There were a lot of general researches and applications about constitution in Shanghan-Zongbing Lun ofPang Anshi. It is found that the constitution idea ofPang Anshi originated from Huangdi-Neijing. His constitution idea included that: the constitution formation was related to living environment and diet; the constitution factors should be considered in the clinical practice; the constitution factors should be considered when applicating Yang-preserving in spring and summer, Yin-preserving in autumn and winter; the constitution factors should be considered in the process of the choice of dosage, the method of decoction and the principle of medication. Pang Anshi constitution idea is of great important guidance for the later medical practice.

BACKGROUND:It is believed that the splintage can promote periodontal tissue repair and improve the prognosis of loose teeth. However, the force of the splint is associated with the rigidity of the splint and adaptation between the teeth and the splint.
OBJECTIVE: To evaluate the therapeutic effects of the nylon composite resin periodontal splint, the
fiber-reinforced composite periodontal splint and the bracket periodontal splint on the treatment of severe periodontitis of the mandibular anterior teeth.
METHODS:Seventy-two patients with severe periodontitis of the mandibular anterior teeth were randomized into 3 groups, with 24 cases in each group: nylon composite resin periodontal splint, fiber-reinforced composite
periodontal splint and bracket periodontal splint groups. The clinical effects of the three kinds of periodontal splints and periodontal indexes were compared at 1, 6 and 12 months after splinting.
RESULTS AND CONCLUSION: The clinical effects in the group of the fiber-reinforced composite periodontal
splint were significantly better than those in the other two groups at 1, 6, 12 months, which were 100%, 100% and 95.8%, respectively. The plaque index, bleeding index, and pocket depth were worse in the group of the nylon
composite resin periodontal splint than the other two groups (P < 0.05). Results suggest that the fiber-reinforced composite periodontal splint is preferred to preserve the loosened teeth with severe periodontitis.

Objective To investigate the clinical characteristics of retinal degeneration (RD) with retinal holes and the therapeutic effect of argon laser therapy. Methods The data of argon laser therapy in 210 RD patients (224 eyes) with retinal holes who underwent the treatment in our department were retrospectively analyzed, which was compared with the data of argon laser therapy in 173 RD patients (198 eyes) without retinal holes. Results In RD patients with retinal holes, 89.7% of the patients were less than 60 years old (53.3% males and 46.7% females). Grid-like degeneration was found in 65.6% of the patients in whom 87.5% had the range of degeneration less than 1 quardrant. There were oval-shaped holes in 60.7% of the patients and accompanied with limited rhegmatogenous retinal detachment (LRRD) in 23.7%. Compared with RD patients without retinal holes, the ratio of patients with the age of≥35 years, cystic degeneration, retinal lengthways small plica, and subjective symptoms was higher in RD patients with retinal holes; while the therapeutic effect of argon laser therapy on patients with LRRD was obviously less than whom without retinal holes (P

OBJECTIVE: To determine the prevalence of GJB2 mutations in newborns and provide clinical experience for newborn genetic screening. METHOD: Blood samples of 23 836 newborns in Beijing from March 2012 to December 2013 were screened for hot spot mutations of GJB2 associated with hearing loss. The genetic screening results were comprehensively analyzed with hearing results in genetic counseling. RESULT: One or two pathogenic mutations of GJB2 were spotted in 622(2. 61%) individuals. Among them, numbers of newborns with 1 mutation of c. 35deiG,c. 176191 del16,c. 235delC and c. 299300 delAT were 3,26,467 and 120. One compound heterozygote, and 5 homozygotes were also identified. Five hundred and fifty(88. 6%)newborns were followed up by telephones and SMS (short message service) and 325 newborns visit our genetic clinic regularly which were regarded as the research object. In the hearing screening, the referral rate for hearing loss in the first-step screening was 13.8% (45/325), and became 9.2% (30/325) upon retesting. Nine newborns (2. 8%) were diagnosed as hearing loss of different degrees as early as 3 months old,including 6 homozygous/compound heterozygote and 3 heterozygotes. CONCLUSION Patients with GJB2 mutations have various phenotype. Newborns with homozygous/compound heterozygous GJB2 mutations may pass the hearing screening at first. Carriers of GJB2 may also have hearing problems. The combination of genetic and audiological screening can play an important role in deafness detections of infants before key period of speech development.

Objective: To study the amount of fat, cholesterol and fatty acid intake in China and provide the basic material for dietary guidance. Methods: Two areas were selected both in North and South China and each area included 3 provinces, or municipality or autonomous region. Three representative survey sites were selected in each province, or municipality or autonomous region. Dietary survey was conducted by the method of weighing and recording and cooking method was also recorded. The amount of food consumption was calculated as standard person (adult male, light physical activity). All foods were gathered as 12 kinds of foods, and each kind of food was cooked and then mixed. The content of fat and fatty acid was analyzed for 8 kinds of foods and the content of cholesterol was analyzed for 4 kinds of foods. The intake of fat, fatty acid and cholesterol per capita was calculated. Results: The amount of fat intake among North I, North II, South I, South II was 70.5 g, 46.5 g, 58.7 g, 71.0 g respectively and the amount of cholesterol intake was 329.6 mg, 128.5 mg, 400.9 mg, 306.0 mg respectively. The main source of dietary fat was from meat and vegetables. Egg was the main source of dietary cholesterol and meat and egg were both the main source of dietary cholesterol in south II area. About 90% of saturated fatty acid was palmitic acid and stearic acid and 90% of monounsaturated fatty acid was oleic acid. Linoleic acid was the principal n-6 polyunsaturated fatty acid and linolenic acid was the principal n-3 polyunsaturated fatty acid. The ratio of S∶M∶P in North I was 1∶1.1∶1, in North II was 1∶1.6∶1.3, in South I was 1∶1.6∶1.3 and in South II was 1∶1.5∶1. Conclusion: The amount of fat intake and fatty acid profile was quite different among different areas and the dietary guidance should be more pertinent The current cholesterol intake was more than dietary guidance in most areas. In addition to egg, meat was also an important source of cholesterol.

Objective To investigate the approach and effect of PDT and TTT therapeutic alliance for isolated choroidal angioma according to the lication. Methods After mydriasis,through 90D retinal mirror examination ,fluorescein fundus angiography (FFA) ,Indocyanine green angiography (ICGA) and ultrasound,the diagnosis of angiography choroidsal hemangioma was made. Position:peripapillary , six cases( tumors locating only in macula fovea were not included in this statistical area). OCT suggested that epithetlial tumors from the surface of nerve macular were affected. Period of the disease was between one week and two months . Preoperative best corrected vision acuity range was 1. 05 ～ 0.4. By ultrasonography, tumors thickenss was from 2.2mm to 4mm, and diameter was from 6.6mm to 11.2mm. OCT indicated that the height of neural epithetlium breaking away from macular area was between 156mm and 486mm. inferior retinas separated two months after morbidity. TTT was partly applied to cure tumor body ortside macdular area with IRIS Medical OculightSLX gallium arsenicde laser(810nm). Energy:per light spot shining diameter was 1 mm, and the power was between 150mw to 250mW, and time was 60s. Therapeutic standard was retinal surface changing to pale. Choroids shrunk back and retinal ptgment epithetlium prolixferated in TTT therapy area;recheck 2 weeks later. If FFA showed that active macula fovea pathological changes were not cured, PDT was performed as following :689nm laser was used , and veteporfin ( comm. ercial name : Visudyne) was injected by intravenous at a speed of 6mg/mm~2 , and 15 minutes later, the laser was irradiated for a period of 83 ～ 126s. For tumors with thicdness under 3mm,one light spot was irradiated for 83s;for rumors with thicdness above 3mm, acouple light apot was irradiated for 125s. A small quantity of hyperpigmintation occurred in the limbus,luteus retinae at the second week of follow up. All the cases were followed up for 3 months to 12 months. Results The final vision reached 0.1 ～ 1.0. OCT showed that the earliest complete recovery of limbus luteus retinae neural epithetlium was at the third week, and for another 3 cases,the recovery was at the 4th week. One case with detachment of retina partial recovered 3 months after treatment. OCT suggested that most of the macular detachment and epithetlial cystic degenerateion of neurons recovered to normal. type - B ultrasound was performed in the first three months of treatment. The tumors were difficult to be detected in two cases, and four cases had a thickness of 0. 8 ～2.2mm. At the 6th month,the detection of tumors for the six cases showed normal results. PDT was used only once in the included six cases. Conclusion PDT and TTT therapeutic alliance for isolated choroidsal angioma is safe and effective at special position of eye ground. Each treatment showed its unlque adventages in this combination with a reduction of frequentcy and cost of expensive cost of PDT, and satisfying results of the shrink of the rumors and improvement or preservation of vision.
