?METHODS:From January 2012 to December 2013, in 45 eyes of 45 high myopic patients with retinal detachment due to macular hole, 28 eyes were in group A of vitrectomy with posterior sclera reinforcement and 17 eyes were in group B of vitrectomy. Preoperative examinations included visual acuity, intraocular pressure, indirect ophthalmoscopy and OCT were performed. ln follow - up 6 to 12mo, postoperative examinations of visual acuity, OCT were performed and effects of retinal reattachment and macular hole closure were compared between the two groups.
?RESULTS: ( 1 ) Postoperative examinations: visual acuity was 1. 19±0. 39 in group A and 1. 51±0. 34 in group B. The differences were statistically significant(P<0. 05). (2) The retinal reattachment rate was 100% in group A and 88. 24% in group B. There was no statistical significance between them(P>0. 05). (3) The macular hole closure rate was 82% in group A and 53% in group B. The differences were statistically significant(P<0. 05).
? CONCLUSlON: The treatment of vitrectomy with posterior sclera reinforcement is safe and feasible, which could improve visual acuity and increase the rate of macular hole closure in treating retinal detachment due to macular hole in high myopia.

AlM: To evaluate the therapeutic effects and safety of femtosecond laser assisted penetrating keratoplasty ( FS-PKP) .
METHODS: ln the retrospective case series study, 46 cases ( 48 eyes ) with FS- PKP holds were analyzed. Preoperative best corrected visual acuity ( BCVA) was 2. 35 ± 1.01 (with a standard logarithmic eye chart). Opacities were all from epithelium to endothelium, including keratoconus, keratolukoma and corneal scarring etc. The full-thickness corneal donor-recipient grafts in different diameter and incision kerfangle were made by femtosecond laser in keratoplasty. The patients were treated according to the conventional penetrating keratoplasty after surgery. Evaluation indexes included preoperative and postoperative 1, 6, 10mo uncorrected visual acuity (UCVA), BCVA, corneal astigmatism (CA) and surgical complications. Forty-three cases (44 eyes) with traditional PKP were as control group. The data of two groups were analyzed by mean comparison of two groups and Chi-square test in SPSS 18. 0.
RESULTS: All the operations were completed successfully, postoperative visual acuity of all patients had different degrees of increase. Comparison with the postoperative UCVA of traditional PKP surgery, UCVA was 3. 48 ± 0. 43 and 2. 97 ± 1. 14 at 1mo after operation, respectively, with statistically significant difference ( P=0. 009). The UCVA was 3. 86±0. 25 and 3. 74±0. 73 at 3mo after operation, respectively; the UCVA was 4. 04 ± 0. 23 and 3. 98 ± 0. 29 at 6mo after operation, respectively, with no statistically significant difference (P=0. 146, P=0. 56). ln FS-PKP group, BCVA was better than traditional PKP surgery group, with statistically significant difference ( P=0. 002 ). While there had no statistically significant difference between two groups of BCVA at 6, 10mo after operation (P6mo =0. 132, P10mo =0. 47). The incidence of complication of FS-PKP surgery, such as postoperative astigmatism, postoperative intraocular pressure and postoperative incision dehiscence were significantly lower than the one of traditional PKP surgery(P<0. 05).
CONCLUSlON:Compared with traditional penetrating keratoplasty, FS-PKP provides significantly faster visual recovery in the early postoperative period, and induces significantly less corneal astigmatism and lower incidence of complication. lt reflected the clinical superiority of this new technology .

OBJECTIVETo investigate the tongue manifestation features of sexually transmitted and intravenous drug use spread HIV infected population in Xinjiang.

METHODSRecruited were 990 HIV infected subjects in Xinjiang from May 2011 to March 2012, who were assigned to the intravenous drug use spread HIV infected (498 cases) and the sexually transmitted (492 cases). By using tongue figure shoot combined with analyses of experts, tongue manifestations were analyzed and compared between the sexually transmitted and the intravenous drug use spread from four aspects, i.e., the tongue color, the tongue shape, the fur color, and the fur property.

RESULTSCompared with the sexually transmitted population, red tongue, fissured tongue, yellow fur, thick fur, eroded fur, deficiency of fur fluid were more often seen, showing statistical difference (P < 0.05). Compared with the intravenous drug use spread population, pale tongue, white fur, and thin fur were more often seen, showing statistical difference (P < 0.05).

CONCLUSIONSThe tongue manifestations of the intravenous drug use spread HIV population reflected inner exuberance of evil toxin and heat impairing qi and yin. Compared with the intravenous drug use spread population, the attack of HIV infection was more hiding in the sexually transmitted population, with milder internal injury. Their Wei-qi was not damaged and no obvious change occurred in the tongue figure.

Background The diagnosis of central serous chorioretinopathy (CSC) is mainly dependent onfluorescine fundus angiography (FFA). However, the combination of optical coherence topography (OCT) with FFA offers a new approach to the research of the pathogenesis of CSC. Objective This clinical study was designed to study the combined application of the FFA and OCT for the research of the pathogenesis of central serous chorioretinopathy (CSC). Methods Forty-four eyes of 44 patients with CSC were included in this study with 36 cases of males and 8 cases of female. The patients were aged 39.3 ± 5.3 years and the visual acuity was 0. 64 ±0. 27. FFA and OCT examinations were performed in all patients and the FFA images were imported into the Topcon 3D OCT 1000 device to locate the conformity of OCT lesions with the leakages of FFA. The neuroepithelial layer thickness at the fovea and the height of the neuroepithelial layer detachment were measured using 3-D OCT. Results OCT showed serous REP detachment in 34 eyes (77.3%) and rough surfaces of RPE in 10 eyes (22. 7% ). In thirtyfour eyes with RPE detachment, the OCT lesions and FFA leakage spots conformed to the same locations in 31 eyes, but the other three eyes did not. The mean foveal neuroepithelial thickness was (138.5±19.4) μm in CSC eyes and that of normal eyes was ( 131.35±5. 01 ) μm ,showing a significant difference between them( t=0. 39 ,P＞0. 05 ). The mean height of neuroepithelial detachment was (263.3 ± 126.7 ) μm in CSC eyes. Conclusion RPE detachment occurs in CSC eyes and further induces macular neuroepithelial detachment. Leakage lesion of fluorescine corresponds to RPE detachment. CSC without RPE detachment may be related to the increase in RPE permeability. OCT can accurately measure the thickness of the macular neuroepithelial layer and the height of the neuroepithelial detachment.

OBJECTIVETo analyse the features of 8 cases of Bcr(+) thrombocytosis.

METHODSThe clinical and hematological features and therapeutic outcomes were studied retrospectively in 8 Bcr(+) thrombocytosis and compared with essential thrombocytosis (ET) and chronic myeloid leukemia-chronic phase thrombocytosis (CML-CP-T). BCR-ABL fusion gene was detected with PCR.

RESULTS(1) Except for the presence of BCR-ABL fusion gene, there was no significant difference in clinical and hematological features and therapeutic outcomes between thrombocytosis with or without BCR-ABL. (2) The Bcr(+) thrombocytosis differed from CML-CP-T in the following aspects: female predominance, milder or no splenomegaly, peripheral leukocytes count < 40 x 10(9)/L, less or no basophilia and fewer immature granulocytes in peripheral blood, bone marrow granulocytic and/or megakaryocytic lineage hyperplasia, normal or increased neutrophil alkaline phosphatase score and less blastic transformation.

CONCLUSIONBcr(+) thrombocytosis may be considered as a new member of chronic myeloproliferative diseases, a variant of essential thrombocythemia.

Abstract: Objective To analyze the effect of nutrition package on the nutritional status and prevalence of children in rural areas of Hainan Province, and provide scientific basis and suggestions for further improving the nutritional and health status of children in this region. Methods　Four cities and counties were randomly selected as the intervention group, and four cities and counties matched with the intervention group in terms of population, economy, social culture, maternal and child health work foundation of township health centers, physical nutrition and health status were selected as the control group.With the combination of monitoring and prospective cohort study, infants in the intervention group and the control group were studied from June 1, 2020, and they were intervened for 12 months with supplementary food nutrition package. Before and after intervention, the nutrition and health status of infants aged 6-24 months in the intervention group and the control group were investigated to evaluate the nutritional and health effects of supplementary food nutrition package for infants aged 6-24 months in rural Hainan Province. Results　A total of 999 infants were investigated, including 427 in the intervention group and 572 in the control group. After 12 months of nutritional intervention, there was no significant difference in weight-for-age Z-score (WAZ) and height-for-age Z-score (HAZ) and weight-for-height Z-score (WHZ) between the intervention group and the control group (P>0.05). The rate of emaciation of the intervention group was 1.64%, which was significantly lower than 3.67% of the control group (P<0.05). There were no significant differences in the rate of growth retardation (2.81% and 3.32%, respectively) and underweight (0.47% and 1.92%, respectively) between the intervention group and the control group (P>0.05). The rate of respiratory infection and diarrhea in the intervention group were 9.13% and 1.17%, which were significantly lower than corresponding 23.25% and 3.15% in the control group (P<0.05). The hemoglobin of the intervention group and the control group were 117.24 g/L and 114.51 g/L respectively, and the rates of anemia were 11.11% and 22.84% respectively, the differences were statistically significant (P<0.05). Conclusions　The intervention of nutrition package in rural areas of Hainan Province has achieved the expected results, and supplementary food nutrition package has reduced the incidence of malnutrition and respiratory infection and diarrhea in recent two weeks in infants and anemia to a certain extent. We should attach great importance to the supplementary nutrition package for right-age children and promote the growth and health of children in rural areas through supplementary nutrition package, and continuously improve the nutrition and health level of children in Hainan Province.

BACKGROUNDThe prognosis for patients with gastric cancer and synchronous liver metastases is very poor. However, a standard therapeutic strategy has not been well established. The clinical benefit and prognostic factors after hepatic surgical treatment for liver metastases from gastric cancer remain controversial.

METHODSRecords of 105 patients who underwent gastrectomy regardless of hepatic surgical treatment for gastric cancer with synchronous liver-only metastases in our center between 1995 and 2010 were retrospectively reviewed.

RESULTSThe overall survival rate for the 105 patients was 42.1%, 17.2%, and 10.6% at 1, 2, and 3 years, respectively, with a median survival time of 11 months. Multivariate survival analysis revealed that the extent of lymphadenectomy (D) (P < 0.001), lymph node metastases (P < 0.001), extent of liver metastases (H) (P = 0.008), and lymphovascular invasion (P = 0.002) were significant independent prognostic factors for survival. Among patients who underwent D2 lymphadenectomy, those who underwent hepatic surgical treatment had a significantly improved survival compared with those who underwent gastrectomy alone (median survival, 24 vs. 12 months; P < 0.001). However, hepatic surgical treatment was not a prognostic factor for patients who underwent D1 lymphadenectomy (median survival, 8 vs. 8 months; P = 0.495). For the 35 patients who underwent gastrectomy plus hepatic surgical treatment, D2 lymphadenectomy (P < 0.001), lymph node metastases (P = 0.015), and extent of liver metastases (H1 vs. H2 and H3) (P = 0.017) were independent significant prognostic factors for survival.

CONCLUSIONSD2 lymphadenectomy plus hepatic surgical treatment may provide hope for long-term survival of judiciously selected patients with hepatic metastases from gastric cancer. Patients with a low degree of lymph node metastases and H1 liver metastases would make the most appropriate candidates. However, if D2 dissection cannot be achieved, hepatic surgical treatment is not recommended.
