800 g de fuerza a cada lado, tracción elástica durante 15 días. En el grupo control solo se implantó el clavo del implante como marcador óseo en ambos lados de la sutura. La distancia entre dos clavos de implante se midió mediante calibradores de vernier y examen de rayos X, en comparación con los cambios preoperatorios y postoperatorios. Se utilizaron mediciones cefalométricas y de rayos X para medir el cambio en el ángulo basal craneal. La tinción con HE se usó para observar el ancho de las suturas óseas, la morfología y la estructura de las células y el tejido del hueso nuevo bajo el microscopio de contraste de fase. Luego se realizó un análisis estadístico descriptivo y una prueba t entre dos muestras independientes para los datos de medición. El grupo experimental tuvo una buena retención del cuadro de tracción del Beagle. En el grupo experimental, los maxilares de los perros sobresalieron gradualmente en el proceso de tracción y la relación oclusal cambió a maloclusión tipo II. Cuando la tracción era de 15 días, la distancia de cobertura fue de aproximadamente 8 ~ 9 mm. Antes y después de la tracción, la distancia entre los puntos de referencia indicaba que el espacio entre la sutura palatina transversal era más grande (grupo experimental: 5,52 ± 0,19 mm, grupo de control 1,31 ± 0,06 mm, P <0,05), y la sutura cigomáticotemporal fue la segunda. (Grupo experimental: 3,12 ± 0,15 mm, grupo control 0,73 ± 0,04 mm, P <0,05), y la sutura cigomaticomaxilar fue menor (grupo experimental, 2,60 ± 0,34 mm, grupo control 0,53 ± 0,05 mm, P <0,05). El ángulo basal craneal no cambió antes ni después de la operación (grupo control 32,3 ± 1,3, grupo experimental, 33,2 ± 1,1 ° , P> 0,05). La histología mostró que las fibras colágenas en la sutura del grupo control eran más densas y los osteoblastos se observaron en el margen de la sutura, mostrando actividad osteogénica. En el grupo experimental se amplió significativamente la sutura (1209,388 ± 42,714 µm, grupo control 248,276 ± 22,864 µm, P <0,05), el número de fibroblastos aumentó significativamente con fibras colágenas dispersas. La dirección de la disposición de la celda y las fibras era paralela a la fuerza de tracción. Se observó gran cantidad de vasos sanguíneos pequeños, cavidades medulares, y trabéculas óseas alrededor de la sutura ósea (grupo experimental: 23,684 ± 3,774 mm, grupo control: 86,810 ± 9,219 mm, P <0,05), que mostró actividad osteogénica activa. El perro Beagle en crecimiento se puede utilizar para estudios experimentales y así establecer un modelo animal de tracción de sutura. En el proceso, se usó alambre de Kirschner para penetrar en el plano inferior del foramen piriforme del maxilar (aproximadamente en la posición de la fosa canina en la parte posterior) y la dirección de tracción fue básicamente la misma que en el crecimiento.

Benzyl isothiocyanate inhibits invasion and induces apoptosis via reducing S100A4 expression and increases PUMA expression in oral squamous cell carcinoma cells

Benzyl isothiocyanate (BITC) has been shown to inhibit invasion and induce apoptosis of various types of cancer. However, its role on human oral squamous cell carcinoma (OSCC) cells is still not well elucidated. In the present study, we investigated the effect of BITC on apoptosis and invasion of SCC9 cells, and its underlying mechanisms in vitro and in vivo. SCC9 cells were exposed to BITC (5 and 25 μM) for 24 and 48 h. Cell growth, apoptosis, invasion, and migration were detected in vitro by MTT, FITC-conjugated annexin V/propidium iodide staining followed by flow cytometry, Matrigel-coated semi-permeable modified Boyden, and wound-healing assay. S100A4, PUMA, and MMP-9 expressions were detected to investigate its mechanisms. Xenotransplantation experiments were used to investigate the role of BITC on tumor growth and lung metastasis. BITC inhibited cell viability and induced cell apoptosis in a dose- and time-dependent manner through upregulation of PUMA signals. BITC inhibited cell invasion and migration by downregulation of S100A4 dependent MMP-9 signals. The ip administration of BITC reduced tumor growth but not lung metastasis of SCC9 cells subcutaneously implanted in nude mice. BITC treatment activated pro-apoptotic PUMA and inhibited S100A4-dependent MMP-9 signals, resulting in the inhibition of cell growth and invasion in cultured and xenografted SCC9 cells. Thereby, BITC is a potential therapeutic approach for OSCC.

Professor -'s experiences in treatment of intellectual disability with acupuncture at " line" is summarized. In the pathogenesis of intellectual disability, the insufficiency of essential and the malnutrition of the prenatal essence and the postnatal essence result in the insufficiency of of five organs. Persistent sickness consumes and injures blood. The insufficiency of and blood causes the dysfunction of transportation and transformation. Hence, phlegm is produced and mixed with stasis. This disease is localized in the brain and closely related to heart, kidney, spleen and stomach. The " line" was created on the base of the theory of street and the international standard of scalp acupuncture. The satisfactory effect has been achieved in the children with intellectual disability treated by this therapeutic method. In clinical treatment, the syndrome differentiation of the disease should be integrated with the symptoms.

Oral health status in children with acute lymphoblastic leukemia / 口腔疾病防治

Objective@#To provide basic data for the prevention of oral diseases in children with acute lymphoblastic leukemia (ALL) by investigating the oral health status.@*Methods@#Seventy-three children diagnosed with ALL and seventy-three healthy controls participated in the study. Oral examinations were carried out for both groups. The crown caries were analyzed by calculating the incidence of caries, mean caries and dental caries filling rate; the soft scale index (debris index, DI) and plaque index (plaque index, PLI) were used to record oral hygiene status; and the modified gingival index (modified gingival index, MGI) was used to record gingival health status. A questionnaire was given to the parents at the same time. The data were collected and analyzed with SPSS 20.0 software.@*Results@#① The average numbers of decayed teeth in the observation and control groups were 1.34 ± 171 and 1.15 ± 1.67, respectively. The caries prevalence were 52.05% and 41.10%, but there was no significant difference between the two groups (P>0.05). The obturation rate of caries was 6.12% and 20.24%, and the difference between the two groups was significant (P = 0.001). ② The DI, PI and MGI of the observation group were higher than those in control group, and the differences were significant (P< 0.05). ③ There was a mean of 1.21 ± 1.70 caries in male children and 1.47 ± 1.75 in female children; there was no significant difference between the two groups (P>0.05). The< 6 years old group had a mean of 1.65 ± 1.92 caries and that of the 6~14 group was 0.71 ± 0.95; the difference was significant (P< 0.05). The urban group and rural group had means of 0.87 ± 1.31 and 1.69 ± 1.91 caries, respectively, and the difference was significant (P< 0.05). Children who brushed their teeth and strictly controlled their sweets had significantly fewer mean caries than did those who did not brush their teeth and ate more sweets, and the difference was statistically significant (P< 0.05). ④ The DI, PLI and MGI were significantly different between different age groups and different places of residence (P< 0.05).@*Conclusion @# The oral health status of children with ALL was poorer than that of normal children; oral hygiene was not maintained. Thus, more attention must be paid to the prevention and control of caries and periodontal diseases among children with ALL.
