Electroacupuncture combined with lifestyle control on obese nonalcoholic fatty liver disease: a randomized controlled trial / 中国针灸

OBJECTIVE@#To observe the effect of electroacupuncture (EA) combined with lifestyle control on hepatic fat status, hepatic enzymology, glycolipid metabolism and anthropological parameters in patients with obese nonalcoholic fatty liver disease(NAFLD).@*METHODS@#A total of 90 patients with obese NAFLD were randomized into an observation group (45 cases, 4 cases dropped off) and a control group (45 cases, 1 case dropped off). Lifestyle control was implemented in the control group. On the basis of the treatment in the control group, acupuncture was applied at Zhongwan (CV 12), Quchi (LI 11), Shuifen (CV 9), Huaroumen (ST 24), Daheng (SP 15), Guanyuan (CV 4), Qihai (CV 6), etc. EA was provided at Huaroumen (ST 24) and Daheng (SP 15) with dilatational wave, 2 Hz/100 Hz in frequency, 30 min each time, once every other day, 3 times a week. The treatment for 12 weeks was required in both of the two groups. Hepatic fat status [controlled attenuation parameter (CAP) and liver stiffness measurement (LSM)], hepatic enzymology [alanine aminotransferase (ALT), aspartate aminotransferase (AST) and γ-glutamyl transferase (GGT)], glycolipid metabolism and insulin sensitivity [fasting plasma glucose (FPG), fasting serum lisulin (FINS), homeostasis model assessment of insulin resistance (HOMA-IR), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C)] and anthropological parameters [body weight (BW), body mass index (BMI), fat percentage (FP), waist circumference (WC), hip circumference (HC) and waist-to-hip ratio (WHR)] in the two groups were observed before and after treatment.@*RESULTS@#①Compared before treatment, hepatic CAP, LSM, serum ALT, AST and GGT after treatment were obviously reduced in the two groups (<0.05, <0.01). After treatment, CAP and ALT in the observation group were lower than the control group (<0.05). ②Compared before treatment, FINS, HOMA-IR, LDL-C, TC and TG after treatment were obviously reduced in the two groups (<0.05, <0.01),while the levels of HDL-C were increased (<0.05). Compared before treatment, FPG after treatment in the observation group was reduced (<0.05). Compared with the control group, FINS, HOMA-IR, TC and TG in the observation group were lower than those in the control group after treatment (<0.05). ③Compared before treatment, BW BMI, FP, WC, HC, WHR after treatment were obviously reduced in the two groups (<0.01). After treatment, WC and WHR in the observation group were lower than the control group (<0.05).@*CONCLUSION@#Electroacupuncture combined with lifestyle control can effectively treat obese nonalcoholic fatty liver disease, and present better therapeutic effect on hepatic fat status, glycolipid metabolism, insulin resistance, WC and WHR.

Abnormal processing characteristics to basic emotional faces in the early phase in children with autism spectrum disorder / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To explore the recognition ability and abnormal processing characteristics to basic emotional faces in the early phase in children with autism spectrum disorders (ASD).</p><p><b>METHODS</b>Photos of Chinese static faces with four basic emotions (fearful, happy, angry and sad) were used as stimulus. Twenty-five ASD children and twenty-two age- and gender-matched typical developed children (normal controls) were asked to match the emotional faces with words. Event-related potential (ERP) data were recorded concurrently.</p><p><b>RESULTS</b>N170 latencies for total emotion and fearful face in the left temporal region were faster than in the right one in normal controls (P<0.05), but the results were not noted in ASD children. Further, N170 latencies in the left temporal region of ASD children were slower than normal controls for total emotion, fearful and happy faces (P<0.05), and their N170 latencies in the right temporal region were prone to slower than normal controls for angry and fearful faces.</p><p><b>CONCLUSIONS</b>The holistic perception speed of emotional faces in the early cognitive processing phase in ASD children is slower than normal controls. The lateralized response in the early phase of recognizing emotional faces may be aberrant in children with ASD.</p>

Clinical evaluation of the five-digit numerical recording system for classification of cleft lip and palate deformities / 中华口腔医学杂志

<p><b>OBJECTIVE</b>To evaluate the five-digit numerical recording system (LAPAL system) for classification of cleft lip and palate.</p><p><b>METHODS</b>Fourteen young doctors took part in the study after receiving one-hour instruction twice for the LAPAL system. Photographs of 200 cases of untreated cleft lip and palate were used for the evaluation. The diagnostic codes of the patient were recorded and compared with the teacher's standard diagnosis. The basic criterion of the LAPAL system was that the clefts were arranged in five anatomical components in order of right lip (L), right alveolus and primary palate (A), secondary palate (P), left alveolus and primary palate (A), and left lip (L). The degrees of the cleft severity were recorded with Arabic number 0 for the intact, 1 for the subcutaneous or submucous cleft, 2 for clefts smaller than half of a component, 3 for clefts larger than half of a component, 4 for complete clefts.</p><p><b>RESULTS</b>The rate of the diagnostic coincidence was 88% (2475/2800) totally. The higher coincidence appeared in degree 4 of cleft lip and in degree 4 of cleft alveolar and cleft primary palate as 99% (707/714) and 100% (546/546), respectively. The lower coincidence appeared in degree 2 and degree 3 of clefts of the alveolus and primary palate as 70% (98/140) and 82% (103/126), respectively. Among the 17 types of possible cleft combination, 14 types were found in the present study.</p><p><b>CONCLUSIONS</b>The LAPAL system is easily understood and grasped in a short time. Clefts on the border of adjoin degrees may cause confusion in diagnosis. More training or simplified modification is suggested.</p>

An analysis of surgical outcome and influencing factors in patients of congenital basilar invagination with atlantal-axial dislocation: report of 120 cases / 中华外科杂志

<p><b>OBJECTIVE</b>To investigate the surgical outcome and its influencing factors in patients of congenital basilar invagination (BI) with atlanto-axial dislocation (AAD).</p><p><b>METHODS</b>From May 2004 to August 2010, 120 patients who had BI with AAD were surgically treated with direct posterior intraoperative distraction-reduction and fixation technique, 93 patients were successfully followed up by means of questionnaire survey, telephone and clinical evaluation. Pre- and postoperative dynamic cervical X-rays, computed tomographic scans, 3-dimentional reconstruction views and magnetic resonance imaging were performed. Pre- and postoperative Japanese Orthopaedic Association (JOA) score, distance between odontoid tip and Chamberlain's line and atlantodental interval were measured to evaluate the surgical result. Statistical analysis was performed by means of paired t test and Pearson Correlation analysis.</p><p><b>RESULTS</b>There were 93 cases were followed up for 24-99 months with an average of 46.5 months. Until the final follow-up, clinical symptoms were improved in 79 patients (84.9%), and were stable in 7 patients (7.5%) and deteriorated in 4 patients (4.3%). Three patients died postoperatively (3.2%). Patients without intramedullary signal intensity change (ISIC) had better surgical outcome. Patients with compression from anterior odontoid tip and posterior bone margin of occipital foramen had the worst surgical outcome (F = 3.987, P < 0.01). Overall, good decompression and bone fusion were shown on postoperative image in 87 patients (93.5%). There were 3 deaths in this series because of basilar artery thrombosis, posterior fossa hematoma and unknown reasons each.</p><p><b>CONCLUSIONS</b>The direct posterior intraoperative distraction-reduction and fixation technique is an effective simple and safe method for the treatment of BI with AAD. Anterior compression from odontoid tip and posterior compression from bone margin of occipital foramen-atlantal posterior arch play important roles in its developing mechanism. ISIC on MRI is a predictive factor for the worse surgical outcome.</p>

Combined effect of dark and wounding on regeneration potential of Houttuynia cordata Thunb. leaves.

Houttuynia cordata is one of the most potential medicinal and edible wild herb whose resources have decreased sharply due to excessive exploitation. Besides its slow agamic propagation, problems of browning and non-dedifferentiation have prevented the application of micropropagation in H. cordata. Through 4 week pre-culture in darkness and wounding after 1 week pre-culture, the browning rate of leaf explants decreased significantly and resulted in efficient regeneration (20.64 ± 5.94 adventitious buds per explant) on the induction medium. The protocol shall facilitate conservation and commercial cultivation of the endangered species.

Lumbar MR imaging showed an extradural cystic mass originating from the ligamentum flavum on the right side in the L5 segment. Microsurgical laminotomy and flavectomy were performed. The symptoms resolved completely and the patient had an uneventful postoperative recovery.

Classification and surgical management of secondary nasal deformity of unilateral cleft lip / 中华整形外科杂志

<p><b>OBJECTIVE</b>To investigate the classification of alar base depression, so as to provide the reference for the surgical management of secondary nasal deformity of unilateral cleft lip.</p><p><b>METHODS</b>From Jul. 2008 to Feb. 2009, 26 cases with secondary deformity of unilateral cleft lip were treated. All the patients underwent 3-dimensional CT for maxillary measurement. The nasal soft tissue measurement was performed pre- and post-operatively. The relationship between the maxillary and soft tissue at alar base was analyzed. The nasal deformity was classified.</p><p><b>RESULTS</b>The location of alar base was not related to the form of piriform aperture, but the bony defect at the alar base was correlated to the patient satisfactory. The nasal deformity was graded as I when the depression at alar base was less than 4.5 mm in depth, as II when it was 4.5-5.0 mm in depth, and as III when it was more than 5 mm in depth. The deformity could be corrected with only soft tissue plasty for grade I, with soft tissue plasty or artificial implants for grade II, with combined bone autograft or alveolar cleft repair for grade III.</p><p><b>CONCLUSIONS</b>The depression at maxillary does not necessarily result in alar base depression. The alar base can be adjust to proper position through operation. The operation should be designed based on the preoperative nasal measurement.</p>

<p><b>OBJECTIVE</b>To study the therapeutic effect of one-staged repair of unilateral cleft lip an nasal deformity with modified Mohler.</p><p><b>METHODS</b>The unilateral cleft lip and nasal deformity were repaired in one stage with modified Mohler. The nasal retainers were kept for at least 6 months. The patients were followed up at 3 months and 12 months after operation.</p><p><b>RESULTS</b>From Sept. 1998 to Aug. 2008, 103 cases, aged from 2.5 m to 12 m, were treated. 3 months after operation, 97 of 103 patients had good appearance of both lips and noses, which included unobvious scars, symmetric Cupid's bows and nostrils, intermedial nasal columellae and eminentia nasal tips. 6 of them had good appearance of noses only with a little malposition of Cupid' s bows. 89 patients were followed up for 12 months with no deterioration of nasal deformity and delayed growth of greater alar cartilages. 3 patients who had malposition of Cupid's bows also got better.</p><p><b>CONCLUSIONS</b>The one-staged repair of unilateral cleft lip and nasal deformity with modified Mohler is very practical.</p>

Genetic diversity and phylogeny in Hystrix (Poaceae, Triticeae) and related genera inferred from Giemsa C-banded karyotypes

The phylogenetic relationships of 15 taxa from Hystrix and the related genera Leymus (NsXm), Elymus (StH), Pseudoroegneria (St), Hordeum (H), Psathyrostachys (Ns), and Thinopyrum (E) were examined by using the Giemsa C-banded karyotype. The Hy. patula C-banding pattern was similar to those of Elymus species, whereas C-banding patterns of the other Hystrix species were similar to those of Leymus species. The results suggest high genetic diversity within Hystrix, and support treating Hy. patula as E. hystrix L., and transferring Hy. coreana, Hy. duthiei ssp. duthiei and Hy. duthiei ssp. longearistata to the genus Leymus. On comparing C-banding patterns of Elymus species with their diploid ancestors (Pseudoroegneria and Hordeum), there are indications that certain chromosomal re-arrangements had previously occurred in the St and H genomes. Furthermore, a comparison of the C-banding patterns of the Hystrix and Leymus species with the potential diploid progenitors (Psathyrostachys and Thinopyrum) suggests that Hy. coreana and some Leymus species are closely related to the Ns genome of Psathyrostachys, whereas Hy. duthiei ssp. duthiei, Hy. duthiei ssp. longearistata and some of the Leymus species have a close relationship with the E genome. The results suggest a multiple origin of the polyploid genera Hystrix and Leymus.

<p><b>OBJECTIVE</b>To investigate the effects and methods of intracranial-extracranial (IC-EC) bypass surgery in the treatment of intracranial aneurysms.</p><p><b>METHODS</b>The clinical material of 9 cases, who performed IC-EC bypass surgery before occlusion of the parental arteries of intracranial aneurysms, was studied retrospectively, especially how to evaluate the co-lateral circulation of the parental arteries and how to select the different methods of IC-EC bypass surgery.</p><p><b>RESULTS</b>The co-lateral circulation in 9 cases was not enough to meet the need of the cerebral blood flow after occlusion of the parental arteries of the aneurysms. Revascularization by different methods of IC-EC bypass surgery and then occlusion of the parental arteries, ischemia in the brain area feeding by occluded parental arteries of the aneurysms did not occurred.</p><p><b>CONCLUSION</b>When the co-lateral circulation of the parental arteries of intracranial aneurysm is not enough, the revascularization by different methods of IC-EC bypass surgery is needed before occlusion of these arteries.</p>

Entire restoration of deformities caused by naso-orbito-ethmoidal complex and adjacent craniomaxillofacial fracture / 中华口腔医学杂志

<p><b>OBJECTIVE</b>To introduce the therapy of malformation caused by naso-orbito-ethmoidal (NOE) complex and adjacent craniomaxillofacial fracture.</p><p><b>METHODS</b>Seventy-six cases with NOE complex and adjacent craniomaxillofacial fracture underwent surgical replacement and internal fixation, using several cosmetically favorable incisions. At the same time, nasal reconstruction was performed to correct nasal deformities and defect through the coronal access during the exposure for the treatment of the NOE fracture. If larger nasal fragments were present, they were reduced and fixed by microplates or wires. If there was lack of septal support, dorsal nasal bone grafting was used to reestablish the height and anterior projection of the nose. Synthetic material (Medpor) was chosen for restoration of the orbital defects. Transnasal reduction was used for canthopexy.</p><p><b>RESULTS</b>After 3 - 6 months follow-up, the outcomes of these patients were satisfactory functionally and esthetically. Posttraumatic nasal malformation and enophthalmos were corrected in most cases, and residual enophthalmos occurred in 3 cases, diplopia in 2 cases, insufficient prominence in 5 cases which underwent secondary correction with good results. Transnasal reduction of canthal realignment in the type III fracture was also satisfactory. There was no complication in this group.</p><p><b>CONCLUSIONS</b>Comprehensive pre-operative evaluation of the patient and careful examinations should be taken to workout an appropriate operation plan. Simultaneous restoration for this type of complicated fracture is critical to obtain good results.</p>
