Therapeutic Efficacy of Acupuncture at Baihui (GV 20) and Shenting (GV 24) for Post-stroke Cognitive Impairment: A Systematic Review / 上海针灸杂志

Objective To evaluate the clinical efficacy of acupuncture at Baihui (GV 20) and Shenting (GV 24) in treating post-stroke cognitive impairment (PSCI) by using the systematic review method.Method Via computer, Chinese Journal Full-text Database (CJFD), Wanfang, China Biology Medicine disc (CBMdisc), Chinese Science and Technology Periodical Database, PubMed, Foreign Evidence-Based Medicine (FEMB), the Cochrane Library were retrieved.Chinese Acupuncture and Moxibustion andShanghai Journal of Acupuncture-moxibustion were manually retrieved. Randomized controlled trials published before Jan 31st of 2013 on acupuncture at Baihui (GV 20) and Shenting (GV 24) in treating PSCI, both in Chinese and English, were collected. The required data were extracted, then were evaluated according to the criteria of Cochrane systematic review and underwent meta-analysis by using RevMan 5.0.Result Twenty-two clinical trials were finally recruited, including 1637 subjects. The meta-analysis showed that acupuncture at acupoints including Baihui (GV 20) and Shenting (GV 24) produced a more significant rehabilitation result compared to single rehabilitation training or medication. The comparison of Mini-Mental State Examination (MMSE) score showed: [WMD=3.37, 95％CI (1.70, 5.05),P<0.00001]; the comparison of P300 latency: [WMD=1.22, 95％CI (0.84, 1.59),P<0.00001]. Severe adverse reactions were not discovered. Conclusion Acupuncture at Baihui (GV 20) and Shenting (GV 24) can effectively improve the cognitive function of PSCI patients. However, the diagnostic criteria and evaluation indexes are expected to be unified and standardized, and the clinical trials on acupuncture intervening PSCI are required to be further improved methodologically.

In vitro tumor cytotoxic activities of extracts from three Liriodendron plants

The extracts prepared from Liriodendron tulipifera Linn., L. chinense [Hemsl.] Sarg., and their hybrid L. chinense x L. tulipifera, were investigated for their cytotoxic abilities in vitro against five human cancer cell lines: MDAMB-231 and MCF-7 breast cancer cells, SGC-7901 gastric cancer cells, HuH-7 hepatocarcinoma cells, and HCT-15 colon carcinoma cells, and then measured their phenols and alkaloids contents. Of these plant extracts, some of them, especially the lower polar extracts from barks, exhibited potent cytotoxic effects on five tested tumor cell lines

Complications of hyoid suspension with Repose system on obstructive sleep apnea hypopnea syndrome / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To investigate the complications of hyoid suspension with Repose system on obstructive sleep apnea hypopnea syndrome (OSAHS) and to find out the effective prevention strategies.</p><p><b>METHODS</b>Forty four patients diagnosed by polysomnography as OSAHS were received hyoid suspension with Repose system from June 2005 to July 2009. The intraoperative and postoperative complications were analyzed retrospectively. The patients who reported abnormal swallowing were evaluated with water drinking test and video fluorography swallow study to assess biomechanical changes in swallowing.</p><p><b>RESULTS</b>Incidence rate of perioperative titanium nial amotio was 15.9% (7/44). It was avoided by implanting titanium nial again. No perioperative complications occurred such as injury of superior laryngeal nerve, blood vessel and thyrohyoid membrane, fracture of hyoid bone, suture break. All patients developed dysfunctions of pronunciation and swallowing, edema of mouth floor, dysfunctions of movement of tongue that could relieved gradually after three days on most patients. No postoperative complications occurred such as titanium nial amotio, fat liquoring, edema of mouth floor, hematoma, infection, foreign body reaction, injury of root apex of anterior tooth, dysfunctions of movement and sensation of tongue, suture break and death. All patients had over 2 year postoperative follow up. Incidence rate of dysfunctions of pronunciation and swallowing was 4.5% (2/44) and 15.9% (7/44) respectively. Main situation for dysfunctions of pronunciation was speaking ambiguity. Major manifestations of swallowing abnormalities were occasional aspiration, food going down the wrong tube, food becoming stuck in the throat, deglutition with bowing head. Seven patients who had abnormal swallowing possessed normal water drinking test and occurred asynersis of hyoid movement and laryngeal elevation, but aspiration were not observed. Three patients presented obvious stagnation in epiglottic vallecula and sinus piriformis.</p><p><b>CONCLUSIONS</b>Most complications of hyoid suspension with Repose system may be avoided or recovered on short term. Postoperative dysfunctions of pronunciation and swallowing may exist for a long time.</p>

Complications of tongue base reduction with radiofrequency tissue ablation on obstructive sleep apnea hypopnea syndrome / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To investigate the complications of tongue base reduction with radiofrequency tissue ablation on patients with obstructive sleep apnea hypopnea syndrome (OSAHS) and find out the effective prevention strategies.</p><p><b>METHODS</b>One hundred and ninety three OSAHS patients diagnosed by polysomnography were received tongue base reduction with radiofrequency tissue ablation between March 2008 and December 2009. The intraoperative and postoperative complications including bleeding, hematoma of tongue base, abscess of tongue base, altered taste, tongue numbness, deviation of tongue extension movement, dysfunctions of pronunciation and swallowing as well as the managements were analyzed retrospectively.</p><p><b>RESULTS</b>No perioperative complications occurred. There were 186 cases with postoperative pain (96.4%), 155 cases with submandibular edema (80.3%). Nocturnal sudden cardiac death was encountered in 1 case and secondary bleeding in 1 case. There was no ulceration of tongue base mucose, hematoma or abscess of tongue base, altered taste, tongue numbness, tongue deviations, speech, swallowing and taste disorder after operation. The scale of postoperative pain claimed by patients was ranged between mild to moderate. Diclofenac suppository had analgesic effect for these patients. The quantity of bleeding in patient with secondary hemorrhage was so little that after proper treatment the bleeding was stopped and never happened again. Patient with nocturnal sudden cardiac death occurred at thirty-seven hours after operation, because of swelling and pain of tongue base aggravated sleep apnea and night hypoxemia inducing fatal arrhythmia.</p><p><b>CONCLUSIONS</b>Postoperative pain and submandibular edema were 2 most common postoperative complications which can be easily controlled by antibiotics, Glucocorticoids and Diclofenac suppository. For those severe OSAHS patients accompanied by cardiopulmonary diseases, the tongue base reduction with radiofrequency tissue ablation can induce nocturnal sudden cardiac death. It is important to pay more attention on arrhythmias at night in severe OSAHS patients.</p>

Comparison of composite grafting of autoskin with acellular dermal matrix from different sources / 中华烧伤杂志

<p><b>OBJECTIVE</b>To compare the composite grafts of acellular dermal matrix (ADM) from different sources with autoskin.</p><p><b>METHODS</b>Six local white mini pigs were employed for the experiment. The pigs were randomly divided into four groups according to different skin grafts, i.e. A (human ADM with razor thin autoskin), B (porcine ADM with razor thin autoskin), C (razor thin autoskin only), and D (split thickness autoskin) as control. The survival rate, the contraction degree of the grafts, and the histological changes in grafting area were observed at 2, 4, 8, 12 and 24 hours after the operation.</p><p><b>RESULTS</b>The grafted area in both A and B groups appeared smooth and elastic with satisfactory graft survival. The in growth of the host reparative cells such as fibroblast and vascular endothelium could be induced by composite grafts of different ADMs with skin grafting. The contraction areas in A and B groups seemed bigger than those in C and D groups. The tissue structure of grafting areas was similar to that of split thickness skin grafting area at 24 post-operation weeks.</p><p><b>CONCLUSION</b>Combination of the homogenous and heterogeneous ADMs with autografts exhibited similar biological function during the observation period (24 weeks after operation). Xenogenous ADMs might have broader clinical applications.</p>
