OBJECTIVE:
To compare the femoral and tibial tunnel positions of anterior cruciate ligament reconstruction using the modified transtibial (MTT) technique and anteromedial (AM) portal technique.
METHODS:
Between January 2017 and September 2020, 78 patients with anterior cruciate ligament rupture underwent single-bundle reconstruction with the modified transtibial technique in 39 cases (group MTT) and through anteromedial approach in 39 cases (group AM). There were 25 males and 14 females in group MTT, with an average age of (37.0±2.3) years old; 27 males and 12 females in group AM, with an average age of (37.5±2.2) years old. CT scan of the affected knee was conducted one week after the surgery to measure and compare the femoral tunnels positioning (Fx, Fy), tibial tunnels positioning in the frontal plane(Tx1), tibial tunnels positioning in the sagittal plane (Ty1), and tibial tunnels positioning in the axial plane (Tx2, Ty2) in patients undergoing anterior cruciate ligament reconstruction through Mimics software.
RESULTS:
Three-dimensional CT reconstruction after the surgery showed that the average Fx and Fy were(25.2±2.1)% and (34.9±3.0)% respectively and the Tx1 and Ty1 were (45.5±3.3)% and (44.7± 3.0)% respectively, while the Tx2 and Ty2 were (47.0±3.0)% and (39.9±4.2)% respectively in group MTT. In group AM, the average Fx and Fy were (26.0±2.0)% and (36.1±3.9)% respectively and the Tx1 and Ty1 were (46.5±3.1)% and (45.6± 3.1)% respectively, while the Tx2 and Ty2 were (47.4±2.5)% and (39.6±3.9)% respectively. There were no statistically significant differences in the femoral and tibial tunnels between the two groups (
CONCLUSION
Both the MTT and AM technique can achieve good anatomical positioning of the femoral and tibial tunnels, without significant differences in the positioning of the bone tunnels.

OBJECTIVE:To virtually screen potential α-glycosidase inhibitor ingredients from C. mori and F. mori,and to pro-vide reference for finding out new typeα-glycosidase inhibitor ingredient. METHODS:Surflex-Dock module of Sybyl-x 2.0 molecu-lar simulation software was used to perform the docking of small molecule compound,which was from the ingredients of C. mori and F. mori as ligand stated in literatures,with α-glycosidase. Total score of affinity scoring function was equal to 7 as the thresh-old value,to judge potential α-glycosidase inhibitor ingredient in C. mori and F. mori. RESULTS:After 70 small molecule com-pounds docked with α-glycosidase, 10 compounds showed binding activity (Total score≥7.00). Among them, moracin M-3′-O-β-D-glucopyranoside,5,7,2′-trihydroxyflavanone-4′-O-β-D-glucoside,mulberroside A,resveratrol-4,3′-di-O-β-D-gluco-pyranoside and 1,4-dideoxy-1,4-imino-(2-O-β-D-glucopyranosyl)-D-arabinitol had higher binding activity with α-glycosidase(Total score>8.00). CONCLUSIONS:Multi-constituents of C. mori and F. Mori show potential α-glycosidase inhibitory activity. The method is a kind of highly targeted,rapid and efficient approach to discover α-glycosidase inhibitor from traditional Chinese medi-cine.
3.Physiological mechanisms of prostaglandin analogues on lowing intraocular pressure
International Eye Science 2017;17(5):884-887
Pathological elevation of intraocular pressure(IOP)is the most prevalent risk factor in the development and progress of glaucoma. Up to date, all treatments for glaucoma are aimed to lower IOP through surgeries and drugs. Prostaglandin analogues are the first-line IOP-lowing drugs for glaucoma due to their ability to reduce IOP. Enough evidences have suggested that they increase aqueous humor outflow through uveoscleral pathway. More recently, people found that bimatoprost was able to increase aqueous humor outflow through trabecular meshwork-Schlemm's canal pathway. Nowadays, a large number of studies are performed to study the mechanism of prostaglandin analogues on lowing intraocular pressure.

Objective:
To investigate the relationship between enteral nutrient albumin supply and prognosis in patients with mechanical ventilation.
Methods:
The clinical data of 418 mechanically ventilated patients receiving enteral nutrition support treatment in intensive care unit (ICU) of the First Hospital of Jiaxing from January 2016 to June 2019 were retrospectively analyzed. According to whether the daily albumin supply was up to standard, the patients were divided into the standard group (albumin supply was ≥1.2 g·kg-1·d-1) and the non-standard group (albumin supply was < 1.2 g·kg-1·d-1). Prealbumin, transferrin levels before and after treatment, 28-day mortality, mechanical ventilation time and the length of ICU stay were compared between the two groups.
Results:
A total of 418 patients were included, including 225 in the standard group and 193 in the non-standard group. There were no significant differences in gender, age and disease composition between the two groups, and the baseline data were comparable. There was no significant difference in daily calories between the standard group and the non-standard group (kJ/d: 119.73±31.55 vs. 110.05±28.98,

OBJECTIVETo explore the origin of a supernumerary small marker chromosome (sSMC) in a fetus, and to assess the feasibility of single nucleotide polymorphism array (SNP-array) for prenatal diagnosis.
METHODSThe fetal sample was subjected to karyotyping analysis. The identified sSMC was subjected to genome-wide scan using a SNP microarray chip. The results were validated with fluorescence in situ hybridization (FISH).
RESULTSThe karyotype of the fetus was determined as 47,XX,+mar, which was verified by SNP microarray chip analysis as a 34.6 Mb duplication in 12p13.33p11.1. FISH analysis confirmed that the sSMC has originated from chromosome 12p.
CONCLUSIONThe karyotype of the fetus was determined as 47,XX,+i(12)(p10). Tetrasomy 12p is reported to be a marker for Pallister-Killian syndrome, which may result in multi-system anomalies. SNP-array analysis can simultaneously detect microdeletions and microduplications, which may be used for prenatal diagnosis of suspected cases.

OBJECTIVETo observe the effect of core strength training on knee joint function and postural stability after anterior cruciate ligament reconstruction (ACLR).
METHODSA total of 80 ACLR patients were randomly allocated into conventional rehabilitation training group and core strength training group from May 2013 to May 2015 with 40 patients in each group. The patients in conventional rehabilitation training group underwent conventional ACLR rehabilitation training, in which 28 males and 12 females. The mean age was(30.5±5.2) years old(ranged, 22 to 42 years old). The mean BMI was(23.8±2.4) kg/m²(ranged, 18.2 to 25.9 kg/m²). Thirty patients had injuries on the dominant side and 10 patients had injuries on the non-dominant side. The core strength training group received conventional ACLR rehabilitation training and core strength training, in which 31 males and 9 females. The mean age was(31.1±4.8) years old(ranged, 21 to 45 years old). The mean BMI was(24.1±2.7) kg/m²(ranged, 18.5 to 26.1 kg/m²) . Twenty-seven patients had injuries on the dominant side and 13 patients had injuries on the non-dominant side. The Lysholm score, tibial anterior transition measured by KT-1000 before and after treatment, and the Star Excursion Balance Test results after treatment were compared between the two groups.
RESULTSSix months after rehabilitation training, the tibial anterior transition of the conventional rehabilitation training group and the core strength training group were(3.4±1.0) mm and(3.3±1.2) mm respectively, which were less than(12.1±1.8) mm and(12.5±2.0) mm before treatment. But there was no significant difference in anterior tibial translation between two groups(>0.05). The Lysholm score of the conventional rehabilitation training group and the core strength training group were 91.8±4.3 and 92.1±3.9 individually, which were higher than 69.2±5.8 and 70.2±5.1 before treatment. But there was no significant difference in Lysholm score between two groups(>0.05). Six months after rehabilitation training, the results of Star Excursion Balance Test showed the reach distance with the support in the injured side and healthy side in the core strength training group were greater than that of the conventional rehabilitation training group in the eight directions(<0.05).
CONCLUSIONSThe core strength training could improve the dynamic balance of ACLR patients.

OBJECTIVE:
To investigate the relationship between enteral nutrient albumin supply and prognosis in patients with mechanical ventilation.
METHODS:
The clinical data of 418 mechanically ventilated patients receiving enteral nutrition support treatment in intensive care unit (ICU) of the First Hospital of Jiaxing from January 2016 to June 2019 were retrospectively analyzed. According to whether the daily albumin supply was up to standard, the patients were divided into the standard group (albumin supply was ≥ 1.2 g×kg-1×d-1) and the non-standard group (albumin supply was < 1.2 g×kg-1×d-1). Prealbumin, transferrin levels before and after treatment, 28-day mortality, mechanical ventilation time and the length of ICU stay were compared between the two groups.
RESULTS:
A total of 418 patients were included, including 225 in the standard group and 193 in the non-standard group. There were no significant differences in gender, age and disease composition between the two groups, and the baseline data were comparable. There was no significant difference in daily calories between the standard group and the non-standard group (kJ/d: 119.73±31.55 vs. 110.05±28.98, P > 0.05), but the daily albumin supply of the standard group was significantly higher than that of the non-qualified group (g×kg-1×d-1: 1.38±0.83 vs. 0.95±0.75, P < 0.05). There was no significant difference in the levels of prealbumin, transferrin between the two groups before treatment. The levels of prealbumin, transferrin in standard group and non-standard group were significantly higher after treatment than before [prealbumin (mg/L): 188.53±69.25 vs. 119.44±57.62, 145.18±56.92 vs. 108.81±69.50; transferrin (g/L): 2.99±0.87 vs. 1.85±0.76, 2.09±0.81 vs. 1.52±0.76, all P < 0.05]. Moreover, prealbumin and transferring in the standard group were further improved than the non-standard group [prealbumin (mg/L): 188.53±69.25 vs. 145.18±56.92, transferrin (g/L): 2.99±0.87 vs. 2.09±0.81, both P < 0.05]. In addition, mechanical ventilation time, the length of ICU stay of the standard group were significantly shorter than those of the non-standard group (hours: 147.2±7.5 vs. 216.6±8.2, 198.8±9.5 vs. 295.4±8.9, both P < 0.05), but there was no statistically significant difference in 28-day mortality [11.56% (26/225) vs. 15.03% (29/193), P > 0.05].
CONCLUSIONS
Under the condition of standard enteral nutritional calories, increased of the albumin supply can improve the clinical nutritional status of patients with mechanical ventilation, shorten mechanical ventilation time and hospital stay.

Chinese Journal of Medical Genetics 2019;36(2):147-150
OBJECTIVE:
To explore the molecular basis for an individual with postnatal deafness and provide genetic counseling for her family.
METHODS:
Following extraction of genomic DNA from peripheral blood samples, 127 genes associated with deafness were subjected to targeted capturing and next generation sequencing. Suspected mutation was verified by Sanger sequencing.
RESULTS:
The proband was found to carry a homozygous c.1893C>A mutation in the TECTA gene, which is located in the tectorial membrane of inner ear and may cause premature termination of translation of TECTA protein. In addition, two heterozygous mutations, c.13010C>T and c.12790G>A, were found in the USH2A gene. Whilst the former is likely to be pathogenic, the latter has unknown clinical significance. Further analysis suggested that all three mutations have derived from the parents of the proband.
CONCLUSION
The homozygous c.1893C>A mutation of the TECTA gene probably underlies the proband's hearing loss which conformed to an autosomal recessive inheritance.

Objective To investigate the influence of acupuncture on learning and memorial function and the expression of BDNF in prefrontal cortex of rats with sleep deprivation (SD), for providing theoretical evidence for treating sleep deprivation with acupuncture.Method Sixty Wistar rats were randomly divided into a control group, a model group, and an acupuncture group, 20 rats in each group. SD models were established by the modified multiple platform methods; the acupuncture group was intervened by acupuncture at Shenmen (HT 7); while the control group was left intact. Respectively after SD for 24 h and 72 h, the learning and memorial function was tested by using Morris water maze. Ten the rats were sacrificed to collect brain for detecting the expression of BDNF in prefrontal cortex via immunohistochemical method.Result The body weight, learning and memorial function, and the expression of BDNF in prefrontal cortex of the acupuncture group and model group were significantly different from those of the control group after SD for 24 h and 72 h (P<0.05). The learning and memorial function of the acupuncture group was significantly different from that of the model group after SD for 24 h and 72 h (P<0.05). The body weight and expression of BDNF in prefrontal cortex of the acupuncture group were significantly different from those of the model group after SD for 72 h (P<0.05).Conclusion Acupuncture can obviously improve the decline of the function of learning and memory of the SD rats, and also up-regulate the declined expression of BDNF in prefrontal cortex caused by SD.
