ObjectiveTo explore the possible pathogeny of tension headache(TH) as well as some emotional and cognitive function impediment.Methods53 cases with tension headache were given coronal CT or MRI examination and cervix X-ray examination.Self-Rating Anxiety Scale(SAS),Self-Rating Depression Scale(SDS) and Mini-Mental State Examination(MMSE) were used to assess their emotion and cognition.ResultsThere were 14 cases of magnitude mental events induced anxiety and/or depression,23 cases of work tensions induced anxiety,14 cases of work tensions induced depression,and 12 cases of lightly cognitive impediment.ConclusionTension headache patients usually related with continued convulsion of cervical muscle induced by hard work and life.Most of them represent more or less emotional impediment,part of them represent lightly cognitive impediment.

Clinical transplantation evidence has indication that umbilical cord blood (UCB) can be useful in the hematopoietic reconstitution in the children, but not well in the adult patients because of the low cell count. The purpose of our study was to evaluate a new method for collection of blood cells from human placenta and umbilical cord. We have simultaneously harvested blood cells from umbilical cord (UCB), placenta blood (UPB) and placenta tissue (UPT) for their content of nucleated cells, CD34 (hematopoietic stem progenitor marker) positive cells. Result showed that the nuclear cell (NC) from UPB and UPT has three to four times than that from umbilical cord blood only, (8.3 +/- 1.04) x 10(8) (UCB), (16.33 +/- 5.54) x 10(8) (UPB), and (8.01 +/- 2.64) x 10(8) (UPT). CD34(+) cells are (0.77 +/- 0.01) x 10(6), (1.25 +/- 0.55) x 10(6) and (4.21 +/- 1.90) x 10(6) respectively. The cells from UPB and UPT have more survival ability than the cells from UCB in the long-term cell culture condition. It is clear that the blood stored in the liquid nitrogen did not show large loss of total nucleated cell count and CD34(+) cells. It was observed that UPT and UPB contained more suppressor lymphocytes, which may be important in prevention of graft-versus-host disease. In conclusion, our data may have implications for the development of placental blood collection together with umbilical cord blood banking for the stem cell transplantation.

The combination of Glycyrrhizae Radix et Rhizoma and Aconiti Lateralis Radix Preparata can increase efficacy and decrease toxicity. This study started from the phenomena of protein self-assembly in the mixed decoction of Glycyrrhizae Radix et Rhizoma with Aconiti Lateralis Radix Preparata. The attenuated mechanism was explored between the combination of Glycyrrhizae Radix et Rhizoma and Aconiti Lateralis Radix Preparata by using the protein of Glycyrrhizae Radix et Rhizoma and aconitine which was the major toxic component of Aconiti Lateralis Radix Preparata. Glycyrrhizae Radix et Rhizoma protein with aconitine could form stable particles which particle mean diameter was (206.2 ± 2.02) nm and (238.20 ± 1.23) nm at pH 5.0 in normal temperature. Through the mouse acute toxicity experiment found that injection of aconitine monomer all mice were killed, and injection of Glycyrrhizae Radix et Rhizoma protein-aconitine particles with the same content of aconitine all mice survived. Survey the stability of Glycyrrhizae Radix et Rhizoma protein-aconitine shows that the colloid particles is stable at room temperature, and it has the possibility to candidate drug carrier. Glycyrrhizae Radix et Rhizoma protein can reduce the toxicity of aconitine through self-assembly.

Seven meroterpenoids and five small-molecular precursors were isolated from Penicillium sp., an endophytic fungus from Dysosma versipellis. The structures of new compounds, 11beta-acetoxyisoaustinone (1) and isoberkedienolactone (2) were elucidated based on analysis of the spectral data, and the absolute configuration of 2 was established by TDDFT ECD calculation with satisfactory match to its experimental ECD data. Meroterpenoids originated tetraketide and pentaketide precursors, resepectively, were found to be simultaneously produced in specific fungus of Penicillium species. These compounds showed weak cytotoxicity in vitro against HCT-116, HepG2, BGC-823, NCI-H1650, and A2780 cell lines with IC 50 > 10 micromol x L(-1).

Purpose: We evaluated the therapeutic effects on overactive bladder (OAB) symptoms and sexual function of behavioral therapy with or without mirabegron in sexually active male patients with OAB. Mirabegron, a selective β3 adrenoceptor agonist for the treatment of OAB, has been shown to induce corpus cavernosum relaxation. Methods: In this 4-site, randomized controlled trial, 150 sexually active men with OAB were enrolled between June 2020 and May 2022. Participants were randomly allocated (1:2) into 2 treatment groups: (1) behavioral therapy alone (n = 50) and (2) a combination of mirabegron 50 mg daily and behavioral therapy (n = 100). The evaluation was based on the overactive bladder symptoms score (OABSS), the International Index of Erectile Function, the ejaculatory domain short form, the International Prostate Symptom Score, patient perception of bladder condition, quality of life, and urodynamic parameters. The therapeutic outcomes were assessed at baseline, 4 weeks, and 12 weeks. Results: There were 65 patients (65%) in the combination subgroup and 36 patients in the behavioral therapy who completed all 12 weeks of treatment. Both groups had a statistically significant improvement in OABSS after 12 weeks of treatment. The combination therapy group achieved a statistically significant improvement in all 4 subscores of OABSS, however, the urinary frequency (P = 0.120) and urinary incontinence (P = 0.234) subscores in the behavioral therapy only group did not show a significant change. Additionally, the combination group had a significant improvement in functional bladder capacity, which was not seen in the behavioral therapy group. However, both groups did not have a significant change in erectile or ejaculatory function. Conclusions Behavioral therapy combined with mirabegron had more significant impact on the improvement of OAB than behavior therapy alone. However, both groups did not have significant changes in erectile or ejaculatory function.

Through analysis on sequencing of meridians and their muscle regions, their pertaining organs, run ning courses, linking and indications described in Zubi Shiyimai (Eleven Meridian of Foot and Hand), Yinyang Shiyimai (Eleven Meridian of Yinyang), Lingshu: Jingmai (Miraculous Pivot: Meridian) and Lingshu: Jinjing (Miraculous Pivot: Muscle Meridian), it is found that most of the indications of acupuncture in ancient time are symptoms of the muscle regions. 62.59% points of the national standard acupoints location close to tender points of the muscle regions, which indicates that the origin of early acupoints are tender points along the running courses of the muscle regions. Thus, it is concluded that meridians and their muscle regions have the same origin, which provides new train of thinking for a better comprehension of origin of meridians and collaterals.

OBJECTIVETo establish the three-dimensional finite element model of calcaneus, and to discuss mechanism of calcaneal fracture.

METHODSThe calcaneus of normal person was scanned with spinal CT, and the finite element model was established with the Sap 93 software. The node and element number of this model was 1 959 and 1 496 respectively. After establishing the finite element model of the calcaneus, the axial load of 500 N was applied on the model in neutral position and back stretches 20 degree position. The stress distribution and the displacement of the models were observed.

RESULTSThe fracture line passed through the lateral articular facet of talocalcaneal joint when the ankle joint was in neutral position, and the stress distribution was maximal at calcaneus from posteromedial to anterolateral aspect. In addition, the stress distribution was maximal from calcaneus to position between posterior talar articular surface and calcaneal tendon when the ankle joint was in back stretch position of 20 degree.

CONCLUSIONWhen falling down, the fracture line will pass through the facet of talocalcaneal joint from lateral to posteromedial side if the ankle joint was in neutral position; and the line will through pass the calcaneus body to post spinula joint, as well as avulsion fracture of calcaneal tendon occurred if the ankle joint was in back stretch position of 20 degree.

OBJECTIVETo investigate the potential of renal pathological index as a differential diagnosis factor for Chinese medicine (CM) syndromes typing in IgA nephropathy (IgAN).

METHODSA total of 1,016 patients with IgAN was recruited from November 2001 to November 2004. All the signs and symptoms including picture of the tongue and pulse tracings were collected. All patients were typed according to the CM syndrome typing scheme for chronic primary glomerulopathy. The severity of glomerulus and tubulointerstitial lesions (mild, moderate-severe) were evaluated using lee's grading system and the Katafuchi score system.

RESULTSThe syndrome types transform in turn by deficiency of both the Spleen (Pi) and Lung (Fei) qi, deficiency of both qi and yin, deficiency of Liver (Gan) and Kidney (Shen) yin and deficiency of Spleen-Kidney (Shen) yang, with the aggravation of pathogenetic condition and that the manifestation of deficiency of qi clinically showed proliferative lesion of glomerular mesangium, while the glomerular sclerosis pathologically showed the manifestation of yin deficiency.

CONCLUSIONRenal pathological findings may be a candidate of objective factors to refine CM syndrome typing process.

Naringenin (1) was transformed to three metabolites (2-4) by Mucor sp. Based on LCMS(n)-IT-TOF and NMR spectroscopic data, 2-4 were identified as naringenin-7-O-sulphate, naringenin-4'-O-sulphate, and naringenin-5-O-sulphate, respectively. These results might provide hints to the mammalian/human metabolism of naringenin.
