Objective To summarize the treatment principle of acupuncture-moxibustion in treating Bi-impediment syndrome from the application rules of meridians and acupoints in Ming-Qing Dynasties by sorting out and analyzing the Chinese medicine literatures about acupuncture-moxibustion for Bi-impediment syndrome in Ming-Qing Dynasties, for providing literature evidence for basic and clinical research of Bi-impediment syndrome.Method Via electronic retrieval ofZhong Hua Yi Dian (Zhen Jiu Tui Na Lei) (Chinese Medical Encyclopedia,Chapter of Acupuncture-Moxibustion and Tuina), the data related to Bi-impediment syndrome in Ming-Qing Dynasties were extracted to establish a database categorized by meridians and acupoint features in Excel for analysis.Result There were 267 items of records about acupuncture-moxibustion in treating Bi-impediment syndrome in Ming-Qing Dynasties, involving the fourteen ordinary meridians, and 131 acupoints including 5 extra points; the frequency of using the Gallbladder Meridian ranked the top, followed by the Large Intestine Meridian; points from the Bladder Meridian were predominant, followed by the Gallbladder Meridian; there were 28 commonly-used acupoints (frequency>5), which were Quchi (LI 11, 26 times), Huantiao (GB 30, 23 times), Hegu (LI 4, 22 times), Chize (LU 5, 16 times),Yanglingquan (GB 34, 15 times), and Weizhong (BL 40, 14 times). Of the specific acupoint, the five Shu points were most frequently used, with a frequency of 217.Conclusion In the treatment of Bi-impediment syndrome with acupuncture-moxibustion, doctors in Ming and Qing Dynasties selected yang meridians more often than yin meridians, and Gallbladder, Large Intestine and Bladder Meridians had comparatively higher frequencies; regarding the application of acupoints, the specific acupoints were often used, especially the five Shu acupoints. The study results provide reference for acupoint selection in the treatment of Bi-impediment syndrome with acupuncture-moxibustion.

OBJECTIVETo research the efficacy,security and necessity of combined therapy for preventing postsurgery stiffness after elbow fracture.

METHODSFrom May 2009 to April 2010, 60 patients with elbow fractures treated by operation were randomly divided into two groups: combined therapy group and past procedure group. Thirty patients in the combined therapy group,including 12 males and 18 females, ranging in age from 23 to 63 years, averaged (43.53 +/- 7.74) years old; 15 patients had two parts fractures, including humeral intercondylar fractures combined with olecroanon and (or) ulna coronoid process fractures in 8 cases, fractures of exterior and interior humeral condyle combined with capitulum radius in 3 cases, fractures of olecroanon and ulna coronoid process in 3 cases, fractures of olecroanon and capitulum radius in 1 case; other 15 patients had one part fractures, including fractures of exterior or interior humeral condyle in 8 cases,fractures of olecroanon or ulna coronoid process in 6 cases, fractures of capitulum radius in 1 patient. Thirty patients in the past procedure group,including 11 males and 19 females, ranging in age from 24 to 67 years, averaged (46.13 +/- 6.22) years; 15 patients had two parts fractures, including fractures of humeral intercondylar fracture combined with olecroanon and(or) ulna coronoid process in 7 cases, fractures of exterior and interior humeral condyle combined with capitulum radius in 2 cases,fractures of olecroanon and ulna coronoid process in 5 cases,fractures of humeral intercondylar fracture combined with capitulum radius in 1 patient; 15 pa- tients had one part fracture, including fractures of exterior or interior humeral condyle in 6 cases, fractures of olecroanon or ulna coronoid process in 8 cases, fractures of capitulum radius in 1 patient; the patients in the past procedure group were treated with past procedure methods. Mayo Elbow Performance Score (including gmotion of elbow joint) and security (using X-ray to recheck displacement fracture, internal fixation failure and heterotopic ossification) were evaluated at postoperative 6 months. From 2002 to 2006, 30 patients were reviewed as historical control group, including 17 males and 13 females, ranging in age from 27 to 62 years, averaged (47.17 +/- 7.83) years; 15 patients had two parts fractures, including fractures of humeral intercondylar combined with olecroanon and(or) ulna coronoid process in 7 cases, fractures of exterior and interior humeral condyle combined with capitulum radius in 1 case, fractures of olecroanon and ulna coronoid process in 6 cases, fractures of ulna coronoid process and capitulum radius in 1 case; 15 patients had one part fractures,including fractures of exterior or interior humeral condyle in 9 cases, fractures of olecroanon or ulna coronoid process in 5 cases,fractures of capitulum radius in 1 case. The Mayo Elbow Performance Score of the patients in historical control group was evaluated retrospectively at postoperative 6 months and the results were compared with that of past procedure group.

RESULTSMayo score of combined therapy group was (91.00 +/- 7.81)surpassed to (76.83 +/- 10.71) of the past procedure group and (73.17 +/- 1.99) of historical control group (F = 24.98, P < 0.05). The range of motion of elbow was (102.40 +/- 9.16) degrees of combined therapy group surpassed to (83.57 +/- 6.21) degrees of the past procedure group (t = 9.325, P < 0.05). There were no internal fixation loose,obvious fracture displacement and heterotopic ossification in each X-ray examination of patients in the combined therapy group. The Mayo score of historical control group was (73.17 +/- 11.99), showing no significant differences when compared with (76.83 +/- 10.71) of the past procedure group (LSD, P = 0.172).

CONCLUSIONCombined therapy including different stage, different method combination and different subject to practice to prevent postsurgery stiffness after elbow fracture is effect, security and necessity.

OBJECTIVE: To investigate the risk factors for brain injury in preterm infants by a multicenter epidemiological investigation of brain injury in hospitalized preterm infants in Anhui, China. METHODS: Preterm infants who were hospitalized in the department of neonatology in 9 hospitals of Anhui Neonatal Collaboration Network between January 2016 and January 2017 were enrolled as subjects. The data of maternal pregnancy and clinical data of preterm infants were collected, and the logistic regression model was used to analyze the risk factors for brain injury in preterm infants. RESULTS: A total of 3 378 preterm infants were enrolled. Of the 3 378 preterm infants, 798 (23.56%) had periventricular-intraventricular hemorrhage (PVH-IVH), and 88 (2.60%) had periventricular leukomalacia (PVL). Intrauterine distress, anemia, hypoglycemia and necrotizing enterocolitis (NEC) were risk factors for PVH-IVH (OR=1.310, 1.591, 1.835, and 3.310 respectively; P<0.05), while a higher gestational age was a protective factor against PVH-IVH (OR=0.671, P<0.05). PVH-IVH, NEC and mechanical ventilation were risk factors for PVL (OR=4.017, 3.018, and 2.166 respectively; P<0.05), and female sex and use of pulmonary surfactant were protective factors against PVL (OR=0.514 and 0.418 respectively; P<0.05). CONCLUSIONS Asphyxia/anoxia, infection/inflammation, mechanical ventilation, anemia and hypoglycemia may increase the risk of brain injury in preterm infants.

OBJECTIVETo compare efficacy differences between fire filiform needle combined with mild moxibustion and gabapentin combined with sham acupuncture for postherpetic neuralgia (PHN).

METHODSOne hundred cases of PHN were randomly divided into a needle group and a medicine group, 50 cases in each one. In the needle group, pricking method of fire filiform needle was given at the Ashi points, and then mild moxibustion was applied for 15 min. In the medicine group, the oral administration of gabapentin capsule and sham acupuncture at non-acupoints in the distal end of lesions were applied. The treatment was required for 21 days in both groups. The visual analogue score (VAS) was recorded before treatment and on the 1st day, 2nd day, 3rd day, 6th day, 9th day and 12th day of treatment. The most severity of pain within last 24 h, preset severity of pain, immediate analgesia effect and starting time of pain relief were observed, also the efficacy was assessed and improvement of symptoms was observed in the follow-up visit.

RESULTSThe total effective rate was 94.0% (47/50) in the fire filiform needle group, which was superior to 86.0% (43/50) in the medicine group (P < 0.05). Compared with medicine group, the VAS of the most severity of pain within last 24 h was obviously reduced after the 2nd treatment in the fire filiform needle group while that of present severity of pain was relieved after the 1st treatment (both P < 0.05). The immediate analgesia effect in the fire filiform needle group was obviously superior to that in the medicine group in the first three times of treatment (all P < 0.05). The average time of pain relief was (3.91 +/- 0.82) days in the fire filiform needle group, which was significantly earlier to (6.53 +/- 1.13) days in the medicine group (P < 0.05). 26 cases were cured in the fire filiform needle group in the follow-up visit, which was superior to 2 cases in the medicine group (P < 0.05). The improvement of VAS, pain range and sleep quality in the needle group were also superior to those in the medicine group (all P < 0.05). The direct medical cost in the fire filiform needle group was (232.32 +/- 48.108) yuan, which was significantly lower than (466.00 +/- 41.09) yuan in the medicine group (P < 0.05). There was only one case of adverse effect in the medicine group during the treatment.

CONCLUSIONThe fire filiform needle combined with mild moxibustion could obviously relieve the pain in PHN patients, which has superior immediate analgesia effect and pain relieving time compared with gabapentin, which also has less adverse effects and cheap cost.

Objective To explore the establishment of the mimetic aging effect in guinea pigs induced by D-galactose, and to detect the biological indicatrix associated with hearing loss and provide a new tool for molecular pathogenesis of hearing loss.Methods Total of 51 guinea pigs were randomly divided into three groups: group A ( model aging group , n = 25) , which were injected with D-galactose (200 mg ·kg-1·d-1 ) by intra peritoneum for 6 weeks, group B ( model control group , n = 18), which were given the same amount of saline only, and group C(vacant group, n = 15) were not treated.Then, The guinea pigs in group A and B were exposed in noise for 8 days, 8 hours once a day.Auditory brainstem response (ABR) was used to test the hearing threshold of guinea pigs thrice, first before the drug administered, then after 6 weeks the drug used, third after noise exposure.And colorimetry was used to analyze the activity of superoxide dismutase (SOD) and malon dialdehyde (MDA) in brain and liver tissue.The DNA of inner ear tissue was harvested and amplified fragment length polymorphism (AFLP) was used to detect the differential polymorphic markers.Results After injection, there was no significant difference in elevation of ABR threshold between the group A and group B ( t = 1.14, P>0.05 ).However, exposure of noise later, elevation in ABR threshold of ( 22.97±10.56) dB PeSPL was observed in group A, and ( 14.16±7.36) dB peSPL in group B.The was significant difference in variation of hearing threshold between group A and group B ( t = 2.78 ,P<0.05 ).The activity of SOD in brain and liver tissue in group A was lower than that in group B.the level of MDA was opposite between group A and group B.The difference between group A and group B was significant ( P<0.01 ) .A differential polymorphic marker was observed by AFLP. Conclusions The mimetic aging effect of the guinea pigs can be induced by D-galactose, and this model can not directly induce the hearing loss.The differential polymorphic marker possibly act as a predisposing factor which can greatly enhance the sensitivity of the ear to the noise.

OBJECTIVEAn accurate clinical TNM staging of lung cancer is essential for the precise determination of the extent of the disease in order that an optimal therapeutic strategy can be planned. This is especially true in patients with marginally resectable tumors. Clinical over-staging of the disease may deny a patient the benefit of surgery, whereas under-staging may oblige a patient to accept a fruitless or even harmful surgery. We aimed to analyze preoperative clinical (c-TNM) and postoperative surgico-pathologic staging (p-TNM) of lung cancer patients in order to evaluate the accuracy of our clinical staging and its implications on the surgical strategy for lung cancer.

METHODSWe did a retrospective comparison of c-TNM and p-TNM staging of 2007 patients with lung cancer surgically treated from January 1999 to May 2003. Preoperative evaluation and c-TNM staging of all patients were based on physical examination, laboratory studies, routine chest X-ray and CT scan of the chest and upper abdomen. Other examinations included sputum cytology, bronchoscopy, abdominal ultrasonography, bone scintiscan, brain CT/MRI, and mediastinoscopy whenever indicated.

RESULTSIn the present study the comparison of c-TNM and p-TNM staging of 2007 patients with lung cancer revealed an overall concurrence rate of only 39.0%. In the entire series the extent of disease was clinically underestimated in 45.2% and overestimated in 15.8% of the patients. Among all c-TNM stages the c-IA/B stage of 1105 patients gave the highest rate (55.2%) of underestimating the extent of disease. Clinical staging of T subsets was relatively easy with an overall accuracy rate of 72.9%, while that of N subsets was relatively more difficult with an overall accuracy rate of 53.5%. Analysis also showed that c-IV stage may not be an absolute contraindication to surgery, because in half of the patients, c-M1 turned out to be p-M0, providing the possibility of resectional surgery depending on the status of T and N.

CONCLUSIONFor reasons to be further determined, the present preoperative clinical TNM staging of lung cancer remains a crude evaluation. Further efforts to improve its accuracy are needed.

INTRODUCTIONIt is important to decrease the radiation exposure of normal tissue in intensity-modulated radiation therapy (IMRT). Minimizing planning target volume (PTV) margins with more precise target localization techniques can achieve this goal. This study aimed to quantify the extent to which organs at risk (OARs) are spared when using reduced margins in the treatment of nasopharyngeal carcinoma (NPC).

METHODSTwo IMRT plans were regenerated for 40 patients with NPC based on two PTV margins, which were reduced or unchanged following cone beam computed tomography online correction. The reduced-margin plan was optimized based on maximal dose reduction to OARs without compromising target coverage. Dosimetric comparisons were evaluated in terms of target coverage and OAR sparing.

RESULTSImprovements in target coverage occurred with margin reduction, and significant improvements in dosimetric parameters were observed for all OARs (P < 0.05) except for the right optic nerve, chiasm, and lens. Doses to OARs decreased at a rate of 1.5% to 7.7%. Sparing of the left parotid and right parotid, where the mean dose (Dmean) decreased at a rate of 7.1% and 7.7%, respectively, was greater than the sparing of other OARs.

CONCLUSIONSSignificant improvements in OAR sparing were observed with margin reduction, in addition to improvement in target coverage. The parotids benefited most from the online imaging-guided approach.
