Hepatocellular carcinoma (HCC) is one of leading causes of death in the world. Although various treatments have been developed, the therapeutic side effects are far from desirable. Chinese medicines (CMs, including plants, animal parts and minerals) have drawn a great deal of attention in recent years for their potential in the treatment of HCC. Most studies have shown that CMs may be able to retard HCC progression with multiple actions, either alone or in combination with other conventional therapies to improve quality of life in HCC patients. Additionally, CMs are used for preventing HCC occurrence. The aim of this study is to review the potential prophylactic and curative effects of CMs on human HCC and the possible mechanisms that underlie these pharmacological actions. Publications were collected and reviewed from PubMed and China National Knowledge Infrastructure from 2000 to 2014. Keywords for literature searches include "Chinese medicine", "Chinese herb", "traditional Chinese Medicine", "hepatocellular carcinoma" and "liver cancer". CMs in forms of pure compounds, isolated fractions, and composite formulas are included. Combination therapies are also considered. Both in vitro and in vivo efficacies of CMs are being discussed and the translational potential to bedside is to be discussed with clinical cases, which show the actions of CMs on HCC may include tumor growth inhibition, antimetastatic activities, anti-inflammation, anti-liver cancer stem cells, reversal on multi-drug resistance and induction/reduction of oxidative stress. Multiple types of molecules are found to contribute in the above actions. The review paper indicated that CMs might have potential to both prevent HCC occurrence and retard HCC progression with several molecular targets involved.

3.The development of anti-HIV-1 drugs.
Acta Pharmaceutica Sinica 2010;45(2):165-176
Human immunodeficiency virus type 1 (HIV-1) is the causative agent of acquired immunodeficiency disease syndrome (AIDS). After over 26 years of efforts, there is still not a therapeutic cure or an effective vaccine against HIV/AIDS. The clinical management of HIV-1 infected people largely relies on antiretroviral therapy (ART). Although highly active antiretroviral therapy (HAART) has provided an effective way to treat AIDS patients, the huge burden of ART in developing countries, together with the increasing incidence of drug resistant viruses among treated people, calls for continuous efforts for the development of anti-HIV-1 drugs. Currently, four classes of over 30 licensed antiretrovirals (ARVs) and combination regimens of these ARVs are in use clinically including: reverse transcriptase inhibitors (RTIs) (e.g. nucleoside reverse transcriptase inhibitors, NRTIs; and non-nucleoside reverse transcriptase inhibitors, NNRTIs), protease inhibitors (PIs), integrase inhibitors and entry inhibitors (e.g. fusion inhibitors and CCR5 antagonists). Here, we intend to provide updated information of currently available antiretroviral drugs for ART to promote the development of novel anti-HIV-1 drugs.

AIM:To observe the changes of macular thickness in patients after cataract operation.
METHODS: A total of 126 patients ( 133 eyes ) were divided into two groups that were included in this study. The group (68 eyes of 64 case) with phacoemulsification combined intraocular lens implantation and ( 65 eyes of 62 cases ) with manual small incision cataract surgery ( MSICS) . There was no complication before and during the surgery. Optical coherence tomography ( OCT) was examined 1, 3mo before and after surgery. The visual acuity and macular thickness were compared after surgery. The SPSS 17. 0 software was used for statistical analysis. The paired t-test was used before and after surgery. Independent-samples t test was used in two groups before and after surgery,α=0. 05.
RESULTS: The cataract phacoemulsification group:preoperative and 1mo after surgery, the mean macular thickness was 241. 3±10. 9μm and 279. 7±16. 5μm, with significant difference ( P < 0. 01 ). The mean macular thickness was 245. 6±12. 6μm 3mo after surgery without statistical difference compared with preoperative ( P>0-05). The mean macular thickness was 279. 7±16. 5μm 1mo after surgery and 245. 6±12. 6μm 3mo after surgery with statistical difference(P<0. 05). Three eyes displayed cystoid macular edema at 1mo after surgery and 2 eyes of them was resolved 3mo after surgery. The group of MSICS: preoperative and 1mo after surgery, the mean macular thickness was 240-5±11. 9μm and 280. 7±16. 8μm, with significant difference (P<0. 01). The mean macular thickness was 246. 6±13. 2μm 3mo after surgery without statistical difference compared with preoperative ( P >0-05). One month after surgery and 3mo after surgery, the mean macular thickness were 280. 7±16. 8μm and 246-6±13. 2μm, with statistical difference (P<0. 05). Two eyes displayed cystoid macular edema at 1mo after surgery and 2 eyes were resolved 3mo after surgery. Between the two groups pre-operation or after operation for 1, 3mo respectively P values were without statistical difference (P>0. 05).
CONCLUSION: The macular thickness and macular edema can be found 1mo after cataract phacoemulsification and MSICS. Three months post-operatively, macular edema disappears and does not show statistical difference compared with preoperative. The increase of macular thickness has no obvious relationship with the choice of surgery.
6.Minimally invasive surgery for maximally invasive tumors—pelvic exenterations for rectal cancers: are we prepared?
Journal of Minimally Invasive Surgery 2022;25(4):127-128
Despite the public awareness of colorectal cancer screening with more and more early premalignant or malignant lesions detected, surgeons still face the challenges of operating for a patient suffering from locally advanced rectal carcinoma which required pelvic exenterations, and surgical outcomes mostly influenced by margin status, adjuvant chemotherapy, positive lymph nodes and liver metastasis, etc. Open pelvic exenteration has been the adopted approach in the past and laparoscopic surgery is another option in expert centers. A study in this issue of the Journal of Minimally Invasive Surgery demonstrated promising results of minimally invasive approaches for pelvic exenteration in patients with locally advanced rectal carcinoma, with overall complication rate of 28.2% with a 7.3% circumferential resection margin positivity and with no distal margin involvement, with local recurrence rate of 8.1% and overall survival of 85.2% by 2-year follow-up. We are expecting more results in the future to support the routine implementation of minimally invasive pelvic exenterations.
7.The Ethical Principles of Science and Technology Need Concrete Research to Guide
Chinese Medical Ethics 2022;35(5):475-478
On March 20, 2022, the General Office of the CPC Central Committee and the General Office of the State Council issued The Opinions on Strengthening Ethical Governance of Science and Technology, which put forward five ethical principles of science and technology: promoting human well-being, respecting the right to life, adhering to fairness and justice, reasonably controlling risks and maintaining openness and transparency. Ethical principles require to be studied and interpreted concretely by ethical scholars, that is, first, they need to be refined in order to be truly guided; second, the principle of balance is needed to truly guide; third, it is necessary to study ethical theory in order to truly guide; fourth, it is significant to explore Chinese civilization in order to truly guide. In this way, the ethical principles of science and technology can be practically applied and guide the concrete practice of science and technology.

Asia-Pacific is one of the most densely populated regions of the world and is experiencing rapid economic changes and urbanization. Environmental pollution is a significant problem associated with the rapid modernization of many cities in South Asia. It is not surprising that the prevalences of asthma and allergies are increasing rapidly, although the underlying reasons remain largely unknown. Many studies from this region have documented the changing prevalence of allergic diseases in various parts of the world. However, the methodologies used were neither standardized nor validated, making the results difficult to evaluate. The International Study of Asthma and Allergies in Childhood (ISAAC) has provided a global epidemiology map of asthma and allergic diseases, as well as the trend of changes in the prevalence of these diseases. Allergic sensitization is extremely common in many Asian communities. However, the prevalence of allergic diseases remains relatively rare. The rapid urbanization in the region, which increases environmental pollution and can affect the rural environment, will likely increase the prevalence of asthma and allergies in Asia.

OBJECTIVETo establish a profile of the causes of apparently unexplained SS in genetic referral center and evaluate the current referral system.
METHODSThis was a retrospective database survey on patients who were referred our clinical genetic service from 1988 - 1998 primarily because of SS. We retrieved the study population from our computer database using "short stature"as a search handle and then studied the demographic, clinical and laboratory data from their medical records.
RESULTSThree hundred and fifty-three subjects were referred for genetic evaluation of SS in 1988 - 1998. The mean age of referred subjects was 11.5 years and the female to male ratio was 7.6. All referrals had undergone cytogenetic studies to exclude chromosomal abnormalities, 19% of girls with apparently unexplained short stature had Turner syndrome; at least 47.9% of the study population were normal variants and 25% of the referrals had inadequate information for classification.
CONCLUSIONSGenetic investigation is essential in the management of patients with SS, especially for girls suspected of having Turner syndrome, in which growth hormone treatment has shown to improve final height. We also highlight the inherited causes of short stature, which were often misdiagnosed as benign familial short stature, and discussed the drawbacks of the current referral system.
