Instructional system design is an important component of instruction. Chaos theory is used in instructional system design of clinical teaching. Application of butterfly effect, fractals and strange attractors theory enhances students’clinical capabilities and comprehensive ability to analyze and solve problems.

OBJECTIVETo evaluate the efficacy and safety of acupuncture-moxibustion combined with modified Mojie tablet (see text) in the prevention of the recurrence of endometriosis (EMS) after laparoscopic surgery.

METHODSAfter laparoscopic surgery, 120 cases of EMS were randomized into an acupuncture-moxibustion group, a western medication group, a Chinese medication group and a combined therapy of acupuncture-moxibustion and Chinese medication group (combined therapy group), 30 cases in each one. In the acupuncture-moxibustion group, acupuncture was applied at Xuehai (SP 10), Sanyinjiao (SP 6) and Guanyuan (CV 4); the isolated moxibustion with ginger was used at Guanyuan (CV 4), once a day, twice a week. In the western medication group, gestrinone was prescribed for oral administration, 2.5 mg, once a day, twice a week. In the Chinese medication group, the self-prepared Mojie tablet were prescribed for oral administration. In the combined therapy group, acupuncture, moxibustion and modified Mojie tablet for oral administration were used in combination. The therapeutic methods were same as the acupuncture-moxibustion group and the Chinese medication group. Totally, the treatment of 3 months was required. Separately, before treatment, after treatment, in 3 months after treatment and in 6 months after treatment, EHP-5 score (endometriosis health profile-5), the abdominal/vaginal ultrasound examination, serum CA125 detection and safety index (ALT detection) were compared in patients among 4 groups.

RESULTSIn 3 and 6 months after treatment, the positive rates of EHP-5 score were 0% (0/30) in the combined therapy group and 0% (0/30) in the acupuncture-moxibuston group, which were all lower significantly than 13.3% (4/30) in the western medication group (both P < 0.05). In follow-up stage of 6 months after treatment, there was no recurrence case in abdominal lviginal ultrasound examination in the combined therapy group, which was lower than 13.3% (4/30) in the western medication group (P < 0.05); the serum CA125 detection in the combined therapy group did not find any abnormal case, which was lower than 16.7% (5/30) in the western medication group (P < 0.05). At the end of treatment session and in the follow-up stage of 3 months after treatment, the abnormal rate of ALT were 20.0% (6/30) and 13.3% (4/30) in the western medication group, which were higher than those in any of the rest groups (P < 0.05). In the follow-up stage of 6 months after treatment, there were 3 abnormal cases of ALT in the western medication group, but which was not different significantly as compared with the rest groups (P > 0.05).

CONCLUSIONAcupuncture and moxibustion combined with modified Mojie tablet effectively prevent from the recurrence of EMS after laparoscopic surgery and improve the life quality of the patients. This combined therapy brings less damage on the liver as compared with the western medication of gestrinone and indicates its definite efficacy and safety.

Objective To study the transcription and expression of excision repair cross complementing 1(ERCC1) in the peripheral blood and the skin tissue in coal-burning borne endemic arsenism, and to explore the role of arsenism in its pathogenic or carcinogenesis mechanism. Methods According to "Endemic arsenism diagnostic criteria" (WS/T 211-2001), 110 arsenism patients were chosen as case group in Xingren county,Guizhou province and they were divided into 3 groups according to their hnir arsenic: ＜ 2(31 cases),2 ～＜ 4(31 cases),≥4 mg/kg(48 cases), respectively. Another 36 healthy residents about 13 km away from the endemic area were chosen as healthy control group. Under the principle of informed consent, hair samples were collected for arsenic analysis by Ag-DDC and blood samples were collected to determine mRNA expression levels of ERCCI by real-time fluorescence quantitative PCR. At the same time, skin tissue samples were collected from the voluntary surgical treatment of 62 patients with endemic arsenism as case group which were divided into 3 groups according to their hair arsenic: ＜ 2(16 cases), 2 ～＜ 4(20 cases) and ≥4 mg/kg(26 cases), respectively, and these patients were also divided into general pathological changes (32 cases), precancerous (19 cases) and cancerous groups( 11cases), respectively, according to their skin pathologic diagnosis of skin lesions. Another 13 cases pathologically normal without skin cancer surgery from a certain hospital were chosen as control group. Skin samples were collected to detect the ERCC1 protein by immunohistochemical method. Results The mRNA levels of ERCC1 were 0.7156(0.2158 ～ 1.2405),0.5772(0.0843 ～ 1.1234) and 0.5490(0.1895 ～ 0.8431 ), respectively, among ＜ 2, 2 ～＜ 4and ≥4 mg/kg groups, which were lower than the mRNA levels of ERCC1 in the control group[1.5128(1.0000 ～2.1295)], and the difference was statistically significant(all P ＜ 0.05). The expression rate of ERCC1 protein were 87.5%, 80.0% and 77.0%, respectively, among ＜ 2, 2 ～＜ 4 and ≥4 mg/kg groups. The expression rate of ERCC1 protein in 2 ～＜ 4 and ≥4 mg/kg groups were lower than the rate in the control group(100.0%), and the difference was statistically significant (all P ＜ 0.05). The expression rate of ERCC1 protein were 84.4%, 79.0%and 72.8%, respectively, among general pathological changes, precancerous and cancerous groups compared with the control group( 100.0% ), and the difference was statistically significant(all P ＜ 0.05). Conclusions Arsenic from coal-burning can lead to abnormal ERCC1 gene transcription and protein expression, which may inhibit DNA repair through influencing the removal of damaged DNA and promoting the incidence of arsenism development and even skin carcinogenesis.

?AIM: To discuss the effect of laser exposure on visual acuity and macula.?METHODS: Retrospective and consecutive case series. A retrospective analysis of 11 patients (11 eyes) with laser retinal injury was carried out from January 2014 to June 2015 in Ophthalmology Department of No. 474 Hospital of Chinese PLA. All individuals underwent visual acuity, best corrected visual acuity ( BCVA ) , and spectral-domain optical coherence tomography ( SD-OCT) for macular at first visit, and fundus fluorescein angiography ( FFA ) , visual field, and multifocal electroretinogram ( mf ERG ) were perform if necessary. Symptomatic therapies, supportive therapies and pars plana vitrectomy ( PPV ) were performed depended on the patient’s condition. The patients were followed-up at 1, 3 and 6mo after the first visit, and patients were undertaken visual acuity, BCVA, macular SD-OCT and so on.?RESULTS: Eight patients ( 73%) were under 18 years old and all patients were young males, who were injured by laser pointers when playing. Three patients ( 27%) over 18 years old were injured accidentally at work. Ten (91%) patients’ BCVA were ≤0. 3, while one ( 9%) patient’s BCVA was higher ≥0. 3. Full-thickness macular holes ( the diameter 224-519 μm ) were detected in 10 patients (91%), while sub-foveal RPE changes and IS/OS injury in 1 patient ( 9%) . Macular hole with traction or cystoid edema in 6 eyes (55%) were received PPV, while the other 5 eyes ( 4 eyes with stable macular hole and 1 eyes with RPE injury ) received conservative treatment. Macular hole closed successfully in 1 eye ( 17%) after PPV, while macular hole in the other 5 eyes ( 83%) were stable after PPV of which the cystoid edema faded. The 4 patients with macular hole and 1 patient with RPE injury were stable during follow-up period. However, the BCVA in all patients had no significant improvement at end.?CONCLUSION: Exposure to laser devices could lead to severe macula injury that could reduce central vision, which is permanent.

Astragalus polysaccharides was lounded to 4-(2-aminoethylphenol), followed by labeling the APS-Tyr with fluorescein-5-isothiocyanate (FITC) at the secondary amino group. The absorption enhancement effects of low molecular weight chitosan and protamine on astragalus polysaccharides were evaluated via Caco-2 cell culture model. The results show that the fluorecent labeling compound has good stability and high sensitivity. On the other hand low molecular weight chitosan and protamine also can promoted absorption of the astragalus polysaccharides without any cytotoxity, and the absorption increase was more significant with increasing the amount of low molecular weight chitosan and protamine. At the same time, the low molecular weight chitosan has slightly better effect. The transepithelial electric resistance (TEER) of Caco-2 cells show that absorption enhancers could improve its membrane transport permeability by opening tight junctions between cells and increasing the cell membrane fluidity.
