OBJECTIVETo observe the therapeutic effect of Qingfei Huatan Quyu method (QHQ, a Chinese medicinal therapy for clearing Fei-heat and dissolving phlegm-stasis) combined with hormone-antibiotic therapy (HAT) on radiation pneumonia (RP).

METHODSEighty-one patients with RP were randomized into two groups, 41 patients in the control group and 40 in the treatment group were treated with HAT alone and HAT combined with QHQ respectively for 21 days. The severity of RP was evaluated before and after treatment according to the criteria of the radiation therapy oncology group. The effect on TCM symptoms and chest roentgenogram, as well as on plasma levels of interleukin-6 ( IL-6) and transform growth factor-beta (TGF-beta) were detected.

RESULTSAfter treatment, number of patients with RP graded as 0, 1, 2, 3, and 4 in the treatment group was 23, 10, 4, 2, and 1, respectively, while in the control group, 14, 9, 11, 4, and 3, respectively. The combined therapy showed effects in improving RP grading (P <0.01) and TCM syndromes were superior to those of HAT respectively (P < 0.05). Besides, levels of IL-6 and TGF-beta were lowered after treatment in the treatment group, showing a significant difference to those in the control group (P <0.05).

CONCLUSIONQHQ combined with HAT has a definite therapeutic effect on RP. It could efficiently decrease the plasma levels of IL-6 and TGF-beta in patients with RP.

AIM:To investigate the value of 3D-optical coherence tomography (OCT) in the diagnosis of macular disease before phacoemulsification.METHODS:Clinical records of 423 cataract patients (512 eyes) who underwent phacoemulsification combined with intraocular lens implantation in our hospital from June to December in 2015 were retrospectively analyzed.In addition to preoperative routine examination of fundus, Topcon 3D-OCT 2000 was used to examine the macula, the detection rate of macular disease was compared, risk factors of cataract combined with macular disease were analyzed.RESULTS:The OCT image results of 305 cases (384 eyes, 72.1%) were successfully obtained, 133 cases showed macular disease (146 eyes), the detection rate was 28.5% (95%CI:27.64%-29.40%);the macular disease of 35 cases (37 eyes) were detected by routine examination of fundus before operation, the detection rate was 7.2% (95%CI:6.72%-7.74%);the detection rate of 3D-OCT was significantly higher than routine examination of fundus for macular disease (χ2=79.05, P<0.01).Female, over 65 years old, surgical history of diseased eye, and high myopia were risk factors of cataract combined with macular disease, the relative risk was 1.705 (95%CI:1.091,2.664), 1.893 (95%CI:1.219,2.939), 6.593 (95%CI:2.027,21.447) and 95%CI:5.130 (2.841,9.263) respectively, the risk of cataract combined with macular disease showed an increasing trend with rising age.CONCLUSION:In preoperative examination of cataract patients, 3D-OCT has higher sensitivity in the detection of macular disease, especially for women, over 65 years old, high myopia and surgical history of diseased eye, 3D-OCT can be used as a routine preoperative examination.

Objective To study the relationships between single nuchotide polymorphisms (SNP) of gene rash homebox-1(MSX-1)(rs3821949,rs12532)and sporadic tooth agenesis by filtering the susceptibility genes in a Jiangsu province population.Methods DNA samples were extracted from 198 patients with sporadic tooth agenesis and 207 control subjects.Two MSX-1 gene polymorphisms were genotypod using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay.The association between the genetic polymorphism and risk of sporadic tooth agenesis wag estimated by χ2 and logistic regression.The Phase wag used to determine the Hardy-Weinberg equilibrium and haplotype association.Results In the population,the allele frequency and genotype rates of the SNP rs3821949 were significant different between the patients with sporadic tooth agenesis and normal controls:the A allele frequency in the patients (43.2%) was significantly higher than that in the normal controls (31.4%,P=0.008),and the AA genotype rate ofthe patients (14.7%) was significantly higher than that of the controls (12.6%,P=0.030).However,There were no significant diffeFences in the allele frequency and genotype rates of the SNP rs12532 between the patients with sporadic tooth agenesis and normal control s.Similar results were obtained between the mandibular ineisor agenesis cases and controls.The haplotype frequencies of GA(27.9%)were significantly lower in non.mandibular incisor agenesis cases group than that in the control group(37.0%,P=0.03,OR=0.51).Conclusions The results show that SNP rs3821949,which is located at 5'near region of the MSX-1 gene,is likely to have an influence on the transcriptional activity of this gene and be associated with sporadic tooth agenesis.The haplotypes constructed with these 2 SNP sites may be linked with the susceptibility gene of non-mandibular incisor agenesis.

Objective To summarize regularities in acupoint prescriptions for acupuncture treatment of stroke disorders by using data mining techniques to analyze 150 ancient acupuncture books from the Han dynasty to the end of Qing dynasty. Method A standard database and a ancient book database were established by a manual entry and proofreading method. The sentences containing stroke disorders, acupoints, meridians and needling moxibustion method in the ancient books were selected according to the key words in the standard database using a variety of data mining techniques and a regular relation to establish corresponding disease, acupoint, needling moxibustion method and meridian databases. They were classified into two types: prescriptions for stroke disorders and acupoint indications containing stroke disorders. The results from selection were reviewed manually and standardized. A multilevel analysis of regularities in acupuncture prescriptions for stroke disorders in the ancient books was performed by statistical analysis and apriori algorithm on association rules with support degree and confidence level. Result There were a total of 536 records on acupuncture point prescription for stroke disorders. Single acupoint prescriptions accounted for 34.89% of the total number of prescriptions. The single acupoint that was used most frequently was Baihui(GV20). Thedouble acupoints that were combined most frequently were Quchi(LI11) and Baihui. In three acupoint combination, Quchi and Fengshi(GB31) were separately combined most frequently with Baihui, Jianyu(LI15) and Xuanzhong(GB39). The three meridians that were used most frequently were the Du Meridian, the Large Intestine Meridian of Hand-Yangming and the Gallbladder Meridian of Foot-Shaoyang. The two meridians that were combined most frequently were the Gallbladder Meridian of Foot-Shaoyang and the Stomach Meridian of Foot-Yangming. Crossing points and Five-Shu points were selected most frequently in specific points. He-Sea points were used most frequently in Five-Shu points. Conclusion The prescriptions for stroke disorders in ancient acupuncture books focus on selecting the confluence of all yang meridians and yang meridian points. Specific points are the important composition of the prescriptions. Crossing points and He-Sea points are mainly used in specific points.

Design space approach is applied in this study to enhance the robustness of first ethanol precipitation process of Codonopsis Radix (Dangshen) by optimizing parameters. Total flavonoid recovery, dry matter removal, and pigment removal were defined as the process critical quality attributes (CQAs). Plackett-Burman designed experiments were carried out to find the critical process parameters (CPPs). Dry matter content of concentrated extract (DMCE), mass ratio of ethanol to concentrated extract (E/C ratio) and concentration of ethanol (CEA) were identified as the CPPs. Box-Behnken designed experiments were performed to establish the quantitative models between CPPs and CQAs. Probability based design space was obtained and verified using Monte-Carlo simulation method. According to the verification results, the robustness of first ethanol precipitation process of Dangshen can be guaranteed by operating within the design space parameters. Recommended normal operation space are as follows: dry matter content of concentrated extract of 45.0% - 48.0%, E/C ratio of 2.48-2.80 g x g(-1), and the concentration of ethanol of 92.0% - 92.7%.

ITS2 sequence was used as a barcode to identify herbal tea ingredient Plumeria rubra and its adulterants. Genomic DNAs from forty eight samples were extracted, the ITS2 sequences were amplified and sequenced bi-direstionlly, and then assembled and obtained using CodonCode Aligner. The sequences were aligned using ClustalW, the genetic distances were computed by kimura 2-parameter (K2P) model and the Neighbor-joining (NJ) phylogenetic trees were constructed using MEGA5.0. Results showed that the length of ITS2 sequence of P. rubra were 244 bp. The intra-specific genetic distances (0-0. 016 6) were much smaller than inter-specific ones between P. rubra and its adulterants(0.320 8-0.650 4). The NJ tree indicated that P. rubra and its adulterants could be distinguished clearly. Therefore, Using ITS2 barcode can accurately andeffectively distinguish herbal tea ingredient P. rubra from its adulterants, which providesa new molecular method to identify P. rubra and ensure its safety in use.

OBJECTIVETo investigate the effect of chitosan on the capsule inside the expanded flap.

METHODSThe expanders were implanted in animals with the treatment of chitosan(experimental group, n = 15) or without (control group, n = 15). After taking out the expanders, the flap contraction rate was calculated. The samples were observed through HE, Masson dyeing and CD34 immunohistochemical study. The thickness of capsule inside the expanded flap was measured under microscope. The samples were also studied under electron microscope.

RESULTSThe thickness of capsule was 516.000 +/- 128.491 microm in the experimental group, and 833.000 +/- 227.379 microm in the control group (P < 0.05). The number of microvessels was 8.200 +/- 2.150 per visual in experimental group, and 7.900 +/- 1.729 per visual in control group (P > 0.05). Under the electron microscope, the rough endoplasmic reticulum (RER) in the capsule in experimental group decreased and enlarged with degranulation. The mitochondria emerged or disappeared. The number of ribosome was reduced. In the control group, the RER enlarged without degranulation, the mitochondria was intact. The number of ribosome was not reduced.

CONCLUSIONSThe chitosan can effectively reduce the contraction of expanded flap through collagen secretion of fibroblast, delaying the differentiation from fibroblast to fiber cell, inhibiting thansform from fibroblast to myofibroblast. It has no effect on the microvascular generation and expansion, so the flap blood supply will not be affected with thicker capsule.

OBJECTIVETo explore the value of video-thoracoscopy in the thoracoscopic mobilization of the thoracic esophagus combined with radical lymphadenectomy.

METHODSBetween March 2002 and May 2003, thoracoscopic mobilization of the thoracic esophagus combined with radical lymphadenectomy was attempted in 25 patients (test group) and 22 cases received routine open thoracotomy (control group). Mean age was 55 years (range 34 - 73). The cancers were T(1)-T(3). Dissection of the thoracic esophagus was attempted via a right-sided approach, followed by a laparotomy and a cervical incision.

RESULTSThe thoracoscopic procedure was successful in all patients. There was no post-operative death in two groups. Mean node harvest was (7.8 +/- 1.7) nodes for test group and (7.5 +/- 1.3) nodes for control group (P > 0.05). Mean blood lo of the thoracic component was (130 +/- 83) ml for test group and (350 +/- 135) ml for control group (t = 6.83, P < 0.05). Median post-operative stay was (10.9 +/- 2.5) days for test group and (14.6 +/- 1.7) days for control group (t = 5.87, P < 0.05).

CONCLUSIONVideo-thoracoscopy could potentially provide an oncologically sound means for resecting the thoracic esophagus without the need for a thoracotomy. Radical thoracoscopic mobilization of the esophagus is feasible.
