Objective To evaluate the effect of uterine-reserved in the pelvio floor reconstruction,and select the best surgery for patients. Methods Through the observation and follow-up for 14 cases of uterine-reserved (experimental group) and 17 cases of uterine-removed (control group), to compare the information during the surgery, postoperative recovery, and quality of life of the two groups. Results The operation time, blood loss, postoperative discharge time, antibiotics application time and hospitalization time in experimental group were significantly lower than those in control group(P ＜ 0.05). The paruria, abdominal distention in experimental group [14%(2/14), 14%(2/14)] were significantly lower than those in control group [53% (9/17), 24% (4/17)] (P ＜ 0.05), and sexual satisfaction was significantly higher in experimental group than that in control group [71% (10/14) vs. 47% (8/17)] (P ＜ 0.05). There were no significant difference in pelvic pain, constipation of the two groups (P＞ 0.05). The POP-Q scores were normal after the operation both the two groups, each group beforeand after surgery compared the POP-Q score, were statistically significant (P ＜ 0.05). Conclusions Uterine-r eserved in the pelvic floor reconstruction can maintain the structural stability of the pelvic floor, and has the advantage of shorter operation time, less bleeding, more rapid recovery. Recent results are similar with hysterectomy, can reduce the risk of perioperative period to the elderly women.

AIM:By analyzing optical coherence tomography angiography (OCTA) characteristics of central serous chorioretinopathy (CSC) and comparing the differences of CSC between OCTA and indocyanine green angiography(ICGA), to explore if OCTA can substitute ICGA for diagnosis of CSC patients, and guide the treatment of photodynamic therapy (PDT).METHODS: We reviewed 30 eyes of 30 patients with CSC, who were diagnosed by fluorescein angiography (FFA) and ICGA at Beijing Tongren Eye Center from November 2015 to March 2016.All patients underwent best-corrected visual acuity (BCVA) measurement, intraocular pressure, slit-lamp examination, indirect ophthalmoscope, color fundus photography, FFA, ICGA and OCTA.FFA and ICGA were captured by Spectralis HRA + OCT (Spectralis HRA + OCT;Heidelberg Engineering, Heidelberg, Germany).OCTA was performed by RTVue XR Avanti device (OptovueInc, Fremont, CA) with 6mm×6mm Angio Retina mode.The software (version 2017.100.0.1;OptovueInc) automatically segmented the tissue into four layers, the characteristics of choriocapillaris layer were analyzed.At the same time, the differences between OCTA and ICGA images were compared among CSC patients.The maximum diameters and areas of both choroidal hyperperfusion in ICGA and high flow signal in OCTA were measured.Then, the paired t test was used to analyze the differences between the maximum diameter and area of OCTA and ICGA measurement.RESULTS: Among 30 cases, high blood flow signals of OCTA were clearly visible in 27 cases, namely the coarse grain region;the inner low flow signals surrounded by high blood flow signals were seen in 21 cases;the outer low flow signals surrounding high blood flow signals were seen in 7 cases.High blood flow signals of OCTA were corresponded with the choroidal hyperperfusion of ICGA images;among these 30 cases, there were low reflection shadows in choroidal hyperperfusion with ICGA for 22 cases, for 21 cases out of these 22 cases, low flow signals inside of high flow signals of OCTA could be seen;9 out of 30 cases, there were low reflection halo outside of choroidal hyperperfusion of ICGA, and 7 out of these 9 cases, low flow signals outside of high flow signals of OCTA could be seen;still for those 30 cases, leakage point in late ICGA could be seen with 14 cases, however, special flow signals in OCTA could not be seen for them.For ICGA, the maximum diameter of choroidal hyperperfusion was 1.589±0.295mm, whose area was 0.705±0.131mm2;while for OCTA, the maximum diameter of high flow signal was 1.576±0.293mm, whose area was 0.745±0.138mm2.By using paired t test, there was no statistical difference between the maximum diameter of choroidal hyperperfusion in ICGA and the maximum diameter of high flow signal in OCTA, nor difference between the area of ICGA and OCTA.CONCLUSION: The high flow signals can be clearly visible in OCTA, which are corresponded with choroidal hyperperfusion in ICGA.OCTA can substitute ICGA for diagnosis of CSC patients, and guide the treatment of PDT.

AIM: To evaluate the clinical feature of 9 patients harboring mitochondrial DNA ( mtDNA ) G11778A mutation with Leber hereditary optic neuropathy ( LHON) .
●METHODS: Nine LHON patients were enrolled and followed- up between 2012 to 2015 in Shenzhen Eye Hospital, clinical data were collected and analyzed.
●RESULTS: Six cases had maternal inheritance history ( 67%) . Three were sporadic cases. The patients aged from 9 to 43 years old, with average age of (22. 00±9. 42) years. Simultaneous onset with both eyes was in 5 cases (56%). Successively onset was in other 4 cases (44%). The ratio between male and female was 2:1. In the last follow-up, the visual acuity was finger counted in 2 eyes (11%), 0. 01-0. 1 in 12 eyes (67%), 0. 12-0. 4 in 2 eyes (11%),≥0. 4 in 2 eyes (11%). All patients had pale disc and clear boundary. ln the Humphrey visual field examination, 10 eyes had typically cecocentral or paracentral scotoma, 8 eyes had diffuse visual field defect.
●CONCLUSION: ln the 9 LHON patients with mtDNA G11778A mutation, simultaneous onset cases were more than successively onset cases within 1y cases. In most cases, LHON patients kept stable visual acuity. Rare cases had a raise in visual acuity within 1y. Majority patients had typically cecocentral or paracentral visual field scotoma. In the last stage of LHON, visual field present diffused defect. The secondary affected eye was similar performed defect as the former one.

A milk substitute for infant feeding has been prepared using(parts by weight): soybean flour 28.0, rice flour 45.0, egg-yolk powder 5.0, cane sugar 16.5, soybean oil 3.0, "fermented millet" 0.5, bone meal 1.5 and salt 0.5. Vanilla powder was added as the flavoring material.Soybean was soaked in water for 4 hrs., steamed under atmospheric pressure for 30 minutes and dried at 70-80℃ before milling. Bone meal was prepared from degelatinized animal bones, the by-product of a glue fatctory, Which have been treated with steam under 20-25 lbs. of pressure and repeatedly extracted with hot water for 10 hrs. "fermented millet" was prepared by innoculating the cooked millet with Eremothecium ashbyii as reported by Liu.The ingradients are mixed, pressed slightly into the form of small cubes, steamed and dried. When using, the proper number of cubes are mixed with the desired amount of water, cooked over a gentle fire and then served in the form of a thin paste.The proximate composition, the mineral and vitamin contents of the products, per 100 grams dry Weight, are as follows: protein 17.1 gms, fat 12.8 gms, carbohydrate 66.0 gms, crude fiber 0.82 gms, ash 3.25 gms, calcium 692 mgs, phosphorous(total) 330 mgs, (phytin)97 mgs, iron 5.9 mgs, thiamin 0.11 mgs, riboflavin 0.63 mgs, niacin 1.09 mgs, carotene 40.0 micro-gms, and energy 448 Cals.Aside from analyzing the product as well as the raw materials for the above nutrients, investigations were also made on the following subjects: determination of the essential amino acids, destruction of the trypsin inhibitor, availability of calcium and phosphorous, loss of thiamin, microbiological examination and soma physical changes of the product during storage.With respect to the adequacy of protein, 100 Cals. of the product would supply 3.8 gms of total protein which furnish all the essential amino acids to the amounts that a child would be able to obtain(per kilogram of body weight per day)from mother's milk.The product contains ample amounts of riboflavin, available calcium, phosphorous and iron to meet the diatary allowance of the infants. The amounts of thiamin and vitamin A are limited-the formet would satisfy only the minimum daily requirement while the latter is deficient by about 50％.Animal and human feeding experiments(to be published)indicated that this preparation promoted good growth not inferior to those fed on human or cow's milks. The cost of the new milk substitute is about 50％ less than the current prices of the present commercial products and about 80％ less than that of good grade cow's milk powder.

Objective To investigate the different responses of diaphragm and peripheral muscles to cisatracurium in rabbits.Methods 8 male New zealand rabbits were anaesthetized with pentobarbital,and then the diaphragm,tibialis anterior,soleus muscles,phrenic nerves,tibial nerve,and peroneal nerve were gently freeded.The muscles were secured to force displacement transducers,and the nerves were directly stimulated by electrodes with supramaximal square waves.The isometric force of twitch tention of each muscle was recorded.The cumulative dose-response technique was separately used for obtaining the ED50and ED95 values of the cisatracurium in each muscle.Results The muscle-relaxing of cisatracurium on the three muscles in were observed in a dose-dependent manner.The ED50 values and ED95 values were: diaphragm(39.3 ± 2.5)μg/kg and(75.7 ± 4.2)μg/kg,tibialis anterior(80.6 ± 7.5)μg/kg and(123.3 ±9.3)μg/kg,soleus(80.0 ± 7.1)μg/kg and(126.9 ± 9.4)μg/kg,respectively.It had significant difference between diaphragm vs tibialis or soleus,P ＜ 0.05.Conclusions The muscle relaxant effects of cisatracurium on diaphragm and peripheral muscles were different,and diaphragm was more sensitive than peripheral muscles.

ObjectivesTo investigate the composition of clinical classiifcation and pathological patterns and their rela-tionships and change in children with renal disease undergoing biopsy.MethodsA retrospective analysis of pathological and clinical data obtained from children (≤14 year) with renal disease undergoing biopsy from 1984-1997 and from 1998-2011 was performed.ResultsOne thousand four hundred and sixty-two children underwent renal biopsy in 28 years, and 1313 patients were recruited in this study, 824 males (62.8%) and 489 females (37.2%). The mean age was 9 years and 4 months at renal biopsy. There were 921 children (70.1%) with primary glomerular disease (PGD) and 312 children (23.8%) with secondary glomerular disease (SDG). The main clinical classiifcations of PGD were nephrotic syndrome (NS, 31.2%), isolated hematuria (IH, 16.1%), and acute glomerulonephritis (AGN, 11.0%). The main pathological patterns of PGD were IgA nephrop-athy (IgAN, 27.6%), minimal change disease (MCD, 24.0%), and mesangial proliferative glomerulonephritis (MsPGN, 16.9%). The main causes of SGD were lupus nephritis (LN, 40.7%), Henoch-Sch?nlein purpura nephritis (HSPN, 34.3%), and hepatitis B virus related glomerulonephritis (HBV-GN, 19.6%). In this 28 years, the composition of PGD was decreased, however, the compositions of SGD and other renal diseases were increased. Compared with 1984-1997, the pathological manifestations of IgAN, MCD and focal segmental glomeralosclerosis were increased, MsPGN, IgMN, and crescentic glomerulonephritis were decreased in 1998-2011. The difference was statistically significant (P<0.05). In SGD patients, HBV-GN was significantly decreased (P<0.05).ConclusionsPGD is the main disease in children undergoing renal biopsy. IgAN is the most common pathological pattern. NS is the most common clinical classiifcation. In this 28 years, the composition of PGD is decreased, SGD and other renal diseases are increased in children undergoing renal biopsy.

Objective To have a better understanding of the effort-reward imbalance for learning and learning burnout of high school students and their relationship. Methods A sample of 420 high school students was selected by stratified random sampling. Scales were used to study the effort-reward imbalance for learning and learning burnout and multiple linear regression analysis was used to study their relationship. Results A total of 387 high school students were actually investigated and 42.38% of which had effort-reward imbalance for learning. There were no significant differences in the rates of effort-reward imbalance for learning between students of different grades and between students of different homeplaces (P>0.05) . Female students had higher level of excessive input than males (P<0.05) . The average score of learning burnout was 56.93±13.22. There were no statistically significant differences in the scores of learning burnout between students of different genders and between students of different homeplaces (P>0.05) . The students who had effort-reward imbalance for learning scored higher in learning burnout than that who did not (P<0.05) . Senior Three students scored higher in learning burnout than Senior Two and One students (P<0.05) . The multiple linear regression analysis showed that learning reward and excessive input was both negatively correlated with learning burnout (all P<0.05) . Conclusion The high school students in Lishui City generally had the effort-reward imbalance for learning and learning burnout. learning reward and excessive input have effects on learning burnout.

OBJECTIVE The aim was to explore the clinical experiences and access the auditory performance and speech intelligibility of cochlear implantation in patients with inner ear malformations. METHODS Among 700 patients who received multi-channel cochlear implantation from 1997 to 2007 in Beijing Tongren Hospital, 108 patients were diagnosed with malformed inner ear. A retrospective study was performed about the surgical characteristics and the mapping characteristics after implantation. The long term follow-up of the rehabilitative efficacy will also be presented. RESULTS ①All patients restituted auditory after operation. ②After the regular rehabilitation, the long term follow-up of the auditory performance and speech intelligibility were very positive. Everyone has shown improved listening and communication skills evaluated by Categories of Auditory Performance and Speech Intelligibility Rating. ③Most of the children are studying or working and are actively involved in their local communities. CONCLUSION The cochlear implantation can be performed safely in patients with malformed inner ear. The results suggest that cochlear implantation could also provides long-term benefits to those malformed inner ear cases.
