OBJECTIVE@#To compare the clinical efficacy between wrist-ankle acupuncture and conventional acupuncture on shoulder-hand syndrome (SHS) phaseⅠafter stroke.@*METHODS@#A total of 64 patients with SHS phaseⅠafter stroke were randomized into a wrist-ankle acupuncture group and a conventional acupuncture group, 32 cases in each group. On the basis treatment of internal medicine and conventional rehabilitation, wrist-ankle acupuncture was applied at upper 4 area, upper 5 area and upper 6 area on the affected side in the wrist-ankle acupuncture group, while acupuncture was applied at Jianyu (LI 15), Quchi (LI 11), Shousanli (LI 10), etc. on the affected side in the conventional acupuncture group. The treatment was given 30 min each time, once a day, 5 days a week for 3 weeks in both groups. Before and after treatment, the visual analogue scale (VAS) score, degree of hand swelling, shoulder-hand syndrome scale (SHSS) score, Fugl-Meyer assessment for upper extremity (FMA-UE) score and modified Barthel index (MBI) score were observed, and the clinical therapeutic effect was evaluated in both groups.@*RESULTS@#After treatment, the VAS scores, degree of hand swelling and SHSS scores were decreased (P<0.05), and the FMA-UE scores and MBI scores were increased (P<0.05) compared before treatment in both groups; in the wrist-ankle acupuncture group, the VAS score, degree of hand swelling and SHSS score were lower (P<0.05), and the FMA-UE score and MBI score were higher (P<0.05) than those in the conventional acupuncture group. The total effective rate was 96.9% (31/32) in the wrist-ankle acupuncture group, which was superior to 90.6% (29/32) in the conventional acupuncture group (P<0.05).@*CONCLUSION@#Wrist-ankle acupuncture can effectively relieve pain and hand swelling, improve motor function of upper extremity and self-care ability of daily life in patients with shoulder-hand syndrome phaseⅠafter stroke, the therapeutic effect is superior to conventional acupuncture.

Inhibitory effects of recombinant porcine interferon-α on porcine transmissible gastroenteritis virus infections in TGEV-seronegative piglets.

Our previous research obtained purified recombinant porcine interferon-α (rPoIFN-α) containing thioredoxin (Trx) fusion tag in E. coli Rosetta (DE3). Here, we evaluate the efficacy of this rPoIFN-α to prevent piglets from the infection of the transmissible gastroenteritis virus (TGEV) attack. In this experiment, twenty-five TGEV-seronegative piglets were randomly divided into five groups. Group 1 was positive control and only challenged with TGEV; Pigs in groups 2-4 were pretreated with 2 × 10(7)IU/pig, 2 × 10(6)IU/pig, and 2 × 10(5)IU/pig rPoIFN-α before TGEV challenge. The fifth group is a negative control group. The animals of this group are pretreated only with Trx protein-containing PBS solution without TGEV challenge. After 48 h of rPoIFN-α pretreatment, the pigs in groups 1-4 were challenged by TGEV, and the pigs in group 5 were administered with PBS. The surveillance results show that Pigs pre-treated with 2 × 10 (7) IU/pig rPoIFN-α are fully aligned with the violent TGEV attack. Pigs pretreated with 2 × 10 (6) IU/pig rPoIFN-α are partially aligned with the violent TGEV attack. Though piglets pretreated with 2 × 10(6) IU/pig or 2 × 10(5)IU/pig rPoIFN-α cannot be adapted to the challenge of TGEV. However, the use of this dose of rPoIFN-α could put off the clinical signs of pigs than the positive control group of the above. These results indicate that rPoIFN-α can protect pigs from the infection of potential TGEV or delay the appearance of clinical symptoms, and its effect is dose-dependent.

Endoscopic ultrasonography is useful in the diagnosis and treatment of rectal neuroendocrine neoplasms: a case series.

Rectal neuroendocrine neoplasms (NENs) are low-grade malignancies, which are slow-growing and usually become symptomatic late in the course of the disease (Basuroy et al., 2016). In recent years, rectal NENs are increasingly frequently detected, with the widespread availability and accessibility of endoscopy and cross-sectional imaging modalities (Kos-Kudla et al., 2017). Multiple studies have shown that endoscopic ultrasound (EUS) is an advanced endoscopic technique and is currently used in the diagnosis and preoperative assessment of NENs (Kim, 2012; Liu et al., 2013; Zhang et al., 2017). However, EUS imaging of rectal NEN and differential diagnosis with other submucosal tumors (SMTs) has not been adequately reported. In this study, we reviewed and summarized the EUS imaging and pathological features of rectal NENs of 38 cases to improve preoperative diagnosis rate and reduce unreasonable treatment.

Recent development in hypertension gene study / 中国实用内科杂志

Genetic as well as genomic study has advanced the development of precision medicine. We are marching on the road for right patients who are receiving more and more right treatment at right time. In hypertension field, precision medicine is available, actionable and affordable. First and the most practical advancement is monogenic hypertension, the disease-genes have been found for at least 17 types of monogenic hypertension. These patients can be precisely treated according to their carried gene mutation. Secondly, pharmacogenetic and pharmacogenomic guided anti-hypertensive drug selection, very promising but lack of clinic outcome data to support widely clinical application. Majority of hypertension are due to multiple genetic and environmental factors. GWAS fund some genetic variants related to primary hypertension, but these variants can only be responsible for 1-10% of blood pressure variation. We have a long way to go in exploring the real cause of primary hypertension.

Placental site nodule: a clinicopathological study of 20 cases / 临床与实验病理学杂志

Purpose To investigate the clinical manifesta-tions and morphologic features of placental site nodules (PSNs), and its clinical significance. Methods Twenty patients diag-nosed as PSNs were collected, then a retrospective analysis was conducted, and the characteristics of clinical data and follow-up results were analyzed,including of clinical manifestations, ultra-sonographic evaluation, morphologic and immunohistochemical features. Results The age of patients ranged from 25 to 41 years (32. 48 ± 4. 77 years in average). Three fifths of patients had pregnancy history for at least two times and the interval time to the last pregnancy ranged from 5 to 37 months (15. 33 ± 8. 05 months on average). 15 (75% ) patients went to the hospital because of abnormal vaginal bleeding. In our study, most of the samples showed a membrane-like structure without definite nod-ule. Microscopically, single or multiple, well-circumscribed and oval small nodules were found in endometrial tissue. In most ca- ses, the hyalinization was generally uniform in the center of the nodules, more or less intermediate trophoblasts appeared on the edge of the nodules. Immunohistochemically, the strong diffuse expressed CK (AE1/AE3), CAM5. 2, EMA, GATA-3, Cyclin E and p63 were detected in most of all cases, and PLAP showed strong focal expression, α-inhibin and hPL showed faint focal expression, Ki-67 staining for proliferative index was less than 4% . Conclusion PSN is a benign lesion of the intermediate trophoblast at the chorionic leave. Some diseases including hya-linized decidua, epithelioid trophoblastic tumor, and squamous cell carcinoma with hyalinization need to be identified. Some im-munohistochemical markers may be certain helpful in distinguis-hing as necessary.

Formulation of dried lignans nanosuspension with high redispersibility to enhance stability, dissolution, and oral bioavailability / 中国天然药物

Herpetospermum caudigerum lignans (HTL), one of the potential drugs with anti-hepatitis B virus and hepatoprotective effects, has limited clinical applications because of poor aqueous solubility and low bioavailability. Both herpetrione (HPE) and herpetin (HPN) are the most abundant ingredients in HTL and exhibit weak acidity. The purpose of the present study was to produce dried preparations of HTL (composed of HPE and HPN) nanosuspensions (HTL-NS) with high redispersibility using lyophilization technology. The HTL-NS was prepared by utilizing precipitation-combined homogenization technology based on acid-base neutralization reactions, and critical formulation and process parameters affecting the characteristics of HTL-NS were optimized. The resultant products were characterized by particle size analysis, SEM, XRD, stability, solubility, dissolution and in vivo bioavailability. HTL-NS showed near-spherical-shaped morphology and the size was 243 nm with a narrow PDI value of 0.187. The dried preparations with a relatively large particle size of 286 nm and a PDI of 0.215 were achieved by using 4% (W/V) mannitol as cryoprotectants, and had a better stability at 4 or 25 °C for 2 months, compared to HTL-NS. In the in vitro test, the dried preparations showed markedly increased solubility and dissolution velocity. Besides, in the in vivo evaluation, it exhibited significant increases in AUC, CMRT and a decrease in T, compared to the raw drug. In conclusion, our results provide a basis for the development of a drug delivery system for poorly water-soluble ingredients with pH-dependent solubility.

Centralized isolation of Helicobacter pylori from multiple centers and transport condition influences.

AIM: To evaluate the efficacy of centralized culture and possible influencing factors. METHODS: From January 2010 to July 2012, 66452 patients with suspected Helicobacter pylori (H. pylori) infection from 26 hospitals in Zhejiang and Jiangsu Provinces in China underwent gastrointestinal endoscopy. Gastric mucosal biopsies were taken from the antrum for culture. These biopsies were transported under natural environmental temperature to the central laboratory in Hangzhou city and divided into three groups based on their transport time: 5, 24 and 48 h. The culture results were reported after 72 h and the positive culture rates were analyzed by a χ (2) test. An additional 5736 biopsies from H. pylori-positive patients (5646 rapid urease test-positive and 90 (14)C-urease breath test-positive) were also cultured for quality control in the central laboratory setting. RESULTS: The positive culture rate was 31.66% (21036/66452) for the patient samples and 71.72% (4114/5736) for the H. pylori-positive quality control specimens. In the 5 h transport group, the positive culture rate was 30.99% (3865/12471), and 32.84% (14960/45553) in the 24 h transport group. In contrast, the positive culture rate declined significantly in the 48 h transport group (26.25%; P < 0.001). During transportation, the average natural temperature increased from 4.67 to 29.14 °C, while the positive culture rate declined from 36.67% (1462/3987) to 24.12% (1799/7459). When the temperature exceeded 24 °C, the positive culture rate decreased significantly, especially in the 48 h transport group (23.17%). CONCLUSION: Transportation of specimens within 24 h and below 24 °C is reasonable and acceptable for centralized culture of multicenter H. pylori samples.

Bioassay for enrich-blood bioactivity of Agelicae Sinensis Radix / 中国中药杂志

Danggui, Agelicae Sinensis Radix, is a widely used Chinese herb to enrich blood, but its quality cannot be effectively assessed by the known chemical markers such as ferulic acid, ligustilide, polysaccharides, etc. A new bioassay was therefore developed to quantify the Enrich-Blood Bioactivity (EBB) for the quality assessment of Danggui raw materials. Danggui sample was first extracted with ethanol and water, respectively. Then the ethanolic extract and water extract were mixed as a test sample to quantify the amount of EBB by mice experiment. The blood deficiency mode in mice was developed by intraperitoneal injecting cyclophospharmide and phenylhdrazine hydrochloride. The quantity of red blood cell was chosen as EBB marker. Cyclosporine A was chosen as a control substance. EBB in analytes was quantified by the amount reaction of parallel line analysis (3, 3') method. The results indicated that the reliability test for quantifying EBB was passed through and the measured value was valid. The analytes showed the significant EBB (P < 0.05). The correlation coefficient was 0.9984 (n=5) between the amount of cyclosporine A (0.035-0.56 g x kg(-1)) and the increased number of red blood cell. The relative standard deviation (RSY) on the amount of EBB was estimated to be 6.15% (n = 6) by six replicated tests, and the confidence limit rate was 26.68% (n = 6). Five Danggui samples, which were collected from different cultivation areas with various morphological characters, showed the variety of EBB in the range of 21.95-44.16 U x g(-1). It is concluded that the developed method is accurate to quantify the EBB of Danggui raw materials, and is therefore suitable to assess its quality.

Rat intestine absorption kinetics study on cucurbitacin B-sodium deoxycholate/phospholipid mixed nanomicelles with in vitro everted gut sacs model / 中国中药杂志

To investigate the absorption kinetics of Cu B-SDC/PLC-MMs in rat different intestinal segments and compared with the absorption of Cu B suspension. The in vitro everted gut sacs model was established to study the absorption characteristics of Cu B-SDC/ PLC-MMs in rat duodenum, jejunum, ileum and colon, and the content of cucurbitacin B was detected by HPLC method, and the effects of concentrations on intestinal absorption were evaluated as well. The results showed that the absorption of Cu B-SDC/PLC-MMs was linearity at different intestine segment and different concentrations (R2 > 0.9), which was consistent with zero order rate process. The Ka of different intestine segments showed a concentration-dependent increasing along with the raised concentration of Cu B-SDC/ PLC-MMs, indicating that it was likely to be a mechanism of passive absorption. The best absorption site of Cu B-SDC/PLC-MMs was ileum, and its absorptions in different intestinal segments were superior to cucurbitacin B suspension. SDC/PLC-MMs could significantly enhance the intestinal absorption of cucurbitacin B, and the study of intestinal absorption kinetics of Cu B-SDC/PLC-MMs had gave a support to its further reasonable solidfication.

[Effect of acupuncture intervention on airway remodeling and transforming growth factor-beta1 expression in asthma rats].

OBJECTIVE: To observe the effect of acupuncture stimulation of "Dazhui" (GV 14), bilateral "Fengmen" (BL 12) and "Feishu" (BL 13) on the thickness of the bronchial tubal wall and smooth muscle and expression of transforming growth factor-beta1 (TGF-beta1) in asthma rats so as to reveal its mechanism underlying improvement of asthma. METHODS: Forty SD rats were randomly assigned to control, model, acupuncture and medication groups. The asthma model was induced by subcutaneous injection of 1% egg albumin solution and forced inhalation of atomized ovalbumin. Rats of the acupuncture group were treated by acupuncture stimulation of GV 14, bilateral BL 12 and BL 13 (once daily for 10 days), and rats of the medication group treated by intraperitoneal injection of Aminophylline Injection (100 mg/kg, once daily for 10 days). The thickness of the bronchial tubal wall and airway smooth muscle of the lung tissue were measured by image analyzer for assessing the degree of airway remodeling. The expression of TGF-beta1 in the small airway was detected by immunohistochemistry. RESULTS: Compared to the control group, the thickness of the airway wall and smooth muscle, and the expression level of TGF-beta1 were remarkably increased in the model group (P < 0.01). After acupuncture intervention and medication treatment, the thickness of the airway wall and smooth muscle, and the expression level of TGF-beta1 were remarkably down-regulated in both groups in comparison with those of the model group (P < 0.05, P < 0.01), and the expression of TGF-beta1 in the acupuncture group was obviously lower than that of the medication group (P < 0.05). CONCLUSION: Acupuncture stimulation of GV 14, bilateral BL 12 and BL 13 can down-regulate bronchial asthma-induced increase of TGF-[, expression in the lung tissue in asthma rats, which may contribute to its effect in improving airway remodeling.

Comparison on content of ligustilides in different danggui samples / 中国中药杂志

Bioactivity of Danggui is linked to the content of ligustilide, but the relationship between ligustilide with herb shape, cultivating areas and plant species is still unknown. The relationship was investigated by quantifying on the amounts of Z-ligustilide and E-ligustilide by HPLC-DAD-MS method, and then comparing the content of ligustilides (the sum of Z-ligustilide and E-ligustilide) among forty-four various "Danggui" samples containing thirty Chinese Danggui (CDG), six Japanese Danggui (JDG), four Korea Danggui (KDG) and four European Danggui (EDG). Results showed that the content of ligustilides in CDG samples (Angelica sinensis) was in the range of 5.63-24.53 mg x g(-1) with the mean of 11.02 mg x g(-1) (n = 30). Ligustilides amounts were varied among samples cultivated in different areas in China, i. e. 13.90 mg x g(-1) (n = 6) in Yannan, 12.51 mg x g(-1) (n = 6) in Sichuan and 10.04 mg x g(-1) (n = 13) in Gansu. It was also found that ligustilides content was related to the shape, color and fragrance of herb, e. g. the relative larger amount of ligustilides was in the small main root, long rootlet and perfumed sample. Further, ligustilides contents were estimated to be 1.00 mg x g(-1) (n = 6) in JDG samples (A. acutiloba and A. acutiloba var. sugiyamae) and 2.78 mg x g(-1) (n = 2) in EDG samples (lovage root, Levisticum officinale). However, ligustilides could not be detected in the four KDG samples (A. gigas) and two EDG samples (angelica root, A. archangelica). It has been concluded that ligustilide is significant variant among plant species, which may result in the variety of bioactivity and therapeutic effect.

Central composite design-response surface method optimize of fang-bing nasal inhalant from components of traditional Chinese medicine for sedative and sleep aiding / 药学学报

To obtain the optimal preparation technology of Fang-bing nasal inhalant from components of traditional Chinese medicine by central composite design, with an apparatus containing nasal inhalant that simulated the expiration and inspiration of nose, the dissolution in vitro of different optimized inhalant samples designed through central composite design were investigated. The accumulative release of linalool, borneol, menthol was detected with GC. Response surface methodology was used to optimize the conditions of preparation technology by establishing multiple linear regression and second-order quadratic models. Then, deviation was carried out through comparing the observed and predicted values. It was showed that the coefficient of correlation of second-order quadratic model was high. The related coefficient reached 0.999 3, 0.998 0, 0.944 9, separately. The optimum conditions of preparation technology were as following: 84.39% of alcohol concentration, the weight of starch 1.45 g and the weight of carmellose sodium (CMC-Na for short) 1.22 g. The deviations between observed and predicated values showed -0.36%, 1.52%, 2.40%, separately. In this experiment, the established model can describe the good relation between factors and indexes from preparation technology of Fang-bing nasal inhalant and the outcome of prediction is well. This optimal Fang-bing nasal inhalant was used to study its in vivo effect on model rats deprived from sleep and showed sedative and sleep aiding, which will bring an instruction on inhalants of components from traditional Chinese medicine.

Effect of bronchoscopic cryosurgery in twenty-two children with lower airway stenosis / 中华儿科杂志

<p><b>OBJECTIVE</b>To analyze the effect and safety of bronchoscopic cryosurgery in children with lower airway stenosis caused by granulation and fiber hyperplasia.</p><p><b>METHOD</b>Twenty-two patients had undergone bronchoscopic examination and cryosurgery, 18 patients with atelectasis caused by Mycoplasma pneumoniae pneumonia, 2 patients with endobronchial tuberculosis (EBTB), 1 patient with atelectasis caused by granulation tissue after bronchial foreign body, and 1 case who had severe dyspnea, with tracheal stenosis after long-term endotracheal intubation during surgery for heart disease. All the patients under went bronchoscopic cryosurgery for several times, 1 case with severe tracheal stenosis was operated by electric coagulation before cryosurgery. Before and after the treatment, all the patients were evaluated based on clinical symptoms, tracheal lumen by bronchoscopy, chest CT for atelectasis and pulmonary function for tracheal stenosis.</p><p><b>RESULT</b>The patients were treated with cryosurgery for 1-4 times. Sixteen cases were markedly improved, clinical symptoms disappeared completely, no granulation and fiber hyperplasia were found during bronchoscopy, and all the atelectasis were cured. After the treatment, the bronchial lumen diameter of the patient with tracheal stenosis was increased from 2 mm to about 5 mm, the tidal volume increased from 3.0 ml/kg to 8.8 ml/kg. Five cases were effectively improved, the clinical symptoms also disappeared, during bronchoscopy and bronchial alveolar lavage (BAL), no granulation and fiber hyperplasia were found, but some distal bronchial tubes were atresia or narrowed, the lumen was patent, the atelectasis recovered partially. In 1 case the treatment was ineffective, as the clinical symptoms and granulation disappeared, but because almost all distal bronchi were atresia or narrow, the lumen was not patent during BAL, there was no change on chest CT. The total effective rate was 21/22 (95.5%). No severe complications occurred during and after the procedures. All the patient were followed up for 1 - 12 months, no case had recurrence.</p><p><b>CONCLUSION</b>Treatment with bronchoscopic cryosurgery is a safe and effective methods to tracheal stenosis caused by granulation tissue and fiber hyperplasia in children.</p>
