Tianjin Medical Journal 2016;44(4):466-469
Objective To analyze the differences of positive detection rate and copy number of human papillomavirus (HPV) DNA and E6/E7 mRNA between different grades of cervical lesions, and evaluate their clinical values in early screen?ing of cervical cancer. Methods The cervical exfoliated cell samples from 154 women undergoing biopsy examination and 32 objects undergoing hysterectomy (control group) were collected in Tianjin Central Hospital of Gynecology Obstetrics in 2014. According to the pathological results of cervical biopsy, 154 samples were divided into low-grade squamous intraepi?thelial lesion group (LSIL, n=51), high-grade squamous intraepithelial lesion group (HSIL, n=71), and squamous cell carci?noma group (SCC, n=32). HPV DNA was tested with hybrid capture technology, and E6/E7 mRNA was detected with fluores?cence quantitative hybridization. Immunohistochemistry was performed by detecting E6/E7 protein in all patients after sur?gery or cervical biopsy. Results Combined results of HPV DNA and E6/E7 mRNA demonstrated that the positive detection rate was significantly lower in control group than that of all levels of lesion groups (P<0.05). The copy number of high risk HPV E6/E7 mRNA was significantly increased with the aggravation of lesions (P<0.05), whereas no difference was found in that of HPV DNA. Compared with the normal control and low-grade squamous intraepithelial lesion group, cervical cancer patients with mRNA copies > 10 000 E6/E7 were significantly increased in high-grade squamous intraepithelial lesion group. Immunohistochemical results showed that the positive detection rate of E6/E7 was significantly lower in control group than that of all levels of lesion groups (P<0.05). The positive rate of E6/E7 was significantly higher in the high-grade squa?mous intraepithelial lesion group than that of low-grade group (P<0.05). Conclusion HPV infection is closely related to cervical abnormalities, which is one of effective measures for early screening of cervical cancer. The negative result of HPV DNA is very helpful to exclude the cervical abnormality, whereas the positive detection of mRNA has great value in predict?ing the disease. Combined results of positive detection and copy number make a comprehensive evaluation for the risk of cer?vical lesions.

Objective To evaluate the efficacy of the soft-shell technique with domestic materials during the cataract phacoemulsification. Methods Eighty-two eyes of 76 patients with the mature cataract phacoemulsification were divided into 3 groups randomly, including 28 eyes using the soft-shell technique with sodium tvlose and sodium hyaluronate (the domestic group),and 28 eyes using DuoVisc (Viscoat+ProVisc) (the import group), and 26 eyes using sodium hyaluronate (the common group). Results The average naked vision was 0.50 ± 0.22,0.51 ± 0.27,0.27 ± 0.21 respectively on the first day after operation.There was no signiticant difference between the domestic group and the import group (P>0.05 ), while the first two groups and the common group had significant difference (P < 0.05). The average naked vision was 0.61 ± 0.17,0.63 ± 0.18,0.58 ± 0.18 respectively 7 days after operation. There was no statistical difference among the three groups (P > 0.05 ). The rate of corneal endothelial cells 1 month after operation was 7.1% in the domestic group,7.0% in the import group and 15.9% in the common group. It was clear that the rate in the domestic group and the import group was much lower than that in the common group. Meanwhile, the difference existed statistically between the two groups and the common group (P < 0.01 ). However, the difference between the domestic group and the import group had no statistical significance. Conclusion The soft-shell technique with domestic materials is as safe and effective as that with the import materials in protecting the corneal endothelial cells during the cataract surgery in patients with the mature cataract.

Objective To analyze the reasons of early complications in anterior cervical spine surgery and its management. Methods Between Jan 1992 and Dec. 2003, 412 patients underwent anterior cervical surgery. There were 308 males and 104 females with an average age of 45.6 years (18-76). The di-agnosis of these patients included 258 of cervical spondylosis, 138 of cervical injury, 8 of cervical spinal tu-mor and 8 of tuberculosis of cervical spine. The medical history was from 4 hours to 20 years with an aver-age duration of 548 days. Among 412 patients, there were 58 cases (14.1%) with complete paraplegia, 192 cases (46.6%) with incomplete paraplegia and 162 cases without neurological deficits. Anesthesia used in this group of patients were local in 35, cervical plexus block in 52, local associated with cervical plexus block in 6, general in 318 and general associated with cervical plexus block in 1. Three surgical procedures were performed: 1) anterior decompression and interbody fusion with autogenous iliac crest in 33 cases; 2) anterior decompression and interbody fusion with threaded fusion cage in 32 cases; 3) anterior decompres-sion, interbody fusion with autogenous iliac crest and plate fixation in 347 cases. Results Fifty-one early complications occurred in 42 patients and the incidence was 12.37%. 28 patients (6.8%) had complications directly related to the procedure which included superior laryngeal nerve injury in 5, recurrent laryngeal nerve injury in 4, migration of bone graft in 2, infection or haematoma in 4, deterioration of neurological function in 5,nerve root injury in 2, loosening of screw or plate fixation in 2 and esophageal fistula in 1. 23 cases (5.08%) had early complications indirectly related to the procedure. Conclusion In order to reduce the incidence of early complications in anterior cervical spine surgery, make familiarization with anatomy, improvement of surgical skill as well as appropriate perioperative management are essential in anterior cer-vical spine surgery.

We evaluated the effect of Tu-Chung (Eucommia ulmoides OLIV.) extract on anabolic action in castrated exercise and non-exercise rats in which the effects of male sex hormone from the testis were excluded. Castration was performed on 32 male Wistar rats aged 4 weeks. The rats were then divided into 4 groups: a non-exercise group treated with Tu-Chung extract (non Ex. Tu-chung G, n = 8), on exercise group treated with the extract (Ex. Tu-Chung G, n = 8), a non-exercise control group not treated with the extract (non Ex. Cont. G, n8), = and an untreated exercise control group (Ex. Cont. G, n=8) .
The Tu-Chung extract was administered orally at a dose of 1g/kg body weight once daily for 4 weeks. Distilled water was given by a similar method to the control groups. As the exercise load, the rats exercised on an animal treadmill at a starting speed of 20 m/min with an increase of 10 m/min every week for 30 min without rest daily for 4 weeks.
The following results were obtained:
1. The relative weight of the adrenal gland (gland weight/100 g body weight ) after 4 weeks was significantly higher in the non Ex. Tu-Chung G than in the non Ex. Cont. G (p<0.001) and in the Ex. Tu-Chung G than in the Ex. Cont. G or the non Ex. Cont. G (p<0.001 each) .
2. The relative weight of the kidneys (kidney weight/100 g body weight) after 4 weeks was significantly higher in the non Ex. Tu-Chung G than in the non Ex. Cont. G (p<0.001) and was slightly higher in the Ex. Tu-Chung G than in the Ex. Cont. G.
3. The relative weight of the musculus levator ani (muscle weight/100g body weight) after 4 weeks was significantly higher in the non Ex. Tu-Chung G than in the non Ex. Cont. G (p<0.001) and also in the Ex. Tu-Chung G than in the Ex. Cont. G (p<0.001) .
4. The 17-KS level in a 24h urine sample after 4 weeks was significantly higher in the non Ex. Tu-Chung G than in the non Ex. Cont. G or the Ex. Tu-Chung G (p<0.001 each) and also in the Ex. Tu-Chung G than in the Ex. Cont. G (p<0.001) .
5. The total urinary nitrogen level after 4 weeks was significantly lower in the non Ex. Tu-Chung G than in the non Ex. Cont. G (p<0.001) or the exercise group treated with the extract (p<0.05) and also in the Ex. Tu-Chung G than in the Ex. Cont. G (p<0.05) .
These results suggest that administration of Tu-Chung extract significantly increases the relative weight of the adrenal gland, enhances androgen secretion from the reticular layer of the adrenal cortex, and promotes protein anabolic action in castrated rats. In addition, this extract appears to increase the adaptation ability of the adrenal cortex to the stress caused by exercise.

This study examined the secretion capacity of the gonadal and adrenal cortex systems and the morphology of the adrenal cortex in male rats treated with Tu-chung (Eucommia ulmoides OLIV) extract, the main component of Tu-chung extract, geniposide, or both agents during exercise load testing.
Twenty-four 4-week-old male Wistar rats were used. The rats were divided into four groups : those treated with Tu-chung extract and geniposide (n=7), those treated with Tu-chung extract (n=6), those treated with geniposide (n=7) and a control group treated with distilled water. The dose of each agent was 0.1 ml/100g body weight. The agents were administered orally for 25 days. For the exercise load test, a treadmill for small animals was used, with a tilting angle set at 0. Exercise load testing was performed for 30 min (2-min warm up and 28-min running) daily for 25 days. The running speed was 20 m/min for the first 5 days, and then increased by 5 m/min every 5 days.
The following results were obtained.
1. The relative weight of the adrenal gland (gland weight/100 g body weight) in the group treated with Tu-chung extract and geniposide was significantly higher than that in the group treated with geniposide or the control group (p<0.01) . The relative weight of the adrenal gland in the group treated with Tu-chung extract was significantly higher than that in the group treated with geniposide or the control group (p<0.01, p<0.001) . Furthermore, the relative gland weight in the group treated with geniposide was significantly higher than that in the control group (p<0.05) .
2. In the group treated with Tu-chung extract and geniposide, the group treated with Tu-chung extract and the group treated with geniposide, the relative gland weight of the testis (testis weight/100g body weight) was significantly higher than that in the control group (p<0.001) . However, there were no significant differences among the three groups.
3. The 24-h urinary excretion of 17-ketosteroid (17-KS) in the group treated with Tu-chung extract and geniposide was significantly higher than that in the group treated with Tu-chung extract, the group treated with geniposide or the control group (p<0.01, p<0.01, p<0.001) . In the group treated with geniposide, the 24-h urinary excretion of 17-KS was significantly higher than that in the control group (p<0.05) .
4. In the three groups treated with Tu-chung extract and/or geniposide, serum testosterone levels were significantly higher than those in the control group (p<0.001, p0.05, p<0.05) .
5. Concerning the morphology of the adrenal cortex, the thickness of the reticular layer of the adrenal cortex was most markedly increased in the group treated with Tu-chung extract and geniposide, followed in order by the group treated with Tu-chung extract, the group treated with geniposide and the control group.
Administration of Tu-chung extract and the main component of Tu-chung extract, geniposide, during exercise load testing significantly increased the weights of the adrenal gland and testis, and promoted testosterone secretion in the adrenal cortex reticular layer and testis.
These findings suggest that geniposide plays an important role in the pharmacological action of Tu-chung.
