AIM: To analyze the results of phacovitrectomy with internal limiting membrane(ILM) peeling to treat foveoschisis in ultra-high myopia.METHODS: Totally 32 eyes of 32 ultra-high myopia patients with foveoschisis were selected retrospectively.The preoperative refractive errors ranged from-12.00D to-20.00D with the mean of-15.78±2.16D.The best corrected visiual acuity(BCVA) were converted to LogMAR acuity, and the average BCVA was 4.1±0.4.Conventional phacovitrectomy with ILM peeling by ICG dying were performed.Gas tamponade were performed to end the operation.The BCVA and the foveoschisis cavity were observed by 1-9mo after the surgery, with the mean of 4.5mo.RESULTS: The foveoschisis cavity of 30 eyes were healed with BCVA increased and visual distortion alleviated distinctly (94%)(t=-7.91, P<0.05).CONCLUSION: Phacovitrectomy with ILM peeling is useful in treating foveoschisis in ultra-high myopia with visual function preserving.

OBJECTIVESTo investigate the histological changes in liver biopsy tissues taken from chronic hepatitis B patients with HBsAg and HBeAg positive and ALT abnormal after lamivudine therapy for one year.

METHODSLamivudine was given orally at the dose of 100 mg once a day for one year. 101 patients were enrolled into this open-label study. Paired liver biopsies from patients with hepatitis B before and after therapy with lamivudine were studied. Blinded biopsies were evaluated by a histopathologist and scored according to Knodell's histology activity index(HAI).

RESULTS53.5% (54/101), 51.5% (52/101) and 31.7% (32/101) patients had a reduction of their total hepatic HAI score, necroinflammation and fibrosis scores by >or=2 points or 1 points at the end of one year of lamivudine therapy, compared with their pretreatment values, respectively. There were significant reduction of HAI score, necroinflammation and fibrosis scores from 8.0+/-4.7 to 5.2+/-3.3 (t=7.358, P<0.01), from 5.9+/-3.8 to 3.6+/-2.5 (t=7.298, P<0.01), and from 2.1+/-1.2 to 1.6+/-1.2 (t=3.827, P<0.01), respectively. The histological improvement was independent on the HBeAg seroconvertion during the therapy.

CONCLUSIONSignificant improvement in liver histology, both necroinflammation and fibrosis, can be obtained in the majority of patients treated with lamivudine for one year.

Objective To evaluate the clinical and radiographic characteristics and function of erosive hand osteoarthritis (EOA) patients. Methods Data were obtained from 19 patients with EOA, including their social conditions, clinical conditions, radiographic scores and hand function evaluation. The number of hand osteoarthritis (HOA) patients was 312. The control group consisted of non-EOA patients with hand osteoarthritis with a ratio of 4:1 to EOA patients. A non-parameter test analysis was performed. All data were analyzed by SPSS 23.0 statistical analysis, t test, χ2 test, Fisher exact probility and Spearman's correlations analysis were used for statistical analysis. Results Totally data of 19 patients were collected. Eighteen were female. Onset age was (56±8). Average duration was 56 (12~120) months. FIHOA scores of all the EOA patients were at least 5. All the erosions of 39 joints were characteristically central and erosive changes in 7 joints (18%) showed up as gull-wing. Among 39 erosive joints, including 12 (31%) E and 27 (69%) R, 34 (87%) distal interphalangeal joints were involved. Data analysis found out that EOA patients had longer disease duration (Z=2.610, P=0.009), more severe K-L level (44 ±11 vs 26 ±7, t=7.134, P<0.01), higher AUSCAN total score (28±6 vs 21±7, t=3.781, P<0.01) and higher AUSCAN function score (18±6 vs 12±6, t=4.042, P<0.01). The differences of ESR and CRP were not significant between EOA and non-EOA patients. Conclusion Erosions seen in EOA patients are centrally located gull-wing in the DIP joints. EOA patients have longer duration, more severe radiographic damage and worse joint function.

Objective To investigate clinical manifestation of unspecified functional bowel disorder (UFBD), the features of coexistence with functional gastrointestinal disorder (FGID) and its relationship with psychological factors and sleep disturbance in the Chinese Army servicemen.Methodsc FGIDs were diagnosed based on the RomeⅢ Modular Questionnaire. The subjects were 189 servicemen with UFBD (UFBD group) and 372 without FGID (control group). All subjects completed symptom checklist 90 (SCL-90) and Pittsburgh Sleep Quality Index (PSQI) questionnaire.Results'Have to rush to the toilet when having a desire to defecate' was the most frequent symptom of UFBD (93.7%). More than one half of UFBD patients had the symptom 'a feeling of incomplete emptying as bowel movements' or 'straining during bowel movements'. Twenty-eight percent of UFBD subjects had combined FGID (namely cFGID). Among them, the most frequent was proctalgia fugax (7.9%), followed by cyclic vomiting syndrome (6.3%), functional fecal incontinence (6.3%), functional dyspepsia (4.8%) and belching (4.8%). The UFBD group scored significantly higher than the control group in the global severity index (GSI) and in all SCL-90 subscales (P<0.05). The scores of the four domains (sleep quality, sleep latency , sleep disturbance and daytime function disorder), total PSQI score and proportion of poor sleeping quality were significantly higher in the UFBD group than in the control group (P<0.05). The subjects scored significantly higher in combined FGID group than in UFBD group in GSI and in all of SCL-90 subscales, except for phobic anxiety subscales (P<0.05). However, there was no significant difference in each domain, total PSQI and proportion of poor sleeping quality between the cFGID group and UFBD group (P>0.05).ConclusionPathogenesis of UFBD may be closely correlated with psychiatric and psychological factors and sleep disturbance. cFGID are associated with an increased severity of psychopathological features.

OBJECTIVETo determine the anti-obesity effects of oolong tea on diet-induced overweight or obesity.

METHODSA total of 8 g of oolong tea a day for 6 weeks was ingested by 102 diet-induced overweight or obese subjects. The body fat level of the subjects was determined at the same time by taking body weight, height and waist measurements. The thickness of the subcutaneous fat layer was also determined on the abdomen 3 cm to the right of the navel by the ultrasonic echo method. On the other hand, effects of oolong tea ingestion on plasma triglyceride (TG) and total cholesterol (TC) were determined. Inhibitions of pancreatic lipase by oolong tea extract and catechins in vitro were also determined.

RESULTSA total of 70% of the severely obese subjects did show a decrease of more than 1 kg in body weight, including 22% who lost more than 3 kg. Similarly, 64% of the obese subjects and 66% of the overweight subjects lost more than 1 kg during the experiment, and the subcutaneous fat content decreased in 12% of the subjects. The correlation between weight loss and subcutaneous fat decrease in men (r=0.055) was obviously lower than that in women (r=0.440, P<0.01). Body weight loss was signifificantly related to the decrease of the waist size in men (r=0.730, P<0.01) and women (r=0.480, P<0.01). Also, the correlation between subcutaneous fat reduction and decreased waist size was signifificant in women (r=0.554, P<0.01), but not in men (r=0.050, P>0.05). Moreover, the plasma levels of TG and TC of the subjects with hyperlipidemia were remarkably decreased after ingesting oolong tea for 6 weeks. In vitro assays for the inhibition of pancreatic lipase by oolong tea extract and catechins suggest that the mechanism for oolong tea to prevent hyperlipidemia may be related to the regulative action of oolong tea catechins in lipoprotein activity.

CONCLUSIONSOolong tea could decrease body fat content and reduce body weight through improving lipid metabolism. Chronic consumption of oolong tea may prevent against obesity.

OBJECTIVETo investigate the effect of Guangdong Liangcha Keli on restraint stress-induced liver damage in mice.

METHODThirty-five male C57BL/6J mice of 7 weeks old were divided into 5 groups randomly with 7 mice in each group: normal group, restraint stress group, 250 mg kg(-1) Vitamin C, Guangdong Liangcha Keli 500 mg kg(-1) and 250 mg kg(-1). After 18 hr restraint stress, the ALT acitivity in plasma, MDA level in plasma and liver, GSH content, GSH-PX and GST activities, NO level and ORAC value in liver were determined.

RESULTCompared with restraint model group, Guangdong Liangcha Keli could markedly reduce ALT activity (92.75 +/- 1.91 vs 39.29 +/- 2.56, 32.69 +/- 1.46) U L(-1), and protect the liver damage induced by oxidative stress. In addition, Guangdong Liangcha Keli could effectively increase the ORAC value, GSH content, GSH-PX activity and GST activity and reduce the MDA level and NO level in liver.

CONCLUSIONOral treatment of Guangdong Liangcha Keli is found to reduce restraint stress-induced liver damage in terms of above mentioned biochemical parameters, and these protective effects may be related to its free radical scavenging activity and lipid peroxidation inhibitory effects.

To observe the antipyretic effect of Reduning injection (RDN) on lipopolysaccharide (LPS)-induced fever rats and its impact on centric fever medium. Rats were randomly divided into the blank control group, the model group, the Metamizole group, and high and low-dose RDN groups. Except for the blank control group, all of the rats were injected intraperitoneally with LPS (80 microg x kg(-1)) to observe their body temperature changes. The double-antibody sandwich ELSIA method was adopted to determine cAMP content in hypothalamus and MPO in lung tissues of fever peak rats. The high-dose RDN group can obviously reduce the temperature rise in fever rats, and cAMP and MPO content in hypothalamus. RDN showed significant antipyretic effect, which may be related with the reduction of cAMP content in hypothalamus and MPO in lung tissues.
